3．It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories.

that B. which C. that D. that what

【答案】 D

【解析】【分析】句意：有人指出，驱除焦虑所起着至关重要的作用是童年美好的回忆。本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。故选D。

【点评】考查名词性从句，本题涉及what引导的主语从句。

4． is clear to the members of the committee is that the President will not give in to their demands.

A. Who B. It C. As D. What

【答案】 D

【解析】【分析】句意：委员会成员清楚的是，总统不会向他们的要求让步。that the President will not give in to their demands.这个句子作表语； is clear to the members of the committee这是主语从句，这里缺少主语从句的连接词，并且连接词在句中作主语，it是代词，不是了；连接词，故排除B；as作主语时，是在定语从句中，故排除C；who指人，根据表语指的事情，不是人，故排除A；what在主语从句中可以作主语或宾语，指事，符合句意，故选D。

【点评】考查名词性从句，本题涉及what引导的主语从句。

5．________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties.

A. As; whose B. It; whose C. As;

whom D. It; whom

【答案】 D

【解析】【分析】句意：我们都知道，那位老科学家，过去生活很艰苦，到了八十多岁还在努力工作。第一空it is known to us all that…是个固定句型，意为“众所周知…”；第二空为介词+关系代词引导的定语从句，先行词the old scientist指人，作介

词for的宾语，只能用whom，故选D。

【点评】考查名词性从句和定语从句，本题涉及固定句式it is known to us all that…和whom引导的性定语从句。

6．Some people believe _______ has happened before or is happening now will repeat itself in the future.

A. whatever B. whenever C. wherever D. no matter what

【答案】 A

【解析】【分析】句意：一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故选A。

【点评】考查名词性从句，本题涉及\"特殊疑问词+ever\"引导的主语从句。

7．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。

8．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.

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

A. which B. that C. what D. where

【答案】 C

【解析】【分析】考查主语从句。What引导主语从句______ I call my “home”且 What在从句中充当call的宾语。故选C。

10．____ made me more unhappy was ___ the boy asked my friend to be his

girlfriend and she agreed.

A. What; that B. That ; that C. What;

whether D. It; that

【答案】 A

【解析】【分析】句意：让我更不高兴的是那个男孩要求我的朋友做他的女友，她同意了。第一空填what,它一方面在句子中引导主语从句,另一方面又在主语从句中作主语；第二空用that引导表语从句且从句中不缺成分,表示对前面情况的说明。故选A。

【点评】考查了名词性从句，本题涉及what引导的主语从句以及that引导的表语从句。

11．They lost their way in the forest, and ___ made matters worse was that night began to fall.

A. it B. which C. that D. what

【答案】 D

【解析】【分析】本题中含有一个主语从句what made matters worse，其中的what引导起这个主语从句，同时在主语从句中做主语。AC两项不能引导主语从句，which在引导名词性从句的时候总是含有疑问的语义，而本句中并没有疑问的语义。句意：他们在森林里迷路了，情况更糟糕的是天又黑了。故D正确。

12．_______ 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。

13．________ we may find interesting is that it usually takes more to be polite.

A. That B. What C. Which D. /

【答案】 B

【解析】【分析】句意：我们可能会发现有趣的是通常需要更多的礼貌。此处是主语从句做主语，从句没有引导词，缺少宾语，故答案为B。

【点评】考查名词性从句，本题涉及what引导的主语从句的应用。

14．It was he said disappointed me.

A. that; what B. what; that C. that;

which D. which; that

【答案】 B

【解析】【分析】句意：正是他说的话让我很失望。这是一个强调句型,\"it is/was that...\"是固定搭配,\"what he said\"是被强调部分, 你可以发现去掉\"it was that\"后, 句子仍然完整。 \"what he said\"做主语,主语从句中\"said\"缺宾语用what补足，故选B。

【点评】考查主语从句的强调形式。

15．They lost their way in the forest, and ________ made matters worse was that night began to fall.

A. that B. it C. what D. which

【答案】 C

【解析】【分析】句意：他们在森林里迷路了，更糟糕的是天开始黑了。根据连词and可知，本句需要一个引导主语从句的连接词，该词同时还要能在从句里充当主语。that不能在句中作成分；it不能引导主语从句；which意为“哪一个”，不符合本句语境。排除A、B、D三项。故选C。

【点评】考查名词性从句，本题涉及what引导的主语从句的应用。

16．I never doubt .

