it用作形式宾语的四个特殊句式

it用作形式宾语的四个特殊句式

当不定式、动名词、从句等复杂成分用作宾语且其后跟有宾语补足语时，通常会在宾语补足语前使用形式宾语it，而将真正的宾语移至句末，此时it仍只起先行引导作用，本身无词义。其基本结构为“动词+it+宾语补足语+不定式(动名词或从句)”。如：Ifinditdifficulttodothejobwell.我发现做好这件事不容易。Ithinkitbestthatyoushouldstayhere.我认为你最好住这儿。Wethinkitnousecomplaining.我们认为抱怨是没有用的。Idon’tfeelitdifficulttounderstandtheSpecialEnglish.（我觉得理解英语特别节目并不难。）

Hemakesitarulenevertoborrowmoney.（他立志决不向别人借钱。）

Ithinkitnoneedtalkingaboutitwiththem.（我认为没必要跟他们谈。）

Wethinkitourdutytocleanourclassroomeveryday.

能这样用的动词有：think,make,find,consider,feel,suppose等。为了记忆方便我们可称该句型为"6123结构"。

6指主句中常用的动词：think,believe,make,find,consider,feel；

1指的是形式宾语it；

2指的是宾补的两种形式：形容词或名词；

3指的是真正宾语的三种形式：不定式短语，动名词短语或that引导的宾语从句。但是，以下几种用it作形式宾语的句型比较特殊，同学们需引起注意（同时它们也是高考的常考考点）：1.动词+it+that-从句。如：Itakeit(that)hewillcomeontime.我认为他会准时来的。Youcanputitthatitwasarrangedbefore.你可以说这是以前安排的。Rumorhasitthatthedefenceministerwillsoonresign.据传闻，国防部长不久就要辞职。说明：能用于此结构的动词不多，常见的有have,take,put等。2.动词+it+when(if)-从句。某些表示“喜、怒、哀、乐”的动词，如like,enjoy,love,hate，dislike,appreciate,prefer等，往往不能直接接宾语从句，如：Ilikeitthatyoucame.你来了，我很高兴。Idislikeitwhenyouwhistle.我不爱听你吹口哨。Wereallyappreciateitwhensheofferedtohelp.她来帮忙了，我们十分感激。I’dpreferitifIdidn’thavetodosomuchwork.要是我不必做那么多工作，好就太好了。3.动词+prep+it+that-从句。that引导的宾语从句不能直接作介词的宾语。如：Seetoitthatyou’renotlateagain.注意千万不要再迟到。Looktoitthatthisdoesn’thappenagain.注意不要再发生这种事。Ican’tanswerforitthathewillcome.我不能保证他会来。Youmayrelyonitthathe’llcometomeetyou.你放心，他会来接你的。Youmaydependonitthatweshallalwayshelpyou.（尽管放心，我们会随时帮你的。）

Wouldyouseetoitthatshegetshomeearly?（你负责保证她早到家，好吗？）

Heinsistedonitthathewasinnocent.（他坚持说自己是无辜的。）

说明：能用于此结构的动词不多，常见的有seeto,lookto,insiston,stickto,dependon,answerfor等。4.动词+it+介词短语+that-从句。由及物动词与介词组成的固定搭配中，宾语从句若作该动词的宾语时，须借用it。如：IoweittoyouthatIamstillalive.多亏有你我才仍然活着。Itookitforgrantedthathewouldhelpus.我认为他会帮助我们的。Ileaveittoyourownjudgementwhetheryoushoulddoit.（我让你自己判断这事是否该做。）

Weoweittoyouthattherewasn’taseriousaccident.（多亏了你才没有发生严重事故。）

说明：能用于此结构的动词不多，常见的有takeitforgranted,bringittosb’sattention,oweittosb,keepitinmindthat…等。5.动词+it+as+名词、形容词、从句Thelecturetakesitasencouragingwhensomanystudentsattendhislecture.能用于此句型中的动词有：accept,regard,take,see,view等试比较下列高考题，选出最佳答案：
