13、ARY(总题数：24，分数：48.00)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.Its high time we_cutting down the r

14、ainforests.（分数：2.00）A.stoppedB.had to stopC.shall stopD.stop解析：解析：if only引导的虚拟条件句，是对过去事实的虚拟，所以用过去完成时态。A为答案。3.My boss ordered that the legal documents_to him before lunch.（分数：2.00）A.be sentB.were sentC.were to be sentD.must be sent解析：解析：虚拟语气题。结构It is high time(that)后面的从句部分要使用虚拟语气，因此A正确。4.Ii is absolu

15、tely essential that William _ his study in spite of some learning difficulties.（分数：2.00）A.will continueB.continuedC.continueD.continues解析：解析：因为ordered后面接宾语从句，从句中谓语动词必须使用虚拟语气，即“should+动词原形”；同时，因为文件是被送，所以这里需要用被动语态，因此A为答案。5.It is not uncommon for there_ problems of communication between the old and the

16、 young.（分数：2.00）A.beingB.would beC.beD.to be解析：解析：essential表示“必须的”，其后所接从句中谓语用“should+动词原形”表示虚拟，其中should可省略。故C为答案。6.The Minister of Finance is believed_of imposing new taxes to raise extra revenue.（分数：2.00）A.that he is thinkingB.to be thinkingC.that he is to thinkD.to think解析：解析：此题考查there be结构的不定式用法，

17、there be句型在介词for之后使用时，用there to be结构，本句it是形式主语，真正的主语是“for there to bethe young”，D为答案。当there be用于介词of之后时，用there being这一结构。7.Linda was_ the experiment a month ago, but she changed her mind at the last minute.（分数：2.00）A.to startB.to have startedC.to be startingD.to have been starting解析：解析：不定式作主语补足语。英语中

18、通常对“it is believed that”做如下转换：It isbelieved that he is=He is believed to be。故B为答案。8._should not become a serious disadvantage in life and work.（分数：2.00）A.To be not tallB.Not being tallC.Being not tallD.Not to be tall解析：解析：“werewas+to+动词原形”表示过去将来时间的安排，如果这个安排后来被取消了，没有实现，则用过去将来完成式was/were to have done，

19、所以选B。9.What a nice day! How about the three of us_a walk in the park nearby?（分数：2.00）A.to takeB.takeC.takingD.to be taking解析：解析：本句缺主语，动名词作主语时，通常用于表示一件已知的事情或者经验。不定式短语通常表示一件未完成的事或目的。本句中“长得不高“是一件已知的事情，所以选择动名词短语作主语，表示否定意义，not要放在名词前面。故B正确。10.Children who stay away from school do_for different reasons.（分数

20、：2.00）A.themB./C.itD.theirs解析：解析：how about后常接名词或者动名词，表示征求意见。因此C为答案。11.We consider_he should have left without telling anyone beforehand.（分数：2.00）A.strange whyB.it strange whatC.it strange thatD.ihat strange解析：解析：it可指代抽象的行为，这里指代stay away from school。而A、D只可指代具体的事物，均排除；do后面必须接宾语，B显然不对。因此C为答案。12.Little_

21、about her own safety, though she herself was in great danger.（分数：2.00）A.she caredB.she may careC.may she careD.did she care解析：解析：此句中it作形式宾语接在谓语动词之后，用that引导从句be should have leftwithout telling anyone beforehand作真正的宾语接在其后，构成“动词+it+补语+that宾语从句”结构。因此C为答案。13._both sides accept the agreement _ a lasting p

22、eace be established in this region.（分数：2.00）A.Only if, willB.If only, wouldC.Should, willD.Unless, would解析：解析：表示否定意义的词位于句首时，其后用倒装结构。实义动词的倒装要用助动词帮助其构成倒装；此题中时态为过去时，所以用助动词did构成倒装。因此D为答案。14.There are only ten apples left in the baskets, _the spoilt ones.（分数：2.00）A.not countingB.not to countC.dont countD

