高二英语选修七第三单元知识点2

一、不定式做主语：

1、不定式做主语一般表示具体的某次动作。===动名词doing表示习惯的，经常的动作。

e.g:Tofinishthebuildinginamonthisdifficult.

Todosuchthingsisfoolish.

Toseeistobelieve.(对等)

注:1).不定式作主语时,谓语用单数

2).当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。

it做形式主语，不定式放在谓语动词之后常用于下列结构中：

(1)Itis/was+adj.+ofsb.todo…

(2)Itis+adj.+forsb.+todo…

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

(3)itis+a+名词+todo...

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

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

Itrequirescourage/patience/hardwork…todo…

_注意:probable和possible均可作表语，但possible可以用不定式作真实主语，而probable不能用不定式作真实主语。

Itisprobableforhimtocometothemeeting.(错)

Itispossibleforhimtocometothemeeting.

Itispossible/probablethathewillcometothemeeting.

二、不定式做表语

主语是以aimdutyhopeideaintentionplanjobsuggestionwishpurposetask等为中心词的名词词组或以what引导的名词性从句表示，后面的不定式说明其内容,不定式作表语常表示将来或现在的动作或状态。

eg:Myideaistoclimbthemountainfromthenorth.

Yourmistakewasnottowritethatletter.

WhatIwouldsuggestistostartworkatonce.

三、动词不定式作宾语

以不定式结构为宾语的动词有：

ask,agree,care,choose,demand,decide,expect,fail,help,hope,learn,manage,offer,plan,prepare,pretend,promise,refuse,want,wish等只能用动词不定式作宾语

口诀(接不定式作宾语的动词)

想要学习早打算(wantlearnplan)

快准备有希望(preparehopewishexpect)

同意否供选择(agreeofferchoose)

决定了已答应(decidebedeterminedpromise)

尽力去着手做(manageundertake)

别拒绝别假装(refusepretend)

失败不是属于你(fail)

e.g.Tomrefusedtolendmehispen.

Wehopetogettherebeforedark.

Thegirldecidedtodoitherself.
