作者:小兔兔发布时间:2023-02-23浏览:455


英语改否定句如下:

1、句中有be动词(am/is/are/was/were)的,在be动词后加not。

如:I can swim.——I can't swim.

He is a math teacher. → He is not a math teacher.

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

如:There will be a new building next year. → There will not be a new building next year. (will not可以缩写为won’t)

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.
