1、1词汇与语法结构一. 考试内容与要求 大学英语（B）大纲的要求第三部分试题为词汇与结构。总分为 30 分，考试时间为 30 分钟。此题又分 Section A 和 Section B 两部分。下面我们先看 Section A：单句选择。词汇和语法结构部分共设 20 个单句，每句 1 分，共 20 分。 大纲对考生词汇的要求为：“能认知 3000 个单词，并熟练掌握其中的 1800 个单词以及其基本的搭配。 ” 语法的要求为：能掌握基本的英语语法知识，并能在听、说、读、写、译中较正确地加以运用。 词汇和语法结构部分的考试目的是测试考生运用词汇，短语及语法结构的能力。二. 词汇部分答题技巧 词汇部
2、分的考点为：名词，代词，介词，连词，形容词和副词，数量词，情态动词，动词短语的搭配和用法。 词汇试题的正确选择在很大程度上取决于考生词汇量的大小，以及运用词汇能力的强弱。但是了解一些解题技巧也会对考试有一定的帮助。下面简单介绍几种词汇测试题中常见的应试技巧。(一). 根据词的固定搭配选择答案英语中有许多约定成俗的固定搭配， 试题设计者把其他部分给出，但是其中有的项未给出，让考生从四个选项中选出最佳答案，填入句子使其意义完整。如：You should have been more patient _ that customer.A. of B. with C. for D. atbe patie
3、nt with sb. 是一个固定搭配，意为“对某人有耐心”，因此该题的答案是 B.（二）. 通过区别同义或近义词选择答案做这类的题，选择时要注意区分词与词之间的细微差别，同时要注意在本题上下文中的关系，最好做出选择。如：In the theatre the actors are very _ to the reaction of the audience.A. sensible B. sensitive C. emotional D. positive答案是 B. 本题的句意是：“ 在剧院里，演员对观众的反应很”。四个选项意义分别为 A. sensible 可以察觉的； B. sensiti
4、ve 敏感的； C. emotional 容易动感情的； D. positive 积极的。根据题意判断只有选项 B 放在原句中符合逻辑。（三）. 根据上下文的逻辑含义以及主从句之间的关系选择答案有些逻辑关系比较明显的句子，选择答案时，可以根据所给部分之间的提示，选出合乎逻辑的答案；有时，也可根据主从句之间或句子其他部分之间的关系选出可以表明这种关系的词或词组。1利用表示增加与递进关系的词这样的词包括：and, again, also，too, besides, moreover, furthermore, but, in addition to 等。例：The house is very _,
5、 and furthermore, its too far from the town.A. neat B. spacious C. expensive 2D. fashionable分析四个选项，我们可以看到选项中的所有单词都可以用来修饰句子的主语房子。句子中间表示递进关系的 furthermore 在帮助我们判断时非常关键。它后面所跟的是描述房子离城太远，这是房子的缺点。根据逻辑推理，它前面的分句说明的也一定是缺点。因此选项中的 A、B、D 都不对，因为它们都是在说明房子的优点，故而答案只能是 C，若题句中的 and furthermore 改成 but ，那么选项就要改变了。2利用表示比
6、较与对比关系的词这样的词包括:but, however, although, in contrast, instead of 等。例：A lamp is concrete and you can touch it, but its brightness is _.A. academic B. abstract C. absurd D. absolute句子中表示对比关系的连接词是 but，从这一信号词中我们可以推断句子前后两部分所阐述的内容正好是相对的，与 concrete 相对的是 abstract，因此 B 是本题答案。3利用表示因果关系的词这样的词包括：because ,so, as a
7、 result, thus, consequently, therefore 等。例：He is a very _ person because he has done a lot of good things for the local people.A. respectableB. respectful C. respective D. respecting本句后半部分是由 because 引导的原因状语从句，意思是“他为当地人做了许多好事” ，从这一原因中，我们自然能推断出他应该受到别人对他的尊敬。表示“被人尊敬的，值得尊敬的”应当是 A。4. 利用表示让步关系的词这类词包括：if, a
8、lthough, in spite of, while, whereas 等。例：Although Asian countries are generally more _ in social customs than Western countries, there have been several notable examples of women leaders in both China and India.A. consistent B. comprehensive C. confidentialD. conservative本句 although 引导的是让步状语从句，因此可以推
9、断主句中的事实与前面所出现的有关亚洲国家的特点正相反。与后半句中所阐述的“中国和印度都有一些著名的妇女领袖”这一事实相反的亚洲国家的特点应当是“在社会习俗方面比西方国家要保守” 。因此选项中的 D 是正确答案。（四）. 根据词法常识判断选择有些词汇测试题，从词的意义去考虑，填入多个选择项都可以。在这种情况下，如果借助语法结构对题目进行分析，往往可以找到正确答案。例：Experts say walking is one of the best ways for a person to _ healthy.A. preserve B. stay C. maintain 3D. reserve从四个
10、选项动词的词义来看，哪个都行。但动词后面直接跟形容词作表语的只有stay，其它三个动词都是及物动词，后面应当接宾语。因此答案是 B。（五）. 排除法在做词汇题时，常会遇到一时难以判断哪一个是正确答案的情况。这时不妨从不符合题义的选项着手，将非正确答案逐一排除，剩下的多半就是正确答案。此方法同样适用阅读理解，语法及完形填空部分的试题，在此不再一一举例。练习：1.

