5.Isleptsoundly.Itrainedcatsanddogs.n.电力供应adv.（睡觉）酣畅地辨析：when&whilewhen既可以表示一个时间点，也可以表示一个时间段。从句的动词既可以是短暂性动词（如：arrive,start,finish,open等），也可以是延续性动词（如：stay,live,work等）。主句动作可以发生在从句动作的“瞬间”，也可以是同时或先后。while主要表示一个时间段（持续的、进行的一段时间）。从句的动词必须是延续性动词（如：be,stay,work,sleep等）或表示状态的词。从句常用进行时态。强调主句和从句动作“同时持续”发生，或在从句动作的“持续期间内”发生主句动作。例句：

I

waswatching

TV

when

thelight

wentout.

我正在看电视，这时灯灭了。（“灯灭”是短暂性动词）例句：
