what和which的区别:在名词性从句中,what可以当从句的主语,宾语,表语,而which很少用于名词性从句。在定语从句中,只能用which,that充当从句的主语、宾语、表语、定语,不能用what。
what和which有什么区别
一、修饰名词:
当用作定语修饰其后接名词时,which用于有范围限制的场合,what用于没有范围限制,侧重于种类的场合。如:
Which color do you like, black or white?
Which is bigger, the sun or the earth?
What color is your car?
二、单独使用,后面不加名词:
当其后不接名词时,which和what的用法区别依然是:用于有范围限制的场合,what用于没有范围限制,侧重于种类的场合。如:
What would you like for dinner?
I'd like tomatoes, cucumbers, lettuce and onions.
We have tomatoes, cucumbers and onions.
Which would you like for dinner?
I'd like some tomatoes.
三、与else和of短语连用时:
由于what提问的事物没有范围限制,所以其后可以跟else,但一般不跟表示特定范围的of短语。而which提问的事物有范围限制,所以其后一般不接else,但却常与表特定范围的of短语连用。如:
What else have you bought?
Which of these dictionaries is yours?
What和which引导从句
1。在名词性从句中,what可以当从句的主语,宾语,表语,而which很少用于名词性从句,如在名词性从句出现,它表示的是~那一个~即已确定的几个人或物中的~那一个~,往往在从句中当定语,后面要跟一个名词,如果上文刚出现了几个确定的名词,which后可省略名词,计时它当主语,宾语,表语,但它不象what一样表示某物一,某物二,,而是表示~那一个~例:
What I want to sell is my house。
I have three houses,I have to sell one,but I don`t know which to sell。
2。在定语从句中,只能用which,that当从句的主,宾,表,定,不能用,what,例:
The thing which/that I want to sell is my house。
