Objectclause宾语从句用法和解释.doc

Object clause 宾语从句 用法和解释在句子中起宾语作用的从句叫做宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。宾语从句过三关：时态，语序，连词。1宾语从句的意义语法是语言的组织规律，任何人在使用语言时，不管他是否学过语法，但都必须合乎语法。另外，总结语法本身的规律也能加深我们对语言的理解，让我们能够真正熟练地运用语言。（宾语：指一个动作（动词）的接受者，常置于动词之后，也有双宾语结构例句：he gave me a book，类似拥有me和book两个宾语的句子叫双宾语从句），2用法宾语从句宾语从句的连接词：that结构：主语+谓语+宾语（陈述语序）注意：1. 引导词为that ；2. 语序为v.+主语+谓语 由if、whether引导宾语从句；3. 主句为现在时 从句为任一时态。1. 从属连词连接宾语从句的从属连词主要有that,if,whether，和疑问词（what， how， where， when .)。that引导表示陈述句的宾语从句，if和whether，whether.or not引导表示“是否”的一般疑问句的宾语从句。2. 关联代词连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。连接代词一般指疑问，但what,whatever除了指疑问外，也可以指陈述。3. 关联副词连接副词主要有when,where,why,how,whenever,wherever,however等。例句：He didnt tell me when we should meet again.他没有告诉我什么时候我们能再见面。注：宾语从句通常跟在名词或代词后面。动宾从句1. 大多数及物动词都可以带宾语从句。2. 部分“动词+副词”结构也可以带宾语从句。3. 动词短语也可以带宾语从句，常见的这些词有：make sure（确保）、make up ones mind（下决心）、keep in mind（牢记）4. 可运用形式宾语it代替的宾语从句动词find,feel,consider,make,believe,think等后面有宾语补足语的时候，则需要用it做形式宾语而将that宾语从句后置。5. 有些动词带宾语从句时需要在宾语与从句前加it（双宾语）这类动词主要有：hate,take,owe,have,see to.award,lend.hand,mail,offer,pass,pay,post,read,return,show,teach,tell介宾从句1. 用whether之类的介词宾语从句。2. 用that,if引导的介词宾语从句，有时候except,but,besides三个介词后可见到that引导的宾语从句。形容+宾从句有些形容词具有动词的含义，所以也可以带一个宾语从句；例句：1. I am sorry I am late.2. I am glad that you can join us.3. Are you sure his answer is right?常用来引导宾语从句的形容词有：sure,certain,glad,please,happy,sorry,afraid,satisfied,surprisedif与whether1. if和whether在作“是否”理解时，引导宾语从句常放在动词know,ask,care,wonder,find out等之后，介词后一般不用if。2. 少数动词，如：leave,put,discuss,doubt后的宾语从句常用whether。3. whether后可以加or not,但是if不可以。4. 在不定式前只能用whether。5. 一般“no matter”后表示“是否”用whether而不用if。不省略引导词that存在以下情况时引导词that不可省略：1. that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语。2. 宾语从句较长。3. 主语状语置于主句尾，宾语从句之前。4. 主语谓语动词（包括非谓语动词）与宾语从句之间有插入语。5. 一个动词带有两个或两个以上宾语从句时，第一个that可以省略，第二个that不可以省略。6. 宾语从句中的主语是this,that或this,that做主语的定语。7. 宾语从句是双宾语中的直接宾语。8. 宾语从句的主语是非谓语动词或主语从句。9. 主语中的谓语动词是固定词组。10. 宾语从句有it做其先行词。11. 直接引语中，转述分句把宾语从句隔开。12. that在从句中充当主语。否定转移主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess等，并且主句的主语是第一人称而且为一般现在时，从句的否定词一般要转移到主句上来，其反义疑问句一般与宾语从句一致.如果宾语从句中有某个含有否定意义的形容词或副词，其反义疑问句要用肯定形式.我们通常称为否定前移。时态和语序当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响.当主句为过去时从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生从句过去完成时表示该动作发生在主句谓语动作之前从句谓语用过去将来时表示该动作发生在主句谓语动作之后如果从句是一个客观真理，那么从句的时态不根据主句的时态而变化当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时，不能按正常语序安排，经常将这类引导词置于句首1. 无论任何时候都为陈述语序.3版本二学习宾语从句要抓住三要素：引导词、语序和时态。一、引导词1从句为陈述句，常选择引导词that或将that省略，直接与主句相连。2从句为一般疑问句，常选择引导词if或whether。在 whether or not 结构中不能用 if 替换。3从句为特殊疑问句，常选择what,when,where,which,who,how等疑问代词、疑问副词作引导词。 注意：当who为主语时，句式为：who+谓语+其他。1. 从句的引导词有很多，如：say, think, wish , hope, see, believe, agree, expect, hear , feel等。二、判断时态情况1主句是一般现在时，从句为各种时态。2主句是一般过去时，从句为各种相应过去时态。 注意：从句描绘客观事实，用一般现在时。