參考答案

1.pricedifferencespricedifferences解析：參見(jiàn)“TheMainEconomizingPractices”小節(jié)最后一句話：Althoughqualitydifferences...oftencontributetopricesdifferences，differencesinnutritionalqualityarealsoevident．(食品營(yíng)養(yǎng)含量的不同對(duì)價(jià)格的影響還是很明顯的。)inaccordancewith與……一致。

2.B解析：文章第四自然段第三句...，itisoneimportantvariablethat...，人口激增是一個(gè)導(dǎo)致發(fā)達(dá)國(guó)家與發(fā)展中國(guó)家的貧富差距擴(kuò)大的一個(gè)重要的變數(shù)，而非唯一的因素。

3.designstagedesignstage解析：參看GlobalSolution部分的第二段第一句話“Ifwe'reseriousaboutaddressingourwasteproblems，weneedtostartworkatthedesignstageofaproduct'slifecycle．”，說(shuō)明如果我們要認(rèn)真對(duì)待廢物處理問(wèn)題就需要在產(chǎn)品的設(shè)計(jì)階段著手工作。

4.A解析：見(jiàn)文章倒數(shù)第四段第一句話。

5.veryspecializedneedsveryspecializedneeds解析：由題干中certainfield可定位到第六個(gè)小標(biāo)題下末句Becomethepersonpeoplehavetogotowhentheyhaveveryspecializedneeds，becauseyou'retheonlyonethatdoesit.此處，certainfield和specializedneeds呼應(yīng)。此處要求填入名詞性短語(yǔ)，作have的賓語(yǔ)。本題考查精于專(zhuān)業(yè)知識(shí)的意義。根據(jù)原句可知，精于專(zhuān)業(yè)知識(shí)，當(dāng)人們有這方面的專(zhuān)門(mén)需求時(shí)，便會(huì)受人青睞。因此原句中when引導(dǎo)的狀語(yǔ)從句賓語(yǔ)即為本題答案。

6.C解析：題干考查的是兩年前導(dǎo)致非洲玉米主要食物損失一半以上的原因。根據(jù)定位句，可以找出題干中所指的mainfood指的是文章中的akeysourceofcalories，即cassavacrop；因此，根據(jù)定位句可知這一損失是由themosaicvirus引起的。所以本題答案為C。

7.A解析：根據(jù)原文可知有超過(guò)80％的重性抑郁癥患者能得到治療，但是他們中的大部分卻沒(méi)有尋求治療，也就是說(shuō)大部分人都沒(méi)有足夠地重視自己所患的抑郁癥，故本題答案為Y。

8.farmingfarming解析：同義轉(zhuǎn)述題。題干把原文中的“農(nóng)業(yè)是主要的工作”變成了“大多數(shù)人通過(guò)___謀生”，用詞不同，但意思沒(méi)有兩樣。因此，空格處填farming。

9.withachargeofmutiny(or.tobechargedwithmutiny)withachargeofmutiny(or.tobechargedwithmutiny)

10.federalincometaxfederalincometax解析：由題干關(guān)鍵詞withheldfromthepaycheck可將答案定位至第三個(gè)小標(biāo)題下第二段第五句。Theinformationonthisform.tellsyouremployerjusthowmuchmoneyitneedstowithholdfromyourpaycheckforfederalincometax,劃線部分就是答案。

11.A解析：原文表明HenrikChristensen很關(guān)心機(jī)器人的security和safety方面的問(wèn)題，也就是說(shuō)，他認(rèn)為機(jī)器人應(yīng)該首先對(duì)人不會(huì)構(gòu)成安全上的威脅；即harmless，因此本題應(yīng)選A。

12.professionalhelpprofessionalhelp解析：空前的provide表明，本空應(yīng)填一名詞或名詞短語(yǔ)。該句提到，如果你覺(jué)得自己的問(wèn)題嚴(yán)重，可以從心理醫(yī)生、精神科醫(yī)生或社會(huì)工作者那兒尋求專(zhuān)業(yè)援助。由此可知，心理醫(yī)生或社會(huì)工作者提供的是專(zhuān)業(yè)援助，故答案為professionalhelp。

13.itsownclimaticsystemsitsownclimaticsystems解析：根據(jù)題干中的信息詞Antarctica、immune和insulated定位到第三個(gè)小標(biāo)題下的最后一段，可知南極大體上不受全球趨勢(shì)的影響，而且南極非常大，可以形成自己的氣候體系，所以南極大部分現(xiàn)在似乎還沒(méi)有融化，由此可得答案。

14.peer-to-peerfilesharingpeer-to-peerfilesharing解析：從“Anenhancedversionoftheservicewillusepeer-to-peerfile-sharingtechnologytogetthevideodatatoviewers.”可以得到答案。

15.NGNG解析：第一個(gè)小標(biāo)題下的最后一點(diǎn)建議提到，不要忘記說(shuō)“再見(jiàn)”，如果你沒(méi)有和剛剛遇到的人說(shuō)“再見(jiàn)”，就會(huì)給別人留下不好的印象，但原文并投有提到不說(shuō)“謝謝”會(huì)有怎樣的后果。

16.A解析：本題根據(jù)自然段第一句而設(shè)，blanketterm為“統(tǒng)稱(chēng)”，與coverterm是同義詞。題目中的縮寫(xiě)是很好的搜索關(guān)鍵詞。

17.thegymthegym解析：該段提到，Thegymcanbe…somewheretoexerciseondayswhenyoucan'tfacethecoldortherain(在你無(wú)法忍受的寒冷和下雨的日子里，體育館是個(gè)鍛煉的好地方)，由此可以推斷出，如果一個(gè)人想在下雨天鍛煉，應(yīng)該是去體育館。此外，本題所設(shè)的空在句中，所以注意所填詞均為小寫(xiě)。

18.itsownclimaticsystemsitsownclimaticsystems解析：根據(jù)題干中的信息詞Antarctica、immune和insulated定位到第三個(gè)小標(biāo)題下的最后一段，可知南極大體上不受全球趨勢(shì)的影響，而且南極非常大，可以形成自己的氣候體系，所以南極大部分現(xiàn)在似乎還沒(méi)有融化，由此可得答案。

19.alcoholismandracismalcoholismandracism解析：參見(jiàn)“PossibleCausesforSuicide”小節(jié)部分第3段第3句：Suicideisespeciallyhighamongthemostmarginal.,youngAboriginalmen,isolatedbypoverty,alcoholismandracism.

20.muchabouttherestofEuropemuchabouttherestofEurope解析：根據(jù)題干中的信息詞Swissspaghettiharvest定位到第五個(gè)小標(biāo)題，該部分最后一段提到，Boese表示，英國(guó)人不太了解歐洲其他國(guó)家。再結(jié)合上文可知，這正是許多英國(guó)人相信瑞士的意大利面條大豐收的原因。

21.C解析：W:Hi,Bob.Comein.I'mgladyoucouldmakeittothepartythisevening.Where'sJane?
