Your wife wont

2、like it此時要注意與其他代詞如that， one， those, this, another等的區(qū)別： 1.I hear you bought a new bike， I want to buy _ ， too.此處應(yīng)填one，因為這里我并不是要買你的車，而是一輛新車，one a new bike。 2。I have bought a new bike, but I still want to buy _ 。此處應(yīng)填another。我已有了一輛，再買另一輛。another another new bike。 3.We see him when we come to town， but _

9、00年他還在上大學的時候.指代上文中提到的事情用that； it可以指時間、天氣、距離等概念.考向二 作形式主語，替代不定式、ing形式或主語從句（一） 作形式主語替代主語從句1。It is clear ( 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一種結(jié)構(gòu)。 It is very clear that hes round and tall like a tree。 = That hes round and tall like a tree

10、 is very clear。 It is important ( necessary， right， strange， natural。.） that .。 該句型和上一個同屬一個句型；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。 It is important that we （should） learn English well。 It is necessary that he （should） remember these words。 2. It is said (reported/ lea

11、rned/believed/thought/known/told/hoped。.。.。) 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)報道，據(jù)悉）。 It is said that he has come to Beijing。 It is reported that another earth satellite has been put into orbit. 該句型?？梢赞D(zhuǎn)換成含有賓語從句的復(fù)合句或者含有不定式作主補的簡單句。例如: Its said that Tom has come back from abroad.Peop

12、le say that Tom has come back from abroad.He is said to have come back from abroad.It is suggested ( ordered /demanded/insisted/commanded。. ) that 。. 該句型和上一個同屬一個句型，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）,should 可以省；常譯為據(jù)建議；有命令。） It is suggested that the meeting ( should ） be put off. It

13、was ordered that we （ should ) arrive there in two hours. 3。It is a pity ( a shame /an honour/a good thing/a fact，/a surprise/. ) that .。. 該句型中，that后的從句一般用虛擬語氣（should + 動詞原形），should可省去.表示出乎意料，常譯為竟然.沒有這種意義時，則不用虛擬語氣。It is a pity that such a thing ( should ） happen in your class。 這種事竟然發(fā)生在你們班上，真是遺憾！ It

14、is a pity that he is ill。 他生病了,真遺憾！ 4. It happens （seems, looks， appears ） that.。. 該句型中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。It happened （ so happened ） that he met his teacher in the street. 碰巧It seems that he enjoys pop songs very much.看來他非常喜歡流行歌曲。該句型可轉(zhuǎn)換成含不定式的簡單句。如上述兩句可分別轉(zhuǎn)換為：He happened

15、to meet his teacher in the street。He seems to enjoy pop songs very much.5。it代替連接代詞或連接副詞引導(dǎo)的從句作形式主語 (1）It is known（not decided，not made clear，found out，discussed，being discussed,being considered，a question，uncertain等)連接代詞或連接副詞引導(dǎo)的從句。 It is still a question when we shall have our sports meet。 我們將什么時候舉行運

16、動會還是一個問題. It is uncertain whether he can attend this conference or not。 他能否來開會還不能確定。 （2）It doesnt matter（Its no wonder；It doesnt make too much difference等）連接代詞或連接副詞引導(dǎo)的從句。 It doesnt matter whether we go together or separately。我們一起去還是分開去都可以。 It is no wonder why he came here too late.他為什么來這么晚不足為怪(二）作形式

17、主語替代不定式。常見的句型有：1。 . It is kind ( of sb. ) to do sth。 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引起,主句中的形容詞必須是能表示邏輯主語特征的形容詞。 常見的有: bad， brave , careless， clever， cruel， foolish， good (好心的）， honest ， horrible, kind , lazy, modest, naughty, nice（有教養(yǎng)的）， polite， rude, silly, stupid ， wise， wrong(錯誤的)等。 這個句型可以改寫為：sb。

18、 is kind to do sth. . It is kind of you to say so。 = You are kind to say so. It is necessary （ for sb. ） to do sth. 該句型與上一個同屬一個句型，如果不定式的邏輯主語是由for引起,主句中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, rare， imp

