问题描述：
A ufo flew over my head while I was waking toward the bus stop yesterday
A UFO flew over my head while I waswaking toward the bus stop yesterday为什么是 A UFO flew ,不是 A UFO was flying呢?while引导的时间状语从句不是主从句都用进行时吗?怎么这里不是?
答
A UFO【 flew 】over my head while I was walking toward the bus stop yesterday.
我们都知道【UFO】的速度是【了不起】的,不可能与【我I】这样的【步行walking】相提并论,你说是吗?所以【flew过去时】的动作【过去了、发生了】.
