填空题 Electromagnetic Energy 1. White light seems to be a combination of all colors. The energy that comes from a source of light is not limited to the kind of energy you can see. Heat is given off by a flame or an electric light. On a cloudy day it is possible to get a sunburn even though you feel cool. Visible light and the kinds of energy that produce warmth and sunburn are examples of electromagnetic energy. 2. The sun is 93 million miles from the earth. Yet we can use energy from the sun because electromagnetic energy travels through space. 3. Many other kinds of energy are also types of electromagnetic energy. Radio, television, and radar signals travel from transmitters to receivers as low-energy electromagnetic waves. Infrared (红外线的) radiation is an electromagnetic wave. When it is absorbed by matter, heat is produced. Waves of infrared and visible light have more energy than waves of radio, television, or radar. Ultraviolet rays (紫外线) and X-rays are electromagnetic waves with even greater amounts of energy. Infrared radiation is used in cooking food and heating buildings. Sunlight and electric lights are part of our requirements for normal living. Ultraviolet radiation is useful in killing certain disease organisms. X-rays and gamma rays have so much energy that they travel right through solid objects. They can be used to detect and treat cancer. X-rays are used in industry to find hidden cracks in metal, and in medicine to reveal broken bones. 4. Usually we use electricity to generate electromagnetic energy. The source of most of our energy is the sun. Heat from the sun causes water to evaporate. When the water falls to the earth as rain, some of it is trapped behind dams and then used to operate electric generators. Other generators are powered by coal, but the energy stored in coal came from the sun, too. 5. Until recently, the source of the tremendous amount of energy given off by the sun was a puzzle. If the sun depended on chemical reactions, it would have used up all its energy long ago. Experiments with electromagnetic radiation led to the theory that mass can be converted into energy. About forty years after the theory was proposed, nuclear energy was harnessed (利用) by man. Chemical energy comes from electron (电子) rearrangement. Nuclear energy comes from a change in the nucleus of an atom. Compared with chemical reactions, nuclear reactions release millions of times more energy per pound of fuel. We now believe that the sun's energy comes from the nuclear reactions in which hydrogen is changed into helium (氦). 6. Nuclear energy is beginning to compete with coal as an economical source of power to generate electricity. It is also being used to operate engines in large ships. Scientists continue to seek new and better methods of obtaining and using energy. A．Nuclear Reactions as the Lasting Source of the Sun's Energy B．The Most Important Source of Energy C．Types of Electromagnetic Energy D．X-rays Are Used to Detect and Treat Cancer E．Seeking New Sources of Energy F．Nuclear Energy Is Beginning to Compete with Coal

填空题Ward off Travel Bugs 1. As the holiday season approaches, so does the prospect of jet lag, an upset stomach or sunburn. With care and some help from natural sources, however, it is quite possible to avoid these problems. 2. You can start to prepare a couple of weeks before you leave. Food poisoning will make any holiday miserable, but by taking some medicine such as lactobacillus and bifidobacteria, you can reduce the likelihood of succumbing to poisoning brought on by food or water tainted with unfamiliar bacteria. 3. By improving the bacteria balance in your digestive tract, you crowd out the pathogenic bacteria and stop them gaining a foothold. The beneficial bacteria also produce gentle but effective natural antibiotics in your gut. 4. In many holiday locations you need to remember the basics: drink bottled water, avoid undercooked meat and ensure that food hygiene is adequate. If you do succumb to food poisoning, drink plenty of water to stay hydrated and see a doctor. However, if you detect diarrhea early enough, you might like to try taking about 10 or 15 pancreatic digestive enzymes, which can digest the multiplying bacteria before they take over. 5. Taking a teaspoon of silicol gel can also help. This lines the stomach and upper intestinal area and binds with bacteria and viruses, allowing them to be safely passed out of the gut. When you pack, include grapefruit-seed extract, which is an excellent all-round anti-bacterial. antiparasitic, anti-viral and anti-fungal agent. 6. Your flight can also be made more pleasant. Peppermint oil and ginger capsules ward off motion sickness, but a more delicious option is to nibble on crystallized ginger. If you tend to get earache on take-off and landing, you can use special earplugs with filler that slows down the rate of change in air pressure. 7. The greatest concern is "economy class syndrome", the popular name for deep-vein thrombosis, which can lead to blood clots traveling from the legs to the lungs, heart or brain. To reduce this, you need a couple of hours to stay hydrated, and avoid alcohol. 8. You can also reduce the severity of inflammation by taking a daily gram of vitamin C with the bioflavonoid quercetin. Vitamin C and quercetin also help to reduce prickly heat. 9. Finally, if any adverse symptoms persist while overseas, you should see a doctor.

