As for you,you'd better be quick.

这里的as指的是you'd better be quick（你最好快点）只有你最好快点才能与你对应，换句话说，你只有和“你最好快点”一样才能对应，显然，你现在慢，不能对应。

    As for the money; because I love you all,my fortune will be divided equally among you.

因为我爱你们大家，我的财产将平均分给你们。与钱对应。也就是这笔钱要与因为我爱你们大家，我的财产将平均分给你们有关。

又如：

As for Jerry, once he saw that his mother had gained her beach , he began the steep descent to the bay

   as指得是once he saw that his mother had gained her beach , he began the steep descent to the bay与Jerry关联:一旦他母亲去了海滩，他就去哪个海湾，这两件与Jerry关联，对应。
