填空题 The Drink Your Body Needs Most1 Our bodies are estimated to be about 60% to 70% water. Blood is mostly water, and our muscles, lungs, and brain all contain a lot of water. Water is needed to regulate body temperature and to provide the means for nutrients (滋养物) to travel to all our organs. Water also transports oxygen to our cells, removes waste, and protects our joints and organs.2 We lose water through urination (排尿), respiration (呼吸), and by sweating. If you are very active, you lose more water than if you do not take much exercise. Symptoms of mild dehydration (脱水) include chronic pains in joints and muscles, lower back pain, headaches, and constipation (便秘). A strong smell to your urine, along with a yellow color indicates that you are not getting enough water. Thirst is an obvious sign of dehydration and in fact, you need water long before you feel thirsty.3 A good rule of thumb (好的做法) is to take your body weight in pounds and divide that number in half. That gives you the number of ounces (盎司) of water per day that you need. For example, if you weigh 160 pounds, you should drink at least 80 ounces of water per day. If you exercise you should drink another 8-ounce glass of water for every 20 minutes you are active. If you drink coffee or alcohol, you should add at least an equal amount of water. When you are traveling on an airplane, it is good to have 8 ounces of water for every hour you are on board the plane.4 It may be difficult to drink enough water on a busy day. Be sure you have water handy at all times by keeping a bottle for water with you when you are working, traveling, or exercising. If you get bored with plain water, add a bit of lemon for a touch of flavor. There are some brands of flavored water available, but some of them have sugar or artificial sweeteners that you don't need.

填空题Aromatherapy 1. Aromatherapy (芳香疗法) is a form of alternative medicine which is based on the use of very concentrated "essential" oils from the flowers, leaves, bark, branches or roots of plants which are considered to have healing properties. In aromatherapy these powerful oils are mixed with other oils, such as almond (杏仁) oil, or they are diluted (稀释) with water. These solutions (溶液剂) can be rubbed on the skin, sprayed in the air, or applied as a compress (敷药)。 2. Many people have aromatherapy massages (按摩), and depending on the treatment a person is having, the aromatherapist will massage the oil into the hands or shoulders. The massage is smooth and flowing, as it is designed to create a sense of relaxation and calm. The sessions are tailored to the individual"s health and mood at the time, so every session is unique. 3. Practioners of aromatherapy believe that the aroma of the "essential" oils directly stimulates the brain or that the oils are absorbed through the skin into the bloodstream, where they can affect the whole body and promote healing. Other claims in support of aromatherapy are that it aids digestion, improves the functioning of respiratory system, reduces muscular aches and pains, and promotes muscle relaxation and tone. It has also been argued that aromatherapy can improve circulation, lower blood pressure, and help combat insomnia (失眠) and other stress-related disorders such as tension headaches, anxiety, and mild depression. 4. However, while aromatherapy may have real effects that promote a sense of well-being, some traditional medicine practitioners remain doubtful about its powers. While research has confirmed that aromatherapy does have some positive short-term effects on most people, it also suggests that aromatherapy is not an actual science or medicine that should be used to treat illness. Furthermore, not all aromatherapy is considered beneficial to health. There are precautions which should be taken before having aromatherapy because some oils can have negative effects on people with certain medical conditions. The study of aromatherapy is relatively new and unexplored. More research needs to be conducted to make scientific conclusions about its use and effects. A．Current Research into Aromatherapy B．Aromatherapy and Conventional Medicine C．Different Views about Aromatherapy D．Introduction to Aromatherapy E．Doubts about the Benefits of Aromatherapy F．Personalized Aromatherapy Massage

