Thetopicofthepassagecanbestbegeneralizedas______.A.economiccrisisinAmericaB.medicareandsocialsecurityinAmericaC.American'sconsumptionconceptD.thePeterG.Petersonfoundation'sreport正確答案：B[解析]主旨題。文章從彼得·喬治·彼得森基金會(huì)關(guān)于美國(guó)“全民破產(chǎn)”的報(bào)告入手，分析了當(dāng)前的“福利神話(huà)”：旨在保障老年公民生活的社會(huì)與醫(yī)療保險(xiǎn)面臨嚴(yán)重危機(jī)。首先是政府準(zhǔn)備金不足，難以?xún)冬F(xiàn)賠付承諾；其次是當(dāng)代關(guān)國(guó)人享受的醫(yī)療與社會(huì)保險(xiǎn)屬于過(guò)度消費(fèi)，政府與個(gè)人“不負(fù)責(zé)任的借款”讓后代人不堪重負(fù)；再次是保險(xiǎn)金走向不理想：受損者得到賠償保障，但一大部分保險(xiǎn)金變成投保人的遺產(chǎn)(或許只是留給后代的不能兌現(xiàn)的支票)。保險(xiǎn)制度急需改革，但既可兌現(xiàn)承諾又可追回部分“盈余”保險(xiǎn)金的目標(biāo)幾乎不可能實(shí)現(xiàn)，改革陷入兩難，醫(yī)療與社會(huì)保險(xiǎn)陷入“搶劫”后代人的惡性循環(huán)。由此可見(jiàn)，只有B項(xiàng)抓住了核心議題：醫(yī)療與社會(huì)保險(xiǎn)。A項(xiàng)“經(jīng)濟(jì)危機(jī)”為語(yǔ)篇所處的大背景，C項(xiàng)“消費(fèi)觀”只是問(wèn)題的一部分；D項(xiàng)為開(kāi)篇之詞，易被解為“中心詞”，但實(shí)為文章“引子”。

Whichofthefollowingstatementmightbetheauthor'spointofviewon"weare'robbingfuturegenerations.'"?A.Wearerobbingfuturegenerationsthroughexcessiveconsumptionandirresponsibleborrowing.B.Wearerobbingfuturegenerationsbecausewhatweareleavingacountrywithheavyentitlementburden.C.Wearenotrobbingfuturegenerationsbecausewecannotstealavacationhomeormoneyfromtheyearof2050in2009.D.Wearenotrobbingfuturegenerationsbecauseweareleavinghundredsofthousandsofdollarstothenextgenerationinourwills.正確答案：A[解析]推斷題。文章第四段開(kāi)頭指出，人們認(rèn)為這種資不抵債的福利享受是在“搶劫后代”，作者認(rèn)為這種說(shuō)法“不完全正確”，因?yàn)椤澳愦_實(shí)不能從2050年偷一個(gè)度假屋，于2009年建在美麗的湖畔，也不能從2050年偷取或者借用金錢(qián)，在2009年花掉。”接著筆鋒一轉(zhuǎn)，指出“但你可以降低存款率，花掉你的積蓄，從而讓2050年的國(guó)家不再那么富有，也可以在2009年向外國(guó)借款，等他們?cè)?050年連本帶利一起要回，大家已經(jīng)在這么做了”。可以看出，作者認(rèn)為“我們的過(guò)度消費(fèi)與不負(fù)責(zé)任的借款是搶劫后代的行為”。

4.

Whatistheauthor'sattitudetowardsPeterG.Petersonfoundation'sreport?A.SkepticalB.ImpartialC.AffirmativeD.Derogatory正確答案：C[解析]態(tài)度題。文章第一段末尾提出根據(jù)彼得·喬治·彼得森基金會(huì)的報(bào)告，“看來(lái)我們已經(jīng)資不抵債了”。觀點(diǎn)并不明確；第二段段首提出假設(shè)：“如果這份報(bào)告是正確的，我肯定是玩完了，但這消息太糟糕了，簡(jiǎn)直難以置信”，但接著指出“細(xì)細(xì)考察，這確實(shí)是真的”，并以數(shù)據(jù)說(shuō)明?？梢?jiàn)作者對(duì)報(bào)告持肯定態(tài)度，C答案正確。

Theword"underscore"underlinedinParagraph1mostprobablymeans______.A.overestimateB.underestimateC.underlineD.underlie正確答案：C[解析]詞義題型。underscore此處意為“強(qiáng)調(diào)、凸顯”，A選項(xiàng)意為“高估”，B選項(xiàng)意為“低估”，C選項(xiàng)意為“強(qiáng)調(diào)”，D選項(xiàng)意為“構(gòu)成……的基礎(chǔ)或原因”，故選C。本題核心：1．充分利用上下文語(yǔ)境推測(cè)詞義；2．區(qū)分單詞之間的細(xì)微差異。本題中underscore、underline、underlie前綴相同，對(duì)三者表意異同的甄別要依賴(lài)于平時(shí)對(duì)常見(jiàn)常用詞匯的積累。

