宾语从句的用法篇(1):宾语从句用法详解
宾语从句用法详解核心提示：宾语从句是主从复合句中最常见的从句之一。 它作及物动词、介词或者某些形容词的宾语。由于宾语从句涉及到引导词、语序、时态等多方面的内容，所以宾语从句的用法一直是学习的重点难点。本文对宾语从句的用法进行了详尽讲解并附有例句，望对中学生朋友有所帮助。一.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。二.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。（一）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 don’t think it is right for him to treat you like that.在以下情况中that不能省略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. 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. 当that从句是双宾语中的直接宾语时，that不可省。例句：I can’t 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.（二）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引导的宾语从句在带to的不定式前例句：We decided whether to walk there. 在介词的后面例句：I’m thinking of whether we should go to see the film. 在动词后面的宾语从句时例句：We discussed whether we had a sports meeting next week 直接与or not连用时例句：I can’t say whether or not thet can come on time. 只能用if不能用whether引导的宾语从句if引导条件状语从句，意为“如果”例句：The students will go on a picnic if it is sunny. if引导否定概念的宾语从句时例句：He asked if I didn’t come to school yesterday. 引导状语从句even if（即使）和as if（好象）时例句：He talks as if he has known all about it. （三）连接代词和连接副词引导的宾语从句这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。用于这种结构的动词常常是：see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。英语中的连接代词有：who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。例句：Can you tell me whom you are waiting for?英语中的连接副词有：when,where,why,how，在句中担任状语的成分。例句：None of us knows where these new parts can be bought.三.宾语从句的语序宾语从句的语序是陈述句语序即：连接代词/副词+主语+谓语+其他成分。例句如下：I don’t know what they are looking for. Could you tell me when the train will leave? Can you imagine what kind of man he is? 四.宾语从句的时态主句是一般现在时，从句根据实际情况使用任何时态。例句：The headmaster hopes everything goes well. 主句是过去时态，从句须用过去时态的某种形式。例句：She was sorry that she hadn’t finished her work on time. 当宾语从句表示的是一个客观真理或者事实时，即使主句是过去时，从句也用一般现在时态。例句：The teacher told his class that light travels faster than sound. 五.宾语从句的特点宾语从句可以作及物动词、介词及形容词的宾语。 宾语从句的语序一律用陈述句语序。 连接词that引导宾语从句在句中无词义，不充当句子成份，多数情况下可以省略。 whether 和 if 都可引导宾语从句，但 whether后可紧跟or not；whether从句可作介词的宾语。 如果从句太长，可以用形式宾语it.
宾语从句的用法篇(2):英语宾语从句用法详解
英语宾语从句用法详解
初中英语分类练习
——宾语从句
复习目标：1、掌握引导宾语从句的各种连词
2、掌握宾语从句的语序——主句+连接词+主语+谓语
3、掌握宾语从句，主句与从句在时态上的呼应。
重点：语序和时态呼应
难点：语序和时态呼应；疑问词+不定式的转化；状语从句的辨析
一、 宾语从句的连接词：
1、 连词that，只起连接作用，在从句中不作句子成分，也无词汇意义，在口语中常被省略。
eg. He knew (that) he should work hard.
2、 连词if 、whether，它们起连接作用，在从句中不作句子成分，作“是否”解，在口语中多用if。
eg. Tom don’t know if/whether his grandpa liked the present.
He asked me whether or not I was coming.
一般情况下，if 和whether可以互换，但以下3种情况只能用whether：
①在不定式前：Whether to go there or not hasn’t been decided.
②在介词前：It depends on(依靠) whether it is going to rain.
③与or not连用：They are talking about whether to go there or not.
3、 连接代词who, whom, whose, what, which，连接副词when, where, why, how， 它们起连接作用，作句子成分，各有自己的意义。
eg. The teacher asked the new students which class he was in.
I wonder where he got so much money.
【注意】1、由连接代、副词引导的宾语从句可以和“疑问词+不定式”结构转化。
eg. I don’t know how I should do with the presents. è I don’t know how to do with the presents.
