be worth doing 和be worth to be done 有什么区别?

2种形式从语法上讲都是正确的。
区别：前者是主动语态，例：He is worth trusting.；后者是被动语态，例：The exhibition is worth to be visited.

你弄错了，没有be worth to be done 这种形式，只有be worth doing sth 或者 be worthy to be done 现在知道了没？这两个意思是一样的，”值得做某事”

上面的那个满意回答是错的。形容词worth后面跟动名词的主动形式表示被动含义，但不能跟动词不定式；而worthy后面跟动词不定式的被动形式。
