25、g sentences is CORRECT?（分数：2.50）A.During the 1980s that the trade between the two countries reached its highest point.B.It was in the 1980s that the trade between the two countries reached its highest point.C.That it was in the 1980s that the trade between the two countries reached its highest point

26、.D.It was the 1980s that the trade between the two countries reached its highest point.解析：解析 该题是语法题，考查强调结构It is/was.that.的用法。 在这个强调句中，受到强调的部分是时间状语。如果用选项A，句中的that就是多余部分。如果用选项C和选项D，句子的意义不完整。因此，选项B为最佳答案。2.The sun rises in the east and sets in the west, so it seems as if the sun _ round the earth.（分数：2.

27、50）A.had circledB.was circlingC.might circleD.were circling解析：解析 该题是语法结构题，考查虚拟语气在as if引导的从句中的用法。 虚拟语气可以用在as if引导的方式状语从句中。如果从句中的动词与主句的动词同时发生，该动词用过去式，如：She loves the children as if they were her own. 她爱这些孩子，就好像他们是她亲生的一样。如果从句中的动词表示的动作先于主句的动词发生，该动词用had+动词过去分词，如：He talked about America as if he had been

28、here.他谈起美国来就像他去过似的。如果从句中的动词表示的动作后于主句的动词发生，该动词用would/could+动词原形，如：The little girl looks as if she would cry. 小女孩看起来要哭了。题干中动词seem和circle是同时发生，所以选项A(表示circle先于seem发生)和选项C(表示circle后于seem发生)都是错误的。虚拟语气结构中的助动词应该是were而不是was，那么选项B也不能选用。因此，选项D为最佳答案。3.How close parents are to their children _ a strong influenc

29、e on the character of the children.（分数：2.50）A.haveB.hasC.havingD.to have解析：解析 该题是语法题，考查句子主谓一致的用法。 在该句子中，主语是一个从句：How close parents are to their children，缺失的是谓语动词。当主语从句出现时，句子的谓语用单数形式，其他选项不符合要求。因此，选项B为最佳答案。4.In the sentence It is no good reading in dim light , the italicized phrase is _.（分数：2.50）A.an o

30、bjectB.an adverbialC.a complementD.a subject解析：解析 该题是语法结构题，考查动名词作主语的用法。 在句子“It is no good reading in dim light”中，it是形式主语，真正的主语是动名词短语reading in dim light。句子It is no use doing sth. 也是一样的句子结构，动名词作句子的真正主语。因此，选项D为最佳答案。5.It is important _ you to get there in time.（分数：2.50）A.thatB.forC.ofD.whether解析：解析 该题是

31、语法结构题，考查带逻辑主语的动词不定式的用法。 在该句子中，it是形式主语，真正的主语是for you to get there in time。这是一个带逻辑主语的动词不定式，当它作主语时，通常要使用形式主语，如：It is necessary for China to catch up with the developed countries. 中国赶上发达国家是必要的/中国有必要赶上发达国家。因此，选项B为最佳答案。6.What _ would happen if the director knew you felt that way?（分数：2.50）A.do you supposeB

32、.you supposeC.will you supposeD.you would suppose解析：解析 该题是语法结构题，考查句子的语序。 在该句子中，do you suppose相当于一个插入语。类似的表达还有do you think，如：What do you think she will say if she knows the news?如果她知道了这个消息，你觉得她会说什么?因此，选项A为最佳答案。7.I dont have any money with me. Do you? he asked. He said _.（分数：2.50）A.he didnt have any m

33、oney with him and asked me if I hadB.he doesnt have any money with him and I doC.he didnt have any money with and asked me if I doD.he didnt have money and asked me解析：解析 该题是语法结构题，考查如何将直接引语变成间接引语。 题干中有两个句型：否定陈述句I dont have any money with me和承前省略谓语和宾语的一般疑问句Do you (have any money with you)。把这两个句型变成间接引语

34、时，第一句作陈述句引述，用动词say；第二句作一般疑问句引述，要加动词ask。从时态和第二个句子的动词使用来看，选项B可以首先排除。选项C在转述一般疑问句时出现时态错误(I do)，也应排除。选项D引述意思表达不完整，也不能选用。因此，选项A为最佳答案。8._, he can now only watch it on TV at home.（分数：2.50）A.Not obtaining a ticket for the matchB.Having not obtaining a ticket for the matchC.Not having obtained a ticket for th

35、e matchD.Not obtained a ticket for the match解析：解析 该题是语法结构题，考查现在分词的用法。 动词短语obtain a ticket的逻辑主语与句子的主语应该是一致的，都是he，那么就该用现在分词，选项D就可以排除。现在分词在该句子中作原因状语，其结果是现在他只能在家里看比赛的电视转播。要表达这样的先后顺序，就要使用现在分词的完成式，所以选项A可以排除。分词否定形式中的not应该在doing前面，所以选项B可以排除。因此，选项C为最佳答案。9.Which of the following sentences is CORRECT?（分数：2.50）

