4、er, or he will be angry.Q: What does the woman suggest that the man should do?解析 此題屬于推理題。題目詢問(wèn)這位女士建議男士怎樣做。根據(jù)女士的話，男士不能只給簡(jiǎn)買禮物，否則簡(jiǎn)的弟弟會(huì)不高興的，可知應(yīng)選A項(xiàng)(給簡(jiǎn)和她的弟弟都送禮物)。避錯(cuò)指南 選項(xiàng)B(不要生氣)顯然不合題意。選項(xiàng) C(送禮物給簡(jiǎn)的弟弟)和選項(xiàng)D(送禮物給簡(jiǎn))這都不是女士的本意，她強(qiáng)調(diào)的是不能只給簡(jiǎn)禮物，而不給她弟弟，因此任何表示只給一個(gè)人禮物的說(shuō)法都不是女士本意的真實(shí)反，所以均不正確。2.A.He has bought a sweater in tha

5、t shop.B.The sweaters ale ugly.C.She cant buy a suitable sweater in that shop.D.The shop is closed.答案:C聽(tīng)力原文W: I want to buy a sweater in that shop.M: I have been there before, and I dont think the styles suit you.Q: What does the man mean?解析 此題屬于推理題。題目詢問(wèn)這位男士的話是何意。由他的話“我認(rèn)為那里的款式不適合你”可以看出選項(xiàng)C(這位女士不可能在那家

6、商店買到合適的毛衣)為正確答案。避錯(cuò)指南 選項(xiàng)A(男士已在那家商店買了一件毛衣)對(duì)話中并未提及，男士只是說(shuō)曾去過(guò)那里，并未說(shuō)是否購(gòu)買過(guò)毛衣。選項(xiàng)B(毛衣很難看)男士只是說(shuō)毛衣的款式不適合這位女士，并未評(píng)價(jià)它們是否好看。選項(xiàng)D(商店關(guān)門)對(duì)話中根本未提及，因此是錯(cuò)誤選項(xiàng)。3.A.She went to the airport.B.She was busy on her assignment.C.She went to watch a movie.D.She went to see her friend.答案:A聽(tīng)力原文M: You look tired. Where did you go las

7、t night?W: I planned to watch a film,but I went to meet my friend at the airport.Q: What did the woman do?解析 此題屬于推理題。題目詢問(wèn)女士做了什么事情。根據(jù)女士的話“但是我去機(jī)場(chǎng)接朋友去了?！北苠e(cuò)指南 女士一開(kāi)始說(shuō)“I planned to watch a film, but .”，其中的planned和but兩個(gè)詞表示她原來(lái)計(jì)劃去看電影，但實(shí)際上沒(méi)能去成，因此可以排除去看電影了，故選項(xiàng)C(去看電影)不符合題目要求。對(duì)話中并未提及選項(xiàng)B(她忙于功課)和選項(xiàng)D(去看朋友了)兩項(xiàng)的內(nèi)容，因此

8、均為錯(cuò)誤，可予以排除。4.A.Buy another kind of coffee.B.Buy another cup of coffee.C.Stop buying this coffee.D.Buy a new coffee machine.答案:D聽(tīng)力原文W: We ought to stop buying this kind of coffee. It always tastes terrible.M: Maybe we shall get a new coffee machine instead.Q: What does the man want to do?解析 題目詢問(wèn)男士想干什

9、么根據(jù)男士的話“也許我們應(yīng)該一臺(tái)新的咖啡機(jī)”可以推知選項(xiàng)D(買個(gè)新的咖啡機(jī))為正確答案。避錯(cuò)指南 選項(xiàng)A(買其他咖啡)和選項(xiàng)B(再買一杯咖啡)兩項(xiàng)的內(nèi)容對(duì)話中并未提及，可首先予以排除。從對(duì)話中女士說(shuō)的“我們不應(yīng)該再買這種咖啡”可知不現(xiàn)購(gòu)買這種咖啡其實(shí)是女士的建議，因此選項(xiàng)C (不再購(gòu)買這種咖啡)不符合題意，為錯(cuò)誤選項(xiàng)。5.A.Two.B.Five.C.Three.D.Four.答案:A聽(tīng)力原文M: Henry has four classes on Wednesday and Peter has three.W: I only have two, but I have five on Thur

