In this point, reading for pleasure, both paper­based and on­screen, is far more helpful than watching TV. For example, there is always a book which is opened with expectation and closed with profit:  imagination.

B　[词义猜测题。根据本段第一句“The books that help you most in imagination are those that make you think most.”可知，培养想象力的书可以帮助你更多地思考，因此不看书会使人思考力下降。因此该词在句中意为“下降，减少”。故选B。]
