专题: 把肯定句改成否定句

把肯定句改成否定句分以下情况：

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. ③时态为过去时的,要加didn’t 而且动词过去式要改为原形,

例:I went to school yesterday .→I didn’t go to school yesterday .

4.肯定句中的some在否定句中应改为any
