牛津译林版英语九上初中宾语从句专项语法讲解
初中英语宾语从句专项语法讲解在复合句中用作宾语的从句叫宾语从句。
1.语序无论主句是陈述句还是疑问句,宾语从句都必须使用陈述语序,即“主句+连词+宾语从句(主语+谓语+……)”句式。
根据连接词在从句中所担任的不同成分,可分为以下四种:1)连接词+谓语。
连接词在从句中作主语。
常见的连接词有:who,what,which等。
如:Could you tell me who knows the answer,please?你能告诉我谁知道答案吗?The small children don't know what is in their stockings.这些小孩子不知道袜子里有什么东西?2)连接词+名词+谓语。
连接词在从句中作主语的定语。
常见的连接词有:whose,what,which,how many,how much等。
如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。
The teacher asked us how many people there were in the room.老师问我们房间里有多少人。
3)连接词+主语+谓语。
连接词在从句中作宾语、状语或表语。
常见的连接词有:who (m),what,which,how many,how much,when,why,how,where,if /whether(在句中不充当任何成分)等。
如:He hasn't decided if he'll go on a trip to Wuxi.他还没决定是否去无锡旅行。
Could you tell me what I should do with the money ?你能告诉我我如何处理这笔钱吗?4)连接词+名词+主语+谓语。
连接词在从句中作宾语或表语的定语。
常见的连接词有:what,which,how many,how much,how等。
如:Do you know which class he is in ?你知道他在哪个班吗?She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。
2.连接词1)当由陈述句充当宾语从句时,用that引导,that无词义,在口语或非正式文体中常省略。
如:He said that he could finish his work before supper.他说他会在晚饭前完成工作。
2)当由一般疑问句充当宾语从句时,用if或whether引导,意为“是否”。
如:I don't know if /whether he still lives here after so many years.我不知道这么多年后他是否还住在这儿。
但在下列情况下只能用whether:①在具有选择意义,又有or或or not时,尤其是直接与or not连用时,往往用whether (if…or not也可以使用)。
如:Let me know whether /if he will come or not.(=Let me know whether or not he will come)让我知道他是否能来。
I don't know whether /if he does any washing or not.(=I don't know whether or not he does any washing.)我不知道他洗不洗衣服。
I wonder whether we stay or whether we go.我不知道我们是去还是留。
②在介词之后用whether。
如:I'm interested in whether he likes English.我关心的是他是否喜欢英语。
We're thinking about whether we can finish the work on time.我们正在考虑是否能按时完成这项工作。
I worry about whether I hurt her feelings.我担心是否伤了她的感情。
③在不定式前用whether。
如:He hasn't decided whether to visit the old man.他尚未决定是否拜访那位老人。
I don't know whether to go.我不知去否。
He hasn't decided whether to go by bus or by train.他还未决定是乘公共汽车去还是坐火车去。
④whether置于句首时,不能换用if。
如:Whether this is true or not,I can't say.这是否真的我说不上来。
⑤引导主语从句和表语从句时宜用whether。
如:Whether she will come or not is still a question.她是否能来还是个问题。
The question is whether we can catch the bus.问题是我们能否赶上公共汽车。
⑥若用if会引起歧义时,则用whether。
如:Please let me know if you like the book.可理解为:a.Please let me know whether you like the book.请告诉我你是否喜欢这本书。
b.If you like the book,please let me know.你如果喜欢这本书,请告诉我。
3)如果宾语从句原来是特殊疑问句,只需用原来的特殊疑问词引导。
如:Could you tell me why you were late for the meeting this morning?你能告诉我今天早上你为什么开会迟到吗?3.时态含宾语从句的复合句,主、从句谓语动词的时态呼应应包括以下三点内容:1)如果主句的谓语动词是一般现在时,从句的谓语动词可根据需要,选用相应的任何时态。
如:I don't know when he will come back.我不知道他将何时回来。
He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。
2)如果主句的谓语动词是过去时,宾语从句的谓语动词只可根据需要,选用过去时态即一般过去时、过去进行时、过去将来时或过去完成时的某一种形式。
如:①The children didn't know who he was.孩子们不知道他是谁。
②He asked his father how it happened.他问他父亲这件事是如何发生的。
3)如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等,不管主句用什么时态,从句时态都用一般现在时。
如:The teacher said that the earth goes round the sun.老师说地球绕着太阳转。
4.注意:if和when既可以引导宾语从句,也可以引导状语从句,应注意它们在两种从句中的意思和用法的不同。
if和when引导宾语从句时,分别意为“是否”和“何时”,其时态应和主句时态相呼应;它们引导状语从句时,意思分别为“如果,假如”和“当……时候”,当主句时态是一般将来时时,其时态用一般现在时。
它们常常放在含有状语从句和宾语从句的题干中进行综合考查。
如:—Do you know when he will come back tomorrow ?你知道他明天什么时候回来吗?—Sorry,I don't know.When he comes back,I'll tell you.对不起,不知道。
当他回来了,我将告诉你。
—I don't know if he will come.我不知道他是否会来。
—He will come if it doesn't rain.如果不下雨,他会来的。
简化宾语从句常用六法同学们常会遇到把含有宾语从句的复合句转化为简单句,使其与原句意思相同(或相近)的试题。
下面就介绍几种常用的简化宾语从句的方法:方法一:当主句谓语动词是hope,decide,wish,choose,agree,promise等,且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。
例如:Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon.We decided that we would help him. →We decided to help him.方法二:当主句谓语动词是know,learn,remember,forget,tell等动词,且主句主语与从句主语一致时,宾语从句可简化为“疑问词+不定式”结构。
例如:She has forgotten how she can open the window. →She has forgotten how to open the window.注:当主句谓语动词是tell,ask,show,teach等动词,且后带双宾语,从句主语和间接宾语一致时,宾语从句可简化为“疑问词+不定式”结构。
例如:Could you tell me how I can get to the station?→Could you tell me how to get to the station?方法三:当主句的谓语动词是order(命令),require(需要)等时,如果主句和从句的主语不一致,宾语从句可简化为“名词(代词)+不定式”结构。
例如:The headmaster ordered tha t we should start at once. → The headmaster ordered us to start at once.方法四:某些动词后的宾语从句,可以用介词加动名词(短语)等其他形式简化。
例如:He insisted that he should go with us. →He insisted on going with us.The poor boy doesn’t know when and where he was born. →The poor boy doesn’t know the time and the place of his birth.方法五:某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。

