人教版七年级英语上册期末语法基础知识点复习（全册）（一）be动词。

1、be动词概说。(包括am, are, is)

①连系动词，本身有词义“是”，在句子中和其后的表语一起构成谓语。

e.g. I am tall.(表语)

②助动词，无词义。

e.g. He is playing football.

2、be动词的用法。

①am →主语是单数第一人称（即I）。

e.g. I am…

②be →are 单数第二人称及所有复数。

e.g. You are…The coats are…

○3is →单数第三人称及不可数名词。

e.g. Your father is…The money is…

3、否定句式（即改否定句）：在be动词之后+not, 句子其它部位不变。

e.g. He is not a teacher.

4、缩写形式。

①主语+be，缩写be第一个字母为’，再与主语合并。

e.g. you are →you’re Jack is →Jack’s

②be+not否定形式的缩写，缩写not中“o”为’, 再与be合并。

e.g. is not→isn’t are not→aren’t

③不能缩写的情况：this is, these are, those are, am not及缩略的肯定回答。

e.g. Yes, I am. (I’m 误)

5、含be动词句子的疑问句型转换。

①一般疑问句：将be动词提前，其它照抄不变，最后+？，读升调。（一般第一人称改为第二人称）

e.g. The man in the car is her father.

→Is the man in the car her father?

I’m a middle school student.

→Are you a middle school student?

②一般疑问句的肯否定回答。

肯定回答：Yes, 主语+be. 否定回答：No, 主语+ be+ not.

e.g. Is he old? ——Yes, he is. /No, he is not.

Are you a new student? ——Yes, I am./ No, I’m not.

Is your father at home? ——Yes, he is.

/No, he is not.(isn’t)

注意：①主语必须用代词回答；②肯定回答不能缩写；③回答第二人称，用第一人称回答。

③特殊疑问句（就划线部分提问）。

1) 方法：将句子被提问(即被划线)的部分改为相对应的疑问词，然后置于句首，接着再将be动词或情态动词提前

(置于疑问词之后)，其它部分照抄不变，最后+？(即疑问词+一般疑问句？)

e.g. The man in a red cap is her brother.

→Who is the man in a red cap?

I can sing English songs. →What can you do?

2) 注意：①被提问部分不能再写。

②提问动词(即提问做某事)，在改句子时注意还“do”，表示做什么？

3) 相应的疑问词。

1. 事物→what e.g. That is a cat. →What is that?

2. 地点→where He is at home? →Where is he?

3. 人→who

4)谁的→whose The coat is his. →Whose is the coat?

（提问名词性物主代词whose后不用带物）

（提问形容词性物主代词whose后要带物或人）
