疑问词与疑问代词的区别（介词与疑问代词）
疑问词与疑问代词的区别（介词与疑问代词）T：聪明！比如：S: 哦！明白了！疑问副词引导的特殊疑问句，句尾不可能有介词，因为介词后必须加宾语，疑问副词不能作宾语。When were you born？=which year were you born in？=In which year were you born？
S: 学生 T:老师
S: 老师，With whom did he go?这个句子是特殊疑问句吧！特殊疑问词前面都可以加介词吗？觉得好奇怪！
T:这是whom引导的特殊疑问句。介词with也可以放到句尾，此时whom可以换作who; with提到句首时，只能用宾格whom who不与介词搭配使用。
根据句意需要，有时介词可以放在特殊疑问代词前面；有时疑问副词都可以用介词加疑问代词的形式来表达。比如：
When were you born？=
which year were you born in？=
In which year were you born？
S: 哦！明白了！疑问副词引导的特殊疑问句，句尾不可能有介词，因为介词后必须加宾语，疑问副词不能作宾语。
T：聪明！比如：
Where have you been?
What place have you been to?
To what place have you been?
你去过什么地方？
S:老师， 疑问副词都可以换做介词加疑问代词来提问吗？
T: 当然！比如：
where =in/at/ to which /what place
when = in which year/on which day
why = for what purpose/reason
how = in what way/manner
这是牛津字典中对四个疑问副词的英语释义。
S: 哦！终于明白：为什么定语从句中，关系副词等于介词加关系代词了。
T: 其原理是相通的。
S: 老师，那疑问代词what which whose作定语时，所修饰的名词有单复数的限制吗？
T: 没有限制，可数不可数名词都可以。比如：
What newspaper do you prefer?
Which books are on the desk?
Whose pen is this?
S: 明白！
T: 练一练吧！
翻译：1. 我应该在哪一站下车？
2. 这本书是关于什么的？
3. 你住在几楼？
S: 1.At which station should I get off?
2. What is this book about?或
About what is this book?
3. Which floor do you live on?或
On which floor do you live?
T: 很好！
