They are no longer places for the privileged few or for bored vacationers to visit on rainy days. Action and democracy are words used in descriptions of museums now.2. At a science museum in Ontario, Canada, you can feel your hair stand on end as harmless electricity passes through your body. At the Metropolitan Museum of Art in New York City, you can look at 17th century instruments while listening to their music. At the Modem Museum in Sweden, you can put on costumes provided by the Stockholm Opera. As these examples show, museums are reaching out to new audiences, particularly the young, the poor, and the less educated members 'of the population. As a result, attendance is increasing.3. More and more, museums directors are realizing that people learn best when they can somehow become part of what they are seeing. In many science museums, for example, there are no guided tours. The visitor is encouraged to touch, listen, operate, and experiment so as to discover scientific principles for himself. He can have the experience of operating a spaceship or a computer. He can experiment with glass blowing and paper making. The purpose is not only to provide fun but also to help people feel at home in the world (y[ science. The theory is that people who do not understand science will probably fear it, and those who fear science will not use it to best advantage. Many museums now provide educational services and children's departments. In addition to the usual displays, they also offer film showings and dance programs. Instead of being places that one "should" visit, they are places to enjoy.4. One cause of all these changes is the increase in wealth and leisure time. Another cause is the rising percentage of young people in the population. Many of these young people are college students or college graduates. They are better educated than their parents. They see things in a new and different way. They are not content to stand and look at works of art; they want art they can participate in. The same is true of science and history. In the US, certain groups who formerly were too poor to care about anything beyond the basic needs of daily life are now becoming curious about the world around them. The young people in these groups ,like young people in general, have benefited from a better education than their parents received. All these groups, and the rest of the population as well, have been influenced by television, which has taught them about other places and other times.5. The effect of all this has been to change existing museums and to encourage the building of new ones. In the US and Canada alone, there are now more than 6,000 museums, almost twice as many as there were 25 years ago. About half of them are devoted to history, and the rest are evenly divided between the arts and sciences. The number of visitors, according to the American Association of museums, has risen to more than 700 million a year.6. In fact, the crowds of visitors at some museums are creating a major problem. Admission to museums has always been either free or very inexpensive, but now some museums are charging entrance fees for the first time or raising their prices. Even when raised, however, entrance fees are generally too low to support a museum, with its usually large building and its highly trained staff.

填空题 Bedwetting (尿床) Millions of kids and teenagers from every part of the world wet the bed every single night. It's so common that there are probably other kids in your class who do it. Most kids don't tell their friends, so it's easy to feel kind of alone, like you might be the only one on the whole planet who wets the bed. {{U}} {{U}} 1 {{/U}} {{/U}} The fancy name for bedwetting is nocturnal enuresis. Enuresis runs in families. This means that if you urinate, or pee, while you are asleep, there's a good chance that a close relative also did it when he or she was a kid. {{U}} {{U}} 2 {{/U}} {{/U}} The most important thing to remember is that no one wets the bed on purpose. It doesn't mean that you're lazy or a slob. {{U}} {{U}} 3 {{/U}} {{/U}}For some reason, kids who wet the bed are not able to feel that their bladders is full and don't wake up to pee in the toilet. Sometimes a kid who wets the bed will have a realistic dream that he's in the bathroom peeing—only to wake up later and discover he's all wet. Many kids who wet the bed are very deep sleepers. {{U}} {{U}} 4 {{/U}} {{/U}} Some kids who wet the bed do it every single night. Others wet some nights and are dry on others. A lot of kids say that they seem to be drier when they sleep at a friend's or a relative's house. {{U}} {{U}} 5 {{/U}} {{/U}}So the brain may be thinking, "Hey, you! Don't wet someone else's bed!" This can help you stay dry if you're not aware of it. A. The good news is that almost all kids who wet the bed eventually stop. B. Trying to wake up someone who wets the bed is often like trying to wake a log—they just stay asleep. C. It's something you can't help doing. D. Just like you may have inherited your mom's blue eyes or your uncles' long legs, you probably inherited bedwetting, too. E. That's because kids who are anxious about wetting the bed may not sleep much or only very lightly. F. But you are not alone.

