填空题Natural Gas 1. Natural gas is produced from reservoirs deep beneath the earth"s surface. It is a fossil fuel, meaning that it is derived from organic material buried in the earth millions of years ago. The main component of natural gas is methane (甲烷). 2. The popularity and use of clean natural gas has increased dramatically over the past 50 years as pipeline infrastructure (基础设) has been installed to deliver it conveniently and economically to millions of residential, commercial and industrial customers worldwide. Today, natural gas service is available in all 50 states in the US, and is the leading energy choice for fueling American homes and industries. More than 65 million American homes use natural gas. In fact, natural gas is the most economical source for home energy needs, costing one-third as much as electricity. In addition to heating homes, much of the gas used in the United States is used as a raw material to manufacture a wide variety of products, from paint, to fibers for clothing, to plastics for healthcare, computing and furnishings. Natural gas is also used in a significant number of new electricity-generating power plants. 3. Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuels. When natural gas is burned, it produces mostly carbon dioxide (二氧化碳) and water vapor—the same substances emitted when humans exhale. Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted (燃烧), making natural gas the cleanest burning fossil fuel of all. The industry also is subject to substantial federal regulation in the areas of production and distribution, which help ensure it is provided to consumers safely and cleanly. 4. The United States consumes about one third of the world"s natural gas output, making it the largest gas consuming region in the world. The U. S. Department of Energy"s Energy Information Administration forecasts that natural gas demand will grow by more than 50 percent by 2025. 5. There are huge reserves of natural gas beneath the earth"s surface. The largest reserves of natural gas can be found in Russia, West and North Africa and the Middle East. LNG (液化天然气) has been produced domestically and imported in the United States for more than four decades. Today, the leading importers of LNG are Japan, Korea, France and Spain.

填空题Every Dog Has Its Say Kimiko Fukuda, a Japanese girl, always wondered what her dog was trying to say. Whenever she put on makeup, it would pull at her sleeve. 1 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." "I 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. 2 "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. 3 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. 4 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 translated as "Don"t come this way". 5 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. 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1. Moods, say the experts, are emotions that tend to become fixed, influencing one's outlook for hours, days or even weeks. That's great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely. 2. Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology(药物学)offers n abundance of tranquilizers(镇静剂), antidepressants and anti-anxiety drugs. What many people don't realize, however, is that scientists have discovered the effectiveness of several non-drug approaches to make you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don't head for the drug-store--try the following approach. 3. Of all the mood-altering self-help techniques, aerobic(增氧健身的)exercise seems to be the most efficient cure fox a bad mood. "If you could keep the exercise, you'd be in high spirits," says Kathryn Lance, author of Running for Health and Beauty. 4. Researchers have explained biochemical and various other changes that make exercise compare favorably to drugs as a mood-raiser. Physical exertion such as housework, however, does little. The key is aerobic exercise——running, cycling, walking, swimming or other repetitive and sustained activities that boost the heart rate, increase circulation and improve the body's utilization of oxygen. Do them for at least 20 minutes a session three to five times a week.

填空题You will find it hard to make friends with people ______.

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

填空题Understanding Autism Autism (孤独症) is a life-long developmental disability that prevents individuals from properly understanding what they see, hear, and otherwise sense. This results in severe problems of social relationships, communication, and behaviour. Individuals with autism have to painstakingly (费力地) learn normal patterns of speech and communication, and appropriate ways to relate to people, objects, and events, in a similar manner to those who have had a stroke. The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information coming in from the senses. There may be some imbalance of certain chemicals in the brain. Genetic (遗传的) factors may sometimes be involved. Autism may indeed result from a combination of several "causes". Most people with mental retardation (智力迟钝的) show relatively even skill development. Individuals with autism, however, typically show uneven skill development, with deficits (欠缺) in certain areas—most frequently in their ability to communicate and relate to others—and distinct skills in other areas. It is important to distinguish autism from mental retardation or other disorders, since diagnostic (诊断的) confusion may lead to inappropriate and ineffective treatment techniques. In general, individuals with autism perform best at jobs which are structured and involve a degree of repetition. Some people who have autism are working as artists, piano tuners, painters, farm workers, office workers, computer operators, dishwashers, assembly line workers, or employees of sheltered workshops or other sheltered work settings.

填空题Health Education1. Health education is the part of health care that is concerned with promoting healthy behavior. A person's behavior may be the main cause of a health problem, but it can also be the main solution. This is true for the teenager who smokes, the mother with the poorly nourished (营养) child, and the butcher (屠夫，卖肉的人) who gets a cut on his finger. By changing their behavior these individuals can solve and prevent many of their own problems.2. Health education does not replace other health services, but it is needed to promote the proper use of these services. One example of this is immunization (免疫) :scientists have made many vaccines (疫苗) to prevent diseases, but this achievement is of no value unless people to go receive the immunization.3. Health education encourages behavior that promotes health, prevents illness, cures disease, and contributes to recovery. The needs and interests of individuals, families, groups, organizations, and communities are at the heart of health education programs. Thus there are many opportunities for practicing health education.4. Health education is not the same thing as health information. Correct information is certainly a basic part of health education, but health education must also address the other factors that affect health behavior such as availability (可获性) of resouces, effectiveness of community leadership, social support from family members, and levels of self-help skills. Health education therefore uses a variety of methods to help people understand their own situations and choose actions that will improve their health. Health education is incomplete unless it encourages involvement and choice by the people themselves.5. Also, in health education we do not blame people if they do not behave in a healthy way. Often unhealthy behavior is not the fault of the individual. In health education we must work with families, communities, and even regional and national authorities to make sure that resources and support are available to enable each individual to lead a healthy life.

