1．______ makes the school proud is ______ more than 90% of the students have been admitted to universities.

A. what; because

B. that; because

C. that; what

D. what; that

【答案】 D

【解析】【分析】句意：让学校骄傲的是，超过90%的学生被重点大学所录取。第一空主语从句中缺少主语，指代事情，故用what;第二空为表语从句，且从句中不缺少成分，故填关系词that。故选D。

【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。

2．___ surprised me most was ____the girl passed the driver test.

A. That; that

B. What; how

C. What; that

D. That; why

【答案】 C

【解析】【分析】句意：最让我吃惊的是那个女孩通过了驾驶考试。___ surprised me most是一个主语从句，从句中缺少主语，故填what；____the girl passed the driver test 是一个表语从句，句中不缺少成分，故填that。因此选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。

3．________ 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i t is known to us all that…和whom引导的限制性定语从句。

4． is even more important is the earth cooled down, water began to appear on its surface.

A. When; that; when

B. What; whether; as

C. What; that; as

D. 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。选C。

5．Has it been announced ______?

A. when are the planes to take off

B. that are the planes to take off

C. where are the planes to take off

D. when the planes are to take off

【答案】 D

【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。

【点评】考查名词性从句，it作形式主语，关系副词when引导的从句作真正的主语。

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.

7．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。
