  关系代词常在从句中担任主语、宾语或表语等成分;关系副词常在从句中担任状语。另外,在使用上面的这些关系词时,有几个问题值得我们注意:

  首先,只能用whether而不能用if的情况

  1)引导主语从句,例如:

  Whether we'll make a loan for the project has not been decided .

  (正确)我们是否要为这个项目还没有定下来。

  OR:It has not been decided whether we'll make a loan for the project . (正确)

  If we'll make a loan for the project has not been decided .(错误)

  OR:It has not been decided if we'll make a loan for the project . (错误)

  2)作介词的宾语,例如:

  I have no idea about whether I can raise the money for buying a car . (正确)

  我不知道我是否能为买车筹措到资金。

  I have no idea about if I can raise the money for buying a car . (错误)

  3)后接不定式 ,例如:

  He didn't know whether to go all himself first or wait for

  her here.(正确)他不知道是他自己先去还是在这儿等她。

  He didn't know if to go all himself or wait for her here . (错误)

  (4)后接or not ,例如:

  We wonder whether they'll come in time or not.(正确)

  我们担心他们会不会准时到。

  We wonder if they'll come in time or not . (错误)

  其次,what引导的名词从句表达的意思是"……所……的".这个"所怎么的"定义根据"从句谓语的动作意义"而定。例如:

  I don't understand what you said.我不理解你所说的话。

  What he needs is to practice more.他所需要的是勤于练习。

  Money is what she is really after.金钱是她所真正追求的东西。

  People have different ideas about what happiness means .

  人们对于幸福的含义有不同见解。

  最后,要了解 -ever = no matter ,用于表示强调,意为"无论……".也就是说:

  whatever = no matter what(无论什么)

  whoever = no matter who(无论谁)

  whichever = no matter which(无论那个)

  whenever =no matter when (无论何时)

  wherever = no matter where(无论何地)

  however = no matter how (无论怎样)

  A 主语从句

  用作主语的主谓结构称之为主语从句。例如:

  Whether he'll come or not remains a question .

  他是否会来依然是一个问题。

  Whoever says that is not allowed .

  无论谁这样说都是不允许的。

  That she reads English aloud every morning helps her a

  lot in the improvement of her English study .

  她每天早晨朗读英文对提高她的英语学习起了很大的作用。
