七、介词：

1、介词的主要用法：

介词是一种虚词,不能独立使用。介词之后一般有名词或代词(宾格)或相当于名词的其他词类、短语或从句作它的宾语,即构成介词短语。有些介词是由两个以上的词构成的短语介词,如：out of(从…中出来), because of(因为), away from(距离…), on top of(在…顶上), ever since(自从…), next to(在…隔壁), according to(根据…), in front of(在…前方)等。

2、介词的分类表： (见下表)

地点(位置、范围)介词：above在…前, about在…附近, across在…对面, after在…后面, against倚着..., along在…近旁, among在…中间, around在…周围, round在….周围, at在…处, before在...前, behind在...后, below低于..., beside在...旁边, between在...之间, by在...旁, down在...下面, from来自..., in在...里面, inside在...里面, near靠近..., of在...之中, on在...上面, out of在...之外, outside在....外面, over在....上方, under在...下方, up在...上面, on top of在...顶部, in front of在...前, close to靠近..., in the middle of在...的中间, at the end of在...的末端,等等。

方向(目标趋向)介词：across横越..., against对抗..., along沿着..., around绕着..., round环绕..., at朝着..., behind向…后面, etween…and…从…到...,by路过/通过..., down向…下, for向..., from从/离..., in进入..., into进入..., inside到...里面, near接近..., off脱离/除..., on向...上, out of向...外, outside向....外, over跨过..., past经过/超过..., through穿过..., to向/朝..., towards朝着..., on to到...上面, onto到...上面, up向...上, away from远离...

方式介词：as作为/当作..., by用/由/乘坐/被..., in用…(语言), like与…一样, on骑(车)/徒(步),通过(收音机/电视机), over通过(收音机), through通过..., with用(材料),用(手/脚/耳/眼), without没有…

涉及介词: about关于..., except除了…, besides除了…还... for对于/就…而言, in在…(方面), of…的,有关..., on关于/有关..., to对…而言, towards针对..., with就…而言

3、介词短语的句法作用：

介词短语相当于一个形容词或副词,可用作状语、定语和表语。如：The man came .(状)(那个人走下楼来)/The woman is from the countryside.(定)(头上戴花的妇女来自乡下)/The teacher is now with the pupils.(表)(老师现在和学生在一起)

4、介词短语在句子中的位置：

介词短语做状语时,如果表示时间/地点,可以放在句首或句尾,如果表示方向/方式/伴随/涉及/原因/目的/比较,一般放在句尾； 介词短语作表语时放在连系动词之后；介词短语作定语时,只能放在被修饰的名词之后。如：He wanted to find a good job in Shanghai the next year.(状语)(他想来年在上海找份好工作)/ They searched the room for the thief.(他们在房间里搜索小偷) / The letters are for you.(表语)(信是给你的)/ Have you seen a cat with a black head and four white legs?(定语)(你看见一只黑头白腿的猫了吗？)

5、重要注释：

⑴ this / that / these / those / last / next / a / every / each等词构成的时间短语,前面不用任何介词。如：Every year travellers from abroad come to visit Pingyao.(每年都有国外的游客来游览平窑镇)/ He had a bad cold that week.(那个星期他患重感冒)

⑵ for有时用来引出动词不定式的逻辑主语,常翻译成“对于…而言”。如：It’s too hard for me to finish the work in only one hour.(让我在区区一个小时内完成这项工作太难了)/ The house is big enough for 10 men to live in.(房子够大的可以容10个人住)

⑶ of有时用来表示后面的人物正好是前面的表语的逻辑主语。如：It’s very nice/kind of you to do so.(你这么做真是太好了)

⑷ 介词有时会与它的宾语分离,而且宾语前置。

① 当宾语是疑问词时。Who are you talking about?(你们在谈论谁？)

② 宾语在从句中当连接词时。He has a younger brother who he must take good care of.(他有 一个需要他照顾的小弟。) / Do you know who our teacher is talking with over there?(你知道我们的老师在那边和什么人谈话吗？)

③ 动词不定式作定语且该动词为不及物动词,后面有介词。I finally found a chair to sit on.(我 最终找到了一张椅子坐。)

(5) 记住一些固定词组：arrive at/in(到达…),on foot(步行),not…at all(根本不),to the north of(在…以北),in the east of(在…的东部),in the night(在夜间),at night(在晚上),be afraid of(害怕…),be full of(充满/ 装满….),be filled with(充满/ 装满….),be good/bad for(对…有益/有害),be made of(由…做成),be made from(由…制造),play with(玩耍……),look out of(朝…外面看),at the end of(在…末梢/结束时),by the end of(不迟于…/到…末为止),with the help of或with one’s help(在…的帮助下),look after(照料…),look for(寻找…),on a bike(=by bike)骑车, help sb. with(帮某人做…),get on (well) with(与某人相处[融洽]),等等。

6、某些介词的用法辨析：

⑴ 时间或地点介词in、on、at的用法区别：表示时间时, in表示在一段时间里(在将来时句子中则表示在一段时间之后), on表示在具体的某一天或者某天的上下午等, at表示在某个时刻或者瞬间； 表示地点时, in表示在某个范围之内, on表示在某个平面上或与一个面相接触,at则表示在某个具体的场所或地点。如：He was born on the morning of May 10th.(他出生于五月十日的早晨)/ I usually get up at 7：00 in the morning.(我通常在早上的七点钟起床) / His glasses are right on his nose.(他的眼镜就架在他的鼻子上)/ He is at the cinema at the moment.(此刻他正在电影院)

⑵ after与in表示时间的用法区别：“after+(具体时刻/从句)”表示“在…时刻之后”常用于一般时态；“in+(一段时间)”表示“在(多久)之后”,常用于将来时态。如：He said that he would be here after 6：00.(他说他六点钟之后会来这儿)/ My father is coming back from England in about a month.(我父亲大约一个月以后从英国回来)

⑶ since与for表示时间的用法区别：“since+(具体时刻/that-从句)”表示“自从…起一直到现在”,“for +(一段斶间)”表示“总共有…之久”,都常用于完成时态；如：Uncle Li has worked in this factory since 1970.(李叔叔自从1970年起就在这家工厂工作了)/ Uncle Li has worked in this factory for over 30 years. (李叔叔在这家工厂已经工作了30多年)

⑷ by、in与with表示方式的用法区别：都可以表示“工具、手段”,但是by主要表示“乘坐”某个交通工具或“以……方式”,在被动句中可以表示动作的执行者；in表示“使用”某种语言/文字,with表示“使用”某个具体的工具、手段。如：We see with our eyes and walk with our feet.(我们用眼睛看东西,用双脚走路)/ Please write that article(文章) in English.(请你用英语写那篇文章)/ Let’s go to the zoo by taxi.(我们打的去动物园吧。)/ It was written by Lao She.(那是老舍写的)

⑸ about与on的用法区别：都可以表示“有关…”,但是about的意义比较广,而on主要表示“有关…(专题/课程)”。如：Tom is going to give a talk on the history of America.(汤姆要作一个美国历史的报告)/ They are very excited talking about the coming field trip.(他们兴致勃勃地谈论着即将来到的野外旅游)

⑹ through与across、over的用法区别： through指“穿过…(门洞/人群/树林)”； across和over可以指“跨越…(街道/河流)”,可互换,但是表示“翻过…”时只能用over. 如：Just then a rat (鼠)ran across the road.(就在那时一只老鼠跑过路面)/ There is a bridge across/over the river.(河上有座桥)/ They climbed over the mountain and arrived there ahead of time.(他们翻过大山提前到达了那里)/ The visitors went through a big gate into another park.(参观者们穿过一个大门来到另一个公园)

(7)as与like的区别：两个词都表示“像……”,但是as译为“作为……”,表示的是职业、职务、作用等事实,而like译为“像……一样”,表示外表,不是事实。如：Let me speak to you as a father.(我以父亲的身份和你讲话。)(说话者是听者的父亲) / Let me speak to you like a father.(让我像一位父亲一样和你讲话)(说话者不是听者的父亲)

(8)at the end of、by the end of、to the end、in the end的用法区别：at the end of…既可以表示时间也可以表示地点,译为“在…末；在…尽头”,常与过去时连用；by the end of…只能表示时间,译为“在…前；到…为止”,常用于过去完成时； in the end与at last基本等义,表示“终于、最后”,通常用于过去时；to the end译为“到…的终点为止”,前面往往有表示运动或连续性的动词。如：By the end of last term we had learned 16 units of Book III.(到上学期期末我们已经学习了第三册16个单元)/ At the end of the road you can find a big white house with brown windows.(在路的尽头你能找到一幢有棕色窗户的白房子)/ They left for Beijing at the end of last week.(上周末他们动身去了北

京)/ In the end he succeeded in the final exams.(他最终在期末考试中考及格了)/ We should go on with the work to the end.(我们应该把工作干到底)/ Follow this road to the end and you will see a post office.(沿这条路走到底就能看见一家邮电局)

(9)for a moment、for the moment、in a moment、at the moment的区别：for a moment“一会儿、片刻”(=for a while),常与持续性动词连用；for the moment“暂时、目前”,常用于现在时；in a moment“一会儿、立即、马上”(=soon; in a few minutes),一般用于将来时；at the moment“此刻,眼下”(=now),用于现在进行时。如：Please wait for a moment.(请稍等)/ Let’s leave things as they are for the moment.(暂时就维持现状吧！) / I’ll come back in a moment.(我过会儿回来)/ I am very busy at the moment.(眼下我很忙)

(10)but的问题：用介词but引出另一个动词时,要注意：如果前面有do,后面就用原形动词,前面没有do时,后面的动词要加to。如：I could do nothing but wait.(我什么也做不了只能等) / They had no choice(选择) but to fight.(他们没有选择只有战斗)

(11)in front of 与in the front of： in front of“在…的前面”, 与in the front of“在…的前部”。如：A car was parking in front of the hall.(大厅跟前停着一辆汽车)/ In the front of the hall stood a big desk.(大厅前部立着一个大讲台)

(12)except与besides的区别：except“除了”,表示排除掉某人物,即不包含；而besides“除了”则表示包含,即“不仅……又……”。如：Everyone went to the Palace Museum except Tom.(除了Tom,大家都去了故宫博物院)(Tom没有去故宫)/ Besides Chinese he also studied many other subjects.(除了汉语之外,他还学其他许多功课)(“汉语”也是他学的功课之一)

八、动词

1、动词的分类：

实义动词 含有实在的意义,表示动作或状态,在句子中能独立作谓语。 She has some bananas. 她吃些香蕉。

They eat a lot of potatoes. 他们常吃土豆。

连系动词 本身有一定的词义,但不能独立作谓语,必须和表语一起构成谓语。

His father is a teacher.他父亲是教师。The teacher became very angry. 老师变得很生气。

助动词 本身没有词义,不能独立作谓语,只能和主要动词一起构成谓语动词,用来表示否定、疑问、时态、语态或其它语法形式,助动词自身有人称、单复数和时态的变化。He doesn’t speak English. 他不说英语。

情态动词 本身有一定的意义,不能独立作谓语,只能和主要动词一起构成谓语动词,表示说话人的语气和情态。情态动词没有人称和单复数的变化,有些情态动词有过去式。

You can keep the books for two weeks.

