51. They kept trying _____ they must have known it was hopeless.?
A. if B. because? C. when D. where??
此题最佳答案为C，when在此的意思不是“当……的时候”，而是“尽管”、“虽然”的意思。又如：He walks when he might take a taxi.尽管他可以坐出租车，但他却走路。?He stopped trying when he might have succeeded next time.尽管他本来下次就可以成功的了，但他却停止努力了。?The boy was restless when he should have listened to the teacher carefully.这男孩子本来应该专心听老师讲的，但他却坐立不安。?
有许多同学只知道when表示“当……的时候”，而不知道它还有其他许多意思，除上面提到的表示“尽管”、“虽然”外，when还可表示“既然”、“考虑到”。如：Why do you want a new job when you've got such a good one already? 既然你有了这么好的一份工作，你为什么还要找新的工作呢？
52. “What did he ask you?” “_____ I would be late.”?
A. That B. When C. Where D. Whether?
此题选D，为He asked me whether I would be late.之省略。
53. “She's not a dancing teacher, is she?” “_____.”?
A. Yes, and she isn't B. Yes, but she was? C. No, but she isn't D. No, but she was??
此题最佳答案为D，可视为No, she isn't. But she was a dancing teacher.之省略，即其意为“她现在不是舞蹈教师，但她过去是”。此题也可以这样回答：No, but she used to be.
54. She's too thin. She ____ gain some weight but she _____ too little.?
A. would, ate B. will, eats ? C. would, eats D. will, ate??
此题有些难度，许多同学不知如何分析。我们先根据题目所提供的选项将句意大致概括出来：她太瘦了。她会增加体重的，但她吃得太少了。根据句首She's too thin这一所给信息可知，“她瘦”应是客观事实。按照一般的常识，“吃得少”就会导致“瘦”，“吃得多”就会导致“胖”，根据句首的信息，“她瘦”是客观事实，所以她“吃得少”也应是事实，因此第二空应填eats(即用一般现在时表示现在的事实)。根据上面的分析：“她瘦”和“她吃得少”均为现在的事实，那么“她体重会增加”就应是假设(注意句中的转折连词but)，所以第一空应填would，其实，此句可理解为其后省略了一个条件状语if she ate more (如果她多吃一点的话)。此题最佳答案选C。
55. “I like you more than her, my dear.” “You mean more than _____love her or more than she loves _____?”? A. you, me B. she, you? C. I, me D. I, you
做对此题的关键是要弄清填空句是个省略句，补充完整为：You mean that you love me more than you love her or that you love me more than she loves me? 句意为：“你是说你爱我胜过你爱她，还是说你爱我胜过她爱我？”所以最佳答案应选A。
56. “Alice, why didn't you come yesterday?” “I______, but I had an unexpected visitor.”?
A. had B. would? C. was going to D. did?
此题应选C，为I was going to come.之省略，意为“我本来是打算来的”，这与其后but I had an unexpected visitor的语境刚好吻合。注意不能选would，因为它没有“打算”之意。
57. Mrs. Brown was much disappointed to see the washing machine she had had____ went wrong again.? A. it B. it repaired C. repaired D. to be repaired?
答案解析：此题句型为have sth done, she had had repaired为定语从句，修饰the washing machine, C为正确答案。迷惑选项为B项。
58. He transplanted the little tree to the garden _____ it was the best time for it.
A. where B. when C. that D. until
答案解析：此题容易误选C, 把the garden看成是先行词，以为是where引导的表地点的定语从句。其实此题应选B。这是when引导时间状语从句。此句话的汉语意思是：他把小树在最合适的时候移植到花园。
59.?Few pleasures can equal ______ of a cool drink on a hot day.
A. some B. any C. that D. those
答案解析：：一看到few pleasures，容易错选D.但后面所设条件为a cool drink,因而正确答案应为C.
60.He just does what he pleases and never _____ about anyone else.
?A. think B. thinks C. thinking D. thought?
答案选B，thinks与前面的does为并列谓语，同用一般现在时。
61.I don't know whether to stay in teaching or _____ another job.?
