问题描述：
Tom is waiting for his mother .就his mother进行提问 .这样做For whom is Tom waiting 对
答
将原来的陈述句改变后,这是一个比较常见的特殊疑问句,只用直接问Who is Tom waiting for?就可以了.
答
最标准的是：Whom is Tom waiting for?
答
一般不选用这种形式。
既然wait for是一个词组，就不要把它分开用嘛！
主语可以选用who或是whom.现代英语中一般不注意这一点了。
答
Who/whom is Tom waiting for?这样更好
答
Whom is Tom waiting for?
像“wait for”这种本来介词就连在动词后组成词组的,最好动词和介词不要分开
答
对