By"alittle-appreciatedbiologicalfact",theauthormeans______.A.mostpeoplearenotfamiliarwiththereproductionofdandelionsB.mostpeoplearenotfamiliarwithasexualreproductionC.sexualreproductionisseldomfavoredbybiologistsD.asexualreproductionisseldomfavoredbybiologists正確答案：B[解析]句子主旨題型。本題考察對(duì)文中特定句子主旨的理解?？疾炀湓谠~匯理解層面存在兩個(gè)關(guān)鍵點(diǎn)：一是appreciate一詞，該詞為大家所熟悉的義項(xiàng)是“感激，欣賞”，而此句適合的義項(xiàng)則是“知曉，領(lǐng)會(huì)”，整句可直譯為“一個(gè)鮮為人知的生物學(xué)事實(shí)”，C、D選項(xiàng)將appreciate錯(cuò)誤理解為favor，將biological一詞錯(cuò)誤理解為“生物學(xué)家的”，故先排除；二是fact一詞，該詞行使的是指代功能，此句本身未說(shuō)明所指，故需聯(lián)系上下文加以理解。從冠詞a一詞可判斷此概念在文中屬于首次提及，可推知具體的闡釋會(huì)出現(xiàn)在此句之前而非之后，而A選項(xiàng)“蒲公英的繁衍”出現(xiàn)在該句之前，為作者所要陳述事實(shí)的證據(jù)，故排除。緊隨其后的Contrarytohumanexperience,sexisnotessentialtoreproduction.一句對(duì)考察句進(jìn)一步加以解釋說(shuō)明，可見(jiàn)大多數(shù)人認(rèn)為性對(duì)于繁衍而言是必要條件，由此推定C選項(xiàng)“大多數(shù)人對(duì)無(wú)性繁衍不熟悉”符合作者的表意主旨。本題核心：留意常見(jiàn)詞匯的特殊義項(xiàng)，同時(shí)善于運(yùn)用語(yǔ)法知識(shí)鎖定正確的信息點(diǎn)所在。

9.

AccordingtoParagraph1,asexualreproductionisadvantageousforits______.A.largeoffspringnumbersB.creationofoffspringwithoutamateC.creationofgeneticallyidenticaloffspringD.creationofgeneticallydifferentoffspring正確答案：A[解析]段落主旨題型。本題考察點(diǎn)“無(wú)性繁衍的優(yōu)點(diǎn)”與段落的主旨密切相關(guān)。本段為全文引段，旨在點(diǎn)明主題。作者采用的具體策略是反面對(duì)照法，對(duì)照的兩方分別為有性和無(wú)性繁衍，意在通過(guò)彰顯無(wú)性繁衍的優(yōu)點(diǎn)來(lái)引發(fā)讀者思考有性繁衍存在的必要性。段中涉及無(wú)性繁衍的敘述有兩處，一是Theprodigiousspreadofthesewinsomeweeds，二是Asexualorganismscanoftenchurnoutmultiplegenerationsofclones,gainingadistinctedgeintheevolutionarynumbersgame.從prodigiousspread(瘋狂的傳播)、churnoutmultiplegenerations(大量制造子子孫孫)和numbersgame(數(shù)字游戲)等描述詞可見(jiàn)作者意在突出其繁衍數(shù)量多這一優(yōu)點(diǎn)，故選A。本題核心：B、C選擇項(xiàng)的內(nèi)容(無(wú)須交配；與后代基因相同)同樣屬于無(wú)性繁殖的特征，盡管在原文中亦有所提及，但甄選正確答案有賴(lài)于把握段落的論證邏輯，找準(zhǔn)表意重心，明確作者在此處提及無(wú)性繁殖的用意。

10.

