23、mid专业英语四级-249答案解析 (总分：100.00，做题时间：90分钟)一、LANGUAGE USAGE(总题数：40，分数：100.00)1.Five minutes earlier, _ we could have caught the last train.（分数：2.50）A.andB.butC.orD.so解析：解析 该题是语法结构题，考查并列句结构所表示的条件概念和虚拟语气。条件概念主要用条件状语从句表示，但是还有其他许多方法可以用来表示条件，“名词结构/祈使句+and+分句”就是其中一种，如：One more step and you will fall over the
24、cliffs. 你要再往前一步，就会掉下悬崖。又如：Give him an inch and he will take a mile.如果你让他一英寸，他会进一英里(得寸进尺)。因此，选项A为最佳答案。2.So little _ about physics that the lecture was completely beyond her.（分数：2.50）A.she knowsB.does she knowC.she knewD.did she know解析：解析 该题是语法结构题，考查倒装结构的意义和用法。 根据倒装结构的语法规则，带否定意义的副词或词组用于句首作状语时，该句子要用倒装。
25、常见的带否定意义的词和词组有：never、seldom、little、scarcely、not until、by no means、in no time、not only.but also.等，如：Never shall I forget the lesson. 我决不会忘记这个教训。又如：Not only was Churchill a statesman, but also he was a poet.丘吉尔不仅是一位政治家，还是一位诗人。根据此语法规则，选项A和选项C可以首先排除掉。选项B的时态与that后面的从句不一致，也不能选。因此，选项D为最佳答案。3.Eliza must hav
26、e missed the train; otherwise she _.（分数：2.50）A.should arriveB.has arrivedC.would have arrivedD.arrived解析：解析 该题是语法结构题，考查虚拟语气在非真实的条件句中的用法。 此题的非真实条件由副词otherwise表示，意思为“要不然”，表示与前面提到的事实相反，相当于“if she had not missed the train”。主句谓语动词arrive应该用过去将来完成时。其他几个选项不符合题意。因此，选项C为最佳答案。4.If you ask me, I dont think _ to
27、 leave the task to him. Maggie would be a better choice.（分数：2.50）A.you are wise ofB.it wise of youC.it was wise for youD.it is wise of you解析：解析 该题是语法结构题，考查对句子结构的认识和动词不定式逻辑主语的表示法。 在该句子中，it是形式宾语，带逻辑主语的动词不定式是句子真正的宾语，wise作句子的宾语补足语。根据相关的语法规则，在通常情况下，动词不定式逻辑主语由介词for引出，但在该句子中，由于宾语补足语是表示人物性格、特点等的形容词，故动词不定式的逻
28、辑主语要由介词of引出。类似的形容词还有brave、careful、clever、considerate、good、foolish、kind、honest、polite、silly、rude等，如：I think it (is) wrong of him not to accept our invitation. 我认为他不接受我们的邀请是错误的。选项C中的介词for也是错误的。选项D的介词是正确的，但时态与题干时态不一致，否则该选项也是正确的，构成think的宾语从句。因此，选项B为最佳答案。5.His salary as a bus driver is much higher _.（分数：
29、2.50）A.in comparison with a teachersB.than that of a teacherC.than a teacherD.than of a teachers解析：解析 该题是语法结构题，考查比较结构的意义和用法。 在使用比较等级时要注意比较的一致性和排他性，否则，该比较没有任何意义。比如：Her English is as fluent as her teacher. “她的英语”不能和“她的老师”进行比较，该句违背了一致性原则，应该改写为：Her English is as fluent as her teachers. 再看下面一句：Tom is mor
30、e diligent than any student in his class. “任何学生”也包括Tom本人，该句违背了排他性原则，应该改为：Tom is more diligent than any other student in his class.故选项C可以首先排除。选项D意义不完整，在than和of之间遗漏了that，也可以迅速排除。选项A中的“in comparison with his teachers”有“与相比”的意义，也有“老师的工资”之义，但不能与题干中的higher搭配higher要求搭配一个带than的结构。因此，选项B为最佳答案。6._ London of D
