it's not as easy as it was when we were young 这是什么语法？as easy as it was 有什么作用？怎样用它？
it's not as easy as it was when we were young
意思是：这个（事情，行为）不再象我们年轻的时候（做这个事情）那么容易。
as easy as it was
意思是：如同这个（事情，行为）曾经是（那么的）容易
这里的：as ... as...结构用于比较句型,中间插入形容词或副词的原级。意思是"达到与什么相同的程度"。引导方式/比较状语从句。
其用法是说明当前的状态与想象中的（第二个as后引导的）状态程度不一样（有变化）。
