Question

as time goes by后面跟什么时态？

Answer 1

看例句：
As time goes by, spending on keeping people in old jobs will need to be cut, andreplaced with spending on training them for new ones. （一般将来时）
随着时间的推移，用在保留人员在旧工作岗位上的支出需要减掉，取而代之的是为新岗位培养劳动者的支出。
I love you more and more each day as time goes by. （一般现在时）
随着时间的流逝我每一天越来越爱你。

Answer 2

用过去时，相当于“时光飞逝，怎么怎么样……”