31、ickens time comes to _ life in his books.（分数：2.50）A.The; /B./; /C./; theD.The; the解析：解析 该题是语法结构题，考查冠词的用法。 专有名词前一般不需要使用定冠词，但在该句中，London后面有介词短语作定语，特指某一时期的伦敦城，那么，此时就必须使用定冠词了，如：Who knows the Beijing during 1840-1865?谁知道1840至1865年间的北京城什么样?在第二个空格处不能使用任何冠词。come to life是一个习惯表达，意思是“苏醒；复活”，如：The boy came to l
32、ife at last. 那个男孩终于苏醒过来了。因此，选项A为最佳答案。7._, we shall go on a picnic.（分数：2.50）A.If the weather were fineB.Were the weather to be fineC.Should the weather be fineD.Had the weather been fine解析：解析 该题是语法结构题，考查虚拟语气的用法。 虚拟语气用在非真实条件状语从句中表示与将来事实相反时，该从句中的谓语动词可以用三种方式表示：动词过去式、were to do、should+动词原形。那么，选项D首先可以排除掉。
33、如果用选项A或选项B，主句谓语动词也要发生相应的变化，但是该题主句的谓语动词是陈述语气，没有用虚拟语气，此时，只有使用should+动词原形的条件句才能与陈述语气或祈使语气的句子共同使用，如：If there should be another flood, what shall we do?如果再发一场大水，我们怎么办?因此，选项C为最佳答案。8.A: Whats the matter? You look sad. B: Oh, nothing much. As a matter of fact, I _ of my friends back home.（分数：2.50）A.was just
34、 thinkingB.am just thinkingC.just thoughtD.have just thought解析：解析 该题是语法结构题，考查时态的用法。 从语法角度看，四个选项都对，但是在这个对话中，A的问话打断了B的沉思或回忆。B谈论的是他刚才所做的事情，重点在过去，所以首先排除选项B和选项D。选项C只表示过去所发生过的事情，不能表示刚才/过去所做的事情这一概念。因此，选项A为最佳答案。9.He told me part of the story and that was _.（分数：2.50）A.itB.thisC.soD.that解析：解析 该题是语法结构题，考查代词tha
35、t的用法。 代词this和that可以用来上文提到过的事情，如：“I missed a good TV show last night.”“This/That is a great pity.”“我昨天晚上错过了一个很好的电视节目。”“真可惜。”如果指代下文即将要出现的事情，用this，如：This is what I want you to do: finish the task in 24 hours. 这是我想要你做的：24小时之内完成这项工作。但是在一些习惯用语中，只用that表示提到过的事情。That was it就是一个习惯用法。因此，选项A为最佳答案。10.The dog is
36、missing. He shouldnt have let the dog go out of the house alone. The possible meaning of the sentence is:（分数：2.50）A.He is being praised for having let the dog go out of the house alone.B.He is being asked to let the dog go out of the house alone.C.He is being blamed for having let the dog go out of
37、the house alone.D.He is being expected to find the dog that has gone out of the house alone.解析：解析 该题是语法题，考查情态动词should的意义和用法。 “should have done”结构可以用来表示对过去所发生的事情感到后悔(主语是第一人称)，如：I should have bought that book. 我该把那本书买了。也可以用来表示惊讶，如：He should have finished the work so early. 他这么早就完成工作了。还可以用来表示责备(主语是第二或第
38、三人称)，如：You should have waited for us. 你本该等我们一会儿。在该句子中说话人因为“他”把狗弄丢了正在对“他”表示责备和抱怨。因此，选项C为最佳答案。11.When I went into the room, I found it in a _.（分数：2.50）A.disorderB.confusionC.messD.dirt解析：解析 该题是词汇题，考查短语“in a mess”的意义和用法。 选项A和选项B可以和介词in搭配，中间不能用冠词a。in disorder意思是“混乱，紊乱”，如：His financial affairs were in co
