高中英语宾语从句详解

宾语从句详解1、概述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.He said he wanted to go to town.他说他想去城里.I hope you'll be better soon.我希望你能很快好起来.I’m so glad that you were able to come to this party.你能设法抽空出席这个交际会, 我很高兴.I know nothing about it except what I have read in the papers.除了在报上读到的以外,我对这件事一无所知.Most of the Chinese people usually go to work on the bike except when it rains.除了雨天,大多数中国人一般都骑自行车上班.He asked me whether she was coming.他问我, 她来还是不来.2、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)he'll 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 computer 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?He asked whose dictionary it was.他问这是谁的字典.He can't tell which method they will use for the experiment.他不能断定他们会用哪一种方法做实验.（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 don't know where we are going to have the meeting.我不知道我们将在哪里开会.Will you tell me how I can get to the station?你能告诉我如何能到车站吗?Do you know why he said that?你知道他为什么说那件事吗?I remember when this used to be a quiet village．我记得这里曾经是一个僻静的村庄.（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.我想知道在农村女儿是否和儿子一样受到重视.I don't 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.（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)3、作介词宾语It depends on whether he is coming 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 income 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.His paper is perfect except that there were some misprints.除了一些印刷错误之外, 这篇论文很好.4、作形容词宾语.No one can be sure what man will look like in a million years．谁也不知道一百万年后人类会变成什么样子.I am not certain whether I have met him before.我不能肯定从前是否见过他.I'm sorry(that)you're ill.你病了, 我很难过.注意：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,t hankful,ashamed,disappointed,annoyed,pleased,hurt,satisfied,content,proud等.I'm sure(that)he'll help you.我确信他会帮助你.I'm glad(that)he has passed the exam.我很高兴, 他考试及格了.5、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）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.

I want to know. →I want to know when he left.Does the shop close at six every day? Do you know? →Do you know if/ whether the shop closes at six every day?四、宾语从句要点之否定转移当主句的谓语动词为think, believe, suppose等动词,且主语为第一人称时,从句的否定要转移到主句上.例如:I don’t believe he is here on time, is he?I don’t think Tom is the best student in his class, is he?。
