单选题Teaching involves more than leadership. Scene of the teacher's time and effort is directed toward instruction, some toward evaluation. But it is the teacher as a group leader who creates an efficient organizational structure and good working environment so that instruction and evaluation activities can take place. A group that is totally disorganized, unclear about its goals, or constantly fighting among its members will not be a good learning group. The leadership pattern includes helping to form and maintain a positive learning environment so that instruction and evaluation activities can take place. On the first day of class, the teacher faces a room filled with individuals. Perhaps a few closely united groups and friendships already exist. But there is no sense of group unity, no set of rules for conduct in the group, no feeling of belonging, if teachers are successful leaders, they will help students develop a system of relationships that encourages cooperation. Standards and rules must be established that maintain order, endure justice, and protect individual rights, but do not contradict school policy. What happens when one student hurts another's individual rights? Without clear guidelines mutually agreeable to students, teachers, and administration, the classroom can become chaotic. Students may break rules they did not know existed. If standards are set without input from the class, students may spend a great deal of creative energy in running the class environment, finding ways to break rules. No matter how skillful the teacher is in uniting students and establishing a positive atmosphere, the task is never complete. Regular maintenance is necessary. Conflicts arise, the needs of individual members change. A new kind of learning task requires a new organizational structure. Sometimes outside pressures such as holidays, upcoming tests or athletic contests, or family troubles cause stress in the classroom. One task for the teacher is to restore a positive environment by helping students cope with conflict, change, and stress.

单选题 Death comes quickly in the mountains. Winter holiday makers are caught unaware as they happily ski away from the fixed runs, little realizing that a small avalanche (雪崩) can send them crashing in a bone breaking fall down the slope and leave them buried under tons of white snow. There are lots of theories about how to avoid disaster when hit by an avalanche. Practice is normally less cheerful. The snow in the Salzburg of Austria where a recent disaster took place was typical avalanche material. For several days before the incident I had skied locally. Early winter snow was wearing thin and covered with ice. On top of that new, warmer flakes (雪片) were gently falling to produce a dangerous carpet. To the skier who enjoys unmarked slopes it is tempting stuff, deep new powder snow on a hard base—the skiing that dreams are made of. And sometimes nightmares. Snow falls in sections like a cake. Different sections will have different densities because of the temperatures at the time of the fall and in the weeks afterwards. Problems come when any particular section is too thick and not sticking to the section beneath. The snow of the past few weeks had been falling in rather higher temperatures than those of December and early January. The result of these conditions is that even a light increase in the temperature sends a thin stream of water between the new snow and the old. Then the new snow simply slides off the mountain. Such slides are not unexpected. Local citizens know the slopes which tend to avalanche and the weather in which such slides are like. Traps are Set to catch the snow or prevent it slipping; bombs are placed and exploded from time to time to set off small avalanches before a big one has time to build up; and, above all, skiers are warned not to ski in dangerous areas. In spite of this, avalanches happen in unexpected areas and, of course, skiers ignore, the warnings. The one comfort to recreational skiers, however, is that avalanche incidents on the,marked ski-slopes are quite rare. No ski area wants the image of being a death trap.

单选题Your''re off work and hanging out at home. 　　Off your diet and into cookies, big dinners and champagne. 　　Off your schedule, and up nights with movies, videos or a good book. 　　Off your workout routine and skipping your morning swim or evening run. 　　In short, you''re off, free of responsibilities and pressure, stuffed full of food and fun. And you don''t like it. 　　"All humans, and for that matter all species that are vertebrates and many that are not, have internal clock mechanism, "said George Brainard, professor of neurology at Thomas Jefferson University in Philadelphia." That''s not a metaphor. It''s an actual biological entity." 　　As many people find themselves in the second week of enforced indolence because of the winter break -- whether because of school holidays or time off from work -- more than a few may be experiencing a peculiar sensation. 　　A wave of discontent at the luxury of doing nothing, of sitting around with time to spare, the commodity of the late 20th century that we''re constantly told is in dangerously short supply. 　　The sense is that you should feel great, but actually you don''t. You hate to admit it, but it might even be a welcome break to go back to work or school. 　　"I enjoy being off, but I enjoy coming back too, "said Virgina Woodard of Chicago. 　　After several days off around Christmas, she was back at her baby-sitting job on New Year''s Eve, taking her 3-year-old charge to a museum. 　　"It messes up your schedule, and coming back is tiresome," said Woodard, who nonetheless said she enjoyed her time off. 　　"I feel like I''ll need a week to recover to get back on my schedule, "said Joni Lederer. She and her family shared the holidays at their Highland Park home with another family, and she has spent the days since taking her two sons skating ,bowling and to museums. 　　"Most people," said Brainard," do better and are healthier if they keep a regular social calendar to their life that is somewhat consistent with their internal timekeeping mechanism." 　　The changes in routine that commonly occur during the holidays come at a biological cost. Those changes disrupt the body clock, located primarily in the brain, and may produce an out-of-sorts feeling. 　　"Normal day-to-day routines and realities are very supportive of the internal clock structure that leads to good health," he added.
