Today the crater is still very much alive in the workshop that Graham Smith has set up. He is one of the few people in the country who make hand-cut weathervanes. Graham's designs are individually created and tailored to the specific requirements of his customers. "That way I can produce a unique per signalized item", he explains. A lot of my customers are women buying presents for their husbands. They want a distinctive gift that represents the man's business or leisure interests." It's all a far cry from the traditional cock, the most common design for weathervanes. It's was not a cock but a witch on a broomstick that featured on the first weathervane Graham ever made. Frieds admired his surprise present for his wife and began asking him to make vanes for them. "I realized that when it came to subjects that could be made into them, the possibilities were limitless," he says. {{U}}(46) {{/U}}. He had served an apprenticeship as a precision engineer and had worked in that trade for 15 years when he and his wife, Liz, agreed to swap roles—she went out to work as an architectural assistant and he stayed at home to look after the children and build up the business. That was five years ago and he has no regrets about his new direction. "My previous work didn't have an artistic element to it, whereas this is exciting and creative," he says. "I really enjoy the design side."{{U}} (47) {{/U}}. He works to very fling detail, aways seeking approval for the design of the silhouette from the customer before proceeding with the hand-cutting. Graham also keeps plenty of traditional designs in stock, since they prove as popular as the one-offs. "It seems that people are attracted to handcrafting," Graham says. "They welcome the opportunity to acquire something a little bit different" {{U}}(48) {{/U}}. "I have found my place in the market. People love the individuality and I get a lot of saris faction from seeing a nondescript shape turn into something almost lifelike," he says {{U}}(49) {{/U}}. "And nowadays, with more and more people moving to the country, individuals want to put an exclusive finishing touch to their properties. It has been a boost to crafts tike mines {{U}}(50) {{/U}}." American and Danish buyers in particular are showing interest. "Pricing," he explains, "depends on the intricacy of the design. "His most recent request was for a curly-coated dog. Whatever the occasion, Graham can create a gift with a difference.[A] Graham has become increasingly busy, supplying flat-weathervanes to clients worldwide.[B] Graham decided to concentrate his efforts on a weathervane business.[C] Last month, a local school was opened with his galleon ship weathervane hoisted above it.[D] "For centuries, weathervanes have kept communities in touch with the elements, signaling those shifts in wind direction that bring about changes in the weather," he explains.[E] Graham has no plans for expansion, as he wants to keep the business as a rural craft.[F] Graham has now perfected over 100 original designs.

填空题Robotic Cones and Barrels A University of Nebraska professor has developed robotic cones and barrels (锥形路标和路障 ). 31 They can even be programmed to move on their own at any particular part of the day, said Shane Farritor, an assistant professor of mechanical engineering at Nebraska. For example, if workers arrived at 6 a. m, the cones could move from the side of the highway to block off the lane at that time. 32 "It just seems like a very good application for robots," Farritor said. "The robotic cones would also help remove people from hazardous jobs on the highway putting barrels and cones into place," Farritor said in a report on his creation. 33 This fund allowed Farritor to work on the project with graduate students at Nebraska and his assistant Steve Goddard. The robots are placed at the bottom of the cones and barrels and are small enough not to greatly change the appearance of the construction aides (辅助用具). "It would look exactly the same," Farritor said. "Normally there"s a kind of rubbery, black base to them. 34 " Farritor has talked with officials from the Nebraska Department of Roads about how the robots would be most useful to what they might need. The robots could come in handy following a slow-moving maintenance operation, like painting a stripe on a road or moving asphalt, where now the barrels have to be picked up and moved as the operation proceeds. "That way you don"t have to block off a 10-mile strip for the operation," Farritor said. While prototypes have been made, they are not in use anywhere. Farritor said he has applied for a patent and is considering what to do next. 35 He is also thinking about marketing the robots to roads departments and others across the country that may benefit from them. A. And they can return to the original place at the end of the day. B. He is thinking about starting a small business. C. Farritor was "Inventor of the Year" in 2003. D. Work on the idea began in 2002 using a National Academy of Sciences grant. E. We replace that with a robot. F. These robotic cones and barrels can move out of the way, or into place, from computer commands made miles away.

