Discovering"It"

1.Itrainsheavily.指天氣

2.Itis20kilometersfromGranddad'shousetoJames5.，指距離

3.ItisNovember11,2005.指日期

4.Itis9o9clockatnight.指時(shí)間

5.Itisbadtosmoke.形式主語(yǔ)

6.Itisnogoodsmoking.形式主語(yǔ)

7.Itislikelythathewillsucceed.形式主語(yǔ)

Step3Theuseof“it"

一、“it”作人稱代詞

Lit的最基本用法是作代詞，主要指剛提到的事物，以避免重復(fù):

Xi'anisabeautifulcity,isn'tit?

Theywatchedthetrainuntilitdisappearedinthedistance.

2.也可以指動(dòng)物或嬰兒（未知性別的嬰兒或孩子）:

Isthisyourdog?No,itisn't.

二、it作非人稱代詞

it有時(shí)并不指具體的東西，而泛指天氣、時(shí)間、日期、距離、價(jià)值、度量、溫度、環(huán)境等,

稱為非人稱的it：

0.指天氣：

Itisalovelyday,isn'tit?

Itisabitwindy.

2.指時(shí)間:

Itwasnearlymidnightwhenshecameback.

3.指環(huán)境:

Itwasveryquietinthecafe.

4.指距離:

Itishalfanhour'swalktothecitycentrefrommyhome.

5.指日期:

Whafsthedatetoday?It'sMay1,2007.

6.指季節(jié):

Itissummernow.

7.指度量：

Itisabout5kilograms.

8.指價(jià)值：

——What'sthecostoftheT-shirt?

——Itis150Yuan.

三、it用作形式主語(yǔ)

替代作主語(yǔ)的從句、動(dòng)詞不定式、動(dòng)名詞，而把真正作主語(yǔ)的從句、動(dòng)詞不定式、動(dòng)名詞置

于句尾。

1.代作主語(yǔ)的動(dòng)詞不定式，其句型為

(1)Itbeadj.(forsb.)todosth.

此處adj.通常為描述事件的形容詞：easy,difficult,hard,necessary,unnecessary,possible,

impossible,likely,unlikely,right,wrong,important,unimportant,legal,illegal,well-mannered,

ill-mannered,polite,impolite,clear,obvious,certain,suitable,proper,fit,useful,useless,

dangerous...

Itisillegal(forateenager)todriveacarwithoutalicense.

(2)Itbeadj.ofsb.todosth.

此處adj.通常為描述人的形容詞:kind,unkind,nice,rude,cruel,considerate,thoughtful,

thoughtless,careful,careless,silly,foolish,stupid,clever,wise,crazy.

It'skindofyoutohelpmewiththeproblem.

(3)It替代作主語(yǔ)的動(dòng)名詞的常見(jiàn)句型

It'snogood/usedoing...

It's(well)worthdoing...

It's(well)worthone'swhiledoi.ng/todo...

It*s(well)worthwhiledoing/todo

It'snousecryingoverspiltmilk.

2.作形式主語(yǔ)替代主語(yǔ)從句

1.Itisclear(obvious,true,possible,certain)that..…

該句型中it是形式主語(yǔ)，真正的主語(yǔ)是that弓|導(dǎo)的主語(yǔ)從句，常譯為“清楚(顯然，真的，

肯定.?.)”是主語(yǔ)從句最常見(jiàn)的一種結(jié)構(gòu)。例如：

Itisveryclearthathe'sroundandtalllikeatree.

Itisstrangethatithasn'tbeennoticedbefore.真奇怪，它以前沒(méi)有引起注意。

2.Itisv-edthat...=sb/sthistodo

Itissaid(reported/learned/believed/thought/known/told/hoped..…)that...

該句型中的讓仍是形式主語(yǔ)，真正主語(yǔ)是that引導(dǎo)的主語(yǔ)從句；該結(jié)構(gòu)常譯為“據(jù)說(shuō)(據(jù)

報(bào)道，據(jù)悉.??)

