大学英语每日一练(7-24)

31.— I don’t know________.

—Because he has to look after his mother.

A. why he is leaving

B. why is he leaving

C. whether he is leaving

D. whether is he leaving

【答案】A。

【解析】考查宾语从句的陈述语序。句意：—我不知道他为什么离开了，—因为他必须要照顾他的妈妈。因为宾语从句部分要使用陈述语序所以可以排除B、D选项。然后根据回答句中文的because一词可以判断上文是询问原因的句子，why正好可以对应，故选A。

32. He is very humorous, while his brother is rather serious. That is ________ their difference lies.

A. why

B. where

C. how

D. when

【答案】B。

【解析】考查表语从句。句意：他很幽默而他的哥哥很严肃，这儿就是他们的区别所在。题干空格后面是is 动词后面的表语从句，从句中lie为不及物动词，缺少地点状语表示“在于……地方/方面”。名词性从句中，where在从句中可以充当地点状语，且为一个模糊地点。故选B。

33. A growing anxiety is disturbing the public ________ the economy will continuously decline.

A. which

B. that

C. why

D. where

【答案】B。

【解析】考查同位语从句。句意：越来越焦虑的情绪使公众不安，认为经济将持续衰退。分析句子可知________ the economy will continuously decline 是名词anxiety的同位语从句。解释说明前面的anxiety的内容。同位语从句中不缺少句子成分，所以用that来引导，故选B。

34. The man ________ was a friend of mine.

A. that you just talked to

B. whom you just talked to him

C. who you just talked to him

D. which you just talked to

【答案】A。

【解析】考查定语从句。句意：你刚说话的那个男人是我的朋友。此句中先行词在从句中作介词宾语，先行词指人。B中的whom和him重复，C中的who和him重复，因此可以排除，故选A。

35. His success is ________ by talent as by energy.

A. not so much

B. so not much

C. much not so

D. so much not

【答案】A。

【解析】考查同级比较的否定结构。句意：他的成功多靠他的努力，而不是天才。同级比较的构成not so/as...as...，故选A。

36. Seventy-five percent of the earth’s surface ________ with water.

A. is covered

B. is covering

C. were covered

D. are covered

【答案】A。

【解析】考查主谓一致。句意：75%的地球表面被水覆盖。Be covered with被……所覆盖，主语surface被百分数修饰，谓语要同百分数后面的名词保持一致。故be动词用is。故选A。

37. ________ team wins on Saturday will go through to the national championships.

A. No matter what

B. No matter which

C. Whatever

D. Whichever

【答案】D。

【解析】考查主语从句。句意：无论哪个团队在周六赢得比赛都会进入世锦赛。D由句式结构可知此空白处应选择连词引导主语从句，且在主语从句中作team的定语使用，选项中只有whatever和whichever可同时具备这两种功能，且从数个已知的队中选择一个，故选D。

38. — Excuse me. Can you tell me ________ ?

— At about 8 o’clock, sir.

A. what time the plane will reach Beijing

B. what time will the plane arrive in Beijing

C. what time the plane will arrive Beijing

D. what time will the plane get to Beijing

【答案】A。

【解析】考查宾语从句。句意：——你可以告诉我，飞机几点到北京吗?——大概8点。宾语从句用陈述语序，排除BD选项，C选项arrive需要加介词，故选A。

39. — I heard you wanted to have a further study in a foreign college.

— Yes, that’s ________ I try my best to learn English well.

A. when

B. how

C. what

D. why

【答案】D。

【解析】考查表语从句。句意：—我听说你想要在外国大学进一步深造。—是的.那就是我尽力学好英语的原因所在。题干中空格后面需要的是表语从句，that’s when…那就是…的时间;That’s how…那就是做…的方式;That’s why…那就是…的原因;what在名词性从句中可做主语、宾语、表语或定语，表示“所什么”，本题的从句中不缺主语、宾语、表语或定语，所以排除what;根据句意，故选D。

40. ________ is no doubt ________ Jennifer will come to see me this weekend as usual.

A. It; that

B. It; whether

C. There; that

D. There; whether

【答案】C。

【解析】考查同位语从句。句意：毫无疑问，这个周末Jennifer会和往常一样来看我的。分析句子结构可知，本句考查常用句型there is no doubt that…，表示毫无疑问，…;其中that引导的为同位语从句，是对前面名词doubt的解释说明;故选C。
