高考英语名词性从句学案概念与分类 名词性从句相当于名词,可分别在句中作主语、表语、宾语和同位语。因此,名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。w.w.w.k.s.5.u.c.o.m 从属连词that:在从句中不充当任何成分,也没有任何意思,只起连接作用,因此往往可以省略从属连词if, whether:在从句中不充当任何成分,有意义,不可以省略连接代词who, whoever, whom, whomever, which, whichever, what, whatever, whose:在从句中充当成分,有意义,不可以省略连接副词where, when, why, how:在从句中充当成分,有意义,不可以省略一、主语从句.由从属连词引导的主语从句:_is something we must discuss. 那个国高考资源网家是否应该建立核电站_is known to all .光以直线传播.由连接代词引导的主语从句:w.w.w.k.s.5.u.c.o.m _ more time. some books.我们所需要的是_ doesnt matter to me.无论你选哪本书_www will be welcome.无论谁来.由连接副词引导的主语从句:_hasnt been announced.飞机什么时候起飞_ is still a puzzle.他到过哪儿How much water is flowing can be measured easily.水的流量是多少4.关于形式主语 it It + be +形容词+ that-从句 It is necessary that 有必要 It is important that 重要的是 It is obvious that 很明显 It is likely that.很可能It + be + -ed 分词+ that-从句 It is believed that人们相信 It is known to all that众所周知 It has been decided that 已决定 It + be +名词+ that-从句 It is common knowledge that 是常识 It is a surprise that 令人惊奇的是 It is a fact that 事实是 可应用于此句型的名词还有fact / shame / honor / question/pity等。 It +不及物动词+ that-分句 It appears that似乎 It happens that碰巧 It occurred to me that 我突然想起 It doesnt matter whether he likes or not. 二、表语从句可以接表语从句的连系动词有 be, look, remain, seem 等。The problem is_ caused by smoking.数百万人死于由抽烟引起的疾病The question remains_.我们是否能赢得这次比赛 Thats just what I want. 我想要的This is_. 我们的问题所在The difficulty is how we can help smokers kick their habit我们如何帮助吸烟的人值得注意的是:1. 表语从句的表现形式除了用从属连词,连接代词和连接副词引导以外,还可以由as, as if ,as though引导.Things were not as they seemed.It looks as if it is going to rain.好象要下雨了。2、另外还要注意以下常用的两种结构:The reason whyis that (而不用 because)It ( This, That ) is becauseThe reason _ he was dismissed is _ he didnt work hard. 他为什么被开除是因为他工作不努力。It is _ the tobacco companies want to remain in business.同时还要注意:(1)引导表语从句的that不省略, that仅起连接作用, 在从句中不充当任何成分, 无任何意义。The impression he makes on me is _ he is a reliable person.(2)the reason后面的表语从句只能用that引导, 我们学生易犯“the reason is because”的错误。The reason_ the little actress has been such a success is _ she is both clever and hard-working. (3)在表示命令order等, 建议suggestion, advice等的名词后的表语从句中, 谓语动词要用虚拟语气: should+动词原形, should可省略His suggestion is that we _ hold another meeting to discuss the problem.(4)whether可引导表语从句, 表“是否”, 它在从句中不充当成分, if则不能。The question is _we can rely on him.(5)连接代词what, which, who, whom, whose除起连接作用外, 还在从句中做主语、宾语、表语和定语。Thats what he is worried about.(在从句作中作_)The problem is who can do the work.(在从句中作_)(6)连接副词when, where, why, how起连接作用外, 还在从句中作状语。Thats _I was late. That is _he did it.(7)连词because引导表语从句, 只用在 That/This/It is because结构中That is _ she often works hard.三、宾语从句一)引导词的选择 宾语从句的引导词除that只起连接作用外,其他的都有各自具体的意义。