“Hearing the news,they all jumped with joy.”能不能改成 “When hearing the news, they all jumped with joy.”？ 但是 为什么 可以说“When leaving the airport,she waved again and again.” 4楼 什么是 “为了表示明确时间”？
不能 when they heard the news they all jumped with joy 才对

When they heard the news, they all jumped with joy。 只能这么改。 when后面跟的是一个完整的句子。

为了表示明确的时间，可以在分成词的前面加when,while 等连词 While waiting for the train,I had a long talk with her while waiting for the train = While we were waiting for the train You must be careful when crossing the street when crossing the street =when you are crossing the street
