在一般现在时中be 动词有三种形式：am , is , are。常译作“是”, 它后面常跟名

词，形容词或介词短语，说明主语的身份，特征或所处位置。例如： I am a student. She is tall. They are in the classroom. 名词 形容词 介词短语

含有be 动词的一般现在时否定句是be 动词后加“not ”， 一般疑问句是将be 动词提到句首。见下表： 肯定句式 否定句式 一般疑问句式 及简略答语 I am… I am not…. Are you …? Yes, I am. No, I am not. You are… You are not …. Are you…? Yes, I am. No, I’m not. He/ She/It is … He/ She/ It is not Is he/she/it ….? Yes, he/she/it is. No, he/she/it isn’t. We are… We are not… Are you…? Yes, we are. You are… You are not… Are you…? No, we are They are… They are not… Are they…? Yes, we are. No, we aren’t. Yes, they are. No, they aren’t. 1

be动词用法歌 我用am,你用are，is跟着他，她，它。单数名词用is，复数名词全用are。 变疑问，往前提，句末问号莫丢弃。变否定，更容易，be后not莫忘记。 疑问否定任你变，句首大写要注意。 ◎基础练习
