问题描述：
分析句子成分 It's good for your health to do more sports.这句话中for your health做什么成分?
to do more sports 做主语； is 是系动词；it是形式主语； good是表语
那么for your health是做什么成分的?
句子还原后：To do more sports is good for your health.
我想知道的就是for your health具体是做什么成分的，做目的状语？还是就是跟good联在一块做表语？
答
It 做形式主语,那这句话可以变成To do more sports is good for your health,很明显,to do more sports 做主语,is 是系动词,根据主系表结构,那么good for your health作为一个整体,做表语.