10、sday.Q: How many classes does the woman have on Wednesday?解析 題目詢問(wèn)女士周三有幾節(jié)課。我們可以由I only have two .(我只有兩節(jié)課)一句可以知道女士有一天有兩節(jié)課，耐用女士雖然沒(méi)有說(shuō)這兩節(jié)課什么時(shí)間上的，但是根據(jù)前面說(shuō)的都是周三的安排可以判斷她說(shuō)的也是周三的課程安排，因此選項(xiàng)A為正確答案。避錯(cuò)指南 解答此題只需聽(tīng)清楚題目問(wèn)的是誰(shuí)，就不會(huì)錯(cuò)選B項(xiàng)、C項(xiàng)或D項(xiàng)。當(dāng)然這要求在聽(tīng)原文時(shí)把每一個(gè)人的上課情況作簡(jiǎn)單記錄，然后針對(duì)題目做出正確選擇。Section B Directions: This section is to te

He _ the train if he hadnt been stack in traffic jam on the way to the railway station.A.couldnt missB.wouldnt have missedC.m

31、ustnt have missedD.shouldnt miss答案:B解析 本題考查的是虛擬語(yǔ)氣。由if引導(dǎo)的虛擬條件句，若表示與現(xiàn)在事實(shí)相反的假設(shè)，從句謂語(yǔ)用動(dòng)詞過(guò)去 式，主句謂語(yǔ)用would/could/might+動(dòng)詞原形。如：I would certainly go if I had the time(如果有時(shí)間，我肯定去。)：若表示與過(guò)去事實(shí)相反的假?zèng)]，從句謂語(yǔ)用had + done的形式，主句謂語(yǔ)是would/could/might + have done的形式；若表示與將來(lái)事實(shí)相反的假設(shè)，從句謂晤為動(dòng)詞過(guò)去式或were + to do，主句是would/could/might+

32、動(dòng)詞原形。例如：If I opened the door, what would happen?(如果我打開(kāi)這扇門會(huì)怎樣?)故選項(xiàng)B為正確答案。避錯(cuò)指南 選項(xiàng)A的形式用于表示與將來(lái)事實(shí)相反的假設(shè)；選項(xiàng)C的錯(cuò)誤在于一般不用must來(lái)表示虛擬語(yǔ)氣；D項(xiàng)含有責(zé)備的語(yǔ)氣，表示禁止。問(wèn)題:2. _ Cathy lives is unknown to everyone.A.ThatC.WhichB.WhatD.Where答案:D本題考點(diǎn)是從句。本句為疑問(wèn)副詞引導(dǎo)的主語(yǔ)從句。本句大意：凱西住在哪兒，這事誰(shuí)也不知道。問(wèn)題:3. _ , such problems concerning environment

33、protection are not as easy to solve as they look.A.Speak generallyB.To speak generallyC.Generally speakingD.General speaking答案:C考點(diǎn) 現(xiàn)在分詞用法 句意 一般來(lái)說(shuō)，關(guān)于環(huán)境保護(hù)的這些問(wèn)題并不像看上去那樣容易解決。 解析 有時(shí)現(xiàn)在分詞可用來(lái)表示說(shuō)話人對(duì)所說(shuō)的話的一種態(tài)度，有的已經(jīng)變成了固定短語(yǔ)，可以看 做是一種句子的獨(dú)立成分或插入語(yǔ)。Generally speaking意為“一般來(lái)說(shuō)”。 避錯(cuò) A)Speak gerlerally、B)To speak generall

