12.Engineering

13.C

14.B

15.InhisOffice．

16.whosewhose解析：此句意为“StephanieThomas，一位学习辅导老师，…发现已经发表了…。”由此可知，空处所填单词必为whose，引导定语从句，修饰teacher。

17.sellingselling解析：关键是看and后面的buying。本句话的意思是“商家分析市场的供需情况。”故答案为selling。

18.whosewhose解析：这是一个后置定语从句，用whose来引导，表示mind与dreamer的所属关系。故答案为whose。

19.dodo解析：解析见上题，为了避免与前面的know重复，这里可以换做do。故答案为do。

20.worseworse解析：“the+比较级，the+比较级”，意为“越…越…，”根据上下文，本句句意为“身边的小玩意儿越多，事情似乎就会变得越糟糕。”所以此处应填“worse”。

21.onon解析：dependenceon意为“依赖，依靠”，是固定短语。

22.sellingselling解析：关键是看and后面的buying。本句话的意思是“商家分析市场的供需情况。”故答案为selling。

23.outout解析：handout意为“分发，施舍”，为固定短语。

24.losinglosing解析：根据上下文的意思，很多年轻一代的日本人已经不再尊重父母，不再对家庭有责任感，所以这里用losing表示“渐渐失去了”。所以此处应填“losing”。

25.olderolder解析：grow只能是年龄越来越大。

26.A解析：文章第一句话对用基因疗法治疗Ashanthi所患罕见疾病的成功给与了很高的评价，并在第一段未指出医生们对基因疗法寄予了极高的期望。因此正确答案为A。

27.FF解析：由此空上下文可以看出，选项中只有F放在此处符合逻辑，上下文才能连贯。

28.C解析：由第二段中的“Second，theyhavetoadoptacomputersystemcalled…”可知。

29.DD解析：此处的前一段说明的是一些特殊情况，例如“Thesameistrueofthecrippledorphysicallyhandicapped．”而后面的一段指出“Ofcourse，theoppositeisalsotrue．”也就是说在空白的地方，作者依然在说明这些不寻常的情况，故应选D。

30.D解析：此题问技术员的回答如何。文章中“ButIdoneedit．”“Yes．butyoudon'thaveit．”Wewentonlikethisforawhile．Finally,heofferedtowalkmethrough…可以看出“技术员最后是在敷衍作者，没有提出一个合理的解决办法”。所以本题应选D。

31.AA解析：由上段的最后一句话“tookoverthehardphysicaltasksandrelievedthestrainonhumanandanimalmuscles．”可知答案为A，后面选项中的“thelaborthatrequiredthehumaneyes，ears，judgmentandmindbutnosweating”与之呼应，故应选A。

32.C解析：由全文可以推断，要指出犯罪率下降的确切原因是很困难的。

33.D解析：A、B、C项文中均没有提到。根据第三段的论述，可知D项是惟一正确的。

34.AA解析：由上下两段可知，只有A放在此处可以使上下文衔接，意思顺畅。

35.A解析：“这些区别”指的是什么?短文第五段主题句说“Butitisn’tallthateasytoexplaintheactualdifferencesbetweenskillsofmenandwomenonthisbasis．”即在此基础上解释两性技能的区别并不是很容易的事。由此可见，“这些区别”指的是两性技能。所以本题应选A。

36.A解析：文章第三段提到“TheAmericanideaofthenationalgoodhasneverbeenbasedonnationalcooperationbutratheronthefreedomoftheindividual,…．”这说明美国的国家利益不是建立在全民合作基础之上的，相反，这种基础是个人的自由。故应选A。

37.A解析：由A中的第一句话“‘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识到也许在四点的服务的原因是经过精心策划的而不是随意粗鲁的习惯，假期小费从随意的一句谢谢发展成为黑社会的保护勒索，所以作者是被迫的给假期小费的。因此正确答案为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“…所以建议所有人应该少吃盐没有意义。”可以推知，他的言下之意是“医生不应建议人们不吃盐”。

42.D文章最后一段指出，“Congressshouldpasslegislation…，allowcustomerstooptoutofsuchdatacollection，and…．”，意思就是说国会应该要求网站公示收集用户隐私信息的政策，通过何种方式收集的，告诉用户怎么才能避开这些信息收集以及怎么查阅所收集的信息等等内容。optout的意思是“避开、避免”。故应选D。

43.B文章最后一段第二句话“Competitionsometimesencouragesfeelingsofsuspicionratherthanthemutualtrustthatisnecessaryforsuccessfulnationalcooperation．”说明竞争有时会助长怀疑的意识，而不是合作需要的相互信任。故应选B。

44.BB第一段提到“…serveuphundredsofnewbuildingsthat．．．”。

45.A文章第三段第一句话“Yettherearcgoodreasonstoexpecttheeconomicconsequencesnowtobelessseverethaninthe1970s．”表明这次的油价上涨不会像以前那样带来严重的后果。从文章最后一段“0nemorereasonnottolosesleepovertheriseinoilpricesisthat，…”来看，我们不会为石油价格的上涨而失眠，也说明了这次的上涨影响不会很大。故应选A。2021年湖北省荆州市公共英语五级(笔试)模拟考试(含答案)学校:________班级:________姓名:________考号:________