牛津译林版九年级英语上学期语法知识点讲解--宾语从句(一)
牛津译林版九年级英语上学期语法知识点讲解--宾语从句(一)一.基本用法在主从复合句中,从句做宾语就叫宾语从句。
这类从句的结构为:主句+引导词+从句,从句中始终用陈述语序。
(一)that引导的宾语从句1.that 在宾语从句中只起连接作用,并不做任何句子成分,其本身也没有实际意义。
在口语或非正式问题中常常省略,省略之后并不影响原句性质和意义。
I think(that)blue is better than pink.我认为蓝色比粉色好。
2.that引导的宾语从句,其主句的谓语动词多为say,know,hear,see,hope,wish,think等。
有时系动词he后加sorry,glad,sure,afraid,happy,worried等形容词时,其后也可接that引导的宾语从句。
3.宾语从句的时态宾语从句的时态主要有以下三种情况。
(1)如果主句是一般现在时或一般将来时,从句可根据需要仍用原句中的各种时态。
I know that he watched TV last night.我知道他昨天晚上看电视了。
(2)如果主句是一般过去时,宾语从句应用过去某种时态形式,即一般过去时,过去进行时,过去将来时和过去完成时等。
He told me that they would go to the park next week.他告诉我他们下周将去公园。
(3)如果从句是表示自然现象、客观真理等,不管主句用什么时态,从句一定要用一般现在时。
The teacher said that the light travels faster than the sound.老师说光比声音传播得快(二)if/whether引导的宾语从句宾语从句中,if和whether都可以做引导词,意为“是否”,在一般情况下可以互换。
If多用于口语或非正式文体中,whether多用于比较正式的文体中。
二、特殊用法1.一般来说,that引导宾语从句时常常可以省略,但当一个句子中有两个或更多的由that 引导的宾语从句并列时,仅可以省略第一个连接词that,后面的连接词that则不能省略。
译林版英语九年级上册_语法透析:宾语从句
语法透析:宾语从句一、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:1. 连接代词who, whom, whose, what, which在句中充当主语、宾语、定语或者表语。
如:Do you know which film they are talking about? (which做定语)2. 连接副词when, where, why, how在句中充当状语。
如:I don’t know where he lives. (where 做地点状语)二、宾语从句的语序,宾语从句的语序必须是陈述语序,既:连接代词/副词+主语+谓语+其他成分。
例:I don’t know what they are looking for.Could you tell me when the train will leave?Can you image what kind of man he is?三、宾语从句的时态。
宾语从句的时态受主句的限制,①主句是一般现在时态,从句根据实际情况而定。
②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。
③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.2)She says that she will fly to Japan in a week.She said that she would fly to Japan in a week.3)She says that she has finished her homework already.She said that she had finished her homework already.4)She says that she can sing a song in English.She said that she could sing a song in English.【注意】1.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。