2、要注意区分判断由if、when引导的从句类型.
二、 宾语从句的语序：
宾语从句的语序是陈述语序，即“连接词+主语+谓语+其它成分”。特别强调：它的主语和谓语的语序是陈述语序，而不是疑问句的倒装结构。
Can you tell me who(m) do we have to see?(╳)
Can you tell me who(m) we have to see?( √)
The teacher asked the students what they were doing.(思考: what在从句中的成分)
陈述句变为宾语从句时,要注意人称和时态的变化,语序不变。 eg. She said, “I will leave a message on the desk.” à She said she would leave a message on the desk.
一般疑问句和特殊疑问句变为宾语从句时,也要注意人称和时态的变化,后面接陈述语序。Eg. “Where are the tickets?” I asked him. à I asked him where the tickets are.
三、 宾语从句的时态呼应：
宾语从句中谓语动词的时态，常常受到主句谓语时态的制约，此为时态呼应。如果主句谓语是一般现在时或将来时，从句谓语的时态不受限制；如果主句谓语的时态是一般过去时，从句一般要随着改为相应的过去时态（一般过去时、过去进行时、过去将来时、过去完成时）。
eg. I thought (that) you are free today. (╳)
I thought (that) you would be free today. ( √)
【注意】当宾语从句叙述的是客观真理时，不管主句谓语的时态如何，从句都用一般现在时。
eg. The teacher told us (that) the earth moves around the sun.
四、 其他需要说明的问题：
1、 标点由主句决定，如主句是陈述句、祈使句，则用句号；是疑问句则用问号。
eg. I heard she had been to the Great Wall. Can you tell me which bus I should take?
2、 要注意个别句子中主从句人称的一致。
五、 宾语从句和状语从句的区分：
eg. 1) I will go out tomorrow if it is fine.
2) I don’t know if the train has arrived.
句1中if引导的是状语从句。这个从句表示“条件”，修饰主句。整个句子的意思是如果明天天气好，我就出去。句2中if引导的是宾语从句，充当谓语动词don’t know的宾语。整个句子的意思是我不知道火车是否到达。
判断方法：
1、 可以从整个句式看。状语从句一般可以放在主句的前面或后面（个别除外），宾语从句只能放在主句谓语动词之后。
2、 从引导词看。if充当宾语从句的连接词时，相当于whether， 词义为“是否”，充当状语从句的连接词时，词义为“如果”。when充当宾语从句的连接词时，意为“什么时候”，充当状语从句的连接词时，意为“当……的时候”。
3、 从时态看。if和when作连接词时，引导宾语从句要注意：从句的谓语动词的时态应根据主句的时态作相应的变化。if和when充当从属连词时，引导条件和时间状语从句，若主句的谓语动词用一般将来时，则从句的时态应用一般现在时表示将来。
实战演练
一、例题选讲
例1
I don’t know ________ he will come or not.
A．
how
B．
whether
C．
weather
D．
when
答案：
B
提示：
在宾语从句中出现了or not，这里只能用whether。
第二题答案为B，根据题意问他们何时回来，所以要用when。
例2
Can you tell me ________they will come back?
A．
where
B．
when
C．
which
D．
who
答案：
B
提示：
根据题意问他们何时回来，所以要用when。
例3
Have you seen the doctor? He asked me. （两句并一句）
答案：
He asked me if / whether I had seen a doctor
提示：
是一般疑问句，连接词应为if / whether
例4
How can we get to the science museum? Could you tell us?（两句并一句）
答案：
Could you tell me how we can get to the science museum?
提示：
特殊疑问句，连接词就是它本身的特殊疑问词how，将情态动词can放在主语me之后，时态运用取决于主句。主句could you tell me是委婉语气，是一般现在时，所以从句是什么时态就用什么时态。
直接引语变间接引语
一、如何变人称：直接引语变间接引语时，如果从句中的主语是第一人称或被第一人称所修饰。从句中的人称要按照主句中主语的人称变化如：She said. "My brother wants to go with me. "→She said her brother wanted to go with her.
