example: The book is worth being read carefully.
Isn't my example worth adding to this list, however?It's a very rare construction. In the British National Corpus, a large database of real English from a variety of sources, there are only three examples of 'worth being' with a past participle:
(1) I am only worth being used. [written by a character in a novel]
(2) Help them to stick up for themselves and see that it is not worth being treated badly just in order to have a best friend.
(3) he declares it is worth being lost [after a shipwreck] when reunion is so pleasant
And we probably shouldn't count (3), as 'lost' is more like an adjective. To me (1) sounds odd, though (2) is natural. Basically, this construction might be possible in rare circumstances, but it's not something you ever need to use.
