12、将会得到奖励。(3宾语从句1定义:用作宾语的从句叫宾语从句。2构成:关联词+简单句3引导宾语从句的关联词有三类:(1 从属连词that。如:He told us that he felt ill. 他对我们说他感到不舒服。I know he has returned. 我知道他已经回来了。注:that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下,that不能省略。1.Everybody could see what happened and that Tom was frightened.(and连接两个宾语从句,that宾语从句放在and的后面时,that不能省略。大家都会看出
13、所发生的事情并知道Tom非常害怕。2.I know nothing about him except that he is from the south.(that引导的宾语从句作介词宾语时,that不能省略。对他我一无所知,只知道他是南方人。3.That he ever said such a thing I simply dont believe. (that从句位于句首时,that不可省略。我简直不相信他曾说过这样的话。4.We decided, in view of his special circumstances, that we would admit him for a pro
14、bationary period. (主句谓语动词与that从句之间有插入语,that不可省略。鉴于他的特殊情况,我们决定应允他一段试用期。(2从属连词if/whether。如:I doubt whether he will succeed. 我怀疑他是否会成功。I dont know if you can help me.我不知道你能否帮助我。(3连接代词who, whom, whose, what, which, whoever, whatever, whichever连接副词where, when, how, why。如:Who or what he was, Martin never
15、learned.他是什么人?他是干什么的?马丁根本不知道。I wonder what hes writing to me about.我不知道他要给我写信说什么事。Ill tell you why I asked you to come. 我会告诉你我为什么要你来。You may do what you will. 你可做任何你想做的事。(1 介词宾语从句宾语从句也可用作介词的宾语。如:He was deeply displeased by what had occurred that day.他对那天发生的事感到很不快。I walked over to where she sat. 我走向她
16、坐的地方。I am curious as to what he will say. 我很想知道他要说什么。Your success will largely depend upon what you do and how you do it.你是否成功将主要取决于你做什么和怎样做。有时介词可以省略。如:I dont care (for who marries him.我不管谁跟他结婚。Be careful (as to how you do that. 你要注意做这件事的方式。1.如果宾语从句后还有宾语补足语,则用it作形式宾语,而将宾语从句后置。如: We thought it strang
17、e that Xiao Wang did not come yesterday.我们认为小王昨天没来是奇怪的。He has made it clear that he will not give in.他已表明他不会屈服。2.作介词的宾语:连词that引导的名词性从句很少作介词的宾语,只用在except, but, in后。其他一些介词的宾语从句如果由连词that引导,则需用it先行一步,作形式宾语。如:He is a good student except that he is careless.他是一个好学生,只是有点粗心。You may rely on it that I shall h
18、elp you. 你可以指望我会帮助你的。介词宾语不可以用which来引导,而要用what来引导。如:Are you sorry for what you've done?你为你所做的一切感到内疚吗?3.某些形容词或过去分词后常接宾语从句,这类形容词或过去分词有sure, glad, certain, pleased, happy, afraid, surprised, satisfied等,连词that可省略。如:I am not sure what I ought to do.我不能确定我该做什么。I'm afraid you don't understand wh
19、at I said.恐怕你没领会我说的意思。I'm surprised that I didn't see all that before.我好奇怪,我以前没看到过。Mother was very pleased her daughter had passed the exams.妈妈为她的女儿通过了考试而感到高兴。4.连词whether (or not或if引导的宾语从句if和whether引导的宾语从句可以互换使用,但whether常和or not连用,if一般不与or not连用。如:I wonder whether it is true or not. 我不知它是真是假
20、。用if引导宾语从句如果会引起歧义,应避免使用if而用wheter。试比较:Please let me know if you want to go.Please let me know whether you want to go.if从句可理解为宾语从句,意为“请告诉我你是否想去”;此句又可理解为条件状语从句意为“如果你想去的话,请告诉我一声”。5.宾语从句的否定转移。在think, believe, suppose, expect等动词后的宾语从句,有时谓语尽管是否定意思,却不用否定形式,而将think等动词变为否定形式。如:I dont think you are right. 我认为
21、你错了。I dont believe they have finished their work yet. 我相信他们还未完成他们的工作。I dont suppose he cares, does he? 我想他不在意,是吗?6.宾语从句的时态变化规律:(1 当主句是一般现在时态时,从句可根据需要用任何时态。(2 当主句是一般过去时态时,从句只能使用过去范围内的任何时态。但客观真理除外。如:The teacher said that the earth goes round the sun.7. what is / was the matter /wrong with sb作宾语从句, 不改变
22、语序;Who knows what is the matter / wrong with him?(4同位语从句1定义:用作同位语的从句叫做同位语从句。2.用法:同位语从句的先行词多为fact, news, idea, thought, question, reply, report, remark等,关联词多用从属连词that。如:They were all very much worried over the fact that you were sick.对你生病这件事,他们都很焦虑。Where did you get the idea that I could not come?你在哪
23、儿听说我不能来?注:同位语从句偶尔由从属连词whether引导。如:I have no idea whether hell come or not. 我不知道他是否来。1.that引导的同位语从句与定语从句之区别句法功能上that只起连接从句的作用,无意义。在从句中不充当句子成分。不可省。that替代先行词在从句中不仅起连接作用,还充当一个句子成分。如在从句中作动词的宾语时可省略。意义上从句是被修饰名词的内容。从句起限定作用,是定语如:The news that Mr. Li will be our new English teacher is true. (同位语从句,that不可省。李先生
24、将是我们的新英语老师这个消息是真的。The news (that he told me yesterday is true. (定语从句,that在从句中作told的宾语,可省。他昨天告诉我的消息是真的。2.一些表示“建议、命令、要求”的名词后所跟的同位语从句中,谓语动词用虚拟语气should+动词原形表示。should可省。如:This is our only request that this (should be settled as soon as possible.这就是我们唯一的请求:尽快解决这个问题。I wont believe the fact that he lied to
25、his mother.I wont believe the fact (that he told me. The news that Tom would go abroad is told by him. The news that he told me is that Tom would go abroad next year. We have no idea at all where he has gone.Thats the place where he was born三、考查关联词的正确选用这是近几年高考的重中之重。解决这一问题可以从以下几点入手:1.依据"缺什么补什么&q
26、uot;的原则确定正确的连词认真分析句子成分,看从句中缺什么成分,再根据语境和语义,选用恰当的连词。如果从句中缺少主语,指人用who,指物则用what或which;如缺宾语,指人用whom,指物用what;如缺时间状语用when;地点状语用where;原因状语用why;方式状语用how;定语用what 或which;如果从句中什么成分都不缺,用that。例如:I don't know who will be our English teacher next term.(缺主语,指人用whoI know what should be done and what shouldn't
27、 be done.(缺主语,指物用whatI'm sure that he will come tomorrow.(什么成分都不缺,用thatWhere he will go is still unknown.(缺地点状语,用whereI don't know which / what topic I should choose.(缺定语,用what或which2.注意几组易混连词的使用1 what与that这是高考测试的一对热点连词,同学们一定要将其掌握。that引导名词性从句时仅起连接作用,不作句子任何成分,除在宾语从句中外一般不可省略;what引导名词性从句时,除起连接作
28、用外,还在句子中担任主语、宾语、表语和定语等句子成分。all that, anyt hing that或the thing(s thatWhat we cant get seems better than what we have.Tom thought what a beautiful girl Mary was.whether与if在引导动词的宾语从句时,两者一般可以互换,但在引导主语从句、表语从句、同位语从句以及作介词宾语的宾语从句或后面直接跟or not时,只能用whether。高中英语语法强化训练(形容词性从句和名词性从句( 1.
