参考答案

1.medicalmeasuresmedicalmeasures解析：题干中要求填入名词性成分作介词for的宾语。由该句可知，根据alivingwill，当某人过度虚弱或丧失行为能力时，可依据该人要求采取医疗措施。因此medicalmeasures符合题干要求，为正确答案。

2.yourprogressyourprogress解析：根据题干中的信息词measuringyourwork定位到第二个小标题，再由encouragesyourdevelopment定位到该部分提到的12个问题，其中倒数第二个问题中提到了talktomeaboutmyprogress，由此可得答案，即在评估自己的工作时，有必要考虑工作中是否有人鼓励你发展，是否有人和你谈到你的进步。

3.proof-of-citizenshiprequirementsproof-of-citizenshiprequirements解析：根据题干关键词native-bornAmericans，healthinsurance，original定位到第十段第二句Thereareproof-of-citizenshiprequirementsthatevennative-bornAmericansmayhavedifficultymeetingbecausetheydonothavetheiroriginalbirthcertificatesorotherdocumentation.由此可知，即使是土生土长的美国人想得到健康保险也不得不根据公民身份确认准则的相关法规定提供原始出生证明和相关的文件，故答案为proof-of-citizenshiprequirements。

4.KidneyKidney解析：细节理解题。根据第三段，在可以预防的癌症中，未提及kidneycancer(肾癌)，而larynxcancer(喉癌)，rectumcancer(直肠癌)，breastcancer(乳腺癌)都被提到了。

5.furtherwarming。furtherwarming。解析：根据题干中的信息词permafrost和speedup定位到第七个小标题下的第三段，可知全球变暖将导致一些会加速进一步变暖的变化，例如说随着永久冻结带的融化所释放出的大量温室气体甲烷，由此可得答案。

6.shortandnastyrelationships

7.A解析：根据标题WhereDoestheHydrogenComeFrom?下末段首句Wherewilltheelectricityfortheelectrolysisofwatercomefrom?可以发现，Currently，about68percentoftheelectricityproducedintheUnitedStatescomesfromcoalornaturalgas．而about68percent表明，大部分电都来源于煤和天然气。

8.bothbuyersandsellersbothbuyersandsellers解析：参见文章倒数第四段。

9.suitable

10.C解析：第四句中提到了一项研究在2年时间后的成果：实施了压力管理计划的公司在员工赔偿开支方面节省了15万美元，而项目的支出只有6000美元。既然是公司节省了开支，显然是为了说明对于雇主的好处，故答案为[C]。例证处设题。注意分析观点与其证据之间的关系。

11.achieverapidprogressagainstthemtooachieverapidprogressagainstthemtoo解析：细节题。根据题干定位到文章末段倒数第二句Thisgivesusgoodreasontohopethatifweacttosolvetheenvironmentalproblemsthatstillremain，wewillachieverapidprogressagainstthemtoo，即：这给了我们一个很好的理由去希望，如果我们行动起来去解决仍然存在的环境问题，我们也会在对付这些环境问题上取得显著的进步，故得答案。

12.B解析：根据该句可知，这种情况下，寿保将立刻提供关于葬礼的各项开支。可知B)与原文相符。

13.wirelessnetworkingwirelessnetworking解析：本题定位信息是security，从而锁定BluetoothSecurity部分。该部分第一段前三句提到，Inanywirelessnetworkingsetup，securityisaconcern…Bluetoothtechnologyisnodifferent—it'swireless。由此可知，蓝牙技术的安全问题源于它的无线网络连接的本质。故本题应填入wirelessnetworking。

14.B解析：通读文章可以看到，文章的第一段写到了加拿大北极冰和永久冻结带的融化，拉丁美洲和南亚的暴雨和洪水，欧洲冰川的消失，森林大火等等。所以各个地区的气候变化导致的结果是不同的。

15.benefitsbenefits解析：由题干关键词features可将答案定位至第二个小标题下第四段第二句。Itmeanstosellthebenefits，notthefeatures。benefits就是答案。