“直接引语变间接引语时，若从句中的主语及宾语是第二人称。或被第二人你所修饰。从句中的人称要跟引号外的主句的宾语一致。如果引号外的主句没有宾语。也可以用第一人称，如：He said to Kate. "How is your sister now?"→He asked Kate how her sister was then。
“直接引语变间接引语时。如果从句中的主语及宾语是第三人称或被第三人称所修饰从句中的人称一般不需要变化如：Mr Smith said。 "Jack is a good worker。"→Mr Smith said Jack was a good worker。
二、如何变时态：直接引语在改为间接引语时、时态需要做相应的调整。如果主句谓语动词为现在范畴的时态或一般将来时，则间接引语中的动词仍保持直接引语原来时态。如果主句谓语动词为过去时，间接引语中的动词时态按下列变化：（1） 一般现在时变为一般过去时（2） 现在进行时变为过去进行时（3） 一般将来时变为过去将来时（4） 现在完成时变为过去完成时（5） 一般过去时变为过去完成时（6） 过去完成时不变，仍为过去完成时要注意在以下几种情况：
（1） 如果直接引语是表示客观真理时，变为间接引语，一般现在时不改为一般过去时。如：The teacher said "The earth goes round the sun."→The teacher said that the earth goes round the sun.（2）直接引语中有具体的过去某年、某月、某日作状语，变为间接引语时，时态不变。如： He said to me, "I was born in 1973."→He told me that he was born in 1973.
(3)如果直接引语所述事实在当时和目前同样生效，变为间接宾语时，一般现在时不改为一般过去时。如：He said, "I"m a boy, not a girl."→He said that he is a boy ,not a girl.
(4) 直接引语如果是一般现在时。表示一种反复出现或习惯性的动作，变间接引语时，时态不变。如：The girl said, "I get up at six every morning."→The girl said that she gets up at six every morning.
(5)如果直接引语中含有since, when, while 引导的表示过去时间的状语从句，在变为间接引语时，只改变主句中的谓语动词，从句的一般过去时则不变。如：He said to me, "I have taught English since he came here ."→He told me that he had taught English since he came here.
(6)如果直接引语中含有情态动词 must, need, had better以及情态动词的过去式could, might, should, would,在变为间接引语时，这些情态动词没有时态的改变。例如：The teacher said to me . "You must pay more attention to your pronunciation." →The teacher told me that I must (have to ) pay more attention to my pronunciation.He said , "I could swim when I was only six ."→He said that he could swim when he was only six.
(7) 直接引语是过去进行时，时态不变。如：Jack said. "John, where were you going when I met you in the street?"→Jack asked John where he was going when he met him in the street。
三、如何变状语：直接引语变间接引语，状语变化有其内在规津，时间状语由“现在”改为“原来”（例：now变为then, yesterday。变为 the day before）地点状语，尤其表示方向性的，或用指示代词修饰的状语，由“此”改为“彼”（例：this 改为that),如：He said, "These books are mine." →He said those books were his.
四．如何变句型：①直接引语如果是陈述句，间接引语应改为由that引导的宾语从句。如：She said, "Our bus will arrive in five minutes."→She said that their bus would arrive in five minutes.
②直接引语如果是反意疑问句，选择疑问句或一般疑问句，间接引语应改为由whether或if引导的宾语从句.如：He said, "Can you swim, John?" →He asked John if he could swim."You have finished the homework, haven"t you?" my mother asked. →My mother asked me whether I had finished the homework."Do you go to school by bus or by bike?" →He asked me if I went to school by bus or by bike.
③直接引语如果是特殊问句，间接引语应该改为由疑问代词或疑问副词引导的宾语从句（宾语从句必须用陈述句语序）。She asked me, "When do they have their dinner?"→ She asked me when they had their dinner.
④直接引语如果是祈使句，间接引语应改为"tell(ask, order, beg等) sb (not) to do sth."句型。如："Don’t make any noise," she said to the children. →She told (ordered) the children not to make any noise. "Bring me a cup of tea, please," said she.→She asked him to bring her a cup of tea.
