沒有be worth to be done的說法，只有be worth doing和be worthy to be done的說法。

worth是介係詞，後面只能跟動名詞的主動形式，但表示被動的意義，如：

The book is worth reading.

If something is worth doing, it"s worth doing well.

worthy是形容詞，這個詞的後面要跟介係詞of，of之後才要跟動名詞的被動式，或者直接跟不定式的被動式。如：

The book is worthy of being read.

If something is worthy to be done, it"s worth to be done well.

另外，還有一個字叫做worthwhile，也是形容詞，它可以作表語，後面可以用動詞不定式和動名詞，作其真正的主語：

It"s worthwhile to read the book.

If it"s worthwhile doing something, it"s worthwhile doing it well.
