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 isnt 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: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:Ive lived here as long as 20 years.
我在此处居住长达20年之久.
