单选题Ideas about education are changing in the United States. Education today is not just a high school diploma or a college degree. Many adults are not interested in going to college. They are interested in other kinds of learning. For them, learning does not end with a diploma. Continuing education gives these adults the opportunity to increase their knowledge about their own field or to learn about a new field. It also gives them a chance to improve their old skills or to learn new ones, Secretaries, mechanics, and barbers can take classes to improve their work skills. Nurses can take classes to increase their knowledge of nursing. If they know more or learn more, then they can get a better job or earn more money. Continuing education classes give some adults the chance to learn new skills. There is usually a large variety of classes to choose from, typing, foreign cooking, photography, auto repair, furniture repair, or swimming. These are only some of the classes available. Some adults take classes for fun or because the class will be useful for them. For example, they can choose a class in almost any language, Chinese, Spanish or English as a second language. There are classes in first aid or classes in sewing. There are also many other type of classes to choose from. Other adults take continuing education classes to improve their own lives because they want to feel better about themselves. Overweight people can find exercise classes. Others can learn how to be good parents, or how to get along with other people. There are many opportunities for adults to continue their learning. Almost any community college or public school system has a continuing education program. There are classes in schools, community buildings, or churches. Most classes are in the evening, so working people can attend. The classes are usually small, and they are inexpensive. Thousands of people register for continuing education classes each year. They receive no diploma or certificate, and no grade for most of the classes they attend. For them, learning is something they do because they want to.

单选题{{B}}Text 2{{/B}} Within 30 years, humans could be debating whether to take charge of their own evolution. The average life span in the developed world will be 90, diseases will be diagnosed before symptoms appear, many humans will already be genetically modified and patients with heart diseases, cancer or dangerous infections will be treated with prescriptions tailored to their own genetic makeup, according to Francis Collins, one of the leaders of the project to sequence the entire human genome. By 2010, Collins told in a major international biotechnology forum in France this week, there could be predictive tests for at least 12 hereditary conditions, and scientists would understand the role that genes played in most common diseases. Embryoes developed by in vitro fertilization methods would be routinely scanned for genetic illnesses. Legislation to prevent genetic discrimination—the creation of an underclass denied health care, employment or insurance because of this genetic knowledge—could be in place within 10 years. By 2020, the designer drugs based on research on the human genome will be coming on to the market. The pharmaceutical industry would have produced powerful treatments for diabetes, hypertension, heart disease and schizophrenia. By 2030, if all went well, there should be comprehensive health care based on genetic knowledge, with individual medicine based on individual risk. Doctors would understand better the links between genes and environmental factors. Illnesses would be detected much earlier by molecular surveillance, even before symptoms appeared, and therapies would be more effective and more available. Collins also foresaw that by 2030, people would be arguing, as British physicist Stephen Hawking already is, that humans could start to take charge of their own evolution by altering their genes to improve the species.

单选题Text　　Most young people enjoy some form of physical activity. It may be walking, cycling or swimming, in winter, or skating or skiing. It may be a game of some kind — football, hockey, golf or tennis. It may be mountaineering.　　These who have a passion (26) climbing high and difficult mountains are often (27) with astonishment. Why are men and women (28) to suffer cold and hardship, and to (29) on high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activity (30) which men give their leisure.　　Mountaineering is a sport and not a game. There are no man-made roles, as there are for (31) games as golf and football. There are, of course, rules of different kinds which it would be dangerous to (32) ,but it is this freedom from man-made rules (33) makes mountaineering attractive to many people. Those who climb mountains are free to use their own (34) .　　If we (35) mountaineering with other more familiar sports, we might think that one big difference is (36) mountaineering is not a" team work". We should be mistaken in this. There are, it is true, no "matches" (37) "teams" of climbers, but when climbers are on a rock face linked by a rope on which their lives may (38) ,there is obviously teamwork.　　A mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight (39) of nature. His sport requires high mental and (40) qualities.　　A mountain climber (41) to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions (42) in their early twenties. But it is not (43) for men of fifty or sixty to climb the highest mountains in the Alps. They may take more (44) than younger men, but they probably climb with more skill and less (45) of effort, and they certainly experience equal enjoyment.
