【英语】名词性从句练习题(含答案)经典一、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。
分析句子可知，主语从句中的lie为不及物动词，所以主句中缺少状语，因此填where。
expect sth.to do.固定短语，“期望某事发生”，sth. be expected to do.意为”某事有可能发生“。
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”。
本句中make的宾语是where his failure lies 是被弄清楚，要用动词不定式的被动形式。
因此选C。
【点评】考查名词性从句及固定搭配，本题涉及主语从句和固定短语expect sth.to do.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．________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties.A. As; whoseB. It; whoseC. As; whomD. 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it is known to us all that…和whom引导的限制性定语从句。
4．It________that the road will be closed tomorrow for repairs.A. was announcedB. has been announcedC. had been announcedD. would be announced【答案】 B【解析】【分析】本题考查动词的时态和语态。
题干句子中that到句子结束是宾语从句，且从句动词用“will＋动词原形”表示将来，由此推断出空白处谓语动词应用现在的某种时态，在所给四个选项中，只有B项正确。
【点评】考查现在完成时的被动语态，其结构是have/has +been +done。
需要注意宾语从句的时态。
主句用现在时，从句所需的任何时态。

故选C。
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; 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。
8．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。
9．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。

根据句意可知，句子主语是一个主语从句，引导词即起引导作用又要做从句的一个成分，所以第一空填What；第二空是that引导的表语从句，只起引导作用，故选B。
【点评】考查名词性从句，本题涉及关系代词what引导的主语从句和表语从句的应用。
11．________ we may find interesting is that it usually takes more to be polite.A. ThatB. WhatC. WhichD. /【答案】 B【解析】【分析】句意：我们可能会发现有趣的是通常需要更多的礼貌。

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。
13．It matters little ______ a man dies, but _____ matters much is ______ he lives.A. how; what; howB. how; it; howC. why; it; whyD. 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。
【点评】考查名词性从句，本题涉及主语从句和表语从句的应用。
14．It was he said disappointed me.A. that; whatB. what; thatC. that; whichD. which; that【答案】 B【解析】【分析】句意：正是他说的话让我很失望。
这是一个强调句型,"it is/was that..."是固定搭配,"what he said"是被强调部分, 你可以发现去掉"it was that"后, 句子仍然完整。
"what he said"做主语,主语从句中"said"缺宾语用what补足，故选B。
【点评】考查主语从句的强调形式。
15．_______ is troubling me is ______ I don't understand ________ he saidA. What; that; whatB. What; what; whatC. That; that; whatD. Why; that; which 【答案】 A【解析】【分析】句意：我烦恼的是我不明白他说的话。
第一空是主语从句，从句中缺主语，要用What；第二空是表语从句，从句不缺成分，所以要填that；第三空是宾语从句，从句中的动词understand缺宾语，要填what。
