【答案】第1题:A

第2题:A

第3题:C

第4题:B

第5题:B

【解析】1.细节判断题。根据题干关键词Mach定位到文章第一段中，由Machisdefinedas“theratioofthevelocityofarocketorajettothevelocityofsoundinthemediumbeingconsidered.”（马赫被定义为“在被考虑的媒介中，火箭或飞机的速度与声速的比率”）可知选A。

2.细节事实题。由文章第三段中的Soundisproducedbyvibrationsofanobjectandistransmittedbyalternateincreaseanddecreaseinpressurethatradiateoutwardthroughamaterialmediaofmolecules（声音是由物体的振动产生的，并通过分子的物质介质向外辐射的压力的交替增加和减少而传播）可知A选项“物体通过空气的振动”符合题意。

3.细节事实题。根据题干关键词decibel定位到文章倒数第二段中，由Intensity,orloudness,isthestrengthofthepressureoftheseradiatingwavesandismeasuredindecibels.（强度，或响度，是这些辐射波的压力强度，以分贝为单位）可知C选项“测量声音强度的单位”符合题意。

4.推理判读题。文章最后一段的“Itvariesinothertemperaturesandindifferentmedia.（它在其他温度和不同的介质中变化）”中的it指的是前句中的“thespendofsound（声音的速度）”，然后介绍了在不同介质中传播的速度不同，因此B选项“声音以不同的速度在不同的温度和不同的介质中传播”符合题意。

5.主旨大意题。A选项仅适合文章第一段的主题；C选项仅适合第四段和第五段的主题；D选项仅适合第六段的主题。文章首段与尾段都提到了声音的速度，中间也有提到，因此B选项“声音的速度”符合题意。

2.单选题

B.shield

C.shade

D.rescue

【答案】B

【解析】recoverfrom恢复;shield与from庇护,使免遭……;shade不与from搭配,rescuefrom从...中营救。句意：应该用塑料布把树裹起来,以防止风和霜冻。选项B符合句意。

3.单选题

）thegame,unlessyoupracticeeveryday.

问题1选项

A.tolearntoplay

B.bylearningtoplay

C.inlearningtoplay

D.havinglearnedtoplay

【答案】C

【解析】句意:除非你天天练习，不然学玩游戏是没有意义的。

【答案】参考译文：

不论男女，青少年们都喜欢不顾家长的指导，自己对一切作决定，特别是当他们面对如性、心理压力等等一些使他们觉得羞愧和尴尬的问题时更是如此。因此，由于他们理解力和判断力的不足，他们常常会无意识地陷入困境中。有的对香烟上瘾，只要几包就会对他们的肺造成损害，使他们很容易就气喘吁吁；有的没法戒酒，喝酒带来的不良后果包括造成年轻的怀孕女性流产或生下不正常的婴儿；最糟糕的是滥用毒品，因为一旦他们的身体对毒品习惯了，要想戒毒就相当困难了。同时，那些共用从非法药剂师处购买的注射器的青少年还承担着感染令人绝望的艾滋病的极大风险。一旦感染上，不管是打针还是吃药都没法保证他们的生存了。

然而，请不要轻易就对我们的孩子失望或抱有偏见，毕竟，不成熟是年轻的必然附属品。只要我们加强和他们的沟通，而不是仅仅禁止这样，不准那样，我们一定能帮助他们避开不健康的东西。

【答案】第1题:C

第2题:D

第3题:C

第4题:B

第5题:A

【解析】第1题:本题考查了对细节的理解。题目问的是并购支持者为什么认为铁路行业内不会形成垄断。答案要在第二段的前半段中找，因为后半段说的是货主们的观点。支持者们认为：“Anythreatofmonopoly,theyargue,isremovedbyfiercecompetitionfromtrucks.”，意思是：因为要和卡车（指公路运输）竞争，所以不存在垄断的可能。所以C选项最符合文章的意思。A项不对，文章说支持者认为合并能降低成本，与竞争没有关系。B项没有根据。D项把主语和宾语弄反了，而且也不是支持者的观点，所以也是错误的。

第2题:这题和上一题是一样的。上题问的是支持者的观点，本题问的是货主的态度，要求考生根据文中所提供的线索做判断。通过文章中几处对托运商的描述，如：“Butmanyshipperscomplainthat...”（第二段），“Manycaptiveshippersalsoworry...”（第五段），“Manycaptiveshippersfearthat...”（第五段），我们可以判断出货主的态度是忧虑的，对未来的状况忧心忡忡。所以D选项是正确的。C项并不对。C项的含义是“愤怒的”。这篇文章是论说性的文章，反映的是各方对铁路行业内合并的趋势和前景的看法。文中的许多描述用的是将来时，因为是对未来的推测。文中并没有线索说明货主们有强烈的敌对情绪，C项言过其实了。

