Rather than suggest a specific strategy, I'll tell you about a couple of things that have helped me with students like that.
--Is he involved in the book choices? For one of my guys, when he got involved, he had more "buy-in"on reading with expression.
--Do you have him do a strong "pre-tell" or picture walk? (Not sure how old he is).
--I often have these kinds of kiddos predict what words they might see in the book after our picture walk--writing them on a white board and checking off the ones we do read, and discussing what words were there in place of others on the list not found in the book.
Maybe these ideas will help :).
