小学英语四大时态及句式变化

小学英语四大时态

各时态句式

1、含有be动词的句子：

否定句：在be动词后加not

He is not a teacher. (is not=isn’t)

You were not at home yesterday. (were not=weren’t)

I am not doing my homework.

She is not going to swim tomorrow.

一般疑问句：把be动词提到主语前面，句号变问号

Is he a teacher?

Were you at home yesterday?

Are you doing your homework?

Is she going to swim tomorrow?

(含有情态动词的句子，将情态动词看成be动词，一样方式进行变换)

2、含有实义动词的句子

否定句：请助动词do, 在do后加not，句中实义动词用原形注意：do—does, did, don’t- doesn’t, didn’t

I do not like him. (do not = don’t)

He doesn’t like apples.

You didn’t like him.

一般疑问句：在请助动词do, 将do提到主语前面，句中实义动词用原形

Do you like me?

Does he like apples?

Did you go to school yesterday?

3、特殊疑问句，助动词和be动词都要放在特殊疑问词后、主语之前
