28、 the United States history.（分数：2.00）A.ageB.epochC.eraD.time专业英语四级-21答案解析 (总分：100.00，做题时间：90分钟)一、GRAMMAR AND VOCABULA(总题数：60，分数：100.00)1.Which of the following words can NOT be used to complete I _ think so?（分数：1.50）A.seldomB.hardlyC.evenD.rare解析：解析 考查副词用法。seldom“较少”，hardly“几乎不”和even“甚至”都符合句意，但rare作副
29、词常在口语中，意为“非常”，若要填入此空，则需用rarely。2._ Mike! I knew he would get the first prize in the race.（分数：1.50）A.Thank goodnessB.Goodness knowsC.Good oldD.Thanks解析：解析 good old后接人名，如good old Mike/William表示对某人(不负众望)的行为表示称赞，C为正确答案。3.By the time you graduate from college, we _ in Australia for one year.（分数：1.50）A.wi
30、ll be stayingB.will have stayedC.would have stayedD.have stayed解析：解析 根据句意，graduate这一动作还未发生，而且“在澳洲居住满一年”是在将来的某一时间完成的，因此主句要用将来完成时，答案为B。将来完成时常和“by the time+句子”的结构连用。4.It is because of a rise in air fares _ theyve surcharged us 10% on the price of the holiday.（分数：1.50）A.thatB.whichC.whatD.that which解析：解
31、析 考查强调句式“It is+名词/代词/介宾短语/从句等强调部分+that从句”，因此答案为A。题中强调部分是because of a rise in air fares，正常语序是Theyve surcharged us 10% on the price of the holiday because of a rise in air fares.5.He must have gone to the cinema last night, _?（分数：1.50）A.mustnt heB.hasnt heC.isnt heD.didnt he解析：解析 must have done是对过去的肯定
32、推测，当陈述部分为must表示推测时，反意疑问句部分不用must，而是根据陈述部分的谓语动词采用相应的系动词或助动词。这里谓语动词是go，句中表示的是过去的时间，因此用didt。6.Which of the following sentences expresses probability?（分数：1.50）A.You must have your hair cut by ten oclock.B.You must be in the office tomorrow.C.You must complete the work tonight.D.You must be feeling bette
33、r now.解析：解析 考查情态动词must的用法。must除了表示“必须”之义外，还可以表示“推测/猜测”之义，如：You have worked hard all day. You must be tired now. (表示对现在的推测) I didnt hear the phone. I must have been asleep. (表示对过去的推测)。A、B、C均表示一种命令，只有D“你现在应该感觉好多了吧”表示推测，故为正确答案。7.Evidence came up _ animals will behave abnormally if there is going to be
34、an earthquake.（分数：1.50）A.whichB.whatC.thatD.whose解析：解析 这里应该填入同位语从句引导词that，从句和Evidence之间被谓语动词came up隔开，其他选项在句中找不到其先行词，因此不能选。8.Do try your best to finish it, _ you?（分数：1.50）A.cantB.dontC.wouldntD.wont解析：解析 祈使句的附加疑问句。肯定的祈使句表示“请求”时，反意疑问句一般用will you，如：Give me a hand, will you?表示“邀请、劝诱”时，反意疑问句则用wont you,
35、如：Have another piece of cake, wont you?在否定的祈使句中，疑问句部分只用will you。“尽最大努力完成它”表劝诱，故答案为D。9.You _ her the truth. It didnt help the situation.（分数：1.50）A.neednt tellB.mustnt tellC.mustnt have toldD.neednt have told解析：解析 虚拟式的用法。neednt have done sth. 表示做了本来不必要做的事情，D正符合题意。A不是虚拟用法；B意为“不能告诉”，不符合上下文意思；很少使用mustnt
36、have done这种表达，C错。10.If powerful measures _, this area would have been badly polluted.（分数：1.50）A.arent takenB.havent been takenC.werent takenD.hadnt been taken解析：解析 考查虚拟语气。由主句的时态would have been可看出，这是对过去情况的描述，且与过去事实相反，实际上过去已经采取了措施，故此处用过去完成时表示对过去的虚拟，答案为D。11.He _ furiously at me when I contradicted him.
37、（分数：1.50）A.ogledB.gapedC.glaredD.peered解析：解析 根据句中的furiously以及I contradicted him判断，He应该是“生气的”，故选C“怒视”。12.The Internet, cell phones, palmtop computers and other digital technology allows one to quickly gain _ to a variety of information.（分数：1.50）A.rightB.privilegeC.accessD.entrance解析：解析 gain access to
38、是固定用法，表示“使用，接近，可以利用”，其余三项均无此用法。13.He is quite sure that its _ impossible for him to fulfill the task within two days.（分数：1.50）A.absolutelyB.exclusivelyC.fullyD.roughly解析：解析 absolutely impossible指“绝对不可能”，是常见的搭配。14.The local police are authorized to _ anyones movements as they think fit.（分数：1.50）A.hal
39、tB.pauseC.repelD.keep解析：15.With favorable weather conditions, it was a(n) _ moment to set sail.（分数：1.50）A.auspiciousB.suspiciousC.graciousD.ferocious解析：16.Smoking is _ in public buildings.（分数：1.50）A.avoidedB.prohibitedC.rejectedD.repelled解析：17.His expenditure on holidays and luxuries is rather high
40、in _ to his income.（分数：1.50）A.proportionB.comparisonC.associationD.calculation解析：18.Sometimes we forget about our _ and try to blend in with our surroundings.（分数：1.50）A.temperB.characterC.individualityD.personality解析：19.An army spokesman claims the militants are _ the run.（分数：1.50）A.inB.offC.onD.aft
41、er解析：解析 on the run是固定搭配，表示“在逃，被通缉”。20.The Canton Tower is one of the most _ landmarks in Guangzhou.（分数：1.50）A.dominantB.prominentC.leadingD.foremost解析：21.Which of the following sentences is INCORRECT?（分数：1.50）A.They have enough time to finish the paper.B.Dad says the meat is not enough cooked.C.You
42、are not old enough to buy alcohol.D.She plays well enough for a beginner.解析：解析 考查enough的用法。enough修饰名词时，位于名词之前；当它修饰形容词、副词或动词时，一般位于它们的后面。B中enough修饰动词cooked，应位于其后，因此答案为B。22.Smoking is so harmful to health that it kills _ each year than automobile accidents.（分数：1.50）A.more seven times peopleB.seven time
43、s more peopleC.more people seven timesD.people seven times more解析：解析 本题考查倍数的其中一种表达法，即“倍数+more.than.”，正确表达为B。常见的倍数表达结构还有：A is+倍数+the size(length, width, height, etc.)+of B；A is+倍数+as+形容词+as B；A is+倍数+形容词比较级+than B。23.Mr. White, together with all his colleagues, _ for Europe this morning.（分数：1.50）A.are leavingB.leaveC.is leavingD.are to leave解析：解析 考查主谓一致。当主语后带有诸如as well as, together with, rather than, as much as, no less than等介词词组时，谓语视中心词，即主语的单复数情况而定，因此只有C符合题意。另外leave作为表示位置移动的动词，其进行时态可以表示将来动作。24.You _ call your fathers name directly. Its impolite in China.（分数：1.50）A.oughtntB.mustntC.needntD.wou
