高中英语易错题集锦——名词性从句
高中英语易错题集锦——名词性从句
期中考试马上就到了，多看一些易错题，避免犯同样的错误，也不失为一种很好的考前复习策略呢！
今天，孙老师总结的高中生在平时英语练习和考试中容易出错的题目是关于名词性从句的，名词性从句主要考查连接词的选择。
做名词性从句关键在于三点，一是判断名词性从句的起始；二是判断名词性从句具体是主语从句、宾语从句、表语从句还是同位语从句；三是从句中是否缺成分。
1. 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
【答案与解析】选D。what made matters worse 是主语从句(注意其后有谓语动词was)。
2. Patience is a kind of quality —and that is ______ it takes to do anything well.
A. what
B. which
C. which
D. how
【答案与解析】选A。what 引导的是表语从句，相当于the thing that it takes to do anything well。
3. It has come to my notice _______ some of you have missed classes.
A. what
B. which
C. that
D. when
【答案与解析】选C。that 引导的是一个主语从句，句首的it为形式主语。
4. ——What were you trying to prove to the police?
——I was last night.”
A. That
B. When
C. Where
D. What
【答案与解析】选C。答句为省略句，其完整形式为I was trying to prove to the police where I was last night，在此where 引导的是一个宾语从句。类似地，下面选C：
——_______ made her struggle to become an artist so hard? ——_____ she was a woman.
A. What, What
B. That, That
C. What, That
D. That, What
5. Country life gives him peace and quiet, which is ______ he can’t enjoy while living in big cities.
A. that
B. why
C. where
D. what
【答案与解析】
选D。what 引导的是表语从句，what做enjoy的宾语。
6. It is pretty well understood _______ controls the flow of carbon dioxide in and out the atmosphere today.
A. that
B. when
C. what
D. how
【答案与解析】选C。句首的it 是形式主语，空格处所填词用于引导主语从句。由于该主语从句中又缺主语，故排除A、B、D。(注意：不能选A，因为that 引导名词性从句时不能充当句子成分)
7. _______ she couldn’t understand was ______ fewer and fewer students showed interest in her lessons.
A. What; why
B. That; what
C. What; because
D. Why; that
【答案与解析】选A。第一空填what，是因为该主语从句中的动词understand 缺宾语;why 和because 均可引导表语从句，其区别是：why 引导表语从句强调结果，because 引导表语从句强调原因。句中空格后文表明的是结果，故用why。
8. _______ we are doing has never been done before.
A. That
B. What
C. Which
D. Whether
【答案与解析】选B。what 在此引导主语从句且在从句作宾语，它相当于the thing that。
9. People have heard _______ the President has said; they are waiting to see _______ he will do.
A. how, how
B. what, what
C. when, how
D. that, what
【答案与解析】选B。两空均填what，均用于引导宾语从句，因为两个宾语从句中的动词said 和do 均缺宾语，而在各个选项中只有what 可用作宾语。
10. When you answer questions in a job interview, please remember the golden rule: Always give the monkey exactly _______ he wants.
A. what
B. which
C. when
D. that
【答案与解析】选A。what 引导宾语从句。由于动词wants 缺宾语，所以填what。句意是：当你找工作面试回答问题时，请记住这条黄金定律：永远给予对方确实想要的东西。
11. These wild flowers are so special that I would do _______ I can to save them.
A. whatever
B. that
C. which
D. whichever
【答案与解析】选A。I can to save them 为I can do to save them 之略，此句中的do 缺宾语，故选whatever。
12. _______ she was invited to the ball made her very happy.
A. What
B. That
C. When
D. Because
【答案与解析】选B。that 在此引导主语从句，无词义，也不充当句子成分。注意不要根据中文意思选D，因为because 不用于引导主语从句。
13. Eat ______ cake you like and leave the others for ______ comes in late.
A. any, who
B. every, whoever
C. whichever, whoever
D. either, whoever 【答案与解析】选C。两个空格处均为引导宾语从句的引导词，而四个选项中两者可引导宾语从句的只有C。
14. I had neither a raincoat nor an umbrella. _______ I got wet through.
A. It was the reason
B. That was why
C. There was why
D. That was because
【答案与解析】选B。比较That’s why…与That’s because…：前者用于强调结果，后者用于强调原因。如下面一题选D：
I got wet all through. _______ I had neither a raincoat nor an umbrella.
A. It’s the reason
B. That’s why
C. There’s why
D. That’s because
15. ____ has helped to save the drowning girl is worth praising.
A. Who
B. The one
C. Anyone
D. Whoever
【答案与解析】选D。由is worth praising 这一谓语可知前面是主语从句，排除不能引导从句的B 项和C 项;whoever 引导主语从句表示“任何……的人”，在此它相当于anyone who。
16. _______ medicine works in a human body is a question _______ not everyone can understand fully.
A. How; that
B. That; which
C. That; which
D. What; that 【答案与解析】选A。how 引导主语从句，that 引导定语从句。

