參考答案

1.D解析：文章末尾講到“自然環(huán)境區(qū)已縮小成大片污染地帶中的小島”，說明鄉(xiāng)村地帶受工業(yè)發(fā)展的破壞，與D項(xiàng)符合。

2.C解析：推理判斷題。文章最后兩段談?wù)摰氖菋D女們的兩難境地：Havingchildren和keepingtheirjobs。最后一句“Inaword,Asiangovernmentsmusttakestepstoimprovethepresentsituationassoonaspossible.”可以判斷C項(xiàng)為最佳答案。

3.A本文的最后一句大意是：如果商家不確信廣告將帶給他們更大的利潤(rùn)，他們就不會(huì)花大量的錢去拍廣告了。由此可以推論出：商人確信廣告將他們帶來更大的利益。

4.D解析：文章第四段第一句話表明是大西洋電信公司向Maury求助的。

5.D解析：詞義辨別題。renovation的動(dòng)詞renovate是“修復(fù)”之意；reform意為“改革”；rearrange意為“重新安排”；retreat意為“撤退”；restore意為“恢復(fù)，重修”。

6.C解析：參見句子Shequeuedforabus,gotonandsatdownnexttoanoldlady.

7.D“splitup”一詞出現(xiàn)在文中第二段第三句，根據(jù)該短語所在句，我們可以得知，“splitup”與其后的“meetagain”意思相反。

8.D文中倒數(shù)第四句提到意大利人依靠電視來告訴他們發(fā)生什么，正好與D項(xiàng)對(duì)應(yīng)。

9.C解析：第四段。羊是最承受艱苦的動(dòng)物。它可以在非常貧瘠的土地上生存。選項(xiàng)c是正確的。

10.A解析：本題為是非判斷題。文章從一開始就闡明作者對(duì)青少年的叛逆心理的贊許。然而，青少年做得還不夠，他們易受流行浪潮的影響，易受家長(zhǎng)的影響。由此，我們可知B、C、D三個(gè)選項(xiàng)是符合文章內(nèi)容的。只有A項(xiàng)錯(cuò)誤。

11.D解析：第三段中提到，壓力會(huì)使人在情感上出現(xiàn)問題，如焦躁、不安、厭煩(feelingtired)等。

12.D

13.A從整個(gè)這段話開始的Goodevenin9到文章的敘述，不難推斷出答案應(yīng)為A。

14.B42．文章最后一段第二行，作者說他的父親曾經(jīng)參加過第一次世界大戰(zhàn)。但并未提及他是否參加了“二戰(zhàn)”。選項(xiàng)B是正確的。

15.C

16.B解析：細(xì)節(jié)題。文章第三段第二句中的“thesametypeofstorageproblem”指的是上文中提及的由wind，waveandtides提供的新能源的儲(chǔ)存問題。

17.A

18.B解析：第2段“AsfarasIcanremember，…”此句點(diǎn)明題意。

19.B事實(shí)細(xì)節(jié)題。

【應(yīng)試指導(dǎo)】從第四段的內(nèi)容可知，當(dāng)你面朝窗戶時(shí)，書頁又處在了影子中。

20.D

21.A見原文第四段。Keiko一兩歲時(shí)被抓，之后不停地北轉(zhuǎn)過多處地方飼養(yǎng)。但所有地方都在冰島的南邊，水溫比冰島高，而且已經(jīng)是將近30年了。因此當(dāng)人們決定把它放歸大自然，回到它自己的家鄉(xiāng)冰島時(shí)，擔(dān)心它已不能適應(yīng)那里的低水溫了。但相反，它非常適應(yīng)。

22.B

23.D解析：文中第二段第二行中“Edisonhadsolvedcertainproblems,makingitpossibleforotherinventorsmoveaheadwiththeirowndevices.”給出了答案。

24.D通讀文章第二段，可知作者將老師比做醫(yī)生，老師的作用象給病人看病一樣，因而正確答案應(yīng)是D項(xiàng)。

25.D解析：本題為細(xì)節(jié)判斷題。研究人員只是用不同于衛(wèi)星的調(diào)查方法研究亞馬孫河流域森林遭破壞的程度，主要是人為的破壞而沒有調(diào)查洪水對(duì)森林的破壞。