16.AmericaAmerica解析：根据文章第八段所言，许多罪犯不是逃到美国以避免受罚的，而是由英国人把他们装到船上运往美国的，因为对英国人而言，他们不是“好公民”。

17.C

18.C解析：本题定位信息是spread-spectrum，从而锁定BluetoothOperation部分。该部分只是在第四段最后一句提到了与手机相关的信息，ThissametechniqueminimizestheriskthatportablephonesorbabymonitorswilldisruptBluetoothdevices，但是并未提到题干中所说的“随着扩展频谱技术的发展，我们可以用蓝牙技术来代替手机的应用”。题干表述在文中找不到依据，因此答案为NG。

19.B解析：本题定位信息是thenextcomputer，涉及到了移动手机是否能成为下一代计算机的问题，从而锁定Canthecellphoneturnintothenextcomputer?部分。该部分第一段的前两句提到，…mobilehandsetturningintothenextcomputer?Inonesense，italreadyhas。题干中的completely相对于文中的inonesense(就某种意义来说)扩大了表达范围，因此答案为N。

20.A解析：根据题干信息词clotscanform定位到第三个小标题下的第三句Clotscanform.whenbloodsupplyslowsorstops,suchasinaperiodofprolongedimmobility，即：当血液供应放慢或者停止供应的时候，例如长时间的不移动，就会形成血栓，故答案为A。

21.C解析：W:Igotoutofascienceclasslateagain.Inevermakeitheretoworkontime.IhopeIwon'tgetintrouble.

M:Thebossisinagoodmood.Maybeshe'llgiveyouabreakthistime.

Q:Whatdoesthemansayabouttheboss?

22.B解析：选项B、C表明对话可能与研究报告的选题有关，选项A、D表明对话可能与选择课程有关。男士正为政治学研究报告的选题犯难，女士说Mary正在作政治学的毕业设计，可见是建议男士去找Mary帮忙进行选题。narrowdown意思是“把(范围等)缩小，变窄”，narrowthetopicdown指“从预选的题目中挑出合适的一个”。

23.D

24.plains

25.hasten

26.C解析：信息明示题。由文章中的Theprivateorganizationknownas"ChildHopeU.S.A.”...可知，该组织是私人机构，故选C。

27.D解析：Whydidthewomandecidetoridethecitybus?

女士决定乘公共汽车的原因是I'vejustbeenthinkingalotabouttheenvironmentlately．SoIdecidedtheairwillbealotcleaner…，即她认为公共交通系统能减少空气污染，故选D。theairwillbealotcleaner≈reducepollution。

28.fairly

29.C解析：选项均以-ing形式开头，且宾语各不相同表明，本题可能考查涉及到短文主题的正在进行的动作。短文开头即提到，Yourassignmentsthistermwillbetowritetwomajorresearchpapers，故答案为[C]。

30.B

31.enjoy

32.limits

33.passionatepassionate解析：passionate意为“充满激情的”。根据空前面系动词be及后面的介词about，可以判断此处所填的词为形容词。

34.D

35.D

37.ThereisnoprovisioninthelawstodifferentiatebetweenanaccidentalordeliberatecontractThereisnoprovisioninthelawstodifferentiatebetweenanaccidentalordeliberatecontract，

38.opponents

39.warmthwarmth解析：此处应该填入一个名词，前面有了限定成分its。

40.D解析：间接建议题。男士问：“火车在希尔顿街停不停?”女士没有直接回答他，而是告诉他门口有线路图。所以答案选D。干扰选项：A男士应该问门口的那个人；B男十应该问售票员；C女士将告诉男士什么时候下车。

41.D解析：主旨题。文章第三段首句指出，城市的很多变化使野生动物又回来了，接下来的内容又谈论了一些具体的变化。由此可知，本段主要论述了野生动物回到城市里的原因，所以D正确。

