16、时间：90分钟)一、GRAMMAR & VOCABULARY(总题数：33，分数：66.00)1.PART IV GRAMMAR & VOCABULARY (15 MIN)Directions: There are thirty sentences in this section. Beneath each sentence there are four words or phrases marked A, B, C and D. Choose one word or phrase that best completes the sentence.（分数：2.00）_解析：2.Mr. Whit
17、e works with a chemicals import & export company, but he _ for this industrial fair, since he is on leave.（分数：2.00）A.has workedB.worksC.has been workingD.is working解析：解析：从句意来看，怀特先生并不是工业交易会的长期雇员，所以不能用一般现在时；此外他正在休假期间，所以才有空做其他工作，所以包含过去含义的现在完成时和现在完成进行时都不合适；现在进行时与“在休假期间”相吻合，所以D为正确选项。3.Professor Johnson i
18、s said _ some significant advance in his research in the past year.（分数：2.00）A.having madeB.makingC.to have madeD.to make解析：解析：is said后跟不定式，不能跟动词-ing形式，排除A和B。从句中的时间状语in the pastyear可以看出动作已经发生并完成。C项to have made是不定式的完成式，表示动作发生在谓语动词之前，而D项to make表示动作没有发生，故C项正确。4.I _ the party much more if there hadnt bee
19、n quite such a crowd of people there.（分数：2.00）A.would enjoyB.will have enjoyedC.would have enjoyedD.will be enjoying解析：解析：本句含有if引导的条件句，从句中使用了hadnt been，是对过去情况的假设，因此主句的结构应为would have done，故答案为C。5.If you explained the situation to your solicitor, he _ able to advise you much better than I can.（分数：2.00
20、）A.would beB.will have beenC.wasD.were解析：解析：本题条件状语从句中的谓语动词用了过去式explained，说明其内容与现在或将来的情况相反，所以主句的谓语动词应该用“would+动词原形”，答案为A。6.If you _ in such a hurry you _ sugar into the sauce instead of salt.（分数：2.00）A.were not, would not putB.were, would putC.had been, would have putD.had not been, would not have pu
21、t解析：解析：题干中把糖放到酱汁里这个动作已经发生，因此本句是对过去情况的假设。if条件状语从句应使用had done，主句使用wouldshouldcould have done。选项C和D在语法上都对，不过C用了肯定，表示“如果你匆忙，你会把糖当成盐放到酱汁里”，意思上不合逻辑，故D项正确。7._ their help, we would not have succeeded.（分数：2.00）A.Hadnt been forB.Had it not been forC.It hadnt been forD.Had not it been for解析：解析：本句是省略了if的虚拟条件句，原
22、句的正常语序为：If it had not been for their help省略if时，只提前助动词，否定词not不用提前，即Had it not been for.故答案为B。8.She asked that she _ allowed to see her son in police custody.（分数：2.00）A.would beB.could beC.beD.was解析：解析：ask作“请求，要求”讲时，其后的宾语从句要用虚拟语气，从句谓语动词使用“(should+)动词原形”。类似用法的动词还有demand，suggest，order，require，desire，sur
23、prise等等。9.It is necessary that he _ the assignment without delay.（分数：2.00）A.hand inB.hands inC.must hand inD.has to hand in解析：解析：在“It iswas+形容词+that从句”中，that引导的主语从句谓语动词常用should+动词原形。用于该句型的形容词有necessary，good，important，right，wrong，better，natural，proper，funny，strange，surprising等。10.It is absolutely ess
24、ential that William_his study in spite of some learning difficulties.（分数：2.00）A.will continueB.continuedC.continueD.continues解析：解析：It is essential that句型中，that引导的从句用虚拟语气，谓语动词用“should+动词原形”，should可以省略。故C为正确选项。类似的形容词还有：important，necessary，imperative，advisable，desirable等。11.If only I _ play the guitar
