C 该题是考查宾语从句中形式宾语的用法。在enjoy, hate, like, love等表示“喜怒哀乐”的词和take等此后若跟宾语从句需用形式宾语it,把真正的宾语放后。题意:我喜欢秋天晴朗明亮的天气。又如:I hate _ when people talk with their mouths full(xx) A it Bthat Cthose Dthem2. B 该题是考查名词性从句中的表语从句的用法。据题意:你一直说人人平等,这就是我不能苟同之处。此处是指的everyone should be equal这句话这一点,我不能苟同。故选where。3. A 该题根据交际情景考查名词性从句的用法。根据前面“路为雪覆盖”和后面“他们骑摩托”得知此处应当是因果关系,故选择why。表示我不解的原因。句意:路上都是雪。我不明白他们为什么坚持骑摩托车去。4. C 该题考查名词性从句。关联词在宾语从句中作宾语,故选what。句意:我认为父亲想知道我迄今在忙什么;因此我决定给他寄一个快笺。5. B该题根据交际情景考查名词性从句的用法。it是形式主语,后面是主语从句因此用陈述句语序。选择B最佳。句意:我一直诚实坦率,我和谁说话并不重要。6. B该题根据交际情景考查名词性从句的引导词的用法。关键词是important需要副词how修饰。由how important引导宾语从句。句意:要教会父母懂得教育对孩子的未来是多么重要。7. A该题根据交际情景考查名词性的用法。根据题目此处作in的介词宾语,在从句中作主语故选what。句意:在10年前还是废墟的地方,一座现代化的城市拔地而起。8. B 考查名词性从句的用法。这是一个复杂句,首先是一个由after引导的时间状语从句,在主句中又包含一个主语从句,引导词在主语从句中作宾语,因此,用what。句意:杨利伟成功环绕地球后,我们的宇航员期望的是太空漫步。9. D 考查名词性从句的用法。本句是一个含有同位语从句的句子,story与that从句是一种同位关系,也就是说,that从句说明story的内容,因此D正确。10.D 该题考查主语从句中形式主语的用法。为了保持句子结构平衡,用形式主语it代替,把真正主语放在句子后面。句意:那位外长说:“我们希望双方向好的方向努力。”11. C 该题考查名词性从句中引导词的用法。据题意:我没想不出为什么大量的昆虫、鸟和动物濒临灭绝。此处是表示原因。12.C 考查名词性从句,It在句中作形式主语代替后面的主语从句,在主语从句中又缺少主语,应选择连接代词,既起连接作用,又担当句子成分,因此选择C。句意:现在已相当清楚是什么在控制着二氧化碳初入大气的流动。13.A 考查名词性从句与动词need。a new problem与road conditions need是一种同位关系;improve与road condition之间是一个动宾关系,因此need如果后接不定式应用被动语态,如接动名词应用主动形式表示被动的意思,A为正确答案。14.A 考查名词性从句,在此句中从句与feeling形成一种同位关系,说明feeling所包含的内容,that为正确答案。15.A 考查虚拟语气在宾语从句中的用法,从以下两点来考虑(1)suggest后接的宾语从句应用虚拟语气,动词用原形或should+动词原形(2)suggest后接宾语从句,其疑问和否定形式前移到主句。16.A 考查名词性从句,Thats后面的部分是一个表语从句,所选择的连接词在表语从句中作宾语,因此选择连接代词what。17.C 考查虚拟语气在宾语从句的运用。Imagine的宾语从句谓语动词用(should)+动词原形。18.B. 考查名词性从句连接词的用法。information与that more middle school graduates will be admitted into the universities是一种同位关系,后者说明前者所包含的内容与信息。that只起连接作用,不能省略。19C 该题考宾语从句连接词的用法。从题干中“to do”后缺宾语来判断,所填的词一定同时满足两个条件:引导宾语从句(作“can only do”的宾语);本身充当“to do”后的宾语,所以用what。句意:计算机只能按人们的指令去做事。20 B 该题考查由whatever引导的宾语从句的用法。该题的关键词是give 和want,give要接双宾语,所以从句是宾语从句,从宾语从句want看需要宾语,故选whatever。Whatever强调任意性,泛指;what强调特指。句意:普遍认为,孩子要什么就给他什么不是聪明之举。21 A该题考宾语从句连接词的用法。该题的关键词是答语中的by car,从此判断是对来的方式的提问,故用how 引导。句意:“你记得他怎么来的么?”“记得,他开车来的。”22 B该题考查名词性从句的用法。该题的关键是depend on (取决于)说明是表示选择,故用whether引导主语从句。句意:我们明天是否去野营要看天气而定。 23A该题考查名词性从句的用法。从题干看,两个空中所给之词分别作get和have的宾语,故都必须用what来引导。what和that 引导名词性从句的根本区别,what做成份而that只起到引导词的作用,不作成份。句意:我们得不到的似乎比我们所拥有的要好。24 D该题考查名词性从句的用法。It是形式主语,真正主语放到后面(Its + 名词 +that)以保持句子结构平衡。使用形式主语的情况还有:Its + 过去分词+ that; Its +形容词 + that; It happens/seems/appears that。句意:事实上英语作为国际语言正为世人所接受。25A该题考查名词性从句的用法。why引导的表语从句是说明had a few days off的原因。句意:“我上周开车去参加珠海的空展了。”