(如需獲取本MP3聽力錄音請搜索標(biāo)題名) 1.A.Yes, I was.B.Yes, I would.C.Yes, he did.D.Yes, he was.答案:D解析 Was your brother at home this morning? 解析 本題考查對be動詞引導(dǎo)的一般疑問句的回答。一般疑問句的回答要與問句中的人稱和be動詞(或助動詞)保持一致。句中詢問對方的兄弟是否在家，D)“是的，他在家”是對本句的恰當(dāng)回答。A)與B)的主語不對，回答要與問句的主語your brother在人稱上保持一致，應(yīng)該用he進(jìn)行回答，而不是用I；C)的動詞沒有與問句的was保持一致。 2

4、.A.Many languages.B.Pretty well.C.Four languages.D.With his roommates.答案:C解析 How many foreign languages does Peters wife speak? 解析 本題考查對How many提問的特殊疑問句的回答。本題詢問Peter的妻子會說幾種外語，C)“四種語言”對語言的數(shù)量做出了明確的回答，所以為正確答案。A)“很多種語言”回答沒有針對問題給出確切的數(shù)字，同時也不太符合實際語境；B)“說得很好”和D)“與她的室友一起”都是答非所問。 3.A.By car.B.Yesterday aftern

5、oon.C.In New York.D.For some information.答案:D解析 Why did MrsGreen go to the travel agency? 解析 本題考查對Why提問的特殊疑問句的回答。本句詢問MrsGreen為什么去旅行社，D)“為咨詢一些信息”為正確答案。A)“開車去的”是回答怎么去的；B)“昨天下午”是回答時間；C)“在紐約”是回答地點，所以這三項都不符合問句的回答。 4.A.Yes, please.B.Yes, I prefer tea.C.I like coffee very much.D.Thank you very much.答案:A解析

6、Hi，Susan，would you like a coffee? 解析 本題考查對提出邀請時征求對方意愿的回答。對于這類問題的回答，先要給出明確的Yes或No判斷性的回答，表明自己的意愿，所以A)“好的”是合適的回答。B)“好的，我想喝茶”與詢問的“咖啡”相矛盾；C)“我非常喜歡咖啡”只是單純表示了自己的喜好，并沒有回答現(xiàn)在是否想喝；D)“非常感謝”用于對別人提供的幫助表達(dá)謝意，也不合適。 5.A.No, I dont know.B.Surely not.C.It doesnt matter.D.Dont mention it.答案:B解析 Excuse me，do you mind tur

7、ning down the music a bit? 解析 本題考查對提出請求的一般疑問句的回答。句中問：“對不起，你是否介意把音樂音量調(diào)小一些?”由Do you mind引導(dǎo)的一般疑問句，用Yes回答表示拒絕別人的請求，而用No回答表示不介意別人的提議。所以B)“當(dāng)然不介意”是合適的回答。A)“我不知道”答非所問，顯然不合適；C)“沒關(guān)系”是用來回答道歉的話語；D)“不用謝”是對表示感謝的話語做出的禮貌回答。 Section BDirections: This section is to test your ability to understand short dialogues.

10、生。由此推測Jack是一位雜貨商，D)為正確答案。A)“農(nóng)夫”；B)“工人”和C)“推銷員”都不符合Jack所做的工作描述。2.A.He asked the woman to give a talk on chemistry.B.He persuaded the woman not to take the course.C.He gave a talk to the chemistry class.D.He told the woman it was right to choose chemistry.答案:B解析M：I thought you were planning to take th

11、e chemistry courseW：I was，but my teacher talked me out of it.Q：What did the womens teacher do?解析 語義理解題。本題重點考查詞組talk sbout of sth，意為“勸說某人不要做某事”，所以B)“老師說服了這位女士沒有選擇化學(xué)課”是正確答案。A)“老師讓女士做一個化學(xué)演講”； C)“老師在化學(xué)課上做了一個演講”和D)“老師告訴女士選化學(xué)課是正確的”對話中均未提及。3.A.Stop and take a rest.B.Wait for the rest of the group.C.Keep go

12、ing.D.Rest when she is tired.答案:C解析M：Would you like to stop for a rest now?W：Were almost at the top of the hillQ：What does the woman want to do?解析 語義理解題。男士問女士是否需要停下來休息一會，女士說他們已經(jīng)快要到山頂了。言外之意是不用中途休息，一鼓作氣登上山頂。所以C)“繼續(xù)向上爬”是正確答案。 A)與女士的言外之意正好相反；B)“等等小組的其他人”和D)“她感覺累了再休息”這兩項在對話中均未提及，故排除。4.A.10:30.B.10:45.C.1

