二、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. 到哪里去弄到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。
注:连接副词why 后不能不定式,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。

  • 连接副词的句法特征:
    所谓连接代词和副词,实际上就是我们以前学过的疑问代词和副词,如who, whose, whom, what, which, when,where, why,how以及由how构成的词组。
    1.连接副词起对等连接词的作用,连接两个句子或子句,如:
    however, so, then,moreover,concequencely,hence,also,besides,,otherwise,therefore,thus等。
    I feel a bit tired. However, I can hold on.我有点累了,但我能坚持下去。
    They talked about it for hours. Finally, they decided to go。他们对此商量了好几个小时,最后他们决定去。

    2.连接副词通常位于子句的句首,有的也可位于句中。
    They talked about it for hours. Finally, they decided to go。他们对此商量了好几个小时,最后他们决定去。
    finally作为连接副词,放在句子的句首。
    I have never been to Wales. I, therefore, don't know much about it.我从未去过威尔斯,因此我对它知道的不多。
    therefore作为连接副词,位于句子的句中。

    3.有些连接副词的含义彼此相同或相近,在使用时可以互相替换,而不会改变原句的含义。
    The weather was cold. Therefore(Thus), we stayed home.天气寒冷,因此我们待在家里。
    therefore和thus的含义相近,因而也可以互相替换。

    在应用时要注意以下两点:
    一是它们在构成疑问句时叫疑问词,引导宾语从句时称作引导词。
    一是它们和that不一样,在从句中有含义,担任相关的句子成分,所以不能省略,另外,它们须放在宾语从句之首,宾语从句必须是陈述句结构。

  • 引导名词性从句的连接词可分为三类:
    连接词:that, whether, if, as if, as though(不充当从句的任何成分,但绝不能省略)
    连接代词:what, whatever, who, whoever, whom, whomever, whose, which, whichever.
    连接副词:when, whenever, where, wherever, how, however, why

    不可省略的连词:
    1. 介词后的连词
    2. 引导主语从句和同位语从句的连词不可省略。
    That she was chosen made us very happy.
    We heard the news that our team had won.
    大部分连接词引导的主语从句都可以置于句末,用 it充当形式主语。
    It is not important who will go.
    It is still unknown which team will win the match.

  • 考点名称:动词短语

    • 动词短语:
      由动词和动短语成,或以动词为中心,功能同动词的短语叫动词短语,动词短语是动词的一种固定搭配形式,动词短语的搭配可分为下列四种基本类型。

    • 动词短语搭配形式:
      1.动词+副词
      ①作及物动词,例: 
      He brought up his children strictly.   
      从以上的例句中可以看出,在“动词+副词”的词组中宾语位置有两种情况:
      宾语如是名词,则可置于副词后面,亦可置于动词和副词之间。
      而如果宾语是代词,只能置于动词后面,即动词和副词之间。   
      ②作不及物动词,例:    
      Something unexpected has turned up. 出现了令人意外的情况。(turn up=appear)   
      ③既可作及物动词又可作不及物动词,例:   
      The barrel of gunpowder blew up.(不及物)火药桶爆炸了。   
      The soldiers blew up the bridge.(及物)士兵们把桥炸毁了。

      2.动词+介词 
      动词与介词构成的词组在词义上相当于一个及物动词,宾语总是在介词后面,例:
      I don’t much care for television.我不很喜欢电视。(care for=like)

      3.动词+副词+介词
      在这类动词短语中,动词、副词、介词紧密结合,是动副词组和动介词组的合成体,词义上相当于一个及物动词。
      它兼有以上两类短语动词的特点,但宾语总是位于介词之后,例: 
      We must work hard to make up for lost time.我们必须努力工作来弥补失去的时间。(make up for=compensate)

      4.动词+名词
      这类动词短语中的常见动词是have,take,give,make等,
      后面的名词通常是从动词转化而来的动作名词,并表达了短语动词的真正意义,例:    
      Let’s have another try.让我们再试一下。(have a try=v.try)  

      5.动词+名词+介词    
      这类动词短语只用作及物动词。名词前可加形容词说明程度,宾语总是位于介词之后,
       例:Keep an eye on the baby while I am out.我不在家时请照看一下小孩子。   

      6.be+形容词(包括过去分词作形容词)+介词    
      这类动词短语也相当于及物动词,宾语位于介词后面,形容词是短语动词的真正词义,
      例:I know he is slow at understanding,but you have to be patient with him. 我知道他理解力差,但你得对他耐心些。

    • 动词短语与短语动词:
      <?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />一、短语动词
      (1)短语动词常常是两个词(一个动词+一个副词性小品)构成,如:wake up , get up ,turn out 等。

      (2)同一个动词后面可以有不同的副词性小品词,构成不同意义的短语动词。如:He turn on the radio .Bob turned out smiling.

      (3)短语动词用法普遍,尤其在非正式语言中:

      我们可以说 He awoke late the following morning .但这太正式了。

      我们通常说 He woke up late the following morning .


      短语动词的类型

      Here is a page from Mr Jones` diary :

      Monday ,February 5th.

      *有些短语动词不带宾语:

      The car broke down .Cigarette prices are going up.

      *多数主短语动词可以带宾语,宾语通常在副词性小品词的前或后:

      动词+副词性小品词+宾语 动词+宾语+副词性小品词

      I rang up a garage. I rang a garage up.

      如果宾语较长,则通常放在副词之后:

      I filled in an application form.(不说 I filled an application form in .)
