宾语从句讲解

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 right.

l在think,believe, suppose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 don’t think you are right. (我认为你做的不对)

l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 don’t know if/whether he will come tomorrow.

The teacher asked if/whether we had finished the experiment.

l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 don’t know whether the movie star will come or not.

l和不定式连用作宾语时不用if引导.

例:Whether to go there or not hasn’t 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 don’t 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,既连接词+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.

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.

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.

She asked me: “Do you like maths”

She asked me if I liked maths.

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 don’t know what I should do next.

I con’t know what to do next.

He didn’t know where he would live.

He didn’t know where to live.

宾语从句用法详解

宾语从句用法详解 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)

Can you tell me how to get to the station, 六、宾语从句的语序。 宾语从句的语序都用陈述句语序(即正常的主谓语序) He says that Jim will miss a lot of lessons .

宾语从句结构和用法总结详解

一.宾语从句的含义 在主句中做宾语的从句叫做宾语从句。 如:She knewthat the teacher had seen the film. “that the teacher had seen the film”做knew 的宾语,同时又是由连接词that 引导的从句,所以它叫做宾语从句。 二.宾语从句的分类 1.动词宾语从句:顾名思义,它是位于动词后面的宾语从句。 如:He askedwhose handwriting was the best in our class.他问我们班上谁的书法最好。 2.介词宾语从句:顾名思义,它是位于介词后面的宾语从句。 如:I agree withwhat you said just now.我同意你刚才说的话。 3.形容词宾语从句:顾名思义,它是位于形容词后面的宾语从句。 如:I am afraidthat I will be late.恐怕我要迟到了。 三.引导名词性从句的连接词 1.that:没有含义,在宾语从句中不做成分 2.whether/if:表示是否,在宾语从句中不做成分。 I don't knowif /whether he still lives here after so many years. 我不知道这么多年后,他是否还住在这里。 3.连接代词:what, which, who, whom, whose(在宾语从句中做主、宾、表和定语) 连接副词:where, when, how, why(在宾语从句中做状语) The small children don't knowwhat is in their stockings.(what 在宾语从句中做主语) Could you tell mewhy you were late for the meeting this morning?(why 在宾语从句中做原因状语) 四.在做宾语从句的题目时应注意两点 1.时态: ①当主句是现在时态时,宾语从句可以根据需要使用任何时态。 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当主句是过去时态时,宾语从句必须是一种过去的时态。 She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。 He said that he could finish his work before supper.他说他会在晚饭前完成工作。 ③当表示客观事实或普遍真理的句子做宾语从句时,任何时候都用一般现在时。 The teacher said that the earth goes round the sun.老师说过地球绕着太阳转。 2.语序:任何从句都使用陈述句语序,宾语从句当然也不例外。

Do you know what he likes? 3)连接副词主要有when,where,why,how,whenever,wherever,however等。 He didn’t 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。 宾语从句--动宾从句 大多数及物动词都可以带宾语从句。 部分“动词+副词”结构也可以带宾语从句。 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 one’s mind(下决心)、keep in mind(牢记) 可运用形式宾语it代替的宾语从句 ①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。 ②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,te ach,tell 宾语从句--介宾从句 用whether之类的介词宾语从句。 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。 宾语从句--形容词+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;

宾语从句,全方位多角度解析!

宾语从句,全方位多角度解析! 一.宾语从句的含义 在主句中做宾语的从句叫做宾语从句。 如:She knew that the teacher had seen the film. “that the teacher had seen the film”做 knew 的宾语,同时又是由连接词 that 引导的从句,所以它叫做宾语从句。 二.宾语从句的分类 1.动词宾语从句:顾名思义,它是位于动词后面的宾语从句。 如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。 2.介词宾语从句:顾名思义,它是位于介词后面的宾语从句。 如:I agree with what you said just now.我同意你刚才说的话。 3.形容词宾语从句:顾名思义,它是位于形容词后面的宾语从句。 如:I am afraid that I will be late. 恐怕我要迟到了。 三.引导名词性从句的连接词

1.that:没有含义,在宾语从句中不做成分 2.whether/if:表示是否,在宾语从句中不做成分。 I don't know if /whether he still lives here after so many years. 我不知道这么多年后,他是否还住在这里。 3.连接代词:what, which, who, whom, whose(在宾语从句中做主、宾、表和定语) 连接副词:where, when, how, why(在宾语从句中做状语) The small children don't know what is in their stockings.(what 在宾语从句中做主语) Could you tell me why you were late for the meeting this morning?(why 在宾语从句中做原因状语) 四.在做宾语从句的题目时应注意两点 1.时态: ①当主句是现在时态时,宾语从句可以根据需要使用任何时态。 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当主句是过去时态时,宾语从句必须是一种过去的时态。

宾语从句讲解

宾语从句是主从复合句的一种。宾语从句当中的从句在全句中作宾语。 例句:I know him。I know who she is 结构:主语+谓语+引导词+简单句(其它) 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,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?The small children don't know what is in their stockings.I don't know which belongs to my father. 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.The teacher asked us how many people there were in the room. 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)。如:He hasn't decided if he'll go on a trip to Wuxi.Could you tell me what I should do with the money ? 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 ? he asked me if I knew whose pen it was. 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. 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. 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 whethe 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
