1、卫辉一中2012届高三二轮备考抓分点透析之英语名词性从句【2012年高考命题预测】名词性从句涉及较为复杂的句式结构,是高中英语的一个重点语法,也是历年高考的高频考点。通过对近年高考题的分析,2012年高考应着重注意:1、名词性从句引导词的区别;2、that引导的同位语从句与定语从句的区别;3、某些固定搭配及句型在名词性从句中的用法。【重难点突破】【概述】名词在句中一般作主语、宾语、表语和同位语。能象一个名词一样在句中充当这些成分的从句就叫名词性从句。名词性从句包括主语从句、宾语从句、表语从句、同位语从句。常用的连接词有:连接词作用whether 是否that (本身无词义)只起连接词作用,引导
2、从句,在从句中不作任何成分who, whom, whosewhich 哪一个what 什么,所的在从句中分别作主语、宾语和定语在从句中分别作主语、宾语和定语在从句中分别作主语、宾语和定语when什么时候,where什么地方how怎样、怎么,why为什么除了起连接词作用外,还在从句中作状语疑问词(who, whom, whose, what, which, where, why, when, how)可以引导主语、宾语和表语从句。它们的特点是:1、疑问词有本身的词义;2、疑问词在从句中担当句子成分,如主语、宾语或状语;3、这种疑问词引导的从句一律用陈述语序,不能用疑问语序。Do you know
3、 whom they are looking for? 你知道他们在找谁吗?(宾语从句,陈述语序。不能是whom are they looking for?)I dont know who did it.我不知道这是谁干的。(宾语从句。在从句中如果疑问词作主语,其陈述语序和疑问语序一致。)She asked me where I had been.她问我到哪儿去了。(宾语从句。陈述语序,不能是where had I been. 直接引语,间接引语。注意这句话的时态。)Can you tell me when the train will arrive? 你能告诉我火车什么时候到吗?(宾语从句。
4、陈述语序,不能是when will the train arrive. 直接引语,间接引语。)I dont know why he hasnt come yet. 我不知道他为什么还没来。(宾语从句,陈述语序。不能是why hasnt he come yet.)He didnt tell me what you were doing. 他没和我说你在干什么。(宾语从句,陈述语序。不能是what were you doing.)What you have done might do harm t other people. 你所做过的事情有可能伤害别人。(主语从句。what 作从句的宾语。陈述语
5、序,不能是what have you done. 如果用疑问语序,意思发生了变化,成了“你做了什么?”。)来源:Zxxk.ComI dont know where he is now. 我不知道他现在在哪里。(宾语从句,陈述语序。不能是where is he now.)Where he went for his weekend is not known. 不知道他去哪里过的周末。(主语从句,where 作从句的地点状语。陈述语序,不能是where did he go for his weekend.)Whose fault this is is not important. 这是谁的过错并不重
6、要。(主语从句,whose 作从句的定语。陈述语序,不能是whose fault is this.)What I want to know is where he has gone for his weekend. 我想知道的是他到哪里度周末去了。(这句话包含两个名词性从句:what I want to know是主语从句,what 在从句中作宾语,从句用陈述语序,不能是What do I want to know. Where he has gone for his weekend 是表语从句,where 在从句中作状语,从句用陈述语序,不能是where has he gone for hi
7、s weekend.)下面我们再分别讲述主语从句、宾语从句、同位语从句和表语从句。一、主语从句1that 引导主语从句时,that 没有意义,但不能省略。(that 引导宾语从句时可以省略。)It worried her a bit that her hair was turning gray.她的头发正在变白,这使她很不安。that引导主语从句,it 作形式主语,that 不能省略。来源:Zxxk.ComThat she is a rich woman is known to us all. 众所周知,她是个富有的女人。这是that 引导主语从句,that 不能省略。这句话可以改为用it 作
8、形式主语的句型。请同学们改写:It is known to us all that she is a rich woman.)来源:学&科&网We didnt know (that) you had sold your house. 我们不知道你已经把你的房子卖了。这是that引导宾语从句,that 可以省略。注意这句话的时态。2从句作主语时,多数情况下由 it 作形式主语,而把主语从句放在后面,尤其是谓语部分(包括宾语)较短的情况下。It wasnt very clear what she meant. 不清楚她是什么意思。It is important that he should com
9、e on time. 他按时来是很重要的。It is true that that man on the left is a well-known writer here. 左边那个人是本地的一位著名作家,这是真的。这里,第一个that 引导主语从句,是单纯的连词,无词义,不作句子成分。第二个that 是指示代词,作句子成分,是man 的定语。3whether 既可以引导主语从句也可以引导宾语从句,但if不能引导主语从句。whether 后面可以加or not, 而if 不能与or not 连用。作介词宾语时不用if.如:Whether I knew John doesnt matter. =
