1．—What impresses you most when you visit the Acropolis ?

— ________ it is that has brought the grand palace into today's terrible scene.

A. Where

B. What

C. How

D. When

【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。

A. That; what

B. What; which

【解析】【分析】句意：众所周知，中国已经发射了神州7号宇宙飞船，这是中国首次成功的太空行走。第一空处为主语从句，从句缺少主语，需用what引导；第二空所在句子是个定语从句，先行词为整个主句的内容，从句中缺少主语，需用which引导。故选B。【点评】考查名词性从句和定语从句，本题涉及主语从句和非限制性定语从句的应用。

3．While some behaviors may seem strange to you, remember you consider normal probably seems just as unusual to others.

B. what; that

C. that; what

D. which; that

【答案】 C

【解析】【分析】句意：虽然有些行为对你来说可能很奇怪，但请记住，你认为正常的行为对别人来说可能也不寻常。第一空为宾语从句，从句结构完整用that起连接作用，第二空为主语从句，从句中consider缺少宾语，应该用what，故选C。

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

A. what 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。

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引导的限制性定语从句。

6．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.