34、y和D)General speaking不合語(yǔ)法或語(yǔ)言習(xí)慣。 問(wèn)題:4. He _ for her for one hour by the time she arrived there.A.has been waitingB.has waitedC.had been waitingD.waited答案:C解析 本題考查的是主、從句謂語(yǔ)動(dòng)詞時(shí)態(tài)一致的用法。by the time意思是“到什么時(shí)間為止”，從句的時(shí)態(tài)是一般過(guò)去時(shí)，說(shuō)明主句的動(dòng)作應(yīng)該發(fā)生在從句的動(dòng)作之前，且主句中有表示一段時(shí)間的狀語(yǔ)for one hour，所以應(yīng)該用過(guò)去完成進(jìn)行時(shí)，故選項(xiàng)C為正確答案。避錯(cuò)指南 A項(xiàng)和B項(xiàng)的時(shí)態(tài)不能與

35、從句的時(shí)態(tài)保持一致；選項(xiàng)D的過(guò)去時(shí)態(tài)與從句時(shí)態(tài)不協(xié)調(diào)，其動(dòng)作沒(méi)有表示出在從句動(dòng)作(arrive)之前，故排除。問(wèn)題:5. It is natural that ones attitude _ his family changes as he grows older.A.forB.atC.ofD.towards答案:D解析 本題考查的是介詞的搭配。動(dòng)問(wèn)attitude一般與to/towards 搭配，表示“對(duì)的態(tài)度”，故選項(xiàng)D為正確答案。避錯(cuò)指南 A項(xiàng)、B項(xiàng)和C項(xiàng)均不能與名詞attitude搭配，故排除。因此，在平時(shí)的學(xué)習(xí)過(guò)程中多注意名詞和介詞的搭配問(wèn)題。問(wèn)題:6. _ , I would ha

36、ve caught the train.A.Had I arrivedC.Were I arrivedB.Would I arriveD.If I arrive答案:A本題考點(diǎn)是虛擬語(yǔ)氣。此句的主語(yǔ)用的是would+have+過(guò)去分詞，表示與過(guò)去事實(shí)相反，從句中就應(yīng)該用had+過(guò)去分詞。本句大意：要是我已經(jīng)到了那兒的話，我就能趕上火車了。問(wèn)題:7. I can still remember the city _ my mother and I used to live.A.whereC.whichB.in whereD.that答案:A本題考點(diǎn)是從句。句中先行詞為名詞city，where可以引

37、導(dǎo)表地點(diǎn)的定語(yǔ)從句。本句大意：我仍然記得我和媽媽曾經(jīng)居住過(guò)的那個(gè)城市。問(wèn)題:8. _some students are able to find employment after graduation, others will have to return to school and earn an advanced degree.A.SinceB.WhileC.BecauseD.If答案:B詳解 本題考查對(duì)句意及連詞意義的掌握。這里只有連詞while可以表示轉(zhuǎn)折含義，故答案選B。問(wèn)題:9. _ from space, our earth, with water covering 70% of

38、 its surface, appears as a blue planet.A.SeeingB.To be seenC.SeenD.Having seen答案:C這里當(dāng)主語(yǔ)與謂語(yǔ)動(dòng)詞see之間不是主動(dòng)的關(guān)系時(shí)，我們就應(yīng)用過(guò)去分詞來(lái)表示被動(dòng)。反之則用現(xiàn)在分詞。例如：The old man was fast asleep，holding a book in his hand，老人很快睡著了，手里還拿著一本書(shū)(現(xiàn)在分詞作伴隨狀語(yǔ))。Seen in this light，the matter is not as serious as people generally suppose.如從這方面看，這

39、件事并不像人們普遍推測(cè)的那樣嚴(yán)重(過(guò)去分詞作條件狀語(yǔ))。see，feel等這類感官動(dòng)詞一般不用進(jìn)行體即seeing，feeling來(lái)表示正在進(jìn)行的動(dòng)作。故沒(méi)有see的現(xiàn)在分詞形式作狀語(yǔ)的情況。正確答案即為C項(xiàng)。問(wèn)題:10. The name of the film was on the _ of my tongue, but I just couldnt recall it.A.endB.pointC.tipD.top答案:Chave (sth.) on the tip of ones tongue：話到嘴邊(卻想不起來(lái)了)Section B Directions: There are 10