“这就是你请了几天假的原因吗?”第二节 考点归纳在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此,我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。当名词性从句要采用陈述句语序。由一个含疑问意义的连词引起时,必须将该连词放在名词性从句的开头,且该从句语序不能倒装。一、引导名词性从句的关联词引导名词性从句的关联词大致相同,它们分别是:连词:that, whether, if;关系代词:who, what, which , whom, whose, whatever, whoever, whomever, whichever;关系副词:when, where, how, why, however, whenever, wherever。引导从句时一般不用逗号和主句分开。详细见下表:类 别词 义在从句中的作用that无任何词义仅起连接作用,在从句中不充当任何句子成分if和whether意为“是否”,表明从句意义的不确定性起连接作用,在从句中不充当任何句子成分关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever有各自自身的意义起连接作用,并在从句中充当主、表、宾、定语等关系副词when,where,why,how, however, whenever, wherever有各自自身的意义起连接作用,并在从句中充当状语1、that从句与wh-关系代词和关系副词引导名词性从句的区别 连词that在从句中不作成分,不含疑问意义;而wh-连词在从句中作成分,且含有疑问意义;或what/where从句相当于一个名词后加一个定语从句。It worried her a bit that her hair was turning grey. 她的头发在变白令她有点担忧。(that在从句中只起引导词作用,不作成分)What caused the accident is still a plete mystery. 事故发生的原因仍然是个不解之谜。(What在从句中作主语) 2、that与whether引导名词性从句的区别。 (1)动词doubt表示“怀疑、不知道” 解时,肯定句接whether引导的宾语从句;否定句dont doubt和疑问句Do you doubt要接that引导的从句。 I dont doubt that he will e soon.我不怀疑他不久会来。(此处不用whether) Can you doubt that he will win?你怀疑他会赢吗?(此处不用whether)比较:doubt表示“不信”解时,表示强烈的不相信时,在陈述句中可接that从句。I doubt whether it is true.我怀疑那不是真的。 I doubt that he will stay there.我不信他会留在那里。(2)that本身无意义,有时可以省略;whether本身有意义,在句中均不可省略。 He said (that) he was from New York.他说他是从纽约来的。(that无意义,可以省略) Whether he will go there is not decided yet.他去不去没定下来。(whether 有意义,不可以省略)(3)如果宾语从句表示两种可能性据其一时,只能用whether(or not),不可用that。 I wonder whether he knew the manager(or not).我不知道他是否认识经理。(不能用that)I am not sure whether he will e.他来不来我没把握。(不能用that)(4)whether引导的从句能几乎作所有介词的宾语;that引导的从句只能作except, but, besides的介词宾语。I have no interest in whether he will e.我对他来与否不感兴趣。(不能用that)He is a good boy except that he is careless sometimes.他是个好孩子,只是有时有点粗心。3、whether和if的区别 (1)whether可以引导discuss,decide,consider和介词宾语从句,而if不能。 They are talking about whether they will go there.他们正在讨论是否去那里。(不能用if) (2)whether可以应到所有的名词性从句,而if只能引导宾语从句;在引起主语从句时,特别是主语从句在句首时,不能用if,除非是有形式主语it的主语从句。 Whether the xx Olympic Games will be held in Beijing is not known yet. xx年奥运会是否在北京举行还不知道。(不能用if) (3)whether后可以直接跟or not或or no,构成whether or not或whether or no,if则不能。但可以说whether/if or not, whether/if or。I dont know whether or not hell e. 我不知道他是否会来。(不能用if)(4)if 引导的从句可用于否定的谓语,whether引导的从句不用于否定的谓语。 I dont care if you wont e.我才不在乎他来不来呢。 (5)whether or可以引导让步状语从句,or不可省略;if可以引导条件状语从句。 Whether it snows or not, I will go there by bike.不论明天下不下雪,我都骑车去。 