Unit 1 Grammar -2021-2022学年七年级英语上册同步课时精讲精练（牛津译林版）

Unit 1 This is me! Grammar 知识点梳理及练习： be动词用法 ①be+地点副词/地点短语 We are at school. He is in the hospital. The boy is here. ②系动词+形容词 We are fat and tall. She is happy. ③be+名词 She is a nurse. We are students. be动词否定形式：isn’t, am not, aren’t 变疑问句时，把be动词移到句首，变否定句时，not放在be动词后面 如：Is the school very big? The school is not/isn’t very big. 注意：be动词的祈使句是动词原形开头。 如：Be careful! be动词的祈使句的否定句必须在句首加Don’t或Never。 如：Don’t/Never be late! ④people, the police或类似the Greens词做主语时是复数。 class/family应该根据句中的意思来判断其单复数；表示其成员时用复数，表示一个单位时是单数。 如：The family now live in Wuxi. The large family has seven children. ⑤there be句型中be动词和其后的主语保持一致（即就近原则）。 如：There is a TV set and six lights in our classroom. 练习：1. -Is his name Jim? -________. A. Yes, it’s B. Yes, he’s C.
