16.whosewhose解析:此句意為“StephanieThomas,一位學(xué)習(xí)輔導(dǎo)老師,…發(fā)現(xiàn)已經(jīng)發(fā)表了…?!庇纱丝芍?,空處所填單詞必為whose,引導(dǎo)定語從句,修飾teacher。
17.sellingselling解析:關(guān)鍵是看and后面的buying。本句話的意思是“商家分析市場的供需情況。”故答案為selling。
18.whosewhose解析:這是一個后置定語從句,用whose來引導(dǎo),表示mind與dreamer的所屬關(guān)系。故答案為whose。
19.dodo解析:解析見上題,為了避免與前面的know重復(fù),這里可以換做do。故答案為do。
20.worseworse解析:“the+比較級,the+比較級”,意為“越…越…,”根據(jù)上下文,本句句意為“身邊的小玩意兒越多,事情似乎就會變得越糟糕?!彼源颂帒?yīng)填“worse”。
21.onon解析:dependenceon意為“依賴,依靠”,是固定短語。
22.sellingselling解析:關(guān)鍵是看and后面的buying。本句話的意思是“商家分析市場的供需情況?!惫蚀鸢笧閟elling。
23.outout解析:handout意為“分發(fā),施舍”,為固定短語。
24.losinglosing解析:根據(jù)上下文的意思,很多年輕一代的日本人已經(jīng)不再尊重父母,不再對家庭有責(zé)任感,所以這里用losing表示“漸漸失去了”。所以此處應(yīng)填“l(fā)osing”。
25.olderolder解析:grow只能是年齡越來越大。
26.A解析:文章第一句話對用基因療法治療Ashanthi所患罕見疾病的成功給與了很高的評價,并在第一段未指出醫(yī)生們對基因療法寄予了極高的期望。因此正確答案為A。
27.FF解析:由此空上下文可以看出,選項中只有F放在此處符合邏輯,上下文才能連貫。
28.C解析:由第二段中的“Second,theyhavetoadoptacomputersystemcalled…”可知。
29.DD解析:此處的前一段說明的是一些特殊情況,例如“Thesameistrueofthecrippledorphysicallyhandicapped.”而后面的一段指出“Ofcourse,theoppositeisalsotrue.”也就是說在空白的地方,作者依然在說明這些不尋常的情況,故應(yīng)選D。
30.D解析:此題問技術(shù)員的回答如何。文章中“ButIdoneedit.”“Yes.butyoudon'thaveit.”Wewentonlikethisforawhile.Finally,heofferedtowalkmethrough…可以看出“技術(shù)員最后是在敷衍作者,沒有提出一個合理的解決辦法”。所以本題應(yīng)選D。
31.AA解析:由上段的最后一句話“tookoverthehardphysicaltasksandrelievedthestrainonhumanandanimalmuscles.”可知答案為A,后面選項中的“thelaborthatrequiredthehumaneyes,ears,judgmentandmindbutnosweating”與之呼應(yīng),故應(yīng)選A。
32.C解析:由全文可以推斷,要指出犯罪率下降的確切原因是很困難的。
33.D解析:A、B、C項文中均沒有提到。根據(jù)第三段的論述,可知D項是惟一正確的。
34.AA解析:由上下兩段可知,只有A放在此處可以使上下文銜接,意思順暢。
35.A解析:“這些區(qū)別”指的是什么?短文第五段主題句說“Butitisn’tallthateasytoexplaintheactualdifferencesbetweenskillsofmenandwomenonthisbasis.”即在此基礎(chǔ)上解釋兩性技能的區(qū)別并不是很容易的事。由此可見,“這些區(qū)別”指的是兩性技能。所以本題應(yīng)選A。
36.A解析:文章第三段提到“TheAmericanideaofthenationalgoodhasneverbeenbasedonnationalcooperationbutratheronthefreedomoftheindividual,….”這說明美國的國家利益不是建立在全民合作基礎(chǔ)之上的,相反,這種基礎(chǔ)是個人的自由。故應(yīng)選A。
37.A解析:由A中的第一句話“‘Bewitched’isapainfullyembarrassingremakeoftheclassicTVsitcomthatranonABCfrom1964-1972.”可知。
38.A解析:由文章第四段中的“Anotherfamousexampleistheelectrical.Thisfishgivesanevenmorepowerfulshock.”可知。
39.D解析:在第三段中女主人公意識到也許在四點的服務(wù)的原因是經(jīng)過精心策劃的而不是隨意粗魯?shù)牧?xí)慣,假期小費從隨意的一句謝謝發(fā)展成為黑社會的保護勒索,所以作者是被迫的給假期小費的。因此正確答案為D。
40.C解析:由第三段最后一句“Lifeinsuranceisan…isnotsubjecttotaxes,incontrasttootherpersonalinvestments.”可知。
41.B第三段中Dr.Laragh提到“…所以建議所有人應(yīng)該少吃鹽沒有意義?!笨梢酝浦?,他的言下之意是“醫(yī)生不應(yīng)建議人們不吃鹽”。
42.D文章最后一段指出,“Congressshouldpasslegislation…,allowcustomerstooptoutofsuchdatacollection,and….”,意思就是說國會應(yīng)該要求網(wǎng)站公示收集用戶隱私信息的政策,通過何種方式收集的,告訴用戶怎么才能避開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、避免”。故應(yīng)選D。
43.B文章最后一段第二句話“Competitionsometimesencouragesfeelingsofsuspicionratherthanthemutualtrustthatisnecessaryforsuccessfulnationalcooperation.”說明競爭有時會助長懷疑的意識,而不是合作需要的相互信任。故應(yīng)選B。
44.BB第一段提到“…serveuphundredsofnewbuildingsthat...”。
45.A文章第三段第一句話“Yettherearcgoodreasonstoexpecttheeconomicconsequencesnowtobelessseverethaninthe1970s.”表明這次的油價上漲不會像以前那樣帶來嚴重的后果。從文章最后一段“0nemorereasonnottolosesleepovertheriseinoilpricesisthat,…”來看,我們不會為石油價格的上漲而失眠,也說明了這次的上漲影響不會很大。故應(yīng)選A。2021年湖北省荊州市公共英語五級(筆試)模擬考試(含答案)學(xué)校:________班級:________姓名:________考號:________
