七、名词性wh-从句

1)由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外,还可充当介词宾语、宾语补语和间接宾语等,例如:

主语:How the book will sell depends on its author. 书销售如何取决于作者本人。

直接宾语:In one's own home one can do what one likes. 在自己家里能够随心所欲。

间接宾语:The club will give whoever wins a prize.

俱乐部将给得胜者设奖。

表语:My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。

宾语补足语:She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。

同位语:I have no idea when he will return.

我不知道他什么时候回来。

形容词宾语:I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。

介词宾语:That depends on where we shall go.

那取决于我们去哪儿。

2)Wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末,例如:

It is not yet decided who will do that job.

还没决定谁做这项工作。

It remains unknown when they are going to get married. 他们何时结婚依然不明。

八、if, whether引导的名词从句

1)yes-no型疑问从句

从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,所以也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同,例如:主语:Whether the plan is feasible remains to be proved. 这个计划是否可行还有待证实。

宾语:Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。

表语:The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。

同位语:They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。

名词性从句的解题技巧(二)

名词性从句的解题技巧(二) 安徽省蚌埠二中----朱正军 B)名词性从句缺表语: 从句缺表语比上述情况复杂一些,根据句意分析,如果需要使用连接代词的话,判断选择的 方法与上述方法相同,而表达“谁的?”这一所属关系时则用whose (如:I don’t know whose this book is.)。如: 15. I read about it in some book or other. Does it matter ____ it was? 【北京卷2006】 A. were B. what C. how D. which 16. ----Can you do me a favor? ----It depends on ____ it is. 【北京卷2006】 A. which B. whichever C. what D. whatever 17. I want to be liked and loved for _____ I am inside. 【北京卷2010】 A. who B. where C. what D. how 18. Engines are to machines ____ hearts are to animals. 【山东卷2006】 A. as B. that C. what D. which 【这是一个较为特殊的句式结构,从句是第一个are的表语。句意为“发动机对于机器而言就 如同动物的心脏。”】 答案:15. D 16. C 17. C 18. C。选择方法上文已经讲过,在此不再赘述。 如果不能使用连接代词,则根据语义选择适当的连接副词,如Please tell me who/what/where/how he is一句中的几个连接词都是正确的,具体用哪一个要看上下文。 C)名词性从句缺定语: 名词性从句缺定语如果指“谁的?”则用whose,如:I don’t know whose book this is. 如果指“什么的?”则用what或whatever,如:I don’t care what person you’d like to make friends with.或You can make friends with whatever person you like. 再如: 19. It is uncertain_____ side effect the medicine will bring about although about two thousand patients have taken it. 【浙江卷2010】 A. that B. what C. how D. whether 该题表达的是“什么样的”,所以答案为B。 如果指“哪一个?”则用which或whichever。如: 20. ____ team wins on Saturday will go through to the national championships. 【山东卷2006】 A. No matter what B. No matter which C. whatever D. whichever 【谈及星期六的比赛,当然就有了范围的限制,所以要用which或whichever,意为“哪个队”,分析一下句型结构不难看出连接词既是team的定语,whichever team又是will go through的 主语,即“一身兼两职”。同时,No matter wh+只能引导让步状语从句。】 答案:20. D。which与whichever之间语法上的区别和who与whoever whom与whomever相同,whichever可解释为any person who/any thing which。 二)如果名词性从句中不缺少上述成分,则根据句意有无疑问将连接词的选择分成两种情况:A)从句语义是确定无疑的: a) 从句表达的是“一种事实”则用that。 1. It never occurred to me ____ you could succeed in persuading him to change. 【陕西卷2010】 A. which B. what C. that D. if

专题11 名词性从句.ppt.Convertor

专题十一名词性从句 一、定义 在复合句中起名词作用的句子叫名词性从句(Noun Clauses)。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词性从句又可分别称为主语从句(the Subject Clause)、宾语从句(the Object Clause)、表语从句(the Predicative Clause)和同位语从句(the Appositive Clause)。 二、引导名词性从句的连接词 引导名词性从句的连接词可分为三类: 1. 从属连词:that, whether/if, as if 2. 连接代词:what, which, who, whom, whose 3. 连接副词:when, where, why, how 具体用法见下表:

分 有 可 略。

【考点一】考查名词性从句的引导词 在高考单项选择题中,名词性从句连词的选择往往是测试的

热点。考生若不认真分析,没有正确的解题方法,常常造成判断上的失误,最终错选了连词。

名词性从句引导词的用法: 1. who意为“谁”,在从句中作主语。 2. whom意为“谁”,在从句中作宾语,但在口语中常用who 代替whom。 3. whoever(=anyone who)意为“凡是……的人”,它的宾格形式是whomever (但在口语中常用whoever代替whomever)。 4. whose意为“谁的”,在从句中作定语。 5. what (=the+n.+that)意为“什么”;whatever(=anything+that)意为“凡是……的物”。what 和whatever都可在从句中作主语、表语、宾语。 6. which意为“哪一个;哪些”;whichever意为“无论哪一个都”。which 和whichever都可在从句中作主语、宾语、表语。 7. where意为“在哪儿”,在从句中作地点状语;when意为“什么时候”,在从句中作时间状语;how意为“如何”,在从句中作方式状语;why意为“为什么”,在从句中作原因状语。 8. whether意为“是否”,在从句中不充当任何语法成分;引导及物动词的宾语从句时,可与if互换;引导介词的宾语从句或引导主语、表语、同位语从句时,只用whether。

(完整版)高考英语【名词性从句】

专题十名词性从句 第一节基本知识与基本概念 【什么是名词性从句?】 顾名思义,主语从句在句子中作主语。有时本身出现在主语的位置上,也有时出于句子结构的考虑退到句子的尾部,前面用形式主语it代替。从句作主语时,谓语动词一般为单数形式。如: What I saw was beyond any verbal description. That his hair was turning grey worried him a bit. Why the company denied the contract is still unknown. When and where the government will build a city square is under discussion. It is pretty annoying that a small part of the machine is missing. It remains to be seen whether the new novel will be well received. 【宾语从句】 在句子中作宾语的从句就是宾语从句。由于这是同学们接触比较早的一种从句,应该问题不大。所以在近年的高考题中,以宾语从句的知识作为考点的题目较少。但是,宾语从句也有自己的特殊情况,如介词的宾语,形容词的宾语,宾语从句提前和并列的宾语从句等现象。如: We assumed that there would be more than 100 guests. He told the police in detail what he saw and heard. Nobody is sure what humans will look like in a million years. That will depend on whether they can get the chance. Whether I will have the time I am not sure at the moment. The conductor complained that we were not gifted in singing and that he would never come again. 【表语从句】 表语从句的最重要脸谱就是它们应该出现在系动词的后面。如: The only question left is how often the workers are paid. His idea for the coming weekend is that we go skating. 【同位语从句】 从脸谱上看,同位语从句最为麻烦。因为它们也是出现在一个名词的后面,起着解释说明的作用。