If he had been given more time, he could have done it much better. 如果给他更多的时间,他会做得更好。(6)whether可以和不定式连用,而if不能。 He didnt know whether to get married or to wait.他不知道是现在结婚还是等等再说。They havent decided whether to go there or not.他们还没决定去不去。(7)whether和if引导的宾语从句,可以用肯定,也可以用否定,但含义不同。He asked whether she could help.他问她是否能帮忙。(表示疑问,可加or not) He asked whether she couldnt help.他认为她能帮忙。(表示否定,不可加or not)巧记whether与if异同“whether”与“if”都可表“是否”,是常考内容。下面的顺口溜可帮你记住其异同。主从表从同位从,if不用whether用;discuss和介词后,whether引宾从;不定式、or not后面跟,whether独能显神通;宾从如是否定句,if发挥其功用;避免歧义要慎重,其它情况可换用。4、关系代词与关系副词引起的名词性从句的应当注意的问题(1)wh-ever引起的名词性从句不含疑问意义,相当于不定代词后加一个定语从句:whatever = anything that,whoever=anyone who, wherever=any place where, whenever=any time when表示泛指;而what,which,who,when,where,how等词都有时含有疑问意义,表示特指。A puter can only do what you have instructed it to do. 计算机只能按人们的指令去做事。(特指) It is generally considered unwise to give a child whatever he or she wants. 普遍认为,孩子要什么就给他什么不是聪明之举。(泛指)(2)介词后的who/whom,whoever/whomever的选择问题,则要看连接词在从句中是作主语还是作宾语而定,如在从句中作主语则只能选用who/whoever。Give them to whoever is likely to be interested.把他们送给感兴趣的人。(不能用whomever)Who do you think is the best student?你认为谁是最好的学生。(不能用whom)(3)正确使用who/ whoever,what/whatever,how/however,where/wherever,when/whenever,which/whichever,who,what,where,when,how,which一要分析句子结构,看其在从句中作何成分,二是理清其在句中的含义。-I drove to Zhuhai for the air show last week. 我上周开车去参加珠海的空展了。-Is that why you had a few days off? (表原因)这就是你请了几天假的原因吗?I remember when this used to be a quiet place.我记忆中这里曾经是一个安静的地方。(表时间)二、主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whether,关系代词:who, what, which , whom, whose, whatever, whoever, whomever, whichever;关系副词:when, where, how, why, however, whenever, wherever等。1、 从属连词that,whether引导的主语从句。从属连词that,whether在主语从句中的作用只是引导主语从句,它们在从句中不担任成分,不能省略。That you dont like him is none of my business.你不喜欢她不管我的事。Whether she will e or not is still a question. 她是否会来仍是一个问题。2、 it作形式主语引导主语从句。如果主语从句太长,为避免句子结构头重脚轻,我们可用it作形式主语,而把主语从句放在主句谓语部分之后。That引导的主语从句可用it代替,that 不可省略。 用作it作形式主语的结构: It is/was +形容词+that 从句 Its natural that 很自然 Its obvious that 显而易见 Its fortunate that 幸运的是 Its (im)possible(不)可能 Its unlikely that 不可能 Its strange that奇怪的是 It is/was +名词+that 从句 Its a pity that 遗憾的是 Its a fact that 事实是 Its good news that是好消息 Its a wonder that不足为奇 Its an honour that 非常荣幸 Its a shame that真是可耻 Its mon knowledge that 是常识 It +不及物动词+that 从句 It seems that 似乎 It happened that碰巧 It appears that看来 It turns out that结果 It is/was +过去分词+that 从句 Its not known that 不得而知 Its said that 据说 Its reported that 据报道 Its decided that尚未决定 Its believed that 据认为 Its announced that据宣布 It suddenly struck me (occur to me that 我突然想到(感觉到) 其他 It doesnt matter 是无关紧要的 It makes no difference 毫无区别 It is of little consequence that无关紧要2、 由连接代词引导的主语从句。