疑问代词有who,whom,whose,what和which。它们一般放在句首,构成特殊疑问句。如:Who teaches you English?谁教你们的英语?
注意:
1.who是主格,whom是宾格,口语中who可以代替whom。如:
—Who is she?
—She is my sister.
Whom /Who are you looking for?
2.whose可以用作定语、表语等。如:
—Whose is this bag?
—It's mine.
3.what与which都有选择的意思,which用于在特定范围内的人或物中进行选择,而what则没有此限制。如:
Which do you like best,pears,apples or oranges?
What class are you in?
注:(关系代词我们放在定语从句中讲解)
