从属连词宾语从句

考点名称：从属连词

• 从属连词：
  这种连词是用以引导名词性从句定语从句和状语从句的，由从属连词所引导的句子叫从句,而含有从句的句子叫作复合句。

• 从属连词可分为三大类：
  1、that （无词义，不做成分）
  if，whether （表达是否的意义，但不做句子成分）
  2、连接代词：who，whom，whose，what，which，whatever, whoever, whichever（有词义，在句子中可作主语、表语、宾语）
  3、连接副词：when，where，why，how，how many，how long，how far，however，whenever，wherever （有词义，作从句的状语）

  用法：
  从结构上说，英语连接词分两大类：并列连词和从属连词。
  
  并列连词连接两个或两个以上地位平等的字、词组或分句。例如：
  (1) Air and water are indispensable to me. 　　
  (2) She likes going out with friends or playing outdoor games. 　　
  (3) Most workers have a good income, so they look very happy. 　　
  
  从属连词连接两个或两个以上的分句，形成复杂句中的从属分句。例如： 　　
  (4) He said that he did not want to go . 　　
  (5) Many things have happened since I last saw him. 　　
  (6) You may come if you want to. 　　
  
  从属连词用来连接各种从句。
  until(till)直到，在用until表达时间状语的句子中，主句中的动词是要十分小心去选择的。
  如动词是持续行动词，它要用肯定句，如：
  I studied hard until 12 o'clock last night.
  如果动词是瞬间截止性动词，则要用否定句，如:
  He didn't go to bed until his mother came back.
  由since,for,by,before, 来引导的时间状语从句。
  since 引导的时间状语是动作的开始时间，如:
  I have studied English since 1990.
  而by引导的时间状语通常是动作的结束时间，如：
  I had learned 25 English songs by the end of last term.

• 从属连词语法分类：
  

  种类	语法作用	连词举例
  从属连词	引导原因状语从句	Because, since
  	引导条件状语从句	If, unless, as long as
  	引导目的状语从句	So that
  	引导结果状语从句	So…that
  	引导方式状语从句	As, just as, as if
  	引导让步状语从句	Though, although, even though, no matter what, however, no matter how, whoever, no matter who, wherever, no matter where
  	引导比较状语从句	As…as, not so…as, than, less…than, the more…the more
  	引导名词性从句	Who, whom, whose, which, that, when, where, why

考点名称：宾语从句

• 宾语从句：
  在句子中起宾语作用的从句叫做宾语从句。
  宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。
  宾语从句连接代词主要有：
  who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever 等。

• 宾语从句的特点:
  1.宾语从句可以作及物动词、介词及形容词的宾语。
  2.宾语从句的语序一律用陈述句语序。
  3.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。
  4.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。
  5.如果从句太长，可以用形式宾语it.

  宾语从句的时态:
  1.主句是一般现在时，从句根据实际情况使用任何时态。
  例句：The headmaster hopes everything goes well.
  2.主句是过去时态，从句须用过去时态的某种形式。
  例句：She was sorry that she hadn’t finished her work on time.
  3.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。
  例句：The teacher told his class that light travels faster than sound.
  4. 如果从句的动作发生在主句之前，则从句要用过去完成时态。 
  
  宾语从句的语序:
  A. 宾语从句必须用陈述语序。 　　
  False: He is wondering when can he finish this difficult job. 　　
  Right: He is wondering when he can finish this difficult job.
  B. 有时候可以用it 作形式宾语，而把真正的宾语从句放在后面。 　　　
  Bad: I thought that he could finish this　job in just two hours impossible. 　　
  Good: I thought it impossible that he could finish this job in just two hours.　 
  C. 带有宾语从句的复合句的否定形式一般是否定主句。
  Bad: I think he doesn’t like the English teacher. 　　
  Good: I don’t think he likes the English teacher. 
  D.  主句一般过去时态，从句也要用过去时态。
  False: He wanted to know why he is crying in the corner. 　　
  Right: He wanted to know why he was crying in the corner

  宾语从句的否定转移:
  主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等。
  并且主句的主语是第一人称而且为一般现在时，从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致。
  I don’t think he will come to my party.而不能说成I think he won’t come to my party.
  我认为他不会来我的舞会.
  I don’t believe that man is killed by Jim,is he?
  我认为那个人不是Jim所杀的,是不是?
  如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式。
  We find that he never listens to the teacher carefully,does he?
  我们发现他从来不仔细听老师讲课，是不是?

• 宾语从句中引导词的用法比较
  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
  代词：who, whose, what ,which
  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）
  1.可跟that从句做宾语的动词有：
  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。
