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 relate to diet and forty percent of cancer relates 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 connected with illness is not 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.

　 A. Drug and Food             　B. Cancer and Health

My Opinion on Cheating in Examinations

It is known to us all that some students cheat in examinations at school.　　______________________________________________________________________________

Baekeland and Hartmann report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.

　　 In general, these “short sleeps” appeared ambitious, active, energetic, cheerful, conformist(不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full-or part-time while going to school. And many of them had a strong urge to appear “normal” or “acceptable” to their friends and associates.

　　When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.

　　The sleep patterns of the “short sleepers” were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic(疯人).

　　The “long sleepers” were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally robbed of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the “short sleepers.”

　　Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep was an escape from their daily problems.

According to the report,______.

　　A. many short sleepers need less sleep by nature

　　B. many short sleepers are forced to reduce their nightly sleep time because they are busy

        with their work

　　C. long sleepers sleep a longer period of time during the day

　　D. many long sleepers preserve their sleeping habit formed during their childhood

Many “short sleepers” are likely to hold the view that _____.

　　A. sleep is a withdrawal from the reality

　　B. sleep interferes with their sound judgment

　　C. sleep is the least expensive item on their routine program

　　D. sleep is the best way to deal with psychological troubles

It is stated in the third paragraph that short sleepers _____.

　　A. are ideally vigorous even under the pressures of life

　　B. often neglect the consequences of inadequate sleep

　　C. do not know how to relax properly

　　D. are more unlikely to run into mental problems

When sometimes they cannot enjoy adequate sleep, the long sleepers might ____.

　　A. appear disturbed                     B. become energetic

　　C. feel dissatisfied                        D. be extremely depressed