15、g答案 A。2)Please be sure to telephone me the next time you _.A. will come B. would come C. shall come D. come 答案 D。2.在“This is the first time”结构中，后面的从句用现在完成时。句子开头也可以用 it 代替 this例：This is the first time that I have met Jane.3.在“It/This is +形容词最高级+名词后面的从句中，用现在完成时。”例：This is one of the best books _ on th
16、e subject.A. that have ever been written B. which have ever been writtenC. that has ever been written 5D. whatever have been written 答案为 A。 4.在“It is/has been时间段 since后边用过去时。”例：It has been twenty years since I left my hometown.5.在“no soonerthan”和“hardly when”结构中，主句部分用过去完成时，从句部分用过去时。例如：1)I had no soo
17、ner returned than he called.2)We had hardly begun when we were told to stop.6.在“It is (high) time 后边的从句中用过去时。”例：It is time that we had a rest.（二）语态1. 语态是表示主语与谓语之间关系的一种形式。英语有两种语态：主动语态和被动语态。 考查时态与语态的题通常结合在一起，尤其是被动语态，除了注意它的一般时态之外，还要注意它进行时态及完成时态的变化。如：He told me that a highway was being built here.他告诉我这里
18、正在建造一条高速公路。2. 另外还需注意有些动词，其形式虽是主动，但具有被动的含义。1）当感官动词作系动词时,例如：Good medicine tastes bitter.良药苦口。This material feels very soft.这种衣料摸起来非常柔软。62）还有一些及物动词作不及物动词时，也可以表示被 动含 义，如：This pen doesnt write well.这支笔不好使。此类动词不多，常见的有 cut, lock, open, peel, read, sell, shut, wash, wear, write 等。练习：1.

23、s dying C. dies D. died练习答案：1-10 CCAAD AABCB（三）情态动词1情态动词无人称变化，在句子中和动词原形一起组成谓语。只有 ought 后面接 to do。情态动词后接完成时的用法:情态动词用来表示能力、允许、许诺、可能、必须、劝告、意愿等概念或态度。 2must 现在完成时结构：这一结构表示对过去一个动作比较有把握的猜测。例：I believe he _ an accident, otherwise he would have arrived on time.A. would have had B. could have hadC. should hav
24、e hadD. must have had答案为 D。3should (ought to )have done 用来表示本来应该做却没有做的事情。例：Im sorry I couldnt get in touch with him before he left, I _ him earlier.A. had a telephone B. have phoned C. should have phoned D. should be phoned答案是 C。中文意思是“ 我很抱歉我没能在他走之前和他联系上，我本应早点儿给他打电话的。 ”4could现在完成时，表示本来能做的事情而没有做。例：Mar
25、y _ that coat, but she chose to lend the money to a needy neighbour.A. could have bought B. must have boughtC. can buy D. could buy答案为 A。玛丽本来可以买那件大衣的，但是她把钱借给一个更急需的邻居了。（四）虚拟语气 虚拟语气是动词的一种特殊形式，用来表达说话人的愿望、请求、意图、建议、惊奇、设想等。虚拟语气是英语语法的难点，考生必须熟练掌握。以下从五个方面介绍。1虚拟条件句中虚拟语气的运用：虚拟条件句从时间上又分为与现在事实相反，与过8去事实相反，与将来事实可能
26、相反三种情况。表示与现在事实相反的，if 从句用过去式，主句用 would（或 could, should, might）加原形动词。与过去事实相反的，if 从句用过去完成时，主句用 would（或 could, should, might）+have done 结构。与将来事实可能相反的，if 从句用 should (或 were to)加动词原形，主句用 would 加动词原形。1）If a better material _, the strength of the part would have been increased.A. had been usedB. had been us
27、ingC. being used D. using根据前面的讲解，正确答案为 A。 2）Had the weather been good, the children _ out for a walk.A. had gone B. could have gone C. would go D. went答案为 B。与过去的事实相反。当 if 从句中含有 were, had, should 这三个词时，if 可以省略，主谓倒装。2某些动词后的宾语从句以及某些名词后的表语或同位语从句中虚拟语气的运用，这些动词或名词包括：suggest(suggestion),propose(proposal),ad
28、vise (advice),demand, insist, order, request, require, recommend, desire, ask, decide 等表示建议、命令或要求的词。在这些从句中，谓语形式为 should 加动词原形， should 可以省略。例：The generals command was that the soldiers _ their fort and carry out more 9important task.A. would leave B. leave C. left D. have left 答案为 B。3在 It is desired(