这些书你可以借两个星期。May I smoke here? 我可以在这儿抽烟吗？We must go now. 我们现在得走了。

★重要注解：

(1) 关于实义动词： ① 英语的实义动词又可分为及物动词和不及物动词两大类：

后面必须跟宾语意义才完整的叫及物动词；本身意义完整,后面不需跟宾语的叫不及物动词。

② 有些动词通常只作不及物动词。如：go,come,happen,lie,listen,rise,arrive,hall等。

有些动词通常用作及物动词。如：say, raise, lay, find, buy等。

③ 大多数动词可以兼作及物动词和不及物动词。如：study, sing等。

④ 有些动词作及物动词与作不及物动词时的意义有所不同。如：know, wash等。

⑤ 有些动词常和介词 、副词或其它词类一起构成固定词组,形成短语动词。如：listen,reply,wait,look.

(2) 关于连系动词：

①连系动词用来连接主语和表语,连系动词后面常为形容词。

②常见的连系动词有：be、become、look、feel、sound、smell、taste、seem、turn、grow、get、 go、fall、sit、stand、lie 等。

③有些连系动词来源于实义动词,意思也跟着变化：look(看→看起来)、feel(感觉、摸→感到)、 smell(闻、嗅→闻起来)、taste(尝→尝起来)、turn(翻转、转动→变得)、grow(生长→变得)、get(得到、到达→变得)、go(去→变得),所不同的是,作为实义动词时,后面不能跟形容词。

[注释]

become、get、go、be、grow、turn的用法区别：become表示“变成”,比较正式,通常不用将来时表示动作已经完成。get也表示动作已经完成,但是更加口语化,通常表示温度、时间、岁数等变化。go表示“变得”,常见于某些短语中,后面常有形容词bad、blind、hungry等。be表示“是、成为、当”,多用于将来时、祈使句或不定式中。grow表示“变得”,常指逐渐的变化,表示身高、岁数的增长。turn表示“变得”,指变为与原先不同的情况,通常指颜色等变化。如：I was caught in the rain and I became ill.(我淋雨感冒了)/ He has got rich.(他变富了)/ He will be a scientist in the future.(将来他将成为科学家)/ My little brother has grown much taller in the past year.(在过去的一年里我的弟弟长得高多了)/ The sandwich has gone bad.(那块三明治已经变坏)/ Her face turned red after her mother criticized(批评) her.(妈妈批评了他以后他的脸变红了)

(3) 关于助动词：

①常见的助动词有：用于进行时和被动语态的be (am, is, are ,was, were, been, being ) ;用于完成时的have(has,had,having) ;用于将来时的shall (should) ; will (would)和用于一般时的do(does,did) .

②助动词必须同主语的人称和数一致,也就是说因主语人称、数的不同而采用不同的形

式,其中有些助动词也可作情态动词。如：shall, will, should, would.

(4) 关于情态动词：

①常见的情态动词有：can (could) ,may (might), must ,shall (should), will (would), dare (dared) , need等,另外,have to、had better也当作情态动词使用。情态动词后面必须加动词的原形。

②can表示体力、脑力方面的能力或客观的可能性。常用“can”代替“may”。情态动词“can”的过去式是“could”,否定式是“can’t”,“could”的否定式是 “couldn’t”。如：Can I help you?(要帮忙吗？)/ He can swim.(他会游泳)/ That can’t be Mr Li.(那不可能是李先生)

③ may表示允许、请求或可能性,用may提问时,肯定回答一般用Yes,you may.;否定回答一般用can’t或mustn’t. 如：May I ask you a question?—Certainly.(可以问你一个问题吗？当然可以)/ You may go now.(现在你可以走了)/ It may be in your pocket.(它可能在你的衣袋里)

④ must表示“必须”、“一定”的意思。表示“必须”时否定形式是mustn’t；表示“一定”时,否定形式是“can’t” 如：We must be very careful when we cross the road.(我们过马路时一定要非常小心)/ It must be Jack.(那准是杰克)/ I haven’t seen Kate today. She can’t be here.(我今天没有看到过凯特,她不可能在这里)

[注意]用must(必须)进行提问时,肯定回答用must,否定回答用needn’t；用must(一定)进行提问时,肯定回答仍用must,但是否定回答用can’t.如：Must we clean the room

before we leave? –Yes,you must.或No,you needn’t.(我们走之前必须要打扫房间吗？是的,必须打扫。/ 不,不需要。) / Must she be in the romm? –Yes,she must.或No,she can’t.(她一定在房间里吗？是的,一定。/ 不,不可能在。)

⑤ “have to”表示“不得不”、“必须”。We’ll have to leave now for it is very late at night.

have to的疑问形式是：助动词+…+have to,否定形式是：助动词+not+have to或者用needn’t.如：Do you have to stay until 8 o’clock?(你得呆到8点钟吗？)/ You don’t have to do so.(=You needn’t do so.)(你不用这么做)

⑥ shall在问句中,可表示征求对方意见,与第一人称连用；在陈述句的第二、三人称的主语后或表示“命令”、“警告”、“允许”等。如：Shall we go to the zoo this weekend?(我们这个周末去动物园好吗？)/ He shall bring his own book next time.(他下次必须带自己的书来)

⑦ should可表示“劝告”、“建议”、“惊奇”等意思。We should speak to old people politely.

⑧ will表示“意愿”、“决心”等意思,一般与第二人称连用。如：Will you please close the door for me?(请你替我把门关上好吗？)/ I will teach you a lesson.(我要教训你一顿)

⑨would表示过去的“意愿”、“决心”等。He would sit near the fire every time he returned home.(每次他回到家中总要坐在火炉边)

would也可以表示现在的情况,表达说话人向对方提出的要求,语气比“will”婉转客气。“我想要…”通常用“I would like to”或“I should(I’d) like to”来表示。

如：Would you like to have a rest at the moment?(你现在想要休息一下吗？)

would还可以表示过去经常发生的事情。如：Every year parents would tell their children about the boy who would save his people.(每一年父母们总是向孩子们讲述这个将会拯救他的人民的男孩的事)

⑩ need表示“需要”,用于疑问句或否定句。“need”作实义动词时,在肯定、否定、疑问句中都可以用。如：He needn’t do it in such a hurry.(他不需要如此匆忙地做这件事)/ He needs some help.(他需要一些帮助)

⑿ ‘d better (do)(“最好是”)一般也当作情态动词使用,否定式是：’d better not (do). 如：You’d better sit here and say nothing.(你最好坐在这儿不讲话)/ You’d better not speak because he is sleeping.

2、动词词形变化一览表：

(1)规则动词变化表：

注意：在加ing或ed时动词如果以“r”结尾,尾音节又重读的动词,“r”应双写。

疑问句将am /is /are /will /have /has /was /were /had /would 提前到句首。

5、八种时态的具体用法：

①一般将来时的时间状语有：tomorrow,this (afternoon),next (year),one day,now,soon,

someday,sometime, in the future, when引导的从句等。

② 用will构成的将来时,表示动作与人的主观愿望无关。“shall”用于第一人称“,will”

用于所有人称。如：I will graduate from this school soon.(我很快就要从这所中学毕业了)/ You will stay alone after I leave.(我走了之后你就要一个人过了)

③ “am/is/are going to+动词原形”表示打算或准备要做的事情,或者主观判断即将要发生的事情,而“am/is/are to +动词原形”表示安排或计划中的动作。如：A man told them that the woman was to give birth to the special baby.(有一个人告诉他们那个妇女就会生下那个特别的男孩)/ It’s going to rain soon.(天快要下雨了)

⑦ “be to +动词原形”表示按照计划将要发生的事情。如：An angel came to tell her that she was to have this special boy.

(4)现在进行时 现在进行时表示现在正在进行的动作或是现阶段正发生而此刻不一定在进行的动作。

① 现在进行时由“助动词be (am is are ) +现在分词”构成。

② 现在进行时的时间状语有： now, this …, these…等,但经常不用。如：What are you doing up in the tree?(你在树上干什么？)/ I am writing a long novel these days.(我最近在写一本长篇小说)

③ 表示即将发生的动作,一般指近期安排好的事情。常见的动词有：come, go, stay, leave, spend, do等。如：I’m coming now.(我就来)/ What are you doing tomorrow?(你明天干什么？)/ He is leaving soon.(他就要走了)

④ 表示频繁发生或反复进行的动作,常与always等频度副词连用,以表示赞扬、不满或讨厌等感情色彩。如：He is always borrowing money from me and forgetting all about it some time later.(他老是向我借钱,过一些时候就忘得一干二净)

(5)过去进行时 过去进行时表示过去某一时刻或某阶段正在进行的动作。

① 过去进行时由“was(第一、三人称单数)或were(第二人称单数和各人称的复数)+现在分词”构成。

② 过去进行时的时间状语有：then, at that time, this time yesterday, at (eight) yesterday (morning),(a year) ago, 以及由when引出的时间状语从句。如：He was cooking supper this time yesterday.(昨天这个时候他正在做晚饭)/ The little girl was playing with her toy when I saw her.(我看到小女孩的时候她正在玩玩具)

③ 用于宾语从句或时间状语从句中,表示与主句动作同时进行而且是延续时间较长。句子中通常不用时间状语。如：She was it happen when she was walking past.(她路过时看到事情的发生)/ They sang a lot of songs while they were walking in the dark forest.(他们在黑暗的森林里走时唱了很多歌)

④ 也可以表示过去一个阶段频繁发生或反复进行的动作,常与always等频度副词连用,以表示赞扬、不满或讨厌等感情色彩。如：He was always borrowing money from me when he lived here.(他住在这里时老向我借钱)

(6)现在完成时 现在完成时表示一个发生在过去的、对现在仍有影响的动作,或表示开始在过去,并且一直延续到现在,甚至还可能延续下去的动作。

①在完成时由“助动词have (has)+动词的过去分词”构成。

②表示发生在过去的对现在仍有影响的动作时,时间状语有：already, yet, just, once,

twice,ever, never,three times, before等。如：I have never seen such fine pictures before. (我以前从来没有看过这么好的画)/ He has just gone to England.(他刚去英国)

③表示在过去开始一直延续到现在(可能延续下去)的动作或状态时,时间状语有：for (two years),since 1990, since (two weeks ago)和since引导的状语从句。如：I have been away from my hometown for thirty years.(我离开家乡有30年了)/ Uncle Wang has worked in the factory since it opened.(自从这家工厂开张,王叔叔一直在那儿工作)

④口语中have got往往表示have(有)的意思。如：They have got thousands of books in their library.(他们图书馆有上万本书)

⑤have been to与have gone to的区别：have gone to(“已经去了”)表示人不在这里,have been to(“去过”)表示人在这里。如：--Where is Mr Li? –He has gone to the UK.(李先生在哪里？他去了英国。)/ --Do you know something about Beijing? –Yes,I have been to Beijing three times. (你知道北京的情况吗？是的,我去过那里三次。)

⑥在完成时中,一个瞬间性动词(一次性动作)不能与表示一段时间的状语连用,此时须将该瞬间动词改为延续性动词或状态动词。具体变化见下表：

瞬间性动词的完成时 → 延续性动词或状态动词的完成时

have (already) gone to… have been in / at … for (two years)

has come to… has been here since (1990)

(had) left… (had) been away from…

arrived… been in…

died been dead

begun been on

ended been over

bought... had…

borrowed… kept…

joined… been in …

或者使用下面这个句型：

It is / has been + (多久)+ since + 主语(人)+谓语(过去时)+……+过去时间状语

[注意] 在其它的时态中也存在类似问题,记住,关键是：瞬间动词不能和表达一段时间的状语连用。如：How long may I keep the book?(这本书我能借多久？)(句子中keep取代了borrow)

(7) 过去完成时 过去完成时表示过去某一时间或某一动作发生之前已经完成的动作。简言之, 过去完成时所表示的时间是“过去的过去”。

①过去完成时由“助动词had+动词的过去分词”构成。

②过去完成时时间状语有：by (yesterday), by then, by the end of (last…)或者由when,before等引出状语从句。有时句子中会有already, just, once, ever, never等词语,也会有for… 或since…构成的时间状语。如：They had already finished cleaning the classroom when their teacher came.(当老师来的时候他们已经打扫完了教室)/ The woman had left before he realized she was a cheat.(在他发觉那个妇女是个骗子时她已经走掉了)

③过去完成时常用于宾语从句中、after引导的从句中,或者从句是before引导的主句中。如：After I had put on my shoes and hat,I walked into the darkness.(我穿上鞋子戴上帽子走进了黑暗之中)/ He said that he had never seen a kangaroo before.(他说他以前从来没有见过袋鼠)

(8) 过去将来时 过去将来时表示在过去预计将要发生的动作或存在的状态。

①过去将来时由“助动词should(第一人称)或would(第二、三人称)+动词原形”构成。在美国英语中,过去将来时的助动词一律用“would +动词原形”。

②过去将来时常由于宾语从句中,时间状语有：later, soon, the next (day).