因此我们在选择引导词时,要把句型结构、句意及习惯搭配结合起来,做全盘考虑。请看下面的例句:Youll have to decide _ car well use, yours or mine Youll have to decide _ car well use, the old one or the new one Youll have to decide _well use the new car for Youll have to decide _well use the new car Awhich Bwhat Cwhose Dwhether 再如:I still remember _ this used to be a small village另外,要特别注意:动词或动词短语check,make sure等作肯定句的谓语时,全句在汉语意义上虽有“是否”之意,但后面常用that作引导词。如: Check _ everything is in order,please 请核对一下是否一切正常。 Make sure _ the door is locked before you leave the lab在离开实验室前,务必弄清门是否锁上了。 二)that的省略与否 that在口语中常省略。但在下列情况下,that一般不能省略: 1that从句置于句首以示强调或作简短回答时,如: That he has never seen such a thing I simply cant believe What do you assume from his attitude 你从他的态度推测到什么? That he was frightened 他很害怕。 2及物动词所带的第二个及以后的宾语从句中。 He said_ Lesson 82 was important and _ he should learn it well 他说第82课重要,他应学好它。3that从句被短语、词组分开时。如: He told us once again _he would never give up 他再次告诉我们他决不会放弃。 4在复合宾语中。如: He made it clear_he wouldnt give us an answer 他表明他不会给我们答复的。 三)从句的谓语动词的形式 当主句时态为一般过去时时,宾语从句的时态一般受其影响,要用过去的相应时态。并且,此影响延伸至宾语从句中定语从句、状语从句等。如:He said he _ come if he_time 他说有时间他会来。 但下列两种情形例外: 1当宾语从句为客观真理或普遍事实时,只用一般现在时。如: The voyage proved that the earth is round 那次航海证实了地球是圆的。 2当主句谓语动词为suggest, insist, demand等时,其宾语从句常用should型的虚拟语气,谓语为(should)动词原形。如: He demanded that they (should) be there on time 他要求他们按时到那儿。 四)从句的语序 在宾语从句中只用陈述语序。如: He was not satisfied with_ 他对我说的不满意。 He asked _.他问怎么啦。 五)混合型的宾语从句 当主句谓语动词为thinksupposeexpectbelieve等时,且其后的宾语从句为否定句,常将否定词not从从句中转移到主句中,构成否定转移;疑问句中what, who, how等要放在句首,构成混合型的宾语从句(也可把主句视为插入语)。如: We dont think theres anything of interest in your picture,_? 我们认为你的画没有什么有趣的地方。 What do you suppose_ 你推测他们需要什么? 六)动宾介宾形宾从句七)whether与if在宾语从句中的区别: 1、介词之后的宾语从句,不可用if连接,要用whether。e.g. Im interested in _youve finished the work.2、whether与if都可以引导宾语从句,常可互换。但下面情况不能互换。宾语从句是否定句时,只用if,不用whether。e.g. I wonder _ it doesnt rain.宾语从句中的whether 与or not直接连用,就不能换成if;不直接连用,可换。e.g. I dont know whether or not the report is true.I dont know whether/ if the report is true or not.介词后的宾语从句要用whether引导。whether 可与不定式连用。whether也可引导主语从句、表语从句、同位语从句,还可引导让步状语从句,以上均不能换成if。e.g. It depends on _we have enough time. They dont know _ to go there.四、同位语从句 在复合句中充当同位语的名词性从句称为同位语从句。同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一,在使用同位语从句时,应注意:一)同位语从句在句中的位置1.一般情况下同位语从句跟在某些名词(如news,idea,fact,promise,hope,message等)的后面,用以说明该名词所表达的具体内容。例如:The news _had won the championship encouraged us all greatly.我们女排赢得冠军的消息大大地鼓舞了我们所有人。Ive come from Mr Wang with a message _this afternoon.我从王先生那边得知一个消息,他说他今天下午不能来看你了。2.有时同位语从句可以不紧跟在它所说明的名词后,而被别的词语隔开,在语法上叫做分隔式同位语从句。例如:The thought came to her _when she left home.她突然想起可能在她离开家时没把门关上。The story goes _again.据说他高考又落榜.