高三英語(yǔ)知識(shí)點(diǎn)總結(jié)

一、不定式做主語(yǔ)：

1、不定式做主語(yǔ)一般表示具體的某次動(dòng)作。===動(dòng)名詞doing 表示習(xí)慣的，經(jīng)常的動(dòng)作。

e.g: To finish the building in a month is difficult.

To do such things is foolish.

To see is to believe. (對(duì)等)

注: 1). 不定式作主語(yǔ)時(shí),謂語(yǔ)用單數(shù)

2). 當(dāng)主語(yǔ)較長(zhǎng)，謂語(yǔ)較短時(shí)，常用it做形式主語(yǔ)，而將不定式放到謂語(yǔ)的后面。

it做形式主語(yǔ)，不定式放在謂語(yǔ)動(dòng)詞之后常用于下列結(jié)構(gòu)中：

(1)It is/was +adj.+of sb. to do…

(2) It is +adj.+for sb.+to do…

It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary

(3) it is +a +名詞+ to do...

It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do

It takes (sb.) some time / courage / patience …to do…

It requires courage / patience / hard work… to do…

_注意: probable 和 possible 均可作表語(yǔ)，但possible可以用不定式作真實(shí)主語(yǔ)，而probable不能用不定式作真實(shí)主語(yǔ)。

It is probable for him to come to the meeting.(錯(cuò))

It is possible for him to come to the meeting.

It is possible / probable that he will come to the meeting.

二、不定式做表語(yǔ)

主語(yǔ)是以aim duty hope idea intention plan job suggestion wish purpose task 等為中心詞的名詞詞組或以 what 引導(dǎo)的名詞性從句表示，后面的不定式說(shuō)明其內(nèi)容, 不定式作表語(yǔ)常表示將來(lái)或現(xiàn)在的動(dòng)作或狀態(tài)。

eg :My idea is to climb the mountain from the north.

Your mistake was not to write that letter.

What I would suggest is to start work at once.

三、動(dòng)詞不定式作賓語(yǔ)

以不定式結(jié)構(gòu)為賓語(yǔ)的動(dòng)詞有：

ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn, manage, offer, plan, prepare, pretend, promise, refuse, want, wish等只能用動(dòng)詞不定式作賓語(yǔ)

口訣(接不定式作賓語(yǔ)的動(dòng)詞)

想要學(xué)習(xí) 早打算( want learn plan)

快準(zhǔn)備有希望( prepare hope wish expect)

同意否供選擇(agree offer choose)

決定了已答應(yīng)(decide be determined promise)

盡力去著手做(manage undertake)

別拒絕別假裝(refuse pretend)

失敗不是屬于你(fail)

e.g.Tom refused to lend me his pen.

We hope to get there before dark.

The girl decided to do it herself.