13、0:50.D.11:20.答案:D解析W：When is Eric coming?M：Well，its 10:30 nowI think hell come in 50 minutesQ：When will Eric arrive?解析 推理判斷題。本題的解題關(guān)鍵是聽清楚時間11:30和50 minutes，然后推算出Eric到達(dá)的時間。對話中男士說“現(xiàn)在是10:30，Eric會在50分鐘后到達(dá)”，所以據(jù)此推算，Eric應(yīng)該會11:20過來，所以D)為正確答案。其他三項推算的時間都不準(zhǔn)確，故排除。5.A.He is going to call somebody.B.He will join t

14、he woman.C.He isnt going to the cinema.D.He is not interested in the movie.答案:C解析W：Were going to the cinema nowAre you coming?M：Im waiting for a phone callQ：What does the man imply?解析 細(xì)節(jié)推斷題。女士邀請男士一起去看電影，男士說自己正在等一個電話。言外之意是他不能與女士一起去看電影，所以C)正確答案。A)“他要給別人打電話”與對話中“男士正在等電話”內(nèi)容相悖；B)“他會和女士一起去看電影”，與原文意思相反；D)“

15、他對電影不感興趣”，男士只暗示他有事不能與女士一起去看電影，并沒有說他不喜歡看電影，故也排除。Section CDirections: In this section you will hear a recorded short passage.

Every Saturday and Sunday are filled with activities. In the street you can hardly see a man who walks slowl

21、y. They walk very fast. In fact, they are running.解析 前一句說“從兒童時期，美國人就學(xué)會了珍惜時間”，所以接著進(jìn)一步闡述美國小孩是如何重視時間的，他們從小就被教導(dǎo)要按時去做每一件事情。結(jié)合錄音，空格處填入 children符合句意。2.答案:time flies解析 前一句說“當(dāng)他們過得很愉快時”，后一句則是說明愉快的時光總是過得很快。 time flies是一個常用的習(xí)慣表達(dá)，表示時間過得非?？?，通常用于形容愉快的經(jīng)歷。3.答案:everything解析 前面說“時間是金錢，時間是知識”，后面進(jìn)一步總結(jié)說“時間就是一切”。所以結(jié)合錄音，填入

22、everything符合句意。4.答案:spare解析 前面提到美國的工作時間是每天8小時工作制，所以由This is working time(這是工作時間)和空格后的time推知，后文會提到與工作時間相對的完全不同的一種時間。結(jié)合錄音，填入spare可知，此處是說空閑時間。5.答案:fast解析 結(jié)合空格前文說“在大街上，很少可以看到有人在慢慢地走路”，后文說“實際上，他們都在跑”是在對空格所在句做進(jìn)一步解釋，可知空格處是在說人們走得非?？欤f明人們走路的狀態(tài)與slowly完全不同，所以結(jié)合錄音填入副詞fast。Part Vocabulary and StructureDirections

23、:This part is to test your ability to use words and phrases correctly to construct meaningful and grammatically correct sentences. It consists of 2 sections.Section ADirections: There are 10 incomplete statements here. You are required to complete each statement by choosing the appropriate answer fr

24、om the 4 choices marked A), B), C) and D). You should mark the corresponding letter on the Answer Sheet with a single line through the centre.問題:1. He _ this bike for 600 yuan. I thought it was a little expensive.A.paidB.offeredC.spentD.cost答案:B解析 動詞辨析 解析 本題重在考查固定搭配offer sthfor some money，意為“要價多少錢”。

25、 避錯 A)一般用法是pay sbfor money意為“付給”某人多少錢；C)一般搭配是sb spend time or money (in) doing or on stk；D)一般搭配是sthcost sbsome time/money均不符合原句的句子結(jié)構(gòu)。 問題:2. You must explain to us how they succeeded _ the experiment.A.forB.atC.inD.to答案:C解析 介詞辨析 解析 本題主要考查固定搭配succeed in sth，意為“在某方面成功”。 避錯 succeed意為“成功”時，是不及物動詞，后面只能跟介詞

26、in+(doing)sth作賓語，其他介詞都不能與其搭配使用。 問題:3. Their happy voices showed that they were having a _ talk.A.noisyB.seriousC.completeD.friendly答案:D解析 形容詞辨析 解析 由主語happy sound可知，這次談話應(yīng)該進(jìn)行得非常順利和融洽。所以D)“友好的”符合句意。 避錯 A)“吵鬧的”；B)“嚴(yán)肅的”和C)“完整的”，都不符合句子要表達(dá)的友好融洽的談話氛圍。 問題:4. Mr. Hall understands that _ math has been easy for