29、或 desirable), It is important 等结构后面的主语从句中，动词用原形或should+原形动词。这些结构有： It is suggested, It is requested, It was ordered, It is necessary, It is essential. It is vital, It is urgent, It is impossible, It is preferable, It is advisable, It was proposed 等。例：Its desired that she _ to teach us at least twice
30、 a week, A. comes B. will come C. come D. may come答案为 C。4在 would rather, as if/though 以及 wish 后边 that 从句中虚拟语气的运用。1）I am too busy these days. I would rather all of you _ next month for a dinner.A. come B. would come C. came D. have come10答案为 C。would rather 后面的从句中，动词形式用过去式。2）He talks as if he _ everyt
31、hing in the world.A. knows B. knew C. had known D. would have know正确答案为 B。在 as if/though 后边的方式状语从句中，表示与现在事实相反或对现在的情况有所怀疑，动词用过去式；如果表示的是想象中的过去的动作，用过去完成时。本句表示对现在的情况有所怀疑。3）You look as if you had seen a ghost.此句中 as if 后边是说话人想象中的过去的动作，所以用过去完成时。4）I wish I knew his address.在 wish 后边的从句中，如果指现在或将来的愿望，动词用过去式。
32、这句话告诉我们说话人并不知道他的地址。5）Peter wishes that he _ law instead of literature when he was in college.Acould study B. studiedC. had studied D. would study答案为 C。在 wish 后边的从句中，如果表示过去没有实现的愿望，动词用过去完成时。5在 It is (high) time 后边的 that 从句中，动词用过去式，表示该做某事了。11例：Dont you think it is time you _ smoking?A. give upB. gave u

37、ave been B. would be C. should be D. had been练习答案：1-10 ADBDC ACBBA（五）非谓语动词 动词非谓语形式包括不定式，动名词和分词，它们在句子中不能充当谓语，可以分别充当主语、表语、宾语、定语和状语。虽然非谓语形式不能充当谓语，但它们仍然保留了动词的某些特征，比如说它们可以有自己的宾语，补足语或状语以及自己的逻辑主语，能成为句子的独立成分。动词非谓语形式有一般时、进行时和完成时三种形式以及相应的主动与被动形式。在解答有关动词非谓语形式的试题时，应特别注意以下几点：1英语中有些动词后跟不定式作宾语，有些动词后面则接动名词作宾语，还有一些动
38、词的后边既可以接不定式，也可以接动名词，有时意义不变，但有时却在意义上大不相同，所以必须牢记有关非谓语形式的基本知识。1）We shall appreciate _ from you soon.A. being heard B. hearingC. to hear 13D. having been heard答案是 B。appreciate 这个词后面只能接动名词，且应该是其一般式。2）The man in the corner confessed to _ a lie to the manager of the company.A. have told B. be toldC. being
39、toldD. having told短语动词 confess to 中的 to 是介词，不是动词不定式符号，因此选项 A 和 B 可以排除。选项 C 是动名词的被动式，而动名词后边已经有了宾语 a lie ,因此动名词不能是被动式，因此正确答案是 D。用完成形式的动名词表示这个动作在主要动词之前已经发生。3）We all feel sorry for _ for so long after your arrival.A. keep you waiting B. having kept you waiting C. waiting for youD. keep you wait答案为 B。2非谓
40、语动词作宾语补充语时，要弄清哪些动词后面可以跟不定式作宾补，哪些动词后面可以跟分词作宾补。1）Mr. and Mrs. Smith didnt expect the house _ so well.A. to be decoratedB. to decorateC. be decorated14D. decoratingdecorate 是及物动词，因此可以排除 B 和 D，C 项缺了不定式的符号 to，因此正确答案为 A。2）There was so much noise that the speaker couldnt make himself _.A. hearing B. being
41、heardC. to hearD. heardhear 在本句中是及物动词，据此可以排除 A 和 C，B 项选择形式不对，因此 D 是正确答案。3）The manager has his employees _ a business report every week.A. to writeB. writtenC. writing D. write答案为 D。have 和 get 后面接宾补时，要用过去分词或无 to 不定式。4）we are going to have our office _ to make room for a new engineer.A. to rearrangeB.
42、 rearrange C. rearranged D. rearranging答案为 C。153非谓语动词作状语时，尤其是分词作状语时，要注意分词的逻辑主语必须和句子的主语一致。例：Arriving at the bus stop, _ waiting there.A. he found a lot of peopleB. a lot of people wereC. he found a lot of peoples D. people were found根据上面所述，可以首先排除 B 和 D，C 项中的 peoples 结构不对，正确答案只能是 A。4掌握好非谓语动词形式时态和语态的正确
43、使用。如果非谓语动词所表示的动作发生在主要谓语动词所表示的动作之后或同时，用一般式，如果非谓语动词表示的动作在主要谓语动词所表示的动作之前，则用完成式。非谓语动词的逻辑主语是动作的发出者还是接受者决定了应当用主动式还是被动式。例：The famous novel is said _ into Chinese.A. to have translated B. to be translateC. to have been translated D. to translate答案为 C。练习：1.
