一、宾语从句用法详解
名词性从句在复合句中作谓语动词、非谓语动词、介词的宾语时被称为宾语从句。下面我就给大家带来宾语从句的基本用法详解,一起来看看吧。
宾语从句就是一个句子的宾语部分是由另一个句子来充当。宾语从句需要用引导词来引导。学好宾语从句,必须过“三关”。即引导词关、语序关、时态关。
引导宾语从句的引导词分为三类,即:
1)。That在从句中不充当任何成分,也无实义,只是起到连接的作用。
通常在say, think, wish, hope, see, believe, agree, expect, hear, feel等动词后加that,引导宾语从句。连词that在口语中常被省略。
如:He said that he was a student.
I thought that he was wrong.
☆注意:A)引导宾语从句的that常可以省略,但下列情况下不能省略。
(1)and连接两个或两个以上的宾语从句,除第一个从句中的that以外,后面从句中的 that不能省略。
如:I know(that) he is a good student and that he likes basketball.
(2)、that引导的宾语从句作介词宾语时,that不能省略。
如: I know nothing about him except that he is from the south.
(3)、主句谓语动词与that从句之间有插入语,that不可省略。
如:We decided, considering his age, that we would not let him do the job.
B)常这样用的动词有find,feel,consider,make,believe等。
如:He doesn’t want it to be known that he is going away.
C) think, believe, imagine, suppose, consider, expect, fancy,guess等表示主观看法或认识的动词,.
如:I don’t think he will come to my party.(而不能说成I think he won’t come to my party.) I don’t believe that he is a good student, is he?我认为他不是个好学生,不是吗? I don’t think you are right.
I don’t believe that they have finished their work.
比较:she believes that I am not a good student.
如:I don't know whether/if I should go to the party tomorrow.
注意:在以下情况中,只能用whether。
A)在动词不定式之前只能用whether
如:I can’t decide whether to stay.
B)在whether…… or not的固定搭配中,只能用whether。
如:I want to know whether she is a student or not.
如:His father is worried about whether he has lost his work.
3 A)疑问代词包括what,who, whom, which,whose, whoever, whatever, whichever等.。如: Do you know who(whom) they are waiting for?
I don't know what they want.
John told me which girl he liked most..
I want to know whose father that old man is.
I will give you whatever you want.
You can meet whoever you want to see.
You can choose whichever you like.
B)疑问副词包括when, where, how, why, whenever,wherever,however等。
如: Could you tell me how we can get to the station?
He told me when we should go to the airport.
I told him where he should go.
I don't know why he is so angry.
You can come whenever you are free.
You can go wherever you like.
4)另外:宾语从句可做动词宾语,介词宾语,及某些形容词甚至是副词的宾语.例如:
1、He said that he was a student.(that从句是said的宾语)
2、宾语从句作介词的宾语,常常有两种情况:
如:We are talking about where we should go.(疑问代词where从句作介词about的宾语) The teacher is quite satisfied with what you have done.(疑问代词what引导的宾语从句时介词with的宾语)
B)用that,whether引导的介词宾语从句
如:except,but,besides三个介词后常常可以见到that引导的宾语从句。 We are talking about whether we should go camping.
3、常常用来引导宾语从句的形容词有:sure, certain, glad, please, happy, sorry, afraid, satisfied, surprised。That常常可以省略。
如:I am sure(that) I will pass the exam.
Mary was pleased(that) she had passed the final exam..(that引导的宾语从句是形容词pleased的宾语)
4、I will find out where he has gone(where引导的宾语从句作副词out的宾语).
如:1、Tom said. He is reading a book.
→ Tom said that he was reading a book.
2、He asks me. Are they playing a game?
→ He asks me if/whether they are playing a game.(宾语从句,陈述语序)
3、Where is the hospital? He told me.
→ He told me Where the Hospital was.
4、I don't know who he is
宾语从句的时态受主句的限制,既:
如: I think he is a clever boy.
I think he has gone to Beijing.
I think he bought the book yesterday.
He said he would go to Beijing tomorrow.
He forgot whether he had locked the door.
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.
3、当宾语从句叙述的是客观事实、真理、自然现象、名言警句、谚语等,不管主句是什么时态,从句一律用一般现在时。
例: He told me that Japan is an island country.(客观事实)
二、宾语从句结构及用法
一、结构:主语 谓语 宾语(陈述语序)
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
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)
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.
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 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:
例句:We decided whether to walk there.
例句:I’m thinking of whether we should go to see the film.
例句:We discussed whether we had a sports meeting next week
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
(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、宾语从句的结构和用法
1、结构:主语 谓语 宾语(陈述语序)。
2、语序为v. 主语 谓语 由if,whether引导宾语从句,主句为现在时从句为任意时态。
3、例句:Thecityinthatshelivesisfaraway.
4、1)宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是)已构成固定搭配,其他介词后一般不接that引导的宾语从句。
5、*I promised that I would change the situation.
6、*All this is different from what American young people would say about friendship.
7、*He is certain that watching so much television is not good for children.
8、*This article is well-written except that it is a bit too long.
9、2)宾语从句后如有宾补,要用形式宾语it来代替,而把宾语从句移至宾补之后。
10、He has made it clear that he would not change his mind.
11、3)在think,believe,suppose,expect等动词后的宾语从句中,如果谓语是否定的,一般将否定词移至主句谓语上,宾语从句则变成肯定形式。
12、He didn't think that the money was well spent.
