谁能给一些定语从句的练习?我现在上初中

1、The people ( ) you were talking to are Russians.
A that B who C which D whom
答案是A.
that用作介词to的宾语,常省略.介词to
紧随动词之后,不能放在that前面.
2、The man ( ) I saw is called Bob.
A whom B whose C who D which
答案是C.
who用作宾语,代替whom,常省略,此处也可用that .
3、I'd like a room ( ) window looks out over the sea.

whose 也可指物,在从句中用作定语
4、This is the man ( ) I referred to.

答案是C.
whom用作介词to的宾语,介词紧跟动词之后.
