The polyester bottle was born in the 1970s, when soft drinks companies like Coca Cola started selling their drinks in giant two-liter containers. Because of the build-up of the pressure of gas in these large containers, glass was unsuitable. Nor was PVC, the plastic which had been used for bottles since the 1960s, suitable for drinks with gas in them. A new plastic had to be made.

　　Glass is still cheaper for the smaller bottles, and will continue to be so unless oil and plastic become much cheaper, but plastic does well for the larger sizes.

　　Polyester bottles are virtually unbreakable. The manufacturers claim they are also lighter, less noisy when being handled, and can be reused. Shopkeepers and other business people are unlikely to object to a change from glass to polyester, since these bottles mean few breakages, which are costly and time-consuming. The public, though, have been more difficult to persuade. ICI's commercial department is developing different bottles with interesting shapes, to try and make them visually more attractive to the public.

　　The next step could be to develop a plastic which could replace tins for food. The problem here is the high temperatures necessary for cooking the food in the container.

　　Directions： The passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, D. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.

　　The medical world is gradually realizing that the quality of the environment in hospitals may play a significant role in the process of recovery from illness.

　　As part of a nationwide effort in Britain to bring art out of the galleries and into public places, some of the country's most talented artists have been called in to transform older hospitals and to soften the hard edges of modern buildings. Of the 2,500 National Health Service hospitals in Britain, almost 100 now have significant collections of contemporary art in corridors, waiting areas and treatment rooms.

　　These recent initiatives owe a great deal to one artist, Peter Senior, who set up his studio at a Manchester hospital in northeastern England during the early 1970s. 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 500 visitors each week. What better place to hold regular exhibitions of art? Senior held the first exhibition of his own paintings in the out-patients waiting area of the Manchester Royal Hospital in 1975. Believed to be Britain's first hospital artist, Senior was so much in demand that he was soon joined by a team of six young art school graduates.

　　The effect is striking. Now in the corridors and waiting rooms the visitor experiences a full view of fresh colors, playful images and restful courtyards.

　　The quality of the environment may reduce the need for expensive drugs when a patient is recovering from an illness. A study has shown that patients who had a view onto a garden needed half the number of strong pain killers compared with patients who had no view at all or only a brick wall to look at.

　　21. According to the passage, "to soften the hard edges of modern buildings" means

　　A. to pull down hospital buildings

　　B. to decorate hospitals with art collections

　　C. to improve the quality of treatment in hospitals

　　D. to make the corners of hospital buildings round

　　A. He is a pioneer in introducing art into hospitals.

　　B. He is a doctor interested in painting.

　　C. He is an artist who has a large collection of paintings.

　　D. He is a faithful follower of hospital art.

　　23. According to Peter Senior, _______.

　　A. art is losing its audience in modern society

　　B. art galleries should be changed into hospitals
