when 的用法有很多,最常用的是be doing when 后加do,此时译为当什么时候在做什么事,强调的是when前面的动词.
而当when译为刚一.就.的时候有三种用法,分别是：1,had done when加从句 2,was doing when加从句 3,be about to do when加从句.强调的却是是后面的从句,很有意思的.
举个例子,I had just started my car when it began to rain.译为：我刚一发动了我的汽车,天就下雨了.很美的英语.

第一句是对的。
一般来说，长的那个动作用ing，瞬间的动作用-ed。
像talking on the phone就是长动作，went into a shop是瞬间的动作。
跟前后没有关系。