⑤直接引语如果是以“Let"s”开头的祈使句，变为间接引语时，通常用“suggest +动句词（或从句）。”如：He said, "Let’s go to the film." →He suggested going to the film.或He suggested that they should go to see the film.
引述别人的话有两种方式：一是使用引号引出人家的原话，这叫做直接引语；一是用自己的话把人家的话转述出来，这叫做间接引语。例如：John said, "I"m going to London with my father."约翰说："我要和父亲到伦敦去。"（引号内是直接引语）John said that he was going to London with his father. 约翰说，他要和他父亲去伦敦。（宾语从句是间接引语）五、由直接引语变为间接引语的几种情况：1． 直接引语是陈述句时间接引语为that引导的宾语从句（口语中that可以省略），主句的引述动词主要有say ,tell, repeat, explain, think等。He said , "You are younger than I."-"He said (that ) I was younger than him.
2.直接引语是疑问句时间接引语为陈述语序：主句的谓语动词say 改为ask,或改为wonder, do not know, want to know, be not sure, be puzzled等。（1） 一般疑问句或反意疑问句变为if (whether)引导的宾语从句。She said, "Do you often come here to read newspapers?"→She asked me if (或whether)I often went there to read newspapers.She asked me , "You have seen the film, haven"t you?"→She asked me whether(或if )I had seen the film.
（2） 选择疑问句变为whether….or 宾语从句。I asked him, "Will you stay at home or go to a film tonight?"→I asked him whether he would stay at home or go to a film that night.
(3)特殊疑问句变为由原来的疑问词引导的宾语从句。He asked , "Where do you live?"→He asked me where I lived.
3.直接引语是祈使句时间接引语为不定式，作ask , tell, beg, order, warn, advise等动词的宾语补足语（don"t 变为not ）.The teacher said to the boy, "Open the window."→The teacher told the boy to open the window.His father said to him , "Don"t leave the door open."→His father told him not to leave the door open.[注意]（1） 有些表示建议、提议、劝告或要求的祈使句，可以用suggest ,insist等动词 加以转述。例如：He said, "Let"s go to the theatre."→He suggested (our )going to the theatre.或He suggested that we(should) go to the theatre.(2) "Would you mind opening the window?" he asked.→He asked me to open the window."Why don"t you take a walk after supper?" he asked .→he advised me to take a walk after supper."Shall we listen to the music?" he asked.→He suggested listening to the music.
4.直接引语是感叹句时间接引语为what 或how 引导，也可以用that 引导。She said, "What a lovely day it is !"→She said what a lovely day it was .或She said that it was a lovely day.5.代词等一般地应作用相应的变化，变化方法见下表。

宾语从句的用法篇(3):英语语法速记口诀
英语口语
此生能遇见你，已然
幸福得一塌糊涂
Jimmy"s Note
吉米老师前言：.英语语法速记口诀
英语语法速记口诀
一、冠词基本用法
【速记口诀】
名词是秃子，常要戴帽子，
可数名词单，须用a或an，
辅音前用a，an在元音前，
若为特指时，则须用定冠，
