1、名词性从句九大高考热点分析名词性从句包括主语从句、宾语从句、表语从句和同位语从句。因为它是从句，因此具有句子的结构特点（即有一套主谓成份）；同时又具有名词性特点，所以可以在复合句中作主语、宾语、表语或同位语。名词性从句是中学英语学习的重点，也是高考的主要考点之一。我们必须弄懂和掌握以下热点问题。一、连接词what与that的用法区别。引导主、宾、表语从句时，what要充当主语、宾语或表语等句子成分，that不作任何成分，只在语法上起连接的作用。例如_ we cant get seems better than _ we have.A. What; what B. what; that C. T

2、hat; that D. That; what解析：本句包含一个主语从句和一个宾语从句，且两个从句都缺乏宾语，可见两个引导词都必须充当成分，所以答案是A。又如：_ caused the accident is still a complete mystery.A. What B. That C. How D. Where解析：该题答案是A，what在主语从句中作主语，即作谓语动词caused的执行者。在下面的例句中，that不充当任何成份，只起语法连接作用（因为句子本身不缺成分）： That the former Iraq president Saddam was captured has b

3、een proved.二、 连接词whether和if的用法区别。通常，引导主语从句、表语从句和引导同位语从句时，要用连词whether，不用if；习惯上也只能说whether or not，而不说if or not。例如：_ the 2000 Olympic Games will be held in Beijing is not known yet.A. Whenever B. If C. Whether D. That解析：试题中的从句位于句首，不难知道这是一个主语从句，所以答案是C。但是在宾语从句中表达“是否”既可用if也可用whether。三、 名词性从句的语序。与别的从句一样，名词

4、性从句必须用陈述语序。例如:No one can be sure _ in a million years.A. what man will look like B. what will man look like C. man will look like what D. what look will man like解析：由于从句不能倒装，所以答案只能是A。又如：You cant imagine _ when they received these nice Christmas presents.A. how they were excited B. how excited they we

5、reC. how excited were they D. they were how excited 解析：答案是B。同时还须注意，从句的引导词必须始终置于句首，而且how和被修饰的词excited不能分裂开。四、 形式主语、形式宾语。当主语从句较长，而谓语较短时，常常将从句后置，而用it作为形式主语，置于句首。动词后接复合宾语，也可用it作形式宾语。例如:_ is a fact that English is being accepted as an international language. A. There B. This C. That D. It解析：所需词至于句首，同时后面有

6、that-从句（逻辑主语），可见这里应该用形式主语it,所以答案是D。think, find, consider, believe, feel等动词后常带复合宾语。例如：Many people think it possible that a trade war between EU and the States will happen.五、 Who / whoever, what / whatever等的用法区别。一般说来，what/who等含特指意义，而whatever/whoever等含泛指意义，意为“无论什么/无论谁”。例如：It is generally considered unw

7、ise to give a child _ he or she wants.A. however B. whatever C. whichever D. whenever解析：答案是B，whatever引导一个宾语从句，并且作wants的宾语。这里的whatever不能改成what，因为题意想表达的显然是“无论孩子要什么就给他/她什么事不明智的”，具有泛指的概念。同时要注意，这里whatever也不能改用no matter what，因为后者只能引导状语从句。又如：_ has helped to save the drowning girl is worth praising.A. Who B

8、. The one C. Anyone D. Whoever解析：答案是D，whoever意为“无论谁”，表泛指。比较下例：I cant remember at the moment who has said the words. （这里的who表特定的某人）六、 Where, when, why等连接副词引导的名词性从句。Where, when, why等连接副词也可以引导名词性从句，使用的关键是：这个词必须符合句子的逻辑意义要求。例如： I drove to Zhuhai for the air show last week. Is that _ you had a few days of

9、f?A. why B. when C. that D. where 解析：答案是A，why引导的从句作表语，同时why在从句中作原因状语。这里之所以选why，而不是when或 where等，唯一的依据便是句子的逻辑含义，及语境。又如（MET94）；Do you remember _ he came?Yes, I do, he came by car.A. How B. when C. that D. if解析：答案是A，从答语 “he came by car”可知这里问的是“he”来的方式，所以用how引导。七“介词+who(m)引导的宾语从句”与“介词+ whom”引导的定语从句的区别。介词

10、后面的引导词用主格还是宾格，决定于它在宾语从句中作主语还是宾语。例如：It was a matter of _ would take the position.A. who B. whoever C. whom D. whomever解析：答案是A。这是一个含宾语从句的复合句，作介词of宾语的，是后面的整个句子，而不是宾语从句的引导词，由于这里引导词在从句中作主语，所以要用主格who（作宾语时自然要用whom）。比较下例：Our country has thousands of excellent scientists, most of whom have received higher ed

