）这里的“that”在从句中不充当成分，只起引导作用。
Whether she will go there is not decided （她是否会去那里还没决定。
）“whether”表示“是否”。
2、连接代词：what、who、which、whose、whatever、whichever、whoever 等What you need is more practice （你需要的是更多的练习。
）“what”在从句中充当宾语。
3、连接副词：when、where、why、how 等When the meeting will be held has not been announced （会议何时举行还未宣布。
）需要注意的是，主语从句后置时，常用 it 作形式主语，而将真正的主语从句放在后面。
例如：It is unknown whether he will come （他是否会来还不知道。
）二、宾语从句宾语从句在句中充当宾语。
比如，“I know that he is a student”（我知道他是个学生。
）“that he is a student”就是宾语从句。
引导宾语从句的连接词与主语从句类似：1、从属连词：that（在口语或非正式文体中常省略）、whether、ifHe said （that) he was busyI wonder if/whether he will come2、连接代词：what、who、which、whose、whatever、whichever、whoever 等She asked me what I was doing3、连接副词：when、where、why、how 等Could you tell me how I can get there?宾语从句的时态要根据主句的时态来变化。

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。
2．_____ is known to us all is that China has launched Shenzhou VII spaceship, ____ made the country's first spacewalk successful.A. That; whatB. What; whichC. It; whichD. As; that【答案】 B【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．It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories.A. what thatB. whichC. thatD. 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 known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties.A. As; whoseB. It; whoseC. As; whomD. 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。
5． is even more important is the earth cooled down, water began to appear on its surface.A. When; that; whenB. What; whether; asC. What; that; asD. lt; whether; as 【答案】 C【解析】【分析】这题考查从句的用法，第一空填what引导主语从句，在主语从句中what做主语，第二空填that引导表语从句，在表语从句中，as是引导时间状语从句，句意是：甚至更重要的是：随着地球的冷却，水开始出现在表面。

7．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; whetherB. focused; ifC. has focused; whetherD. 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.8．--- made her ashamed of herself?--- the lowest mark in her class.A. What; Because she gotB. Was it what; GettingC. What was it that; That she gotD. What was it that; Get【答案】 C【解析】【分析】句意：——是什么让她对她自己感到羞愧？——是她获得了她班上的最低分让她惭愧。
A中的what是句子的主语，但是because引导的从句不作主语，是原因状语从句，故排除；B的第一空是错误形式，故排除；C、D两项的第一个选项是一样的，说明第一个题干是一个强调句型，特殊疑问句下的强调句型，有what引导；第二个空是对what的回答，因为what是上一句的主语，That she got the lowest mark in her class是从句，可以作主语；而D项的get是动词原形，不能作主语，故答案为C。
【点评】考查强调句型的使用和对特殊疑问句的回答，注意问什么回答什么，也就是说疑问词what是句子的主语，回答的内容也需要在句子中能作主语。
9．________ we may find interesting is that it usually takes more to be polite.A. ThatB. WhatC. WhichD. /【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。

10．____________ matters most in learning English is enough practice.A. WhyB. ThatC. WhichD. 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。

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。
11．It matters little ______ a man dies, but _____ matters much is ______ he lives.A. how; what; howB. how; it; howC. why; it; whyD. 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。
12．Exactly _________ the potato was introduced into Europe is uncertain, but it was probably around 1565.A. whetherB. whenC. whyD. how【答案】 B【解析】【分析】句意：土豆被引进欧洲具体的事件不被确定，但是可能是在1565年左右。