19、ossible， pleasant等。 =在中的形容詞作表語可以用從句改寫， 如： It is important for her to come to the party。 = It is important that she (should ） come to the party。 2.It takes sb。 .。 to do sth. 該句型中的不定式是真正的主語，it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. It took thousands of people many years to build the Great Wall。 (三） 作形式主語替代ing形式I

20、t is no good / no use/useless doing sth。 該句型中的真正主語是動名詞短語。It is no good learning English without speaking English。 Its useless trying to argue with Shylock.考向四 作形式賓語，代替不定式、ing形式、賓語從句。1。We think it important to learn a foreign language. 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6123結(jié)構(gòu). 6指主句中常用的動詞:think， believe， ma

21、ke， find, consider, feel； 1指的是形式賓語it；2指的是賓補的兩種形式：形容詞或名詞； 3指的是真正賓語的三種形式：不定式短語，動名詞短語或that等引導(dǎo)的賓語從句。 We think it our duty to clean our classroom every day。 They found it difficult that they would finish their work in two days.The professor thinks it no good reading without understanding。The Internet mak

22、es it easier for companies to keep in touch with customers。1。（2019新課標III卷語法填空）On our way to the house，it was raining _so_ hard that we couldnt help wondering how long it would take _62_ (get)there.【答案】to get【解析】句意:我們?nèi)滩蛔∠胫肋€要多久才能到那里.該句中考查了固定用法:It takes time to do sth.:花時間做某事，該句式中it作形式主語,time做賓語，使用不定式

23、作真正的主語。而句中只是在對賓語時間，用how long 對其進行提問，不影響不定式的使用，故答案為to get?！久麕燑c睛】此題看似考查非謂語動詞,實際也是考查it作形式主語.2.Susan made_ clear to me that she wished to make a new life for herself。 A。 that B. this C。 it D. her【答案】C【解析】這是一個賓語從句，make的賓語是that引導(dǎo)的句子，在本句中用it做形式賓語代指that引導(dǎo)的賓語從句.句意為：Susan向我表明她希望能過上新的生活.故答案選C。3. As the busiest

24、 woman in Norton， she made_ her duty to look after all the other peoples affairs in that town。A。 this B. that C.one D.it【答案】D【解析】it作形式賓語, to look after all the other peoples affairs in that town作真正的賓語.不定式短語作賓語時， 需移置賓語補語之后， 在原來賓語的位置上用引導(dǎo)詞it作形式賓語， 構(gòu)成 make + it + 形容詞或名詞+不定式短語結(jié)構(gòu)， 從而使句子保持平衡。2. 在like, disl

25、ike, hate, love， take, appreciate， depend on， see to（處理），insist on，help等動詞后，形式賓語it后可直接跟賓語從句。此時，it表模糊概念，指代后面所敘述的內(nèi)容。You may depend on it that I shall always support you。I hate it when people laugh at the disabled.I will appreciate it if you can help me with my English。1。Id appreciate _ if you could le

26、t me know in advance whether or not you will come。A。 it B。 you C。 one D。 this【答案】A 【解析】考查代詞辨析及語境理解。appreciate后跟接if或when從句時，其后不直接跟if或when引導(dǎo)的從句，若語義上需要接這類從句，需借助it。故選A。2.How would you like if you were watching your favorite TV program and someone came into the room and just shut it off without asking yo

27、u？A. them B. one C. those D。 it【答案】D【解析】句意：當你正在看一個你喜歡的節(jié)目時，突然有個人進來，一聲不吭地關(guān)掉電視，你會怎么想？It作形式賓語，指代If后面的句子。該句涉及到了一個疑問句，一個條件狀語從句(if）和兩個并列句(and)。這當時應(yīng)該先把它轉(zhuǎn)化為陳述句you would like_分析句子結(jié)構(gòu)知道like之后缺少一個賓語，需要一個賓格代詞充當，所以答案選it?？枷蛭錳t的重要句型 1。強調(diào)句 It is/was + 被強調(diào)部分 + that/who 。. 該句型是強調(diào)句型。將被強調(diào)的部分放在前面,其它部分置于that之后，被強調(diào)部分可以是主語，賓

