Shewasso（

）inherworkthatshedidn’tnoticemewhenIcameintheroom.

問題1選項

A.immersed

B.obsessed

C.submerged

D.suffocated

【答案】A

【解析】考查固定搭配。A選項通常用于beimmersedin（沉浸于，埋頭于，陷入）；B選項通常用于beobsessedwith（癡迷于，著迷于）；C選項submerge“浸沒，淹沒”；D選項suffocate“（使）窒息而死，（把……）悶死”。句中的so...that表示“如此……以至于”，根據(jù)固定搭配和后面的shedidn’tnoticemewhenIcameintheroom（我走進(jìn)房間時她沒注意到我）可知她沉浸于工作中，以至于沒注意到我進(jìn)來，因此選A。句意：她如此沉浸于工作中，以至于我進(jìn)屋時她都沒有注意到我。

【答案】1.縱觀美國歷史，幾乎總是至少會有一個經(jīng)濟(jì)中心的故事，讓雄心勃勃或不滿足的人有理由收拾行囊，到別處去尋找機(jī)遇。在歐洲人定居的前300年左右，這種故事是關(guān)于人口向外遷移的：讓移民先到大陸，然后再到邊疆開辟草原，排干濕地，并建造新的城市。

2.如果沒有新的土地可以征服，這個精力充沛、富有進(jìn)取精神的國家將會怎樣？有些人，比如泰迪?羅斯福，決定繼續(xù)征服(古巴、菲律賓等地)，但最終，在工業(yè)化的進(jìn)程中，美國在國內(nèi)發(fā)現(xiàn)了一個新的關(guān)于經(jīng)濟(jì)流動的故事。

3.而且這些行業(yè)的規(guī)模足夠大，可以為各個階層的工人提供工作，從非技術(shù)工人到經(jīng)理或工程師。但是今天，我們經(jīng)濟(jì)中為數(shù)不多的亮點相對較小(盡管一些亮點未來可能會增長)，而且是分散管理的。

4.順便說一下，你不需要成為下一個Facebook的創(chuàng)始人馬克?扎克伯格(MarkZuckerberg)，也能在微軟中心找到一份工作。但幾乎可以肯定的是，你至少需要計算機(jī)科學(xué)學(xué)士學(xué)位或在技術(shù)學(xué)校待過一兩年。這個新興的擇業(yè)市場是全國性的，它為流動階層的成員提供了有競爭力的薪資和更高的議價權(quán)力。

5.他稱，盡管那些頂尖大學(xué)的畢業(yè)生不論他們學(xué)的專業(yè)是什么，都有可能找到一份好工作，但那些不知名學(xué)校的畢業(yè)生將會根據(jù)他們所學(xué)的知識來接受評判。為了在全國范圍內(nèi)競爭工作崗位，他們應(yīng)該具備新興產(chǎn)業(yè)所需要的技能，無論是技術(shù)性的還是非技術(shù)性的。

10.單選題

Someoneisringingthedoorbell.Goandsee______.

問題1選項

A.whoishe

B.whoitis

C.whoheis

D.whoisit

【答案】C

【解析】【選項釋義】

A.whoishe他是誰B.whoitis它是誰

C.whoheis他是誰D.whoisit它是誰

【考查點】賓語從句。

【解題思路】分析句子可知，空格處為賓語從句，跟在動詞go和see的后面，根據(jù)前一句“有人在按門鈴”可知，賓語從句引導(dǎo)要用who，從句要用陳述語氣，who指的是someone，所以要用代詞he，該題選擇C項正確。

【干擾項排除】

A、D項不是陳述語氣；

B項it不指人。

【句意】有人在按門鈴。去看看他是誰。

11.單選題

Ajobdescriptionshouldgivedetailsoftheperformance______aspecificjob.

問題1選項

A.thatisrequiredfor

B.thatrequired

C.thatrequires

D.requiringfor

【答案】A

【解析】考查定語從句。根據(jù)句子結(jié)構(gòu)和句意，先行詞performance在定語從句中是require的邏輯賓語，是被要求具備的，要用被動語態(tài)；C、B、D均為主動語態(tài)；本句句意是：工作描述應(yīng)詳細(xì)說明具體工作所需的表現(xiàn)。因此選A。

【答案】第1題:D

第2題:A

第3題:B

第4題:C

第5題:B

【解析】1.主旨大意題。文章通篇都是在討論科學(xué)研究或探索的方法。

2.細(xì)節(jié)題。第四段指出:Theattempttodiscovertheexplanationofthishenomenonintheantithesisof"facts"and"theories"or"facts"and"ideas"-intheneglectamongtheancientsoftheformer,andtheirtooexclusiveattentiontothelatter-provesalsotobetoonarrow,aswellasopentothechargeofvagueness.Forinthefirstplace,theantithesisisnotcomplete.Factsandtheoriesarenotcoordinatespecies.試圖在事實的對立面和理論，或事實和思想中發(fā)現(xiàn)上述現(xiàn)象的解釋看起來有些太狹隘，也會因模糊不清遭批評。因為，對立面不全面，事實和理論不是同類的事物。第五段指出：Afactisapropositionofsimple.Atheory,ontheotherhand,iftruehasallthecharacteristicsofafact,exceptthatitsverificationispossibleonlybyindirect,remote,anddifficultmeans.Toconverttheoriesintofactsistoaddsimpleverification,andthetheorythusacquiresthefullcharacteristicsofafact.事實是一個提議，通過運(yùn)用知識的源泉和經(jīng)驗而證實的提議直接而又簡單。而理論，若是真理論，就有事實的一切特性（除非其證實只能通過非直接的，遙遠(yuǎn)的和困難的方式方法），把理論轉(zhuǎn)成事實必須用簡單的核實，理論因此具有事實的一切特性。由此得出，選擇A:后者(理論)需要證實。