This is a cliché(陈词滥调). In the land of black and white, people should not be too surprised to find some of the biggest gaps between the rich and the poor in the world. But the American Dream offers a way out to every-one. {{U}}(46) {{/U}} No class system or government stands in the way. Sadly, this old argument is no longer true. Over the past few decades there has been a fundamental shift in the structure of the American economy: The gap between the rich and the poor has widened and widened. {{U}}(47) {{/U}} Over the past 25 years the median US family income has gone up 18 percent. For the top 1 per cent, however, it has gone up 200 percent. Twenty-five years ago the top fifth of Americans had an average income 6.7 times that of the bottom fifth. {{U}}(48) {{/U}} Inequalities have grown worse in different regions. In California, incomes for lower class families have fallen by 4 percent since 1969. {{U}}(49) {{/U}} This has led to an economy hugely in favor of a small group of very rich Americans. The wealthiest 1 percent of households now control a third of the national wealth. There are now 37 million Americans living in poverty. At 12.7 percent of the population, it is the highest percentage in the developed world. Yet the tax burden on America's rich is falling, not growing. {{U}}(50) {{/U}} There was an economic theory holding that the rich spending more would benefit everyone as a whole. But clearly that theory has not worked in reality. A. Nobody is poor in the US. B. The top 0.01 percent of households has seen its tax bite fall by a full 25 percentage points since 1980. C. For upper class families they have risen 41 percent. D. Now it is 9.8 times. E. As it does so, the possibility to cross that gap gets smaller and smaller. F. All one has to do is to work hard and climb the ladder towards the top.

填空题China Seeks Donors to Narrow Bone Marrow Gap 1. China has launched a campaign to recruit more bone marrow donors, amid a shortage of funds as well as of sibling donors who could help the growing number of patients in need of life-saving transplants, state media reported on Monday. 2. The Chinese Red Cross began the national campaign over the weekend to find donors for some 4 million patients suffering from leukaemia, thalassaemia and other blood diseases and awaiting bone marrow transplants, the official China Daily said. Every year China has 40,000 new leukaemia patients, most of them under 35 and 50 percent of them children, the newspaper said. Other reports have linked China's growing childhood leukaemia to solvents and building materials used in interior decoration. 3. With a tiny pool of bone marrow donors, weakened by the absence of sibling donors for most children because of China's one-child policy, doctors rely on donors from Taiwan to save many young leukaemia patients, the Beijing Evening News said last weekend. Taiwan, with a population of 22 million, has 210,000 registered donors compared with fewer than 30,000 donors among mainland China's 1.3 billion people, the newspaper said. 4. Yet the lack of registered donors may reflect a lack of funding for testing and recording data on potential donors rather than a lack of volunteers, the newspaper said. China needs a pool of at least 100,000 donors but testing them would cost more than 50 million yuan, it said. 5. The Hong Kong Marrow Match Foundation said it has helped "a handful" of patients in Beijing, Shanghai and other cities. "The number of requests is increasing" from mainland China, including direct calls to the charity from desperate patients or relatives, said the foundation's donor coordinator Marven Chin. But the cost of extracting bone marrow from one of the foundation's 40,000 registered donors and flying it by courier has to be borne by the patients, and many of them have to be aided financially, Chin said.

填空题1. Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and, more recently, rubber and plastic. And that was where we stuck, in surgical instrument terms, for many years. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and industry, but which was also, in time, to revolutionize the art and science of surgery. 2. The tool is the laser and it is being used by more and more surgeons all over the world, for a very large number of different complaints. The word laser means: Light Amplification by Stimulated Emission of Radiation. As we all know, light is hot; any source of light--from the sun it self clown to a humble match burning--will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam. 3. Experiments with these pinpoint beams have shown researchers that different energy sources produce beams that have a particular effect on certain living cells. It is now possible for eye surgeons to operate on the back of the human eye without harming the front of the eye, simply by passing a laser beam right through the eyeball. No knives, no stitches, no unwanted damage--a true surgical wonder. 4. Operations which once left patients exhausted and in need of long periods of recovery time now leave them feeling relaxed and comfortable. So much more difficult operations can now be tried. 5. The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps some cancers will be treated with laser in a way that makes surgery not only safer but more effective. Altogether, tomorrow may see more and more information coming to light on the diseases which can be treated medically.

