一个英语小问题
You see the lightning the instant it happens,but you hear the thunder later
闪电发生的同时你会看到闪光,但过一会儿你才听到雷声
中间用连词,为什么这个连词不能是介词短语
就是 the instant为什么不能用 for the instant等前面有介词的介词短语

the instant (that)是短语,表示“一.就”,相当于as soon as,在这里引导状语从句.你说的for the instant,少见这种搭配,更不能引导状语从句.
其实学习英语等语言学,不象学数学物理,没必要深究,记下来就是了,记得多你也就会用了.
