目前大家應(yīng)該是對(duì)什么時(shí)候用does比較感興趣的，所以今天好房網(wǎng)小編CC就來(lái)為大家整理了一些關(guān)于什么時(shí)候用does方面的相關(guān)知識(shí)來(lái)分享給大家，希望大家會(huì)喜歡哦。

歸納起來(lái), do ,does 的用法有四方面：

一、用作一般的動(dòng)詞，均可。do是一不規(guī)則變化的動(dòng)詞(do ,did,done)。

do，據(jù)人稱和單復(fù)數(shù)的不同而有字形的變化。第一第二人稱，以及第一、二、三人稱的復(fù)數(shù)時(shí)，都用 do。

第三人稱單數(shù)時(shí)，用 does( he does she does it does )

例如: I do my homework on Sunday.

You do your homework on Sunday.

We do our homework on Sunday.

You do your homework on Sunday.

They do their homeworkon Sunday.

He does his homework on Sunday.

She does her homework on Sunday.

二.當(dāng)助動(dòng)詞用，用它來(lái)構(gòu)成疑問句.這時(shí)它本身沒有實(shí)義，只是一個(gè)構(gòu)成疑問句的符號(hào)而已.這種用法時(shí)，它隨人稱和數(shù)的變化規(guī)則與上述相同，只是把它放到句子的最前面(句首)。例如：

Do I ...............?

Do you .............?

Do we ..............?

Do you .............?

Do they ............?

Does he ............?

Does she ...........?

Does it ............?

三.當(dāng)助動(dòng)詞用，與 not 連用使句子構(gòu)成否定句。其隨人稱和數(shù)的變化規(guī)則與上述相同。例如：

I do not ..................? (do not 可簡(jiǎn)化為 don't ,下同)

You do not ................?

We do not..................?

You do not.................?

They do not................?

He does not................? (does 可簡(jiǎn)化為 doesn't,下同)

She does not...............?

四.當(dāng)作助動(dòng)詞,本身在句子中無(wú)實(shí)義，只是加強(qiáng)句子中動(dòng)詞的語(yǔ)氣，其隨人稱和數(shù)的變化同上。例如：

Do write to me.(一定寫信給我!)

Never do I see such a fool.(我從來(lái)沒見過這樣的蠢才.)

She does come.(她的確來(lái)了.)

按詞性，do 還可以用作名詞。其意是"欺騙";"宴會(huì),宴請(qǐng)"。例如：

It's all a do.(完全是欺騙.)

We have got a do on to-night.(家里今晚請(qǐng)客.)
