句 型 转 换

一、 肯定句改否定句的方法 — 一步法

1、 在be动词（am ,is, are ，was, were）后加否定词not。如：is not ， are not ， am not， was not， were not；其中is not=isn’t, are not= aren’t, 前者为“完全形式”，后者为“缩略形式”。

2、 在can，should，will等后加not。如：cannot， should

not， will not；

3、上述都没有的，在动词前加助动词do, does, did的否定形式don’t/doesn’t/didn’t。

4、 some 改成any。

如： I am a girl. → I am not a girl.

You are a student. →You are not a student.

→You aren’t

a student.

This is Tom’s bag, → This is not Tom’s bag.

→ This

isn’t Tom’s bag.

答题方法是；否定词not在be后边。

二、 肯定句改一般疑问句的方法 —

三步法

1、 把be动词放在句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。

2、 把can，shall， will等放到句首，剩下的照抄，（some

改成any，I改成you，my改成your，）句点改成问号。

3、 上述都没有的，在句首请助动词Do/Does/Did帮忙，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。

注意：句首的第一个字母要大写，句尾标点应为“？”。如：

I am in Class 6. →Are you in Class 6?

You are from America. →Are you from America?
