2013年名词性从句十三大高考热点分析 【考纲解读】 前几年高考主要考查宾语从句中用陈述语序以及连接词的选择等问题;近几年对名词性从句的考查趋于复杂灵活,往往把它与定语从句和状语从句的知识点放在一起考查,对名词性从句的考查主要有语序问题、时态的呼应问题和连接词的选择。有时候,会结合插入语或名词与同位语隔开,或使句子结构复杂化等使得难度增加。2011年全国卷及地方卷对名词性从句的考查占了较大比例,有18道考查到该部分,2012年考查的比例更大,有20道题考查了名词性从句的用法,可见对名词性从句的重视程度。在单项选择题中,近几年题干语境越来越丰富,句子结构也越来越复杂,其中名词性从句所引起的句子结构的复杂化占了较大比例,命题人侧重于对复杂句子结构的考查,是因为能否分析复杂句子结构是掌握英语语言的重要能力之一,所以在今年的高考题对名词性从句的考查还会倍加青睐。 从考生的角度来说,如果考生对句子结构掌握不过硬,对某些词或词组的用法不了解,就会容易造成和定语从句、状语从句的混淆,造成根本环节的误判而用其他从句的规则去解题。造成丢分。备考复习的过程中应该: 1.从结构和句意两方面分析定语从句和名词性从句,尤其是定语从句和同位语从句的区别。 2.从结构入手,分析名词性从句和状语从句之间的关系及区别。 3.加强名词性从句引导词各自意义,用法,特点的辨析。 4.加强长、难句的分析和理解练习

【考点一:语序问题】 名词性从句的语序问题一直断断续续地在各地高考题目中出现,由此可见其重要性。其实说来非常简单易记:永远陈述语气。即名词性从句中不会出现助动词提前的现象。如: 1.Who he is doesn’t matter much. 2.When and where we shall have the sports meeting is a question. 3.I don’t know what his name is. 4.I don’t know what is wrong with him. = I don’t know what is the matter with him. 5.You can’t imagine how excited I was at that time. 6.Can you tell me what size shoes you wear? Eg:1.No one can be sure ______ in a million years. (MET1991) A. what will man look like B. what man will look like C. man will look like what D. what look will man like 答案:B。这个题就是典型的考查宾语从句的语序问题。根据以上所述,应该是陈述语序。所以A、C两个选项就不可能了。而D选项明显不符合我们的语言习惯。

Eg:2.You can’t imagine ____ when they received these nice Christmas presents.

A. how they were excited B. how excited they were C. 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。

Eg:3. “Is Mary from New York City” “I don't know _______.” A. from what city does she come from B. from what city she come C. what city does she come from D. what city she comes from

【考点二:that和what的区别问题】 能引导名词性从句的关系代词有who, whom, what, whose, which, whichever, whatever, whoever八个。为何单独讲what的用法呢?重要!在考试中出现的频率高!在《定语从句》中,我们提到过,what是不能引导定语从句的。定语从句中如果缺少的成分是主语、宾语、表语,我们选择的是关系代词that或其他。现在山头换了,到了名词性从句的知识范围了。What在名词性从句中就很有用武之地了。还是分析成分,what 在从句中作的主语、宾语、表语。而that只是一个“连接词”,既不作什么成分,也没有什么意义。如: 1.What you did doesn’t agree with what you promised. 2.What he couldn’t understand was why his teacher was never satisfied with him. 3.The matter of salary is what I care most if I decide to change my profession. 4.What we can’t get always seems better than what we have already got. 5.I think that your composition is no better than his. 6.That you don’t love her is not my business.

Eg:1.____ we can’t get seems better than ____ we have. A. What; what B. what; that C. That; 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。 Eg:2. His success was because of ________ he had been working hard. A. that B. the fact which C. the fact that D. the fact 【考点三:that和whether的区别问题】 有时候,它们两个比较难以区别,因为,它们都是连接词,都在从句中不作成分。但是,它们之间最大的区别在于“意义”。即that在从句中既不作成分,也没有自己的意义;而whether就不同了。它虽然不在从句中作什么成分,但是它又意义,即“是否”。这就能够左右从句的意思,使从句所表达的意思变成一个还没有确定的因素。如: 1.I don’t know whether he can join us or not. 2.I’m sure that he can join us. 3.It is none of your business whether I love her. 4.It is none of your business that I don’t love her. 综上所述,区分that还是whether,重要一点就是看主句需要从句表达一个什么意思,是确定的,还是不确定的;是事实还是疑问。前者选that,后者选whether。如: Eg:1.I have no doubt _____ Mr. Johnson will make it here on time. A. that B. whether C. why D. when 答案:A。这个题之所以选择that,就是因为前面的I have no doubt(毫无疑问),这样 的主句已经不再需要从句表达什么“是否”了。 Eg:2.No one can be sure _____ the board will accept our conditions. A. that B. whether C. why D. what 答案:B。 这个题中的No one can be sure(没有人能肯定)就要求从句表达一个“董 事会能否接受我们的条件”的意思,而不能是一个既定的事实。 【考点四:if和whether的区别问题】 二者在引导宾语从句时都有“是否”之意。但并不是永远可以互换。一般认为,二者可 以互换的环境也只有在宾语从句中。1、 在动词不定式之前只能用whether 。如: 例8 I can’t decide whether to stay. 我不能决定是否留下。 2、 在whether …… or not 的固定搭配中。如: 例9 I want to know whether it’s good news or not . 我想知道是否是好消息。 3 、在介词后,只能用whether。如: 例10 His father is worried about whether he lose his work . 他的父亲担心是否会失去工作。 4、宾语从句放在句首表示强调时,只能用whether 。如: Whether this is true or not, I really don’t know. 这是否真的,我真的不知道。 (例11 Whether they can finish the work on time is still a problem . 他们是否能准时完成这项工作还是个问题。--此例为主语从句,有误,感谢指出) 5、用if会引起歧义时,只用whether。如: 例12 Could you tell me if you know the answer ? 这句话有两种意思:“你能告诉我是否知道答案吗?”或“如果你知道答案,请告诉我,好吗?”。如用whether可避免歧义. 二者在引导宾语从句时都有“是否”之意。但并不是永远可以互换。一般认为,二者可 以互换的环境也只有在宾语从句中如: He didn’t give us explicit reply whether/if he will attend our wedding ceremony. 1. _______ we’ll go camping tomorrow depends on the weather. (1996) A. If B. Whether C. That D. Where 答案:B。这是主语从句。