填空题Air Pollution 1 In 2002, the Earth Summit was held in Johannesburg in South Africa. One of the main themes of the summit was "sustainable development", or the question how we can continue developing the world without damaging the environment. 2 In Johannesburg, experts from all over the world spoke about different topics and discussed new ways to solve old problems. Most of the speakers talked about the "big three", the three biggest killers in the world-contaminated drinking water, poor sanitation and air pollution. According to the World Health Organization, the big three cause more than seven million deaths every year. That is 15% of all the deaths in the world. 20% of the people on earth do not have access to clean drinking water. Air pollution alone causes almost three million deaths. Most of these deaths happen in rural areas, where people burn wood and coal to cook food and stay warm. Air pollution is especially a big problem in very large cities, especially in developing countries. 3 Air pollution can spread from city to city. It even spreads from one country to another. Some northern European countries have had "black snow" from pollutants that have traveled through the air from other countries and have fallen with the snow. So air pollution is really a global problem. 4 Air pollution can kill babies, older people, and those who have diseases with their breath. As found in cities, air pollution increases the risks of certain lung diseases. 5 Air pollution can cause both airplane and car accidents because it cuts down visibility. There are other possible health dangers from air pollution that we don't know much about. For example, scientists are trying to find out whether chemicals that reach us from the air may cause changes in our cells. These changes might cause babies to be born with serious birth defects. Scientists are trying to learn how all the many chemicals we are apt to take into our bodies work. That is another reason why it is so important to begin to control pollution now instead of waiting until we learn all the answers. 6 Air pollution costs us a lot of money. It corrodes our buildings. It damages from crops and forests. It has a destructive effect on our works of art. The cost of all this damage to our government is great. It would be much more worthwhile, both for us and for the government, to spend our tax dollars on air pollution control.A. Cost moneyB. The big three killersC. We should spend money to control itD. The effect of air pollution to peopleE. Air pollution is a global problemF. The effect of air pollution to works

填空题 阅读下面这篇短文，短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第2～5段每段选择1个正确的小标题；(2)第27～30题要求从所给的6个选项中选择4个正确选项，分别完成每个句子。 {{B}} Lung Cancer{{/B}} 1 The death rate due to cancer of the lungs has increased more than 800 percent in males and has more than doubled in females during the last 25 years. It is considerably higher in urban and industrial areas than in rural districts. There are many possible causes, but it is still controversial which are most blameworthy. Those factors which have been mentioned most frequently are the presence of foreign particles and other irritants in the air (smoke particles, smog, exhaust fumes), and the smoking of cigarettes and cigars. 2 Numerous studies have demonstrated a striking correlation between the death rate from lung cancer and smoking habits. Among heavy smokers -- 21 to 30 cigarettes per day -- the mortality rate from lung cancer is nearly 17 times the rate from nonsmokers. It is expected the death rate among women will increase as the present high rate of smoking among women has its effect. 3 Sometimes cases of lung cancer are discovered at the time an x-ray is taken for the purpose of detecting tuberculosis. Too often, however, a current emphasis upon the danger of exposure to radiation from X-ray machines can frighten people away from routine chest X-rays and thus prevent an early diagnosis of lung cancer. Early detection is absolutely essential if any possibility of cure is to be maintained. Modern X-ray machines in competent hands pose such slight danger, at least to those over 40 years of age, that this would be much more than offset by the advantages of discovering a tumor while it is small enough to be completely removed. 4 A common form of lung cancer is bronchogenic carcinoma4, so-called because the malignancy originates in a bronchus. The tumor may grow until the bronchus is blocked, cutting off the supply of air to that lung. The lung then collapses, and the secretions trapped in the lung spaces become infected, with a resulting pneumonia or the formation of a lung abscess. Such a lung cancer can also spread to cause secondary growths in the lymph nodes of the chest and neck as well as in the brain and other parts of the body. The only treatment that offers a possibility of cure, before secondary growths have had time to form, is to remove the lung completely. This operation is called pneumonectomy. 5 Malignant tumors of the stomach, the breast, the prostate gland and other organs may spread to the lungs, causing secondary growths.

