15.BabyBoomgeneration

16.nono解析：本句話的意思是“那些趾高氣揚(yáng)的人不可能是那些平易近人的人”。這是否定的意思，故答案為no。

17.customercustomer解析：從這個(gè)句子的賓語(yǔ)“…thatheorshehasdoneagoodjobofchoosingtheitems．”可以看出，這里說(shuō)的是顧客的行為，他們認(rèn)為自己買這些商品是很理性的。故答案為customer。

18.wherewhere解析：此題考查where引導(dǎo)的定語(yǔ)從句，修飾前面提到的plane，trainorbus。所以此處應(yīng)填關(guān)系副詞“where”。

19.itit解析：本句意為“‘污染’意思是弄臟——表層土或什么東西，通過(guò)引進(jìn)雜質(zhì)，這使…不健康或不干凈。”顯然，此空處應(yīng)指topsoilorsomething，因?yàn)榍懊嬉殉霈F(xiàn)，所以用it來(lái)代替。

20.suchsuch解析：“poorposture，leaningtoo…tothedesk，using…”均是對(duì)characteristics的舉例說(shuō)明，而舉例用英語(yǔ)說(shuō)應(yīng)為“suchas”。

21.toto解析：talkto的意思是“和某人聊天”，talk這里不及物動(dòng)詞，后面需要接一個(gè)介詞。在從句中介詞不能省略。作者這里要表達(dá)的意思是“和那些誠(chéng)實(shí)的平易近人的人聊天是很愜意的?！惫蚀鸢笧閠o。

22.bringbring解析：通過(guò)前一句話“suchadreamercanbebroughtbacktoearth．”中的brought可以知道，這里應(yīng)該填bring，表示“把…帶到”。故答案為bring。

23.thosethose解析：本句的意思是“他們不認(rèn)為自己比別的不重要的人更好、更優(yōu)秀。”這里比較的是down-to-earthpersons和別人。故答案為those。

24.drinkingdrinking解析：由本句句意“通過(guò)將污水和化學(xué)物質(zhì)倒入河流和湖泊，我們已經(jīng)污染了我們的…水?！憋@然，此空處應(yīng)為“飲用”。

25.toto解析：“shift”意為“轉(zhuǎn)變”，“從…到…的轉(zhuǎn)變”應(yīng)該用介詞“to”。所以此處應(yīng)填“to”。

26.A解析：劃線單詞所在句子句意為“事情的另一面是：保險(xiǎn)公司已經(jīng)開(kāi)發(fā)了一些很有創(chuàng)造性的，能與其他替代產(chǎn)品，諸如投資競(jìng)爭(zhēng)的產(chǎn)品。它們能夠滿足任何一種全面投資計(jì)劃的需求?！笨梢?jiàn)“它們”即指“creativeandcompetitiveinsuranceproducts”。

27.CC解析：接下來(lái)講的是人體的免疫系統(tǒng)與毒藤之間的關(guān)系。毒藤會(huì)使人產(chǎn)生什么樣的反應(yīng)，該空緊接的就是毒藤過(guò)敏反應(yīng)時(shí)如何產(chǎn)生的?！癏ere'showthepoisonivyresponseoccurs．”一句承上啟下。所以本題應(yīng)選C。

28.D解析：文章最后一段指出，“Congressshouldpasslegislation…，allowcustomerstooptoutofsuchdatacollection．a(chǎn)nd…．”，意思就是說(shuō)國(guó)會(huì)應(yīng)該要求網(wǎng)站公示收集用戶隱私信息的政策，通過(guò)何種方式收集的，告訴用戶怎么才能避開(kāi)這些信息收集以及怎么查閱所收集的信息等等內(nèi)容。optout的意思是“避開(kāi)、避免”。故應(yīng)選D。

29.A解析：由A中的第一段最后一句話“Itassessestheimpactofpotentialfeatureglobalclimatechangeonagricultureandtheneedtosustainagriculturalgrowth…”可知。

30.A解析：由A中的第一段“Washington，thecapitaloftheUnitedStates，isinWashingtonD．C．”可知答案為A。

31.D解析：第一段最后一句話指出了疫苗短缺所暴露出來(lái)的問(wèn)題?！癟hisreemphasizesthefragilityofourvaccinesupply，”saysDr．MartinMyersoftheNationalNetworkforImmunizationInformation，“andthelackofredundancyinoursystem．”“這再次凸顯出我們疫苗供應(yīng)的脆弱性，”全國(guó)免疫信息網(wǎng)的馬丁·邁爾斯醫(yī)生說(shuō)，“此外，我們也沒(méi)有必要的補(bǔ)救機(jī)制。”因此正確答案為D。

32.B解析：有關(guān)商業(yè)方面的報(bào)道都是對(duì)Stiglitz的論點(diǎn)的支持信息?！啊璭speciallywhenthebusinesspageisfullofstoriesaboutwhite—collarcrimeandthestockmarketseemsstuckinaperpetualrut…”所以本題應(yīng)選B。

33.A解析：由第三段中所舉的GTE的例子可知“efficienttechnologyiscost-effective”。

34.EE解析：文章的最后一段中指出“averyfew”、“theelitefew”，而選項(xiàng)中的“averysmallgroupof‘scholars’”也正是指出了這種情況，故應(yīng)選E。

35.A解析：書(shū)評(píng)一中提到Stiglitz更主張政府參與下的經(jīng)濟(jì)政策，而不是以市場(chǎng)為主導(dǎo)的政策。所以本題應(yīng)選A。

36.A解析：第二段第二句“Mainlybecauseprivatecompanieshavehadlittleincentivetopursueit．”意思是說(shuō)“私企生產(chǎn)流感疫苗的積極性不高”。接下來(lái)作者介紹了制作疫苗的復(fù)雜工序，由此可以推斷出流感疫苗生產(chǎn)工藝復(fù)雜、成本高。第二段又明確指出了私企不愿意生產(chǎn)流感疫苗的其他原因：利潤(rùn)率低、需求不穩(wěn)定、此外由于流感病毒每年都不同，因此生產(chǎn)數(shù)量不能過(guò)大，由此也可推斷出生產(chǎn)的風(fēng)險(xiǎn)性大，如果生產(chǎn)多了就會(huì)損失很大。因此正確答案為A。

37.D解析：第四段提到基因療法遭受的一起挫折——一個(gè)病人因接受基因療法而死亡；接著講專家擔(dān)心運(yùn)動(dòng)員利用基因在比賽中作弊會(huì)進(jìn)一步tarnish這一領(lǐng)域，從上下文邏輯推理，應(yīng)該是“有損，玷污”這一類的意思，因此正確答案為D。

38.D解析：文章的結(jié)尾，作者說(shuō)我們不知道學(xué)校學(xué)生的能力和大腦兩半球功能之間的確切關(guān)系；我們不懂大腦兩半球是如何通過(guò)corpuscallosum相互作用的；間接地提出對(duì)于corpuscallosum的影響，多作研究工作。所以本題應(yīng)選D。

39.B解析：由B中的第一段“NewYorkCity，locatedinNewYorkState．isthelargestcityandthechiefportoftheUnitedStates．”可知答案為B。

40.D解析：第二段第一句提到“…butoldwastefulhabitsdiehard”，可知雖然美國(guó)人開(kāi)始回收利用一些物品，但是那種浪費(fèi)的舊習(xí)慣依然不好消除。最后一句話“…itcanbecomestrongeronlyasAmericansseetheneedforitmoreclearly．”也說(shuō)明了只有當(dāng)美國(guó)人真正意
