句型转换

句型之间的转换即陈述句,否定句,一般疑问句,肯定回答否定回答,单复数转化,同义句和就划线部分提问之间的问题。我们把它分为三种情况:1,有be动词的句子;2,有情态动词的句子;3,实义动词的句子。

(一) 有be动词的句子:This is a book.

(1) 变否定句只需要在be动词后面加上not:

This is not a book.

(are not=aren’t; is not=isn’t)

(2) 变一般疑问句要做到“一提三改”(be 动词提前,大写

改小写,小写改大写,句点换问号);第一人称换为第二人称.

eg: Is this a book?

(3) 肯,否定回答:怎么问就怎么答。(注意: this,that---it

these,those---they)

eg: 例句: I am a teacher. These are my friends. --- I am not a teacher. --- These aren’t my friends. --- --- Are these your friends? --- Yes, I am. \ No, I am not. --- 练习: That is a red pencil. We are students. They are yoyos.

(二)没有be动词,只有情态动词的句子: I can ride a bike.

(1)变否定句只需要在情态动词后面加上not:

eg : I can’t ride a bike.

(can not=can’t; must not=mustn’t )

(2) 变一般疑问句要做到“一提三改”(情态动词提前,大

写改小写,小写改大写,句点换问号);第一人称换为

第二人称.

eg: Can you ride a bike?

(3) 肯,否定回答:怎么问就怎么答。(注意:must提问的否

定回答有些特殊)。

eg: Yes, I can. \ No, I can’t.

例句:I can speak English. Mary can swim.

--- I can’t speak English. --- Mary can’t swim.

--- Can you speak English? --- Can Mary swim?

--- Yes, I can.\No,I can’t. --- Yes, she can.\No, she can’t. 练习:

The dog can eat bone. They can fly a kite.

(三) 如果句中既没有be动词,也没有情态动词,只有实义动词时.

我们在做句型转换时就要借助助动词(do,does,did).

do—当主语为第一,二人称或第三人称复数时;

does---当主语为第三人称单数时:

did--- 当句子为过去式时。

(1) 变否定句只需要在助动词后面加上not:

eg: I like apples.---I don’t like apples.

(do not=don’t; does not= doesn’t; did not=didn’t)

(2) 变一般疑问句要做到“一提三改”(助动词提前,大写改

小写,小写改大写,句点换问号);第一人称换为第二

人称.

eg: Do you like apples?

(3) 肯,否定回答:怎么问就怎么答。

Yes, I do;\ No, I don’t.

例句:They play soccer. He plays soccer

--- They don’t play soccer. --- He doesn’t play soccer. --- Do they play soccer? --- Doea he play soccer? --- Yes, they do.\ No,they don’t. --- Yes,he does.\ No,he doesn’t. 练习:I eat lunch at 12:00. She goes to bed at 9:00.

(四)就划线部分提问,其实就是把句子变为特殊疑问句。

(1) 先将句子变为一般疑问句。

Is this your bag?

(2) 考虑划线部分问的是什么内容,就运用相应的特殊疑问词,至于句前。(my是我的,及问物品主人,故用Whose。)然后去掉划线内容即可。

Whose is this bag?

例句: My book is on the desk. This is a desk.

--- Is your book on the desk? --- Is this a desk? --- Where is your book? --- What is this? 练习:
