为什么As time went by,要用过去式？with time going by. wit

Question

为什么As time went by,要用过去式？with time going by. with要用进行时？这两个有啥区别？

Answer 1

要As time went by 是一个状语从句，它敍述过去的情况，所以要用过去时态，而with time going by 是一中独立结构，既即介词with+逻辑主语time+现在分词going by ，也做状语。

Answer 2

As time went by (随着时间的推移)是一个状语从句，time主语，went by 谓语。。敍述过去的情况用过去时态。
with time going by 是一个介词短语，time 是介词with的宾语，going by 是现在分词短语作宾语补足语，不是谓语，没有时态。
