大学英语每日一练（6-5）

51. Nobody but Jane ________ the secret.

A. know

B. knows

C. have known

D. is known

【答案】B.

【解析】主谓一致。but, with等连接两个名词或代词作主语时，谓语动词应与but, with前面的名词或代词保持一致。由此可知，谓语动词应与Nobody保持一致，Nobody为不定代词，作主语时，谓语动词通常用单数形式。另外，本句是在陈述客观事实，所以应用一般现在时。故选B。

52. A famous writer’s new book My New Life will ________ next month.

A. come across

B. come out

C. come along

D. come about

【答案】B.

【解析】词义辨析。come across偶遇，无意中发现;come out出版，发表;come along出现，跟着来，进步;come about发生，产生。根据句意可知，选B。

53. —How many left-behind children are there in your class?

—________.

A. Nothing

B. Nobody

C. Neither

D. None

【答案】D.

【解析】词义辨析。nothing：没什么，没事，没有东西;nobody：无人，没有任何人，不强调数量，可用来回答who引导的问句;neither：两者都不;none：没有人，一个也没有，既可指人又可指物，强调数量，可用来回答how many/how much引导的问句。根据句意可知，此处强调数量，所以应用none来回答。故选D。

54. Since nobody gave him any help, he ________ have done the research on his own.

A. can

B. must

C. would

D. need

【答案】B.

【解析】情态动词。can have done和need have done主要用于否定句和疑问句中;must have done表示对过去情况的肯定推测，意为“一定已经做了某事”;would have done表示与过去事实相反的假设。根据句意可知，此处表示的是对过去情况的肯定推测，所以应用must have done。故选B。

55. In the last few years, thousands of films ________ all over the world.

A. have produced

B. have been produced

C. are producing

D. are being produced

【答案】B.

【解析】动词时态和语态。根据句意和时间状语In the last few years可知，本句应用现在完成时，表示动作从过去某个时间开始，延续到现在，并仍然可能延续下去。另外，films和 produce之间为逻辑上的动宾关系，所以应用被动语态。故选B。

56. They would regret for ________ a vote to a man of vision.

A. not giving

B. giving not

C. having not given

D. not to give

【答案】A.

【解析】非谓语动词。for为介词，其后应接动名词。regret for doing sth.意为“因做了某事而后悔”，其否定形式是在动名词之前加not，故选A。

57. It is no use ________ over spilt milk.

A. crying

B. to cry

C. cry

D. cries

【答案】A.

【解析】非谓语动词。在“It is no use/good/help... + doing”结构中, It是形式主语，真正的主语是后面的动名词短语。It is no good/use doing sth.意为“做某事没有好处/用处”。故选A。

58. In the exam, the ________ you are, the ________ mistakes you will make.

A. carefully; little

B. more careful; less

C. more carefully; fewest

D. more careful; fewer

【答案】D.

【解析】比较级。“the +比较级…，the +比较级…”为固定用法，意为“越……，越……”。careful的比较级是more careful;mistake为可数名词，所以应用few来修饰，其比较级是fewer，故选D。

59. It seemed only seconds ________ the big fire broke out.

A. when

B. till

C. after

D. before

【答案】D.

【解析】词义辨析。when：当……时;till：直到;after：在……之后;before：在……之前。根据句意“仅仅几秒钟大火就蔓延开了(爆发)”可知，选D。

60. When father was young, he ________ from morning till night.

A. was made working

B. was made work

C. made to work

D. was made to work

【答案】D.

【解析】非谓语动词。make sb. do sth.意为“使某人做某事”;改为被动时为：sb. be made to do sth.意为“某人被迫做某事”，不定式作主语补足语时，to不能省略。故选D。