定语从句易错题
1. The factory was built in a secret place, around ______ high mountains. A. which was B. it was C. which were D. them were 解析:最佳答案是C，around which were high mountains 是一个由"介词+which"引出的非限制性定语从句，而在该从句中，主语是high mountains，around which 是表语，所以句子谓语应用复数were，而不是用单数was. 请做以下类例题目（答案均为C）： （1）Yesterday we visited a modern hospital, around _______ some fruit shops. A. which is B. it is C. which are D. them are （2）The murder happened in an old building, beside ______ the city police station. A. which are B. it is C. which is D. them are （3）Next month we'll move to a new building, next to _______ a nice restaurant where we can have Chinese food. A. which are B. it is C. which is D. them are 2. A man with a bleeding hand hurried in and asked, "Is there a hospital around ______ I can get some medicine for my wounded hand?" A. that B. which C. where D. what 【解析】最佳答案为C。以上语法分析并不算错，但问题是，照此分析，此句的意思即为：有没有这样一个医院，我在它的附近可以买药治我的手伤？这样的语境显然有点不合情理，因为人们通常是在医院里面治伤，而不是在医院附近治伤。此题选 C 的理由是：句中的around 不是介词，而是副词，意为"在附近"；其后的where 引导定语从句用以修饰其前的地点名词hospital，句意为：附近有没有一家医院，我可以去治我的手伤？ 3. _____ is known to everybody, the moon travels round the earth once every month. A. It B. As C. That D. What 解析：最佳答案是B。as 引导的是一个非限制性定语从句。 4. _______ is known to everybody that the moon travels round the earth once every month. A. It B. As C. That D. What 解析：此题答案选A，it 为形式主语，真正的主语是后面的that 从句。
外研版英语中考英语名词性从句易错题集锦-名师教育含答案解析
外研版英语中考英语名词性从句易错题集锦-名师教育含答案解析 一、初中英语名词性从句 1．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。 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．Exactly _________ the potato was introduced into Europe is uncertain, but it was probably around 1565. A. whether B. when C. why D. 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。根据时间状语round 1565得知这里是指时间不确定。故选B。 【点评】考查名词性从句，本题涉及when引导的主语从句。 4．It matters little ______ a man dies, but _____ matters much is ______ he lives. A. how; what; how B. how; it; how C. why; it; why D. 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。

That; what B. That; that C. What; that D. What; what 【答案】 A 【解析】【分析】句意：众说周知，礼貌在每一个国家中都是非常重要的，但是麻烦是，不同的国家对于什么是良好的礼貌有着不同的认识。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 clear to the members of the committee is that the President will not give in to their demands.

英语定语从句易错题精选(1)
必备英语英语定语从句易错题精选 一、定语从句 1．The girl catches the flowers on a wedding will be the next to get married. A．whom B．which C．who D．whose 【答案】C 【解析】 考查定语从句的用法。Whom指人，作从句的宾语；which指物，作从句的主语或宾语；who指人，作从句的主语或宾语；whose即指人也指物，作从句的定语，后跟名词。根据动词“catches”可推断关系词作从句的主语，而“the girl”指人，故选C。 2．—Have you ever heard of Langlang? —Sure. He is one of ______ pianists ______ I have even seen. A．good; that B．much better; who C．the best; which D．the best; that 【答案】D 【解析】 【分析】 【详解】 句意：——你有没有听说朗朗？——当然听说了。他是我见过的最好的钢琴家之一。Good 好的，better更好的；best最好的。形容词的比较级前可用much修饰，表示程度；形容词的最高级前通常要加定冠词。one of……之一，其后面的中心名词用复数形式，该名词前的形容词用最高级形式。先行词pianists在宾语从句中作宾语，他的前面有最高级修饰，该用关系代词that代替。所以选D。 3．Xiandao Lake in Yangxin is the famous place ________ we'll visit next week. A．that B．who C．where D．whom 【答案】A 【解析】 试题分析：句意：阳新的仙岛湖是我们下周要参观的著名的地方。本句考查定语从句，先行词是place，从句意来看，其在定语从句中作visit的宾语，指事物，因此关系词用that。故选A。 考点：考查定语从句。 4．Yesterday Li Ming went to the village ______ his family lived ten years ago. A．when B．which C．where D．that

【英语】名词性从句易错题1 一、名词性从句 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．Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意：一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故选A。 【点评】考查名词性从句，本题涉及"特殊疑问词+ever"引导的主语从句。 3．_______ are playing an important part is well known to us all. A. That who B. Those who C. Who that D. Who 【答案】 D 【解析】【分析】考查主语从句。句意：谁起着重要作用，这是众所周知的。主语从句缺少引导词，从句缺少主语，故选D。 4．____ he will offer us enough help doesn't matter a lot to our success. A. If B. Whether C. Before D. How 【答案】 B 【解析】【分析】句意：他是否提供帮助对于我们的成功没有什么关系。If不可以引导主语从句，故选B。 【点评】考查名词性从句，本题涉及whether引导的主语从句的应用。 5．____ made me more unhappy was ___ the boy asked my friend to be his girlfriend and she agreed. A.