A. trying getting B. to try to get C. trying to get D. try get?
答案选B，to stay in teaching与to try to get another job为两个并列的选择成分，故同用不定式。另外比较：try to do sth=设法做某事，try doing sth=做某事看看有何效果。
62.Please make my excuse at tomorrow's meeting—I've got too much work _____.?
A. to do to come B. doing coming? C. to do coming D. doing to come??
此题最佳答案为A，不定式to do与have got much work搭配，即have got much work to do (有许多工作要做)；不定式to come与much前的too搭配，构成too ... to ...句式，全句意为“我有太多的工作要做，不能来”
63. He was not an actor, who often appeared on stage, _____ a writer, writing stories.
A. but B. and C. then D. so 答案选A，主要考查not ... but ...结构。
64.There are five pairs, but I'm at a loss which _____ to buy.?
A. to be chosen B. to choose from? C. to choose D. for choosing
此题容易误选C，其实应选B。choose表示“选择”，其实是指“选择出来”(pick out)，而不是指“从……选择”，要表示后者的意思，要用choose from，有时也用choose among。同样地，下面两例中的介词from也不可省略：?
Here are some books for you to choose from. 这些书可供你选择。?
There are too many cakes to choose from. 蛋糕太多了，不知要选哪个好。?
比较： He didn't know what to choose.他不知道选什么。?
He didn't know what to choose from.他不知道从哪儿去选。
65.They kept trying _____ they must have known it was hopeless.?
A. if B. because? C. when D. where??
此题最佳答案为C，when在此的意思不是“当……的时候”，而是“尽管”、“虽然”的意思。又如：He walks when he might take a taxi.尽管他可以坐出租车，但他却走路。?He stopped trying when he might have succeeded next time.尽管他本来下次就可以成功的了，但他却停止努力了。?The boy was restless when he should have listened to the teacher carefully.这男孩子本来应该专心听老师讲的，但他却坐立不安。?
有许多同学只知道when表示“当……的时候”，而不知道它还有其他许多意思，除上面提到的表示“尽管”、“虽然”外，when还可表示“既然”、“考虑到”。如：Why do you want a new job when you've got such a good one already? 既然你有了这么好的一份工作，你为什么还要找新的工作呢？
66. He is a man of few words, and seldom speaks until _____ to.
A. spoken B. speaking ?C. speak D. be spoken
此题容易误选B，认为until是介词，后接动词时用动名词形式。其实，此题应选A，until spoken to为until he is spoken to之省略。句意为“他是个沉默寡言的人，别人不同他说话，他很少同别人说话”。按英语习惯，一些表示时间、地点、条件、方式、让步等的状语从句，若其主语与主句主语一致，且从句谓语包含动词be,那么可将从句的主语和动词be省略：?
You must study hard while (you are) young, or you will regret when (you are) old.趁年轻时要努力学习，不然到老了你会后悔的。?
I won't go unless (I am) invited. 我不会去,除非请我。?
Look out for cars when (you are) crossing the streets.过马路时要注意汽车。?
While (I was) waiting I was reading some old magazines.等的时候我在看一些旧杂志。?
He worked very hard though (he was) still rather poor in health.尽管身体还不好，但他仍努力工作。?
He will work hard wherever (he is) sent by the Party.无论党把他派往哪里,他都会努力工作。?
67.If _____ carefully, the experiment will be successful.?
A. do B. does C. done D. doing?答案选C，可视为if it is carefully done之省略。?
68. The research is so designed that once _____ nothing can be done to change it.?
A. begins B. having begun C. beginning D. begun 答案选D，可视为once it is begun之省略。
69.In that month, he earned as much as, if ____ than, $40 000.?
A. no more B. not more? C. no much D. not much??
此题最佳答案应是B。if not more than实际为if he didn't earn more than $40 000之省略。?请看类似试题（答案均选B）：??
(1) Her pronunciation is as good as, if ____than, her teacher's.?
A. no better B. not better C. no good D. not good?
(2) This church is as old as, if _____ than, that one.?
A. no older B. not older C. no old D. not old?
(3) He has read the book as many as, if _____ than, five times.?