25、as well as you!（分数：2.00）A.wouldB.couldC.shouldD.might解析：解析：If only从语义和用法上都相当于I wish，后面的谓语动词用一般过去时表示目前的愿望，用过去完成时表示过去的愿望，用wouldcould do表示对将来期望。选项中首先可排除C和D。而A项would侧重指人的意愿，B项could是指人的能力。句子的意思主要是指弹钢琴的能力，所以应该选择B。12._ you _ further problems with your printer, contact your dealer for advice.（分数：2.00）A.If,
26、hadB.Have, hadC.Should, haveD.In case, had解析：解析：本句的主句使用了祈使句，而非虚拟，因此从句应理解成对真实情形的一种假设。A项使用一般过去时，是对现在或将来情况的虚拟，而if真实条件句应使用一般现在时表示将来，所以A不正确，应该使用if you have；B和C都省略了if，B项have had是对过去情况的虚拟，不正确：C项中的should用在假设句中，加强语气，should have是对将来情况的假设，故C为正确答案：D项Incase“万一，以防”引导的从句使用一般现在时或should+动词原形，不能用had。13.It was recomme
27、nded that passengers _ smoke during the flight.（分数：2.00）A.notB.need notC.could notD.would not解析：解析：It is recommended that表明that从句需要使用虚拟语气，其形式为“should+动词原形”，其中should可以省略，故答案为A。14.If you have really been studying English for so long, its about time you _ able to write letters in English.（分数：2.00）A.sho
28、uld beB.wereC.must beD.are解析：解析：it is(about)time(that)是一个虚拟语气句型，所跟从句的谓语动词用一般过去式，故B项were为答案。15.I was to have made a speech if_.（分数：2.00）A.I was not called awayB.nobody would have called me awayC.I had not been called awayD.nobody called me away解析：解析：waswere to have done sth表示“本来要做成的”，表示与过去事实相反，从句谓语动词
29、应使用had done，所以应选C。16.Its getting late, Id rather you _ now.（分数：2.00）A.leftB.leaveC.are leavingD.will leave解析：解析：would rather“宁愿”后接从句时，从句动词用一般过去式表虚拟，故答案为A。注意区分would rather其他两个惯用句式：would rather do sth“宁愿做某事”；would rather dothando“宁愿做而不愿做”。17.Its high time we _ cutting down the rainforests.（分数：2.00）A.s
30、toppedB.had to stopC.shall stopD.stop解析：解析：It is(high)time(that)后面的从句谓语动词要用过去式或“should+动词原形”，且should不可省略，故A项stopped为答案。B项had to stop表示“一定要停止”，C项是将来时，D项动词原形，都不符合条件。18.If only the patient _ a different treatment instead of using the antibiotics, he might still be alive now.（分数：2.00）A.had receivedB.rec
31、eivedC.should receiveD.were receiving解析：解析：if only常常用来表达强烈的愿望或遗憾，由于“接受不同的治疗”与过去事实相反，所以用过去完成时。故A项had received正确。19.She seldom goes to the theatre, _?（分数：2.00）A.doesnt sheB.does sheC.would sheD.wouldnt she解析：解析：若陈述部分含有seldom，hardly，never，rarely，few，nothing，nowhere等否定词或半否定词其反意疑问句部分要用肯定式。同时句中时态是一般现在时，故选
32、B。20.She would have been more agreeable if she had changed a little bit, _?（分数：2.00）A.hadnt sheB.hasnt sheC.wouldnt sheD.didnt she解析：解析：如果陈述部分是主从复合句，一般情况下，疑问部分与主句一致。本题主句部分的助动词是would。故疑问部分用wouldnt she，C项正确。21.I suppose that he is just joking, _?（分数：2.00）A.dont IB.isnt heC.isnt itD.is it解析：解析：当陈述部分的主句
33、是I suppose，I think，I believe等结构时，反意疑问句部分一般与that分句中的主谓保持对应关系。本句的从句是he is，所以正确答案为B。22.Do help yourself to some fruit, _ you?（分数：2.00）A.cantB.dontC.wouldntD.wont解析：解析：祈使句的附加疑问句。在英语中，当前面的句子是祈使句时，其附加疑问句用wont you，will you或would you。因此D项正确。23.When you have finished with that book, dont forget to put it bac
