does后面的动词用什么形式

如题所述

第1个回答  2022-05-28

动词原型。英语中do和does的用法:构成一般疑问句,例如,Do you want to pass the cet?你想通过大学英语测试吗?Did you study German?你们学过德语吗?do+not构成否定句,例如,I do not want to be criticized.我不想挨批评。He doesn't like to study.他不想学习。

Do做助动词时

助动词就是没有实际意义的动词,主要作用是帮助谓语构成一定的语法作用。

1、放在谓语动词前,起强调作用。

She likes you.

她喜欢你。

She does like you.

她确实喜欢你。

I do know you, but I don't quite familiar with you.

我确实认识你,但对你并不是很熟。

2、放在句首,构成疑问句。

构成一般疑问句:

I know what happened.

我知道发生了什么。

Do you know what happened?

你知道发生了什么吗?

Does Lily want to go home now?

Lily现在想回家了吗?

do放在句首做疑问词,回答用:

Yes,I do.

No,I don't.

构成反义疑问句:

Rachel did say she would be here at 8:00,didn't she?

瑞秋确实说过她会8点到这里,不是吗?

Yes,she did.是的,她说过。

No,she didn't.不,她没说过。

3、与not连用,放在谓语动词前,构成否定句。

I know what happened.

我知道发生了什么。

I don't know what happened.

我不知道发生了什么。

I like swimming.

我喜欢游泳。

I don't like swimming.

我不喜欢游泳。
