No, you _.“（分数：1.00）A.won“tB.needn“t C.can“tD.d
22、on“t解析：解析 译文：“我现在必须做这件事吗?”“不，你不必。”must 意为“必须、必要”。回答must引导的问句时，如果是否定的回答，不能用 mustn“t，而要用 needn“t或 don“t have to。答案为B。2.She was absent from class for a week. She _ sick.（分数：1.00）A.may beB.could be C.might beD.must have been解析：解析 译文：她已经旷课一周了。她可能生病了。在肯定句中，may 表示现实可能性，can 表示理论可能性，might 是 may的过去式，could 是 c
23、an的过去式，而 must+have+been表示对过去发生的事情的肯定推测。而本句只是通过没来上课推断其原因可能是她生病了。答案为 B。3.You _ to have done silly things.（分数：1.00）A.had oughtB.hadn“t oughtC.didn“t oughtD.ought not 解析：解析 译文：你不应该做这么愚蠢的事情。根据题意知本题要用否定，A 错；ought to 意为“应该”，是情态动词，它不受人称和时态的限制，其否定直接在 ought后加 not。答案为 D。4.I haven“t been able to answer his lett
24、er. Perhaps I _ next week.（分数：1.00）A.wouldB.mayC.am able toD.will be able to 解析：解析 译文：我还不能给他回信呢。或许我下周能给他回。从题中的时间状语 next week可知本题要用一般将来时，而此处要意为“能够”，可用 be able to。答案为 D。5._aloud to me while I do the ironing? With pleasure. What book would you like?（分数：1.00）A.Will you read B.Do you readC.Are you going
25、to readD.Did you read解析：解析 译文：当我熨衣服的时候你愿意大声读吗?从回答 with pleasure可知四个选项中能表示意愿的只有 will；D 是 B的过去式，不仅时态不对，而且 B和 D只是对 read aloud的提问，不带感情色彩；C意为打算，计划，不合题意。答案为 A。6.The swimmer was very tired but he _ reach the shore before he collapsed.（分数：1.00）A.couldB.was able to C.mightD.may解析：解析 译文：虽然游泳者非常累，但在筋疲力尽之前，他还是能
26、够游到岸边的。can 与 be able to均可表某人做某事的能力，常可互换。但 can的时态只有现在时(can)和过去时(could)；be able to根据需要可以用各种时态，还可与情态动词连用。而且 can指有能力，但实际上不一定做得到，而 be able to指不仅有能力，且实际上做到了。could 是 can的过去式；might 是 may的过去式，两者都表示可能，且可能性比 can小。根据句意游泳者实际上做到了。答案为 B。7.If it sounds too good to be true, it _ just a Pyramid Scheme.（分数：1.00）A.migh
27、t be B.could beC.will beD.can be解析：解析 译文：如果这件事情听起来太完美了而不真实，它可能就是非法传销。本题用“情态动词+动词原型”表示对现在的事情的推测。can，could 和 might都可用在条件句中，表示假想的情况，其可能性依次减弱，若无客观事实根据，纯凭主观臆断，则猜测语气弱。本题没有事实依据，要用推测性最弱的。答案为 A。8.Mr. Brown was concerned that his unpopular political position _ a disastrous effect on his career.（分数：1.00）A.coul
28、d beB.might have C.have beenD.shall be解析：解析 译文：布朗先生担心他不得人心的政治地位可能会对他的事业造成不良影响。have an effect on sth. 意为“对产生影响”，是固定搭配。根据题意知本题是表示推测，用情态动词+动词原形即可。答案为 B。9._ you be happy!（分数：1.00）A.May B.CanC.MustD.Would解析：解析 译文：祝你幸福。此处 may表示希望，祝愿，意为“祝，但愿”；其他三项没有这种用法。答案为 A。10.I don“t believe him, he _ be serious.（分数：1.0
29、0）A.needn“tB.can“t C.shouldn“tD.mustn“t解析：解析 译文：我不相信他，他不可能是认真的。A 表示“没必要”；B 为否定的推测，意为“不可能”；C 为“不应该”，指可以这么做但是不应该这么做；D 为“禁止做”，must 一般只表肯定的推测。根据题意知本题是否定的推测。答案为 B。11.As it turned out to be a small house party, we _ so formally.（分数：1.00）A.need not have dressed up B.must not have dressed upC.did not need t