填空题 Leukemia Leukemia is the most common type of cancer kids get, but it is still very rare. Leukemia involves the blood and blood-forming organs, such as the bone marrow. {{U}} {{U}} 1 {{/U}} {{/U}} A kid with leukemia produces lots of abnormal white blood cells in the bone marrow. Usually, white blood cells fight infection, but the white blood cells in a person with leukemia don't work the way they're supposed to. {{U}} {{U}} 2 {{/U}} {{/U}}The abnormal white blood cells multiply out of control, filling the bone marrow and making it hard for enough normal, infection-fighting white blood cells to form. Other blood cells—such as red blood cells (that carry oxygen in the blood to the body's tissues) and platelets (that allow blood to clot)—are also crowded out by the white blood cells of leukemia. These cancer cells may also move to other parts of the body, including the bloodstream, where they continue to multiply and build up. Although leukemia can make kids sick, most of the time it is treatable, and kids get better. Almost all leukemia patients are treated with chemotherapy, which means using anti-cancer drugs. {{U}} {{U}} 3 {{/U}} {{/U}}Chemotherapy quickly goes to work, traveling through the blood to the bone marrow. There, the drugs can attack the cancer cells. After several weeks of chemotherapy, many kids begin to feel better. Some children with leukemia will also have to have radiation therapy, too. {{U}} {{U}} 4 {{/U}} {{/U}} If the cancer isn't getting better from using the usual amounts of chemotherapy and radiation, then a kid with leukemia will probably need more treatment—with higher doses of chemotherapy and radiation finally to kill the cancer cells. But this heavy-duty treatment will also harm the normal cells in the kid's bone marrow too, and the bone marrow will no longer be able to produce normal blood cells. So, doctors will then give a kid—or anyone else with bone marrow that is no longer working—normal bone marrow tissue from someone else who is healthy. {{U}} {{U}} 5 {{/U}} {{/U}} A．The chemotherapy drugs are given through a catheter, a narrow tube that is inserted into a blood vessel, sometimes in the kid's upper chest. B．Early symptoms of leukemia are often overlooked, since they may resemble symptoms of the flu or other common diseases. C．This is a special procedure called a bone marrow transplant, and it helps the patient make new blood cells so they can recover from the leukemia. D．Bone marrow is the innermost part of some bones where blood cells are first made. E．They don't protect the person from infections very well. F．Radiation therapy uses invisible high-energy waves (similar to X-rays) to kill cancerous cells.

填空题A．sell flesh vegetablesB．sell as much as possibleC．offer a variety of prepared mealsD．turn them into soupE．fill a gap in the marketF．promote her soups

填空题Transport and Trade 1 Transport is one of the aids to trade. By moving goods from places where they are plentiful to places where they are scarce, transport adds to their value. The more easily goods can be brought over the distance that separates producer and consumer, the better for trade. When there were no railways, no good roads, no canals, and only small sailing ships, trade was on a small scale. 2 The great advances made in transport during the last two hundred years were accompanied by a big increase in trade. Bigger and faster ships enabled a trade in meat to develop between Britain and New Zealand, for instance. Quicker transport makes possible mass-production and big business, drawing supplies from, and selling goods to, all parts of the globe. Big factories could not exist without transport to carry the large number of workers they need to and from their homes. Big city stores could not have developed unless customers could travel easily from the suburbs and goods delivered to their homes. Big cities could not survive unless food could be brought from a distance. 3 Transport also prevents waste. Much of the fish landed at the ports would be wasted if it could not be taken quickly to inland towns. Transport has given us a much greater variety of foods and goods since we no longer have to live on what is produced locally. Foods which at one time could be obtained only during a part of the year can now be obtained all through the year. Transport has raised the standard of living. 4 By moving fuel,raw materials,and even power,as ,for example,through electric cables, transport has led to the establishment of industries and trade in areas where they would have been impossible before. Districts and countries can concentrate on making things which they can do better and more cheaply than others and can then exchange them with one another. The cheaper and quicker transport becomes, the longer the distance over which goods can profitably be carried. Countries with poor transport have a lower standard of living. 5 Commerce requires not only the moving of goods and people but also the carrying of messages and information. Means of communication, like telephones, cables and radio, send information about prices, supplies, and changing conditions in different parts of the world. In this way, advanced communication systems also help to develop trade.A. Higher living standardB. Importance of transport in tradeC. Various means of transportD. Birth of transport-related industries and tradeE. Role of information in tradeF. Public transportation

填空题A. timely discovery of hurricaneB. convenienceC. sex equalityD. its connection with humansE. huge powerF. uncertainty