10、 It doesnt matter whether I knew John. 我是否认识约翰没有关系。Whether or not shell come isnt clear. = Whether shell come or not isnt clear. = It isnt clear whether . 她是否来还不清楚。It all depends on whether we can get their cooperation. 这是主语从句还是宾语从句?it 是形式主语吗?it 是代词,whether 引导的是宾语从句,作介词on 的宾语,不能用if引导。请翻译这句话。这完全取决于我们
11、是否能得到他们的合作。I worry about whether I hurt her feelings.宾语从句,介词宾语,不能用if 引导。She asked me whether/if you were married. 宾语从句,既可以用whether, 又可以用if 引导。注意时态的对应。We havent decided whether/if we shall give them aid. Im not sure whether/if the report is believable. Now lets do some translation:现在还很难预测谁会赢得下一届总统选举。
12、It is still hard to predict who will win the next presidential election.对于多数公民来说,谁当选总统无关紧要。Who will become the president doesnt matter much to most citizens.这位前总统是否会被判处死刑还有待观察。It remains to be seen whether the ex-president will be sentenced to death. 真可惜,王教授不能出席我们的英语晚会。It is a pity that Prof. Wang c
13、ant attend our English Evening.我们需要的是更多的时间。What we need is more time. 二、宾语从句在谓语动词、介词、动词不定式、分词、动名词之后都可以带有宾语从句。某些形容词如sure, happy, glad, certain, pleased 等之后也可以带有宾语从句。1that 引导的宾语从句: that 没有意义,在口语或非正式文体中常省略I really feel shes making a mistake. 我的确感到她正犯错误。James said (that) he was feeling better. 詹姆斯说他感到好些
14、了。Hearing that his son was badly wounded, he hurried to the hospital to see him.听说儿子受了重伤,他急忙赶到医院去看望他。I suggested that we should go home. 我建议我们回家去。虚拟语气,that 一般不能省略。2whether/if (是否)引导的宾语从句:如果要突出“究竟是还是不”,常在whether 后面加or not; if 一般不与or not连用。如: He asked me if/whether I knew John. 他问我是否认识约翰。Let me know w
15、hether you can come or not. 你能来还是不能来,告诉我一声。3在think, believe, suppose, expect 等动词的宾语从句中,否定不用在从句中,而是将think 等词变为否定形式。I dont think the film is interesting.我觉得这部电影没什么意思。 I dont suppose we are going outing tomorrow. 我认为我们明天不会出去郊游。4如果从句作宾语而后面还有补语,为了保持句子的平衡,用it 作形式宾语,而将宾语从句放在句尾。常跟这样的复合宾语的动词有:make, find, see
16、, hear, feel, think, consider, regard, take.for granted等。George made it clear that he opposed this project. 乔治已明确表示他反对这个项目。it 代表that 引导的句子,作宾语,clear 是宾语补足语。They kept it quiet that he was dead. 对他已经死亡的消息,他们秘而不宣。I took it for granted that youd stay with us. 我想当然认为你会和我们呆在一起。三、同位语从句同位语从句是对名词的内容给予具体、详细的说
17、明。常在后面接同位语从句的名词有fact, news, idea, truth, hope, suggestion, question, problem, doubt, fear, belief等。同位语从句常用的引导词为that,有是也用when, where 等疑问词。The news that the United States was hit by terrorist attacks took the whole world by surprise. 美国受到恐怖主义分子袭击的消息令全世界吃惊。The idea that you can do this work well withou
18、t thinking is quite wrong.你认为不动脑筋就能做好这件工作的想法是完全错误的。People used to hold the belief that the earth was the center of the universe. 人们曾认为地球是宇宙的中心。The difficulty lies in the fact that we are short of money.困难在于我们缺乏资金这个事实。They have no idea at all where he has gone.他们一点儿也不知道他去哪儿了。注意:同位语从句的that 只是引导词,没有其他语