Every 3.1 minutes, someone dies of one. Stroke killed an estimated 167,661 people in 2000 and is the nation's third leading cause of death, ranking behind diseases of the heart and all forms of cancer. Stroke is a leading cause a serious, long-term disability in the United States. 2 Stroke is a type of cardiovascular(心血管的)disease. It affects the arteries (动脉)leading to and within the brain. A stroke occurs when a blood vessel that carries oxygen and nutrients(营养物) to the brain is either blocked by a clot(凝块)or bursts. When that happens, part of the brain cannot get the blood (and oxygen) it needs, so it starts to die. 3 The brain is an extremely complex organ that controls various body functions. If a stroke occurs and blood flow can't reach the region that controls a particular body function, that part of the body won't work as it should. If the stroke occurs toward the back of the brain, for instance, it's likely that some disability involving vision will result. The effects of a stroke depend primarily on the location of the obstruction(阻塞) and the extent of brain tissue affected. 4 The American Stroke Association has identified several factors that increase the risk of stroke. The more risk factors a person has, the greater the chance that he or she will have a stroke. Some of these you can't control, such as increasing age, family health history, race, and prior stroke. But you can change or treat other risk factors to lower your risk. Factors resulting from life-style or environment can be modified with a healthcare provider's help. Some of these include: high blood pressure, current smoking, heart disease, and high red blood cell count. 5 A stroke can happen to anyone at any moment. In fact about 600,000 people have strokes every year. For many years, there was no hope for those suffering a stroke. However, recent breakthroughs have led to new treatments. For the treatments to work, the person must get to a hospital immediately. A. Effects of a stroke B. Annual cost of stroke in the US C. Definition and description of a stroke D. Breakthroughs in treatment E. Risk factors of stroke F. Warning signs of a stroke

填空题 Caring for the Old The old do not have to look exclusively to the past. Relieved of some of life's responsibilities and fortified by many years of experience and knowledge, they may have a much better idea of how to spend their time enjoyably than they did in their youth. And not all enjoyment is restricted to the mental or philosophical. Healthy physical activity remains quite possible for most of us well into our later years. Old people sometimes display surprising freedom and forthrightness in the expression of their thoughts and feelings, and an ability to transmit affection. It is as though some of the rituals which constrict us in earlier life fall away. But a higher percentage of people suffer from emotional distress in old age than at any other time in adult life, and the gap between need and care is often filled by dubious measures, such as heavy-handed prescription of medicine. For many years it was assumed that old people were not appropriate candidates for psychotherapy. But a few clinicians have risen to the challenge and discovered that individual and group psychotherapy is just as effective with the old as with the young. It is easy to understand why an earthquake causes terror. Yet in old age there may be terror of a very private nature, a sense of disintegration sometimes stemming from inner conflicts, sometimes from a premonition of death or the fear of becoming dependent. Dependency is a grim choice: insecurity and deprivation must be weighed against loss of autonomy and integrity. But if there is nothing shameful about the dependency of a baby or a young child, there should be nothing shameful about the dependencies natural with old age and diminishing physical resources. The complexity and impersonality of the bureaucratic establishments, which have the means to provide help, are often threatening to old people. The younger generation today, on the other hand, will have had many decades to interact with "the system" by the time they reach old age. Many of us, including healthcare providers, assume that we know what old people and dying people want, but our assumptions are often a reflections of our won thoughts and feelings based on personal interpretations of scanty bits of observation. Such assumptions are really an excuse to avoid close contact with the terminally ill. Assuming we "know" what they want, we observe ourselves from being with them, and sharing their thoughts about the end of life. We sometimes assume, wrongly, that old people are too confused or senile to be aware of the nearness of death. In consequence, communication between a dying and others is subject to extraordinary omissions and distortions. "Protecting" the dying from knowledge of their condition often serves to protect us from the uncomfortable prospect of talking about dying and death. Evasions like this only lead to increasing isolation at a time when emotional honesty and understanding are most needed.

Health and Human Services Secretary Tommy Thompson signed the Framework Convention on Tobacco Control (FCTC) this week at the United Nations. The Senate must still approve the treaty before the US can implement its provisions. 2 The FCTC was developed by the World Health Organization and approved by members of the World Health Assembly, including the United States, last year. Countries that ratify it would be required to enact strict tobacco control policies. 3 For instance, cigarettes sold in those countries would have to have health warnings on at least 30% of the front and back of every pack. The treaty calls for higher tobacco taxes, restrictions on smoking in public places, and more promotion of tobacco prevention and cessation programs. It also requires bans on tobacco advertising, though there are some exceptions for countries like the United States, where the Constitution prohibits such an outright ban. 4 The impact of the treaty could be huge. The World Health Organization estimates that tobacco use kills nearly 5 million people worldwide every year. In the US alone, about 440,000 people die each year from tobacco-related illnesses; about one-third of all cancers in the US are caused by tobacco use. If current trends continue, WHO estimates, by 2025 tobacco will kill 10 million people each year. 5 The treaty must be ratified by at least 40 countries before it can take effect. So far, 109 countries have signed it, and 12 have ratified it.

