一般來說,把英語句子改為否定句,只要加上否定詞not 就行了。當(dāng)然也有特殊情況,下面是小編收集整理的一些英語變否定句的方法,大家一起來看看吧!

1、句中有be動詞的,在be動詞后加not;

2,句中有情態(tài)動詞的(can ,should,must ,would),在情態(tài)動詞后面加not;

3.句中沒有be動詞和情態(tài)動詞的,在動詞前加don’t或doesn’t ;

① 句中動詞為原形的,加don’t .如: I like apples. I don’t like apples.

②句中動詞為三單式的,加doesn’t,并將三單式的動詞還原成原形。

如:He likes apples. He doesn’t like apples.

4、肯定句中的some在否定句中應(yīng)改為any

如:There are some students in the classroom. There are not any students in the classroom.