③在时间状语从句和条件状语从句中不可以使用过去将来时,而应该使用一般过去时。如：He promised that he would pay me a lot if I helped him with the project.(他答应付给我许多钱如果我帮助他搞那个项目)/ Every time when he was free,he would sit down and read some books.(每次只要他有空他就会坐下来看看书)

④表示纯粹的将来时用would或should,表示打算或主观认为的事情用was/were

going to (+动词原形)。如：She told me she would be 18 the next month.(她告诉我她下个月就18岁了)/ She told me that she was going to have a walk with her pet dog.(她告诉我她打算带她的宠物狗去散步)

⑤过去将来时还可以表示一个过去经常性的动作。如：When it rained in the day, he would bring an umbrella with him.(白天下雨时他会随身带一把雨伞)

(9)现在完成进行时：现在完成进行时指一个从过去就开始一直延续到现在并由可能继续下去的动作,它具有现在完成时和现在进行时双重特征,结构是：“have/has + been +动词的现在分词”。如：I have been swimming in the cold water for about two hours.(我已经在冰冷的水里游了将近两个小时)/ How long have you been waiting here?(你在这里一直等了多久？)

6、被动语态：

(1)被动语态定义：被动语态是动词的一种特殊形式,用来说明主语与谓语动词之间的关系。如果主语是 动作的执行者(即某人做某事),便叫主动语态；如果主语是动作的承受者(即某事被做),便叫被动语态。主动与被动的区别不是词序的区别,而是主语与谓语意义上的区别。在英语中只有及物动词和一些相当于及物动词的词组才有被动语态的形式。

(2)英语中被动语态由“助动词be +动词的过去分词”构成。助动词be有时态、人称和数的变化。被动语态后的by短语有时可省去。

(1) 被动语态的用法：

① 不知道谁是动作的执行者(即不知道谁做)时用被动语态,省略by短语。如：A man was killed in the accident.(一个人死于事故)/ This window was broken yesterday.(这扇窗子是昨天被打破的)

②不说或者众所周知是谁做时,用被动语态,省略by短语。如：Rice is also grown in this place.(这个地方也种水稻)/ A railroad will be built here in three years.(三年之后这里将要修建一条铁路)

③强调动作的承受者,句尾加by短语。如：It was written by Lu Xun.(它(书)是鲁迅写的)/ A pet dog is never killed by its owner.(宠物狗是不会被主人宰杀的)

(2) 主动语态如何改写为被动语态：

主动句： 主语(人/物) + 谓语(及物动词) + 宾语(人/物) + 其他 + 状语

(动作的执行者) (各种时态形式) (动作的承受者)

被动句： 主语(人/物) + 谓语(及物动词) + by +人 / 物 + 其他 + 状语

(动作的承受者) (be +过去分词) (动作的执行者)

(3) 注意点：

①“动词+间接宾语+直接宾语”改为被动时,可以用间接宾语做被动句的主语。如：

His teacher gave him a dictionary.→He was given a dictionary by his

teacher.(老师给他一本字典→他得到老师一本字典)

也可以用直接宾语做被动句的主语,但是需用to或者for引出原句的间接宾语。如：His teacher gave him a dictionary.→A dictionary was given to him by his teacher.(老师给他一本字典→一本字典由老师送给了他)/His father made him a kite.→A kite was made for him by his father.(他的父亲给他做了一个风筝→一个风筝由他的父亲做给了他)

②“动词+宾语+动词原形”改为被动时,动词原形前要加to.如：The boss made the poor man work 12 hours a day.→The poor man was made to work 12 hours a day.(老板让这个可怜的人一天工作12小时→这个可怜人被迫一天工作12小时)

③“动词+…+介词”改为被动时,介词一般在原位不动。如：The girl takes good care of her little brother.→The girl’s little brother is taken good care of by her.(女孩照顾小弟弟→女孩的小弟弟由她照顾着)

④“be+过去分词”未必表示被动语态,而可能是系表结构。如：

He is pleased / worried / tired /…….(系表)(他高兴/焦虑/疲劳……)

He was hit / knocked down / told / shot / …….(被动)(他被击中/撞倒/关照/射中……)

7、动词的非谓语形式：动词不做谓语时的固定形式。

(1)动词的非谓语形式包括动词不定式、动名词和分词三种形式；其中分词又包含现在

分词和过去分词两种形式。它们在句子中不能单独作谓语。

(2)动词不定式：

① 形式：动词不定式基本形式由“不定式记号to+动词原形”构成。它的否定形式只要在“to” 前面加上“not”。它的疑问形式是：“wh-疑问词+to+动词原形”。*它的被动形式：“to be +过去分词”。*它的完成形式：“to have +过去分词”。

② 动词不定式具有名词、形容词和副词的特征,即可以在句子中作主语、宾语、定语、状语、表语和宾语补足语。但不定式也保留动词的某些特征,即不定式后面可以跟宾语、表语和状语。动词不定式加上相关成分就构成不定式短语。

③动词不定式可以放在谓语前句子作主语。但是通常将作主语的动词不定式或不定式短语放在谓语后面,而在主语位置用“it”作形式主语(有时在不定式的前面还会用for sb.表示不定式的逻辑主语)。如：To help animals is helping people.帮助动物就是帮助人/ It is very difficult (for us) to learn Chinese well.((对于我们而言)学好汉语是非常的困难)/ It took me half an hour to work out this problem.(解出这道题花了我一个小时的时间)

④ 动词不定式可以作谓语动词(及物动词)的宾语。

[A] 及物动词+不定式一般形式：

谓语动词(vt.) +不定式

(作宾语) [说 明]

want(想) / try(试图) / decide(决定) / would like(想要) / hope(希望) / love(喜爱) / learn(学会) / afford(提供) / agree(同意) / fail(失败、未能) / mean(意味着) / prefer(宁愿) / wish(希望) + to (do) (无)

help(帮助) to可以省略

begin(开始)/ start(开始)/hate(憎恨) 也可跟动名词,意义变化不大

forget(忘记) / remember(记得)/ like(总爱) 也可跟动名词,意义变化较大

如：I would like to have a rest at the moment.(我现在想休息一下)/ They began to search the room for the thief.(他们开始在屋子里搜寻小偷)/ He liked to have a swim in the pool near his house.(他喜爱在靠家的水塘里面游泳)/ When did you learn to speak English?(你什么时候开始学英语的？)/ Don’t forget to close the door when you leave.(你离开时别忘了关门

[比较] He forgot to turn off the light.(他忘了关灯.) (没关)/ He forgot turning off the light.(他忘记关过灯.)(关了) / Please remember to ring me up.(记得给我打电话.)(还没打电话) / I remember calling you yesterday but you forgot.(我记得昨天给你打电话了,但是你忘记了.)(打过电话)

[B] 及物动词+疑问词+不定式：

谓语动词(vt.) +wh-疑问词+不定式 (作宾语) [说明]

tell (告诉) / show (显示) / know (知道) / ask (问) / find out (发现) / understand (明

白) / wonder(疑惑) / learn(学会) / forget(忘记) / remember(记得) / teach sb.(教某人) / discuss(商讨)+ how + to (do)

which…… 不定式疑问形式还可以作句子的主语、表语等。

如：He does not know which one to take.(他不知道该选哪个)/ Tell me how to get to the station.(告诉我怎么样去火车站)/ She asked me what to do for today’s homework.(她问我今天家庭作业做什么)/ Can you teach me how to search the internet?(你能教我怎样上网吗？)

[C] 不定式作宾语而后面又有宾语补足语时,通常用it代替作形式宾语,而不定式则后置。如： I found it not very easy to learn to ride a bike.(我发现学骑车不很容易)

⑤ 动词不定式可以在句子中用作定语,放在名词或代词后面。

[A] 记住下面的一些结构：

被修饰部分 + 不定式(作后置定语) 汉 语 意 思

a key to lock the door 锁门的钥匙a box to hold these things装这些东西的箱子give her a book to read

Is there any (+名词/代词) to (do)? 有…要(做的)吗?

It’s time to go. 是走的时间了。/ 该走了。Do you have any work to do? 你有工作要做吗?

I’d like something to eat.我要点儿吃的。I have nothing to say. 我没有话要说。

Would you like something to drink? 你要点儿喝的吗？

[B] 在这种情况下,如果不定式动词是不及物动词,则后面必须加介词。如：

They could not find a place to live in.(他们找不到住的地方)/ Please give me a chair to sit on.(请给我一张椅子坐坐)/ He has got a writing brush to write with.((他找到了写字的毛笔)

⑥ 动词不定式可以在句子中用作状语,有下列几种情况：

[A] 放在不及物动词(come, go, stop, finish, wait等词)的后面。如：He came to see her yesterday.(他昨天来看望她)(表示来的目的)/ I stopped to have a rest.(我停下来休息一会儿)(表示停下来的目的)

[B] 放在完整的谓语之后(即“谓语+宾语”、“谓语+宾语+补语”、“动词+表语”之后)。如：We cleaned the room to let him play in it.(我们打扫了房间以便让他在里面玩)/ I opened the window to see more clearly.(我打开窗子以便看得更清楚点儿)

[C] 有时表示目的的不定式短语可以放在句首。如：To arrive there on time,I got up one hour earlier than usual.(为了按时到达,我们比平时早起了一个小时)(表示早起的目的)

[注意] stop to do 与stop doing的不同。如：They stopped to have a look.(他们停下来看看)(不定式作“停下来”的目的状语)/ They stopped looking out of the window

and began to listen to the teahcher.(他们停止向窗外望,开始听老师讲课)(动名词作宾语,表示“停止”的内容)

⑦ 动词不定式可以在句子中用作表语,限用于连系动词之后。如：My job is to keep the goal.(我的工作就是守住球门)

⑧ 动词不定式可以在句子中用作复合宾语中的宾语补足语。

谓语动词(vt.) + 宾语 (人 / 物)+不定式(作宾语补足语)

ask(请) / tell(关照) / teach(教) / want(想要) / would like(想要) / get(让) / help(帮) / invite(邀请) / like(喜欢) / warn(警告) / +sb. / sth.