E.g. He said (that) he wanted to stay at home.The boy was interested in whatever he saw here. 那孩子对在那里看到的任何事物都感兴趣。
I am sure (that) he will succeed.三、宾语从句的种类根据引导宾语从句的不同连词,宾语从句可分为三类。
四、用法详解1、引导宾语从句的连词和代词选择1)由that引导的宾语从句。
That只有语法作用,没有实在的意义,在口语和非正式文体中可以省略。
1.He said (that)he wanted to stay at home.2.She doesn’t know (that)she is seriously ill.3.I am sure (that)he will succeed.2)由连接代词who,whom,whose,what,which和连接副词when,where,why,how引导的宾语从句。

1.Do you know who (whom)they are waiting for?2.He asked whose handwriting was the best.3.Can you tell me where the No.3 bus stop is?4.I don’t know why the train is late.3 )由if或whether引导的宾语从句。

四、否定转移 在含有宾语从句的主从复合句中,当主句的主语为第一人称,谓 语动词是think,believe,guess,suppose等时,要将从句的否定 词转移到主句中,即主句的谓语动词用否定式,宾语从句的谓语动 词用肯定式。 eg:(5)Idon’tthinkhewillcomewithyou. 注意:这种句子在其后接附加问句时,要特别小心。 eg:(6)Idon’tbelievehehasfinishedthework, ________? hashe (7)HeknewwhyJimwasn’tatschool, didn’the ___________? 解析:例6,当主句的主语为第一人称时,附加问句的主语由宾 语从句的主语充当。 例7,如果主句的主语非第一人称时,则附加问句的主语 由主句的主语充当。
5.Couldyoutellme______________________?(我该怎么去车站) howIcangettothestation whythetrainislate 6.Wouldyoutellme_________________ ?(为什么火车迟到了)

9A 1-3单元中考语法总结一、知识引入How many grammar points have we studied from Unit1 to Unit3?二、知识讲解Unit1 宾语从句在句子中起宾语作用的从句叫作宾语从句。
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。
1.that引导的宾语从句陈述句充当宾语从句时,由that引导。
that在从句中不充当成分,只起连接作用,在非正式英语中可以省略。
如:He said (that) he would help me with my Physics.他说他将帮助我学习物理。
I hope that yellow can bring me success.我希望黄色能带给我成功。
形容词certain,sure和glad等后面也可以跟宾语从句。
如:I'm sure that Millie will come to our party.我肯定米莉将会来参加我们的聚会。
当主句的主语是第一人称I/we,谓语动词是think,believe,suppose,expect和imagine等时,后面宾语从句的否定词要前移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式。
如:I don't think I know you.我想我并不认识你。
I don't believe he will come.我相信他不会来。
注意:若主句的谓语动词为hope,宾语从句中的否定词不能前移。
如:I hope you weren't ill.我希望你没有生病。
若主句的谓语动词是find,make和think等,后面又带有复合宾语时,常用it作形式宾语,而将实际的宾语从句置于宾语补足语之后。
如:I think it necessary that we will have a meeting tomorrow.我想我们明天开个会是有必要的。
