定语从句
1． I've read many stories of Lei Feng，________this is the most touching one.
A．who B．of which
C．of whom D．that
答案 B [考查定语从句用法。句意：我读过很多雷锋的故事，其中这个故事最令人感动。先行词为stories，代入定语从句后为：This is the most touching one of the_stories.由此可见先行词在定语从句中作介词of的宾语，先行词(stories)表示“物”，故排除C项。]
2．Reading books，________takes the reader to other worlds，is a wonderful way to enjoy life.
A．that B．what
C．as D．which
答案 D [考查非限制性定语从句。句意：读书是一种享受生活的好方法，它把读者带到其他的世界中。先行词是reading books，代入定语从句后为：Reading books takes the reader to other worlds.先行词在定语从句中作主语，且该从句为非限制性定语从句，故用which引导。]
3．This was returned because the person________this letter was addressed had died three
years ago.
A．to whom B．to which
