一．定义：表示经常或习惯性发生的动作，事情或存在的状态。
二．构成形式：主语+动词原形+其他…（当主语为第三人称单数时，动词要发生
改变）
1. be动词的变化
肯定句：主语+be (am, is, are)+其他。如：I am a boy. 我是一个男孩。 否定句：主语+be+not+其他。如：He is not a worker. 他不是工人。 一般疑问句：Be+主语+其他？如：--Are you a student?
--Yes, I am. / No, I’m not. 2.行为动词的变化
当主语为第一，第二人称及复数时，助动词为do
肯定句：主语+动词原形+其他。如：We often play basketball after school. 否定句：主语+don’t+动词原形+其他。如：We don’t play basketball after school. 一般疑问句：Do+主语+动词原形+其他？ 如：Do you often play basketball after school?
Yes, we do. / No, we don’t.
当主语为第三人称单数（简称“三单”）时，助动词为does. 肯定句：主语+动词三单形式+其他。如：He swims well.
否定句：主语+doesn’t+动词原形+其他。如：He doesn’t swim well. 一般疑问句：Does+主语+动词原形+其他。
如：Does he swim well? Yes, he does. / No, he doesn’t. 特殊疑问句：疑问词+以does开头的一般疑问句？ 如：How does your father go to work?
三．用法：
①现阶段经常性、习惯性动作,常与表示频度的时间状语连用。
时间状语：often, always, sometimes, usually, never, every day, every year,
on Sundays, twice a year
如：I leave home for school at 7 every morning.
②目前的状态；
如：Guangzhou is 2313 kilometres away from Beijing. ③客观真理；
如：The earth moves around the sun. Shanghai lies in the east of China.
④在时间状语从句或条件状语从句中，一般现在时代替一般将来时。（主将从现）
如：I'll help you as soon as you have problem
构成：主语是第三人称单数时，作谓语的行为动词要加词尾-s(-es)，其他人称和数用动词原形。
四．动词变化规则：
1. 一般情况下，直接加s。如:get---gets
2. 以s、x、sh、ch、o 结尾的动词，加es。如:do---does 3. 辅音字母加y结尾，改y为i，加es。如:study---studies 4. 元音字母加y结尾，直接加s。如:enjoy---enjoys
真题再现
1.This plane f___ to Guangzhou every day. （09年大联盟）
解析：题目中every day，可以看出是每天，要用一般现在时，而一般现在时就要去看主语是不是三单，本题中的主语是This plane，是三单，那么根据题意可以看出要填fly，它的三单形式是flies,所以答案为flies
2.My father ____ a new car. He ___ it very much. （09年大联盟） A.have, like B.has, likes C.has, like D.have, likes
解析：根据题意可以看出是表示一种状态。我爸爸有一辆新车，他很喜欢。从而可以判断出要用一般现在时。然而my father和he都是三单，所以动词都要变形，答案为B
3.Where ____ he ____(live)? -- He _____(live) in Nanjing. （09年大联盟）
解析：根据题目可以看出是住在哪里，一种状态，所以要用一般现在时。然后he是三单，所以答案为does,live,lives
4.My father ____(like) ____(play) basketball.（09年大联盟） 解析：我爸爸喜欢打篮球，是一种习惯，所以用一般现在时，my father是三单，所以like要加s，然而like后的动词要用ing形式，所以答案为likes, playing.
5.Lily likes spring best.（对划线部分提问） （09年大联盟） ____ season ____ lily like best?
解析：根据题目可以看出用的是一般现在时。然后like是实义动词，所以改特殊疑问句，需要用疑问词加一般疑问句，所以答案为Which,does.
6. __________ his father,David _________ playing football .（10年大联盟）
A. Like, like B. Likes, likes
C.Likes, like D. Like, likes
解析：这里考察了like的词性，第一个不是不是动词，所以没有变化，然而后面是表示喜欢，主语为David，是三单，所以like要加s.答案为D
7. My father (like) (play) basketball.（11年大联盟） 解析: 我爸爸喜欢打篮球，是一种习惯，所以用一般现在时，my father是三单，所以like要加s，然而like后的动词要用ing形式，所以答案为likes, playing.
8. (do) Nancy often (visit) her grandparents at the weekends?（11年大联盟）
解析:题目中often是经常的意思,可以看出要用一般现在时,然而Nancy是三单，所以答案为Does,visit.
9. If it _________rain tomorrow ,we'll have a picnic in the park.（11年大联盟）
A. won't B. doesn't C. isn't D. don't 解析：这里考察的是由if引导的主将从现，所以if引导的从句要用一般将来时，rain是实义动词，主语是it,三单，所以要借助助动词doesn’t.
10.________ your dad often _________ (water) the flowers on weekdays.（12年大联盟）
解析：从题目on weekdays可以看出是在平时，所以要用一般现在时，而主语your dad是三单，所以答案为Does, water.
11. My aunt ____________ (have) a farm. There are some____________ (deer)in it.（12年大联盟）
解析：通过题目可以看出，我的阿姨有一个农场，是一种状态，而主语my aunt是三单，所以have要变成has.答案为has,deer.
12.My father usually ________ (cook) at 5 o’clock.（13年大联盟） 解析：通过题目中的usually可以看出要用一般现在时，而主语My father是三单，所以cook要加s,答案为cooks.
13.________ Helen like ________ (swim) every day? （13年大联盟） 解析：通过题目every day可以看出要用一般现在时，而Helen是三单，所以要变化，swim是实义动词，所以要借助助动词does，答案为Does,swim.
14.He does some reading every day. （改否定句） （13年大联盟） He ________ ________ ________ reading every day.
解析：因为does是实义动词，所以改否定句要借助助动词doesn’t，助动词后的动词要用原形。所以答案为doesn’t do any.
15.The teacher always takes good care of my son in the kindergarden.（改成同义句）（13年大联盟）
The teacher always ________ ________ my son well in the kindergarden. 解析：通过题目可以看出takes care of是照顾的意思，主语为the teacher是三单，所以take加了s,而照顾另一个同义词是look after，所以答案为looks after.