+to (do)

make(使得) / let(让) / hear(听) / see(看) / feel(感觉) / watch(观看)/ have(使得) / help(帮助) +sb. / sth.

+ (do)

如：Mum asked me to help her with the cooking.(妈妈叫我帮助她做饭)/ I would like you to see my parents.(我想要你见见我的父母)/ The boss often made the workers work 14 hours a day.(老板常让工人们一天工作14小时)/ Now let me hear you play the violin.(现在让我来听你拉小提琴)

[注意] help之后做宾补的不定式符号to可以省略；hear / see / feel / watch之后的宾补用不定式与现在分词时,含义不同,需特别注意,(参见现在分词部分)。试比较：

I heard her crying when I walked past.(我路过时听到她正在哭)(指当时瞬间的情况)

I sat near her and heard her sing the new song.(我坐在她附近听她唱新歌)(指整个过程)

(3)动名词

① 动名词由动词原形加词尾“ing”构成。动名词有动词的特征,可以跟宾语,可以被状语修饰；它也有名词的特征,在句子中可以作主语、宾语(包括介词宾语)等。动名词加相关词语(宾语或状语等)构成动名词短语。

② 动名词可以作主语。一般可用it作形式主语而将动名词短语后移。如：Learning English all by yourself is not so easy.(自学好英语不那么容易)(=It is not so easy learning English all by yourself.)

③ 动名词可以作宾语。

[A] want / need之后用动名词时,含有被动意思。如：Your car needs reparing badly.(你的车急需修理。)(被修)My hair needs cutting.(我要理发。)(头发被理)

[B] remember / forge / stop / finish之后用动名词时,与用不定式含义不同。如：I forgot to write a letter to him.(我忘了给他写封信)(根本没写) / I forgot writing a letter to him.(我忘了给他写过信)(写了却忘了) / They stopped to look back.(他们停下来向后看)(停下的目的是向后看) / They stopped looking back.(他们停止向后看)(不向后看了)

[C] enjoy / mind / keep / hate/ go等词一般用动名词作宾语。如：Do you mind my closing the door?(把门关上你介意吗？)/ She hates travelling by air.(她讨厌坐飞机旅

行)/ They went swimming every afternoon.(他们每天下午去游泳)/ I enjoy walking around the town.(我喜欢在镇上转悠)

[D] like / love / start / begin / learn后面用动名词时,与用不定式意思相近或相同。如：We began to study English when we were at primary school.(我们在小学时就开始学英语了) / We began studying English when we were at primary school. (我们在小学时就开始学英语了)

④ 动名词可以作表语,此时特别注意不要与现在进行时混淆。如：My job is putting these parts together.(我的事情是把这些部件拼起来) / I am putting these parts together.(我正在把这些部件拼起来)

⑤ 动名词与现在分词构成相同,但是含义不同,动名词主要表示事情,而现在分词则主要表示进行着的动作。如：Eating too much is not good for your health. (动名词短语,作主语) / Seeing is believing.(动名词短语,分别作主语和表语) / He ran after a moving bus and got onto it.(现在分词,作定语) / His father saw him sitting on some eggs.(现在分词,作宾补)

(4)分词： 包含现在分词和过去分词。(高中学习重点)

① 主要区别：现在分词一般有主动的意思或表示动作正在进行的意思；过去分词有被动或动 作已经完成的意思。分词可以有自己的宾语或状语。

② 分词或分词短语在句子中作定语、状语和复合宾语等。

[A] 作定语：分词作定语时,一般要放在修饰的名词之前,分词短语作定语时,则要放在所修饰的名词之后。 如：I have got a running nose.(我流鼻涕) / The woman running after the thief shouted very loudly,“Stop the thief!”(跟着小偷追的妇女大喊：捉小偷！) / Yesterday I met a man called Mr. Black.(昨天我遇见了一个名叫布莱克先生的人)/ He only gave me a broken glass,so I was very angry with him.(他只给了我一个坏玻璃杯,所以我很生他的气)

[B] 现在分词可以作下列动词的宾语补足语。(参考不定式作宾语补足语)

谓语动词(vt.) 宾语 宾语补足语

keep(保持) / see(看到) /

hear(听到) / watch(注意到) / feel(感觉到) sb./sth. (do)ing

如：Mum kept me working all the week.(妈妈让我一个星期都在工作)/ When I entered the room,I saw Jack eating a big pear.(我进入房间时看到杰克正在吃一只大梨子)/ In the dark I felt something very cold moving on my foot.(黑暗之中我感到有个冷的东西在我的脚上移动)

[C] 现在分词可以作状语,表示伴随情况。如：She came into the classroom,holding a pile of papers in her hand.(他走进教室,手上抓着一沓纸)/ I am very busy these days getting ready for the coming oral test.(这些日子我正忙着准备即将来到的口语考试)

[D] 过去分词可以作表语,放在连系动词后面,但要注意不要与被动语态混淆,“主系表”

主要表示状态,而被动语态则表示动作。常用过去分词作表语的结构有：be worried (焦虑) / be pleased (高兴) / be tired (疲劳) / get dressed (打扮好) / get lost (迷路) / get caught (遭遇) / beome frustrated (沮丧) / become intereted in (对…感兴趣)等等。例略。

[E] 过去分词可以作宾语补足语。如：I had my hair cut this morning.(今天早上我让人给我理了发)(注意：have sth. done表示动作由别人来做,而have done sth.则为现在完成时的结构,两个结构不可以混淆)

8、动词用法辨析：

(1)“Why not+动词原形+…?”(干嘛不……?)是简略句,完全形式是：Why don’t you +动词原形+…?如：Why not go and have a look?(干嘛不去看看？)/ Why not try it once again?(为什么不再试试？)

(2) seem(好象)的用法：记住几个结构：①sb./sth. + seem + (to be+)形容词+…；②sb./sth. + seem + like +…；③sb/sth + seem + to (do)；④It seems that + 从句。如：He seemed (to be) very happy when he was called by the headmaster. (被校长叫到名字时他好象很开心) / It seems that nobody else could do such a foolish thing except Jim. (除了吉姆好象没有什么人会做出如此愚蠢的事情来)

(3) be afraid(害怕)的用法：记住几个结构：①be afraid of sth; be afraid of (doing); ②be afraid to (do); ③be afraid that+从句。如：She is a little afraid of snakes.(她有点怕蛇)/ Don’t be so afraid to stay at home alone at night.(别害怕晚上一个人在家)/ I’m afraid that somebody will take his place because of his serious mistakes.(恐怕

有人要取代他了,因为他犯了那么大的错误)

(4) be sorry(抱歉)的用法：记住几个结构：①be sorry for (sth); ②be sorry for (doing sth); ③be sorry to (do); ④be sorry that+从句。如：I am very sorry for keeping you waiting so long.(不好意思让你久等了)I am sorry to trouble you.(对不起,麻烦你了)/ I am sorry (that) he isn’t here at the moment.(恐怕他现在不在)

(6) make 与do的用法：一般情况下表示进行活动或者做工作用do,表示创造建构某事物用make. 如：I don’t know what to do.(我不知道该干什么)/ I’m not going to do any work.(我不准备做什么)/ My father and I once made a boat.(我和我爸曾经做过一只船)

此外还要记住一些固定说法：do good / harm / business / one’s best / a favour……

make a decision / an effort / a mistake / a noise / a phone call / money / war / the bed / sure,...

(7)put on、wear、have…on、be in、try on、dress的用法：put on强调“穿、戴”

这个动作过程,wear则表示“穿着、戴着”这一状态,have+衣物+on主要表示状态,be in(+颜色/衣物)也是表示一个状况,dress(+人)表示“给…人穿衣”。如：Please put on your new shoes.(请穿上你的新鞋)/ The twins are wearing the same clothes.(双胞胎穿着相同的衣服)/ Today she has an overcoat on.(今天她穿着一件大衣) / Do you know the woman who is in black?(你认识那个身穿黑衣的女人吗？)/ Dad is dressing Tom now.(爹正在给汤姆穿衣)

[注意]dress与wear或put on的区别：wear或put on常用衣物作宾语,而dress常用人作宾语。表示给自己穿衣时常用“get dressed”或“dress oneself”表达。be dressed in与wear基本同义。dress up意为“穿上盛装、乔装打扮”。如：Could you dress the baby for me?(你能替我给宝宝穿衣吗？)/ He is eight but can’t dress himself.(他八岁了,还不会穿衣服)/ She was dressed in a red coat.(她穿着一件红上衣)/ Do I have to dress up to go to Jim’s party?(我得穿上好衣服去参加吉姆的聚会吗？)

(8)like、love与enjoy的用法：三个词都含有“喜欢”的意思,但是,like和enjoy后面跟动名词,love 后面一般跟动词不定式。like后面有时跟动词不定式,表示一种习惯或嗜好(往往与具体的时间或地点有关)。enjoy后面还可以加名词、反身代词,表示“享受…乐趣；玩得开心”。如：Do you like shopping?(你喜欢购物吗？)/ He likes to have a swim when he gets home every afternoon.(每天下午放学后他总爱游个泳)/ They love to sing foreign songs.(他们喜爱唱外国歌曲)/ Did you enjoy yourself at the party?(在聚会上你玩得开心吗？)/ He enjoys living in China.(他喜欢在中国生活)

(9)study、learn的用法： study主要表示“学习、研究”,指过程；而learn主要表示“学会”,指结果。表示“学”时可以互换。如：How many subjects do you study?(你学多少门课程？) / Have you learned it yet?(这个你学过了吗？)/ How long have you

studied/learned English?(你学英语多久了？)

learn还可以表示“听说”,如：He learned the musician himself was in town.(他听说音乐家本人就在城里)

(10)think、want、would like的用法：三个词都含有“想”的意思,但think指“思考、考虑”,want指“想要、愿望、企图”,would like指“想要”,think后面一般跟介词短语或从句,want和would like后面跟名词或动词不定式。如：Do you think that China will become a developed country in 40 years? (你认为中国会在40年后成为发达国家吗？)/ I am thinking of the money I once lent to Li Min.((我正在想着以前借给黎敏的钱)/ What do you really want to say?(你到底想干什么？)/ Which of these cakes would you like (to have)?(这些饼子中你想吃哪些？)

(11)look for、search…for、find、find out的用法：前面两个词语表示动作过程,后面两个表示结果,look for指“寻找”不见的或丢失的东西,但还没有找到；search…for…指“为找…而搜寻…”；find指“找到”了东西；find out主要指“查明一个事实真相”。如：Hey, Monkey, what are you looking for in the cupboard?(嘿,猴儿！你在厨子里面找什么呢？)/ Have you found the lost key to your car?(你找着丢失的车钥匙了吗？)/ The soldiers were searching the room for the spy when they heard a loud noise.(士兵们正在房间里面搜寻间谍突然间他们听到了衣声巨响)/ Let’s try to find out who broke the window.(让我们查查谁把窗子打破了)

[注解] find的几个结构：find sb. sth“为某人找到…”,find sth./sb. + adj./n.“发觉某人是…”,find it +adj. + to do…(或+宾语从句)“发现(做……)如何”。如： His mother found her daughter a very clever girl.(他的母亲发现她的女儿是个聪明的女孩)(名词作

补语补足语) / You can easily find it not good for your health to eat cold food.(你很容易就会发现吃冷食对你的身体是不利的)

(12)listen to、hear的用法：两个词与听觉有关,listen to指“听”这一过程,hear指“听到”这一结果。如：Are you listening to me,Jim? Yes,I have heard your words.(吉姆,你在听我说吗？是的,你的话我全听见了)

(13)look、see、watch、read的用法：四个词均与眼睛有关,look指放眼去“看”(不管是否看得到),指“看”的过程；see指“看见”这一结果,有时see还引申为“明白”,表示“看”时后面加“电影”等词；watch指专注的看,含有“注视、监视”之义,后面常跟“电视、比赛”等词；read限制为看书面材料,译为“看、阅读”,后面跟“书、报纸、杂志”等词。如：What are you looking at?(你在看什么？)/ Please look at the blackboard.

