过去进行时表示在过去某一时刻或某一时间段正在进行的动作，可以和
when,
while,
as
引导的过去时间状语从句连用。
1)
When
I
met
him,
he
was
playing
with
his
son.
我遇见他时，他正在和他儿子玩。
2)
While
I
was

当我在做作业时，我妹妹在听音乐。
3)
As
he
was
lying
in
bed,
the
telephone
rang.
他躺在床上时，电话铃响了。
本课我们主要来分析when和while从句与过去进行时连用的情况。
when和while引导的时间状语从句区别
I：
动词
时间
状语
when引导的时间状语从句
while引导的时间状语从句
终止性动词或延续性动词
延续性动词
指时间点或时间段
时间段
when和while引导的时间状语从句区别Ⅱ：
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。
例如：
We
were
talking
when
the
teacher
came
in.?
我们正在讲话，老师(突然)进来了。
这句话也可以用while来表达，但与when表达有细微的区别，请注意体会：
While
we
were
talking,
the
teacher
came
in.
我们正在讲话的时候，老师进来了。(只表示老师进来的事实，不强调突然性。)
当主句和从句的动作都是延续性的或同时发生的，两句都用过去进行时的时候，通常用while引导从句。
1)
They
were
singing
while
we
were
dancing.?
他们在唱歌，我们在跳舞。
2)
They
were
reading
while
we
were
writing.
他们在读书，我们在写字。