第3题:本题考查了段落细节的理解。需要考生具有推理能力和引申能力。A项正好与原文意思相反。从第三段第二句中，我们得知铁路公司合并后，铁路公司向货主们收取的费用是以前的20％至30％，所以，应该是“Shipperswillbechargedmorewithoutarivalrailroad.”。B项缺乏依据，所以也是不对的。C项是正确的，因为文章里说到：货主们若认为铁路公司收费不合理，可以向联邦政府的机构申请降低收费。但是，因为申诉的过程耗时费钱，所以极少人提出申诉。由此，我们可以推断出受到剥削的货主们不大可能提出申诉。D项说的是政府能保证铁路行业内的公平竞争。这种说法缺乏依据。事实上，由于货主们申诉的困难大，更多时候政府部门不会管。

第4题:该题考查的是考生对于具体词义的掌握及推测能力。“arbiter”的意思是“仲裁者”。考生可以通过上下文猜测到这个含义。这个词出现在第四段的最后一句，其实它要表述的内容已在前一句体现了：“It'satheorytowhichmanyeconomistssubscribe,butinpracticeitoftenleavesrailroadsinthepositionofdeterminingwhichcompanieswillflourishandwhichwillfail.”。由此，我们可以猜测出“arbiter”指的是“thosewhoareinthepositionofdeterminingsomething”，就可得出答案B。考生应知道，语言交流中，重复是一种常用的修辞手段，以强调某个信息或观点。文章中也常会利用重复手法。所以，考生猜测词义时不应只限于一个句子，而应从上下文寻找线索。D项虽有“determine”一词，但是意思不对。文中说的意思是，因为铁路对不同的顾客收取的费用不同，这种不公平使铁路公司无形中决定了托运商的命运（一些托运商的花费就会比其他托运商的高出很多，从而影响了他们的效益），所以铁路公司就好比是商场中的裁判，能决定谁赢谁输。D项的含义不准确。

第5题:该题为细节推断题，问的是铁路花费的上涨主要是用于什么事项。根据题干定位线索在最后一段，“Yetrailroadscontinuetoborrowbillionstoacquireoneanother…”，也就是说铁路还在不断借钱去收购合并，从这里得出答案为A，A是原文的转述，而B项，文中提到铁路公司还没有足够的钱去增加投资，以满足快速发展的交通的需要，但并不是引起成本提高的主要原因，文章的重点也不是交通的问题。C、D项在全文中均未有明显提及，是错误选项。

6.单选题

Thevitaminsareneededfor（

）foodsintoenergyandbodymaintenance.

问题1选项

A.shifting

B.transferring

C.altering

D.transforming

【答案】D

【解析】考查动词辨析。shift意为“转移，挪动”，指位置的改变，切换；transfer意为“转移，调动”，指的是转换工作、学习、搬迁等外在的改变，而物体自身并没有变；alter意为“改变，更改”，指替换（用一个替换另一个）；transform意为“改变”，指形状、外形的改变，物体本身自己形态的改变。

句意：维生素是将食物转化为能量和维持身体所必需的。

D.highlighttheproblemsoffooddeserts

【答案】第1题:A

第2题:C

第3题:B

第4题:D

第5题:A

【解析】1.语义推测题。根据第一段第三句fooddesertshavecometosymbolizeurbandecay（食物沙漠已经成为城市衰败的象征），可知食物沙漠与城市贫困直接相关，故A选项“与城市贫困直接相关”正确。B选项“是超重的直接原因”：根据第一段最后一句overweightcustomerswhohavenevertastedorganicvegetables（从未吃过有机蔬菜的超重顾客），可知文章没有提到超重和食物沙漠的因果关系。C选项“往往出现在贫困的农村地区”和D选项“指食物短缺的地方”：根据第一段第二句low-incomefamilieshavelittleornoaccesstohealthyfreshfood（低收入家庭很少或根本无法获得健康新鲜的食物）文章没有提到农村，也不是食物短缺。因此A选项正确。

2.语义推测题。根据第二段第一句Accordingly,MichelleObamaannounceda$400mHealthyFoodFinancingInitiativelastyearwiththeaimofeliminatingfooddesertsnationwideby2017.（因此，米歇尔•奥巴马(MichelleObama)去年宣布了一项4亿美元的健康食品融资计划，目标是到2017年在全国范围内消除食品沙漠。），可知其目的是让更多人吃到健康食品，故C选项“提高健康食品的份量”正确。A选项“解决日益增长的体重问题”不是目的。B选项“确保全国食品安全”文章没有提到食品安全。D选项“改变美国人的生活方式”涉及很多方面，不能仅仅通过某个方面的措施改变。因此C选项正确。

3.语义推测题。根据第二段第三句Althoughthismightonthefaceofitsuggestthattheinitiativeisofftoasuperbstart,sadlyitdoesnotinfactrepresentasingleadditionalbananaboughtorsodashunned.（虽然从表面上看，这可能意味着该倡议有了一个出色的开端，但令人遗憾的是，它实际上并没有多买一根香蕉或避免喝苏打水。），也许意味着有一个很好的开始，代表作者不持乐观态度，与D选项“至少是一个好的开始”的乐观态度不符，D选项错误；但遗憾的是，这并没有让人多买什么东西，作者认为这没多大作用，故B选项“没多大区别”正确，C选项“这代表真正的进步”错误。A选项“不是基于最新的信息”：文章没有提到数据是否是最新或是很早以前的。因此B选项正确。