ItissaidthathehascometoBeijing..

Itisreportedthatanotherearthsatellitehasbeenputintoorbit.

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(yǔ)氣(should+動(dòng)詞原形)，should可省去.表示出乎

意料，常譯為“竟然”。沒(méi)有這種意義時(shí)，則不用虛擬語(yǔ)氣。例如：

Itis,apitythatsuchathing(should)happeninyourclass.

這種事竟然發(fā)生在你們班上，真是遺憾！

Itisapitythatheisill.他生病了,真遺憾！

四、it作形式賓語(yǔ)

當(dāng)復(fù)合賓語(yǔ)中的賓語(yǔ)是不定式、動(dòng)名詞賓語(yǔ)從句時(shí)，往往把賓語(yǔ)放在它的補(bǔ)足語(yǔ)后面，而用

it作形式賓語(yǔ)，.放在賓語(yǔ)補(bǔ)足語(yǔ)之前。

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

Ithinkitnousearguingwithhim.

我認(rèn)為和他爭(zhēng)吵沒(méi)有用。

IfounditveryinterestingtostudyEnglish.

我發(fā)現(xiàn)學(xué)英語(yǔ)非常有趣。

Hemadeitclearthathewasnotinterestedinthissubject.

他非常清楚地表示他對(duì)那門(mén)學(xué)科不感興趣。

五、用于強(qiáng)調(diào)句型

Itis/was+被強(qiáng)調(diào)部分+that/who...

Itisnotuntil+被強(qiáng)調(diào)部分+that...

ImetTomintheparkyesterday

1）ItwasIwhometTomintheparkyesterday.

2）ItwasTomwhoImetintheparkyesterday.

3）ItwasintheparkthatImetTomyesterday.

4）ItwasyesterdaythatImetTominthepark.

Itwasfiveo'clock_whenIgothome.

Itwasatfiveo'clock_thatIgothome.

Itwasshewho/thathadbeenwrong.是她錯(cuò)了。（主語(yǔ)）

Itwasthegirlwhom/thatImetjustnow.我剛才遇見(jiàn)的就是這個(gè)女孩。（賓語(yǔ)）

ItwasTomtowhomtheteacherhadtalked.老師與其談話的那個(gè)人是湯姆。（介詞賓語(yǔ)）

ItwasonMondaynightthatallthishappened.所有這一切就是在星期一的晚上發(fā)生的。（狀

語(yǔ)）

Itisnotuntil+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(yǔ)，譯成漢語(yǔ)“直到……才……”，可以說(shuō)是not...

until...的強(qiáng)調(diào)形式。例如：

Itwasnotuntilshetookof.fherdarkglassesthatIrealizedshewasafamousfilmstar.=Notuntil

shetookoffherdarkglassesdidIrealizeshewasafamousfilmstar.=Ididn'trealizeshewasa

famousfilmstaruntilshetookoffherdarkglasses.

六、it常用的固定搭配

1.makeit

ICshardtomakeittothetopinshowbusiness.

(2)在口語(yǔ)中相，當(dāng)于fixthedatefor,表示“約定好時(shí)間”

2.it作形式賓語(yǔ)的特殊用法。某些及物動(dòng)詞或短語(yǔ)不能加賓語(yǔ)從句，此時(shí)須先用it作

形式賓語(yǔ),然后接賓語(yǔ)從句。此種用法常用于like,dislike,hate,appreciate,dependon,

seeto等后。如：

Ihateitwhenpeopletalkwiththeirmouthsfull.

Youmay.dependonitthattheywillsupportyou.

I'llappreciateitifyouclosethedoorforme.

Ilikeitintheautumnwhentheweatherisclearandbright.

It'stimeforustogotobed.

It,s(about/high)timethatwewent/shouldgotobed.

注意：It's(about/high)timethat句型中，謂語(yǔ)動(dòng)詞須用虛擬語(yǔ)氣，即用動(dòng)詞的過(guò)去式或
