My mother is a teacher. 复数名词 are My parents are busy. The cats are cute. 三、be动词的句式 句式 结构 例句 肯定句 主语 + be + ... I am a student. She is tall. 否定句 主语 + be + not + ... I am not a student. She is not tall. （缩写：isn't / aren't） 一般疑问句 Be + 主语 + ...？ Are you a student? Is she tall? 注意：am not 没有缩写形式；is not = isn't；are not = aren't。 Part 2 典型例题 1. 用 am / is / are 填空。 （1）I ______ a student. （2）She ______ my friend. （3）We ______ in the classroom. （4）______ you a teacher? （5）They ______ from China. 【解析】（1）I用am。（2）She是第三人称单数用is。（3）We是复数用are。（4）You用are，句首大写。（5）They是复数用are。 2. 改写成否定句。 （1）I am a teacher. → I ______ a teacher. （2）She is tall. → She ______ tall. （3）They are happy. → They ______ happy. 【解析】（1）am not（am没有缩写）。（2）is not / isn't。（3）are not / aren't。否定句在be动词后加not。 3. 将下列句子改为一般疑问句，并作肯定回答。 （1）You are a student. → ______ a student?
