宾语从句

  宾语从句的概念:

  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。

  宾语从句的用法:

  1、宾语从句的引导词:

  宾语从句通常由连词that和whether(if)、连接代词或连接副词以及关系代词型what引导:

  如:We believe that he is honest. 我们相信他是诚实的。

  I don't know whether he'll arrive in time. 我不知道他是否能及时到。

  I don't know who(m) you mean. 我不知道你指谁。

  He asked why he had to go alone. 他问他为什么必须一个人去。

  Please tell me which you like. 告诉我你喜欢哪一个。

  She has got what she wanted. 她要的东西得到了。

  注:有时介词后可接跟一个宾语从句(但介词后通常不接that和if引导的宾语从句):

  如:From what you say, he is right. 根据你所说的,他是对的。

  有极个别介词(如but,except)可接that引导的宾语从句:

  如:She remembered nothing about him except that his hair was black. 她对他什么都不记得,只记得他的头发是黑的。

  2、宾语从句与形式宾语it:

  当宾语从句后跟有宾语补足语时,通常在宾语从句处使用形式宾语it,而将真正的宾语从句移至句末:

  如:I think it best that you should stay here. 我认为你最好住这儿。

  He hasn't made it known when he is going to get married. 他还没宣布他何时结婚。

  3、连词that的省略问题:

  引导宾语从句的连词that通常可以省略:

  如:She said(that) she would come to the meeting. 她说过要来开会的。

  I promise you(that) I will be there. 我答应你我会去。

  注:有时为了强调,that引导的宾语从句可位于句首,此时that不可省略:

  如:That she is a good girl I know. 她是一个好姑娘,我是知道的。

  4、宾语从句与否定转移当动词think, believe, suppose, expect, imagine后接一个表示否定意义的宾语从句时,其否定通常转移到主语:

  如:I don't suppose that it is true. 我认为那不是真的。

  I don't imagine that he will come. 我想他不会

  使用宾语从句特别注意:

  一、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。

  如: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?

  二、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。

  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。

  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。

  如:The teacher told his class that light travels faster than sound.

  三、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.