23、.having not counted解析：解析：根据句意，这里是条件状语从句的倒装，“only+状语”位于句首时，句子用倒装结构。句子的正常语序是：A lasting peace will be established in this region only if both sidesaccept the agreement。注意区分，if only意为“要是就好了”。因此A为答案。15._at in his way, the situation doesnt seem so desperate.（分数：2.00）A.LookingB.LookedC.Being lookedD.To loo

24、k解析：解析：用现在分词形式表示与主句动作紧密相联，此处表主动。count“把计算在内，包括”，counting相当于including。因此A为答案。16.If not _ with the respect he feels due to him, Jack gets very ill-tempered and grumbles all the time.（分数：2.00）A.being treatedB.treatedC.be treatedD.having been treated解析：解析：此句中，主语为the situation，要填内容与the situation之间是被动关系，即

25、thesituation被看，所以用过去分词来表达此意。选项C表达正在被看，不符合题意。A表主动之意，D表将来之意，均不符合题意。因此B为答案。17.The man preparing the documents is the firms lawyer has all the following possible meaning EXCEPT_.（分数：2.00）A.the man who has prepared the documentsB.the man who has been preparing the documentsC.the man who is preparing the

26、documentsD.the man who will prepare the documents解析：解析：空格处要填入的内容与其逻辑主语Jack(即主句主语)之间为被动关系，当条件状语从句的主语和主句主语一致，并且从句谓语含有be动词时，可以将从句主语和be一并省略，即将he is省略，状语从句补充完整为：If he is not treated with。B为答案。18.Agriculture is the countrys chief source of wealth, wheat_by far the biggest cereal crop.（分数：2.00）A.isB.beenC.

27、beD.being解析：解析：现在分词作定语一般表示“主动”或者“进行”，A、B、C三个选项表示的时间都是“现在”，符合现在分词定语的含义。而D则表示的是“将来”，一般用不定式结构作后置定语。D为答案。19.Time_, the celebration will be held as scheduled.（分数：2.00）A.permitB.permittingC.permittedD.permits解析：解析：考查带主语的现在分词构成独立主格结构，表伴随。分词与其逻辑主语之间为主动关系，所以应用现在分词。D为答案。20.Whats the chance of_a general electi

28、on this year?（分数：2.00）A.there beingB.there to beC.there beD.there going to be解析：解析：考查独立主格结构。分词与其主语time之间为主动关系，所以应用现在分词。独立主格Time permitting=If time permits，在句中表条件。B为答案。21.James has just arrived, but I didnt know he_until yesterday.（分数：2.00）A.will comeB.was comingC.had been comingD.came解析：解析：介词of后应接动名

29、词being，而动名词的逻辑主语是a general election，there be结构是其谓语，因此这里用there be结构的动名词形式there being。故A为答案。22._conscious of my moral obligations as a citizen.（分数：2.00）A.I was and always will beB.I have to be and always will beC.I had been and always will beD.I have been and always will be解析：解析：本句是在过去时间里的将来动作，应用过去将来时

30、，又由于come，go，leave等一类表示位移的动词可以用进行时表示将来，was coming表达的就是过去将来时。因此B正确。23.For some time now, world leaders _ out the necessity for agreement on arms reduction.（分数：2.00）A.had been pointingB.have been pointingC.were pointingD.pointed解析：解析：本句为一般性陈述，没必要用过去时态，排除A、C；B中have to表示不得不做某事，而will表示主观愿意去做某事，两者语义矛盾；D中have been表示从过去一直持续到现在，且will be表示从现在开始将继续持续到将来，两者在时态上连贯，符合题意。D为答案。24.The student said there were a few points in the essay he_impossible to comprehend.（分数：2.00）A.had foundB.findsC.has foundD.would find解析：解析：For some time now表示动作从过去持续到现在，又包括现在阶段正在进行，故用现在完成进行时，强调从过去到现在各国领导人都知道削减武器的必要性。B为答案。
