求改一句英语句子
5% more people said they have exercise the month before the Healthy Living Survey than that in 1999
我就是想说2000 年做的Healthy living survey里面比1999 年做的 多了5%的人说他们在做survey之前那个月做过运动………… 求理顺语法

  5% more people said 以上是主句,之后是宾语从句 they have exercise(他们做运动) the month before the Healthy Living Survey(在Healthy Living Survey之前的一个月里)than that(这个that 指代做运动的peo...= = 这句话是我写的。。。 但我觉得不太顺总觉得有语法错误。。。你自己写的 怎么会理不出结构呢? 参考一下吧There are 5% more people who said that they did exercise the month before the Healthy Living Survey than that in 1990.