42.A解析：根据题干中theevolution…toflatleaves，可以定位到第六段第二句。这句提到二氧化碳的下降可能导致了阔叶树木的进化，因为阔叶可以吸收并保持更多的植物所需的气体(flatleavesontreestoattractandretainmoreofthegas)。森林数量的增长并未导致阔叶树木的进化，故可排除B；温度的下降以及气候变成了像现代的样子也不是导致阔叶树木进化的原因，故可排除C、D。

43.B解析：文中提到"...theyjustwantedtobewarm"。

44.installmentsinstallments解析：参见文章第二段第三、四句：你也可以选择把支付的款项分几个月付清，每月只付总款的一部分(即installments)，若以这种方式还款，信用卡公司或者发行信用卡的银行要收取一定的服务费。

45.KK解析：根据上下文，此处应填动词。这里意为：选择父母认同的对象结婚。所以填approve一词。approvevt.vi.认可；通过；(常与of连用)赞成，赞同。如：Idon'tapproveofwastingtime．我不赞成浪费时间。Themayoressapprovedthenewbuildingplans．女市长批准了新建筑计划。

46.A解析：词义推断题。从上下文可以推断出代词it指示Americanmovieindustry。且it文后有“todevelopitspotentialasanartform”，因此，正确答案为A项。

47.A解析：通过仔细阅读比较对具有四种不同人格的人的叙述和第二段中"Easilydistracted，theyoftenlacktheconcentrationtocompleteajoborotherpeoplemaynottrustthem"，我们可以发现A是正确答案。

48.B解析：根据题干improvecommunicationswithkids定位于末段末句。...themajorityofparentswhotexttheirchildrenfeltthatitimprovedcommunicationswiththeirkidsandmadethemeasiertoreach.细节题。文章的末段后半部分着重描述对于家长来说如何改进和孩子的关系。Onewaytowinbrowniepointswithyourgrandkidsistoflexyourthumbsonyourcellphonekeypadandsendthemtextmessages．“要想从孙子那里赢得他的核仁巧克力饼，那你就应该把你的手指放在手机键盘上给他们发送信息”，此句传达的含义就是家长要想改进关系就应当尝试应用一些新的交流方式了解孩子们，从而拉近距离。B)的表述最完整、切题。A)具有迷惑性。为了与孩，予拉近距离，家长确实需要学习现代技术，但是也并非需要适应全部的新科技。此表述过于绝对。

49.B

50.D解析：根据第四段最后一句话，可知D项正确。A、C两项文中并未提到。第三段最后一句话这里的destinies正是指的一种自我把握的经济独立而非对商贸的控制。以前发展中国家就种这种控制，现在当然谈不上失去控制。

51.OO解析：联系上下文，可知profit为正确的答案。

52.domesticjobsandincomesdomesticjobsandincomes解析：本题要填入support的宾语。由定位句可知，当各国都无繁荣可言时，国际贸易就不再受到欢迎，政府也就因此转向支持国内的工作和收入，可推知本题答案为domesticjobsandincomes。

53.HH解析：空中应填名词。此处是在描述讲HIV感染初期的症状表现。exposure有“感染”之意，与该语境相符，即病人初次感染HIV后会在几周或几个月内出现发烧症状或严重的嗓子疼，因此H.为答案。选项中的其他名词A.destruction“破坏，毁灭”和J.segregation“隔离”均与afeveroraseveresorethroat没有关联。

54.complicatedtimeconsumingandsometimesevenoverwhelmingcomplicated,timeconsumingandsometimesevenoverwhelming解析：本题根据第三段最后一句而设。

55.Becausenooneknowswhattoexpectfromtheabundance.Becausenooneknowswhattoexpectfromtheabundance.解析：推理判断题，转折处命题。根据文中第一段第四句Yet，insteadofjoy,thereiswidespreaduneasinessandconfusion．“然而，人们并不高兴，相反，社会上充满了不安和迷惑”以及最后一句Nooneknowswhattoexpect．“没人知道下