填空题Science and Technology There is a difference between science and technology. 1 Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for applying the findings of science. 2 Progress in science excludes the human factor. Scientists, who seek to understand the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other peoples likes or dislikes or to popular ideas about the fitness of things. 3 But even an unpleasant truth is more than likely to be useful; besides, we have the choice of refusing to believe it! But hardly so with technology; we do not have the choice of refusing to hear the sound produced by a supersonic (超音速的) aircraft flying overhead; we cannot refuse to breathe polluted air. 4 The purpose of technology is to serve people—people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves. 5 Many people blame technology itself for widespread pollution, resource depletion (枯竭) and even social decay in general—so much so that the promise of technology is "obscured". That promise is a cleaner and healthier world. If wise applications of science and technology do not lead to a better world, what else will? A. Another distinction between science and technology has to do with the progress in each. B. Unlike science, progress in technology must be measured in terms of the human factor. C. What scientists discover may shock or anger people—as did Darwin"s theory of evolution. D. Science and technology are different. E. We are all familiar with the improper use of technology. F. Science is a method of answering theoretical questions; technology is a method of solving practical problems.

填空题 A Doctor in the House Brushing your teeth twice a day should keep the dentist away. But if a group of scientific researchers have their wish, it will make the rest of your body healthy too. {{U}} {{U}} 1 {{/U}} {{/U}}It is one of many gadgets (小装置) proposed by engineers and doctors at the Center for Future Health in New York—others include a pair of glasses that help to jog your memory, and a home camera designed to check for cancer. The devices seem fanciful, but the basic principles are simple. The gadgets should make it easy for people to detect illness long before it strikes and so seek treatment far earlier than normal. {{U}} {{U}} 2 {{/U}} {{/U}}In the long run, the technology may even prevent illness by encouraging us to lead healthier lives. Intelligent bandages (绷带) are a good example. Powerful sensors within the bandage could quickly identify tiny amounts of bacteria in a wound and determine which antibiotics (抗生素) would work best. {{U}} {{U}} 3 {{/U}} {{/U}} Socks are long overdue for a makeover. In the future they will be able to automatically detect the amount of pressure in your foot and alert you when an ulcer (溃疡) is coming up. All the projects should have far-reaching implications, but the biggest single development is a melanoma (黑瘤) monitor designed to give early warnings of cancer. {{U}} {{U}} 4 {{/U}} {{/U}}. If a problem is found, the system would advise you to get a check-up at your doctor's surgery. If all this sounds troublesome, then help is at hand. {{U}} {{U}} 5 {{/U}} {{/U}}. A standard computer would be able to understand your voice and answer questions about your symptoms in plain English and in a way which would calm your nerves. A. The device could be used to take a picture of your body each week, then compare it with previous images. B. That is going to be the difficult part. C. The cut could then be treated instantly so avoiding possible complications. D. Experts are also working on a "digital doctor", completing it with a comforting bedside manner. E. Instead of relying on hi-tech hospitals, the emphasis is shifted to the home and easy-to-use gadgets. F. A toothbrush that checks blood sugar and bacteria while you brush is currently in development in USA.

填空题Old Man Myths and Realities 1 When does a middle-aged man become an old man? Officially, of course, it"s when we reach retirement age. But, as we all know, this is a fairly blunt (生硬的) method of decision making. As life expectancy(预期寿命) increases, retirement planning needs to be changed. This is because being an old man today is very different from what it was a generation or so ago. 2 Sixty-five is the new middle-aged man. These days people are talking about the young-old, that is ages 70-75, and those over 75 as the old-old. The young-old frequently continue in good health and maintain strong links with friends and family. The old-old have a much higher chance of poor health and social isolation. 3 Although men are living longer, there are still more old women than old men. This fact alone should arouse interest as to why. Relatively little is actually known about why this is the case or about the experiences of the old man. Sure, we are aware that the old man experiences anxiety, financial problems, loneliness, etc. , but that"s really about all we know. 4 It is usually believed that the old man often complains about their health. In fact, most rate their health as good even though most are diagnosed with at least one chronic illness. The physical health of the old man is strongly affected by their health behavior when they were younger.

