  • 动名词
  • 宾语从句

动名词概念:

动名词是一种兼有动词和名词特征的非限定动词。它可以支配宾语,也能被副词修饰,动名词有时态和语态的变化。


现在分词和动名词用法比较:

动词的-ing形式包括现在分词和动名词两种形式。他们的句法功能如下:
动词的-ing形式如果作句子的主语或者宾语时,应该是动名词形式;如果作补语或者状语时,应该是现在分词形式。那么作表语或者定语的动名词和现在分词又该怎样区分呢?
1、动名词与现在分词作表语时的比较:
(1)动名词作表语说明主语的内容,回答what的问题;现在分词作表语相当于形容词作表语,说明主语的性质、特征等,回答how的问题。
如:One of the best exercises is swimming. 游泳是最好的运动项目之一。 
        What pleases him most is bathing in the sea. 最使他高兴的事是在海中沐浴。 
        The situation both at home and abroad is very in-spiring. 国内外的形势都很鼓舞人心。
        The color is pleasing to the eye. 颜色悦目。
(2)动名词作表语,表语和主语几乎处于同等地位,可以互换位置,其句意不变;现在分词作表语,表语和主语则不能互换位置。
如:Our work is serving the people.
      (=Serving the people is our work.)我们的工作是为人民服务。 
        The news was disappointing. 那消息令人失望。
(3)作表语的现在分词前可以用very,quite,rather,greatly等副词修饰,而动名词则不可以。
如:What he said was very encouraging. 他的话很鼓舞人心。
        Our goal is realizing the four modernizations in the near future. 我们的目标是在不久的将来实现四个现代化。
(4)现在分词与形容词一样可以和more,the most构成形容词的比较级和最高级,而动名词则不可以。
如:The story is the most fascinating. 那个故事最迷人。
(5)作表语用的现在分词除了和be连用以外,还可以和其它的系动词连用;而作表语的动名词则通常只能和be连用。
如:His speech seems inspiring.他的演讲似乎很鼓舞人心。
        His interest is writing for the news papers. 他的爱好是给报社写文章。
(6)有些用作表语的现在分词已经形容词化了。常见的有:exciting,moving,inspiring,missing,interesting,disappointing等。
2、动名词与现在分词作定语时的比较:
(1)动名词作定语时,表示它所修饰的名词的性能和用途,和它所修饰的名词在逻辑上没有主谓关系;
现在分词作定语时,表示它所修饰的名词正在进行的动作,和它所修饰的名词在逻辑上有主谓关系,常可以扩展成一个定语从句。
如:a swimming girl=a girl who is swimming 一个在游泳的姑娘
        a walking stick=a stick that is used for walking 一根拐杖
(2)现在分词作定语有时可以后置,而动名词则通常只能放在它所修饰的名词之前。
如:The girl wearing glasses is one of his students. 戴眼镜的那个女孩是他的一个学生。
        I bought some reading materials. 我买了一些阅读材料。


 动名词的用法:

1、作主语:
例如:Fighting broke out between the South and the North. 南方与北方开战了。 
2、作宾语:  
a. 有些动词可以用动名词作宾语。
例如:admit承认 appreciate感激 avoid避免 complete完成 consider认为 delay耽误 deny否认 detest讨厌 endure忍受 enjoy喜欢 escape逃脱 fancy想象 finish完成 imagine想象 mind介意 miss想念 postpone推迟 practice训练 recall回忆 resent讨厌 resume继续 resist抵抗 risk冒险 suggest建议 face面对 include包括 stand忍受 understand理解 forgive宽恕 keep继续
例如:Would you mind turning down your radio a little, please? 你把收音机音量调小一点,好吗?
        The squirrel was lucky that it just missed being caught. 这松鼠幸运得很,刚逃避了被逮住的厄运。     
b. 有些结构后面可以用动名词作宾语或其他成分。
例如:admit to  prefer...to   burst out   keep on   insist on   count on   set about   put off   be good at   take up   give up   be successful in   be used to   lead to  devote oneself to   object to  stick to  no good   no use be fond of   look forward to  be proud of   be busy   can't help  be tired of   be capable of   be afraid of   think of
3、作表语,对主语说明、解释:
例如:Her job is washing, cleaning and taking care of the children. 她的工作是洗刷、清扫和照顾孩子。
比较:She is washing, cleaning and taking care of the children.
4、作定语,一般表示所修饰名词事物的用途:
例如:a writing desk=a desk for writing 写字台
            a swimming pool=a pool swimming 游泳池
有些动名词作定语,与所修饰的名词关系比较复杂。
例如:boiling point=a temperature point at which something begins to boil 沸点
            a walking tractor=a tractor which a driver can operate while he or she is walking behind it 手扶拖拉机


动名词知识体系:

 


动名词与不定式用法对比:

 


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.
