介词与疑问词搭配的几种类型
■当提问使用含有动词+介词小品词的wh-疑问句时，通常把介词小品词放在句末：
Who(m) are you going with? 你同谁一起走?
What are you looking at? 你在看什么?
Where did you get that suit from? 你从哪儿买到那套衣服的?
How on earth can I get these shoes on? 我到底怎样才能把这双鞋子穿上呢?
■在非常正式的英语里，介词可以放在疑问词之前：
To whom should I apply for more information? 我应该向谁询问更多的情况?
In which hall will the recital be given? 独唱会在哪个厅里举行呢?
■在简略疑问句里介词跟在疑问词后面：
We’re off on holiday tomorrow. 一Where to? 我们明天动身去度假。——到哪儿去?
Will you beat these eggs for me? 一What with? 你替我搅拌这些鸡蛋好吗?——用什么搅拌?
I want to leave this parcel. 一Who for? 我想把这个包裹留下。——留给谁?