填空题Exercising Year Memory 1 Aging does not mean a dramatic decline in memory power, unless you help it happen by letting your mind go. 2 That"s not to say that memory, doesn"t change throughout life. Researchers divide memory into categories based on the length of time when memories are stored. One system divides it up as short-term ( less than one minute ; remembering a telephone number while you dial, for instance) , long-term ( over a period of years) and very long-term memory (over a lifetime). 3 Short-term memory isn"t mastered until about age 7, but after that you never lose it. Long-term memory, however, involves more effort and skill and changes more through life. It"s not until the early teens(十几岁 ) that most people develop a mature long-term memory. 4 First, we must get information into our heads through learning. Learning strategies can get rusty (生绣) without constant use. High school and college students, who are forced to repeatedly exercise their long- term memory abilities ( at least long-term enough to get them through a final exam), usually do well on memory tests. The longer you stay in school, the more chance you get to polish your learning skills. It"s no wonder that more highly educated people have more effective memory skills throughout life. 5 Although older people in general learn somewhat more slowly than they did when younger, a dramatic difference exists between those who stay intellectually active—reading, discussing, taking classes, thinking—and those who do not. Giving the brain daily workout (锻炼) is just as important as exercising your muscles. Brainwork keeps your learning strategies in shape, and this helps your memory to function at full capacity. 6 The next part of a healthy, long-term memory is retention (记忆力), the ability to store what you have learned. Memory researchers still do not know whether memories are lost—whether they still exist in the brain but our mental searching cannot turn them up, or have disappeared entirely as our brain ages. 7 The third necessity for memory is recall, the ability to bring to mind the memories we have stored. Again, while aging has widely different effects on the recall abilities of different people, research indicates that the older we get, the longer it takes to recall facts. But slower recall is still recall. In fact, aging does not seem to have any effect on forgetting at all, which takes place at the same rate in younger and older people.

填空题 The Story of Lani Five-year-old Lani still takes seven medicines with her breakfast every morning. "She's very good about it," says her father David. Lani is alive today because of her father David, in more than one way; when she was one year old she received part of her father's liver in a liver transplant operation. Lani was born with a liver illness. {{U}} {{U}} 1 {{/U}} {{/U}}Doctors advised that a transplant was the only way in which she would live. The operation lasted 12 hours and needed two teams, one for the father and one for the daughter. {{U}} {{U}} 2 {{/U}} {{/U}}In these cases, the donor's liver grows to normal size in about eight weeks. And the child's liver becomes smaller. Lani spent three weeks in hospital after the operation. Because the receiver's body tries to reject the new organ, the patient has to be given special drugs. {{U}} {{U}} 3 {{/U}} {{/U}} Although David left hospital after 10 days, he didn't return to work until after three months. In order to reach the liver, the doctors have to cut through the stomach wall, which is strong and full of muscle. It therefore takes a long time to recover after this operation. {{U}} {{U}} 4 {{/U}} {{/U}}So far, only 16 of these liver-transplant operations have been carried out in Britain. {{U}} {{U}} 5 {{/U}} {{/U}}Doctors say, "If possible, we prefer to take a liver from a dead donor, usually a parent." Lani still has to look after her health, and she gets more tired than other children of the same age, but doctors hope that she will continue to get stronger and stronger. A．She had one operation when she was six weeks old, which was not successful. B．While these drugs are given, it is important that the patient does not catch any illness, not even a cold. C．In this operation a piece of liver, weighing about 250—300 grams, was removed from the father and transplanted into the daughter. D．David quickly recovered from the operation. E．However, they are more common in North America and Japan. F．David was finally able to ride his bike again after about a year.

The newly designed office was made with environmentally safe building materials instead of building products that are harmful to the environment. For example, the floor of the office is made of bark(树皮)from a cork tree. The bark of a cork tree will renew itself so the tree does not die. The cork floor also feels good to stand on. 3. The floor in another part of the office is made of bamboo(竹子). Bamboo is a fast-growing grass that quickly replaces itself. Other areas of the floor are covered with carpeting. However, unlike many offices, the carpet was made without harmful chemicals. 4. Storage areas in the office are made from the crushed shells of sunflower seeds. The office doors are made from pressed wheat straw. Wheat straw is an agriculture waste product that would normally be burned. That process adds chemicals to the atmosphere. 5. World Resources Institute officials also chose lighting and other electrical equipment that use less energy. And, they improved their communication systems. New video communication equipment lets workers see and talk to people in other cities. The new equipment was added to reduce the amount of travel by office workers. That reduces the amount of harmful gases that are released into the atmosphere by cars or planes. 6. The organization's officials also announced a plan that would reduce harmful carbon dioxide gases from their office by the year 2005. 7. World Resources Institute officials say the cost of building a "green" office is similar to that of a traditional office. They say building more "green" offices could lead to a healthier environment. They say a healthy environment and a strong economy can exist together. The organization says it is creating a work environment that is better for people.