27、 him, it is not easy for the students.A.althoughB.becauseC.ifD.when答案:A解析 表示轉(zhuǎn)折的連詞辨析 解析 本句是由that引導(dǎo)的賓語從句。由賓語從句中前后兩個分句的easy和not easy可以推斷，句子邏輯關(guān)系應(yīng)該表示轉(zhuǎn)折，所以選擇A)表示“雖然，但是”。 避錯 B)引導(dǎo)原因狀語從句；C)引導(dǎo)條件狀語從句和D)引導(dǎo)時間狀語從句，都不是表示轉(zhuǎn)折含義的連詞。 問題:5. The silence of the library _ only by the sound of pages being turned over. A. ha

28、s been brokenB. was broken C. broke D. breaks 答案:B解析 被動語態(tài) 解析 根據(jù)句意，圖書館的安靜與翻書聲之間應(yīng)該是被動關(guān)系，所以需要用被動語態(tài)。因為本句只是要描述一個事實和狀態(tài)，并沒有要表明這個動作造成的影響，所以不必用完成時，所以B)“一般過去時+被動語態(tài)”為正確答案。 避錯 C)和D)都不符合被動語態(tài)的結(jié)構(gòu)“be+動詞的過去分詞”，所以排除；A)是完成時，本題并沒有要表達(dá)動作對現(xiàn)在造成的影響，故排除。 問題:6. Perhaps we need to clear up these books to make _ for our new stu

29、dents.A.placeB.areaC.wayD.room答案:D解析 固定搭配 解析 本題主要考查固定搭配make room for，意為“為騰地方”。 避錯 A)“地點”；B)“地區(qū)”和C)“道路”，都不能與make和for搭配，構(gòu)成固定短語，同時也不符合句意。 問題:7. Was it because it snowed last night _ you didnt come?A.whenB.thatC.soD.what答案:B解析 強調(diào)句型 解析 本句主要考查強調(diào)句型的固定結(jié)構(gòu)It is/wasthat。一本句是強調(diào)句的一般疑問句式，換成陳述句語序應(yīng)為：It was because

30、it snowed last night that you didnt come該句主要是強調(diào)由because引導(dǎo)的原因狀語從句，that后是主句，表示結(jié)果。 避錯 A)when引導(dǎo)時間狀語從句，與原句中的because連詞重復(fù)使用，同時也不符合句意；C)由于原因中有because出現(xiàn)，so一般不與其同時用在一句中，故很容易排除；D)原句主子結(jié)構(gòu)完整，what無法在句子充當(dāng)任何成分，故也排除。 問題:8. I demand that one of them _ there at once.A.could goB.goesC.must goD.go答案:D解析 虛擬語氣 解析 當(dāng)句中含有sugg

31、est，order，wish，demand等表示建議、命令、希望、要求等含義的動詞時，后面that從句的謂語動詞要用虛擬語氣“(should+)動詞原形”，所以選D)。 避錯 A)，B)和C)都沒有用虛擬語氣，不能滿足demand that句型的要求，故排除。 問題:9. Our plane _ from New York at 6:00 yesterday evening.A.took offB.put offC.flew offD.left off答案:A解析 動詞詞組辨析 解析 本題主要考查與off相關(guān)的動詞詞組的含義。take off在本句中意為“(飛機)起飛”，所以A)符合句意。 避

32、錯 B)“推遲”；C)“突然跑掉”和D)“停止”，均不符合句意，可排除。 問題:10. If youre going to the airport by car, can you give me a _ ?A.liftB.seatC.driveD.hand答案:A解析 固定搭配 解析 本題考查固定搭配give sba lift，意為“讓某人搭車”，符合題意。 避錯 B)和C)的搭配都不成立，故排除；D)give me a hand意為“幫我一下忙”，不符合句意。 Section BDirections: There are also 10 incomplete statements here.

33、 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.問題:1. She has a lot of experience of (chair) _ sports meeting.答案:chairing解析 動名詞形式作賓語 解析 此處空格為介詞of的賓語，其形式應(yīng)該為名詞或動名詞，所以應(yīng)該填入chair的動名詞形式chairing。 問題:2.