Wecaninferfromthepassagethatsexfirstappearedin______.A.bacteriaB.multicellularorganismsC.rotestsD.protozoa正確答案：A[解析]細(xì)節(jié)題型。本題考察有性繁衍最早出現(xiàn)在哪種生物形態(tài)上。根據(jù)第二段第一句Sexalmostcertainlyoriginatednearly3.5billionyearsagoasamechanismforrepairingtheDNAofbacteria.中的originate一詞可基本鎖定A選項(xiàng)“細(xì)菌”。B選項(xiàng)中的organisms一詞同樣出現(xiàn)在第二段，但修飾詞unicellular被置換為multicellular，為干擾項(xiàng)。C選項(xiàng)rotests出現(xiàn)在第三段，對(duì)應(yīng)的時(shí)間點(diǎn)為1.5billionyearsago。D選項(xiàng)protozoa亦出現(xiàn)在第三段，對(duì)應(yīng)的時(shí)間點(diǎn)為modern。依次排序可確定A為正確答案。本題核心：此題涉及時(shí)間排序，可通讀全文尋找時(shí)間標(biāo)識(shí)詞確定答案。

WhichstatementisNOTtrueaboutconjugation?______A.Conjugationisaprocesswherebythegenesofbacteriaaretransferred.B.Conjugationisaprocesswherebythegenesofbacteriaarerecombined.C.Conjugationisaprocesswherebythegenesofbacteriaarerepaired.D.Conjugationisaprocesswherebythegenesofbacteriaaredamaged.正確答案：D[解析]概念主旨題型。此題考察對(duì)conjugation這一概念的理解。原文第三段將其描述為theintricateprocessinwhichonebacteriuminfusesgeneticmaterialintoanother(一個(gè)細(xì)菌將遺傳物質(zhì)注入另一個(gè)細(xì)菌的微妙過(guò)程)。選擇項(xiàng)并未照搬原文文字，因此需基于原文的描述把握概念的實(shí)質(zhì)。給出的四個(gè)選擇項(xiàng)分別為：在這個(gè)過(guò)程中，細(xì)菌的遺傳因子A“發(fā)生轉(zhuǎn)移”、B“進(jìn)行重組”、C“得到修復(fù)”、D“遭到損害”。A、B選項(xiàng)涉及過(guò)程描述，從定義本身可推定此兩選項(xiàng)無(wú)誤。C、D選項(xiàng)涉及結(jié)果/后果描述，從上下文可知，遠(yuǎn)古地球生存環(huán)境惡劣，細(xì)菌遺傳因子常因高熱和紫外線(xiàn)輻射而遭受損害，conjugation則提供了一種解決方案，可見(jiàn)結(jié)果應(yīng)當(dāng)是細(xì)菌的遺傳因子得到修復(fù)，C選項(xiàng)描述無(wú)誤。正確答案應(yīng)為D。本題核心：1．注意題干是以否定形式出現(xiàn)的，要求選出的是描述不正確的選項(xiàng)；2．不可因原文中出現(xiàn)damage原詞而斷章取義將其視為正確理解，而應(yīng)圍繞正確的邏輯關(guān)系作答。

12.

AccordingtobiologistLynnMargulis,______.A.rotestshavebotheggandspermcellsB.rotestsdevouredeachotherbecauseofstarvationC.rotestsdevouredeachotherforthesurvivalofitsspeciesD.protozoans,liketheirdistantancestors,devoureachother正確答案：B[解析]觀點(diǎn)主旨題型。本題考察生物學(xué)家LynnMargulis的具體觀點(diǎn)。原文給出的信息大意如下：精子和卵子產(chǎn)生的源頭可追溯到rotests。該類(lèi)生物因?yàn)轲囸I而相互吞噬，由于吞噬不完全，吞噬者和被吞噬者的細(xì)胞核發(fā)生了聚合。兩者的合力使得聚合后的細(xì)胞在惡劣環(huán)境中更容易存活，而這種相互結(jié)合的傾向也隨著其存活被其繼承下來(lái)。逐一對(duì)比選擇項(xiàng)可見(jiàn)：A選項(xiàng)與原文不符，盡管原文出現(xiàn)了roots一詞，但并非指rotests本身具有精子和卵子細(xì)胞，而是指這種生物在相互吞噬過(guò)程中產(chǎn)生了細(xì)胞核聚合，導(dǎo)致后來(lái)同類(lèi)生物之間精子和卵子細(xì)胞存在結(jié)合的傾向。C選項(xiàng)與原文不符，根據(jù)原文邏輯，“物種存續(xù)”是“互相吞噬”的結(jié)果而非原因。D選項(xiàng)與原文不符，盡管根據(jù)modernexamples一詞可判定protozoa和rotests之間存在共性，但原文protozoa一詞出現(xiàn)在作者探討rotests的吞噬現(xiàn)象之前，可見(jiàn)其共性并非吞噬本能，而只是從物種分類(lèi)上可大致劃歸一類(lèi)。本題核心：完整理解段落邏輯，而非孤立依據(jù)單獨(dú)字句斷章取義。

13.