26.A解析：本文是通過具體的實(shí)驗(yàn)來得出一些關(guān)于人們行為的科學(xué)結(jié)論，因此選項(xiàng)A正確。

27.D

28.A42．答案為A。根據(jù)第四段第一句主題句Disabledpeoplefacemanyphysicalbarriers作出該項(xiàng)選擇。

29.C解析：參見第五段。Hale說今天的人們用得更多的是電子郵件。

30.D

31.C句意為：從那以后，當(dāng)我開始對(duì)某人感到憤怒時(shí)，我就會(huì)想起他的話，然后平靜下來。would表示“意愿”。而should表示“應(yīng)該做……”；could表示“能夠做……”；might表示“或許，可能……”，均不合題意。

32.B

33.B解析：見上一條。

34.D

35.B解析：這一段和上一段說明關(guān)閉失聰學(xué)校的兩個(gè)原因。上一段說軍隊(duì)駐扎是學(xué)校關(guān)閉的一個(gè)原因，這段說教師加入戰(zhàn)爭(zhēng)是學(xué)校關(guān)閉的另一個(gè)原因。后面給了兩個(gè)教師參與戰(zhàn)爭(zhēng)的例子。因此，此處不會(huì)是學(xué)校轉(zhuǎn)移或搬家等。transfer意為“轉(zhuǎn)移”；move意為“搬家”。

36.C

37.C解析：由此句的主語(蜜蜂的知識(shí)學(xué)習(xí))可知，此處需要填入代詞，由于代替的是learning，因此，只有that能代替不可數(shù)名詞的learning，故C是正確答案。

38.B解析：根據(jù)Britishcolonies可推測(cè)應(yīng)表示各種“人口”。

39.C30．答案為C

in表示“在某方面”。

40.A解析：2002年2月以來，已有750萬的禁帶物品被扣押。

41.D操持語言的人數(shù)可以估計(jì)，但人們掌握語言的程度就很難估計(jì)了，所以用impossible。

42.A根據(jù)上下文，這里指的是用不同的材料做家具。制作家具用make。A項(xiàng)是正確的。

43.C解析：小孩想去動(dòng)物園，便不停地發(fā)出尖叫聲，故選voice。ashrillvoice與scream的意思接近。volume(音量)；noise(噪音)；pitch(音調(diào))均不合要求。

44.A解析：作者首先指出人生來大腦不一樣，接著指出后天的學(xué)習(xí)不可少。這里含轉(zhuǎn)折關(guān)系。

45.D解析：如果某個(gè)人或某個(gè)組織想要告訴公眾他或他們對(duì)這個(gè)事件或候選人是如何考慮的。

46.C解析：由下文觀點(diǎn)排除A、B兩項(xiàng)，由最后一段知作者是欣賞警察行事的態(tài)度與精神，而不是羨慕。

47.C解析：本題為固定搭配題。Itisagoodideatodo…意為“做……是個(gè)好主意”。本句大意為：吃飯時(shí)，給孩子少一點(diǎn)是個(gè)好主意，讓他自己再來要第二次。

48.D解析：此處是“with+n.+adv.”構(gòu)成的復(fù)合結(jié)構(gòu)作伴隨狀語。

49.B詞義辨析題。

【應(yīng)試指導(dǎo)】本句講的是鱷魚吃人，人們要靠近鱷魚，必然與水有關(guān)系，所以此處應(yīng)為“洗衣服的婦女”，選B。

50.C解析：Offersbsth為某人提供某事?？蘸笫怯新犃φ系K的人，由and連接，可以斷定and前也應(yīng)該是某種人。根據(jù)上下文，應(yīng)是失聰?shù)娜恕＿x項(xiàng)C是正確的。

