be worth doing和be worth to be done的区别

没有be worth to be done的说法，只有be worth doing和be worthy to be done的说法。
worth是介系词，后面只能跟动名词的主动形式，但表示被动的意义，如：
The book is worth reading.
If something is worth doing, it's worth doing well.
worthy是形容词，这个词的后面要跟介系词of，of之后才要跟动名词的被动式，或者直接跟不定式的被动式。如：
The book is worthy of being read.
If something is worthy to be done, it's worth to be done well.
另外，还有一个字叫做worthwhile，也是形容词，它可以作表语，后面可以用动词不定式和动名词，作其真正的主语：
It's worthwhile to read the book.
If it's worthwhile doing something, it's worthwhile doing it well.

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.

be worth to be done
没此用法。
be worth后只接动名词不接不定式
be worthy后不接动名词，而接不定式(若该不定式要表示被动意义，则应用被动形式)。如：
　　He is worthy to receive such honor. 他应该得到这种荣誉。
　　This suggestion is worthy to be considered. 这个建议值得考虑。
若要在be worthy后接动名词，与后接名词时的情形一样，应借助介词of，且该动名词若要表示被动意义，要用被动形式。如：
　　He is worthy of filling [=to fill] the post. 这个职位他当之无愧。
　　This suggestion is worthy of being considered [=to be considered]. 这个建议值得考虑。
be worthwhile 后接动名词或不定式均可。如：
　　It is worthwhile buying the dictionary. 这本词典值得买。
　　It is worthwhile to discuss the plan again. 这个计划值得再讨论一次。