填空题Schooling and Education It is commonly believed in the United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. (46) . Education is much more open-ended and all-inclusive than schooling. Education knows no bounds. (47) It includes both the formal learning that takes place in schools and the whole universe of informal learning. The agents of education can range from a revered grandparent to the people, debating politics on the radio, from a child to a distinguished scientist. Whereas schooling has a certain predictability, education quite often produces surprises. (48) . People are engaged in education from infancy on. Education, then, is a very broad, inclusive term. It is a lifelong process, a process that starts long before the start of school, and one that should be an integral part of one's entire life. (49) . Throughout a country, children arrive at school at approximately the same time, take assigned seats, are taught by an adult, use similar textbooks, do homework, take exams, and so on. The slices of reality that are to be learned, whether they are the alphabet or an understanding of the workings of government, have usually been limited by the boundaries of the subject being taught. For example, high school students know that they are not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. (50) .A. The distinction between schooling and education implied by this remark is important.B. A man who has never been to school can also be well-educated.C. There are definite conditions surrounding the formalized process of schooling.D. It can take place anywhere, whether in the shower or in the job, whether in a kitchen or on a tractor.E. Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next.F. A chance conversation with a stranger may lead a person to discover how little is known of other religions.

填空题A Biological Clock Every living thing has what scientists call a biological clock that controls behavior. 1 It tells insects when to leave the protective cocoons and fly away, and it tells animals and human beings when to eat, sleep and wake. Events outside the plant and animal affect the actions of some biological clocks. Scientists recently found, for example, that a tiny animal changes the color of its fur because of the number of hours of daylight. In the short days of winter, its fur becomes white. 2 3 German scientists found that some kind of internal clock seems to order birds to begin their long migration flight twice each year. Birds prevented from flying become restless when it is time for the trip, but they become calm again when the time of the flight has ended. Scientists say they are beginning to learn which parts of the brain contain biological clocks. An American researcher, Martin Moorhead, said a small group of cells near the front of the brain seems to control the timing of some of our actions. 4 Scientists say there probably are other biological clock cells that control other body activities. Dr. Moorhead is studying how our biological clocks affect the way we do our work. For example, most of us have great difficulty if we must often change to different work hours. 5 Dr. Moorhead said industrial officials should have a better understanding of biological clocks and how they affect workers. He said such understanding could cut sickness and accidents at work and would help increase a factory"s production. A. These cells tell a person when to awaken, when to sleep and when to seek food. B. Inner signals control other biological clocks. C. The biological clock tells plants when to form flowers and when the flowers should open. D. It can take many days for a human body to accept the major change in work hours. E. The reason why there is a biological clock is not confirmed. F. The fur becomes gray brown in color in the longer hours of daylight in summer.

填空题How to Interview People Interviewing (采访) is one of those skills that you can only get better at. You will never again feel so ill at ease as when you try it for the first time, and probably you"ll never feel entirely comfortable trying to get from another person answers that he or she may be too shy to reveal. 6 The rest is instinct, which can all be learned with experience. The basic tools for an interview are paper and two or three well-sharpened pencils. But keep your notebook or paper out of sight until you need it. There"s nothing less likely to relax a person than the arrival of someone with a note-taking pad. 7 Take a while just to chat, judging what sort of person you"re dealing with, getting him or her to trust you. Never go into an interview without doing whatever homework you can. If you are interviewing a town official, know his voting record. If it"s an actor, know what plays he has been in. 8 Many beginning interviewers are afraid that they are forcing the other person to answer questions and have no right to inquire about his personal secrets. 9 Unless the person really hates being interviewed, he is delighted that somebody wants to interview him. Most men and women lead lives that are uninteresting, and they grasp any chance to talk to an outsider who seems eager to listen. This doesn"t necessarily mean that it will go well. In general you will be talking to people who have never been interviewed before, and they will get used to the process awkwardly, perhaps not giving you anything that you can use. 10 You will both even begin to enjoy it proof that you aren"t forcing your victim to do something he doesn"t really want to. A. Come back another day; it will go better. B. But at least half of the skill is mechanical. C. As one philosopher interviewed in the film notes, they lack irony. D. You will not be liked if you inquire about facts that you could have learned in advance. E. This fear is almost 100 percent unnecessary. F. Both of you need time to get to know each other.
