单选题The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of cancer is related to the diet as well, especially cancer of the colon(结肠). Different cultures are more prone to contract certain illnesses because of the food that is characteristic in these cultures. That food related to illness is not a new discovery. In 1945, government researchers realized that nitrates(硝酸盐)and nitrites(亚硝酸盐), commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

单选题Galen, Andress Veaslius, and William Harvey were important figures in the history of man's study of his own body. Galen, a Greek who practiced medicine in Rome in the second century A. D., contributed immeasurably to the understanding of anatomy (解剖学). His dissections (解剖) were limited to Barbary apes, however, because Roman religious and philosophical attitudes made experimentation on the human body unthinkable. Even so, his reputation was so outstanding and his conclusions were so logical that his writings on anatomy and physiology were accepted by medical men for more than a thousand years. Vesalius, a Belgian who went to Paris to study medicine, made the first major successful challenge of the teachings and the theories of Galen. Vesalius shocked his professors by proposing that knowledge of human anatomy should be learned from human bodies. No one took him seriously because there was a French law prohibiting dissection of the human body. Vesalius, nevertheless, conducted research in secret. When he published his book on human anatomy in 1543, medical scientists criticized him for daring to attack the writings of Galen. Eighty - five years later, an English physician named Harvey published a book that disproved Galen's theory of blood circulation. Although Harvey's explanation was not universally accepted at the time, medical men of today credit him with one of the greatest advances in medical history.
