  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 konw 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。

  4、代替前文出现的“谓语+宾语”,使句子结构更简洁。

  Lily likes swimming,so do I.

  Lily喜欢游泳,我也喜欢。

  I can dance as well as you do.

  我能跳舞跳得跟你一样好。

  常用短语

  1、do me a favor.

  帮我一个忙

  Can you do me a favor?

  你能帮我一个忙吗?

  2、be/have nothing to do with sb.

  与某人无关

  What are you doing?

  你在做什么?

  ——There is nothing to do with you.

  与你无关。

  3、that's done it

  这下完了。

  That's done it.You've completely broken it this time.

  这下完了,你这下可把它全弄坏了。

  4、do right、do well

  做得对、做得好

  You do right to quit smoking.

  你做得对,把烟戒了。

  5、nothing doing!

  语气不叫强硬的“不行!”

  Can you pick me up at the railway station tomorrow?

  ——Nothing doing!

  你明天能到火车站接我吗?

  ——不行!

  6、do out of

  (以不当手段)剥夺 使丧失

  She was done out of her promotion.

  她升职失败了。

  7、do away with

  终止、废除、干掉

  She tried to do away with me.

  她想要干掉我。

  They thinked it was time to do away with monarchy.

  他们认为是时候该废除君主制了。

  do的用法不止以上归纳的那些,特别是做实义动词的部分。do做实义动词时的用法很繁琐、很细碎,需要大家平时学习生活中多积累。但是do做助动词时,基本就是以上四种用法。

Do与Does的基本用法

  do与does的基本用法

  基本用法:does 是 do 的三人称单数形式1.作实义动词,也叫形为动词。和普通的动词一样,有自己的实际意思,表示“做”例如:do homework, do exercises等.主语是I/We/You/They或者复数名词时,动词用do例如:I often do my homework in the evening ..主语是He/She/It或者其他单数名词时,动词用does例如:She often does homework in the evening .2.作助动词,无实际意思。通常用于疑问句和否定句。(1)用于一般疑问句。直接在句首加上do/does,注意大小写和部分人称及动词的变化。例如:I like apples.-------Do you like apples?Yes, I do. /No, I don/////'t..主语是三人称单数时,记得用does.例如:She likes apples.-------Does she like apples?Yes, she does. /No, she doesn/////'t.(2)用于否定句时,在句子中加上don/////'t或者doesn/////'t.例如:I don/////'t like apples. She doesn/////'t like apples.练习:填空。

  ___ they like ping--pong?
