时间状语
动词
when引导的时间状语从句
指时间点或时间段
终止性动词或延续性动词
while引导的时间状语从句
时间段
延续性动词
when和while引导的时间状语从句区别2：
由when引导的时间状语从句，若主句用过去进行时、从句用一般过去时，则表示一个动作正在进行的时候另一个动作（突然）发生了，强调后一动作发生的突然，但while在这种用法中并不强调突然性。
注意观察下面的句子：
zxxk
We
were
talking
when
the
teacher
came
in.?
我们正在讲话，老师（突然）进来了。
While
we
were
talking,
the
teacher
came
in.?
我们正在讲话的时候，老师进来了。
（只表明老师进来的事实，不强调突然性）
当主句和从句的动作都是延续的或同时发生的，两句都用过去进行时的时候，多用
while
引导。例如：
They
were
singing
while
we
were
dancing.?
他们在唱歌，我们在跳舞。
