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 all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon (结肠). Different cultures are prone (易于……的) to contract (染上疾病等) certain illnesses because of the food that is characteristic (特有的) in these cultures. That food is related to illness is not a new discovery. 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 given 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 It seems that food has ______ effects on person"s health.

A、 good
B、 bad
C、 great
D、 little

【正确答案】 C

【答案解析】[解析] 我们所吃的食物似乎对我们的健康有深远的影响。尽管科学上已取得许多进展，使食物更适合我们食用，但与此同时它也使许多食物不宜食用了。一些研究已经表明，人类大概有80%的疾病与饮食有关，40%的癌症，特别是结肠癌，也与饮食有关。不同的文化会使人们更易患某些疾病，这是由这些文化的人们喜好的食物所致。食物与疾病有关并不是新发现。农民常给牛和家禽注射青霉素，因此在受过注射的牛所产的牛奶里发现青霉素。有时让家禽服用这类药物并非是为了治病，而是为了经济上的缘故。农民们只是想使家畜长得更肥壮可以上市场上卖到更好的价钱。虽然食物和药品管理局已一再设法控制这种情况的发生，但是这种行为仍在继续。
