一、when与while的区别
在when引导的时间状语从句中，谓语动词可以是延续性动词，也可以是非延续性动词。而在while引导的时间状语从句中，谓语动词必须是延续性动词。
We were talking when the teacher came in.
我们正在交谈，这时老师进来了。
They arrived when/while we were having dinner.
当我们正在吃晚饭时，他们到了。
二、 when引导的时间状语从句与主句的时态
I was walking in the street when the accident happened.
我正在街上散步，这时这起交通事故发生了。
The accident happened when I was walking in the street.

[总结]
能够延续的动词用过去进行时，不能延续的动词用一般过去时。
主句 when从句
过去进行时 一般过去时
一般过去时 过去进行时
三、 while 引导的时间状语从句与主句的时态
I saw the accident while I was walking on the road.
当我正在街上散步时，我看见了这起交通事故。

[总结]
当强调两个动作同时进行时，主句和while从句都用过去进行时。

三、归纳

An emergency landing
US Airways Flight 1549 took off as usual from an airport in New York. But after only three minutes, the plane was hit by a large number of birds. The pilot, Chesley Sullenberger, had to make a quick decision to avoid a terrible disaster. He and the crew kept calm and he carefully made an emergency landing on the Hudson River. All the passengers left the plane safely. When reporters interviewed him, he said, “ I was just doing my job.”
