Your wife wont like it此時(shí)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?yàn)檫@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 e to town, but _ isnt often.此處填that或it均可。指代前面我們?nèi)コ抢飼r(shí)可以看到他這一情況。 4.My seat is next to _ of the headmaster.此處應(yīng)填that，用來代替名詞seat，thatthe seat。 5.The bikes made this year are better than _ made last years.此處應(yīng)填those或the ones。代替前文的bikes，因其是復(fù)數(shù)概念，故用those或the ones，those the onesthe bikes。 2.也可以指動物Is this your dog？No, it isnt.3用來指代人。說明某人的身份或者做某事的人；指代嬰兒或兒童；在不清楚某人性別時(shí)，也可使用 it，尤其在問答的形式中更為常見。例如： Who is it?

He B. It C. This D. That【答案】B【解析】考查代詞的用法。句意：誰在門外？是送牛奶的。因?yàn)椴恢篱T外的是什么人。故用it指代不清楚的人。故選B。3.If I can help_, I dont like working late into the night.A. so B. that C. it D. them【答案】C 考向二 非人稱代詞itit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：1.指天氣：It is a lovely day, isnt it? It is a bit windy.2.指時(shí)間: It was nearly midnight when she came back. 3.指環(huán)境: It was very quiet in the caf. 4.指距離：It is half an hours walk to the city centre. 5指日期：Whats the date today?

He got his first book published. It turned out to be a bestseller. When was _? _ was in 2000 when he was still in college. A. that; This B. this; It C. it; This D. that; It【答案】D 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 is very clear. It is important ( necessary， right， strange， natural.) that . 該句型和上一個(gè)同屬一個(gè)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/ learned/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(bào)道，據(jù)悉）。 It is said that he has e 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(bǔ)的簡單句。例如： Its said that Tom has e back from abroad.People say that Tom has e back from abroad.He is said to have e back from abroad. It is suggested ( ordered /demanded/insisted/manded. ) that . 該句型和上一個(gè)同屬一個(gè)句型，主句中的過去分詞是表示請求，建議，命令等詞時(shí)，that 后的從句要用虛擬語氣（should + 動詞原形），should 可以??；常譯為據(jù)建議；有命令.） It is suggested that the meeting ( should ) be put off. It 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(shí)，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 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 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(shí)候舉行運(yùn)動會還是一個(gè)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(gè)句型可以改寫為：sb. 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(gè)同屬一個(gè)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， mon， normal， hard， difficult， dangerous， unusual， rare， impossible， 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 e to the party. = It is important that she (should ) e 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(shí)間，常譯為做要花費(fèi)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It 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, make, find, consider, feel； 1指的是形式賓語it；2指的是賓補(bǔ)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 makes it easier for panies to keep in touch with customers. 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(gè)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。2. As the busiest 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 2. 在like, dislike, 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(shí)，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. 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 you?A. them B. one C. those D. it【答案】D【解析】句意：當(dāng)你正在看一個(gè)你喜歡的節(jié)目時(shí)，突然有個(gè)人進(jìn)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(gè)疑問句，一個(gè)條件狀語從句（if）和兩個(gè)并列句(and)。這當(dāng)時(shí)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(gè)賓語，需要一個(gè)賓格代詞充當(dāng)，所以答案選it?？枷蛭錳t的重要句型 1.強(qiáng)調(diào)句 It is/was + 被強(qiáng)調(diào)部分 + that/who . 該句型是強(qiáng)調(diào)句型。將被強(qiáng)調(diào)的部分放在前面，其它部分置于that之后，被強(qiáng)調(diào)部分可以是主語，賓語，表語或狀語，強(qiáng)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(gè)完整無缺的句子；這也是判斷強(qiáng)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 the 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(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。 It was not until she took off her dark glasses that I realized she was a famous film 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(qiáng)調(diào)句型的兩種變形形式：一般疑問句形式：Is/ Was it that? 特殊疑問句形式：Who/ Whom /When/ When 等 + is/ was it that ?1)Was it in 1979 _ the American astronaut succeeded _ landing on the moon? A. when; on B. that; on C. when; in D. that; in (Key: D)2）Was _ that I saw last night at the concert? A. it you B. not you C. you D. that yourself (Key: A)3）Who was it that you met in the street yesterday? 昨天你在街上遇到的是誰？Where was it that you met Jack yesterday? 你昨天是在哪里遇到杰克的？ I dont mind her criticizing me, butis how she does it that I object to.A. itB. thatC. thisD. which【答案】A 2.It be的適當(dāng)形式時(shí)間 when-clause 這個(gè)句型中，it指時(shí)間，而且表示時(shí)間的詞語前沒有介詞（時(shí)間一般為具體時(shí)間）。主句中的謂語動詞和從句中的謂語動詞在時(shí)態(tài)上一般是一致的，主句是will be，when從句用一般現(xiàn)在時(shí)代替一般將來時(shí)。常譯為當(dāng)?shù)臅r(shí)候，是例如： It was already 8oclock when we got home. It will be midnight when they get there.It was five oclock in the afternoon _ they climbed up to the top of the mountain.It was at five oclock in the afternoon _ they climbed up to the top of the mountain.A. since B. when C. that D. until 3.It is/has been一段時(shí)間 since-clause 這個(gè)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(shí)間，意為自從以來已多久了since 從句后用一般過去時(shí)，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(shí)態(tài)表示虛擬.It is time that children went to bed. It is time you bought a 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(gè)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(shí)態(tài)，。至于用什么完成時(shí)態(tài)，由主句的謂語動詞的時(shí)態(tài)決定。如果是一般現(xiàn)在時(shí)，后面從句用現(xiàn)在完成時(shí)態(tài)；如果是一般過去時(shí)，后面從句則用過去完成時(shí)態(tài)，該結(jié)構(gòu)中 that 可以省去；it有時(shí)用 this替換.常譯為是第一（二）次。 It is the first time I have been here. = This is the first 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(dāng)形式一段時(shí)間before-clause 這個(gè)句型中的時(shí)間一般為表示一段時(shí)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(shí)間才。主句的謂語動詞是否定式時(shí)，意為沒過多長時(shí)間就。主句的時(shí)態(tài)可用過去時(shí)was或?qū)頃r(shí) will be；用was時(shí)，before從句的動詞用一般過去時(shí)；用will be時(shí)，before從句常用一般現(xiàn)在時(shí)。例如： It was not long before she learned those poems by heart .她沒過多久就背會了那些詩歌。 It was long before the police arrived.過了很久警察才來。It will be hours before he makes a decision.要過好幾個(gè)小時(shí)他才會作出決定。It will not be hours before we meet again.要不了幾個(gè)小時(shí)我們還會再見面的。 6. It looks ( seems ) as if . 該句型中it無意義， as if 引導(dǎo)一個(gè)狀語從句。常譯為看起來好象如果與事實(shí)不相符合，則用虛擬語氣。 It looks as if he is ill.（真的病了） It looks as if he were ill. （沒有生?。?It seemed as if he were dying. 題組一 能力過關(guān)I單項(xiàng)填空1.Young people should be independent, and dont take _for granted that you can depend on your parents when in trouble.A.oneB.itC. thisD. that2.He didnt make _clear when and where the sports meet would be held.A. thisB.itC. thatD.one3.They dislike _when people do not look at the name cards, so remember not to just put them in your pocket without looking.A. thatB. themC.itD. you4.We find _easy to get along with our new teachers here.A. thatB.itC. thisD.不填5.Almost 90% of the most popular video games contain violence, and much of _ is extremely violent.A. whichB.itC. themD. those6.Almost 90% of the most popular video games contain violence, and much of _ is extremely violent.A. whichB.itC. themD. those7.The pop singer is talented and elegant. _ is no surprise that she has so many fans around the world.A.