30、o dress upD.must not dress up解析：解析 译文：事实证明那只不过是一个小型的家庭聚会罢了，所以我们没有必要穿得那么正式。need既可用作实义动词也可作情态动词，作实义动词时用 need to do sth.；作情态动词时，need not do sth. 意为“没有必要做”；must not do sth. 意为“禁止做”。根据题意知本题要用need，而且 dress up发生在 turned out之前，要用“情态动词+have done”表示与过去事实相反，意为“本应该”。答案为 A。12.If we hadn“t got everything ready by
31、 now, we _ a terrible time tomorrow.（分数：1.00）A.would have B.had hadC.would have beenD.would have had解析：解析 译文：如果我们现在还没有准备好一切的话，我们明天将会很麻烦的。从句子结构看，if条件句中用的是过去完成时，主句很容易错选 D，事实上本题不是对过去的虚拟，因为题中有具体的时间状语 tomorrow，主句要用将来时。答案为 A。13.You are welcome. This is what I _ do.（分数：1.00）A.should be able toB.had betterC
32、.ought to D.might解析：解析 译文：不用谢，这是我应该做的。should be able to do 意为“应该能够”，表示一种能力；had better do 意为“最好”，表示一种建议；ought to do 意为“应该”；might 意为“可能”。答案为 C。14.If you had others do your homework, you _ them eat your lunch.（分数：1.00）A.had better to haveB.might as well haveC.should have to haveD.ought to have 解析：解析 “h
33、ad better+动词原形”意为“最好”；might as well 意为“不妨，也应该”；should have done意为“本该做”；ought to do 意为“应该做”。D 项的语气更坚定。原句意为：如果你让别人帮你做作业，那你也应该让他们吃你的午饭。答案为 D。15.You _ pass the exams before you could enter the college.（分数：1.00）A.has toB.mustC.had to D.need解析：解析 译文：你得先通过考试才能上大学。have to 意为“不得不”，指的是一种客观需要，有各种时态和人称的变化；must
34、意为“必须，必要”，指的是说话人的主观看法；need 意为“需要”，指的是一种必要性和一种客观的需要。从句中的 could可知主句要用过去式，即 had to。答案为 C。16.Mr. Jones, _ you tell me what has happened?（分数：1.00）A.mayB.mustC.mightD.could 解析：解析 译文：琼斯先生，你可以告诉我究竟发生了什么吗?句型“could you do sth.?”表示提出请求，是固定用法。答案为 D。17.The onset of spring in Britain _ come quietly this year due
35、to dwindling numbers of cuckoo.（分数：1.00）A.mightB.wouldC.may D.can解析：解析 译文：由于布谷鸟在逐渐减少，英国的春天今年可能会静静的到来。根据题意知本题是对将来的推测，B 为过去将来时，时态不符；A、C、D 都表示推测，D 用于否定的推测，表示“不可能”，与本题不符；A 指的是没有事实依据的推测，因为本题后面讲了布谷乌减少，有一定的事实依据，用 C更符合题意。答案为 C。18.“Did they blame him for his mistakes?“ “Yes, but they _ so.“（分数：1.00）A.would r
36、ather not doB.shouldn“t doC.shouldn“t have done D.had better not do解析：解析 译文：“他们因为他犯的错误责备他了吗?”“是的，但是他们本不该这么做”。would rather not do意为“宁愿不做”；shouldn“t do 意为“不应该做”；shouldn“t have done 意为“本不该做”；had better not do 意为“最好不要做”。根据句意知实际上他们已经批评他了，要用对过去的虚拟。答案为 C。19.The girl _ prefer to give him the cash and call i
37、t square.（分数：1.00）A.couldB.shouldC.oughtD.might 解析：解析 译文：这个女孩也许愿意把钱给他，从而两不相欠。should 意为“应该”，ought 后接动词要用 ought to。根据题意本题要用表推测的情态动词，could 和 might都表推测，但是 could的可能性比 might大，本题没有事实依据，要用可能性较小的 might。答案为 D。20.Since she is angry, we _.（分数：1.00）A.had better leaving her aloneB.should leave her aloneC.must lea
38、ve her aloneD.might as well leave her alone 解析：解析 译文：既然她生气了，我们让她单独待会儿也好。had better 意为“最好”，表建议，其后接动词原形，A 错；B 和 C语气太强，合有强制性的，不合题意。might as well 意为是合乎情理的，表示一种提议，符合题意。答案为 D。21.You _ her in her office, because she“s been on business just for a week.（分数：1.00）A.needn“t have seenB.might have seenC.must have
