【答案】第1题:B

第2题:D

第3题:D

第4题:A

第5题:C

【解析】1.【试题解析】细节事实题。由题干关键词olestra可以定位到文章第六段中“Itjustslidesthroughtheintestineswithoutbeingbrokendown.”中文翻译为：它（即奥利斯特拉）滑过肠道而不被分解，以及“Itprovidesconsumerswiththetasteofregularfatwithoutanybadeffectsonthebody.”中文翻译为：它（即奥利斯特拉）为消费者提供一般脂肪的味道而不对身体产生有害作用。可以得知B项“在让食品可口的同时，不让其含有脂肪”符合题意。

2.【试题解析】细节事实题。由题干可以定位到原文第三段“Insteadoffindingthedesiredfat,theresearcherscreatedafatthancan’tbedigestedatall.”中文翻译为：研究者没有发现期望的脂肪，相反他们创造了一种根本不被消化的脂肪。因此可知D选项“很意外的”为正确答案。

3.【试题解析】细节事实题。由题干关键词olestra可以定位到文章第六段“Itjustslidesthroughtheintestineswithoutbeingbrokendown.”中文翻译为：它（即奥利斯特拉）滑过肠道而不被分解。可以得知D选项“它穿过肠道而不被吸收”符合题意。

4.【试题解析】推理判断题。由题干关键词olestra可以定位到文章第六段中“Itcanalsopreventtheabsorptionofcarotenoids,compoundsthatmayreducetheriskofcancer,heartdisease,etc.”中文翻译为：它（即奥利斯特拉）也可能阻止类胡萝卜素的吸收，而该化合物可能降低忠癌症、心脏病等的风险。故选A“它可能增加患癌症的风险”。

5.【试题解析】推理判断题。根据题干可以定位到文章尾段“Evenso,somenutritionistsarestillconcernedthatpeoplemighteatunlimitedamountsoffoodmadewiththefatsubstitutewithoutworryingabouthowmanycaloriestheyareconsuming.”中文翻译为：即使如此，一些营养学家仍然担心人们可能在不用担心自己正消耗多少热量的情况下，无限制地吃用脂肪替代物制成的食品。判断出答案为C项“人们可能被引诱去吃多出需要的食品”。

5.单选题

Thechocolatecompanymaintainedstablesales______andincreasedprofitsby4.7%inthefiscalperiodendinginFebruary.

问题1选项

A.volumes

B.rows

C.dimensions

D.outputs

【答案】A

【解析】考查名词词义辨析。A选项volumes“体积，容量”；B选项rows“一排，一行；一排座位；排屋，排房”；C选项dimensions“规模，大小”；D选项outputs“输出”。句意：在2月份结账期结束巧克力公司保持稳定的销售……，并增加了4.7%的利润。salesvolumes为固定搭配，译为销售量，因此A选项正确。

【答案】第1题:C

第2题:D

第3题:C

第4题:D

第5题:A

【解析】6.【试题答案】C

【试题解析】词义推测题。由题干可以定位到原文第一段第一句Inthecollege-admissionswars,weparentsarethetruegladiators.（在大学入学的战争中，我们父母是真正的角斗士）。C选项“战士”与“角斗士”的意思相近，因此C选项正确。A选项“巨人”，不符合文章内容。B选项“指挥官”，不符合文章内容。选项D“贪吃的人”不符合词义，可排除。因此C选项正确。

7.【试题答案】D

【试题解析】观点态度题。由题干可以定位到原文第一段倒数第三句Wesayourmotivesareselflessandsensible.（我们说我们的动机是无私和理智的。）D选项“不同意的”正确，根据下文内容可推测，父母宣称是无私的和明智的是虚假的，因此作者不同意这个观点。A选项“反感的”，可排除。B选项“冷漠的”，作者态度并不是冷漠的，可排除。C选项“矛盾”，不符合文章内容，可排除。因此D选项正确。

