单选题Some desert animals can survive the summer heat and dryness because they are very unusual. The camel, for example, can experience and bear an increase in the temperature of its body and its blood of 9°C without anything bad happening to it. In addition, it can drink a lot of water at one time; then store enough water in parts of its body to supply its needs for two weeks or more. The kangaroo rat, on the other hand, gets all the water it needs from water that it produces when it breathes. However, most animals need to maintain a fairly constant body temperature, and will die if it rises more than 5°C. Therefore, they need to find some way to stay away from the heat of the summer sun. Nor can many animals either store or produce water in their bodies, as the camel and kangaroo rat can. So they must find ways to keep their bodies from losing water because of the heat. Because very few desert animals can survive the high temperature of a typical summer's day, most of them are active only in the night. Only after the sun has set does the desert come fully to life. The night is relatively cool. and the darkness provides protection, not only from the sun, but also from other animals and from the birds. So the coming of darkness is the signal for the large majority of animals and insects to start again their search for water and food. When morning comes, most of them seek shelter again: many go underground; nearly all find some dark and cool places where they, can keep away from the sun's heat. For many kinds of insects, living in the desert is easier than for animals. Like many desert plant's, they have a waterproof skin which prevents water loss because of the high temperature. In addition, some spend all or most of their life below ground. Here, for most of the year at least, it is moist, and it is generally cooler than on the surface. In the case of ants, only adults leave the underground nests, and they do so only to gather food or to defend the nest against attack.

单选题 Sport is not only physically challenging, but it can also be mentally challenging. Criticism from coaches, parents, and other teammates, as well as pressure to win can create an excessive amount of anxiety or stress for young athletes. Stress can be physical, emotional, or psychological, and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable. The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents' and coaches' criticisms to heart and find flaws (缺陷) in themselves. Coaches and parents should also be careful that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today' s youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game, many parents and coaches focus on the outcome and find fault with youngsters' performances. Positive reinforcement should be provided regardless of the outcome. Research indicates that positive reinforcement motivates and has a greater influence on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.

单选题Priscilla Ouchida's "energy-efficient" house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $ 100,000, three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned (双层玻璃的) windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Pricilla's eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness. Experts finally traced the cause of her illness. The level of formaldehyde (甲醛) gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting. The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation's drive to save energy. The problem itself isn't new. "The indoor environment was dirty long before energy conservation came along, "says Moschandreas, a pollution scientist at Geomet Technologies in Maryland. "Energy conservation has tended to accentuate the situation in some cases." The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn't worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom built up to dangerous levels.
