As作连词引导时间状语从句时,着重强调主句和从句中的动作同时发生,并且从句通常放在主句之前。归纳起来有下列两种情况:
1)状语从句的谓语动词是持续性动词,从句时态常用进行时态。
如: ①As he Was waiting,he suddenly heard a voice from above……
②As Bethune and the other doctors were climbing the hills,they could see the enemy entering the village in the valley below.
2)状语从句的谓语动词是终止性动词,从句时态常用一般时态。
如: ①As she stood there,she heard the first bell.
②As they looked up,they saw another cloud coming towards them.
③As they watched.it came nearer and nearer.

.as soon as引导时间状语从句当主句用一般过去时时，从句中用一般过去时或过去完成时。
例：晚会刚一开始他就离开了。
as soon as the party began/had begun he left.
he left as soon as the party began/had begun.(位于主句前后均可)
例：他一听到那个消息就晕倒了。
as soon as he heard/had heard the news, he fainted.
he fainted as soon as he heard/had heard the news.
2.as soon as 可以表将来的事：这时主句用一般将来时，从句用一般现在。(主将从现)
例：我一见到他就会告诉他这个消息。
as soon as i see him i will tell him the news.
i will tell him the news as soon as i see him.(位于主句前后均可)
我一到北京就会给你打电话。
i will call you as soon as i arrive beijing.
as soon as i arrive beijing i will call you.
我一看到他就会告诉。
i will tell him as soon as i see him.
as soon as i see him i will tell him.
当主句用一般将来时时，可以用一般现在时代替一般将来时
