由于用了很长时间,这本书看上去很旧。
Usingthebook,Ifindituseful.
在使用的过程中,我发现这本书很有用

【二】
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.

Thegirldecidedtodoitherself.
