14、ThemostimportantroleindevelopingAIDSasapandemiawasplayedbysex

workers.

A、TRUE

B、FALSE

C、NOTGIVEN

標準答案：B

知識點解析：由developingAIDSasapandemia及sexworkers可知題目問性工作者

對艾滋病流行起到多大的影響，相關信息出現(xiàn)在第二段最后兩句。該處指出，貿(mào)

易、殖民主義的崩塌以及20世紀的社會政治改革對艾滋病的流行的影響與性工作

者的影響不相上下，并沒有比較哪個因素是最重要的，nolessimportant的表述與

題目Themostimportantrole不相符，故答案為FALSEo

15、ItisbelievedthatHIVappearedoutofnowhere.

A、TRUE

B、FALSE

C、NOTGIVEN

標準答案：B

知識點解析：考生易被第一段末句的outofnowhere干擾，但該句iIseemedto僅表

示推測，且由題目順序原則可知本題信息應在第二段后。第三段首句提到艾滋病病

毒并非憑空出現(xiàn)，與題目的表述“艾滋病病毒是憑空出現(xiàn)的“相反，故答案為

FALSEo

16、Humansarenotsocloselyrelatedtomonkeysastochimpanzees.

A、TRUE

B、FALSE

C、NOTGIVEN

標準答案：A

知識點解析：題目間人類基因與猴子及黑猩猩三者的密切程度，通過Humans、

monkeys以及chimpanzees可定位至第四段首句。該句指出，人類基因與猿類基因

的聯(lián)系要比與獗子基因的聯(lián)系更為密切(morecloselyrelatedtoapes)。其中插入語

likegorillasandchimpanzees是對apes的舉例說明，由此可知chimpanzees屬于

apes,故可推知題目所述符合文意，答案為TRUE。

17、HIV-1group0originatedin1920s.

A、TRUE

B、FALSE

C、NOTGIVEN

標準答案：C

知識點解析：文中提到HIV-1型O亞型組病毒的內(nèi)容僅有第四段最后兩句，該處

提到的信息主要有兩點。一是這種病毒的來源是猿類(originatingfromapes)；二是

這種病毒的感染人群集中在西非地區(qū)(humancasesarelargelyconfinedtowest

Africa)o文章并無提及其出現(xiàn)的時間點，故答案為NOTblVEN。

18、HIV-1groupMhassomethingspecial.

A、TRUE

B、FALSE

C、NOTGIVEN

標準答案：B

知識點解析：有關HIV-1型M亞型組病毒的信息出現(xiàn)在第五段至七段和第九段，

由題目HIV-lgroupM和special可定位至第六段首句。該處指出，HW-1型M亞

型組病毒可能并無任何特別之處，其中mightbenothingparticularlyspecialabout

groupM的表述與題Rhassomethingspecial相反，故答案為FALSEo

19、HumanDNAevolvesapproximately1milliontimesslowerthanHIV.

A、TRUE

B、FALSE

C、NOTGIVEN

標準答案：A

知識點解析：由HumanDNA及evolves可定位至第七段首句。該處指出RNA病毒

的進化速度比人類DNA的進化速度快了約一百萬倍，其中由suchas可知HIV為

RNA病毒的一種。1mi.liontimes是原詞重現(xiàn),而題H的slower與文中的faster雖

意義相反，但兩處主語分別為HumanDNA和RNAviruses,故題目表述與原文相

符，答案為TRUE。

20>ScientistsbelievethatHIValreadyexistedin1920s.

A、TRUE

B、FALSE

C、NO1GIVEN

標準答案：A

知識點解析：由HIV及1920s可定位至第七段第四句，該處提到HW-1型M亞型

組病毒最初是在20世紀20年代發(fā)展為流行病的。HW-1gro叩M是HIV的一種，

而題目1920s的時間點與原文一致，且只有病志已經(jīng)存在(alreadyexisted)才有可能

發(fā)展成流行病(pandemic),故題目表述與文章相符，答案為TRUE。

21、ScientistsspottedKinshasaastheoriginof

標準答案：thepandemic

知識點解析：看關Kinshasa的信息出現(xiàn)在第七、八段，結(jié)合origin可定位至第七段

末句，該處指出，F(xiàn)aria的團隊通過HIV的樣本發(fā)現(xiàn)艾滋病這一流行病源于金沙

薩。題目的scientists與文中they對應，theoriginof是原詞重現(xiàn)，故其后的賓語the

pandemic為答案。

22、Within20yearsthevirusmanagedtospreadtocities900milesawaywiththehelp

ofthe______

標準答案：railnetwork

知識點解析：題目中20years“一十年”和900mi1es“900英里”兩處數(shù)據(jù)較為醒目，

故可憑此定位至第八段末句。該處提到艾滋病病毒利用覆蓋面廣、客流量大的鐵路

網(wǎng)在僅僅20年里傳播到900英里外的城市。其中injust20years與題1=1Within20

years為同義表達;Takingfulladvantageof與withthehelpof相對應,故Takingfull

advantageof后的賓語是答案所在，考慮到題目的字數(shù)限制，答案為railnetwork。

23、ItwasthatmadeBelgianCongoapopulardestinationforemploymenttoFrench

speakers.