(1) 连接代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等,引导主语从句时,它们分别在从句中担任主语、宾语或定语,不能省略。Whoever leaves the room last ought to turn off the lights.走得最晚的应当关灯。What you have done might do harm to other people. 你的行为可能伤害别人。(2)what引导主语从句“的东西/事情”时,可用来表示the thing(s)which这种意思,引导从句,表示一样东西与一件事情,这种用法的what称为关系代词型what,who,whom,which,what可以和ever构成合成词,和what一样引导从句,ever起强调作用。这些关系词在句子中充当成分,所以不能省略。此类主语从句不能用形式主语it引导。What I need (=The thing which I need) is a mobile phone.我所需要的是一部移动电话。Whoever leaves the office (=Any one who leaves the office)should tell me.无论是谁离开办公室都应该告诉我。3、连接副词引导的主语从句。连接副词有when, where, why, how, however, whenever, wherever等引导主语从句时,它们在从句中担任状语,不能省略。此类主语从句可以转换为以it作形式主语的句子。Why he didnt e here is not clear to anyone.他为什么没来谁也不清楚。三、表语从句用作表语的从句叫作表语从句,它位于主句中的连系动词之后。引导表语从句的词有从属连词that、whether、as though(if);关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等;关系副词when, where, why, how, however, whenever, wherever等。可以接表语从句的连系动词由be, look, remain, seem等。That引导表语从句时,在口语中,间或可以省略。1、由从属连词that,whether引导的表语从句。that在引导表语从句时无词义,而whether有词义,意为、“是否”。这时主句的主语常常是些抽象名词,如question(问题),trouble(麻烦),problem(问题),result(结果),chance(可能性),suggestion(建议),idea(想法),reason(理由)等。表语从句对主句主语进行说明、解释,使主语的内容具体化。 The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋。2、由关系代词引导的表语从句。关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句,在句中作主语、宾语、表语,关系代词不能省略。The question is which of us should go.问题是我们哪一个应该去。The problem was who could do the work.问题是谁能做这项工作。3、由关系副词引导的表语从句。Go and get your coat. Its where you left it. 去把雨衣拿来。就在你原来放的地方。That is what he is worried about. 那就是他所担心的。4、由连词because,as if/as though等引导的表语从句。It looked as if it was going to snow.看起来好像要下雪了。四、同位语从句用作同位语的从句叫同位语从句。它一般跟在抽象名词fact,idea,news,hope,belief,thought,truth,doubt,suggestion,warning, instruction,reason,information, question等之后,对这些名词进行说明或解释。引导同位语从句的词除连词that,whether外,还有关系代词what, which, who, 以及关系副词how,when,where,why等。1、由从属连词that,whether引导的同位语从句。I didnt receive the news that the meeting had been put off.我没有听到会议被推迟的消息。2、由关系代词引导的同位语从句。You can have no idea what he said.你根本想不到他说了些什么。3、由关系副词引导的同位语从句。I have no idea when he will be back.我不知道他什么时候回来。4、定语从句与同位语从句的区别。(1)同位语从句相当于名词,它对其前的名词起补充说明或进一步解释其内容的作用;而定语从句的功能相当于形容词,它对其先行词起修饰、描述或限制作用。The suggestion (that) she has put forward is very good.