3关系代词：that，who，whom,whose,which:1 The teacher told the children that the sun_ round.1. was B. is C. were D. are2 I believe that our team_ the basketball match.1. win B. wonC. will winD. wins答：1.B 2.C宾语从句用作宾语。如：Do you know where he lives?定语从句相当于一个形容词，用于修饰前面的名词。如：The student who answered the question was John. 回答问题的学生是John.This is the man whom he is looking for.三、宾语从句的用法1that引导宾语从句无意义，不充当句子成分常省略。但下列情况除外：介词宾语从句的that不能省略。 and连接的两个从句，两个从句的that不能省略。He told me that he had two sons and that they both had gone to college.在动词+it+宾语补足语+宾语从句结构中，that不省略。I heard it said that he had gone abroadWe found it impossible that he could finish it in such a short time1. Whether,if 引导宾语从句：两词可互换，但是下列情形除外：whether从句中有or notwhether从句做介词宾语Everything depends on whether you agree with us3许多带复合宾语的句子，宾语从句经常移到句子后部，而用it做形式宾语。结构是：主语 + 动词 + it + 形容词/名词等宾语补足语 + 宾语从句We think it wrong that he told a lie to everyone.宾语从句的语序要用陈述句语序。False: He is wondering when can he finish this difficult job.Right: He is wondering when he can finish this difficult job. 有时候可以用it 作形式宾语，而把真正的宾语从句放在后面。Bad: I thought that he could finish this job in just two hours impossible.Good: I thought it impossible that he could finish this job in just two hours. 带有宾语从句的复合句的否定形式一般是否定主句。Bad: I think he doesnt like the English teacher.Good: I dont think he likes the English teacher. 主句一般过去时态，从句也要用过去时态；具体细节请看第一部分。False: He wanted to know why he is crying in the corner.Right: He wanted to know why he was crying in the corner.4版本三宾语从句，在复合就叫，位于及物动词后。egTell him which class you are in Do you know what he likes？注：主句谓语过去时，从句相应过去时；He answered that he was listening to me.主句谓语现在时，从句时态任所需；eg He says (that) he will leave a message on my desk.They know (that) he is working hard.具体过去永不变，真理格言现在时；egHe told me that he was born in 1980.Father told me that practice makes perfect .（2）完成反意问句在think / believe / suppose / guess / imagine / expect等动词后跟宾语从句否定式时，应转移到主句上去，完成反意问句时，应与从句主、谓保持一致。（注： 否定前移的条件是，主句主语是第一人称）eg I dont think you are right,are youI dont believe they have finished their work yet,have they（3）运用虚拟语气在表示：建议 suggest 、advise、propose;要求demand 、desire、request；决定 decide;命令 order、command、require;坚决主张 insist;等动词后跟宾语从句，用（should）+v（虚拟语气）eg I suggested that you（should）study hardHe ordered that we should go out at once（4）宾语从句后置如果宾语从句后有宾语补语，用it作形式宾语，把宾语从句后置egYou may think it strange that he would live there（5）that不可省略宾语从句that常可省略，但在以下情况下不能省略A当主句谓语动词带有两个或两个以上宾语从句时，可以省略第一个that，其他不能省略。egI believe（that）you have done your best and that things will get betterB当it作形式宾语时egShe made it clear that she had nothing to do with himC当宾语从句前置时egThat our team will win，I believe5版本四一、定义和例句分析宾语从句就是一个句子作动词或介词的宾语。A 作动词的宾语：I heard the news.主语谓语动词名词作宾语Iheard that he would come here later on.主语谓语动词一个句子作宾语-宾语从句B 作介词的宾语：Hesaidnothing about the plan.主语谓语动词代词作动词的宾语介词名词作介词的宾语Hesaidnothing about who broke the window last night.