1.Itis+被強調(diào)部分+that

該句型是強調(diào)句型，將被強調(diào)的放在前面，其他部分置于之后，強調(diào)的主語如果是人，可以用來替換，如果把這種句型結(jié)構(gòu)劃掉后，應(yīng)該是一個完整無缺的句子，這也是判斷強調(diào)句型與其他從句的方法。

Itwastheythat(who)cleanedtheclassroomyesterday.ItwasinthestreetthatImetherfather.

Itwaswithgreatjoy___hereceivedthenewsthathislostdaughterhadbeenfound.(2004福建)

A.becauseB.whichC.sinceD.that(D)

2.Itisnotuntil+被強調(diào)的部分+that

該句型譯成漢語“直到……才”，可以說是的強調(diào)形式。ItwasnotuntilshetookoffherdarkglassesthatIrealizedshewasafilmstar.=NotuntilshetookoffherdarkglassesdidIrealizeshewasafilmstar.=Ididn’trealizeshewasafamousfilmstaruntilshetookoffherdarkglasses.

Itwas___backhomeaftertheexperiment.(2004湖北)

A.notuntilmidnightdidhego

B.untilmidnightthathedidn’tgo

C.notuntilmidnightthathewent

D.untilmidnightwhenhedidn’tgo(C)

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

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、肯定）”是主語從句最常見的結(jié)構(gòu)。

Itisveryclearthathe’sroundandtalllikeatree.

=Thathe’sroundandtalllikeatreeisveryclear.

4.Itisimportant(necessary,right,strange,natural…)that…

該句型和上一句同屬一個句型。由于主句中的形容詞不同，that后的從句中要用虛擬語氣（should+動詞原形）should可以省去。建議記住該句型中的形容詞。

Itisimportantthatwe(should)learnEnglishwell.

Itisnecessarythathe(should)rememberthesewords.

5.Itissaid(reported,learned…)that…

該句型中的it仍是形式主語，真正的主語是that引導(dǎo)的主語從句。該結(jié)構(gòu)常譯為“據(jù)說（據(jù)報道，據(jù)悉……）

ItissaidthathehascometoBeijing.

Itisreportedthatanotherearthsatellitehasbeenputintoorbit.

6.Itissuggested(ordered…)that…

該句型和上一句屬一個句型。主句中的過去分詞是表示請求、建議、命令等詞時，that后的從句要用虛擬語氣（should+動詞原形）?？梢允÷裕Ｗg為“據(jù)建議；有命令……”

Itissuggestedthatthemeeting(should)beputoff.

Itwasorderedthatwe(should)arrivethereintwohours.

7.Itisapity(ashame…)that…

在該句型中，that后的從句一般用虛擬語氣（should+動詞原形），should可以省去，表示出乎意料，常譯為“竟然”。沒有這種意義時，則不用虛擬語氣。

Itisapitythatsuchathing(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！

8.Itistime(abouttime,hightime)that…

該句型中that后的從句應(yīng)該用虛擬語氣，值得注意的是：常用過去時態(tài)表示虛擬，有時也用should+動詞原形，should不能省。常譯為“是（正是）……的時候……”

Itistimethatchildrenshouldgotobed.

=Itistimethatchildrenwenttobed.

9.Itisthefirst(second,…)timethat…

該句型應(yīng)和上一個句型區(qū)別開來。該句型中不用虛擬語氣，而用完成時態(tài)。至于用哪種完成時態(tài)，由主句的謂語動詞的時態(tài)來決定。如果是一般現(xiàn)在時，從句用現(xiàn)在完成時態(tài)；如果是一般過去時，從句則用過去完成時態(tài)。該結(jié)構(gòu)中that可以省去；it有時用this替換，常譯為“是第一（二,…）次…”。10.Itis…since…

該句型主要用作處理瞬間動詞的完成時，要和表示一段時間的時間狀語連用。主句中是時間作表語，其時態(tài)是現(xiàn)在時和完成時，引導(dǎo)的從句通常是一般過去時態(tài)，而且是瞬間動詞。如果主句是一般過去時，從句則用過去完成時。

Itis(hasbeen)5yearssincehisfatherdied.

Itisalmostfiveyears___wesaweachotherlasttime.(2005北京)

A.beforeB.sinceC.afterD.when(B)

11.Itis…when…

該句型中的when引導(dǎo)的是一個時間狀語從句，主句中的it指時間，表語由具體的時間充當(dāng)。常譯為“當(dāng)……的時候，是……”

Itwas5o’clockwhenhecamehere.

12.Itbe…before…

該句型主句中的it指時間，主句中的時態(tài)常是一般將來時或過去時兩種時態(tài)，主句中的表語多是long,notlong,3days,2weeks等表示時間段的詞和短語。常譯為“…之后才”，“沒過……就……”

Itwas3daysbeforehewenttoBeijing.

Itwillnotbelongbeforehefinisheshisjob.

13.Ithappens(seems,looks,appears)that…

該句型中的it是形式主語，that引導(dǎo)的是主語從句，主句中的happen,seem等詞是不及物動詞。

Ithappened(sohappened)thathemethisteacherinthestreet.(碰巧……)

Itseemsthathewillbebackinafewdays.(看來……)

TheForeignMinistersaid,“___ourhopethatthetwosideswillworktowardspeace.”(2004北京)

A.ThisisB.ThereisC.ThatisD.Itis(D)

14.Ittakessb…todosth.

該句型中的不定式是真正的主語，是形式主語，句型中的直接賓語是時間。常譯為“做……要花費某人……”

IttookthousandsofpeoplemanyyearstobuildtheGreatWall.

15．Itisnogood(use)doingsth.

該句型中的真正主語是動名詞短語，主句中的表語可以是nogood(notanygood),nouse(notanyuse).

ItisnogoodlearningEnglishwithoutspeakingEnglish.

16.Itdoesn’tmatterwhether…

該句型中的引導(dǎo)的從句是真正的主語，該句型譯為“不論（是否）……沒關(guān)系……

Itdoesn’tmatterwhethertheyareold.

17．Itiskind(ofsb)todosth.

該句型中的不定式短語是真正主語，如果不定式的邏輯主語是由of引出，主句中的形容詞必須是能表示邏輯主語的形容詞。常見的有：bad,brave,careless,clever,cruel,foolishgood(好心的),honest,horrible,kind,lazy,modest,naughty,nice(有教養(yǎng)的),polite,rude,silly,stupid,wise,wrong等。這個句型可以改寫為sb.iskindtodosth.

Itiskindofyoutostayso=Youarekindtosayso.

18.Itisnecessary(forsb)todosth

該句型與上一句統(tǒng)屬一個句型。如果不定式的邏輯主語是由for引出的，主句的形容詞通常是表示重要性，緊迫性，頻繁程度，難易，安全等情況的形容詞。常見的形容詞有：

Important,necessary,natural,easy,safe,common,,normal,hard,difficult,dangerous,unusual,grape,impossible,pleasant.等。

Itisimportantforhertocometotheparty.=Itisimportantthatshe(should)cometotheparty.

19.Itlooks(seems)asif…

該句型中it無意義。Asif引導(dǎo)一個狀語從句，常譯為：“看起來好像……”如果與事實不相符合，則用虛擬語氣。

Itlooksasifheisill.（真的病了）

Itlooksasifhewasill.（事實上沒有生病）

Itseemedasifhewasdying.

20.Wethinkitimportanttolearnaforeignlanguage.

該句型中的it作形式賓語。為了記憶方便我們可稱該句型為“7123結(jié)構(gòu)”

7指主句中的常用的動詞：think,believe,make,find,consider,feel,take.