3.推斷題。文章指出:事實和理論不是同類的事物。因此“理論即事實”的論斷就是悖論。故B項正確。

4.推斷題。選項C推理演繹科學(xué)正確。

5.細(xì)節(jié)題。第一段指出：Orshouldweascribethecharacteristicsofbothperiodstoso-calledhistoricalaccidents-totheinfluenceofconjunctionsincircumstancesofwhichnoexplanationispossible,saveintheomnipotenceandwisdomofaguidingProvidence?或者，我們是否應(yīng)該把這兩個時期的特征都?xì)w因于所謂的歷史意外事件一一歸因于客觀環(huán)境中相似性結(jié)合的影響。這一點除非以指導(dǎo)一切的上帝的智慧和無限權(quán)利來解釋，否則難以解說清楚。因此B項:是上天的安排為正確選項。

13.單選題

EnglishisthedominantlanguageinHawaii,butitisinfusedwithHawaiianwords,phrasesandpidginslang.

問題1選項

A.included

B.affected

C.filled

D.spoiled

【答案】C

【解析】【選項釋義】

A.included包括，包含B.affected影響

C.filled（使）充滿，裝滿D.spoiled破壞，搞壞，毀掉

【答案】C

【考查點】動詞辨析。

【解題思路】infused的意思為“使具有，注入（某特性）”，這里指夏威夷主要講英語，但在英語中有非常多的夏威夷詞匯、短語和洋涇浜俚語，filled與之詞義相近，因此C選項正確。

【干擾項排除】A、B、D選項詞義與之不符。

【句意】英語是夏威夷的主導(dǎo)語言，但它滿是夏威夷詞匯、短語和洋涇浜俚語。

14.單選題

問題1選項

B.asserts

C.boasts

D.toasts

【答案】A

【解析】考查動詞辨析。exaggerate“夸大”；assert“斷言”；boast“吹噓”。exaggerate符合句意。本句意為“他為他的孩子們而感到驕傲，他經(jīng)?？浯笏麄兊男〕删汀保虼薃選項正確。

15.單選題

Somedaysoftwarewilltranslatebothwrittenandspokenlanguagesowellthattheneedforanycommonsecondlanguagecould（）.

問題1選項

A.descend

B.decline

C.deteriorate

D.depress

【答案】B

【解析】考查動詞辨析。A選項descend“下降”，多指從高處落向低處；B選項decline“衰退”，多指數(shù)量，質(zhì)量或價值的下降；C選項deteriorate“惡化，變壞”；D選項depress“壓抑，使沮喪”。根據(jù)句意：總有一天，軟件可以很好地翻譯書面語和口語，以至于對通用第二語言的需求可能會減少。這里是指需求減少，所以選項B最恰當(dāng)。

【答案】第1題:D

第2題:B

第3題:C

第4題:B

第5題:C

【解析】第1題:事實細(xì)節(jié)題。根據(jù)第三段的第三句"OfallthewealthrepresentedontheForbes400list,morethanhalfisinherited."福布斯富人榜中，富人的財富大部分是繼承而來的。所以選項D正確。

第2題:事實細(xì)節(jié)題。根據(jù)第四段的一二句“Theuppermiddleclassincludesthosewithhighincomesandhighsocialprestige.Theytendtobewell-educatedprofessionalsorbusinessexecutives.”上層中產(chǎn)階級包括那些收入高、社會地位高的人。他們往往是受過良好教育的專業(yè)人士或企業(yè)高管。所以選項B正確。

第3題:事實細(xì)節(jié)題。根據(jù)第五段的倒數(shù)第二句“...peopletendnottowanttorecognizeclassdistinctionsintheUnitedStates.”人們不愿意承認(rèn)在美國存在著階級差別。選項C符合原文。

第4題:根據(jù)最后一段的一二句"Thelowerclassis...poor.Peopleinthisclasshavelittleformaleducationandareoftenunemployedorworkinginminimum-wagejobs."下層階級主要由流浪者和窮人組成。這個階層的人幾乎沒有受過正規(guī)教育，經(jīng)常失業(yè)或從事最低工資的工作。由此可推斷，下層階級從事的工作不需要太高的受教育程度。選項B正確。

第5題:根據(jù)最后一段的最后一句“Rejectedfromtheeconomicsystem,thoseintheunderclassmaybecomedependentonpublicassistanceorillegalactivities.”被排斥在經(jīng)濟(jì)體系之外的下層階級可能會依賴于公共援助或非法活動。句中的publicassistanceorillegalactivities與C選項中的bywelfareorcrime同義。所以選項C符合原文。
