Some years ago, writing in my diary used to be a usual activity. I would return from school and spend the expected half hour recording the day’s events, feelings, and impressions in my little blue diary. I did not really need to express my emotions by way of words, but I gained a certain satisfaction from seeing my experiences forever recorded on paper. After all, isn’t accumulating memories a way of preserving the past?

　　When I was thirteen years old, I went on a long journey on foot in a great valley, well-equipped with pens, a diary, and a camera. During the trip, I was busy recording every incident, name and place I came across. I felt proud to be spending my time productively, dutifully preserving for future generations a detailed description of my travels. On my last night there, I wandered out of my tent, diary in hand. The sky was clear and lit by the glare of the moon, and the walls of the valley looked threatening behind their screen of shadows. I automatically took out my pen….

　　At that point, I understood that nothing I wrote could ever match or replace the few seconds I allowed myself to experience the dramatic beauty of the valley. All I remembered of the previous few days were the dull characterizations I had set down in my diary.

　　Now, I only write in my diary when I need to write down a special thought or feeling. I still love to record ideas and quotations that strike me in books, or observations that are particularly meaningful. I take pictures, but not very often—only of objects I find really beautiful. I’m no longer blindly satisfied with having something to remember when I grow old. I realize that life will simply pass me by if I stay behind the camera, busy preserving the present so as to live it in the future.

　　I don’t want to wake up one day and have nothing but a pile of pictures and notes. Maybe I won’t have as many exact representations of people and places; maybe I’ll forget certain facts, but at least the experiences will always remain inside me. I don’t live to make memories—I just live, and the memories form themselves.

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.

When did you last see a polar bear? On a trip to a zoo, perhaps? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3℃, and the water temperature was a bit higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group. This is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.

　　Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.

The Polar Bears themselves are satisfied with the benefits (or advantages) of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system（循环系统）because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.

　　The main benefits (or advantages) of cold-water swimming are probably mental. The Polar Bears love to swim year-round; they find it fun and relaxing. As one 70-year-old woman says. "When I go into the water, I pour my troubles into the ocean and let them float away."

In recent years, especially during the l960s, there was much discussion about “the brain drain (排干, 流失),” which dealt with the problem of students and learned people who left their own countries for other countries that offered better chances for study, research, and employment．For example, according to a report from U．N., between 1962 and l966 more than 50 percent of all engineering graduates of Iran and 14 percent of Iranian scientists left their country for work abroad．Over 30 percent of Chilean engineers and 15 percent of Turkish physicians also went to work in other countries．Probably the greatest brain drain occurred among young scientists who had gone abroad to study．Many of them had planned to return to their countries to teach but chose to remain in more industrialized nations where they were able to continue their work and their research in fields in which there were no job possibilities at home．The countries that attracted most of these scientists were the United States, Great Britain, Germany, France, Canada, and Australia.

　　Recent studies show that the brain drain to the United States may be decreasing．Many foreign scientists are going home again, and in some cases American scientists are leaving the United States for employment in other countries．The main reasons are that good jobs are becoming fewer here, money for national research has been sharply cut, and university fellowships reduced too．However, in the field of medicine the drain to the United States still goes on．Today more than one of every five American doctors is foreign - born, and several thousand foreign doctors immigrate to the United States each year．Over eighty countries have asked the State Department to send students who are skilled in important fields such as medicine back home when their study programs are over.

Which of the following is not the reason for “the brain drain”?

A．Good housing.　　           B．Better research condition.

C．Good job possibility　　      D．Better chances of study..

The brain drain to the United States may be decreasing mainly because __________.
