较长的动作可以作为短暂事件发生时的背景。
理解要点
while 引出正在进行的动作,常用过去进行时。when 可以引出一般过去时中的短暂事件。时间从句放在句首时,后面用逗号。
例句
- The lights went out while we were eating.我们吃饭时灯灭了。
- While the children were drawing, the bell rang.孩子们画画时,铃响了。

朗读使用设备上的英语合成语音,质量和可用性因设备而异;它不会评估发音。
设备上没有可用的英语语音,你仍然可以阅读例句。
注意事项
并非所有过去事件都用 while 引出;突然到达通常用 when。