主语谓语动词代词作动词的宾语介词一个句子作介词的宾语1. 二、复合句的构成带有宾语从句的复合句就是用连接词把一个主句和一个宾语从句连接在一起。连接词有：that(可省略)，what,who,when,where,why,which,if,whether,how.1 He suggested (that) we should clean the corridor every day.宾语2 He told me (that) he would leave Dalian airport at 8pm.间接宾语直接宾语3 He told me where he was going to travel that summer.间接宾语直接宾语4 if (whether) Tom could play basketball with him that morning.how she managed to solve the problem.why water flows from a high position to a lower position.在例子4中，当主句是过去时态时（一般过去时，过去进行时，过去将来时，过去完成时），从句根据不同情况必须使用过去时态的一种，（大自然的现象和真理除外）。5 if (whether) I have passed the exam.how my cat escaped from the room last night.在例子5中，当主语是现在时态时（一般现在时，现在进行时，一般将来时，现在完成时），从句可根据不同情况使用各种时态。1. 三、注意A 宾语从句必须用陈述语序。False: He is wondering when can he finish this difficult job.Right: He is wondering when he can finish this difficult job.B 有时候可以用it 作形式宾语，而把真正的宾语从句放在后面。Bad: I thought that he could finish thisjob in just two hours impossible.Good: I thought it impossible that he could finish this job in just two hours.Bad: He left whether we should continue this project to my judgment.Good: He left it to my judgment whether we should continue this project.C 带有宾语从句的复合句的否定形式一般是否定主句。Bad: I think he doesnt like the English teacher.Good: I dont think he likes the English teacher.D 主句一般过去时态，从句也要用过去时态；具体细节请看第一部分。False: He wanted to know why he is crying in the corner.Right: He wanted to know why he was crying in the corner.宾语从句的点点滴滴宾语从句是英语复合句中的其中非常重要的从句之一。它是用一个句子做另一个句子的宾语，将这个句子叫做宾语从句。宾语从句做介词或及物动词的宾语。现在从下列三个方面总结归纳如下：一，引导词A,由that 引导的陈述句性的宾语从句，在很多动词如say,think,wish,hope,see,believe,agree,expect,hear,feel等动词后。连词that只起连接作用，在从句中不做句子的成分，也无词汇意义，在口语中常被省略，但在大多数情况下还是以不省为好，特别是在笔语中。例：I told him that he was wrong.在think,believe,suppose,expect等动词引起的宾语从句中，有时谓语尽管是否定意义，却不用否定形式，而将think 等动词变为否定形式。例：I dont think you are right. (我认为你做的不对)在许多带有复合宾语的句子中，that引导的宾语从句经常移到句子的后面，而用it做形式宾语。例：We think it wrong that he told a lie to everyone (我认为他向每一个人撒谎是错误的)B,由连词if、 whether 引导的表示“是否”的宾语从句。Whether,if 在从句中不做句子的成分，一般情况下，whether和if 可以替换。例：I dont know if/whether he will come tomorrow.The teacher asked if/whether we had finished the experiment.在介词后面的宾语从句中不用if引导例：Everything depends on whether we have enough money。l宾语从句中有or not时不用if引导.例：I dont know whether the movie star will come or not.和不定式连用作宾语时不用if引导.例：Whether to go there or not hasnt been decided.C,由wh-引导的宾语从句。连接代词who,whom,whose,what,which,和连接副词when,where,why,how 等连接的宾语从句，它们在句中即有连接从句的作用，又在句中充当句子的成分。例：Do you know which film they are talking about? (which做定语)I dont know where he lives. (where 做地点状语)二，宾语从句的语序，宾语从句从句的语序必须是陈述语序，即连接词+主语+谓语+其他成分例：I believe that they will come soon.He asked me whether I was a teacher.They wanted to know what they can do for us.二，宾语从句的时态。宾语从句的时态受主句的限制，既：主句是一般现在时态，从句根据实际情况而定。主句是一般过去时态，从句用相应的过去的时态。如果从句的动作发生在主句之前，则从句要用过去完成时态。