请高手帮我分析下这个英语句子的结构
Yet the desirability of further economic growth for a society that is already wealthy has been questioned on grounds that undoubtedly have a good deal of vatility.意思是然而对于一个非常富足的社会而言是否有必要再一味追求发展,人们对此的质疑,无疑是有充分说服力的.
我想问后半句have的主语是谁,还是另有说法?前面句子结构明白,可是从on grounds that开始就不太明晰,第二个问题就是后半句的grounds后的that做什么成分,起什么作用?

解答

后面那个that 引导的是定语从句,修饰grounds,主语就是关系代词that,或者说是先行词grounds囧。。两个问题我也知道on ground that 是短语……囧两个问题都在我的回答里面问题一：have 的主语是谁——是grounds!问题二：grounds后的that做什么成分，起什么作用——that引导定语从句，在定语从句that undoubtedly have a good deal of vatility 中代替grounds做主语