34、 The pop stars wife (polite) _ refused the interview.答案:politely解析 詞性轉(zhuǎn)換 解析 refused為句子的謂語動詞，前面可以用副詞來修飾，所以空格填入polite的副詞形式，加-ly后綴即可。 問題:3. Im tired and sleepy. I (go) _ to bed earlier last night.答案:Should have gone解析 虛擬語氣 解析 分析句意，“現(xiàn)在又困又累”說明說話者沒有得到很好的休息，由此可知昨天晚上應(yīng)該睡得很晚。反而言之，“昨天晚上我應(yīng)該早點睡的?！彼裕瑧?yīng)該用與過去事實相反的虛擬

35、語氣“should+have+動詞的過去分同”。 問題:4. My back is so (pain) _ that I cannot stand upright (筆直地) any more.答案:painful解析 詞性轉(zhuǎn)換 解析 is是系動詞，后面可以用形容詞作表語，同時空格前又有so修飾，由此更加確定填入pain的形容詞形式painful。 問題:5. Customers have to fill out forms which (mail) _ to them.答案:are mailed解析 被動語態(tài) 解析 本句有which引導(dǎo)的定語從句，其邏輯主語forms“表格”與mail之間是

36、邏輯上的主動關(guān)系，表格只能是被寄送給顧客的，所以此處用被動語態(tài)。還要注意forms是復(fù)數(shù)形式，被動語態(tài)的be動詞也要用復(fù)數(shù)。結(jié)合主句是一般現(xiàn)在時態(tài)，填入are mailed。 問題:6. On the street, I met an old friend whom I (not see) _ for years.答案:had not seen解析 過去完成時 解析 主句的謂語met是一般過去時，而“多年未見”這個動作應(yīng)該發(fā)生met之前，表示過去的過去；另外句中for years表示一段時間，是完成時的標(biāo)志，所以確定填入過去完成時“had not+動詞的過去分詞”。 問題:7. Accordi

37、ng to some scientific research, smoking will (short) _ a persons life greatly.答案:shorten解析 詞性轉(zhuǎn)換 解析 本句中smoking為主語，名詞性短語a persons life作賓語，情態(tài)動詞will后還缺少動詞原形構(gòu)成句子的謂語，所以將形容詞short后面加后綴-en構(gòu)成動詞形式。 問題:8. The longer the sun shines, (warm) _ the earth is.答案:the warmer解析 形容詞比較級 解析 本題考查常用句型“the+比較級，the+比較級”，表示“越越”

38、。所以空格處填入the warmer。 問題:9. If no one (answer) _ the phone at home, ring me at work.答案:answers解析 主謂一致 解析 本題是一般現(xiàn)在時表示將來的某種情況，主句與從句用一般現(xiàn)在時即可。主句是祈使句，用動詞原形ring，但是從句中的主語是no one，所以從句中的謂語動詞應(yīng)該用第三人稱單數(shù)answers。 問題:10. Would you mind (sit) _ next to me?答案:sitting解析 現(xiàn)在分詞 解析 動詞mind后面一般跟動名詞作賓語，所以填入sit的動名問形式。而sit以輔音結(jié)尾，

39、需要雙寫字母t，所以應(yīng)該填入sitting。 Part Reading ComprehensionDirections:This part is to test your reading ability. There are 5 tasks for you to fulfill. You should read the reading materials carefully and do the tasks as you are instructed.Directions:After reading the following passage, you will find 5 question

40、s or unfinished statements, numbered 36 to 40. For each question or statement there are 4 choices marked A), B), C) and D). You should make the correct choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Is it difficult for you to get up in the morning

41、? Yes? Then Hiroyuki of Japan has a special bed for you. Hiroyukis bed will get you up in the morning! The bed is connected to an alarm clock. First, the alarm clock rings. You have a few minutes to wake up. Next a tape recorder in the bed plays soft music or other pleasant sounds. The tape recorder

42、 in Hiroyukis then says in a sweet voice, Wake up, darling, please. A few minutes later, a second recording plays. The second recording can be loud music or unpleasant sounds. Hiroyuki hears a recording of his boss. His boss shouts, Wake up immediately, or youll be late! If you dont get up after the

43、 second recording, youll be sorry. A mechanical foot is in the bed. The mechanical foot kicks you in the head. Then the bed waits a few more minutes. What! Youre still in bed! Slowly, the tip of the bed rises higher and higher. The foot of the bed goes lower and lower. Finally, the bed is vertical (

44、垂直的). You slide off the bed and onto the floor. You are awake and out of bed. 1. Hiroyuki is _A.a clever bossB.the manager of the companyC.a lazy workerD.the inventor of the bed答案:D解析 細(xì)節(jié)推斷題。根據(jù)文中第一段最后兩句說“日本的Hiroyuki有一張?zhí)厥獾拇?，他的床可以早上叫人起床”，可以得知Hiroyuki是該床的發(fā)明者。 避錯 A)“老板”；B)“經(jīng)理”和C)“工人”與這張?zhí)厥獾拇捕紱]有必然的聯(lián)系。另外，從文