A. no more B. not more C. no much D. not much
70.He told me the news_____, believe it or not, he had earned $1 000 in a single day.?
A. that B. which? C. as D. because??
此题容易误选B，误认为这是非限制性定语从句。其实此题应选A，that引导的是一个用以修饰名词the news的同位语从句。不少同学之所以误选B，正是believe it or not（信不信由你）这个插入成分惹的祸。
71.“Each of the students, working hard at his or her lessons,___to go to university.” “So do I.”?
A. hope B. hopes? C. hoping D. hoped??
此题应选B，句子的真正主语是each of the students，横线处填的hopes是句子谓语，其中的working hard at his or her lessons是插入句中修饰主语的非限制性定语。
?(1) Each of the students, hoping to pass the exam, _____the book.?
A. buying B. having bought C. should buy D. to buy?
答案选C，each of the students是句子主语，横线处为句子谓语，hoping to pass the exam是修饰句子主语的非限制性定语。?
(2) Many countries, for example, Mexico and Japan, _____a lot of earthquakes.?
A. have B. having C. to have D. having had?
答案选A，many countries是句子主语，横线处为句子谓语。
72.“I haven't heard from Henry for a long time.” “What do you suppose_____ to him?”?
A. was happening B. to happen? C. has happened D. had happened??
此题容易误选B，认为动词suppose后接动词用不定式。正确答案应是C，其中的do you suppose是插入成分。?
请看以下类例情形（答案均选D）：?
(1) Who do you think _____the money??
A. to steal B. stealing C. to have stolen D. stole?
(2) What do you suppose _____ him think so??
A. to make B. making C. to have made D. made?
(3) Who do you guess _____ to the station to meet her??
A. to go B. going C. to have gone D. went?
(4) What do you imagine _____ him from going??
A. to prevent B. preventing? C. to have prevented D. prevented
以下各例中的do you think (believe, guess, etc)也是插入成分，但其后接的句子用陈述句语序：?Who do you think he will marry?你认为他会同谁结婚？?What do you think we should give her?你认为我们该给她点什么呢？?When do you believe he will come?你认为他会什么时候来？?What do you guess he wants to buy?你猜他想买什么呢？
73.An awful accident, however, _____occur the other day.?
A. does B. did? C. has to D. had to?
此题正确答案应选B，句末的the other day意为“前几天”，所以句子应用过去时态，而选项D填进去不合题意，故选B。此句有两个难点：一是句中插有however一词，分散了同学们的注意力；二是所填选项B为许多同学所不熟悉的强调用法。
(1) Your mother, however, ____ say that to us that day.?
A. does B. did C. is doing D. was doing?
(2) Our math teacher, however, _____ speak English well.?
A. doing B. does C. is doing D. was doing
?以上两题答案均选B，其中的does, did均为强调用法。
74.“Where is it?” “Where is _____? I don't know what do you mean?”
A. what B. that? C. where D. so
此题应选A。许多同学认为“疑问词”只能出现在句首位置，对于选A认为不可理解。其实在某些特殊语境中，疑问词出现在句中甚至句末却是完全可能的,但这多半是因为有特殊的语境或使用的句式比较特殊。上面一题选what的原因是：上句问Where is it?(它在什么地),但听话人对此句中代词it指代什么东西并不清楚,所以他反问：Where is what?(什么在什么地方?)其实，这类用法在口语中经常使用。如：?
Who said what to whom?谁对谁说了什么？?
“Who took it?” “Who took what?”“谁把它拿走了?”“谁把什么拿走了?”?
It was so dark I couldn't tell who was who.当时一片漆黑，我分不清哪个是哪个。?
“We are ready. Let's begin.” “Ready for what?”“我们准备好了，开始吧。”“准备干什么?”?
“What are you going to do next fall?” “Next what?”“下一个秋季你打算要干什么?”“你说下一个什么?”?
They look exactly the same, and I really don't know which is which.它们看起来一模一样,我实在分不清哪个是哪个。
75.He suggested the person referred _______ put into prison.