11、ucation at home.这是一个“介词+关系代词”引导的定语从句；引导定语从句的是“most of+关系代词”而不只是这个关系代词，同时这个引导词又作介词of的宾语，所以要用宾格whom。（注意与介词后面的宾语从句的引导词的用法进行比较和区别。）八、连接词that的省略。引导宾语从句时，that通常可以省略，但引导主语、表语和同位语从句时，that不能省。例如：Chinas success in manned-spacecraft travel shows _ our country has become one of the greatest powers in space rese

12、arch. A. what B. which C. 不填 D. it that解析：该句中的从句作shows的宾语，是宾语从句，又因为从句中不缺主、宾语，所以只能用that引导；又因引导宾语从句时that可以省略，所以答案是C。九、同位语从句引导词where, when的用法特点。说明先行词内容的同位语从句的引导词where, when与被说明的名词在概念上不一致。但引导定语从句的引导词却必须保持一致。是比较：Then arose the question _ we were to get so much money.This the house _ the great man Mao Zed

13、ong was born 110 years ago.A. where B. that C. about which D. in which解析：答案分别是(1) A (2) A/D。先行词与where, when概念一致时，是定语从句，（2）中的house与where同表地点，且这个关系副词where或when可以用“介词+which”的形式代替，所以答案A 和D都可以引导。（1）题中的question与where不表同一概念，可见是同位语从句，所以where不能改用“介词+which”的形式。2004-07年高考题1.(07全国17)matters most in learning Eng

14、lish is enough practice.A.WhatB.WhyC.WhereD.Which答案 A解析 本题考查主语从句，且从句中缺少主语，所以A项正确。2.(07天津15)The seaside here draws a lot of tourists every summer.Warm sunshine andsoft sands makeit is.A.whatB.whichC.howD.where答案 A解析 句意为：每年夏天这儿的海边都吸引大量的游客。温暖的阳光和柔软的沙滩使海边成了现在的样子。what引导宾语从句，且what在从句中作表语，意为“的（东西）”。3.(07安徽

16、s bedroom.A.whyB.thatC.whenD.where答案 B解析 句意为：确保门关上了，且所有的灯都关上了之后，那个男孩打开门进了他的卧室。checked后跟了两个宾语从句，第一个从句的引导词that省略了。5.(07陕西8)parents say and do has a life-long effect on their children.A.ThatB.WhichC.WhatD.As答案 C解析 本题考查名词性从句的选用。分析句子结构可知，此处主语从句缺少动词say and do的宾语，故用what。6.(07浙江5)Why not try your luck downt

It depends onit is.A.whichB.whicheverC.whatD.whateve

20、r答案 C解析 疑问词+ever引导让步状语从句或名词性从句，但句意为：要看帮什么忙了。所以whatever不合适。12.(06天津4)What we used to thinkimpossible now does seem possible.A.isB.wasC.has beenD.will be答案 B解析 由句意“我们以前认为不可能的事现在看起来的确是可能的”和谓语动词used to think可知空格处的谓语部分应该表达过去意义。13.(06山东27)team wins on Saturday will go through to the national championships

21、.A.No matter whatB.No matter whichC.WhateverD.Whichever答案 D解析 由句式结构可知此空白处应选择连词引导主语从句，且在主语从句中作team的定语使用，选项中只有whichever和whichever可同时具备这两种功能，且从数个已知的队中选择一个，故选whichever。14.

That waswe did this morning.A.whenB.whichC.whereD.what答案 D解析 本题考查了表语从句的用法。由句中句子结构可知，此处缺一表语从句引导词，而且要在句中作did的宾语，故只有what符合要求。17.(06全国16)What did your parents think about your decision?They always let me doI think I should.A.whenB.thatC.howD.what答案 D解析 what可以在宾语从句中作主语、宾语或表语。在本题中作动词

29、en forced to give up her job.A.when;howB.how;when C.how;howD.why;why答案 C解析 本题考查的是动词explain后引导的宾语从句的引导词的选用。第一空用how较易，但第二空很多考生填when，其实在前一分句中已有时间状语，故此处用when明显不对，仍然需用how引导，即“她是如何被迫放弃工作的”。26.(05山东26)The shopkeeper did not want to sell forhe thought was not enough.A.whereB.howC.whatD.which答案 C解析 what引导从句作
