what和which的區(qū)別:在名詞性從句中,what可以當(dāng)從句的主語,賓語,表語,而which很少用于名詞性從句。在定語從句中,只能用which,that充當(dāng)從句的主語、賓語、表語、定語,不能用what。
what和which有什么區(qū)別
一、修飾名詞:
當(dāng)用作定語修飾其后接名詞時(shí),which用于有范圍限制的場(chǎng)合,what用于沒有范圍限制,側(cè)重于種類的場(chǎng)合。如:
Which color do you like, black or white?
Which is bigger, the sun or the earth?
What color is your car?
二、單獨(dú)使用,后面不加名詞:
當(dāng)其后不接名詞時(shí),which和what的用法區(qū)別依然是:用于有范圍限制的場(chǎng)合,what用于沒有范圍限制,側(cè)重于種類的場(chǎng)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、與else和of短語連用時(shí):
由于what提問的事物沒有范圍限制,所以其后可以跟else,但一般不跟表示特定范圍的of短語。而which提問的事物有范圍限制,所以其后一般不接else,但卻常與表特定范圍的of短語連用。如:
What else have you bought?
Which of these dictionaries is yours?
What和which引導(dǎo)從句
1。在名詞性從句中,what可以當(dāng)從句的主語,賓語,表語,而which很少用于名詞性從句,如在名詞性從句出現(xiàn),它表示的是~那一個(gè)~即已確定的幾個(gè)人或物中的~那一個(gè)~,往往在從句中當(dāng)定語,后面要跟一個(gè)名詞,如果上文剛出現(xiàn)了幾個(gè)確定的名詞,which后可省略名詞,計(jì)時(shí)它當(dāng)主語,賓語,表語,但它不象what一樣表示某物一,某物二,,而是表示~那一個(gè)~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。在定語從句中,只能用which,that當(dāng)從句的主,賓,表,定,不能用,what,例:
The thing which/that I want to sell is my house。
