1.I had lived with them for as long as I could remember, but I was not really sad to leave.
2.You can go out,as long asyou promise to be back before eleven oclock.
老师，as long as+从句时，后面的状语状语是修饰形容词long吗，第一句long是名词吗，但找不到有名词词性，第二句as long as是怎么样理解剖析好，as+从句是修饰前面long，as long as....是整体作状语吗,as long as这个结构不是固定的某一种使用方法吗？
as long as 有两层意思：
1. 跟......一样长（指距离或时间长度）。比如：
This line is four times as long as that one. 这条线是那条线的四倍长。
You can keep my book as long as you like. 我的书你要借多长时间都随你的便。
网友的第一句，就是这个使用方法，说明居住时间之长，跟我记忆力所及一样：
I had lived with them for as long as I could remember, but I was not really sad to leave.
据我记忆所及，我和他们住在一块很长时间了，但我离开时并非非常难过。
去掉比较的部分则是如此：
I had lived with them for long, but I was not really sad to leave.
2. 用作从属连词，引导条件从句，as long as 带有假设意味，意思是“只须；假如；如果是；在...样的情形下”。
网友的第二句便是：
You can go out, as long as you promise to be back before eleven oclock.
只须你保证十一点前回来，你就能出去。
又如：
You can watch TV as long as you have finished your homework. 只须完成了作业，你就能看电视。
As long as you have passed the previous three relevant practice game, we can end the confrontation between rivals. 只须你通过了前面三关的训练赛，就能对决最后的对手。
As long as you come, I am happy. 你只须来我就开心。
Troubles fear me as long as I dont fear them. 我若不怕困难，困难就怕我。
as long as 引导的从句，还可以省略与主句相同的主语，然后用分词：
As long as going into the reading room，you should keep quiet. 只须进入阅览室，你就应维持安静。