填空题The Invader of AIDS His invader is small, even in the microscopic world of bacteria and viruses. It is alive only in the strictest sense of the world. It had no intelligence, no means of mobility, and no methods of defense in the outside world. It is fragile, easily killed by common household bleach (漂白剂) and even short periods outside the body. 1 It is the AIDS virus, and it is a killer. AIDS is a disease, caused by a virus that breaks down part of the body"s immune system, leaving a person defenseless against a variety of unusual life-threatening illnesses. 2 . The body"s immune system normally provides us the weapons we need to win constant battles with invading viruses, bacteria and other invading organisms. His defense system is powerful but not perfect. 3 . We do not even know that anything is happening. But the AIDS virus acts differently from other invaders. It attacks the very cells that normally protect us. 4 . It turns our own white blood cells into mini-factories or making more viruses. Each time a cell is taken over, it fills up with thousands of new viruses, dies and releases those viruses, with attack more white blood cells. After enough attacks, our defense system is weakened and certain infections and conditions that we normally fight off with no problem take advantage of his weakness. 5 . The person dies. There is no cure for AIDS, so learning about the disease and how to avoid it are our only weapons. A. Yet it may be the most dangerous enemy in human history B. Whatever condition develops because of AIDS, the outcome is always the same C. It gets inside these cells into mini-factors D. Each of the letters in AIDS stands for a word: Acquired Immune Deficiency Syndrome E. The patients who suffer from AIDS have characteristic features F. Most attacks are detected and beaten off with ease

填空题How did English Become a Global Language? 1 The rise of English is a remarkable tale as Professor David Crystal reminds us in his attractive, short book "English as a Global Language. " 2 It is certainly quite a theme. When Julius Caesar landed in Britain more than 2,000 years ago,English did not exist. Five hundred years later, English, virtually incomprehensible to modern ears,was probably spoken by about as few people as currently speak Cherokee, the language of a small North American Indian tribe and with as little influence. About 1,000 years later, at the end of the 16th century,and after the Norman Conquest, the Reformation and the arrival of commercial printing technology,English was the native speech of between 5 million and 7 million people. And yet now look at it. As the second millennium approaches, English is more widely scattered, more widely spoken and written than any other language has ever been. In the title of the book it has become a truly global language. According to David Crystal,about 2.09 billion people,well over one-third of the world's population are routinely exposed to it. 3 As he rightly points out,what is impressive about this staggering figure is "not so much the grand total but the speed with which expansion has taken place since the 1950's. In 1950, the case for English as a world language would have been no more than plausible. Fifty years on and the case is virtually won. " 4 So what happened? 5 Someone once said that a language is a dialect with an army and a navy. In other words, when the British navy set out to conquer the world,it set out an "army" of English speakers. As the British empire spread throughout the world, English became the basis of law commerce and education. The British empire was succeeded by another (the American) ,which shared virtually the same linguistic heritage. American English, which has become the rocket-fuel of the English language, has magically found its way into areas undreamed of 40, let alone 400 years ago. 6 The most valuable part of Crystal's study is the section devoted to a speedy analysis of the cultural basis of this global reach, notably the influence of broadcasting, press, advertising, popular music and film. He is also up-to-date and informative in his identification of the WorldWide-Web as a powerful reinforcer of American cultural and linguistic dominance. 7 One of his most interesting passages concerns the role played by the League of Nations,and later the United Nations, in spreading English as an international language in the aftermath of the two world wars. 8 What does the future hold? To this question, Crystal proposes the recognition of a new form of English-WSSE(World Standard Spoken English)-which almost by definition rules out the possibility that English would fragment into mutually unintelligible languages as Latin once did . "English,in some shape or form,will find itself in the service of the world community forever, "Crystal writes.A. The future of EnglishB. The speed of the spread of EnglishC. The role played by culture and the netD. The role played by military expansionE. The role played by educationF. The 2,000 years of English

