高二英語選修七第三單元學(xué)問點2

一、不定式做主語：

1、不定式做主語一般表示詳細(xì)的某次動作。===動名詞doing表示習(xí)慣的，常常的動作。

e.g:Tofinishthebuildinginamonthisdifficult.

Todosuchthingsisfoolish.

Toseeistobelieve.(對等)

注:1).不定式作主語時,謂語用單數(shù)

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

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

(1)Itis/was+adj.+ofsb.todo…

(2)Itis+adj.+forsb.+todo…

Itiseasy/difficult/hard/foolish/unwise/right/wrong/unnecessary

(3)itis+a+名詞+todo...

Itisapity/apleasure/apleasantthing/one’sduty/anhonor/ashame/acrime/noeasyjob…todo

Ittakes(sb.)sometime/courage/patience…todo…

Itrequirescourage/patience/hardwork…todo…

_留意:probable和possible均可作表語，但possible可以用不定式作真實主語，而probable不能用不定式作真實主語。

Itisprobableforhimtocometothemeeting.(錯)

Itispossibleforhimtocometothemeeting.

Itispossible/probablethathewillcometothemeeting.

二、不定式做表語

主語是以aimdutyhopeideaintentionplanjobsuggestionwishpurposetask等為中心詞的名詞詞組或以what引導(dǎo)的名詞性從句表示，后面的不定式說明其內(nèi)容,不定式作表語常表示將來或現(xiàn)在的動作或狀態(tài)。

eg:Myideaistoclimbthemountainfromthenorth.

Yourmistakewasnottowritethatletter.

WhatIwouldsuggestistostartworkatonce.

三、動詞不定式作賓語

以不定式結(jié)構(gòu)為賓語的動詞有：

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

口訣(接不定式作賓語的動詞)

想要學(xué)習(xí)早準(zhǔn)備(wantlearnplan)

快預(yù)備有盼望(preparehopewishexpect)

同意否供選擇(agreeofferchoose)

打算了已答應(yīng)(decidebedeterminedpromise)

盡力去著手做(manageundertake)

別拒絕別假裝(refusepretend)

失敗不是屬于你(fail)

e.g.Tomrefusedtolendmehispen.

Wehopetogettherebeforedark.

Thegirldecidedtodoitherself.

_留意:某些及物動詞可用-ing也可用動詞不定式作賓語但意義不同的有

stopgoonrememberforget
