Passage OneAnimals have different ways of protecting themselves against wintertime weather. Some animals grow heavy coats of fur or feathers, while others dig into the ground to find a warm wintertime home.Some animals spend the winter in a deep sleep because by going to sleep they avoid the time of the year when food is scarce and the temperatures are low. Their sleep is known as hibernation.There is much about hibernation that puzzles scientists. For example, they are wondering how hibernation came into being. Some scientists have explored the possibility that animals release a chemical that starts them hibernating.One thing that scientists are certain about is that animals hibernate only when it is cold. Hibernation is a seasonal practice.Some animals that fall into a wintertime sleep are not true hibernators because they spend only a part of the cold season asleep. Bears, for example, can easily be awakened from their winter nap. They are not true hibernators.Sometimes it is difficult to determine whether a particular animal is a true hibernator. For example, some mice hibernate, but others do not. The same is true of bats. Some of them hibernate. Others do not.36. Hibernation is a seasonal practice. This means it ______.A. takes place only during a particular seasonB. occurs only during the nightC. is a daily practiceD. only happens when a species becomes over-populated

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.What are nitrates used for? a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.

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.