8.【试题答案】C

【试题解析】主旨大意题。由题干可以定位到原文第四段（我们有一种全面的威望恐慌；我们担心没有足够的奖杯。恐惧的父母催促他们的孩子申请比以往更多的学校。阿默斯特学院招生主任汤姆•帕克（TomParker）说，过去，父母焦虑的中心集中在沿海地区：波士顿、纽约、华盛顿和洛杉矶）。选项C“父母不应该给孩子太多的压力”，文中所说父母催促孩子申请比以往更多的学校，因此可推测，父母给孩子的压力过大，C选项正确。选项A“美国年轻人的选择很少，只能去精英学校”，不符合文章内容，可排除。选项B“在美国，精英学校的竞争更加激烈”，不符合文章内容，可排除，选项D“如果不上精英学校，孩子们的未来将是暗淡的”，没有必然的关系。因此C选项正确。

9.【试题答案】D

【试题解析】推理判断题。由题干可以定位到原文第六段中最后一句Theyearnedjustasmuchasgraduatesfromhigher-statusschools.（他们挣的钱和那些地位较高的学校的毕业生一样多）。D选项“在教授反馈方面，他们的表现并不优于其他学校”，由挣钱这一点反映，他们的表现并不优于其他学校，D选项正确。A选项“重点学校为学生提供更好的教学方法。”文章第五段提到“名校并不比非名校系统地采用更好的教学方法”，因此A选项可排除。B选项“重点学校的考试比其他学校多。”第五段最后一句提到“教授的反馈和论文考试的数量——重点学校的表现略差”，B选项可排除。C选项“他们的新教学方法确保了毕业生的高薪”，文中第六段提到“他们挣的钱和那些地位较高的学校的毕业生一样多”，因此C选项可排除。因此D选项正确。

10.【试题答案】A

【试题解析】作者意图题。由题干可以定位到原文倒数第二段TheveryambitionweimposeonourchildrenmaygetsomeintoHarvardbutmayalsosetthemupfordisappointment.（我们强加给孩子们的雄心壮志可能会让一些孩子进入哈佛，但也可能会让他们失望）。由此可知选项A“太多的压力可能会导致不满意的结果”，符合文章内容，A选项正确。B选项“他们自己的抱负不应该由他们的孩子来实现”，文章没有提到父母的抱负让孩子实现，B选项可排除。C选项“他们的孩子可能经常跳槽”，文章没有提到此内容，可排除。D选项“他们的孩子可能和他们没有共同的兴趣爱好”，文章没有提到此内容，可排除。因此A选项正确。

7.单选题

问题1选项

A.peoplehave

B.sincepeoplehave

C.havepeople

D.peoplewhohave

8.单选题

Intheendthelittleboywenttoschoolwithoutsomucha________ofprotest.

问题1选项

A.whimper

B.whim

C.whirl

D.whistle

【答案】B

9.问答题

问题1选项

D.insignificantly

【答案】A

【解析】【试题解析】考查副词辨析。A选项fundamentally“根本地”；B选项comparatively“相对地”；C选项certainly“无疑地”；D选项insignificantly“无关紧要地”。句意：计算机革命很可能像工业革命一样______改变社会。根据语境，这里指的是计算机革命和工业革命一样对社会的影响重大，A选项fundamentally“根本地”符合题意。题干中提到计算机革命很可能会改变社会，C选项certainly“无疑地”错误。因此A选项正确。

【答案】第1题:D

第2题:C

第3题:A

第4题:B

第5题:C

【解析】1.细节事实题。由文章第一段中的Forcenturies,explorershaveriskedtheirlivesventuringintotheunknownforreasonsthatweretovaryingdegreeseconomicandnationalistic.（几个世纪以来，探险家们冒着生命危险去探索那些不为人知的地方，或多或少是由于经济的或国家利益的原因）可知D选项“追求商业和国家利益”符合题意。

2.推理判断题。由文章第三段中的Andwithdoubtfulprospectsforashorttermfinancialreturn,withthecoldwararapidlyfadingmemoryandamidagrowingemphasisoninternationalcooperationinlargespaceventures,itisclearthatimperativesotherthanprofitsornationalismwillhavetocompelhumanbeingstoleavetheirtracksontheplanet'sreddishsurface.（由于短期财政回报的前景令人怀疑，冷战记忆的迅速消失，以及人们对大型太空探险国际合作的日益重视，很显然，现实需求已压倒经济利益和民族主要诉求，促使人类离开通向这座表面呈红色的星球的轨道）可排除B、D选项，A选项“国际合作”是进行太空探险的方式，故排除，因此选C。

