高考英語必背知識點總結(jié)歸納

不定式的構(gòu)成

1、不定式的一般式：不定式的一般式所表示的動作通常與主要謂語的動作同時或幾乎同時發(fā)生，或是在它之后發(fā)生。

如：They invited us to go there this summer.他們邀請我們今年夏天去那兒。He stood aside for me to pass.他站到一邊讓我通過。

2、不定式的完成式：不定式的完成式所表示的動作在謂語所表示的動作之后發(fā)生，它在句中可作表語、狀語、賓語，有時也可作主語、定語等。

如：She seemed to have heard about this matter.她似乎已聽說過這件事。

I am sorry to have kept you waiting so long.我很抱歉讓你等了這么久。

I meant to have told you about it,but I happened to have an important thing to do.我本來想告訴你這件事的，但我碰巧有一件重要的事要做。

It has been an honor for me to have traveled so much in your country.對我來說，在你們國家旅行這么多地方是一件很榮幸的事情。

3、不定式的進行式：不定式的進行式表示正在進行的與謂語動詞同時發(fā)生的動作。它在句中可以用作除謂語以外的所有成分。

如：It’s nice of you to be helping us these days.你真好，這些天一直幫我們。

He pretended to be listening to the teacher carefully.他假裝在認(rèn)真地聽老師講課。We didn’t expect you to be waiting for us here.我們沒料到你一直在這兒等我們。

4、不定式的完成進行式：如果不定式表示的動作是謂語所表示

5、動詞不定式的否定形式是由not或never加不定式構(gòu)成。如：Try not to be late again next time.盡量下次不要再遲到。He wished us never to meet her again.他希望我們永遠(yuǎn)不要再見到她。

6、疑問詞+動詞不定式：不定式和疑問詞whether,what,which,whom,where,when,how,why等連用可以在句中起名詞的作用，通常跟在tell,know,show,decide,learn,wonder,explain,advise,teach,discuss,find out等動詞后面作賓語，有時也可以充當(dāng)主語、表語等。

如：On hearing the news,he didn't know whether to laugh or to cry.聽到這個消息，他不知道該哭還是該笑。

When to hold the meeting has not decided.什么時候開會還沒有決定。

The most important problem is how to get so much money.最重要的事情是如何搞到這么多錢。

介詞后一般不直接接不定式，但可以接疑問詞+不定式短語作賓語。

如：Mary gave some advice on how to learn English.瑪麗提了一些如何學(xué)習(xí)英語的建議。

I have no idea of how to do it.我不知道該怎么做。

(doesn′t是助動詞，無詞義;like是主要動詞，有詞義)

2) 助動詞協(xié)助主要動詞完成以下功用，可以用來：