19、法作用,在句子中不作句子成分,不能省略;而定语从句中的that 除了引导定语从句外,还是定语从句的一个成分,在定语从句中作主语或宾语,作主语时不能省略,作宾语时可以省略。The idea that some peoples are superior to others is sheer nonsense.有些民族优越于其他民族这种想法简直荒谬。(请辨别是同位语从句还是定语从句。)(同位语从句)The idea that he proposed at the meeting is sheer nonsense. 他在会议上提出的这个想法简直荒谬。(请辨别是同位语从句还是定语从句。)(定语从句)N
20、o one is happy with the fact that he found out. 没有人对他发现的事实感到高兴。(请辨别是同位语从句还是定语从句。)(定语从句)No one is happy with the fact that he will become their boss.没有人对他将成为他们的老板这一事实感到高兴。(请辨别是同位语从句还是定语从句。)(同位语从句)四、表语从句表语从句位于主句的连系动词之后,在非正式文体中引导词that可以省略。Thats not what I want. 那不是我要的。Thats why I have come.那就是我为什么来了。My
21、 opinion is that things will improve.我的意见是事情会好起来的。One advantage of solar energy is that it will never run out. 太阳能的一个优点是永远也不会枯竭。The truth is that he didnt really try. 实际情况是他没有真正努力。The problem is who is to pay and when we can start.问题是谁来付帐、我们又何时开始。The fact is that he didnt notice the car until too la
22、te. 事实是他注意到车时已经太晚了。What surprised me was that he spoke English so well.使我感到吃惊的是他英语讲得那么好。All I can say is that I have nothing to do with it. 我能说的就是我与此事没有关系。What I want to know is where we shall go and whether she will join us. 我想知道的是我们要去什么地方以及她是否加入我们。此外,表语从句还可由as if (好像)引导。It looked as if it was/were
23、 going to rain. (虚拟语气)Now lets do some translation:这就是她昨天请一天假的原因。That is why she had a day off yesterday.我的想法是,个人的权利应该得到充分尊重。My idea is that individual rights should be fully respected.问题在于上帝是否真的存在。The question is whether the God really exists. 我想知道的是,他是如何在这么短的时间内完成这个项目的。What I want to know is how h
24、e managed to complete the project in such a short time.一、名词性从句连接词的选用: if 和whether:whether 和if在引导宾语从句时,意思是“是否”,这时if并没有“假设,如果”的意思;引导主语从句、表语从句、同位语从句以及介词后之宾语从句,不能用if, 只能用whether;多数情况下引导动词之宾语从句可用if 或 whether; whether引导的从句中可以有or not, if 引导的从句一般没有or not。(2011山东卷)33Weve offered her the job, but I dont know_
25、 shell accept it【C】Awhere BwhatCwhetherDwhich(2011重庆卷)22It is still under discussion _the old bus station should be replaced with a modern hotel or not【A】AWhether Bwhen Cwhich Dwhere that 和what:that 和what都可引导主语从句、宾语从句、表语从句(what通常不引导同位语从句,而that则可以)。what除起连接作用外,还在名词性从句中充当成分,可作从句中的主语、宾语或表语。而that在名词性从句中
26、不充当任何成分,只起连接作用。(2011天津卷)13Modern science has given clear evidence _ smoking can lead to many diseases【C】Awhat Bwhich Cthat Dwhere(2011江西卷)26The villagers have already known _ we will do is to rebuild the bridge【C】Athis Bthat Cwhat Dwhich 其他连接代词和副词的选用:主要根据名词性从句中的具体意义,正确地选择who, which, when, where, why
