名词性从句考点+例题_全面解析1

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．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。

3．___ 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。

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．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。

6．____ 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。7．—Tell me something about your adventure in the rainforest, please.

— We lost our way in the forest and ___ made matters worse was ___ night began to fall.

A. what; that

B. it; that

C. it; because

D. what; because

【答案】 A

【解析】【分析】考查名词性从句的连接词。第一空what作主语从句的主语；第二空为表语从句的that。

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。

9．_______ you don't like him is none of my business.

A. What

B. Who

C. That

D. Whether