標準答案：independence

知識點解析：由BelgianCongo和populardestinationforemployments可柒位至第九

段第三句，該處指出，比屬剛果得到獨立后成為了對其他地方法語人口的熱門就業(yè)

地，其中attractivesourceofemployment與populardestinationforemployments為同

義表達。由題目可知空格處應填入名詞或名詞性短語，且其代表的事物對比屬剛果

成為法語人口的熱門就業(yè)地有促進作用，故答案為independenceo

24、HIVhasbeentransmittedrapidlythroughouttheUSandEuropebecauseofthe

標準答案：sociopoliticalsituation

知識點解析：由HIV和USandEurope可知題目關于艾滋病病毒在美國及歐洲的傳

播，可由此定位至第十段。該段第二句提到，艾滋病病毒利用了社會政治形勢在美

國及歐洲快速傳播,其中transmittedrapidlythroughouttheUSandEurope與spread

quicklythroughtheUSandEurope為同義表達。且由題目becauseof可知，空格處

應填入促進艾滋病耐毒在歐美傳播的事物(名詞或名詞性短語)，故答案應為took

advantageof'利用"后的賓語sociopoliticalsituationo

25、ItissaidthatoutbreakinIndianawasrelatedto

標準答案:druginjecting

知識點解析：由outbreakinIndiana可定位至第十一段末句，該處指出，美國印第

安納州的艾滋病爆發(fā)與毒品注射有關。題目outbreakinIndiana為原詞重現(xiàn)，related

to與文中associatedwith為同義表達，故答案應為associatedwith的賓語drug

injectingo

26、ThesamemethodasforHIVcanalsobeusedfor

標準答案:otherpathogens

知識點解析：由methodasforHIV可定位至第十三段首句3該句提到這一方法也可

用于其他病原體，Thisapproach即前文的analysingtheHIVgenomesequencesand

dataaboutlocationandtimeofinfection,與題目methodasforHIV相符，而題目be

usedfor與文中workfor為同義表達，故答案為workfor的賓語otherpathogenso

27、auseforheliumwhichmakesanactivitysafer

標準答案：C

知識點解析：由auseforhelium可知題目有關氮的用途，相關信息集中在C段。

該段最后一句提到，氨與氮混合能降低深海潛水時在高壓下吸人普通空氣的危險。

其中deep-seadiving符合題目activity的范疇.而makes…safbr”使...更安全''與

mitigatethedangersof...“降低...的危險”是同義表述,故題目與此處的信息相

符，答案為C。

28、thepossibilityofcreatinganalternativetohelium

標準答案：D

知識點解析：由analternativetohelium"氮的替代品”可定位至D段。該段首句提

到，即便人們有可能找到氨氣的替代品，也很難夏制其獨一無二的特性。其中if

notimpossibletoduplicate是對應題目的possibility,而ersatzproduct與alternative

為同義表達，故答案為D。

29、atermwhichdescribestheprocessofhowheliumistakenoutoftheground

標準答案：B

知識點解析：由howheliumistakenoutoftheground可知題目有關氮的提煉過程，

從而可定位至B段。該段末句提到，氨氣通過分饋法從地下的天然氣體儲藏中提

取出來。其中subterranean“地下的”與題目ground對應，takenoutof與extracted為

同義表達。method概括了題目howheliumistakenoutoftheground,故表示這一方

法名稱的fractionaldistillation即是題目term的具體所指，答案為B。

30、areasonwhyusersofheliumdonotmakeeffortstoconserveit

標準答案：E

知識點解析：由reason及donotmakeeffortstoconserve可知題Q有關氨氣沒有被

好好保存的原因，從而定位至E段。該段第三句提到，由于價值降低，天然氣提

煉商認為沒必要專門去油取氯氣。其中Deflatedvalues是題目reason的具體化，而

capture與conserve相對應，故答案為E。

標準答案：A

知識點解析：山題目chemicalproperties以及hownon-scientiststhinkaboutit可知有

關氮的化學性能及科學家以外的人對氮的認識，從而可定位至A段末句。該處指

出，氨是無味惰性的單原子元素，而行外人熟知的它是一種讓氣球飄浮在空中的氣

體，若吸入這種氣體人的聲音會變得尖銳。其中inert,odourless,monatomic

element是chemicalproperties的具體化，而laypeople對應non-scientists,故答案

為A。

32、Heliumchoosestobeonitsown,

A、YES

B、NO

C、NOTGIVEN

標準答案：A

知識點解析：由beonitsown可知題目關于使氫能獨立存在的屬性，相關信息集中

在D段。該段第四、3句提到，由于氮的電子結(jié)構(gòu)是閉合的，緊密地束縛著原

子，故它很難和其他元索結(jié)合。其中aclosedelectronic以及averytightlybound

atom是choosestobeonitsown的原因，而preventscombinationwithotherelements

與beonitsown相對應,故答案為YES。
