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}}Many Benefit from Cancer Organization{{/B}} 1. Do you know a child who survived leukemia? Do you have a mother, sister or aunt whose breast cancer was found early thanks to a mammogram? Do you have a friend or coworker who quit smoking to reduce their risk of lung cancer? Each of these individuals benefited from the American Cancer Society's research program. 2. Each day scientists supported by the American Cancer Society work to find breakthroughs that will take us one step closer to a cure. The American Cancer Society has long recognized that research holds the ultimate answers to the prevention, diagnosis and treatment of cancer. 3. As the largest source of nonprofit cancer research funds in the United States, the American Cancer Society devotes over $100 million each year to research. Since 1946, they've invested more than $2.4 billion in research. The investment has paid rich dividends: In 1946, only one in four cancer patients was alive five years after diagnosis; today 60 percent live longer than five years. 4. Investigators and health professionals in universities, research institutes and hospitals throughout the country receive grants from the American Cancer Society. Of the more than 1,300 new applications received each year, only 11 percent can be funded. If the American Cancer Society had more money available for research funding, nearly 200 more applications considered outstanding could be funded each year. 5. You can help fund more of these applications by participating in the American Cancer Society Relay for Life, a team event to fight cancer. More funding means more cancer breakthroughs and more lives being saved. To learn more, call Donna Hood, chair with the Neosho Relay for Life of the American Cancer Society at 451-4880.

填空题 Weight Worries May Start Early for Slim Women There is a range of reasons why thin women think they're too heavy, but the distorted body image may often have its roots in childhood, the results of a new study suggest. Researchers found that among more than 2,400 slim women they surveyed, nearly 10 percent thought they were too heavy. {{U}} {{U}} 1 {{/U}} {{/U}} According to the study authors, led by Dr. Susanne Kruger Kjaer of the Danish Cancer Society, Copenhagen, society's "ideal" female body is moving toward an underweight physique. {{U}} {{U}} 2 {{/U}} {{/U}} To investigate body image among thin women, the researchers gave questionnaires to 2,443 women ages 27 to 38 whose body mass index was at the low end of normal. {{U}} {{U}} 3 {{/U}} {{/U}} Overall, almost 10 percent of the women thought they were too heavy. Those who reported certain "severe life events" in childhood or adolescence, such as having a parent become ill or having their educational hopes dashed, were more likely than others to have a distorted body image. {{U}} {{U}} 4 {{/U}} {{/U}} In contrast, traumatic events in adulthood, such as serious illness or significant marital problems, were not related to poor body image, the researchers report. {{U}} {{U}} 5 {{/U}} {{/U}} A. The same was true of 4 women who started having sex or drinking alcohol when they were younger than 15 years old. B. Experiences' in childhood, including having an ill parent, or starting to drink or have sex at a particularly young age, were among the risk factors for having a distorted body image. C. "Our results indicate that the risk of being dissatisfied with (one's) own body weight may be established early in life," Kjaer and her colleagues write. D. Research suggests that many normal-weight women wish to weigh less. E. If worries have altered your appetite or weight, it will help to talk to someone about it. F. The women were asked about factors ranging from childhood experiences to current exercise habits.

