单选题{{B}}Text 3{{/B}} One of the best-known proverbs must be "early to bed, early to rise, makes a man healthy, wealthy, and wise." The promises of health, wealth, and wisdom to those who join the ranks of the early retires and risers must be particularly appealing to many people in our contemporary society. There is no doubt that one of the greatest concerns of modern man is his health. It is estimated that in the United States $ 200 billion are spent on health care each year. The medical field has grown into such a big business that it employs 4.8 million people, and it appears that in many places, more staff is needed to meet the demands of the people who are concerned about their physical well-being. Much more interest has been shown in preventive medicine in recent years. This is probably due in part to the increasing costs of medical treatment, but the writings of such people as Dr. Keneth Cooper have also played an important role. In his book Aerobics. Dr. Cooper communicated his message of the benefits of exercise so effectively that many other authors have flowed in his trail, and literally millions of readers have put on their sports shoes and taken to the highways and byways of America. A recent survey showed that over 17 million people are jogging. Many of these are so serious that they have trained themselves to run the 26 miles and 385 yards of the hard and tiring marathons that are sponsored all over the country. The last time I was in Honolulu, I was amazed to see hundreds of people, young and old, running for their lives, and I discovered many of them have run in the Hawaiian Marathon. Exercise has also become a major part of conversation. A1 a dinner party recently, the president of a bank asked me, "You look like a runner; how far do you run each day?" A few days later when I appeared on a national television show, the host suddenly asked me if I was a regular runner. On both occasions the conversation turned to the subject of exercise and I found, as I have found whenever I have traveled recently, that this is a subject on many people's minds. Of course, there are still many people who are less than enthusiastic about exercise. They appreciate the philosophy of Robert M. Hutchins who said, "Whenever the thought of exercise occurs to me, I lie down till it passes."

单选题{{B}}Text 2{{/B}} Centuries ago, man discovered that removing moisture from food helps to preserve it, and that the easiest way to do this is to expose the food to sun and wind. All foods contain water--cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80% , lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌) which cause food to go bad is checked. Nowadays most foods are dried mechanically. The conventional method of such dehydration(脱水) is to put food in chambers through which hoi air is blown at temperatures of about 110°C at entry to about 43°C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish. Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Dried foods 'take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.
