一般来说,把英语句子改为否定句,只要加上否定词not 就行了。当然也有特殊情况,下面是小编收集整理的一些英语变否定句的方法,大家一起来看看吧!

1、句中有be动词的,在be动词后加not;

2,句中有情态动词的(can ,should,must ,would),在情态动词后面加not;

3.句中没有be动词和情态动词的,在动词前加don’t或doesn’t ;

① 句中动词为原形的,加don’t .如: I like apples. I don’t like apples.

②句中动词为三单式的,加doesn’t,并将三单式的动词还原成原形。

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

4、肯定句中的some在否定句中应改为any

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

特殊形式的否定句

(1)肯定句含有every-的合成词时,变否定句时改为no-。
