听力原文： What can hospitals do to help patients recover faster from illness？ Apart from nursing and medicine, (26)one way that is getting more attention is to improve the quality of the environment in hospitals. (27) Now some of Britain's most talented artists have been called in to transform. older hospitals. Of the 2 500 National Health Service hospitals in Britain, (27)almost 100 now have large collections of contemporary art in corridors, waiting areas and treatment rooms.
(28)These recent creative ideas owe a great deal to one artist, Peter Senior. He set up his studio at a Manchester hospital in northeastern England during the early 1970s. (29)He felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience.
A typical hospital waiting room might have as many as 5 000 visitors each week. What better place to hold regular exhibitions of art! Senior was so popular that he was soon joined by six young art school graduates.
The effect was striking. Now in the corridors and waiting moms the visitors have a full view of fresh colors, amusing images and peaceful courtyards.
The quality of the environment may reduce the expensive drugs when a patient is recovering from an illness. According to a study, patients who had a view of a garden needed half the number of strong pain killers compared with patients who had only a brick wall to look at. Those lucky patients said they used to be so upset when they saw the dull environment in hospitals.