These are not easy questions to answer. In the first place, no one is quite sure what intelligence is. We often say that intelligence means being able to solve problems. {{U}}(46) {{/U}}. For example, dogs and cats often find their way home from long distances. To do this they have to use their intelligence. They have to remember and think. But many birds find their way over long distances, too. They travel thousands of miles every year when they move from cool to warmer places. We do not know how they do this but we know that they do not use their intelligence. {{U}}(47) {{/U}}. Young birds are able to make these journeys without help as soon as they can fly. They are born with this ability. This is not intelligence. We call this 'instinct'. Often we cannot be sure whether an animal is acting intelligently or instinctively. When a dog hears a strange noise, it barks. This is instinct. It cannot stop itself from doing this. It does not really know why it is doing this. But supposing a house is on fire and the dog barks outside its master's bedroom until he wakes up, is the dog using its intelligence? {{U}}(48) {{/U}}. Often we cannot be sure. Many animals, however, can be taught to sole problems, especially when they are given rewards. Rats have been taught to press a lever to get food. Pigeons have been taught to peck a disc for the same reason. Even an octopus(章鱼) has been trained to know the difference between a square and an oblong (长方形)! Animals in circuses have been taught to do all sorts of tricks to amuse an audience. {{U}}(49) {{/U}}. It is saying, "if I do this, I will get a reward. Therefore I will do it." This may be thought of as a low kind of intelligence. Some animals, however, show a much higher kind of intelligence. They solve problems without any help. Chimpanzees, one of the ape family, are much more intelligent than other animals. A chimpanzee once did something even more intelligent. He did not have a stick. He had two short tubes. Neither of the tubes was long enough to reach the banana but one was wider than the other. He jammed the narrow tube inside the wider tube and in this way made one tube long enough to reach the banana {{U}}(50) {{/U}}.A Is it solving the problem by waking its master or is it simply barking instinctively because it is afraid?B Chimpanzees can solve certain problems without any help.C Some animals seem able to do this.D In all these cases we may say that an animal is using intelligence.E In other words, he did not simply use a tool, which itself is intelligent: he made a tool.F They do not remember places and directions and then make decisions.

Whenever she put on makeup, it would pull at her sleeve.{{U}} (46) {{/U}}When the dog barks, she glances at a small electronic gadget (装置). The following "human" translation appears on its screen: "Please take me with you." "1 realized that's how he was feeling," said Fukuda. The gadget is called Bowlingual, and it translates dog barks into feelings. People laughed when the Japanese toymaker Takara Company made the world's first dog-human translation machine in 2002. But 300,000 Japanese dog owners bought it.{{U}} (47) {{/U}} "Nobody else had thought about it," said Masahiko Kajita, who works for Takara. "We spend so much time training dogs to understand our orders; what would it be like if we could understand dogs?" Bowlingual has two parts.{{U}} (48) {{/U}}The translation is done in the gadget using a database (资料库) containing every kind of bark. Based on animal behaviour research, these noises are divided into six categories: happiness, sadness, frustration, anger, declaration and desire.{{U}} (49) {{/U}}In this way, the database scientifically matches a bark to an emotion, which is then translated into one of 200 phrases. When a visitor went to Fukuda's house recently, the dog barked a loud "bow wow". This is translated as "Don't come this way".{{U}} (50) {{/U}} The product will be available in US pet stores this summer for about US$120. It can store up to 100 barks, even recording the dog's emotions when the owner is away.A．A wireless microphone is attached to the dog's collar, which sends information to the gadget held by the owner.B．Nobody really knows how a dog feels.C．It was followed by "I'm stronger than you" as the dog growled (嗥叫) and sniffed (嗅) at the visitor.D．More customers are expected when the English version is launched this summer.E．Now, the Japanese girl thinks she knows.F．Each one of these emotions is then linked to a phrase like "Let's play", "Look at me", or "Spend more time with me".

