求雅思剑6上的一句翻译
剑6的Test1中Passage1的最后一题
题目是这个By how much did some cyclists’ performance improve at the 1996 Olympic Games?
答案应该是这一句At the Atlanta Olympic Games in 1996, these sliced as much as two per cent off cyclists and rowers times.
请问这个two per cent 是2%还是20%?为什么答案是20 percent呢?是我理解错误还是怎么着?

two per cent 是2%
sliced as much as two per cent off cyclists and rowers times.slice在这应该是减去的意思,也就是说去掉2%,应该与前边的 一个数值相比较少了2%.
你再仔细看看前面是不是有22%的数据