28、語,表語或狀語，強調(diào)的主語如果是人，that可以由who換用。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)句型與其它從句的方法. It was about 600 years ago that the first clock with a face and an hour hand was made. It was they that （who ) cleaned the classroom yesterday. It was in the street that I met her father。 It was yesterday that I met her in t

29、he street。It is you that /who are wrong.I think it was Jack said this.（其中省略了who 或that)What is it you want me to do？(it 后省略了that)It is not until + 被強調(diào)部分 + that 。 該句型也是強調(diào)句型。主要用于強凋時間狀語，譯成漢語直到才，可以說是 not . until 。. 的強調(diào)形式。 It was not until she took off her dark glasses that I realized she was a famous fil

30、m star。 = Not until she took off her dark glasses did I realize she was a famous film star. = I didnt realize she was a famous film star until she took off her dark glasses. 強調(diào)句型的兩種變形形式：一般疑問句形式:Is/Wasitthat?特殊疑問句形式：Who/Whom/When/When等+is/wasitthat？1）Wasitin1979_theAmericanastronautsucceeded_landingo

31、nthemoon？A。when;onB.that;onC.when；inD。that；in（Key:D)2）Was_thatIsawlastnightattheconcert?

32、。A。 itB。 thatC. thisD。 which【答案】A【解析】It is+被強調(diào)部分+that+其他， 強調(diào)句可去掉it is與that還原句子。本句相當于.。， but I object to how she does it。被強調(diào)部分是賓語從句， 因此, 用it引導(dǎo)該句式.2.It be的適當形式時間 whenclause 這個句型中，it指時間，而且表示時間的詞語前沒有介詞（時間一般為具體時間）。主句中的謂語動詞和從句中的謂語動詞在時態(tài)上一般是一致的,主句是will be，when從句用一般現(xiàn)在時代替一般將來時。常譯為當?shù)臅r候，是例如： It was already 8ocl

33、ock when we got home。 It will be midnight when they get there。Itwasfiveoclockintheafternoon_theyclimbeduptothetopofthemountain。Itwasatfiveoclockintheafternoon_theyclimbeduptothetopofthemountain.A. sinceB. whenC。 thatD。 until 3.It is/has been一段時間 since-clause 這個句型表示從since從句謂語動作發(fā)生以后到現(xiàn)在或過去所經(jīng)過的一段時間，意為自從

34、以來已多久了since 從句后用一般過去時，例如： It ishas been three years since his father passed away.他父親去逝已經(jīng)有三年了。 It is/has been fifteen years since she left Shanghai。她離開上海已經(jīng)15年了4。 It is time ( about time ，high time ) that . 該句型中that 后的從句應(yīng)該用虛擬語氣,常用一般過去時態(tài)表示虛擬.It is time that children went to bed。 It is time you bought a

35、 new car.It is (high ） time you made up your mind。It is the first （ second . ) time that .。. 該句型要和上一個句型區(qū)別開來,該句型中的 that 從句不用虛擬語氣，而用完成時態(tài)，。至于用什么完成時態(tài),由主句的謂語動詞的時態(tài)決定。如果是一般現(xiàn)在時，后面從句用現(xiàn)在完成時態(tài)；如果是一般過去時，后面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。 It is the first time I have been here。 = This is the fir

36、st time I have been here。It was the fifth time（that）I had paid a friendly visit to Africa。5。It be的適當形式一段時間beforeclause 這個句型中的時間一般為表示一段時間的詞語（如：long,years，months，weeks,days , hours，minutes)，主句中的謂語動詞用肯定式，意為過多長時間才。主句的謂語動詞是否定式時，意為沒過多長時間就。主句的時態(tài)可用過去時was或?qū)頃r will be；用was時，before從句的動詞用一般過去時;用will be時，before從

It looks ( seems ) as if .。 該句型中it無意義, as if 引導(dǎo)
