as 和since两个单词都表示众所周知的,或显而易见的原因,但意思稍有些不同,
as表示正如....那样.
而since表示既然,,,,,
for表示推测原因,一般只能放在句中,如:
As you see , he is better than you at study.
Since everyone is here, let's begin.
It must have rained last night, for the ground is wet.

...呃,这么说吧,for后面加一段时间,例如 for two years
而since 后面是加一段时间再加 ago,或者加一个具体的时间,例如 since three years ago 或 since 1998
