名词性从句易错大盘点

一、名词性从句

1．_______is known to us all is that Johnson broke his promise ______ he would come to help me as soon as possible.

A. It; that

B. What; that

C. As; 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。

2．_____ is known to us all is that China has launched Shenzhou VII spaceship, ____ made the country's first spacewalk successful.

A. That; what

B. What; which

C. It; which

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

A. it; that

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。

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

4．___ 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。

5． 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。

6．--- made her ashamed of herself?

--- the lowest mark in her class.

A. What; Because she got

B. Was it what; Getting

C. What was it that; That she got

D. 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。

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。

8．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。
