替代作主語的從句、動(dòng)詞不定式、動(dòng)名詞,而把真正作主語的從句、動(dòng)詞不定式、動(dòng)名詞置于句尾。四、it

用作形式主語1.代替動(dòng)詞不定式做主語1)Itbeadj.(forsb.)todosth.此處adj.

通常為描述事件的形容詞:easy,difficult,necessary,important,possible,dangerous,right,wrong,legal,useful,useless,Itisillegal

todriveacarwithoutalicense.2)Itbeadj.ofsb.todosth.此處adj.

通常為描述人的形容詞:kind,,nice,rude,polite,

cruel,considerate,thoughtful,careful,careless,foolish,stupid,clever,wise,crazy.It'skindofyoutohelpmewiththeproblem.It’s(well)worthone’swhiledoing/todo…Itisworthmywhiletoexplorethecity.這值得我花時(shí)間/精力勘察這個(gè)城市It’s(well)worthwhiledoing/todo…Itisworthwhiletoexplorethecity.It‘snogood/use/pleasuredoing…Itisnousestudyingonlyatschool.2.代替動(dòng)名詞做主語3.代替主語從句作形式主語Itisclear(obvious,true,possible,certain…)that...（注意沒有itissurethat）該句型中it是形式主語,真正的主語是that引導(dǎo)的主語從句,常譯為“清楚(顯然,真的……)”,是主語從句最常見的一種結(jié)構(gòu)。e.g.Itisveryclearthathe’stall.①Itisadj.+

從句Itissaid(reported/believed.....)that...該句型中的it仍是形式主語,真正主語是that引導(dǎo)的主語從句;該結(jié)構(gòu)常譯為“據(jù)說(據(jù)報(bào)道,據(jù)悉…)”。ItissaidthathehascometoBeijing.HeissaidtohavecometoBeijing.②Itisv-edthat…

③Itis+noun+

從句

Itisapity(ashame/anhonor/agoodthing/afact/asurprise/...)that...該句型中,that后的從句一般用虛擬語氣(should+動(dòng)詞原形),should可省去。表示出乎意料,常譯為“竟然”。沒有這種意義時(shí),則不用虛擬語氣。如：Itisapitythatsuchathing(should)happeninyour

class.這種事竟然發(fā)生在你們班上,真是遺憾！Itisapitythatyoucan’tcome.

你不能來，真是遺憾！五、it作形式賓語

當(dāng)復(fù)合賓語中的賓語是不定式、動(dòng)名詞，賓語從句時(shí),往往把賓語放在它的補(bǔ)足語后面，而用it作形式賓語,放在賓語補(bǔ)足語之前。

該句型中的it作形式賓語,常用的動(dòng)詞有think,believe,make,find,consider,feel等。Ithinkitnousearguingwithhim.參考：

Itisnousearguingwithhim.Ifounditveryinterestingtostudy

English.參考：ItwasveryinterestingtostudyEnglishHemadeitclearthathewasnotintothecar.參考：

Itwasclearthathewasnotintothecar.

討厭類：hate,dislikeIwouldappreciateitifyoupaidincash.Ilikeitwhenmymotherishappy.Ihateitwhenpeopletalkwiththeirmouthsfull.其他類：seetoitthat,oweittosbthat.rely/dependonitthat,takeitforgrantedthat,leaveittosbthat,makeitarulethat…注意：keep/bearinmindthat

中間沒有itSeetoitthatthebabymustbefedwhenhungrybutnottoomuch.留意，務(wù)必Hetookitforgrantedthathewouldpasstheexam.想當(dāng)然地認(rèn)為Don’tdepend/relyonitthathewillarriveontime.(指望)IowedittoTomthatIfoundthejobIwanted.把…歸功于某人Iwillleaveittoyouwhetheryougoabroadornot.IhavemadeitarulethatIwilldosomeEnglishreadingeveryday.習(xí)慣做，規(guī)定必須做，經(jīng)常做六、用于強(qiáng)調(diào)句型中It+be+被強(qiáng)調(diào)部分+that/who(aperson)從句I

whenthatItisnotuntil+被強(qiáng)調(diào)部分+that...該句型也是強(qiáng)調(diào)句型。主要用于強(qiáng)凋時(shí)間狀語,譯成漢語“直到……才……”,可以說是not...until...的強(qiáng)調(diào)形式。如:

ItwasnotuntilshetookoffherdarkglassesthatIrealizedshewasafamousfilmstar.=NotuntilshetookoffherdarkglassesdidI

realizeshewasafamousfilmstar.=Ididn’trealizeshewasafamousfilmstar

untilshetookoffherdarkglasses.七、it常用的固定搭配
