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。
  例句：I don’t think it is right for him to treat you like that.
  
  2.在以下情况中that不能省略
  a.当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。
  例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.
  b.当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。
  例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
  c.当that从句是双宾语中的直接宾语时，that不可省。
  例句：I can’t tell him that his mother died.
  d.注:许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。
  例句：I find it necessary that we should do the homework on time.
  
  （二）由whether,if 引导的宾语从句
  1.由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。
  一般说来，在宾语从句中whether与if可以互换使用，但在特殊情况下if与whether是不能互换的。
  例句：I wonder whether(if) they will come to our party.