例：1. She says that she is a student.She said that she was a student.1. She says that she will fly to Japan in a week.She said that she would fly to Japan in a week.如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一般现在时态。例：The teacher said that the earth goes round the sun.He told me that Japan is an island country.Could you tell me是用来征询对方的意见，语气委婉，并不表示过去。例：Could you tell me when we will visit the Histury Museum注意事项：由陈述句变成宾语从句时，要注意人称的变化。例：She said: “I have been to England before.”She said that she had been to England before.宾语从句与简单句的交换。由连接代词和连接副词引导的宾语从句，如果宾语从句的主语和主句的主语是同一个人时，可以用“疑问词+不定式”做宾语的简单句结构。例：I dont know what I should do next.I dont know what to do next.DO SOME EXERCISES:1Can you see_1. what hes reading B. what is he reading2. what does he read D. he reads what2Does Jack come from Japan? Do you know?(合并成一个句子)Do you know_Jack _from Japanwhat was the matter D. what the matter wasThe keys: 1 A.2 if,comes6版本五关系代词1. 1.that指代人或物，在句中作主语或宾语2. 2.which指代物，在句中作主语或宾语（特殊：指代前面的一整件事3. 3.who 、whom指代人，分别作主语和宾语4. 由关系代词whose引导的定语从句：whose用作名词的限定语，whose后一定有名词。由关系副词when、where、why引导的定语从句：如果句子中不缺少主语和宾语时，则考虑用关系副词。1、when在从句中作时间状语。when（on which）2、where在从句中作地点状语。where（in which）3、why在从句中作原因状语。why（for which）注意1、用which不用that的情况：（1）“逗号”后不用that用which。（2）介词后不用that用which2、用that不用which的情况：（1）先行词为不定代词（各种thing 例：something。nothing）（2）先行词前有最高级、序数词、the only 、the very 等修饰时（3）先行词既有人又有物时。3、特殊情况：（1）way（方式，方法）+（1）that（2）in which（3）什么都用例：I hit way （that/in which）you speak to your parents（2）当句子中不缺主语、宾语时，出现“point、condition、stage、case”等词后用where。7宾语从句的定义置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句。有些形容词（afraid,sure,glad等）之后也可以带宾语从句。8宾语从句中引导词的用法在复合句中作主句的宾语，引导词有：连词：that (that 常可省略),whether, if代词：who, whose, what ,which副词：when ,where, how, why 等。that引导的宾语从句（在非正式场合that可以省略）可跟that从句做宾语的动词有：say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。例句：The boy believes that he will travel through space to other planets.注意事项：当主句谓语动词是 think, believe, suppose, expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。例句：I dont think it is right for him to treat you like that.在以下情况中that不能省略1. 当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.2. 当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.3. 当that从句是双宾语中的直接宾语时，that不可省。例句：I cant tell him that his mother died.注意事项：许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。例句：I find it necessary that we should do the homework on time.由whether,if 引导的宾语从句由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。一般说来，在宾语从句中whether与if可以互换使用，但在特殊情况下if与whether是不能互换的。例句：I wonder whether(if) they will come to our party.只能用whether，不能用if引导的宾语从句1. 在带to的不定式前例句：We decided whether to walk there.2. 在介词的后面例句：Im thinking of whether we should go to see the film.3. 在动词后面的宾语从句时例句：We discussed whether we had a sports meeting next week4. 直接与or not连用时例句：I cant say whethe