复数不可数，泛指the不见，
碰到代词时，冠词均不现。
【妙语诠释】
冠词是中考必考的语法知识之一，也是中考考查的主要对象。以上口诀包括的意思有：①名词在一般情况下不单用，常常要和冠词连用;②表示不确指的可数名词单数前要用不定冠词a或an，确指时要用定冠词the;③如复数名词表示泛指，名词前有this，these，my，some等时就不用冠词。
二、名词单数变复数规则
【速记口诀】
单数变复数，规则要记住，
一般加s，特殊有几处：
【妙语诠释】
①大部分单数可数名词变为复数要加s，也就是单词如果以ch，sh，s，x等结尾)，则一般加es;②以o结尾的单词除了两人(negro，hero)两菜(tomato，potato)加es外，其余一般加s;③以f或fe结尾的单词一般是把f，fe变为ve再加s;④英语中还有些单词没有规则，需要特殊记忆，如child—children，mouse—mice，deer—deer，sheep—sheep，Chinese—Chinese，ox—oxen，man—men，woman—women，foot—feet，tooth—teeth。
三、名词所有格用法
【速记口诀】
名词所有格，表物是“谁的”，
若为生命词，加“’s”即可行，
词尾有s，仅把逗号择;
并列名词后，各自和共有，
前者分别加，后者最后加;
若为无生命词，of所有格，
前后须倒置，此是硬规则。
【妙语诠释】
①有生命的名词所有格一般加s，但如果名词以s结尾，则只加“’”;②并列名词所有格表示各自所有时，分别加“’s”，如果是共有，则只在最后名词加“’s”;③如果是无生命的名词则用of表示所有格，这里需要注意它们的顺序与汉语不同，A of B要翻译为B的A。
四、接不定式作宾语的动词
【速记口诀】
三个希望两答应，两个要求莫拒绝;
设法学会做决定，不要假装在选择。
【妙语诠释】
三个希望两答应：hope，wish，want，agree，promise
两个要求莫拒绝：demand，ask，refuse
设法学会做决定：manage，learn，decide
不要假装在选择：petend，choose
五、接动名词作宾语的动词
【速记口诀】
Mrs. P Black missed a beef bag. (布莱克夫人丢了一个牛肉袋。)想学习更多英语知识，请关注口袋英语aikoudaiyy
【妙语诠释】
该句话中每个字母代表了一个动词或短语，这些动词要求后面跟动名词作宾语。这些动词分别是：
M=mind，r=risk，s=succeed in，P=practice，B=be busy，l=look forward to，a=admit，c=can’t help，k=keep on，m=miss，i=insist on，s=suggest，s=stop，e=enjoy，d=delay，
a=avoid，b=be worth，a=advise，g=give up。
六、不定式作宾语补足语时省to的动词
【速记口诀】
一感，二听，三让，四看，半帮助
【妙语诠释】
一感：feel;二听：hear，listen to;三让：make，let，have;四看：see，notice，watch，ob-serve;半帮助：help。
七、形容词和副词比较等级用法
【速记口诀】
1. 比较级与最高级：两者比较than相连，三者比较the在前。
2.同级比较：同级比较用原形，as…as永不离;as…as加not，只言两者是同一，若是not so…as，后强前弱不看齐。
【妙语诠释】
①比较级通常和than连用，而最高级通常跟有定冠词the;②同级比较一般用as…as表示“与…一样”，这时谁强谁弱不能比较出来，而not so…as则表示后者比前者强，翻译为“不如……”。
八、反意疑问句用法
【速记口诀】
反意问句三要点，前后谓语正相反;
短句not如出现，必须缩写是习惯;
最后一点应注意，短句主语代词填。
【妙语诠释】
①反意疑问句的构成应该是“肯定的陈述句+否定的疑问”或“否定的陈述句+肯定的疑问”;②在短句中not必须与do，will，can等组成缩写形式;③在简短问句中，疑问句的主语必须是代词，而不能用名词形式。
九、感叹句用法
【速记口诀】
感叹句，并不难，what、how放句前;
强调名词用what，其余用how很简单。
【妙语诠释】
由what引导的感叹句一般修饰名词，而how引导的感叹句一般修饰形容词、副词或句子。
十、宾语从句用法
【速记口诀】
宾语从句须注意，几点事项应牢记。
一是关键引导词，不同句子词相异。
陈述句子用that;一般疑问是否(if，whether)替;特殊问句更好办，引导还用疑问词。
二是时态常变化，主句不同从句异。主句若为现在时，从句时态应看意;主句若为过去时，从句时态向前移。
三是语序要记清，从句永保陈述序。
【妙语诠释】
宾语从句应注意三点：①引导词，陈述句一般由that引导，这时的that可以省略;一般疑问句则由if或whe-ther引导;而特殊疑问句则由特殊疑问词引导。②时态，主句是现在时态，从句可用所需要的任何时态;但如果主句是过去时态，从句时态所表示时间一般往前移一个时间段。③语序，宾语从句永远要用陈述句顺序。
