1 While he was getting off the bus,he fell and hurt himself
2 When he fell and hurt himself,he was getting off the bus
3 He was getting off the bus when he fell and hurt himself
4 He fell and hurt himself while he was getting off the bus.
5 As he got off the bus, he fell and hurt himself
6 He fell and hurt himself as he got off the bus.
简单易懂,没有长篇大论,不过你需要比较和记住.
while+延续性动词，when+延续或非延续性动词都可以
例句：When I was having breadfast, someone knocked at the door.
When I was leaving my room, the postman arrived.
While I was doing my homework, my mum came back.