27、, how等连接词。这些连接词即有疑问含义,又起连接作用,同时在从句中充当各种成分,其区别从词义上是显而易见的。whoever, whatever, whichever 等也可引导名词性从句,其意分别为“所的一切事或东西”、“任何的人”、“的任可人或物”等。如: Whoever wants the book may have it. 任何人要这书都可拿去。 Ill do whatever I can to help him. 我们将尽我们所能来挽救他。 Buy whichever is cheapest. 买最便宜的。 注意以下受汉语意思影响而弄错的句子: 任何人来都欢迎。 误:Who com
28、es will be welcome. / Anyone comes will be welcome 正:Whoever comes will be welcome. / Anyone who comes will be welcome. 另外,它们也可引导让步状语从句,其意为“无论”、“不管”,其意相当于 no matter who what, which。如: Whatever happens, you must be calm. 不管发生什么情况,你都必须镇静。(whatever = no matter what) He wont eat you, whoever he is. 不管他是
29、谁,他也不能把你吃掉。(whoever = no matter who) 注:whoever 既用作主格也用作宾语;作宾语时不宜用 whomever,因为在现代英语中 whomever 这个已几乎废弃不用。(2011山东卷)26Im afraid hes more of a talker than a doer, which is _he never finishing anything【D】Athat Bwhen Cwhere Dwhy(2010浙江)How about camping this weekend, just for a change?OK, you want. 【C】Awhi
30、chever Bhowever CwhateverDwhoever(2010上海)37. When changing lanes, a driver should use his turning signal to let other drivers know .【B】A. he is entering which lane B. which lane he is enteringC. is he entering which lane D. which lane is he entering 4. why 与 because 的用法区别。两者均可引导表语从句,但前者强调结果,后者强调的原因。
31、如: I had a cold. Thats why I didnt come. 我感冒了,因此我没来。 I didnt come. Thats because I had a cold. 我没有来,那是因为我感冒了。5. 引导词that的省略主语从句、表语从句、同位语从句、用it作形式宾语的宾语从句及并列宾语从句中的后几个从句,that都不能省略。只有单个宾语从句中的 that 可以省略。(2010上海)36. One reason for her preference for city life is she can have easy access to places like shop
32、s and restaurants.【A】A. that B. how C. what D. why(10北京)32.

The news _(房价将要下跌)has ca
33、used many people to sell their houses at lower prices. (fall) 答案:that the housing price will fall三、同位语从句和定语从句的区别:定语从句是先行词的修饰语,它不涉及先行词的具体内容。如果定语从句是用that引导,that在从句中不但起连接作用,而且在定语从句中充当一个句子成分;同位语从句对中心词的内容作进一步的解释和说明,表明中心词的具体、实际内容。引导同位语从句的that在同位语从句中不作任何成分,只起连接作用,无具体词义,且不可省略。(2011辽宁卷)32When the news came t
34、he war broke out, he decided, to serve in the army【C】 (同位语从句)Asince Bwhich Cthat Dbecause(2011山东卷)32The old town has narrow streets and small houses _are built close to each other【D】)(定语从句)Athey Bwhere Cwhat Dthat四、名词性从句在固定搭配、固定句型中的用法1、由连词that引导的主语从句,在大多数情况下会放到句子的后面,而用代词it作形式主语。常见的以it作形式主语的主语从句句型有四种
35、:It + be + adj.(strange/ natural/ surprising/ obvious/ true/ fortunate/ wonderful/ funny/ possible/ impossible/ likely/ unlikely/ clear/ unusual/ certain/ important) + that It + be + no wonder/ a pity/ a shame/ a fact/ an honor/ good news + thatIt + be + said/ reported/ believed/ understood + thatIt
36、 + seems/happens/appears/doesnt matter/makes no difference + that(2011湖南卷)31 Before the problem can be solved, it must be obvious _the problem itself is 【A】Awhat Bthat Cwhich Dwhy(2010浙江)It is uncertain side effect the medicine will bring about, although about two thousand patients have taken it.
