作为疑问代词,它们一般用于疑问句(比如where are you from?你来自哪里?)。
其他用法则视具体情况而定,作为关系代词在定语从句中:He is the only one in our class ,who can attend the swimming game.(他就是我们班唯一能参加游泳比赛的人),前面不加逗号是限制性定语从句,加逗号的是非限制性的。
如:She loves her hometown very much,where she spend her happy childhood.(她非常爱她的家乡,在那里她度过了欢快的童年)。两者意义上的区别不大。
另作为名词性从句的引导词,后可以接不定式或一般陈述句,如:I don't know what to do next(我不知道接下来做什么),What he said is wrong(他说的话不对)。

who which where属于关系代词,在从句中可作主语或宾语,后面跟句子。
定语从句关键在于选对关系词,关系词的选择要依据2种情况来定:
1、先行词(被定语从句修饰的词)
先行词是“物”可能用which,that,whose,where,when,why等
先行词是“人”可能用who,whom,that,whose等
2、关系词在定语从句中所担任的句子成分
① 先行词是人且关系词在从句中作主语,用who/that
He is a man who never breaks his word. 他是个从不食言的人
② 先行词是人且关系词在从句中作宾语,用whom/that
He is the man whom I think to be nice. 我认为他是个很不错的人
③ 先行词是物且关系词在定语从句中作主语,用that,which.
The dog that/ which won the race is John’s. 比赛获胜的那头狗是约翰的
④ 先行词是物且关系词在从句中作宾语,用that,which,也可以省略
The letter(that /which) I received yesterday was from my brother.我昨天收到的那封信是我兄弟寄来的。
⑤ 先行词是“人”或“物”,关系词在从句中作定语表所属关系,用whose引导定语从句
例:That is a book whose cover is blue.那是一本封面是蓝色的书.(先行词是“物”book,所属关系词whose在定语从句中做定语修饰cover)
⑥ 先行词是时间、地点或理由的名词,则用关系副词引导定语从句
I don't know the reason why he was late. 我不知道他为什么迟到
定语从句分为限定性定语从句和非限定性定语从句。加逗号的是非限定性定语从句
限定性定语从句
例:I like the book which he bought yesterday.(我喜欢他昨天买的书)
非限定性定语从句:
例:He has just come back from New York, which is a very big city in the United States。(他刚从纽约回来,那是美国的一座大城市)
