In the following sentences, the subject of the main verb
is semantically the direct object of the -ing verb following
"worth" (or, in the case of , it's the object of the
preposition in the "worth" portion).
I'm investigating whether my fellow native speakers think
it's OK to add an overt possessive subject to the -ing
portion of such sentences. The (a) sentences below are
obviously correct. What about the (b) sentences? Thank you.
(1a) The Grand Canyon is worth seeing.
(1b) The Grand Canyon is worth your seeing.
(2a) These safety precautions are worth taking.
(2b) These safety precautions are worth our taking.
(3a) This is worth thinking about.
(3b) This is worth my thinking about.
(4a) That isn't worth doing.
(4b) That isn't worth John's doing, but it is worth Bob's.
All of the (b) sentences are unnatural, in my opinion.