填空题Ginseng Shows Benefit in Cancer Treatment 1. Flaxseed slowed the growth of prostate tumors in men, while ginseng helped relieve the fatigue that cancer patients often feel, US researchers reported on Saturday in two of the first scientifically rigorous looks at alternative medicine. 2. The studies reflect doctors' efforts to explore the risks and benefits of foods and supplements that are routinely taken by their patients with little scientific proof they help. Americans spend between $36 billion and $47 billion a year on complementary and alternative therapies, according to the National Center for Health Statistics. "Patients are taking these compounds but we need to know if they are doing any good or any harm, " said Dr. Bruce Cheson of Georgetown University Hospital in Washington, who led a panel on alternative therapies at a meeting of the American Society of Clinical Oncology. 3. In the flaxseed study, researchers at Duke University Medical Center in North Carolina and colleagues evaluated the seed's role as a food supplement in 161 men who were scheduled to undergo surgery for prostate cancer. "The growth rate was decreased in the men who got flaxseed, " said Dr. Nancy Davidson, an oncologist at Johns Hopkins University in Baltimore who is president-elect of ASCO. "I think this is fascinating. " Flaxseed is rich in omega-3 fatty acids and lignins, a fiber found on the seed coat. "We were looking at flaxseed because of its unique nutrient profile, " said Wendy Demark-Wahnefried, a researcher in Duke's School of Nursing, who led the study. 4. Half of the men in the study added 30 grams of flaxseed daily to their diets for about 30 days. Half of the flaxseed group also went on a low-fat diet. After the surgery, the researchers looked at the men's tumor cells to see how quickly the cancer had multiplied. The cancer cells in both the flaxseed groups grew about 30 to 40 percent slower than the control group. 5. But Demark-Wahnefried is not ready to prescribe flaxseed. "It's a healthy food. It has a lot of vitamins and a lot of fiber. But we can not definitively say at this point you should take flaxseed because it is protective against prostate cancer, " she said, adding that flaxseed now needed to be studied to see if it can prevent prostate cancer. 6. In the ginseng trial, Debra Barton of the Mayo Clinic in Rochester, Minnesota, and colleagues tested three different doses of the herb on patients with a variety of cancers who were expected to live at least six months. Twenty-five percent of patients taking a 1,000-mg dose and twenty-seven percent of patients taking a 2,OOO-mg dose said their fatigue symptoms were "moderately better" or "much better. " Only 10 percent of those taking a 750-mg dose reported an improvement, which was about the same as the placebo group. Patients in the trial took Wisconsin ginseng from a single crop that was tested for uniform potency. It was powdered and given in a capsule form. "I wouldn't have predicted this, I have to admit, " Davidson said in an interview. "We might want to test this on a large scale. " 7. The flaxseed study was funded by the National Institutes of Health and the ginseng study was supported by US Public Health Service grants.

填空题Breaking the News about Your Diagnosis 1. When I was diagnosed with breast cancer nearly a year ago, I found myself at a loss for words at first. Over time, however, I developed some pointers (点子), which I hope will help others. 2. During the first few weeks of emotional "aftershocks" (余悸) from the diagnosis, I found myself unable to utter the word "cancer". Still, I wanted to share the news with my relatives and friends who already knew that I"d had a biopsy (活组织检查) and were anxiously awaiting my telephone call. I did the best I could, which is all anyone can do in this situation. When I called them, I said, "What we feared has happened." They immediately knew what I meant. 3. Nearly a year after my diagnosis, I find myself more comfortable telling people "I was diagnosed with cancer" instead of saying "I have cancer." On some deep level, I don"t want to "own" this illness. Choose language that suits you when you share your news. And keep in mind that there is no one "right" way of doing this. 4. Most people, after hearing your announcement, will be curious about the next step. They may wonder if you will be undergoing radiation therapy (诊疗) and/or chemotherapy (化疗). They may wonder where and when you will have surgery. Answer their questions as best you can, but keep in mind that "I don"t know right now" or "I"m still in too much shock to think about that" are good answers. 5. Wait until the initial wave of strong emotions has passed before telling the children in your life. Don"t overwhelm (使不知所措) very young children with too much information. Assure them that, even if you will be in the hospital for a while, they will see you every day and they will be cared for. Older children may already fear the word "cancer", so be prepared to reassure them. Emphasize the positive steps that doctors will be taking to treat your illness.