填空题Ginseng Shows Benefits in Cancer Treatment Flaxseed slowed the growth of prostate tumors in men, while ginseng helped relieve the fatigue that cancer patients often feel, U.S. researchers reported on Saturday in two of the first scientifically rigorous looks at alternative medicine. The studies reflect doctor"s 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 $46 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. 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. 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 cancer ceils in both the flaxseed groups grew about 30 to 40 percent slower than the control group. But Wendy 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 definitely 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. 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 1,000mg dose and twenty-seven percent of patients taking a 2,000mg dose said their fatigue symptoms were "moderately better" or "much better". Only 10 percent of those taking a 750mg 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 powered 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 in a large scale." The flaxseed study was funded by the National Institutes of Health and the ginseng study was supported by U.S. Public Health Service grants. A．The Motivation of Flaxseed Study B．The Study on Ginseng Displays Its Good Promise C．The Doctor"s Responsibilities Led them to Carry Out These Two Studies D．Ginseng Is as Good to Cancer Patients as Flaxseed E．The Methods and Results of the Study on Flaxseed F．A Different Opinion on the Use of Flaxseed

No matter what it is, whether it is films, food and fashion, music, casual sports or slang, it's soon at home elsewhere in the world. There are several theories why American popular culture has had this appeal. One theory is that it has been "advertised" and marketed through American films, popular music, and more recently, television. {{U}}(46) {{/U}} They are , after all, in competition with those produced by other countries. Another theory, probably a more common one, is that American popular culture is internationally associated with something called "the spirit of America. " {{U}}(47) {{/U}}. The final theory is less complex : American popular culture is popular because a lot of people in the world like it. Regardless of why it spreads, American popular culture is usually quite rapidly adopted and then adapted in many other countries. {{U}}(48) {{/U}} "Happy Birthday to You," for instance, is such an everyday song that its source, its American copyright, so to speak, is not remembered. Black leather jackets worn by many heroes in American movies could be found, a generation later, on all those young men who wanted to make this manly-look their own. Two areas where this continuing process is most clearly seen are clothing and music. Some people can still remember a time when T-shirts, jogging clothes, tennis shoes, denim jackets, and blue jeans were not common daily wear everywhere. Only twenty years ago, it was possible to spot an American in Paris by his or her clothes. No longer so: those bright colors, checkered jackets and trousers, hats and sock which were once made fun of in cartoons are back again in Paris as the latest fashion. {{U}}(49) {{/U}}. The situation with American popular music is more complex because in the beginning, when it was still clearly American, it was often strongly resisted. Jazz was once thought to be a great danger to youth and their morals, and was actually outlawed in several countries. Today, while still showing its rather American roots, it has become so well established. Rock & roll and all its variations, country & western music , all have more or less similar histories. They were first resisted. Often in America as well as being "low-class," and then as "a danger to our nation's youth. " {{U}}(50) {{/U}} And then the music became accepted and was extended and developed, and exported back to the US. A. As a result, its American origins and roots are often quickly forgotten. B. But this theory fails to explain why American films, music , and television programs are so popular in themselves. C. American in origin, informal clothing has become the world's first truly universal style. D. The BBC, for example, banned rock & roll until 1962. E. American food has become popular around the world, too. F. This spirit is variously described as being young and free, optimistic and confident, informal and disrespectful.

填空题How Much You Know About the Common Cold Many people catch a cold in the springtime or fall. It makes us wonder, if scientists can send a man to the moon, why can"t they find a cure for the common cold? The answer is easy. There are actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn"t a cure for each one. When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and cause a block in it. You feel terrible because you can"t breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells. You may feel miserable, but actually your wonderful body is doing everything it can to kill the cold virus. Different people have different cures for colds. In the United States and some other countries, for example, people might eat chicken soup to make themselves feel better. Some people take hot baths and drink warm liquids (流汁). Other people take medicine to stop various symptoms (症状) of colds. There is one interesting thing to note. Some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn"t have a way to fight it and kill it. Bodies can do an amazing job on their own. They can beat down the viruses by themselves. There is a joke, however, on taking medicine when you have a cold. It goes like this: It takes about one week to get over a cold if you don"t take medicine, but it takes only seven days to get over a cold if you take medicine.