(我听说格林先生今晚要来看望我们)/ Have you ever heard of the man who once went to the Himalaya Mountains? (你是否听说过那个去过喜马拉雅山的人？)/ How often do you hear from your father? (隔多久你收到你父亲的信？)/ He learned the musician himself was in town.(他听说音乐家本人就在城里)

(15)speak、talk、say、tell的用法：四个词与“说”有关。speak“讲话、发言、演说”,是不及物动词,涉及人时要加介词to,speak作及物动词时后面跟语言名称；talk“谈话、闲谈”,是不及物动词,涉及人时用介词with、to等,涉及事情时后面跟介词about等；say 是及物动词,后面跟名词、代词、从句等,表示说的内容；tell是及物动词,后面首先要跟人,然后再跟从句或者介词短语等。如：Do you speak English? (你讲英语吗？)/ Who spoke at the meeting? (谁在会上发了言？)/ Our teacher is talking to Lin Tao’s parent. (我们的老师正在跟林涛的家长讲话)/ Can you say it in English? (你能用英语说出它吗？)/ Please tell me something about the strange flying object. (请跟我讲讲那个奇怪的飞行物的事情吧)

(16)be able to(do)、can的用法：can是情态动词,有许多含义,表示“可能、可以、会”等意思,只有现在式can和过去式could两种形式；be able to表示能力上“会”,有多种时态形式,to后面跟动词原形,有时可以与can/could互换。如：Can you speak English? (你会说英语吗？)/ He couldn’t(wasn’t able to) swim when he was 12. (他十二岁时不会游泳)

(17)there be、have的用法：两个词都可以译为“有”,但是,have表示的是“拥有”,主语必须是人或者物；there be表示“存在”的概念,主语在there be之后。如：How many brothers and sisters do you have? I have only one brother. (你有多少兄弟？我只有一个兄弟。)/ How many chairs and desks are there in their classroom? There is none. (他们教室里有多少张桌椅？一张也没有。)

[注解]there be sb./sth doing与there be sb./sth to do 有所不同：用doing表示一个正在发生的事情,而用to do 则表示一个滞后或迟于there be的动作。如： Look! There is a dog lying on the stairway. / Take your time. There is nothing for you to

do tonight.

(18)borrow、lend、keep的用法：表示“借”的三个词,borrow“借进”、lend“出借”都是一次性动作,不可以和表示一段的时间状语连用；keep“保存”用来表示借一段时间。如： I have lost the book I borrowed from my teacher. What can I do? (我丢掉了从老师那里借来的书)/ How long have you kept my dictionary,eh?For more than two months! (呃,我的字典你借了多久了？两个多月了！)

(19)bring、take、carry、send、lift的用法：bring指从远处“拿来”；take指从面前“拿走”；carry指一般的搬运,不涉及方向；send主要指“送、派遣、寄”；lift指把东西由低向高“提起、拎起”。例略。

(20)hope、wish的用法：两个词都表示“希望”,但是,hope表达有把握或信心实现的事情,后面直接跟动词不定式或者宾语从句,不可以跟动名词或作宾语补足语的不定式；wish表达实现的可能性不大的事情,后面跟名词、宾语从句(用过去时)或者作宾语补足语的不定式。如：We all hope to see him very soon. (我们全都希望尽快见到他)/ I hope it will be fine tomorrow so that we can go out. (我希望明天天好,这样我们就能出去了。)/ How I wish it was not raining at the moment!(我多么希望此刻不在下雨！)(事实上天正在下雨)

(21)take、spend、pay、cost的用法：

spend的宾语通常是金钱或时间,句型：sb.+(spend)+时间/金钱+on sth / (in) doing sth. ；

take的主语通常是事情,句型：sth./It + (take)+sb.+时间+to do… 。(如果是动作则常用it作形式主语将动词不定式后移)；

cost的宾语通常是时间、金钱、力气,句型：sth. +(cost)+sb.+时间/金钱/力气. ；

九、连接词

1、连词的含义：连接词与词、短语与短语、或引导从句的词叫连接词。

2、连词的分类：连词分为并列连接词和从属连接词两种。

1、并列连接词连接并列的词、短语、从句或句子。常见的并列连接词有：and(和),but(但是),or(或者,否则),nor(也不), so(所以), however(然而,无论如何),for(因为),still(可是),as

well as(也),both..and...(...和...), not only ...but also...(不但…而且…), either… or…(或…或…),neither… nor…(既不…也不…)等。

2、从属连接词用于引导从句,常见的从属连接词有：

when(当…时候), while(正当…时候), after(在…之后), before(在…之前), since(自从), until(直到), although/though(虽然), if(假如), as(如…一样；由于), as …as…(和…一样), as far as(就…而言), as long as(只要), as soon as(一…就…), even if(即使), because(因为), unless (除非), than(比…), whether (是否…), in order that…(为了), so…that…(如此…以致), so that…(以便), now that…(现在既然), by the time…(到…时候), every time…(每当), as if…(仿佛),no matter when(或whenever)(无论何时),no matter where(或wherever)(无论在哪里)等。

［辨析］

(1) because、as、since、for的用法：because(因为)表示原因的语气最强,常表示必然的因果关系,从句一般放在主句后面；另外,回答why的问句只能用because. as(因为)表示一般的因果关系,语气比because弱,说明比较明显的原因,它引导的从句可以放在句首也可以放在句尾。since(既然)表示对方已经知道、无需加以说明的原因或事实。for(因为)是并列连词,语气较弱,用来补充说明理由或提供一种解释。如：He is not at school today because he is seriously ill.（他今天没有上学因为他病得厉害）/ As all of you have got here, now, let’s go to the zoo.（既然大伙儿都到了我们就去动物园吧）/ I will ask Lin Tao to go with me since you are very busy.（既然你很忙我就叫林涛和我一起去吧）/ We must be off now for the match starts at 7：00.（我们得走了因为比赛在七点开始）

(2)if、whether的区别：表示“是否”时,if和whether同义,引导宾语从句,另外,whether还可以引导主语从句、表语从句(以及同位语从句)等名词性从句或者让步状语从句；而if还可以表示“如果”,引导条件状语从句,(主句与从句遵循主将从现的原则)。如：I don’t know if/whether he will arrive on time.（我不知道他是不是会按时到达）/ I will ring you up if he arrives on time.（如果他按时到达我会给你打电话的）

[注意]下列情况只能用whether不能用if：①引导主语从句,②引导表语从句,③引导从句作介词宾语,④引导不定式短语,⑤引导让步状语从句,⑥在动词discuss之后,⑦在wonder / not sure之后,⑧在if与whether含义易混时。如：Whether it is a fine day next Sunday is still a question.（下个星期天是不是个好天还是个问题）(引导主语从句) / Please ask him whether to go there with a raincoat or not.（请问一下带不带雨衣去那儿）(作动词的宾语) / Hainan is the place to be, whether it’s summer or winter.（海南是个该去的地方无论冬夏）(引导让步状语从句)/ Please let me know whether you need my help.（请告诉我你是否需要我的帮助）(引导宾语从句)(如果换成if则还可能表示“如果你需要我的帮助请告知”)

(3)while、when、as的用法区别：while常表示一个较长的动作,它引导的从句动作与主句的动作是同时发生的、是平行的；when可以表示较短的动作也可以表示较长的动作,主句和从句的动作可以同时发生也可以先后发生；as与上两词同义,可替换while和when, 表示主句和从句的动作同时发生,常译为“一边……一边……”。如：Please do not trouble me while I am writing my homework.（我写作业时请不要打扰我）/ I’ll go home when I have finished my job.（我干完了活儿就回去）/ They were running quickly across the road when they heard the sound of a truck coming.（他们正快速地穿过马路忽然听到了卡车开来的声音）/ As we walked in the dark street, we sang songs and talked loudly.（当我们在黑洞洞的街上走路时我们高声地唱歌说话）

(4)till/until与not…till/until的区别：前者表示一个延续性的动作,后者表示一个才开始的动作。如：I will stay here and watch the baby until you return.（我会呆在这里看着娃娃直到你回来）(stay这个动作一直进行到你return) / They won’t go on working until they get what they think is reasonable.（他们要到获得了他们认为合理的东西时才会继续干下去的）

另外till与until基本可以互换,但是在句首时只能用until,不能用till. 如：Until the last minute of the match we kept playing.（我们坚持到比赛的最后一分钟）/ Not until he had finished his work did he go home.（直到做完工作他才回家）（倒装句）

(5)though与although的区别：两个词都表示“虽然”,均不可以与but同时使用,但在句中可加still或yet连用。although“尽管、虽然”仅作连词,比较正式,一般可以换为though； though“虽然、尽管、即使”,还可以与even连用(=even if),表示“即使、纵然”,作副词时意思是“然而、不过”,不能放在句首。如：He passed the exams although illness prevented him from going to classes.（尽管疾病使他无法上课但是他还是通过了考试）/ she won’t leave the TV set,even though her husband is waiting for her for the supper.（她不愿离开电视机虽然丈夫在等她吃饭）/ It was a quiet party. I had a good time, though.（这是个不热闹的聚会尽管如此我还是玩得很开心）

(6)prefer to…rather than…与prefer…to…的区别：prefer to…rather than…后面都是用动词原形,prefer…to…都是用动名词或名词。如：I prefer English to Japanese.（与日语相比我更喜欢英语）/ I prefer to learn English rather than learn Japanese. （与日语相比我更喜欢学英语）

十、简单句

1、简单句的特点：简单句通常只由一个主语(或并列主语)和一个谓语(或并列谓语)构成。

2、简单句的种类：简单句一般分为陈述句、疑问句、感叹句和祈使句四种。

3、陈述句：

用来说明一个事实的句子叫陈述句。它有肯定式和否定式两种形式。

▲陈述句的肯定式： He is a middle school student.（他是个中学生）/ I have a hammer in my hand.（我手上有把锤子）/ She teaches us geography.（她教我们地理）/ The new play was good enough and everybody enjoyed it.（新的话剧非常好大家都喜欢）

▲陈述句的否定式：

1)谓语动词如果是to be 、助动词、情态动词时,在它们的后面加“not”。如：My brother is not a teacher.（我的弟弟不是教师）/ He does not have a cousin.（他没有堂兄弟）/ I will not go there tomorrow.（明天我不去那儿）/ My mother is not cooking a meal in the kitchen.（我母亲现在不在厨房里做饭）/ You must not make such mistakes again.（你不该再犯类似错误了） / We haven’t discussed the question yet（我们还没有讨论那个问题呢）.