填空题How We Form First Impression We all have first impression of someone we just met. But why? Why do we form an opinion about someone without really knowing anything about him or her—aside perhaps from a few remarks or readily observable traits? The answer is related to how your brain allows you to be aware of the world. Your brain is so sensitive in picking up facial traits, even very minor difference in how a person"s eyes, ears, nose, or mouth are placed in relation to each other make you see him or her as different. In fact, your brain continuously processes incoming sensory information—the sights and sounds of your world. These incoming "signals" are compared against a host of "memories" stored in the brain areas called the cortex (大脑皮层) system to determine what these new signals "mean". If you see someone you know and like at school, your brain says "familiar and safe". If you see someone new, it says, "new—potentially threatening". Then your brain starts to match features of this stranger with other "known" memories. The height, weight, dress, ethnicity, gestures and tone of voice are all matched up. The more unfamiliar the characteristics, the more your brain may say, "This is new. I don"t like this person." Or else, "I am intrigued." Or your brain may perceive a new face but familiar clothes, ethnicity, gestures—like your other friends; so your brain says. "I like this person." But these preliminary "impressions" can be dead wrong. When we stereotype people, we use a less mature form of thinking, like the immature thinking of a very young child that makes simplistic and categorical impressions of others. Rather than learn about the depth and breadth of people—their history, interest, values, strengths, and true character—we categorize them as jocks, geeks, or freaks. However, if we resist initial stereotypical impressions, we have a chance to be aware of what a person is truly like. If we spend time with a person, hear about his or her life, hopes, dreams, and become aware of the person"s character, we use a different, more mature style of thinking—and the most complex areas of our cortex.

A pain shot from her knee and drove Lobo to the floor. Tests revealed that Lobo had tom her anterior cruciate (十字的,交叉的) ligament (韧带), or ACL, resulting in the end of her play for the season.{{U}} (2) {{/U}}. Lobo, perhaps the most recognized player in the United States, is one of a growing number of female athletes suffering ACL injuries. Experts say that female athletes in middle school, high school, college and professional sports may be eight times as likely as male athletes to experience ACL injury. {{U}} (3) {{/U}}. Why are so many female athletes falling victim to ACL injuries? Sports physicians say one reason is the growing number of females involved in high-impact sports, such as soccer and basketball. Jeff Bauer, a biochemist, however, thinks bone size plays a key role. He examined the knee joints of skeletons of 200 humans who had died at an early age. Studies of the skeletons of 100 males and 100 females showed in measurement after measurement that the bones making up a female's knee are smaller than those of a male of the same size. Smaller bone surfaces may lead to an increase in stress placed on the ACL during sharp movements, such as turning, jumping, or stopping. Bauer thinks the size difference may be the primary reason that females injure their knees more often than males do with the same amount of training and experience. "Now, that's not bad, "adds Bauer, "and it's not good. It's just different." Following the knee injury, Lobo underwent surgery.{{U}} (4) {{/U}}.

填空题 More Than 8 Hours Sleep Too Much of a Good Thing 1. Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 2. Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night's sleep than 8-hour sleepers. 3. These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night's rest may not need to set aside more than 8 hours a night. He added that "it might be a good idea" for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4. Previous studies have shown the potential dangers of chronic shortages of sleep—for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5. For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep, and having fatigue interfere with clay-to-day functioning. 6. Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bed. "It stands to reason that if a person spends too long a time in bed, then they'll spend a higher percentage of time awake," he said.