填空题 Screen Test 1. Every year millions of women are screened with X-rays to pick up signs of breast cancer. If this happens early enough, the disease can often be treated successfully. According to a survey Australia, Canada, the U.S. and Spain, screen women under 50. 2. But the medical benefits of screening these younger women are controversial, partly because the radiation brings a small risk of inducing cancer. Also, younger women must be given higher doses of X-rays because their breast tissue is denser. 3. Researchers at the Polytechnic University of Valencia analysed the effect of screening more than 160,000 women at 11 local clinics. After estimating the women's cumulative dose of radiation, they used two models to calculate the number of extra cancers this would cause. 4. The mathematical model recommended by Britain's National Radiological Protection Board (NRPB) predicted that the screening programme would cause 36 cancers per 100,000 women, 18 of them fatal. The model preferred by the U.N. Scientific Committee on the Effects of Atomic Radiation led to a lower figure of 20 cancers. 5. The researchers argue that the level of radiation-induced cancers is "not very significant" compared to the far larger number of cancers that are discovered and treated. The Valencia programme, they say, detects between 300 and 450 cases of breast cancer in every 100,000 women screened. 6. But they point out that the risk of women contracting cancer from radiation could be reduced by between 40% and 80% if screening began at 50 instead of 45, because they would be exposed to less radiation. The results of their study, they suggest, could help "optimize the technique" for breast cancer screening. 7. "There is a trade-off between the diagnostic benefits of breast screening and its risks," admits Michael Clark of the NRPB. But he warns that the study should be interpreted with caution. "On the basis of the current data, for every 10 cancers successfully detected and prevented there is a risk of causing one later in life. That's why radiation exposure should be minimized in any screening programme." A. Harm Screening May Do to a Younger Woman B. Investing the Effect of Screening C. Effects Predicted by Two Different Models D. Small Risk of Inducing Cancers from Radiation E. Treatment of Cancers F. Factors That Trigger Cancers

填空题Acupuncture—Old Chinese Medicine For more than 4,000 years people in Asia have used acupuncture to treat illnesses. 1 Today acupuncture is also very popular in Europe, America and Australia. Acupuncture can control pain and sickness. It can also be used if you have a headache or back pain. Some doctors use acupuncture along with regular treatments for asthma, high blood pressure or stress. 2 Some people think that acupuncture can treat depression and even help people to stop smoking. Many patients feel more energy after a treatment, while others may feel more relaxed. People who practice acupuncture must take courses to learn how to do it correctly. 3 During treatment the patient lies down and needles are stuck into certain points of the body. There are hundreds of possible points and each one has a certain effect on the body. 4 For example, you stick a needle into the hand to treat problems with your stomach. Acupuncture needles are made of metal and about as thick as a human hair. They normally go less than one centimeter into the skin. When they are in the skin the acupuncturist may twist them or send electricity through them. The patients rest for a short time and then the needles are removed. Acupuncture normally doesn"t hurt. There is also a milder form of acupuncture called acupressure where you don"t need needles. Doctors use their fingers to press the points of the body. Chinese medicine teaches us that all acupuncture points are located along pathways called meridians. Each of these meridians carries energy, which the Chinese call "qi" to certain points of the body. If this "qi" gets blocked from an area the person will get sick or feel pain. Sticking needles into the correct points can help "qi" flow again and make the person well. Doctors today are not sure how acupuncture really works. They have not found any proof that these pathways of energy really exist. Some think that needles cause the body to produce pain killing substances. 5 Some also say that acupuncture only works because patients believe in it. A. Doctors have even used acupuncture to stop pain during an operation. B. Others think that the needles block pain signals that travel along the nerves to the brain. C. It is an old Chinese form of healing in which your skin is pierced with thin needles to relieve pain. D. In many places, especially outside of Asia, only doctors are allowed to perform acupuncture. E. The earliest written record of acupuncture is found in the Huangdi Neijing . F. The points can also be very far away from the place of pain.

填空题How to Argue with Your Boss 1. Before you argue with your boss, check with the boss"s secretary to determine his mood. If he ate nails for breakfast, it is not a good idea to ask him for something. Even without the boss"s secretary, there are keys to timing, don"t approach the boss when he"s on deadline; don"t go in right before lunch, when he is apt to be distracted and rushed; don"t go in just before or after he has taken a vacation. 2. If you"re mad, that will only make your boss mad. Calm down first. And don"t let a particular concern open the floodgates for all your accumulated frustration. The boss will feel that you think negatively about the company and it is hopeless trying to change your mind. Then, maybe he will dismiss you. 3. Terrible disputes can result when neither the employer nor the employee knows what is the problem the other wants to discuss. Sometimes the fight will go away when the issues are made clear. The employee has to get his point across clearly in order to make the boss understand it. 4. Your boss has enough on his mind without your adding more. If you can"t put forward an immediate solution, at least suggest how to approach the problem. People who frequently present problems without solutions to their bosses may soon find they can"t get past the secretary. 5. To deal effectively with a boss, it"s important to consider his goals and pressures. If you can put yourself in the position of being a partner to the boss, then he will be naturally more inclined to work with you to achieve your goals.