39、mplete disorder. 他的财务状况完全是一笔糊涂账。或者用在in a state of disorder(凌乱不堪)这样的短语中，但没有in a disorder这个短语。in confusion意思是“乱七八糟；处于混乱状态”，如：He looked at me in confusion and did not answer the question. 他困惑地看着我，没有回答问题。选项D不用于此搭配中。in a mess表示“零乱；肮脏；陷于窘境”，如：The economy is in a mess.经济陷入困境。因此，选项C为最佳答案。12.The meeting _ at
40、 midnight and we all went home.（分数：2.50）A.broke throughB.stopped offC.stopped upD.broke up解析：解析 该题是词汇题，考查动词break和stop与介词或者副词构成的短语的意义和用法。 选项A中的break through意为“突破；(在科学研究上)有重大发现”，如：The demonstrators broke through the police cordon. 示威群众冲破了警方的警戒线。又如：He had finally managed to break through her reserve. 他
41、终于设法消除了她的拘谨。选项B中的stop off意为“中途停留”，如：We stopped off at a hotel for the night. 我们中途停下来在一家旅馆住了一夜。选项C中的stop up意为“堵塞；熬夜”，如：She stopped up late last night. 她昨晚熬夜到很晚。选项D中的break up意为“打碎；分裂；驱散”，如：Their marriage has broken up. 他们的婚姻已经破裂。break up也可以表示“结束”，主要强调中断、暂停。因此，选项D为最佳答案。13.What is one mans cloud is anot
42、her mans _.（分数：2.50）A.rainB.moonC.windD.sunshine解析：解析 该题是词汇题，考查习惯用法。 该句子是英语里的一句谚语。如果考生不知道这个谚语，可以从逻辑上作一些推断。句子的主语和表语意义是相反的，一件事情对一个人来说是灾难，对另一个人来说是福音。句中有cloud，那么就需要找与其意义相反的词。sunshine是再合适不过的了。因此，选项D为最佳答案。14.When her parents died, Brenda _ of the house and all its contents.（分数：2.50）A.discardedB.dispelledC
43、.disposedD.discharged解析：解析 该题是词汇题，考查词形相近但词义不同的动词的意义和用法。 选项A中的discard意思是“丢弃”，是及物动词，如：to discard ones wife遗弃妻子。选项B中的dispel意思是“驱散”，是及物动词，如：to dispel dark clouds驱散乌云。选项C中的dispose意思是“布置；安排”，与介词of构成短语表示“去掉；销毁”，如：to dispose of the stolen property销赃。选项D中的discharge意思是“释放；尽(义务)；允许离开”，是及物动词。因此，选项C为最佳答案。15.Obvi
44、ously, his remarks at the conference were spontaneous and not planned. The underlined part means _.（分数：2.50）A.substantialB.impulsiveC.simultaneousD.synthetic解析：解析 该题是词汇题，考查形容词spontaneous的意义。 题干中划线部分的spontaneous意思是“自发的，自然产生的”，如：a spontaneous expression of admiration自发的赞美之辞。 选项A中的substantial意思是“实质的；真实
45、的；实际上的”，如：substantial things实际存在的东西。选项B中的impulsive意思是“容易冲动的，凭冲动行事的”，如：an impulsive decision冲动的决定。选项C中的simultaneous意思是“同时的”，如：the policy of simultaneous development of industry and agriculture工业和农业同时并举的方针。选项D中的synthetic意思是“合成的，人造的”，如：synthetic sympathy虚假的同情。因此，选项B为最佳答案。16.The couple told the decorator that they wanted their bedroom gaily painted. The underlined part means _.（分数：2.50）A.brightlyB.light-heartedlyC.cheerfullyD.lightly解析：解析 该题为词汇题，考查副词gaily的意义。 题干中划线部分gaily是副词，意思是“in a bright and attractive way”(花哨地，艳丽地)，如：a gaily decorated room装饰华丽的屋子。 选项A中的brightly意思是“鲜艳夺目地”
