（1）Where do you come from? （2）Where are you travelling to?
请问上面的 where 是什么词?
有一派英语语法学家认为，副词不能受介词的支配，因此，把上面的where列为疑问代词。另一派英语语法学家则认为，副词作介词的宾语是很常见的，因而，也是很正常的。例如，over there, in here, out of here, from abroad, since then, till now, until recently, for ever。因此，把上面的where看作是疑问副词。本书采用的是后一观点。让我们考察一些实例：
-
Where did John call from? 约翰从哪儿打来的电话?
-
Where did you buy that jacket from? 你从哪儿买的那件夹克衫？
-
Where was she walking to? 她往哪儿走?
[附注]在疑问句中,Where ... to 中 to 常常可以省略,Where ... from 中的 from 却是不可省略的。但是,在简略的疑问句中,where to 中的 to 是不可省略的,见 where 中的例 4。where
They have no idea at all ____. A. where he has gone B. where did he go C. which place has he gone D. where has he gone(全国高考)
我知道答案为A。但是我不能说明where从句是个什么类型的从句。
wh-从句充当介词宾语从句时,其前的介词 of, about, as to 常常省略。在上句中可以看作是在 where 从句之前省略了 of, 见 idea, prepositions, wh-clause 。类例：
When you find anything, make a note where it's found, and do a drawing in your notebook. (where 从句前省略了 of) 你们发现任何东西,都要记下是在哪儿发现的,并在笔记本上画上草图。