45、中可知這張床就是屬于Hiroyuki一個人的，所以他就是這床的發(fā)明者。 2. The word sorry in the underlined sentence means_.A.sadB.shamefulC.regretfulD.wrong答案:C解析 語義理解題。該題考查sorry在具體語境中的含義。由后文的第三句可以知道，如果第二次鬧鐘響了你還不起床，這種機器的“腳”就會踢你的頭，可見后果比較嚴(yán)重，所以你會后悔，所以C)“后悔的”符合上下文意思。 避錯 A)“傷心的”；B)“可恥的”和D)“錯誤的”，都與上下文語境不符。 3. According to the third paragra

46、ph, the mechanical foot is set _.A.on the top of the bedB.at the foot of the bedC.in the middle of the bedD.under the bed答案:A解析 推理判斷題。由線索詞the mechanical“foot”定位到原文第三段第三句：The mechanical foot kicks you in the head可以推斷，該機械腳最有可能裝在床頭。 避錯 如果所敲打的是人的腳部，那么這只機械腳可能是裝在B)“床腳”；C)“在床中間”和D)“在床下邊”似乎都不太符合正常的邏輯，所以都排除。

47、 4. The bed can wake you up in _ ways.A.threeB.fourC.fiveD.six答案:C解析 綜合歸納題。文章第二、三段介紹了這種特殊的床叫人起床的五個方法分別為：1鬧鐘響起；2輕音樂或輕柔的呼喚聲；3噪聲或難聽的呼喚聲；4用機械腳踢人；5床豎起，把人滑落至地下。 避錯 迅速地辨別出文中表示順序或時間的詞，有助于歸納出這種床叫人起床的五種方法。 例如：First，Next，a few minutes later，after the second recording，a few more minutes。 5. The main idea of the

48、 passage is _.A.how the bed worksB.who makes the bedC.why the bed is madeD.who can use the bed答案:A解析 主旨大意題。本題結(jié)合第39題進(jìn)行理解，文章主要介紹了這種床發(fā)揮作用的幾個步驟。由此可知，短文描述了一種床是如何發(fā)揮作用叫人起床的。 避錯 B)“誰造了這張床”和C)“為什么要造這張床”都只是文章的部分內(nèi)容，不能全面地概括文章的主要內(nèi)容；而D)“誰適合用這張床”，雖然在文章一開頭提到適用于早上不愿起床的人，但后文主要是圍繞這種床如何叫貪睡的人起床來展開的，故排除。 Directions:This

49、task is the same as Task 1, The 5 questions or unfinished statements are numbered 41 to 45. The world is not only hungry; it is also thirsty for water. This may seem strange to you because nearly 75% of the earths surface is covered with water. But about 97% of this huge amount is seawater or salt w

50、ater. Man can only drink and use the other 3%the freshwater that comes from rivers, lakes, underground, and other sources. And we cannot use all of that, because some of it is in the form of iceberg and glaciers (冰河). Even worse, some of it has been polluted. However, as things stand today, this sma

51、ll amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would

52、have a bad effect on agriculture and industry. We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only a small scale. The systems that have been worked out resemble

54、ople in the world all feel hungry and thirsty答案:C解析 語義理解題。文章第一句話采用了擬人的手法說明世界不但很餓而且還很渴，實際上隱含的意思是指人類不僅面臨著食品短缺的問題，同時水資源也非常缺乏。而本文側(cè)重介紹水資源匱乏的問題，所以C)符合題意。 避錯 A)中的our future needs和B)中的people all over the world與原文意思不符；而 D)只是表達(dá)了原文的字面意思，沒有體現(xiàn)出作者要表達(dá)的真正意圖。 2. The percentage of the earths surface that NOT covered

55、with water is_.A.75%B.25%C.97%D.3%答案:B解析 事實細(xì)節(jié)題。由題干中的線索詞earths surface和covered with water定位到文章第一段第三句。原文說75%的地球表面被水覆蓋，經(jīng)過簡單運算，那么地球表面沒有被水覆蓋的地區(qū)應(yīng)占25%。 避錯 A)75%是被水覆蓋的地區(qū)；C)97%和D)3%是指所有水資源中咸水和淡水各自所占的比例，所以均不符合題意。 3. The author says that we may face a severe worldwide water shortage in the future because_.A.the small amount of fresh water is constantly being replaced by rainfallB.some of the water has been pollutedC.our need for fresh water is