她提出的建议很好。(定语从句)The suggestion that we clean the classroom by turns is very good.我们轮流打扫教室,这个建议很好。(同位语从句)(2)引导定语从句的that是关系代词,在从句中充当某种成分,作宾语时可省略;而引导同位语从句的that是连接词,在从句中不作任何成分,也不能省略。The fact (that) we talked about is important.我们所谈论的情况很重要。(定语从句,that作从句中介词about的宾语)The fact that he succeeded in the experiment pleased everybody.他的实验成功了,这使大家很高兴。(同位语从句,that在从句中不作任何成分)(3)引导定语从句的when,where是关系副词,不但在句中充当句子成分,还有与其含义相当的先行词;而引导同位语从句的when,where是关系副词,虽可以在从句中充当句子成分,但没有与之含义相当的先行词。Gone forever are the days when Chinese people were bullied.中国人民受欺侮的时候一去不复返了。(定语从句,the days与when构成含义相当的搭配关系)I have no idea when he will be back.我不知道他什么时候回来。(同位语从句,idea与when在含义上没有任何搭配关系)(4) 同位语从句的先行词应是表示抽象概念的词,如:idea, belief, conclusion, impression,fact,news,idea,thought,hope,order, suggestion,belief等,而定语从句的先行词是各种抽象概念的词或具体概念的词。He expressed the hope that he would write a novel someday.他表示希望有一天能写小说。(同位语从句)I will never forget the days when we were in Liangxiang together.我永远忘不了我们在良乡的日子。(定语从句)五、宾语从句(object clauses)用作宾语的从句叫做宾语从句。宾语从句的位置与陈述句基本结构中的宾语相同。宾语从句可作谓语动词的宾语,也可以作介词和非谓语动词(动词不定式、动名词、分词)和某些形容词的宾语。宾语从句可以由从属连词that whether、if,关系代词what, who, whose, which和关系副词when、where、how、why等引导。1、作动词宾语 (1)由从属连词that引导的宾语从句。that引导宾语从句时,只起引导词作用,在句中不做成分,在口语和非正式文体中常省去。I think (that) hell be right in a few days. 我认为他几天后就会好的。I wish (that) she would understand me.我希望她理解我。(2)由关系代词what, who, whose, which引导的宾语从句,在句中作成分,即主语、宾语、表语和定语,关系代词在句中不能省略。 A puter can only do what you have instructed it to do计算机只能按人的指令去做。Do you know whom they are waiting for?你知道他们在等谁吗?(3)关系副词when,where,how,why等引导宾语从句。关系副词 when,where,how,why 既有疑问意义,又起连接作用,而且在宾语从句中充当各种状语,分别表时间、地点、方式、原因。在句中不能省略。Please tell me when we shall discuss our plan. 请告诉我我们将何时讨论计划。I dont know where we are going to have the meeting. 我不知道我们将在哪里开会。(4)由从属连词whether或if引导的宾语从句。I wonder whether (if) daughters are valued as much as sons in the countryside. 我想知道在乡下女儿是否和儿子一样受到重视。I dont know whether (if) you are willing to help me. 我不知道你是否愿意帮我。注意:whether 和if的区别,请参考概述部分。(5)动词+间接宾语+宾语从句。动词如:advise, ask, inform, promise, question, remind, show, teach, tell, warn等,宾语从句前可以有一个间接宾语,这个宾语有时可以省略,有的不能省略。He has informed me when they are to discuss my proposal.他已经通知我们将什么时候讨论我的建议。(me不可省略)She promised (us) that she would give us more help later on.她答应以后给我们更多的帮助。(us可省略)2、作介词宾语It depends on whether he is ing or not. 这要看他是否会来。I was curious as to what we could do next.我想知道下一步我们该做什么。注意:that引导的宾语从句只在in, but, except,besides等少数介词后作宾语,形成固定搭配,in that在于(因为),but that要不是(只是),except that除了。