40、incomplete statements here. You should fill in each blank with the proper form of the word given in brackets. Write the word or words in the corresponding space on the Answer Sheet. 問(wèn)題:1. January 1st, 1937, is the historic date when Britain (join) _ the Common Market.答案:joined解析 在由關(guān)系副詞when引導(dǎo)的定語(yǔ)從句中從句

41、的時(shí)態(tài)應(yīng)和表示時(shí)間的先行詞保持一致。在本句中， the historic date指的是January 1st，1937，這是個(gè)表示過(guò)去時(shí)間的狀語(yǔ)，所以用一般過(guò)去時(shí)。問(wèn)題:2. Neither you nor I (be) able to answer Mr. Lis question.答案:am考點(diǎn) 主謂一致 解析 當(dāng)Neither.nor.引導(dǎo)的部分作主語(yǔ)時(shí)，根據(jù)就近原則，句子的謂語(yǔ)由nor后面的部分決定。本句中沒(méi)有明顯的表示時(shí)間的詞匯，最好用一般現(xiàn)在時(shí)。 問(wèn)題:3. It is argued whether people _ (score) lower than 80 should be

42、 registered unintelligent.答案: scoring問(wèn)題:4. My house is full of dust because the old house just opposite _ (pull) down.答案:is being pulled根據(jù)前半句知道時(shí)態(tài)為現(xiàn)在時(shí)，而后半句有被動(dòng)的意思，更應(yīng)注意的是：時(shí)態(tài)是現(xiàn)在進(jìn)行時(shí)。問(wèn)題:5. Id rather you (attend) _ the meeting now.答案:attendedwould rather +(not) do sth寧愿做(不做)”。would rather sb. did sth意為“寧愿某

The best way to know about the world affairs and local news is to read newspaper (regular) _.答案:regularly解析 本句中read是謂語(yǔ)動(dòng)詞，應(yīng)該用副詞修飾動(dòng)詞，regular的副詞形式為regularly，意為“定期地，有規(guī)律地”。問(wèn)題:7. She rode the bicycle (caution)_as the road

44、 was icy.答案:cautiously答案精解 句意：因?yàn)槁访嬗斜?，所以她小心騎車。該題考查的是詞性轉(zhuǎn)換。根據(jù)題意，此處需要一個(gè)副詞來(lái)修飾ride，而caution的副詞形式是cautiously。問(wèn)題:8. The _ (complex) of its grammatical structure makes this sentence difficult.答案:complexity本題測(cè)試的是詞性轉(zhuǎn)換。全句的意思是：“這個(gè)句子語(yǔ)法結(jié)構(gòu)的復(fù)雜使句子很難?！?ity后綴可以將很多形容詞轉(zhuǎn)換為名詞，表示原來(lái)形容詞的狀態(tài)或是品質(zhì)，如similarsimilarity(相似點(diǎn))，popularp

I would have remained in (ignore) _ if Mathew hadnt explained it to me.答案: ignorance解析 本題考查介詞賓語(yǔ)的用法。in是介詞，后面缺介詞賓語(yǔ)，賓語(yǔ)應(yīng)由名詞或代詞擔(dān)任，但ignore是動(dòng)詞，必須把它轉(zhuǎn)化為名詞ignorance。答題指南 此外，ignore的形容詞形式是ignorant(無(wú)知的)；考生

46、應(yīng)注意區(qū)別使用。問(wèn)題:10. That shy girl is quite (sense)_to other peoples words.答案:sensitive答案精解 句意：那個(gè)害羞的女孩對(duì)別人的話特別敏感。該題考查的是詞性轉(zhuǎn)換。句中需要作表語(yǔ)，故名詞sense轉(zhuǎn)換為形容詞sensitive。Part Reading Comprehension Directions: This part is to test your reading ability.