As usual, I told truth. He said, "Ill be right back." I thought he was another person who thought I talked too , and politely himself.

It had been an difficult day. My heart was hurt and an angel came to treat me kindness.【解析】第一處：workedworking?？疾榉侵^語動詞。根據(jù)語境并分析句子結(jié)構(gòu)可知，句子的謂語動詞為asked，而work與其邏輯主語a young man之間為主謂關(guān)系，故應(yīng)用其現(xiàn)在分詞形式working作后置定語。第二處：truth前加the?？疾楣谠~。tell the truth"說實(shí)話"為固定短語。第三處：manymuch。考查副詞。此處應(yīng)用副詞much修飾動詞talked。第四處：excuseexcused?？疾闀r(shí)態(tài)。此處表示"我以為他是又一個(gè)覺得我話太多的人，于是禮貌地請求離開"。根據(jù)語境及從句中的"and"可知，此處應(yīng)是excused與上文的was并列作從句的謂語動詞，主語均為he，故應(yīng)用一般過去時(shí)。第五處：whilewhen?？疾檫B詞。此處表示"我正要出去，這時(shí)他回來了并遞給我一束(扎得)漂亮的花"。be doing . when.為固定句型，表示"正在做，這時(shí)"。 第八處：teartears。考查名詞復(fù)數(shù)。move sb. to tears"使某人感動得落淚"為固定搭配。第九處：extremeextremely?？疾楦痹~。此處應(yīng)用副詞extremely"非常，極其"來修飾形容詞difficult。第十處：forwith?？疾榻樵~。treat sb. with sth."以態(tài)度/方式對待"為固定搭配。題組二 體驗(yàn)真題1.A 【解析】考查代詞辨析及語境理解。appreciate后跟接if或when從句時(shí)，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.B 【解析】這里用it代替時(shí)間last year，其他的選項(xiàng)代詞不能代替時(shí)間。句意：去年平均降雨量18.75cm，是加利福尼亞在1850年成為一個(gè)州以來，去年是最干的一年。故選B。