51.D

52.CA、B、D三項(xiàng)劃線字母w發(fā)[w]，而C項(xiàng)中劃線字母w不發(fā)音，因此選C項(xiàng)。

53.A解析：畫線部分讀[z]，其他選項(xiàng)的畫線部分讀[θ]。

54.B

55.D

56.B解析：該題測(cè)試元音字母。的讀音。A、C、D選項(xiàng)中o發(fā)[cu]音；B選項(xiàng)中o發(fā)[c]音。

57.D解析：A，B，C項(xiàng)劃線部分發(fā)[c]，而D項(xiàng)劃線部分發(fā)[A]，所以選D項(xiàng)。

58.B

59.D解析：本題屬元音字母辨別的考查題，可利用排除法。A、B、C三項(xiàng)當(dāng)中的發(fā)音均為[/\]，只有D項(xiàng)中發(fā)音為[ju:]。故選D。

60.B

61.Bcompare…with…把……與……比較；compare…to…把……比作……。句意為：他把音樂比作生命。

62.C解析：根據(jù)語境，此處缺少表示轉(zhuǎn)折關(guān)系的連詞，when意為“然而，可是”，引導(dǎo)狀語從句。

63.B解析：breakup意為“打碎，分裂”；breakoff意為“斷絕，結(jié)束”；breakout意為“爆發(fā)”；breakdown意為“崩潰，瓦解”。根據(jù)題意，應(yīng)選B。

64.C解析：本題測(cè)試動(dòng)詞辨義。accumulate意為“積累”；collect意為“收集”'assemble意為“集合”'resemble意為“像”。本句大意為：導(dǎo)游讓游客們?cè)陲埖觊T口集合。

65.D解析：本句是對(duì)上句的重復(fù)，盡管用so開頭，語序也不倒裝。

66.Bbreakout意為“(戰(zhàn)爭(zhēng)、疾病)的突然發(fā)生”，符合句意。breakoff意為“中斷，絕交”；breakdown意為“拋錨，出故障”；breakup“打碎，分解”。

67.D

68.D

69.B解析：exhausting一般修飾物。exhausted修飾人，意為“很疲憊”。

70.C解析：在“Itis+表示提議、要求、命令等含義的動(dòng)詞過去分詞+that分句”這一結(jié)構(gòu)中，從句謂語動(dòng)詞用“動(dòng)詞原形”或“should+動(dòng)詞原形”表示虛擬語氣。

71.B解析：題中“hewouldvisitme…Christmas”是promise的同位語。

72.D

73.C解析：句中’d是would的縮寫。

74.B解析：putaway收起，放好。

75.Dhazard意為danger。

76.Cfailtodosth．“做某事失利”或“沒有做某事”，此處無需用完成體。

77.D解析：as…as…表示“與……一樣”，as與as之間用形容詞或副詞的原級(jí)。

78.B解析：分詞短語作狀語時(shí)，其邏輯主語與句子主語相同，本句主語是I。選項(xiàng)B=WhenIreturnedtotheroom，Ifoundthebookmissing.

79.B本題考名詞的形似詞辨析。content意為“內(nèi)容”；contest意為“競(jìng)賽”；context意為“上下文”；consent意為“同意”。結(jié)合句意，故B項(xiàng)正確。本句大意為：在全國(guó)數(shù)學(xué)競(jìng)賽中他獲得了第一名。

80.B解析：不定式作目的狀語，句子的主語必須是不定式的邏輯主語，故答案應(yīng)選B。

81.61．寫作格式與第三套一樣，不同的是此處段首句以英文給出。本文要點(diǎn)：論述健康對(duì)我們的影響，有了好身體我們可以做什么。如何保持健康：1)要進(jìn)行鍛煉，2)要養(yǎng)成好習(xí)慣，3)要自己注意身體變化。HealthHealthisthefoundationofone'sfuturesuccess.Ifyoubecomesick,itisimpossibleforyoutogoonwithyourstudyoryourwork.Onthecontrary,ifyouarestrong,youcanovercomethedifficultiesthatlieaheadofyou.Howcanyouhavegoodhealth?Firstly,youshoulddoexerciseeverydaytostrengthenyoubodies.Secondly,youshouldform.somegoodhabits,suchasearlyrising.Ifyougetupearly,youcanbreathefreshair.Thirdly,youshouldpayattentiontoyourhealth.Ifyouaregettingsick,you'dbetter,gotoseeadoctor.Inaword,nothingismorevaluablethanhealth.Ingood
