关于英语定语从句的题目
用适当的关系词that which who whom whose where when why填空
1.the flat in ____ we live was built in the 1960s.
2.the room ____Windows face south is my bedroom.
3.have you received the e-mail _____ i sent to you yesterday?
4.didn't you see the man with _____ i talked just now?

一 which,live是不及物动词,所有通常和in连用表示住在什么地方 捋直了就是we live in the flat .这里的which在句子里做in 的宾语,所有用which ----------
二 whose 这个比较好判断了,windows是the room的,所有选whose表示...的
三 that/which或者不填都可以 明显从句补充完整是i sent the-email to you yesterday