A. is B. be C. to be D. should be
答案解析：此题应选C. referred to 过去分词作定语，be put into prison是宾语从句的谓语部分。学生由于粗心，容易误选B或者D。
76.—Must I turn off the gas after cooking ? --Of course . You can never be ___ careful with that.
A．enough B．too C．so D．very
答案解析：选B。can / could not...too是一个固定搭配，表示“无论怎样也不过分；此句话的汉语意思是：－ 做完饭后一定要把煤气关掉吗？－ 当然，你越小心越好。 有些学生误认为can never be too…是一个孤立的结构，而逐字翻译，从而误选D。
77. If you _____ stop smoking , you can only expect to have a bad cough .
A. won't B. would not C. do not D. can not
答案是A项。will除了用作表示将来时的助动词外，还可用来强调愿意或不愿意。又如：
If you will would wait a moment , I will fetch the money .
78.It's nearly seven o'clock . Jack _____ be here at any moment .
A. must B. need C. should D. can
答案是C项。根据语境空白处应填表示具有"随时可能"意义的情态动词。虽然can可以表示可能性，但它往往表示的是对这种可能性的怀疑。例如：Can he still be alive after all these years ? (这么多年之后，他还可能活在人世吗？) should除具有"应该"词义之外，还有一个含义是：will probably (将来很可能发生)又如：His uncle is working among the enemy officials now . Dangerous things should happen to him at any time . (他的叔叔现在在敌人的军营中工作，危险的事随时都可能发生在他身上。)
79.We're leaving at six o'clock , and hope _____ most of the journey by lunch time .
A. to do B. to have done C. to make D. to have made
答案是B项。要答对这道题需要两方面的知识。一是不定式的完成体用来表示这个动作发生在谓语动作之前，或是表示该动作的完成。本题中的不定式的完成体表示的正是该动作的完成，因此这句话可改写为：We're leaving at six o'clock , and hope that we will have done most the journey by lunch time . (我们将在六点时动身，希望在午饭前走完大半路程。)第二，知识是与journey连用的不同的动词所具有的不同的内涵。词组to make a journey或to go on a journey 都表示"做一次旅行"，在这两个词组里a journey是一个整体，但是如果要表示旅程中的一部分，正确的英语则使用do这个动词，例如：do some / much / most of the journey (走完这个旅程的一部分/大部分/绝大部分)
80.Do you consider it any good _____ the truck again ?
A. to repair B. repairing C. repaired D. being repairing
答案是B项。在这个句子中it是形式宾语，如果这样的句子中出现了any good , no good , any use 或 no use，就该使用动名词来作句中真正的宾语。
81.Let us not waste ______ time we have left .
the little B. little C. a little D. a little more
答案是A项，一般地说，不定代词many , little或few前是不许使用定冠词的，但是如果它们修饰的名词有特指或限定意义时，它们前面就应使用定冠词了。如：I soon finished the few books she had lent me . (她借给我的那几本书，我很快就看完了。)又如：We must make full use of the contradictions among the enemies , winning over the many and opposing the few . (我们必须充分利用敌人的内部矛盾，争取多数，反对少数。)
82.I think the doctor is able to care of _____ is the matter with your son .
A. all B. what C. whatever D. anything
答案是C项。whatever具备两个意思，其一是no matter what , 引导让步状语从句；其二是anything that , 引导名词性从句，在本题中，Whatever 引导的是一个宾语从句，whatever在这个宾语从句被用作主语。
83.It is what you do rather than what you say______matters. (2005天津卷)
A. that B. what C. which D. this
分析：答案是A。由语境和句子结构可知，该句为强调句型，被强调部分是由rather than连接的并列主语从句担当。
84. He is only too ready to help others, seldom, ____, refusing them when they turn to him.
A. if never B. if ever C. if not D. if any
B 本题考查考生在语境中灵活运用、辨析短语用法的能力，此处seldom，if ever是一个短语，是“从不，决不”的意思。
85. ——What should I wear to attend his wedding party? ——Dress ____ you like.
A. what B. however C. whatever D. how
本题however you like相当于in whatever way you like，根据语境，不难判断出B为正确答案。