2)谓语动词如果没有上述词语而是其他动词时,须在它的前面加do not(don’t).如： I don’t know anything about it.(此事我一无所知) / Li Ming does not feed pigs in the

countryside.（李明不在农村养猪）/ We didn’t expect to meet her right here.（我们没指望着在这里见到她）/ We didn’t have a meeting yesterday afternoon.(昨天下午我们没有开会)

3)如果“have”作“有”讲,也可以在它后面加not构成否定式,其形式与have got的否定式相同。 如：I haven’t (got) any brothers or sisters.（我没有兄弟姐妹）

[注意]

①句子中如果有all、both、very much/well等词时,用not一般构成部分否定,如果要完全否定,则通常使用none、neither、not…at all等；All of them went there.→None of them went there.（他们全都去了那里→他们全都没去那里）

②句子中含有little、few、too(太)、hardly、never、neither、nor、seldom等词时, 则视为否定句。如：Few people live there because life there is very hard.（几乎没有人生活在那里因为那里的生活太艰难了）

③陈述句(主语+谓语+其他)在口语中可以直接表示疑问,表示惊讶或明知故问。如：That’s your boss?（那就是你的老板？！）

④陈述句一般情况下应使用正常的语序,即：主语+谓语+其他。但是有时会倒装,详见“倒装句”。

⑤所有的从句一律使用陈述句语序,即在连接词后采用“主语+谓语+其他”的顺序。如：The old man told me that he would live here for ten more years before he

returns home. （老人告诉我说他还要在这儿住几年然后回家）/ Could you tell me who you saw at the party last night?（能告诉我在聚会上你都看见了谁吗？）

4、疑问句：

▲一般疑问句： 用“yes”或“no”来回答的疑问句叫做一般疑问句。

1)一般疑问句构成：句中谓语动词是to be、助动词、情态动词时,则将它们(提前)放到主语前面。如：Is he an engineer?（他是工程师吗？）/ Have you got today’s newspaper? （你有今天的报纸吗？）/ Shall we go to see a film this evening? （我们今晚去看电影好吗？）/ Can you explain it ?（你能解释它吗？）/ Is there any fish for supper?（晚饭有鱼吗？）/ Would you like to go out for a walk?（你想出去散步吗？）

谓语动词如果没有上述词语而是其他动词时,则在主语前面加助动词do / does / did, 原来的谓语动词改为原形。如：Do you get up at six every morning?（你天天早晨六点起身吗？）/ Does she study hard?（她学习努力吗？）/ Did you go there yesterday?（昨天你去那儿了吗？）

2)一般疑问句的回答：

一般疑问句通常用简略形式来回答。如：

Will you join us in playing basketball?（你加入我们打篮球好吗？）—Yes, we will.（是的我们会。）/ —No, we won’t.（不我们不会。）

Have you got today’s newspaper?（你有今天的报纸吗？）—Yes, I have .（是的

有。）/ —No, I haven’t.（不没有。）

回答时所用的时态应和问句里的时态一致。

[注意] 回答must或者may开头的疑问句要小心,参见情态动词有关内容。

3)一般疑问句的否定结构(即否定形式的一般疑问句)表示惊奇、责怪、建议、看法等,只要将“not”置于主语之后或者将“not”放到主语之前与be, have等助动词或情态动词合并在一起就可以了。如：

Will he not come?（他难道不来吗？）/ Isn’t your sister a Party member?（你的姐姐不是党员吗？）/ Haven’t you any brothers?（你没有哥哥吗？）/ Don’t you like the play?（你难道不喜欢这个话剧吗？）/ Can’t we walk a little farther?（我们不能走远些吗？）/ Won’t you sit down?（你不想坐下吗？）/ Hasn’t she heard of the matter?（她没听说过这事儿？）

这种否定结构的疑问句的回答与汉语的习惯不同。如果回答是肯定的,就用“yes+肯定结构”；如果回答是否定的,就用“no+否定结构”。(情况与反意问句类似。)如：

Can’t he answer the question? (他不能回答这个问题吗？)

—Yes,he can.(不,他能回答这个问题。) —No,he can’t. (是的,他不能回答这个问题。)

▲特殊疑问句：要求具体回答的问句。

1)特殊疑问句结构是：

疑问代词 +一般疑问句+？

除who以外的疑问代词短语

疑问副词

如：What do you want?（你要什么？）/ Who(m) are you looking for ?（你在找谁？）/ Whose magazine is this?（这是谁的杂志？）/Which class are you in?（你在哪班？）/ When did you get up this morning?（你今早什么时候起身的？）/ Where have you been?（你到哪儿去了？）/ Why did he go to bed so early?（他为什么这么早睡觉？）/ How did you go there?（你是怎么去的那儿？）

但是,“who”引出的询问主语或主语部分相关词的特殊疑问句的结构与陈述句词序相同：如：Who is dancing over there?（谁在那边跳舞？）

有时“what”,“which”,“whose”也可以引出与陈述句词序相同的特殊疑问句。如：What is on the wall?（什么东西在墙上？/墙上有什么？）/ Which is yours?（哪个是你的？）/ Whose book is in your bag?（谁的书在你的书包里？）

[注意]从陈述句改为特殊问句时,先将句子改为一般问句,再将(划线)提问部分更改为疑问词置于句首,特别要注意助动词的使用！如果只对主语或主语的修饰词提问,那么只需要将疑问部分改为疑问词即可。

2)常用疑问代词和疑问副词：

疑问代词： who, whom, whose, which, what,

疑问副词： when, where, why, how,

how构成的短语：how many (多少个) (独立用；或跟可数名词), how much (多少) (独立用；或跟不可数名词), how old (多大年纪), how far (多远), how often (多常),how long (多久,多长), how soon (多久以后),how many times (多少次),等等。

3)特殊疑问句有时也用否定式。如：Why don’t you ask Jim instead?(常缩略为Why not…?) (你为什么不转请Jim呢？)

4) 特殊疑问句疑问部分有时可以有两个以上的疑问词。如：When and where were you born? (你是何时何地出生的？)

5) 疑问词如果是介词的宾语,则该介词可以在句首,也可以在句尾。如：What do you want a computer for? = For what do you want a computer? (你干嘛要一台电脑呢？)

▲反意疑问句： 反意疑问句表示对陈述句所说的事实提出相反的疑问,要求对方用“yes”或“no”来进行回答。

1) 构成：由两部分组成：前一部分是陈述句,后一部分是疑问句,它是由be ,have, 助动词或情态动词+主语构成。如果陈述句是肯定结构,反意疑问句须用否定结构；反之,陈述句如果是否定结构,反意疑问句须用肯定结构。反意疑问句的两部分,必须保持人称和时态的一致；反意疑问句的回答有时会和汉语不同。

陈述句部分 附加问句部分 注 意 点

肯定陈述句 否定的简短一般问句 当陈述句部分含有“是”动词、(“有”动词)、情态动词和助动词时,简短问句中沿用该词；否则就使用do/does//did.

否定陈述句 肯定的简短一般问句

如：He is old, isn’t he? (他老了不是吗？) / The man went away, didn’t he? (那个男人走开了不是吗？) / He isn’t old, is he? (他不老是吗？) / He never went there, did he? (他从没有去过那里是吗？)

2) 反意问句的回答：

无论哪种形式的反意问句,回答时要遵循：“Yes,+肯定式”或者“No,+否定式”

如：The man went away, didn’t he?(那人走开了,不是吗？)

——Yes, he did.(是的,他走了。)/ No, he didn’t.(不,他没有走。)

The man never went there, did he?(这人从来不去那里,是吗？)

——Yes, he did.(不是呀,他去的。)/ No, he didn’t.(是呀,他不去。)

▲选择疑问句：提出两种或两种以上情况,需要对方作出选择回答的疑问句叫选择疑问句。

1) 构成：(1) 一般疑问句 + or + 第二选项？

(2) 特殊疑问句 + 第一选项(+ 第二选项)+ or + 第三选项？

2)选择疑问句的结构与特殊疑问句相同,即要具体回答,不可以用yes / no回答。如：

Is your friend a boy or a girl? –A girl. (----你的朋友是男孩还是女孩？----是女孩。) / Which do you prefer, coffee or tea? –Tea, please. (---你要哪一样咖啡还是茶？----请来茶吧。) / Which do you like best, singing, dancing or skating? --Dancing, of course. (----唱歌、跳舞和溜冰你最喜欢哪样？----当然是跳舞啦！)

5、祈使句：祈使句用来表示请求、命令等。它的主语you往往不说出。

▲祈使句的肯定式： 动词(原形) + 其他 如：Please give me a hand. (请帮忙) / Shut up! (住嘴！)

▲祈使句的否定式： Don’t +动词原形 + 其他 如：Please don’t talk in low voices. (请不要低声讲话。) / Don’t look back! (不要掉头看。)

[注意] 以“let’s”引出的祈使句的否定结构,“not”应放在“let’s”后面。如：Let’s not trouble him. (我们不要打扰他。)

肯定祈使句前可以用助动词来强调语气。如：Please do help me! (请千万帮帮我。)

6、感叹句：感叹句用来表示喜怒哀乐等强烈感情。句末常用“！”

▲对含有形容词的名词短语感叹的结构通常是：

What + (a /an) + (形容词) +名词+ 陈述句结构(主谓语) ,用来强调句子中的名词,如：What a good, kind girl (she is)! (她是多么善良的好女孩！) / What bad weather (it is)! (天气真糟糕！)

▲仅对形容词或副词进行感叹的结构通常是：How + 形容词/副词 + 陈述句结构(主谓语) ,用来强调句子中的形容词、副词或动词。How carefully the old man walks! (这老人走路真小心！) / How delicious the food is! (这食品真好吃！) / How beautiful! (真美呀！)

▲有时,陈述句、祈使句、疑问句、一个词或词组,也带有一定的感情色彩,也可以成为感叹句,此时未必使用感叹句型。He is sitting on a tiger’s back! (他坐在老虎的背上！) / A nice shot! (漂亮一击！) / Good goal! (好球！)

十一、句子成分：主语、谓语、宾语、表语、定语、宾语补足语和状语

1、主语：

(1)由名词、代词(人称代词用主格)、动词不定式、动名词等充当,说明动作是“谁”发出的。如：The painter painted a very nice picture. (画家画了一幅漂亮的画。) / They fought against SARS bravely. (他们勇敢地与非典搏斗。) / To see is to believe. (耳听为虚眼见为实). / Helping animals is to help people. (帮助动物就是帮助人类。)

(2)动词不定式或动名词做主语时可用it代替,而不定式或动名词移至表语或宾语之后。如：It is very comfortable to have a Class A seat during the long journey. (在长途旅行中能有个甲等座位简直太舒服了。) / Eating too much is bad for your health.(=It is

bad for your health eating too much.) (吃得太多对你的身体不利。)