二)同位语从句前名词的数同位语从句前的名词通常用单数形式,并且往往带有限定词(word除外)加以修饰。如:Where did you get the idea _ I could not come?你在哪儿听说我不能来?Give me your promise _you will come to our party this evening.答应我,你今天晚上要来参加我们的晚会。Word came _China launched its first manned spaceship on Oct 15,2003.消息传来,中国于2003年10月15日首次成功发射了载人飞船。三)同位语从句连接词的选用在英语中,引导同位语从句的词通常有连词(that,who,whether),连接副词(how,when,where)等。例如:They were all very much worried over the fact _ you were sick.对你生病这件事,他们都很焦虑。The question _ should do the work requires consideration.谁该做这项工作,这个问题需要考虑。We havent yet settled the question _we are going to spend our summer vacation.我们还没有决定到什么地方去度暑假。注:在名词doubt“怀疑”后的同位语从句用whether连接;在no doubt“不怀疑”之后的同位语从句用that连接。例如:We have some doubt _ they can complete the task on time.我们怀疑他们是否能准时完成任务。There is no doubt _ Zhang Wei will keep his promise.我们相信张卫会守信的。同位语从句:that有些名词的后面可以接that引导的同位语从句:We came to the decision _.我们做出决定:我们必须立即行动。There was little hope_.他幸存的希望很小。以下名词常用于以上句型:advice,announcement,argument,belief,claim,conclusion,decision,evidence,explanation,fact,feeling,hope,idea,impression,information,knowledge,message,news,opinion,order,probability,promise,proposal,remark,reply,report,saying,statement,suggestion,thought,treat,warning,wish,word同位语从句:whetherwhether可以引导同位语从句,而定语从句不能用whether作为引导词。He hasnt made the decision _he will go there.他还没有做出决定是否去那里。I have small doubt _ he is suitable for the job.他是否适合这件工作我有点怀疑。同位语从句:what what可以引导同位语从句,而定语从句不能用what作为引导词I have no idea _he is doing now.我不知道他现在在干什么。同位语从句:how how可以引导同位语从句,而定语从句不能用how作为引导词Its a question _ he did it.那是一个他如何做了此事的问题。同位语从句:who等 who,whom,which,when,where,why用来引导同位语从句The question _should do the work requires consideration.谁该干这项工作,这个问题需要考虑。She raised the question _we could get the fund.她提出这个问题:我们到哪儿去搞这笔资金。四)同位语从句的语气在suggestion,advice,request,order等意为“建议;命令;要求”的名词后,同位语从句中的谓语动词通常用“should +动词原形”的虚拟语气结构,句中的should可以省略。例如:Our teacher gave us some advice_.老师给我们提出了一些如何使用电脑的建议。The suggestion came from the chairman _.采纳新规则的建议是主席提出来的。The government gave the order that_ in three weeks.政府下令三个星期内所有这些房子都要拆掉。五)同位语从句与定语从句的用法区别区别(1)同位语从句和先行词是同等的关系;而定语从句是用来修饰先行词,是从属的关系。区别(2)that在同位语从句中没有词义,不充当句子成分;而在定语从句中充当主语、宾语等句子成分。他带给我们的消息令我们非常高兴。 _他获胜的消息令我们非常高兴。_区别(3)whether,what,how可以用来引导同位语从句;而它们不能用来引导定语从句。区别(4)1.从词义角度看问题who,whom,which,when,where,why用来引导同位语从句是保持原来疑问词的含义;它们用来引导定语从句时,不具有疑问词的含义。 2.从搭配角度看问题who,whom,which,when,where,why用来引导定语从句时对应性很强,如:先行词是“人”,引导词用“who”等,而它们引导同位语从句是先行词通常是“question,idea,doubt等”。六、典型例题例1:I have no idea _he will be back.例2:I have no impression _ he went home,perhaps by bike.例3:Information has been put forward _ more middle school graduates will be admitted into universities.(NMET2001上海)A.while B.that C.when D.as区别:It is said that more middle school
