Passage Four
Increasingly, over the past ten years, people -- especially young people have become aware of the need to change their eating habits, because much of the food they eat, particularly processed food, is not good for the health.

Natural foods also include animals which have be
A. Vegetables and fruits with essential vitamins and minerals.
B. Foods grown in soil rich in organic matter.
C. Poultry fed in free pastures.
D. chickens raised on battery farms.

{{B}}Entertainment in London{{/B}} {{B}}Buying Books{{/B}} Londoners are great readers. They buy vast numbers of newspapers and magazines and even of books especially paperbacks, which are still comparatively cheap in spite of ever-increasing rises in the costs of printing. They still continue to buy "proper" books, too, printed on good paper and bound between hard covers. There are many streets in London containing shops which specialize in book-selling. Perhaps the best known of these is Charing Cross Road in the very heart of London. Here bookshops of all sorts and sizes are to be found, from the celebrated one which boasts of being "the biggest bookshop in the world" to the tiny, dusty little places which seem to have been left over from Dickens’ time. Some of these shops A. It’s to the cast of London. B. It’s street of bookstores. C. It’s a center for second-hand books. D. It’s where worthless books are sold. [简答题]为什么抗积炭性能是轻油蒸汽转化催化剂的主要性能？
