单选题During the 19th century scientists found that when certain parts of the brain were (36) , men lost the (37) to do certain things. And so people thought that each part of the brain does a (38) job. But modern research has found out that this is (39) , for it is not easy to say exactly what each part of the head does. In the past fifty years there (40) a great increase in the amount of research (41) on the brain. Chemists and biologists have (42) that the way the brain works is not so simple (43) people had thought. Chemists tell us that about 100,000 chemical changes (44) in the brain every second.

单选题My father's reaction to the bank building at 43rd Street and Fifth Avenue in New York city was immediate and definite: "You won't catch me putting my money in there!" he declared, "Not in that glass box!" Of course, my father is a gentleman of the old school, a member of the generation to whom a good deal of modern architecture is upsetting, but I am convinced that his negative response was not so much to the architecture as to a violation of his concept of the nature of money. In his generation money was thought of as a real commodity (实物) that could be carried, or stolen. Consequently, to attract the custom of a sensible man, a bank had to have heavy wails, barred windows, and bronze doors, to affirm the fact, however untrue, that money would be safe inside. If a building's design made it appear impenetrable, the institution was necessarily reliable, and the meaning of the heavy wall as an architecture symbol dwelt in the prevailing attitude toward money. But the attitude toward money has, of course, changed. Excepting pocket money, cash of any kind is now rarely used; money as a tangible commodity has largely been replaced by credit. A deficit(赤字) economy, accompanied by huge expansion, has led us to think of money as product of the creative imagination. The banker no longer offers us a safe: he offers us a service in which the most valuable element is the creativity for the invention of large numbers. It is in no way surprising, in view of this change in attitude, that we are witnessing the disappearance of the heavy-walled bank. Just as the older bank emphasized its strength, this bank by its architecture boasts of imaginative powers. From this point of view it is hard to say where architecture ends and human assertion (主张) begins.

单选题LONDON (Reuters)—Organic fruit, delivered right to the doorstep. That is what Gabriel Gold prefers, and he is willing to pay for it. If this is not possible, the 26-year-old computer technician will spend the extra money at the supermarket to buy organic food. "Organic produce is always better," Gold said. "The food is free of pesticides (农药), and you are generally supporting family farms instead of large farms. And at most times it is locally (本 地) grown and seasonal, so it is more tasty." Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business. But how many shoppers really know what they are getting, and why they are willing to pay a higher price for organic produce? Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences — but their knowledge of organic food is far from complete. For example, small amounts of pesticides can be used on organic products. And about three quarters of organic food in Britain is not local but imported (进口) to meet growing demand. "The demand for organic food is increasing by about one third every year, so it is a very fast-growing market," said Sue Flock, a specialist in this line of business.
