ln the centuries___,Egypt became one of the most advanced civilizations on earth.为什么用following为什么用which followed 而不是FOLLOWED

In the (时期/期间） which followed, 是用作解释某件事情之后，继续的期间里所发生的事情。基本上就是 "After that" 的用法一样。中文里相等的词句应该是[在接下来的日子里]
Her mother died in December. In the months which followed, she cried every night.她母亲12月去世了。在接下来的数个月里，她每晚都会痛哭。
The earthquake happened on Saturday. In the days which followed, various organisations send food and aid to the victims.地震在星期六发生。在接下来的数天，许多组织都送出了食物和救济品。
本文译
在接下来的数个世纪，埃及成为了地球上最先进的文明。
顺带一提，following其实也可以用，语法不同但意思一样。
Her mother died in December. In the following months，she cried every night.
The earthquake happened on Saturday. In the following days, various organisations send food and aid to the victims.
ln the following centuries,Egypt became one of the most advanced civilizations on earth.

用 following
怎么可能 应该是followed吧 希望楼主仔细看看
