有。as可以引导时间状语从句，此时as译作“当……时候”，可以放在主句之前，也可以放在主句之后。as可以引导原因状语从句，此时as译作“因为，由于”，一般放在句首，语气较弱，较口语化。
as long as 是介词短语，一般接句子
1.As long as arranging the time reasonably,we are sure to benefit more from recreational activities.(08年6月CET-4里的.)
其中的arranging ，并不是说该词后加动词ing形式，arranging 是句子arranging the time reasonably中的部分，是独立主格形式，它不能看作是as long as后加动名词。
2.as long as it isn&39;t boring就是一个例子，而As long as do not rain!实际上是省略句，省略了it ，完整的用法是As long as it do not rain!至于什么时候省略，随着英语学习的加深，自然能够形成这种语感。
as long as其实有三个意思：
1) 只要 = so long as = while
如：You&39;ll succeed as long as you work hard.
只要你好好学习,你就会成功的.
2）(长度上)和...一样长 / 长至...(程度)/ 长达...
如：The room is as long as 10 meters.
这个房间长达10米.
3）(时间上)和...一样久 / 久至.../ 长达...
如：I&39;ve lived here as long as 20 years.
我在此处居住长达20年之久.
as long as有三个用法:
1.During the time that (在这段时间):I&39;ll stay as long as you need me.
2.Since (既然) :As long as you&39;ve offered,I accept.
3.On the condition that (条件是):I will cooperate as long as I am notified on time.