They belong to a group of drugs called anti-anxiety and hypnotic drugs. Such drugs formerly were referred to as depressants.2. There are two types of tranquilizers-anti-psychotic drugs and anti-anxiety drugs. Anti-psychotic drugs are used to treat patients with severe mental illness psychose. Antianxiety drugs are used to treat various emotional problems, particularly anxiety.3. Physicians prescribe anti-psychotic drugs to treat a mental illness that is characterized by illogical, unpredictable thinking. The drugs reduce the confusion and excitement experienced by the patient. Anti-anxiety drugs relax the muscles and reduce tension. They are prescribed mainly for the treatment of anxiety. Physicians also use anti-anxiety drugs to calm children who must undergo surgery.4 .Tranquilizers calm a person without causing much drowsiness if taken in a small enough dose. Larger doses may make the user sleepy as well as calmer. However, even the use of mild tranquilizers over a long period of time may make the user dependent on these drugs. Besides, some tranquilizers have undesirable side effects. They may cause muscle weakness and general fatigue. In addition, tranquilizers may cause drowsiness, especially if a person drinks alcoholic beverages before or after taking the drugs. A per- son should not drive a motor vehicle for several hours after taking a tranquilizer.5. Therefore, physicians usually prescribe a small doze of tranquilizers at a time. Patients who suffer from insomnia have to visit physicians from time to time for the medicine. Drugstores do not sell tranquilizers to people without the physician's prescription. You must have heard of stories about individuals taking an excessive dose of tranquilizers to commit suicide. Tranquilizers must be taken in accordance with the physician' s instructions.

填空题Breaking the News about Your Diagnosis1 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 (活检) 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 "1 was diagnosed with cancer" instead of saying "1 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 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 "1 don't know right now" or 'Tm 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.

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Seek Health and Wellness 1 Whether you are busy studying or starting clerkship, it is absolutely essential to maintain health and well-being throughout your medical career. Some ways are useful in trying to stay healthy and active. Hopefully you can take them! 2 Staring at a laptop screen for a prolonged (长时间) period of time not only dries out our eyes but also begins to take a toll on our efficiency. If you find yourself staring at the same slide for more than 15 minutes, take a nice walk outside! 3 Different types of nuts are great brain food! Nuts of any kind can easily be absorbed into your daily meals. They go great with milk and salads. To add in the nutritious value of nuts, they serve as a source of protein (蛋白质) while helping to raise HDL, the "good cholesterol" (胆固醇) in our bodies. 4 If you"re a coffee lover, try switching it up from time to time. Carbonated water is a good substitute every now and then. There are no calories, compared to regular sodas (碳酸饮料), and the carbonation adds a little fizz (嘶嘶声) that can help keep you awake and refreshed. 5 It"s easy to feel nervous about medical practice, but if you keep your mind focused on the big picture and acknowledge what you"ve done instead of what you haven"t, your mindset will take a turn for the greater good. Being confident and staying positive changes your mood and outlook making the workload more manageable. 6 We may have something called "puppy therapy". It"s important to have something that is "your thing", something that you enjoy doing that helps you connect with the outside world. That can be anything that can relax your mind and re-energize your body without taking a huge mass out of your busy day.