4.语义推测题。根据第三段第一句Someacademicswouldgofurther,callingtheappearanceofmanyfooddesertsnothingbutamirage（一些学者甚至说许多食物沙漠不过是幻想），可知有学者不认同食物沙漠这个词的出现，故D选项“有问题的”正确，C选项“有道理的”错误。A选项“过时的”和B选项“创造性的”和本题无关。因此D选项正确。

5.主旨大意题。根据第四段第二句和第三句ThetownsitsinthemiddleofaUSDAfooddesert（该镇位于美国农业部的食品沙漠中心）…Yetitishometoaroadsidestandservingorganicfruitandvegetables,ahealth-foodshoppackedwithnutritiousgrainsandasuperstorethatresearchersfoundattractsflocksofshoppersfromwelloutsidethedesert.（然而，这里有一个卖有机水果和蔬菜的路边摊，一家摆满营养丰富的谷物的健康食品店，以及一家研究人员发现的吸引大批来自沙漠之外的消费者的超市。），结合文章开头美国农业部提出食物沙漠的定义，第三段作者提到自己认同的有学者提出食物沙漠是幻想的观点，可知作者认为食物沙漠这个现象不是大问题，不需要太过于重视，故C选项“提高公众对食物沙漠的认识”和D选项“强调食物沙漠的问题”错误；并且目的是让大家正确看待食物沙漠，故A选项“告诉我们要正确看待食物沙漠”正确。B选项“指出食物沙漠的解决方案”文章没有提到。因此A选项正确。

8.单选题

Thechild’sbadbehaviorisoftenmorethanawayoftryingto（

）hismother’sattentionawayfromhissister.

问题1选项

A.reflect

B.catch

C.deflect

D.reduce

【答案】C

【解析】考查动词辨析。reflect“反映”；catch“赶上，抓住”；deflect“使转向；转移”；reduce“减少”。虽然catchone’sattention是固定搭配，意思是“引起某人的注意”，但此处是“将某人的注意力转移”，因此选项B不正确，选项C符合题意。

9.单选题

Thesuspectgavea（

）explanationforhispresenceatthescene,sothepolicedecidedtolookelsewherefortheperpetratorofthecrime.

问题1选项

A.unbelievable

B.credible

C.insufficient

D.apologetic

【答案】B

【解析】形容词辨析题。unbelievable“不可信的，站不住脚的”；credible“可信的，可靠的”；insufficient“不充分的，不足的”；apologetic“道歉的，辩解的”；根据句意‘由于嫌疑人为自己在现场的出现做出了（

）解释，所以警察决定转向其它地方搜寻该犯罪的作案者。’确定B选项正确。

10.填空题

（1）hestudiedinAmericaforthreeyears,hecan’twriteEnglishverywell.Heisratherembarrassedbythisnow.He（2）hehadnotspentmoretime（3）hiswrittenEnglishwhilehewasabroad.

句意:尽管在美国学习过三年，但是他的英语书写能力却很差。这让他现在倍感尴尬。他说自己在国外时没有在书面英语上花较多的时间。

【答案】1.Although

2.said

3.on

【解析】1.逻辑分析。空格所在句子与其后面句子构成让步关系。

2.语义题。用said表示“说过”。

3.固定搭配。Spendtimeon花时间在某事上。

第5题:B

【解析】36.【试题答案】D

【试题解析】作者意图题。分析出作者是如何从华盛顿的轶事过渡到下文主题的，是本题的解题关键。纵观全文，从“华盛顿使用奴隶的牙”，到“华盛顿看到樱桃树的典型形象”，再到“奴隶制在开国元勋的生活中扮演的角色”可知，华盛顿是行文的线索，作者从讲述他鲜为人知的故事入手，引出话题，因此D选项“揭示了他生活中未知的一面”正确。

37.【试题答案】B

【试题解析】判断推理题。根据第二段第五句Worksofseveralhistoriansrevealthemoralcompromisesmadebythenation’searlyleadersandthefragilenatureofthecountry’sinfancy（几位历史学家的著作揭示了美国早期领导人做出的道德妥协，以及这个国家初期的脆弱本质）可推断出，B选项“在建国初期，美国面临着微妙的局势”正确。

38.【试题答案】C

【试题解析】事实细节题。根据第三段第二句WhileWashingtonandJeffersonprivatelyexpresseddistasteforslavery,theyalsounderstoodthatitwaspartofthepoliticalandeconomicbedrockofthecountrytheyhelpedtocreate（虽然华盛顿和杰斐逊私下里表达了对奴隶制的厌恶，但他们也明白，奴隶制是他们帮助创建的美国政治和经济基础的一部分）可知，虽然杰斐逊私下厌恶奴隶制，但也明白其政治生涯也得益于奴隶制，显然他对奴隶制的态度是复杂的，C选项正确。

39.【试题答案】A