The higher ine tax is harmful in that it may discourage people from trying to earn more.所得税过高是有害的,因为它可能使人不愿多赚钱。3、 作形容词宾语。that引导的从句在下列形容词后面作宾语,that可以省略。Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content, proud等。I am not certain whether I have met him before.我不能肯定从前是否见过他。Im sorry (that) youre ill. 你病了,我很难过。4、it充当形式宾语,真正的宾语-宾语从句后置。正如我们常用it充当形式主语代替主语从句一样,我们也常用it用作形式宾语代替宾语从句,把真正的宾语从句后置。特别是带复合宾语的句子中。在这种结构中that不可省略。有下列几种情况:(1)在believe, consider, declare, estimate, fancy, feel, find, guess,hear, imagine, know, make, prove, reckon, think, understand 等动词接复合宾语(宾语宾补)时,要用it作形式宾语。She thinks it wrong that he didnt answer the phone她认为他不接电话是不对的。 (2)在like,enjoy,love,hate,take 等表“喜怒哀乐”的动词,后若要跟宾语从句时,需跟形式宾语 it。I hate it when people talk with their mouths full.我不喜欢人们满口饭说话。 I like it that everyone passed the exam都通过了考试我很喜欢。 (3)由动词和介词构成的短语动词后接 that 宾语从句时,要用形式宾语。如: We are thinking of it that well lend you some money我正在考虑借给你钱的事。I shall see to it that he is taken good care of when you are absent.你不在的时候我负责把他照顾好。(4)用于“动词+宾语+介词短语”的句型中。Keep it in mind that you have to be home by ten oclock.要记住你得十点钟之前回家。We took it for granted that he would e.我们认为他来是当然的。(5)不可直接跟that从句的动词。下列动词不可直接接that从句:ask, refuse, let, like, cause, force, condemn, admire, celebrate, entreat, dislike(厌恶), overlook, love, help, take, forgive, bid, hate, hear(听见), see(看见), want(想要) 等,但可用it, the fact做媒介,后接that从句;或接动名词、不定式。He overlooked it that he had made another mistake.(正确)He overlooked the fact that he had made another mistake. (正确)He overlooked that he had made another mistake.(错误)他忽视了一件事,他又犯了一个错误。I admire it that they won the match. (正确)I admire the fact that they won the match. (正确)I admire that they won the match. (错误) 我很羡慕,他们赢得了比赛。5、that引导宾语从句的省略。(1) 主句谓语动词是agree, argue, hold, learn, maintain, observe, contend, conceive, reckon, remark, state, suggest, assume, announce, calculate, indicate等时,其后宾语从句的引导词that一般不可省略;主句谓语动词是hear, know, say, see, confess consider, declare, understand, propose等时,其后宾语从句的引导词that可以省略,也可以不省略;主句谓语动词是think, suppose, believe, presume, dare say等时,其后宾语从句的引导词that可以省略。He suggested that we should set off at 8 oclock tomorrow morning.他建议我们明天早晨8点走。(that不可省略)I think (that) this is very important.我认为这很重要。(that可省略)(2) 当一个句子很复杂,句中有多个状语时,that不可省略;或者一个句子有多个并列的宾语从句时,特别第一个宾语从句特别长,后面的宾语从句的that不可省略;谓语动词与that从句之间有插入语时,that不可省去。He said you neednt worry and that he would help you . 他说你没有必要着急,他会帮助你的。(said之后可省去that,但第二个that不可省去)We decide, as he has suggested, that we will start out tomorrow. 就
