单选题We all know that the normal human daily cycle of activity is of some 748 hours' sleep alternating with some 16,417 hours' wakefulness and that, broadly speaking, the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified. The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakeful-ness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts are changed every week: a person may work from 12 midnight to 8 a. m. one week, 8 a. m. to 4 p. m. the next, and 4 p. m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to an- other, so that much of his time is spent neither working nor sleeping very efficiently. The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night shift workers was carried out by Brown in 1957. She found a high incidence of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work. This latter system then appears to be the best long-term policy, but meanwhile some- thing may be done to relieve the strains of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People engaged in normal day- time work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only adjust gradually back to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance. Therefore, by taking body temperature at intervals of two hours throughout the period of wakefulness it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for Selection. So far, however, such a form of selection does not seem to have been applied in practice.

单选题Pulling heavy suitcases all day in the summer is hard work, especially when you're a thin 14-year- old. That was me in 1940—the youngest and smallest baggage boy at New York City's Pennsylvania Railway Station. After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I'd like to join them, thinking, "Everyone else is doing it." When I got home that night, I told my dad what I wanted to do. "You give an honest day's work," he said, looking at me straight in the eye. "They're paying you. If they want to do that, you let them do that." I followed my dad's advice for the rest of that summer and have lived by his words ever since. Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me. Now I teach my players to have respect for other people and their possessions. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he'd be gone. Whether you're on a sports team, in an office or a member of a family, if you can't trust one another, there's going to be trouble.

单选题 In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: they eat too much. But scientific evidence does little to support this idea. Going back to the America of the 1910s, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less and didn't watch television. Several modern studies, moreover, have shown that fatter people do not eat more on the average than thinner people. In fact, some investigations, such as the 1979 study of 3 545 London office workers, report that, on balance, fat people eat less than slimmer people. Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts: The more the men ran, the more body fat they lost. The more they ran, the greater amount of food they ate. Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