填空题Organ Donation and Transplantation 1. Organ donation (捐献) and transplantation (移植) refers to the process by which organs or tissues from one person are put into another person"s body. 2. The number of people needing a transplant continues to rise faster than the number of donors. About 3,700 transplant candidates are added to the national waiting list each month. Each day, about 77 people receive organ transplants. However, about 18 people die each day waiting for transplants that can"t take place because of the shortage of donated organs. 3. There are no age limits on who can be an organ donor. Newborns as well as senior citizens have been organ donors. If you are younger than 18, you must have a parent"s or guardian"s consent (同意). If you are 18 yearsold or older, you can show you want to be an organ and tissue donor by signing a donor card. 4. Many people think that if they agree to donate their organs, the doctor or the emergency room staff won"t work as hard to save their life. This is not true. The transplant team is completely separate from the medical staff working to save your life. The transplant team does not become involved with you until doctors have determined that all possible efforts to save your life have failed. 5. If you need an organ transplant, your doctor will help you get on the national waiting list. Your name will become part of a pool of names. When an organ donor becomes available, all the patients in the pool are compared to the donor. Factors such as blood and tissue type, size of the organ, medical urgency(紧急) of the patient"s illness, time already spent on the waiting list, and distance between donor and recipient(接受者) are considered.

It's about a wacky(古怪的)dad (who's also a scientist) who accidentally(偶然的) shrink's his kids with his homemade miniaturizing (使小型化) invention. Oops! The kids spend the rest of the movie as tiny people who are barely visible while trying to get back to their normal size. {{U}} (46) {{/U}}It takes place over years and may add up to only one inch or so off of their adult height (maybe a little more, maybe less), and this kind of shrinking can*t be magically reversed, although there are things that can be done to stop it or slow it down. But why does shrinking happen at all? {{U}} (47) {{/U}}As people get older, they generally lose some muscle and fat from their bodies as part of the natural aging process. Gravity (the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(椎骨), may break down or degenerate, and start to collapse into one another. {{U}}(48) {{/U}}. But perhaps the most common reason why some older people shrink is because of osteoporosis (骨质疏松症). Osteoporosis occurs when too much spongy(海绵) bone tissue (which is found inside of most bones) is broken down and not enough new bone material is made. {{U}}(49) {{/U}}. Bones become smaller and weaker and can easily break if someone with osteoporosis is injured. Older people—especially women, who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis. As years go by, a person with osteoporosis shrinks a little bit. Did you know that every day you do a shrinking act? You aren't as tall at the end of the day as you are at the beginning. {{U}}(50) {{/U}}. Don't worry, though. Once you get a good night's rest, your body recovers, and the next morning, you're standing tall again. A. They end up pressing closer together, which makes a person lose a little height and become shorter. B. That's because as the day goes on, water in the disks of the spine gets compressed (squeezed) due to gravity, making you just a tiny bit shorter. C. Over time, bone is said to be lost because it's not being replaced. D. Luckily, there are things that people can do to prevent shrinking. E. For older people, shrinking isn't that dramatic or sudden at all. F. There are a few reasons.

填空题Reinventing the Table An earth scientist has rejigged the periodic table to make chemistry simpler to teach to students. (46) But Bruce Railsback from the University of Georgia says he is the first to create a table that breaks with tradition and shows the ions of each element rather than just the elements themselves. "I got tired of breaking my arms trying to explain the periodic table to earth students," he says, criss-crossing his hands in the air and pointing to different bits of a traditional table. (47) But he has added contour lines to charge density, helping to explain which ions react with which. "Geochemists just want an intuitive sense of what's going on with the elements," says Albert Galy from the University of Cambridge (48) (49) He explains that sulphur, for example, shows up in three different spots one-for sulphide, which is found in minerals, one for sulphite, and one for sulphate, which is found in sea slat, for instance. He has also included symbols to show which ions are nutrients, and which are common in soil or water. (50) A. There have been many attempts to redesign the periodic table since Dmitri Mendeleev drew it up in 1871.B. Railsback has still ordered the elements according to the number of protons they have.C. "I imagine this would be good for undergraduates."D. Railsback has listed some elements more than once.E. And the size of element's symbol reflects how much of it is found in the Earth's crust.F. The traditional periodic table was well drawn.