Paragraph4impliesthathumansexualityistheresultof______.A.geneticmutationB.gradualevolutionC.germprotectionD.bacterialtransformation正確答案：B[解析]段落主旨題型。本題考察人類(lèi)性的來(lái)源，需準(zhǔn)確把握段落的論證邏輯。第四段開(kāi)頭前兩句提及了兩種截然相反的觀點(diǎn)，第一種認(rèn)為人類(lèi)性的出現(xiàn)可歸于偶然事件，第二種認(rèn)為人類(lèi)性的出現(xiàn)是為了存續(xù)逐漸進(jìn)化而來(lái)。從Fromthisvantagepoint一詞可知，第一種觀點(diǎn)是對(duì)上段內(nèi)容的總結(jié)，從however一詞可見(jiàn)本段論證重心發(fā)生轉(zhuǎn)變，之后整段的論述都圍繞后一種觀點(diǎn)展開(kāi)?？梢?jiàn)在A(基因突變)、B(逐漸進(jìn)化)、C(胚芽保護(hù))、D(細(xì)菌轉(zhuǎn)變)四個(gè)選項(xiàng)中，B是正確答案。本題核心：重點(diǎn)關(guān)注段落開(kāi)頭以有效把握主旨。

14.

Theword"elude"underlinedinParagraph4isclosestinmeaningto______.A.escapeB.confrontC.recognizeD.attack正確答案：A[解析]詞義題型。elude此處意為“逃避、逃開(kāi)”，A選項(xiàng)意為“逃避”，B選項(xiàng)意為“面臨、遭遇”，C選項(xiàng)意為“認(rèn)出、承認(rèn)”，D選項(xiàng)意為“攻擊”，故選A。本題核心：充分利用上下文語(yǔ)境推測(cè)詞義。

15.

ThefollowingcanbeinferredfromthepassageaboutsexualreproductionEXCEPT______.A.becauseofthemixingofgenesinsexualreproduction,alloffspringhavegeneticvariationsB.becauseofsexualreproduction,aspeciescanadaptmorequicklytochangesinitssurroundingsC.withthehelpofsexualreproduction,humansarebetterabletocombatbacteriaandspermsD.sexualreproductionleadstoagreatervarietyinpopulation正確答案：C[解析]是非題型。本題涉及對(duì)有性繁衍的描述，可采用排除法逐一考察。從第四段anovelmechanismforgeneratinggeneticallydifferentoffspring一句可知，A選項(xiàng)陳述無(wú)誤；從第三段thefusedcellswerebetterabletosurviveadversity、第四段increasingtheoddsthattheirprogenycouldexploitnewnichesinachangingenvironment等句可知，B選項(xiàng)陳述無(wú)誤；D選項(xiàng)“有性繁衍可使種群種類(lèi)更多樣”是基于原文信息的合理推斷。C選項(xiàng)對(duì)應(yīng)原文第四段的haveabetterchanceofsurvivingtheassaultsofbacteriaandothertinygerms一句，選擇項(xiàng)以sperms一詞替代原文中的germs一詞以混淆視聽(tīng)，故為有錯(cuò)選項(xiàng)。本題核心：重點(diǎn)關(guān)注選擇項(xiàng)的陳述細(xì)節(jié)，需與文中相應(yīng)字句一一對(duì)照以鎖定出錯(cuò)點(diǎn)。

16.

Thepurposeofthepassageisto______.A.justifythenecessityofsexualreproductionB.explaintheoriginofsexualreproductionC.tracethehistoryofsexualreproductionD.demonstratethedifferencesbetweensexualandasexualreproduction正確答案：A[解析]篇章主旨題型。本題考察全文主旨。文章除了開(kāi)頭，主干部分基本未提及無(wú)性繁殖，可見(jiàn)無(wú)性繁殖只是引子，不是作者的論證重心，由此排除D選項(xiàng)“闡釋有性繁衍和無(wú)性繁衍之間的差異”。其余三個(gè)選項(xiàng)總結(jié)的內(nèi)容原文均有涉及，需細(xì)讀原文考察作者的論證邏輯。從第一段最后一句Ifsexissuchaninefficientwaytoreproduce,whyisitsowidespread?(如果有性繁殖是低效的，為何會(huì)如此普遍?)可初步推定，作者的論證重點(diǎn)是有性繁殖存在的必要性。再考察隨后三段論證，盡管三段文字依次談到了生物、動(dòng)物以及人類(lèi)的有性繁殖，并在段落開(kāi)頭提及了三者的起源，但在具體論證過(guò)程中，突出的是有性繁殖發(fā)生的環(huán)境、原因以及生物進(jìn)化帶來(lái)的結(jié)果，可見(jiàn)“必要性”才是作者的論述主旨，應(yīng)選A。本題核心：應(yīng)同時(shí)關(guān)注兩方面內(nèi)容，一是文章的開(kāi)頭和結(jié)尾，二是具體段落的論證重點(diǎn)，以得出正確結(jié)論。
