【英语】英语名词性从句题20套(带答案)
【英语】英语名词性从句题20套(带答案)一、初中英语名词性从句1．________ his failure lies is expected ________ clear to us.A. What… to makeB. How… madeC. Where… to be madeD. Why… making【答案】C【解析】【分析】句意：他的失败之处有可能被我们弄清楚。

make sth. clear to sb为固定搭配，意为“向某人阐明某事，使某人弄清某事”。

初中英语名词性从句练习题(附答案解析)
初中英语名词性从句练习题（附答案解析）一、单选题1．Do you know ________________________?A．how many populations there are in the worldB．how much population there is in the worldC．how many the population of the world isD．what the population of the world is1．答案D解析句意：你知道世界人口是多少吗？分析句子可知，句中population表示“世界人口”时，指某一国家或地区的人口时，谓语动词要用单数is，且在对人口的数量进行提问时，只能说What's the population，而不能用how many和how much 修饰，因为这里的population相当于the number of people，所以在提问时要使用疑问词what。
故选D。
点评考查名词性从句，本题涉及what引导的宾语从句。
2．—Could you tell me________?—At nine o'clock, in ten minutes.A．how will he leave B．when he left C．when he is leaving2．答案C解析句意：——你能告诉我他什么时候走吗？——九点，十分钟后。
根据“ in ten minutes.”十分钟后，可知询问的是时间，应用when引导，且表将来，应用现在进行时，故选C。
点评考查名词性从句和时态，本题涉及when引导的宾语从句和现在进行时表将来。
3．You can't imagine ___ when I get a cell phone for my birthday.A．how I was excited B．how excited I wasC．how excited was I D．I was how excited3．答案B解析句意：你无法想象当我生日得到一部手机时我有多兴奋。

【英语】名词性从句试题和答案一、名词性从句1．—What impresses you most when you visit the Acropolis ?— ________ it is that has brought the grand palace into today's terrible scene.A. WhereB. WhatC. HowD. When【答案】 B【解析】【分析】句意：——当你参观雅典卫城时，你印象最深的是什么？——使我印象最深的是什么将从前宏伟的宫殿变成了今天惨不忍睹的样子。
强调句型的特殊疑问句式：疑问词（如what） is it that+其它，本句强调的是什么使得从前宏伟的宫殿蜕变的，所以用表示内容的what，选B【点评】考查主语从句和强调句，本题强调主语从句的引导词。
2． is clear to the members of the committee is that the President will not give in to their demands.A. WhoB. ItC. AsD. What【答案】 D【解析】【分析】句意：委员会成员清楚的是，总统不会向他们的要求让步。
that the President will not give in to their demands.这个句子作表语； is clear to the members of the committee这是主语从句，这里缺少主语从句的连接词，并且连接词在句中作主语，it是代词，不是了；连接词，故排除B；as作主语时，是在定语从句中，故排除C；who指人，根据表语指的事情，不是人，故排除A；what在主语从句中可以作主语或宾语，指事，符合句意，故选D。
【点评】考查名词性从句，本题涉及what引导的主语从句。
3．_______ are playing an important part is well known to us all.A. That whoB. Those whoC. Who thatD. 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．--- 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。
5．—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; thatB. it; thatC. it; becauseD. 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。
6．They lost their way in the forest, and ___ made matters worse was that night began to fall.A. itB. whichC. thatD. 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。
7．It is a rule in his family that _______ comes home first should cook the dinner.A. anybodyB. whoC. whoeverD. who that【答案】 C【解析】【分析】句意：在他的家里有个规定，就是先到家的人要先做饭。
whoever 有两个词义：1no matter who，在这种用法时引导一个让步状语从句；2anybody that，在这种用法时，它连接一个名词性从句，在本题中它连接的是主语从句。
这里就是第二个用法。
所以选C。
8．________ the weather will not clear up until next week is bad news for us.A. AsB. IfC. WhetherD. That【答案】 D【解析】【分析】考查主语从句。
句意：直到下周天气才放晴，这对我们来说是坏消息。
此处是that引导的主语从句，that无实义，只其引导作用，故答案为D。
【点评】主语从句属于名词性从句，在名词性从句中，that无实义，只起连接作用，不做句子成分；if/whether起连接作用，不做句子成分，有实义“是否”。
做题时注意看从句是否少成分。
9．______ is our belief that improvements in health care will lead to a stronger, more prosperous economy.A. WhichB. WhatC. ItD. As【答案】 C【解析】【分析】句意：医疗保健的进步将促进一个更强大、更繁荣的经济，这是我们的信念。
that引导的是主语从句，故空格处应该用it作形式主语，代替真正的that引导的主语从句。
故答案选C。
【点评】考查it的用法，以及主语从句的应用。
10．They lost their way in the forest, and ________ made matters worse was that night began to fall.A. thatB. itC. whatD. which【答案】 C【解析】【分析】句意：他们在森林里迷路了，更糟糕的是天开始黑了。
根据连词and可知，本句需要一个引导主语从句的连接词，该词同时还要能在从句里充当主语。
that不能在句中作成分；it不能引导主语从句；which意为“哪一个”，不符合本句语境。
排除A、B、D三项。
故选C。
【点评】考查名词性从句，本题涉及what引导的主语从句的应用。
11．________ has been proved is that animals and insects have their own languages.A. WhatB. AsC. ItD. That【答案】 A【解析】【分析】句意：已被证明的是动物和昆虫有自己的语言。
根据is判断，此处为主语从句，分析该从句，缺少主语，用what。
选A。
【点评】考查名词性从句，本题涉及what引导的主语从句的应用。
12．They lost their way in the forest, and ________ made matters worse was that night began to fall.A. itB. whichC. thatD. what【答案】 D【解析】【分析】句意：他们在森林里迷路了，情况更糟糕的是天又黑了。
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。
故选D。
【点评】考查名词性从句，本题涉及what引导的主语从句的应用。