3.推理判断题。由文章最后一段中的Theissueofwhetherlifeeverexistedontheplanet,andwhetheritpersiststothisday,hasbeenhighlightedbymountingevidencethattheRedPlanetoncehadabundantstable,liquidwaterandbythecontinuingcontroversyoversuggestionsthatbacterialfossilsrodetoEarthonameteoritefromMars.（越来越多的证据显示，这颗红色星球曾经有过大量稳定的液态水，关于掉落到地球的火星陨石上有细菌化石的说法一直存在争议，这些都突出了一个问题——火星上是否存在生命，以及这些生命到现在是否还一直生存在火星上）可知A选项“看那里是否存在生命”符合题意。

4.推理判断题。由文章最后一段中的IfitcouldbeestablishedthatlifearoseindependentlyonMarsandEarth,thefindingwouldprovidethefirstconcretecluesinoneofthedeepestmysteriesinallofscience（如果可以确定生命是在火星和地球上独立产生的，这一发现将为所有科学中最深奥的奥秘之一提供第一条具体线索）可推测风险越大，回报越高，因此选B。

5.细节事实题。由文章最后一段中的AmoreconclusiveansweraboutlifeonMars,pastorpresent,wouldgiveresearchersinvaluabledataabouttherangeofconditionsunderwhichaplanetcangeneratethecomplexchemistrythatleadstolife.（一个关于火星上生命的更确切的答案，无论是过去的还是现在的，都会给研究人员提供宝贵的数据，了解到行星在何种条件下都可以产生导致生命的复杂化学物质）可知C选项“揭示生命起源的类型”符合题意。

16.单选题

Don’t（meddle）inmyaffairs,andinfactIcanhandlethemproperlybymyself.

问题1选项

A.interfere

B.interest

C.involve

D.attend

【答案】A

【解析】考查动词辨析。meddle表示“干涉，管闲事”；A项interfere“干涉，妨碍”，B项interest“感兴趣”，C项involve“包含，牵涉”，D项attend“参加”。句意：不要干涉我的事情，事实上我自己能处理得很好。根据句意可知，该题选择A项正确。

【答案】第1题:D

第2题:C

第3题:B

第4题:D

【解析】1.判断推理题。根据第二段最后一句“thebetterproteinqualityintortillasmadefromopaque-2maizewillbeofonlylimitedbenefittoafamilyonthemarginofsubsistenceifthenewmaizeisnotculturallyacceptableorismorevulnerabletoinsects.如果这种新玉米在文化上不能被接受，或者更容易受到昆虫的侵害，那么用不透明2型玉米制成的玉米饼所含的蛋白质尽管质量较好，但对处于生存边缘的家庭所带来的利益将是有限的。”作者的重点在于强调它比其他玉米品种更容易受到昆虫的侵害，所以选项D符合题意。

2.细节事实题。根据第二段的二三句“Asuccessfulnewtechnology,therefore,mustfittheentiresocio-culturalsysteminwhichitistofindaplace.Securityofcropyield,practicalityofstorage,palatability,andcostsaremuchmoresignificantthanhadpreviouslybeenrealizedbytheadvocatesofnewtechnologies.因此，一项成功的新技术必须适应它所处的整个社会文化系统。作物产量的安全性、储藏的实用性、风味和成本都比以前新技术的倡导者所认识到的要重要得多。”选项A，B，D均有所提及，所以本题选C。

3.细节事实题。根据关键词“Antarctickrill”定位到第一段最后一句“Recentinnovationssuchasopaque-2maize,Antarctickrill,andthewheat-ryetriticaleseemmorepromising,butitistooearlytopredicttheirultimatefate.最近的创新，如不透明玉米、南极磷虾和黑小麦似乎更有希望，但现在预测它们的最终命运还为时过早。”所以选项B符合原文。

4.判断推理题。第一段最后一句指出“itistooearlytopredicttheirultimatefate.现在预测它们的最终命运还为时过早”。选项A在文中没有提及；选项B太过于绝对；选项C表述过于片面，只有选项D能够全面的概括第一段的内容，所以正确。
