1、Section Grammar&Writing语法 专项突破写作 能力提升名词性从句:宾语从句和表语从句指出黑体单词引导何种从句,以及在句中作的成分。1It is Henry Adams,an American businessman,who is lost inLondon and does not know what he should do.(宾语从句;作宾语)2May we ask what youre doing in this country and what yourplans are?(宾语从句;作表语)3I cant say that I have any plans.(宾语

3、xplain how this happened?(宾语从句;作状语)一、基础点拨(一)名词性从句1定义:在主从复合句中,相当于名词的从句称之为名词性从句。名词性从句在句中的功能相当于名词。它包含主语从句、宾语从句、表语从句及同位语从句。2名词性从句的关联词及其在句中的功能:分类关联词意 义功 能连接词that无意义不充当成分whether/if是否不充当成分连接代词who(ever)(无论)谁主语、宾语、表语whose谁的定语what(ever)(无论)什么主语、宾语、表语、定语which(ever)(无论)哪一个主语、宾语、定语分类关联词意 义功 能连接副词when(ever)(无论)何时

4、时间状语where(ver)(无论)哪里地点状语why为什么原因状语how(ever)(无论)如何/怎么方式状语(二)宾语从句1定义:在主从复合句中充当宾语的从句,其作用相当于一个名词。它可以作谓语动词的宾语,也可以作非谓语动词、某些介词等的宾语。I dont know where they have gone to spend their holidays.我不知道他们去哪里度假了。2由连接词that引导的宾语从句。that在从句中不担当任何成分,在口语或非正式的文体中常被省去。We have decided(that)we would go there by bus.我们已决定乘公共汽车去

5、那里。3whether/if引导的宾语从句。whether/if在从句中不充当成分,但是有“是否”之意,从句要用陈述语序。I dont know whether/if he is ill.我不知道他是否病了。点津 whether/if引导的宾语从句在作ask,care,find out,know,wonder等动词的宾语时,带有疑问意义。此时whether与if可互换。4连接代词及连接副词引导的宾语从句。连接代词及连接副词引导的宾语从句相当于特殊疑问句,连接词都在从句中担当一定的成分。I dont know what I should do next.(what引导宾语从句,并在从句中作宾语)

6、我不知道下一步做什么。I wonder who will play in the basketball match.(who引导宾语从句,并在从句中作主语)我不知道这场篮球赛谁会上场。Ask him which he wants,the big one or the small one.(which引导宾语从句,并在从句中作宾语)问问他想要哪一个,大的还是小的。You can choose whatever you like.(whatever引导宾语从句,并在从句中作宾语)你可以选择任何你喜欢的。I dont know where we should start.(where引导宾语从句,并

8、从句。(3)两种形式在引导让步状语从句时可互换。Whatever you want to do(No matter what you want to do),your parents will always support you.(whatever引导让步状语从句,并在从句中作宾语)不管你想做什么,你的父母将永远支持你。(三)表语从句1定义:在主从复合句中充当表语的从句,其作用相当于一个名词。表语从句放在系动词之后,即主语系动词表语。This is where I dont agree with you.(where引导表语从句,where在从句中作地点状语)这就是我不同意你的地方。That

9、 is why he was late for class again.(why引导表语从句,why在从句中作原因状语)那就是他又一次上课迟到的原因。My question is where we will travel and how we will get there.(where引导表语从句,where在从句中作地点状语;how引导表语从句,how在从句中作方式状语)我的问题是我们将去哪里旅行并且我们将如何到达那里。2连接词that引导表语从句,不充当成分,无意义,但是不能省略。My advice is that we should get there by train.(that引导表

11、第一个that可省,但第二个that不可省)他们告诉我们那天下午会有一个会议,并且我们都应该参加这个会议。(2)在demand,order,suggest,insist,propose,advise,desire等表示要求、命令、建议、坚持等意义的动词后,that宾语从句中谓语常用“(should)动词原形”,表示虚拟。The policeman demanded that the gate(should)be shut.警察命令把大门关上。巧学助记口诀巧记后面常用虚拟形式的动词一坚持:insist二命令:order,command三建议:suggest,propose,advise四要求:d

12、esire,demand,require,request(3)动词it形容词或惯用搭配that从句,it为形式宾语,that从句为真正的宾语。I think it a pity that you could not come.(it为形式宾语,that引导的从句为真正的宾语)你不能来,我深深惋惜。(4)动词doubt用于否定结构或疑问结构时,接that从句作宾语。We dont doubt that he can do a good job of it.(doubt用于否定句)我们不怀疑(相信)他能把这件事做得很好。(5)主 句 为 第 一 人 称,主 句 谓 语 为 think,believ

14、whether与or或or not连用时,不可用if替换。She doesnt know whether she should get married now orwait.(whether.or.)她不知道是现在就结婚还是等等再说。(3)动词doubt用于肯定句式,其宾语从句用whether引导。I doubt very much whether he is coming.(doubt用于肯定句)我很怀疑他是否要来。(二)特殊的表语从句1as,as if/though引导的表语从句常置于系动词seem,appear,look,taste,sound,feel等之后。It looks as i

15、f a storm would come soon.(as if引导表语从句)暴风雨好像快要来啦。2句子主语为the reason时,表语从句通常用that引导,即构成句型:The reason why.is that.;The reason for.is that.意为“的原因是”。The reason why he asked for two days leave is that he had to takecare of his sick son.他请了两天假的原因是他要照顾他生病的儿子。3because可引导表语从句,常用于结构:This/That is because.意为“这/那是

16、因为”。Thats because I was too busy then.(强调原因)那是因为那时我太忙。易混辨析Thats because.意为“那是因为”,强调原因Thats why.意为“那是的原因”,强调结果Thats why we didnt attend that meeting.(强调结果)那就是我们为什么没有参加会议的原因。4 主 语 为 advice,suggestion,proposal,demand,desire,requirement,request,order,command等表示建议、要求、命令等意义的名词时,表语从句的谓语要用“shoulddo”,其中shoul

17、d可省,表示虚拟。His request is that they(should)stay here for the night.他请求他们应该在这儿逗留一晚。点津(1)从句语序要用陈述语序。(2)主句与从句的时态要保持一致(若为客观真理、科学原理、自然现象,则从句仍用一般现在时态)。They wanted to know where they could find this kind of plants.他们想知道到哪里能够找到这种植物。Last night,Dad tried his best to explain to his little child how theearth move
