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. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, 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 living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical 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.
Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasons
b.Some of the additives in our food are added to the food itself and some are given to the living animals

第12题：
问答题English food has a bad reputation abroad. This is most probably because foreigners in England are often obliged to eat in the more “popular” type of restaurant. Here it is necessary to prepare food rapidly in large quantities, and the taste of the food inevitably suffers, though its quality, from the point of view of nourishment, is quite satisfactory. Still, it is rather dull and not always attractively presented. Moreover, the Englishman eating in a cheap or medium price restaurant is usually in a hurry—at least at lunch—and a meal eaten in a leisurely manner in pleasant surroundings is always far more enjoyable than a meal taken hastily in a business-like atmosphere. In general, it is possible to get an adequate meal at a reasonable price; in fact, such a meal may be less expensive than similar food abroad. For those with money to spare, there are restaurants that compare favourably with the best in any country.正确答案：
英国食品在海外的名声不好。这很可能是因为去英国的外国人不得不常在更“大众化”的餐馆里用餐的缘故。在那里,必须大量迅速地备餐,因此饭菜的味道必然逊色,尽管在营养方面,饭菜质量还是令人满意的。可是饭菜仍然显得单调,颜色花样也常常不大讲究。此外,在价钱便宜或适中的饭店里用餐的英国人,通常是来去匆匆——至少午餐是如此——而在舒适的环境中从容就餐要比在生意氛围较浓的环境里匆匆忙忙地吃饭更有乐趣。一般来说,花不多的钱吃上一顿饱饭是可能的。事实上,同样的饭菜比国外或许还要便宜些。对于手头有富余的人来说,英国有一些饭店和国外最好的饭店相比还要划算。解析： 暂无解析 -