(3)口语中常见主语或“主--系”省略：(It is) nothing. ((那)没有什么。)/ (It) doesn’t matter. ((那)没有关系。) / (I) thank you. ((我)谢谢你。)

(4)反意问句的附加问句,主语必须是代词：The man looks worried,doesn’t he? (这个人看上去很着急不是吗？) / Tigers are dangerous animals, aren’t they? (老虎是危险的动物不是吗？)

(5)祈使句一般省略主语。加主语时往往用来指定某个人。Keep the keyboards clean, children. (孩子们请保持键盘的清洁。) (省略了主语) / You go there and fetch me a glass of water. (你去给我弄一杯水来。)

(6)主语一般在句首,但在问句中会处于第二位和句尾；倒装句及there be句型主语在动词之后。如：Computers are made in this factory. (计算机生产于这家工厂。) / Where are they? (他们在哪儿？) / Does the boy like staying home? (这个男孩喜欢呆在家里吗？)

(7)主语与谓语必须保持单、复数的一致, 而谓语与表语或宾语之间没有这一要求。Neither Jim nor Rose has passed the exam. (Jim和Rose都没有通过考试。) / The Chinese people are a hardworking and brave people. (中华民族是一个勤劳勇敢的民族。)

(8)主语可以由从句充当,详见“主语从句”。

2、谓语：

(1)由“不及物动词”、“及物动词+宾语”或“系动词+表语”等构成,说明主语所表示的人物“干什么”或“怎么样”。如：

He travelled in space for the first time.(他首次在太空旅行。) / Who teaches you English this year?(今年谁教你们的英语？) / The pizza has gone bad. (那块烤馅饼已经变坏。) /

(2)谓语动词必须反映出人称、单复数、时态等信息,谓语动词往往由下列词语依序排列构成：［情态动词］+［时态助动词］+［语态助动词］+［主要动词］(不一定全部出现)。(见动词的时态和语态构成表) 记住：谓语部分第一个动词往往是变形动词。如：

I am sorry I am making so much noise but I have to. (对不起我发出了太大的声音但是只能这样。) / He can’t have finished reading the 800-page-long novel. (他不可能读完了那本长达800页的小说。) / Something must be done to stop the fowl flu from spreading out. (该采取措施防止

禽流感蔓延。)

(3)谓语动词切忌用“行为动词1 + 原形动词”、“be + 原形动词”。

记住使用下列正确形式：

①情态动词+原形动词。如：You’d better go over the lesson.（你最好复习这一课。）

②shall/ will/ would+原形动词。如：They should have been there once.（他们应该去过那儿。）

③be+现在分词或者过去分词。如：What are you doing this evening?（今晚你打算做什么？）/ Many trees have been cut down since 1970s.（自从20世纪70年代大批树木被砍伐。）

④have+过去分词。如：Many trees have been cut down since 1970s.（意思同上）

⑤一般时问句和否定句中：do/does/did+原形动词。如：He does not enjoy himself very much.（他日子过的不好。）/ Did any of you see dinosaur eggs?（你们当中有谁见过恐龙蛋吗？）

⑥行为动词1+行为动词2 (不定式、动名词、现在分词、过去分词等形式)。如：He made up his mind to be a vet.（他拿定主意要做个兽医。）/ Feeling good about yourself is essential to feeling good about life.（自尊自爱是享受生活的根本。）/ They wake up the other family members, calling,“Merry Christmas!”（他们叫醒家庭的其他成员,呼喊着：圣诞快乐！）/ The kings of ancient Egypt had strong tombs built for themselves.（古代的埃及国王让人给他们自己修建坚固的坟墓。）

(4)不可用形容词、名词、代词、副词、介词短语等独立作谓语,必须在此之前加连系动词。

(5)谓语动词单复数形式：单数形式的动词有：is,was,has,does以及“动词+s”；复数形式的动词有：are,were,have以及动词原形。其他动词不分单、复数。

谓语部分第一个动词的形式 单数形式 复数形式

一般现在时be(是)动词；

现在某些时态和语态的助动词be am (单一); are (单二); is (单三); are

其他各时态语态的谓语动词 单复数形式相同

记住：主语、谓语单复数必须保持一致。（参见“4、名词或代词作主语时和谓语之间的单复数的一致问题：”） Air and water is necessary to us all.(空气和水对于我们大家是必不可少的。)

(6)一般问句和反意问句的回答不使用行为动词,应该使用“是”动词、情态动词、助动

词(be,will,have,do以及变形)。如：The Olympic Games is held every other year, isn’t it? ----Yes, it is.(奥运会每两年举办一次,是吗？----是的。)

3、宾语：

(1) 由名词、代词(人称代词要用宾格)、不定式、动名词、(宾语)从句充当,表示动作的承受者是“谁”或者是“何物”。如： The angel also came to Joseph and told him the same thing.(那个天使同样来到约瑟夫面前并且告诉他同样的事情。)(代词和名词充当两个宾语) / He told me that the company could not afford to pay him so much money.(他告诉我说公司付不起他那么多的钱。)(不定式作宾语) / They enjoy watching football games so much that they often forget their lessons.(他们如此喜爱看足球以至于常常忘记了他们的功课。)(动名词作宾语) / I think to be a children’s doctor is very rewarding.(我认为当个儿童医生是很值得的。)(从句作宾语)

(2) 只有及物动词或介词才有宾语,不及物动词没有宾语,如果涉及到事物,则必须在不及物动词后面加合适的介词。Listen to the radio. (listen不是及物动词,故加to。) / Can you hear anything exciting?(你能听到什么令人兴奋的消息吗？)

(3) 宾语一般放在及物动词或介词的后面,但是在疑问句中,如果宾语是疑问词,则宾语要放在句首。介词的宾语如果是疑问词,则可以放在介词后或句首。如：What did he see? (他看见了什么？) / What does he write a letter with? (他用什么写的信？) / With what does he write a letter? (他用什么写的信？)

(4)“动词+副词+宾语”结构中,如果宾语是代词,则代词必须放在“动”“副”之间。如：Please put the shoes away. (请把鞋子收起来。) / Please put away the shoes. (请

把鞋子收起来。) / Please put them away. (请把它们收起来。)

(5) 动词后面跟双宾语时可以采用两种结构：

①动词+间接宾语(人)+直接宾语(物)。如：He often gives me some help. (他常常帮我。)

②动词+直接宾语+介词+间接宾语。注意,一般情况介词用to,但动词是make, buy, borrow时,介词用for.如： Please make me a kite. (请给我做个风筝。)或Please make a kite for me.

(6) 在“动词+宾语+宾补”结构中,如果宾语是不定式、动名词、宾语从句,则常用it做形式宾语,而将实际的宾语移到补语后面去。如：I found the job rather difficult. (我发觉这个工作相当难做。) / I found it rather difficult to do the job.

(7) 宾语可以由从句充当,详见“宾语从句”。

4、表语：

(1) 说明主语的身份、性质、状况等含义的成分,通常由形容词、副词、介词短语、名词、代词等充当。如：He became a doctor after he left high school.(高中毕业他当上了医生。) / The rubber wheels are over there.(橡胶轮子在那边。) / He does not feel like eating anything today because he has caught a bad cold.(他今天不想吃任何东西因为他得了重感冒。) / Who is it?(谁呀？)

(2) 表语只能放在连系动词(如：be,look,become,turn get,grow,feel,seem) 之后,

对表语进行提问的句子除外。

(3) 代词做表语一般用主格,口语中常用宾。如：It’s I. (It’s me.)是我。

(4) 只能作表语的形容词有：

sorry,afraid,alone,asleep,awake,ill,well,sure,interested等等。He was terribly sorry for his carelessness.(他很为他的粗心而歉疚。) / Please make no noise here; the baby is asleep.(请不要发出响动,婴儿正熟睡呢。) / I am only interested in sitting in a boat and doing nothing at all!(我只是对独坐孤舟无所事事感兴趣。) / I am not alone in thinking so.(并非只有我才这样想的。)

(5) 表语也可以由从句充当,详见“表语从句”。

5、定语：

(1) 修饰名词或代词的成分,常由形容词、名词(含所有格)、代词(物主、指示、疑问、不定)、介词短语、不定式(短语)充当,在初三阶段还学习了定语从句做定语的知识。如：Put it in the top drawer.(把它放在最上层的抽屉里。) / France and Switzerland are European countries. (法国和瑞士是欧洲国家。) / His mother and father are both college teachers.(他的父母都是大学教师。) / This is the day that I can never forget in my life.(这是我一辈子难忘的日子。)

(2) 单词做定语时一般放在被修饰的名词前面,而且有一定的次序：

(3) 时间副词(now,then,today,yesterday,...)、地点副词

(here,there,back,in,out,home,...作定语时放在被修饰的名词后面。如：I could not find my way out, so I stayed there all along. (我找不到出去的路,所以就一直呆在那儿。)

(4) 介词短语修饰名词时只能放在名词的后面：The monkey in the cage was caught yesterday. (笼子里的猴子是昨天逮着的。)

(5) 形容词修饰复合不定代词时,往往后置。如：He remembered everything unusual. (他记得所有不寻常的事情。)

(6) 定语还可以用从句充当,详见 定语从句。

(7) 注意：由于定语属于修饰性的成分,因此它常归入主语、宾语、表语之中,不作为句子的主要成分。

6、状语：

(1) 说明动作“何时”、“何地”、“如何”发生,或者说明形容词或副词的程度,一般由副词、介词短语、不定式、状语从句等充当。如：I was not born yesterday.（我又不是昨天才出世的娃娃。）/ For many of these families a college education was something new.（对其中的许多家庭来说,大学教育是件新事物。）/ He woke up to find his house on fire.(他醒来发现房子着火了。) / You cannot leave until your work is finished.(在你的工作被完成以前你不能离开)

(2) 副词作状语位置较为灵活,详见《六?2》“副词在句子中的位置以及作用”；介词短语作状语,位置基本固定,详见《七?4》“介词短语在句子中的位置”；不定式作状语,一般表

示目的、结果,详见《八?7》“动词的非谓语形式”；从句作状语,详见《主从复合句》的“状语从句”。

(3) 多个状语相连时,一般先单词、后短语,先地点、后时间,先小概念、后大概念。如：He went ouf of the room at a quarter to 23:00 last night and then disappeared into the dark.(他昨夜22点3刻从房间里出来,然后消失在黑暗之中。) /

(4) 状语还可以用从句来充当,有时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、比较状语从句、让步状语从句、条件状语从句等。详见“状语从句”。

(5) 注意：由于状语属于修饰性的成分,常归入谓语,因此不作为句子的主要成分。

7、宾语补足语：

(1) 补充说明宾语的动作、状态的成分为宾语补足语,常由名词、形容词、动词非谓语形式(不定式、现在分词、过去分词等)、介词短语等充当。如：Call him Jim, please. (请叫他Jim。) / I tried my best to make him happy. (我竭尽所能让他开心。) / Ask her to come to dinner tomorrow. (请他明天来。) / He let the smaller animals bring food to him. (他让小动物们给他带食物来。)

(2) 部分表示位置、方向的副词也可以作宾语补足语。如：Let him in, I tell you! (我跟你说,让他进来！)/ Please put it away. (请把它收起来。)

(3) 不定式或分词作宾语补足语的情况,详见《八?7》“动词的非谓语形式”相关内容。

十二、简单句五种基本句型：

句子包含主要句子成分(主语、谓语)和次要句子成分(表语、宾语、宾语补足语),按照动词的性质将英语简单句划分为以下五种基本句型：

1、基本句型的词序： 2、划分符号(没有统一规定,仅供参考)：

3、例句：Jim is working [very hard] [now].（他现在正非常努力地工作。）

She is young. It looks like rain.