34、k on my desk, _?（分数：2.00）A.do youB.dont youC.will youD.wont you解析：解析：主句dont forget是祈使句的否定形式，否定祈使句的反意疑问结构总是用will you，故选C。24.A hibernating animal needs hardly any food all through the winter, _?（分数：2.00）A.need itB.neednt itC.does itD.doesnt it解析：解析：needs在本句用作实义动词，且陈述部分含有否定副词hardly，故疑问部分用does it，答案为C。2
35、5._ both sides accept the agreement_ a lasting peace be established in this region.（分数：2.00）A.Only if, willB.If only, wouldC.Should, willD.Unless, would解析：解析：only引导状语从句置于句首时，主句需倒装，选项A符合题意。而If only只用于感叹句，常见于虚拟语气。表示“要是就好了”，不用于条件句中，因此在这句话里并不适合。should置于句首，相当于省略if的条件句，表示口气的不确定性，但主句部分并不倒装，因此C不合适；同样，D也不应有倒
36、装现象。26.Only take such clothes _ really necessary.（分数：2.00）A.as wereB.as they areC.as they wereD.as are解析：解析：本句是祈使句，开头的only修饰谓语，故不用倒装。suchas结构中的as，可充当准关系代词，替代前面出现的先行词clothes；本句的动作并未发生，所以不用一般过去时而用一般现在时。故答案为D项as are.27.So badly _ in the car accident that he had to stay in hospital for a few months.（分数：
37、2.00）A.did he injureB.injured himC.was he injuredD.he was injured解析：解析：副词so放句首，句子主谓要倒装。so badly在句中作状语，放句首表示强调。原句是“Hewas injured so badly in the car accident that”，倒装时只要把系动词或助动词移到主语前面就可以了。因此答案选C。28._ he needed money for a new car, he decided not to borrow it from the bank.（分数：2.00）A.Much asB.Much alt
38、houghC.As muchD.Though much解析：解析：考查让步状语从句的倒装结构。as和though引导的让步状语从句通常将表语、状语或谓语动词提前，使用倒装结构。又如A符合题意。29.The central provinces have floods in some years, and _.（分数：2.00）A.drought in othersB.droughts are othersC.while other droughtsD.others in drought解析：解析：此题中and是并列连词，连接两个并列成分，要求两个并列部分语法对等，即与floods insome
39、years结构保持一致，故正确答案为A。30.This may have preserved the elephant from being wiped out as well as other animals _ in Africa.（分数：2.00）A.huntedB.huntingC.that huntedD.are hunted解析：解析：as well as连接并列分句，要求前后结构一致，形成比较，该旬的完整形式应为：as wellas other animals from being hunted为了避免重复，本题省略了与前面的重复部分from being因此A为正确答案。31.T
40、he following are all correct responses to Who told the news to the teacher? EXCEPT（分数：2.00）A.Jim did this.B.Jim did so.C.Jim did that.D.Jim did.解析：解析：最常见的回答是D，也可以用so和that指代前文提到的动作“told the news to theteacher”，故B和C也可以用作回答。this多用指下文的内容，故不能用于题中的场合。选A。32.Acute hearing helps most animals sense the approa
41、ch of thunderstorms long before people（分数：2.00）A.doB.hearC.do themD.hearing it解析：解析：本题由before引导的从句中，people的谓语与主句中宾语animals的补语动词(sense)相同，因此为避免重复由助动词do替代。33.A: Mother, you promised to take me out. B: Well, _（分数：2.00）A.so do I.B.so did I.C.so I do!D.so I did!解析：解析：考查动词性替代。A抱怨妈妈说话不算数；B用了一个语气词well表明她承认自己曾经许诺过这事。“so+主语+助动词”表示说话人认同对方的看法，该结构中的主语指的就是前一句话中的主语，根据前一句的promised可知助动词应使用过去式did，故答案为D。“so+助动词+主语”结构表示“也是这样”，该结构中的主语与前一句的主语指代不同的对象，故不选A。
