  • 连接副词
  • 宾语从句

连接副词的概念:

连接副词可分为两类,一类是用于连接句子或从句,常见的有therefore, otherwise, however, moreover, still, thus, meanwhile等,另一类是用于引导从句或不定式,主要有when, why, where, how等。 例如:We all tried our best; however, we lost the game. 
            Tell me when we shall leave. 
            I do not know how to find him.


连接副词的分类

连接副词可分为两类,一类是用于连接句子或从句,常见的有therefore, besides, otherwise, however, moreover, still, thus, meanwhile等;
另一类是用于引导从句或不定式,主要的有when, why, where, how等。

连接句子或从句的连接副词:

其性质类似于并列连词,使用时其前通常用分号或句号;若其前用逗号,则通常带有并列连词(如and):
如:I don't like it; besides, it's too expensive. 我不喜欢它,而且也太贵了。 
        We all tried our best; however, we lost the game./ We all tried our best. However, we lost the game. 我们都已尽了最大的努力,不过我们还是输了。
注意:有的连接副词(如however等)后通常有逗号与句子的其他成分隔开。另外,有的这类副词还可位于句中或句末:
如:Peter is our youngest child, and we have three others besides. 彼昨是我们最小的孩子,我们另外还有三个孩子。
        He may, however, come later. 不过,他也许一会儿就到。
        We all tried out best. We lost the game, however.我 们都已尽了最大的努力,不过我们还是输了。

引导从句和不定式的连接副词:

用于引导从句(名词性从句)或不定式的连接副词主要有when, why, where, how等:
如:Tell me when we shall leave./ Tell me when to leave. 告诉我什么时候离开。
        I don't know how I can find him./ I don't know how to find him. 我不知道如何找到他。
       Where we can get the money is just our problem./ Where to get the money is just our problem. 到哪里去弄这笔钱正是我们头痛的事。
        That's why he speaks English so well. 那就是他为什么英语讲得这么好的原因。
:连接副词why后不能接不定式,如可说:I don't know why I must leave. (我不知道我为什么必须离开),但不能说:I don't know why to leave.

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。
: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。
: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.