36、A.In did come the teacher and the class began.B.In the teacher came and the class began.C.In did the teacher come and the class began.D.In came the teacher and the class began.解析：解析 该题是语法结构题，考查修辞倒装的意义和用法。 倒装主要分为语法倒装和修辞倒装。语法倒装是必须发生的，否则就会出现语法错误，而修辞倒装可以发生也可以不发生，只会带来表达效果上的差异。本题中的倒装就属于修辞倒装。当in、out、away、u

37、p、down、off等副词用于句首时常常用倒装形式，以传递表达的生动性，如：Up went the rocket into the space. 火箭一飞冲天。该倒装形式要求将谓语动词放在主语前面，即In came the teacher and the class began。也可以不倒装，即The teacher came in and the class began。因此，选项D为最佳答案。10.The party began at eight. So they _ dine at seven.（分数：2.50）A.mayB.mustC.ought toD.should解析：解析 该题是

38、语法题，考查情态动词的意义和用法。 情态动词may表示“允许；可能”，不合句子意义。选项C和选项D意义相近，表示“应该”，如：Everyone in our position ought to/should be able to do something. 我们在岗的每个人(按道理)都应该能做些事情。选项B中的must表示“必须，不得不”。因此，选项B为最佳答案。11.In general, the amount that a student spends for housing should be held to one-fifth the total that can be used fo

39、r living expenses. The underlined part means _.（分数：2.50）A.availableB.acceptableC.applicableD.advisable解析：解析 该题是词汇题，考查形容词的意义和用法。 选项A中的available意思是“可供利用的，可获得的”。选项B中的acceptable意思是“可接受的，合意的”，如：Children must learn socially acceptable behaviors. 儿童必须学会社会上认可的行为举止。选项C中的applicable意思是“能应用的，可适用的”，如：Much of the

40、 form was not applicable to me. 表格中很多部分不适用我的情况。选项D中的advisable意思是“可取的，明智的”，如：It is advisable to practise each exercise individually before doing the whole routine. 最好先一节一节地练，然后再做整套动作。因此，选项A为最佳答案。12.I should like to rent a house, modern, comfortable and, _, in a quiet neighborhood.（分数：2.50）A.all in al

41、lB.above allC.after allD.over all解析：解析 该题是词汇短语题，考查惯用语的意义和用法。 选项A中的all in all意思是“总而言之”，如：All in all it had been a great success. 总之，那是个巨大的成功。选项B中above all表示“(相比较而言)最主要的，最重要的”，如：Above all, make sure you keep in touch. 最要紧的是你们一定要保持联系。选项C中的after all表示“毕竟”，如：You should not have been so hard on him; after

42、 all, he is only a little child. 你不应该对他如此严厉，毕竟他还是一个小孩子。选项D中的over all表示“从一头到另一头(尤指从船头到船尾)”。因此，选项B为最佳答案。13.Once Manchester was the home of the most productive cotton mills in the world. The underlined part means _.（分数：2.50）A.On one timeB.By one timeC.At one timeD.Of one time解析：解析 该题是词汇题，考查介词短语的意义和用法。

43、题干中划线部分的意思是“曾经”。在四个选项中，只有选项C中的at one time表示“过去曾经”，如：At one time hospital doctors were men, but today there are many women doctors as well. 过去医生都是男的，现在也有很多女医生了。其他几个搭配是错误的。因此，选项C为最佳答案。14.The newspaper did not mention the _ of the damage caused by the fire.（分数：2.50）A.rangeB.levelC.extentD.quality解析：解析

44、该题是词汇题，考查意义相近的名词的意义和用法。 选项A中的range意思是“幅度；范围”，常强调变化的差异性和职权等的范围，如：The hotel offers a wide range of facilities and services. 酒店提供一系列设施和服务。选项B中level表示“水平；程度”，强调在序列中的位置，如：I finally found my own level in the business world. 我终于在生意场上找到了自己的位置。选项C中的extent表示“程度”，强调广度、长度和大小，如：No one knows the extent of his deb

45、ts. 没有人知道他负债多少。选项D中的quality表示“质量，品质”，不符合题意。因此，选项C为最佳答案。15.It is quite necessary for a qualified teacher to have good manners and _ knowledge.（分数：2.50）A.extensiveB.learnedC.intensiveD.comprehensible解析：解析 该题是词汇题，考查形容词的意义和用法。 选项A中的extensive意思是“广阔的，广泛的”，如：extensive knowledge广博的知识，extensive funds大笔经费。选项B

46、中learned表示“有学问的；学术性的”，如：a learned professor博学的教授，a learned journal学术性刊物。选项C中的intensive表示“强烈的；精深的”，如：His disappearance has been the subject of intensive investigation. 他的失踪一直是大力调查的重点。选项D中的comprehensible表示“可理解的，易于了解的”，如：The book is comprehensible to the average reader. 这本书一般读者都能懂。该题容易误用learned，但learned knowledge(有学问
