i ran faster than i had ever run before.这里的ever可以换成never吗?

问题描述:

i ran faster than i had ever run before.这里的ever可以换成never吗?
never用在否定句里所以不行吗?
这里的ever是什么意思?
我知道这句话的意思是:我从来没有跑得这么快过.
但是 i had ever run before 有点难懂.

i ran faster than i had ever run before.
一个词一个词翻译就是:我跑得比以前曾经跑得更快.
如果改为:i had never run before.
翻译就变成了:我以前从来都没有跑过.
与原句意思不对了..