填空题1. The Great Wall of China Walls and wall building have played a very important role in Chinese culture. These people, from the dim mists of prehistory have been wall -conscious; from the Neolithic period (新石器时代) —when ramparts (防御土墙) of pounded earth were used--to the Communist Revolution, walls were an essential part of any village. (46) The name for "city" in Chinese (ch'eng) means wall, and over these walled cities, villages, houses and temples presides the god of walls and mounts, whose duties were, and still are, to protect and be responsible for the welfare of the inhabitants. (47) However, it is indeed a common mistake to perceive the Great Wall as a single architectural structure, and it would also be erroneous to assume that it was built during a single dynasty. For the building of the wall spanned the various dynasties, and each of these dynasties somehow contributed to the refurbishing and the construction of a wall, whose foundations had been laid many centuries ago. (48) Especially three of these states: the Ch'in, the Chao and the Yen, corresponding respectively to the modern provinces of Shensi, Shanzi and Hopei, over and above building walls that surrounded their kingdoms, also laid the foundations on which Ch'in Shih Huang Di would build his first continuous Great Wall. (49) Throughout the centuries many settlements were established along the new border. The garrison (驻军) troops were instructed to reclaim wasteland and to plant crops on it, roads and canals were built, to mention just a few of the works carried out. (50) Builders, garrisons, artisans, farmers and peasants left behind a trail of objects, including inscribed tablets, household articles, and written work, which have become extremely valuable archaeological evidence to the study of defense institutions of the Great Wall and the everyday life of these people who lived and died along the wall.A. Not only towns alld villages; the houses and the temples within them were somehow walled, and the houses also had no windows overlooking the street, thus giving the feeling of wandering around a huge maze (迷宫).B. All these undertakings greatly helped to increase the country' s trade and cultural exchanges with many remote areas and also with the southern, central and western parts of Asia the formation of the Silk Route:C. Thus a great and extremely laborious task such as constructing a wall, which was supposed to run throughout the country, must not have seemed such an absurdity (谬论).D. The construction of the Great Wall is responsible for a large number of deaths and a vast amount of destruction in various places.E. It was during the fourth and third centuryB.C. that each warring state started building walls to protect their kingdoms, both against one another and against the northern nomads (游牧民).F. The role that the Great Wall played in the growth of Chinese economy was an important on

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.

A man whose very name is synonymous with scientific genius, Einstein has come to represent {{U}}(46) {{/U}} the flowering of 20th century scientific thought that set the stage for the age of technology. "The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic, but technological-technologies {{U}}(47) {{/U}}," wrote theoretical physicist Stephen Hawking in a Time essay explaining Einstein's significance. "Clearly, no scientist better represents those advances than Albert Einstein. " Time chose as runner-up President Franklin Roosevelt to represent the triumph of freedom and democracy over fascism, and Mahatma Gandhi as an icon for a century when civil and human rights became crucial factors in global politics. "What we saw Franklin Roosevelt embodying the great theme of freedoms fight against totalitarianism, Gandhi personifying the great theme of individuals struggling for their rights, and Einstein being both a great genius and a great symbol of a scientific revolution that brought with it amazing technological advances {{U}}(48) {{/U}} ," said Time Magazine Editor Walter Isaacson. Einstein was born in Ulm, Germany in 1879. In his early years, Einstein did not show the promise of what he was to become. He was slow to learn to speak and did not do well in elementary school. He could not stomach organized learning and loathed taking exams. In1905, however, he was to publish a theory which stands as one of the most intricate examples of human imagination in history. In his "Special Theory of Relativity", Einstein described how the only constant in the universe is the speed of light. Everything else-mass, weight, space, even time itself-is a variable. And he offered the world his now-famous equation: energy equals mass times the speed of light squared-E=mc2. "Indirectly, relativity paved the way for a new relativism in morality, art and politics," Isaacson wrote in an essay {{U}}(49) {{/U}}. "There was less faith in absolutes, not only of time and space but also of truth and morality. " Einstein's famous equation was also the seed that led to the development of atomic energy and weapons. In 1939, six years after he fled European fascism and settled at Princeton University, Einstein, an avowed pacifist, signed a letter to President Roosevelt urging the United States to develop an atomic bomb before Nazi Germany did. Roosevelt heeded the advice and formed the "Manhattan Project" {{U}}(50) {{/U}}. Einstein did not work on the project. Einstein died in Princeton, New Jersey in 1955. A. explaining Times choices B. how he thought of the relativity theory C. more than any other person D. that secretly developed the first atomic weapon E. that flowed directly from advances in basic science F. that helped expand the growth of freedom