A. whether this song is worth listening to B. if this song is worth

listening

C. that this song is worth listening D. that this song is worth listening to

【答案】 D

【解析】【分析】句意：我从来没有怀疑这首歌值得去听。根据句子结构分析，本句是宾语从句，根据主句I never doubt，可知从句是陈述句，故排除A 和B，又因为listen to为固定搭配，故选D。

【点评】考查宾语从句。注意识记宾语从句的用法。

17．____________ matters most in learning English is enough practice.

A. Why B. That C. Which D. What

【答案】 D

【解析】【分析】句意：学习英语中最重要的是有足够的练习。A. why为什么；B. that引导名词性从句只起引导词作用，不充当成分；C. which哪一个；D. What什么。根据语境用what引导主语从句，并在句中做主语。故答案选D。

【点评】考查主语从句的引导词。主语从句属于名词性从句的一种，填哪个连接词要分析从句缺少什么成分，然后确定所选的词。

18．It matters little ______ a man dies, but _____ matters much is ______ he lives.

A. how; what; how B. how; it; how C. why; it;

why D. that; what; that

【答案】 A

【解析】【分析】句意：一个人如何死去并不重要，重要的是他如何生活。it为形式主语，how从句为真正的主语。What matters much （=the thing that matters much）。第一个how引导的是一个主语从句；it作形式主语；what引导的是主语从句；第二个how引导的是表语从句。故选A。

【点评】考查名词性从句，本题涉及主语从句和表语从句的应用。

19．_______ makes me feel worried is _______ singing stars are centered on by masses of teenagers today.

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

that D. That; what

【答案】 C

【解析】【分析】句意：让我感到担忧的是，今天的歌星是以青少年为中心的。分析句子可知，主语从句中的谓语动词makes 缺少主语，主语从句中缺少宾语一般用

what，因此选择 what 来引导主语从句；系动词 is 后面的表语从句句意完整，不缺少成分，因此选择 that 引导表语从句。分析选项可知C项符合题意，故选C。

【点评】考查名词性从句，本题涉及 what引导的主语从句和that引导的表语从句的应用。

20．________ manners are very important in every country is known to all，but the trouble is that different countries have different ideas about ________ good manners are.

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

that D. What; what

【答案】 A

【解析】【分析】句意：众说周知，礼貌在每一个国家中都是非常重要的，但是麻烦是，不同的国家对于什么是良好的礼貌有着不同的认识。逗号前有两个谓语动词，一个是are，一个是is known，故是两句话，需填连词连接这两句话，根据句意可知，前面是主语从句，故填that，此处的that，只起连接作用不作任何成分。about是介词，其后是个句子故应填连词把这两句话连接起来，所缺词作are的表语，故填what。因此选A。

【点评】考查名词性从句，本题涉及that引导的主语从句和what引导的宾语从句。

would come to help me as soon as possible.

which D. What; which

【答案】 B

【解析】【分析】句意：我们都知道，Johnson违背了他会尽快来帮助我的诺言。分析句子结构可知，第一空为主语从句，从句中缺少主语，所以用what，第二空为同位语从句，从句结构完整，所以用that解释promise的内容，故选B。

【点评】考查名词性从句，本题涉及主语从句和同位语从句。

【答案】 B

【解析】【分析】句意：——当你参观雅典卫城时，你印象最深的是什么？——使我印象最深的是什么将从前宏伟的宫殿变成了今天惨不忍睹的样子。强调句型的特殊疑问句式：疑问词（如what） is it that+其它，本句强调的是什么使得从前宏伟的宫殿蜕变的，所以用表示内容的what，选B

【点评】考查主语从句和强调句，本题强调主语从句的引导词。

23．We believe ________ you have been devoted to ________ naturally of great necessity.

A. that; being B. all that; be C. that all;

are D. what; is

【答案】 D

【解析】【分析】句意：我们相信你所投入的当然是非常必要的。分析句子可知，believe后接宾语从句，宾语从句中you have been devoted to缺少宾语，表示事物故用what；what you have been devoted to为主语，从句作主语，谓语动词用单数，故选D。

【点评】考查名词性从句和主谓一致，本题涉及what引导的主语从句和一般现在时。

24． ---- Let's send him home. Do you know _________?

---- I have no idea.

A. where does he live lives D. he lives where

B. where he lives C. he where

【答案】 B
