名词性从句试题和答案经典
一、名词性从句
1．He took a trip to Beijing last week and ________ he saw at the Forbidden City impresd him deeply.
A. that B. how C. what D. which
【答案】 C
【解析】【分析】句意：上周他到北京旅行了，他在故宫所看到的给他留下了深刻的印象。分析句子结构可知，连词and后为一个名词性从句，因此应该使用what引导，且what在从句中作主语，故选C。
【点评】考查名词性从句，本题涉及what引导的主语从句。
2．___ surprid me most was ____the girl pasd 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。 ___ surprid me most 是一个主语从句，从句中缺少主语，故填what； ____the girl pasd 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。
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; who B. It; who C. As; whom D. 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．_______ are playing an important part is well known to us all.
A. That who B. Tho 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。
5．Has it been announced ______?
A. when are the planes to take off B. that are the planes to take off
C. where are the planes to take off D. when the planes are to take off
【答案】 D
【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。
【点评】考查名词性从句，it作形式主语，关系副词when引导的从句作真正的主语。
6．--- made her ashamed of herlf?
--- the lowest mark in her class.
A. What; Becau 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becau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．—Tell me something about your adventure in the rainforest, plea.
— We lost our way in the forest and ___ made matters wor was ___ night began to fall.
A. what; that B. it; that C. it; becau D. what; becau
【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 wor 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 wor，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. anybody B. who C. whoever D. 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。
10．________ we may find interesting is that it usually takes more to be polite.
A. That B. What C. Which D. /
【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。此处是主语从句做主语，从句没有引导词，缺少宾语，故答案为B。
【点评】考查名词性从句，本题涉及what引导的主语从句的应用。