填空题下面的短文后有2项测试任务：(1) 第23～26题要求从所给的6个选项中第2、4、5、6每段选择1个最佳标题；(2) 第27～30题要求从所给的6个选项中每个句子确定一个最佳选项。 More Than 8 Hours Sleep Too Much of a Good Thing Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 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 failing 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. These findings, which DL 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. 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. 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 day-to-day functioning. Kripke found that people who slept between 9 and 10 hours each night were more likely to re port 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 a wake. "he said. A. Kripke's research tool B. Dangers of Habitual shortages of sleep C. Criticism on Kripke's report D. A way of overcoming insomnia E. Sleep problems of long and short sleepers F. Classification of sleep problems

填空题Changes of Museums (46) They are no longer places for the privileged few or for bored vacationers to visit on rainy days. (47) Some of the old, gray museums have been rebuilt, and the newer ones are open and modern in their architecture. Inside, there is modern lighting, color, and sound. Instead of displaying everything they own, museum directors show fewer objects and leave open spaces where visitors can gather and sit down. They also bring together in one display a group of objects drawn from various parts of the museum in an effort to represent the whole lifestyle of a region or a historical period. (48) More and more, museum 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 experence of operating a spaceship or a computer. He can experiment with glass-blowing and paper-making. (49) 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. (50) A. The purpose is not only to provide fun but also to help people feel at home in the world of science.B. Museums have changed.C. In one room, for instance, you may find materials, clothing, tools, cooking pots, furniture, and art works of a particular place and time.D. Instead of being places that one "should" visit, they are places to enjoy.E. There are open spaces that museums leave for visitors.F. Many museums have changed in appearanc

填空题 Parkinson's Disease 1. Parkinson's disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine. Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly and do what you want them to do. When you have Parkinson's, these nerve ceils break down. Then you no longer have enough dopamine, and you have trouble moving the way you want to. 2. No one knows for sure what makes these nerve cells break down. But scientists are doing a lot of research to look for the answer. They are studying many possible causes, including aging and poisons in the environment. Abnormal genes seem to lead to Parkinson's disease in some people. But so far, there is not enough proof to show that it is always inherited. 3. Tremor may be the first symptom you notice. It is one of the most common signs of the disease, although not everyone has it. More importantly, not everyone with a tremor has Parkinson's disease. Tremor often starts in just one arm or leg or only on one side of the body. It may be worse when you are awake but not moving the affected arm or leg. It may get better when you move the limb or you are asleep. In time, Parkinson's affects muscles all through your body, so it can lead to problems like trouble swallowing or constipation. In the later stages of the disease, a person with Parkinson's may have a fixed or blank expression, trouble speaking, and other problems. Some people also have a decrease in mental skills (dementia). 4. At this time, there is no cure for Parkinson's disease. But there are several types of medicines that can control the symptoms and make the disease easier to live with. You may not even need treatment if your symptoms are mild. Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctor will adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results. A．Tips for Patients with the Disease B．Common Treatment for the Disease C．Means of Diagnosis of the Disease D．Typical Symptoms of the Disease E．Possible Causes of the Disease F．Definition of Parkinson's Disease

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.
