初中英语七年级必备_整理版_句型转换(陈述句变一般疑问句特殊疑问句及练习)

初中英语句型转换

基本助动词只有三个：be, do, have, 他们没有词汇意义，只有语法作用，如协助构成进行体，完成体，被动态，否定句，疑问句等。

一、肯定句改否定句的方法——一步法

1. 有be动词/情态动词：在be动词/情态动词后后加not。

2. 无be动词/情态动词，在动词前加don’t/doesn’t/didn’t。

3. some 改成any。

4. 情态动词：can，will，should，must，may。

把下列句子变成否定句：

1. I am listening to music. _______________________________________

2. Mike is a student. _______________________________________

3. Sarah can clean the classroom. _______________________________________

4. They are in the zoo. _______________________________________

5. There are some flowers in the vase. _______________________________________

6. This is my sister. _______________________________________

7. We are sweeping the floor. _______________________________________

8. We need some masks. _________________________________

9. They like making the puppet. _________________________________

10. Su Hai and Su Yang live in a new house._______________________________________________

11. I put a book on my head. _________________________________________________

12. They sing “In the classroom” together. _______________________________________________

13. We play basketball on Sundays. _________________________________________________

14. Tom likes listening to music ____________________________________________

二、肯定句改一般疑问句的方法——三步法

1. 有be动词/情态动词：be动词/情态动词提到句首，其余照抄，(some改any，my改your）句末用问号。

2. 无be动词/情态动词，在句首加Do/Does/Did，其余照抄，(some改any，my改your）句末用问号。

3. 加Does、did 的句子注意，句子动词要变成原型。

例如：陈述句: They are in the park. He can play the guitar..

一般疑问句: Are they in the park? Can he play the guitar?

陈述句: I like the ducks. He likes the dogs.

一般疑问句：Do you like the ducks? Does he like the dogs?