The boy [always] kicked the dog [with his feet]. （这男孩老是用脚踢那只狗。）

He has [never] bought me a toy [since last year]. （从去年起他没给我买过一个玩具。）

He felt something (cold) .（他感到有个冰冷的东西顺着腿上爬。）

十三、并列复合句

1、基本概念：

并列复合句是由两个或两个以上并列而又独立的简单句构成。两个简单句常由并列连接词连在一起；但有时不用连接词,只在两个简单句之间用一逗号或分号。

2、常见的并列句：

(1) 用来连接两个并列概念的连接词有and , not only…but also…, neither…nor…等,and所连接的前后分句往往表示先后关系、递进关系。前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。

(2) 表示在两者之间选择一个, 常用的连接词有or,otherwise,or else,either…or…等,前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。

(3) 表明两个概念彼此有矛盾、相反或者转折, 常用的连接词有but,yet,still ,however等,前后分句时态一致。

(4) 说明原因, 用连接词for ,前后分句时态一致。

(5) 表示结果,用连接词so, 前后分句时态一致。

十四、主从复合句

1、概念：

主从复合句由一个主句和一个或一个以上的从句构成。主句为句子的主体,从句只用作句子的一个次要成分,不能独立成为一个句子。从句通常由关联词引导,并由关联词将从句和主句联系在一起。如：While the grandparents love the children, they are strict with them.(爷爷奶奶们很爱孩子,同时对他们也严格要求。) / It seemed as if the meeting would never end.(看起来会议没完没了。) / Hurry up, or (else) you'll be late.(快点, 要不然就来不及了。) / However I cook eggs, the child still refuses to eat them.(不管我

用什么方法煮鸡蛋,小孩还是不肯吃。)

2、分类：

从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。（参见以下各条）

3、各从句在句子中的位置以及用法：

(1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。

例如：That is why he did not come to school yesterday. / It is because you are so clever.

(2) 宾语从句：在句子中作及物动词或介词的宾语。

①基本形式：（主句＋）连词+从句主语+从句谓语+...

② 关于宾语从句连词的选择：

若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;

若从句来源于一个一般疑问句,连词则用if 或whether;

若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)

例如：They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine. (他问我在哪儿能搞到那样的药。) (从句来源于特殊问句Where can he get such medicine? )

③ 宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时；

如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如：I think I will do better in English this term. (我想本学期我的英语会学得好点。) / The teacher asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。)

④ 下列结构后面的从句一般也作为宾语从句看待：

be sorry / afraid / sure / glad +that从句,如：I’m sorry I’m late. (对不起,我迟到了。) / I’m afraid he isn’t in at the moment. (恐怕他此刻不在家。)

(3) 状语从句：在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原因、目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。

时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever 等引导。时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。如： When you finish the work, you may

go out to play with Sam. (你完成工作就可以出去和Jim一起玩了。) / I won’t leave until Mum comes back. (妈妈回来了我才会走。)

地点状语从句通常由 where, wherever等引导。如：Go back where you came from! (哪里来还滚到哪里去！) / I will never forget to catch the thief who stole my necklace wherever he may be. (我永远也不会忘记去抓住那个偷我项链的贼,无论他会在哪里。)

原因状语从句通常由because, since, as等引导,一般放在句首或句尾。如：He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。)

目的状语从句通常由so that..., so...hat..., in order that... 等引导,往往放在句尾,从句中通常含有can / could / may / might等情态动词。如：He got up earlier so that he could catch the first train. (他起身更早为的是赶上第一班车。)

结果状语从句通常由 so that..., so...that... 等引导,放在句尾。结果状语从句一般表示已经发生的事情,故多为过去时态。如：He lost so many bikes that he decided never to buy a new one. (他丢了那么多辆自行车,他决定再也不买新车了。)

比较状语从句通常由as, than, as (so)...as等引导,一般省略从句的谓语部分,只剩下名词或代词(用主格或宾格均可)。如：Jane is much taller than I/me. (Jane比我高多了。) / I don’t have as many books as you (do). (我书没有你多)

让步状语从句通常由though (although), as, even if( even though), however, whatever等引导。如：Even if you pay the debt(债务) for me, I will not thank you

because it has nothing to do with me. (即使你替我还了债我也不会感谢你,因为它与我毫无关系。) / He wears a T-shirt though it is very cold. (他穿了一件T恤衫,尽管天很冷。)

条件状语从句通常由if, unless, as long as等引导,条件状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。You will certainly fail in the coming final exams unless you work much harder. (即将来到的期末考试你肯定考不及格,除非你更用功。) / If it doesn’ t rain tomorrow, we shall go hiking. (如果明天不下雨我们就要去徒步旅行。)

[注意] 1、because与so；(al)though与but；if与so不可以同在一个句子中成对出现。

2、时间、条件、原因,让步状语从句放在句首时需要用逗号与主句隔开。

(4) 定语从句：在复合句中作定语用修饰句子中某一名词或代词的从句叫定语从句。

① 定语从句的位置：放在名词或代词的后面。如：The man who has an umbrella in his hand is my uncle. (手上抓了一把雨伞的人是我的叔叔。)

② 语法术语的改变：被修饰的名词或代词称为先行词；引导定语从句的连接词称为关系词,其中that、which、who称为关系代词,where、when、how称为关系副词。

③ 关系代词或关系副词的作用：

关系代词who、whom 和whose指人,分别在从句中作主语、宾语和定语。which

指物that多指物, 有时也指人,它们在从句中可以作主语或宾语。定语从句中关系代词作从句宾语时可以省略。This is the thief (that/who/whom) we have been looking for these days. (这个就是我们近日一直在找的小偷。) / Please find a room which is big enough for all of us to live in. (请找一间足够大能住下我们全体的房间。)

关系副词when或where引导定语从句时,它们在从句中分别作时间状语和地点状语。如：This is the room where they had a quarrel a week ago. (这是一个星期前他们吵架的房间。) / I can never forget the day when I first saw you. (我永远不会忘记第一次见到你的日子。)

④ 限制性定语从句和非限制性定语从句。限制性定语从句在句中不能省略,否则主句意思就不完整。非限制性定语从句和主句之间往往用逗号分开,这种从句是一种附加说明,如果从句子中省去,也不致于影响主句的意思。如：She spent the whole evening talking about her latest book, which none of us had heard of. (她一个晚上都在谈论她最近的书,我们一个人都没有听说过那本书。)

[注解]

1、关系代词只能用that的情况：当先行词是指事物的不定代词(all, anything等),或先行词部分含有最高级,或含有序数词时,不能用其他的关系代词,只能用that. 如：All that Lily told me seems untrue. (Lily告诉我的话似乎不真实。) / Can you give me anything that has no sugar inside? (能不能给我点里面没有糖的东西？) / This is the first two-story bus that runs in our city. (这是第一辆运行于我市的双层公交车。)

2、关系代词在从句中作主语时一般用who(指人)、that(指物),而不用that指人或用

which指物。 如：Do you know the woman who is weeping in the corner? (你认识那个在角落里哭泣的女人吗？) / Do not tell me any words that have nothing to do with me. (跟我无关的话,请一个字也不要说。)

3、关系代词作从句的宾语时,常用which或whom,较少使用that或who,而且,关系代词常常省略。如：Tom’s father was the first parent whom our teacher talked to. (Tom的父亲是我们老师第一个谈话的人。)

4、当关系代词紧跟在介词后面时,必须用which或whom,而当介词移到句尾时,则又可以使用that或who. 如：This is the room in which Miss Li once lived. (= This is the room Miss Li once lived in.) (这是李小姐曾经居住过的房间。)

(5) 主语从句：在句子中充当句子主语的从句叫主语从句。位于谓语动词之前。通常由that,whether以及疑问连词引导。一般情况下,常用it替代主语从句,而将主语从句移到句尾。如：When we should start is still a question. (我们该在什么时候开始还是个问题呢。)

十五、直接引语和间接引语(初中不作特别要求)

1、直接引语和间接引语：在陈述句中,直接引用说话人原来的语句,称为直接引语。在书写时,直接引语用引号。用自己的词语来转述表达原来说话人说的内容,称为间接引语。

2、直接引语改变为间接引语：

1、直接引语如果是陈述句,变为间接引语时应注意以下各点：

①不用引号,而用连接词that,但有时可省略。

②人称作相应变化；

③主句里的动词如果是过去时,间接引语中的时态一般应作相应改变： 一般现在时变一般过去时；一般将来时变过去将来时；现在进行时变过去进行时；现在完成时变成过去完成时；一般过去时变成过去完成时；但一般过去时如与一个具体的过去时间连用,则时态不变。

如：He says,\"I am not from the USA.”→He says that he is not from the USA.

Mr Smith said to his girl friend,“ I haven’ t seen you for a long time.”

→Mr Smith said to his girl friend that he had not seen her for a long time.

2、直接引语如果是一般疑问句,变为间接引语时,需用从属连接词whether或if引导,词序要改变。如：Lin Tao said to Miss Green, \"Is it made in China?” →Lin Tao asked Miss Green if it was made in China.

3、直接引语如果是特殊疑问句,变为间接引语时,需用疑问词引导,词序是：连词+主语+谓语。

如：Lucy said to me, “How can I help?” →Lucy asked me how she could help.

4、直接引语如是祈使句,变间接引语时,须将祈使句变为动词不定式,并在动词不定式前用tell, ask, order. 如：He said to the little boy,“ Come here, young man! ”

→He asked the little boy to go there.

5、直接引语变为间接引语时,指示代词以及表示时间和地点的词或词组应作相应变化：

十六、倒装句： 谓语的一部分或者全部放在主语之前的句子称为倒装句。

1、THERE BE句型以及以here、there开头的句子。如： There are a lot of children in the showroom. (在展览室里有许多的小孩。)/ Here comes the bus. (公交车来了。) / There goes the bell. (铃响了。) / The door opened and in came Mr Lee. (门开了,李先生走了进来。)

2、用“So / Nor / Neither + 助动词 + 主语”倒装结构表示第二个人物的情况与上文的人物情况相同。如：Tom went to the beach last week, and, so did I. (Tom上个星期去了海滩,我也是。) / Li Mei’s bought nothing from the shop. Neither has Jim. (李梅没有在店里买什么,Jim也没有买。)

3、在疑问句中,通常使用在主语之前安放助动词的倒装方法,对主语提问除外。如：How did he find the lost book? (他是怎么样找到丢失的书的？) / Where are they going to spend the summer vacation? (他们打算到哪儿过暑假？)

4、感叹句中通常将被感叹的部分前移,而将句子的主谓语整体后置。 如：What a beautiful flower (it is)! (那是多漂亮的花！)

5、有引号引用某人的原话时,引号外面的主谓一般采用倒装形式放在句尾,但是,若主语是代词则不倒装。如：“What on earth are you doing up there?” said the father. (父

亲说：“你在上边到底干什么？”) / “What on earth are you doing up there?”he said. (他说：“你在上边到底干什么？”)
