A. a, a B. a, the C. the, a D. the, the?

此题很容易误选B，认为第一次提到girl用不定冠词，第二次提到就应该用定冠词。但是，句中第二次提到girl时并不是特指的，此句实为一省略句，补充完整是：My friend Mary is a beautiful girl and she is a girl everyone likes to work with.?比较以下两句(第二个girl前用了定冠词，因为那是特指)：

For this he asked a girl, but the girl refused to answer him.

为此他问了一个女孩，但这个女孩拒绝回答他。?

The other day he met a beautiful girl in the park and the girl smiled at him

49 “Is there _____ here?” “No, Bob and Tim have asked for leave.”?

A. anybody B. everybody ? C. somebody D. nobody??

此题容易误选A，认为这是一般疑问句，要用anybody。其实此题应选B，主要与上下文的语境有关。全文语境为：“大家都到齐了吗?”“没有，Bob和Tim两人请假了。”假若我们将此题作如下变换，则情形就会有所不同：??

50. “Is there _____ here?” “Yes, I'm upstairs. Please come and help me.”?

A. anybody B. everybody C. somebody D. nobody?

51. “I think the teacher is wrong, _____?” “No, I don't think so.”?

A. don't you B. don't I ? C. doesn't he D. doesn't she

此题容易误选C或D，因为按照语法规则，I think后接宾语从句时，其反意疑问句与从句保持一致，但是退一步，即使按此规则，其反意疑问句也应是isn't he或isn't she之类的，而不是像C或D那样用doesn't he和doesn't she。综合四个选项，最佳答案为A，don't you为don't you think so之省略。?

52. 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?

53. “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。

54. “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.

55. 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。

56. “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。

57. “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。

58. 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。

59. 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。

60.?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.

61.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。

62.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。

63.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”

64. 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。

65.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。

66.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?

67.　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。?

68.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。?

69. 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。

70.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

71.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。

72.“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。
