Pattern Practice When 引导时间状语从句时表示“当。。。的时候”，即可指时间段也可指时间点，从句中即可用延续性动词又可用非延续性动词，且动作即可和主句的动作同时发生又可在主句的动作之前或之后发生。
例如：We were swimming in the lake when suddenly the storm started.while引导时间状语从句时表示“当。。。的时候”
如果它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导时间状语从句和主句中的谓语的动词必须是延续性动词；
如果主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词。
这两种情况下从句和主句的谓语动词必须是延续性动词。例如：
I’m going to the post office.
While you’re there, can you get me some stamps?
as引导时间状语从句时表示“当。。。时，一边。。。一边。。。” ，侧重表示两个动作同时发生﹙包括一个主语同时进行两个动作﹚，或者一种动作随着另一种动作的变化而变化。
例如：He jumps as he goes along.
As it grew darker, it became colder.三者的区别：
㈠while从句中动词必须为延续性动词，不论其主句动词的延续性与否。
㈡若主、从句表示两个同时进行的持续性动作,且强调主句表示的动作延续到从句所指的整个时间，通常要用while.
Don’t talk while you’re eating.
I kept silent while he has writing.
但是，若主从句所表示的两个同时进行的动作含
有“一边。。。一边。。。”之意思，通常用as
She sang as she went along.㈢表示“每当。。。的时候” ﹙暗示一种规律性﹚，
一般要用when.
It’s cold when it snows.
He smiles when you praise him.
㈣若主从句所表示的动作不是同时发生，而是有先
后顺序时，一般要用when.
I will go home when he comes back.
㈤when可用作并列连词，表示“这时﹙突然﹚’’;
while 也可以用作并列连词，表示“而” “却” ﹙表示对比﹚；
但as则没有类似用法。

㈥when和 while后可接现在分词﹑介词短语﹑形容词等构成省略句，但as一般不这样用。
When ﹙While﹚ reading, he fell asleep.
When ﹙While﹚ in trouble, ask her for help.