39、 seenD.can“t have seen 解析：解析 译文：你不可能在办公室见到过她，因为她已经出差一周了。needn“t have done 表本来不需要做某事而做了；might have done 表可能做过某事；must have done 表对过去事情的肯定推测，译成“一定做过某事”；can“t have done 表对过去事情的否定推测，译成“不可能做过某事”。根据题意知本题是对过去的否定推测，要用 D。答案为 D。22.He promised me a letter; he ought to _ it days ago.（分数：1.00）A.be writtenB.have w
40、ritten C.be writingD.write解析：解析 译文：他承诺过给我写信；他应该几天前就已经写好了。从 days ago知写信是过去的事情，此处为情态动词 ought to+have done表示对过去的事情进行推测，因此要用 B。he 和 write a letter之间是逻辑上的主谓关系，A 错；从 days ago知此处不能用现在进行时，C 错；D 为对现在和将来发生的事情的推测。答案为 B。23.We didn“t know his telephone number, otherwise we _ him.（分数：1.00）A.would telephoneB.would
41、 have telephoned C.had telephonedD.must have telephoned解析：解析 译文：我们不知道他的电话号码，不然我们就给他打电话了。根据题意知，本题是对过去的虚拟，讲述的是与过去事实相反的情况，要用 would/could/might+have done表示“本该做而事实上未做”。答案为 B。24.No one _ the truth to her.（分数：1.00）A.dares tellB.dare tellsC.dares tellsD.dare tell 解析：解析 dare 作情态动词时，主要用于疑问句和否定句中，其后直接接动词原形，一般不
42、用在肯定句中；其否定形式是直接在后面加 not。答案为 D。25.Mary“s score on the test is the highest in her class; she _ have studied very hard.（分数：1.00）A.mayB.shouldC.must D.ought to解析：解析 前一个句子意为“在玛丽所在的班级，她的测验成绩是最高的”，根据语境可知后一个句子应表示肯定的推测，即她(最近)肯定学习非常刻苦。should 和 ought to一般表示“应该”，不合题意。may猜测的程度较低。must 表示肯定的猜测，与完成时态连用，是对过去发生的事情的肯定
43、推测。答案为C。26.Mr. Smith isn“t here yet. I think he _ about the meeting.（分数：1.00）A.should have forgotB.ought to forgetC.must have forgotten D.may not forget解析：解析 译文：史密斯还没有来这。我认为他肯定忘了开会。must have done 表示对过去发生的事情进行肯定推测，属于虚拟语气的范畴。此题前一句话暗示了后一句话应用肯定推测的语气。答案为 C。27.I _ everything by the time you get back next
44、week.（分数：1.00）A.shall finishB.have finishedC.will be finishingD.shall have finished 解析：解析 译文：你下周回来的时候我将会做完所有的事情。时间状语 by the time.一般与完成时连用，因此可排除 A、C 项。next week 说明为将来时，shall 用在第一人称表示将来。答案为 D。28.I said a high school girl who has a record of dependability _ to date.（分数：1.00）A.should be permitted B.shal
45、l permitC.would be permittedD.will permit解析：解析 译文：我说过一个有着信用记录的高中女生应该得到许可证。a high school girl 与permit之间是逻辑上的动宾关系，要用被动语态。而且根据题意知本题表示“应该”之意，要用should。答案为 A。29.Mary _ have been invited to the party, but she wasn“t.（分数：1.00）A.mustB.should C.canD.would解析：解析 译文：玛丽本应该被邀请去参加聚会，可她并没有被邀请。should have done 表示“本应该但事实上没有”，属于虚拟语气的范畴。答案为 B。三、PART TWO(总题数：0，分数：0.00)四、改错题(总题数：6，分数：6.00)30.You could listen to the doctor“s advice. （分数：1.00）解析：couldshould解析 译文：你应该听医生的建议。could 可表具备某种能力，意为“能”；should可表示出主语的惊讶、不满、责备等情绪，意为“应该”。根据题意知本题带有轻微的责备语气，要用 should。答案为 couldshould。31.The truth of course
