实际上，when 从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。

When I got to the airport, the guests had left. 当我赶到飞机场时，客人们已经离开了。

When t he manager comes here for a visit next week, I’ll talk with him about this.下周，经理来这参观时，我会和他谈谈此事。

2、相比于when 来说，while 从句的侧重点就不一样了。

while 从句的侧重点在于描述动作正在发生的状态，它的意思是：当while 事件正在发生的时候，另一件事如何如何。

所以，while 从句一般用的是正在进行时。

While my wife was reading the newspaper, I was watching TV.当妻子正在看报纸的时候，我正在看电视。

While Jim was mending his bike, Lin Tao came to see him.正当吉姆修自行车时，林涛来看他。

While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。

as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。

但与while 从句不同的是，as 从句用的一般不用正在进行时，而只是一般过去时。

as 从句一般可以翻译成“边……边……”As my mother sang those old songs, tears ran down her cheeks.当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。

The students took notes as they listened. 学生们边听课边做笔记。

如果从句动作和主句动作同时发生，并且从句动作为延续性动词时，when，while，as 可以互换使用。

When /While /As we were dancing, a stranger came in.当我们跳舞时，一位陌生人走了进来。

[dance 为延续性动词]When /While /As she was making a phone call, I was writing a letter.当她在打电话时，我正在写信。

[make为延续性动词]as, when 引导短暂性动作的动词。

例如：Just as / Just when / When I stopped my car, a man came up to me.我刹车后，有一个人向我走来。

5、当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或while。

例如：When you have finished your work, you may have a rest.干完活后，你可以休息一下。

6、从句表示“随时间推移”连词能用as，不用when 或while。

例如：As the day went on, the weather got worse.日子一天天过去，天气越变越坏。

Before是主句动作发生在从句的前面。

After表示主句动作发生在从句动作之后。

主句和从句的动作的时间关系正好与before引导的从句相反。

例如：It will be four days before they come back. 他们要过四天才能回来。
