一、名词性从句

1．_______ is troubling me is ______ I don't understand ________ he said

A. What; that; what what D. Why; that; which

B. What; what; what C. That; that;

【答案】 A

【解析】【分析】句意：我烦恼的是我不明白他说的话。第一空是主语从句，从句中缺主语，要用What；第二空是表语从句，从句不缺成分，所以要填that；第三空是宾语从句，从句中的动词understand缺宾语，要填what。故选A。

【点评】考查名词性从句，本题涉及主语从句，表语从句和宾语从句的应用。

2．It________that the road will be closed tomorrow for repairs.

A. was announced B. has been announced

C. had been announced D. would be announced

【答案】 B

【解析】【分析】本题考查动词的时态和语态。题干句子中that到句子结束是宾语

从句，且从句动词用“will＋动词原形”表示将来，由此推断出空白处谓语动词应用现在的某种时态，在所给四个选项中，只有B项正确。

【点评】考查现在完成时的被动语态，其结构是have/has +been +done。需要注意宾语从句的时态。主句用现在时，从句所需的任何时态。

3．In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question.

A. focused; whether B. focused; if C. has focused;

whether D. has focused; if

【答案】 C

【解析】【分析】考查时态和主语从句。根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。故选C。

【点评】主语从句主要有三类：

1）（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。（2）用连词 whether 引导的主语从句:whether有含义（是否）,在句中不做成分,不

可以省。例如：Whether she is coming or not doesn't matter too much.她来不来都无关紧要。注意：if不能引导主语从句。

2）用连接代词引导的主语从句（在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分）.例如：What you need is more practice.你所需要的是更多的训练。

3）用连接副词when, where, why, how引导的名词性从句（其连接副词有含义,在句中作状语。）例如：Where we should leave it is a problem.

4．Located between the 16th and the 18th floor, ______ I call my “home” is more like a “bird's nest”.

7．It is a rule in his family that _______ comes home first should cook the dinner.

A. anybody B. who C. whoever

D. who that

【解析】【分析】句意：在他的家里有个规定，就是先到家的人要先做饭。 whoever 有两个词义：1no matter who，在这种用法时引导一个让步状语从句；2anybody that，在这种用法时，它连接一个名词性从句，在本题中它连接的是主语从句。这里就是第二个用法。所以选C。

8．_______ you don't like him is none of my business.

A. What B. Who C. That D. Whether

【答案】 C

【解析】【分析】句意：你不喜欢他，跟我没有什么关系。you don't like him为主语从句，其内容已经是完整的，所以用that，且引导主语从句的that不能省略。
