填空题Earth Angels 1. Joying Brescia was 8 years old when she noticed that cigarette butts (烟头) were littering her hometown beach in Isle of Palms, South Carolina. When she learned that it takes five years for the remains of a cigarette to disintegrate, she decided to take action. Joying launched a "No Butts on the Beach" campaign. She raised money and awareness about the need to keep the beaches dean. With the help of others, Joying also bought or received donations of gallon-size plastic ice cream buckets. The buckets were filled with sand, and placed at all public-access areas of the beach. The buckets allowed people to dispose of their cigarettes before hitting the beach. Two years later, Joying says the buckets are fun and the beach is nearly free of cigarette debris (残片). 2. People who live in or visit Steamboat Springs, Colorado have Carter Dunham to thank for a new state wildlife refuge that preserves 20 acres of marshland and many species of wildlife. Carter and other students wrote a management plan for the area around the Yampa River. The plan was part of a class project when Carter was a freshman at Steamboat Springs High School. Working with the Colorado Division of Wildlife, Carter and his classmates mapped the area and species of animals living there. They also made decisions about, among other things, where fences and parking areas should be built. 3. Barbara Brown and her friends collect oil. It started as a project for their 4H Club after one of the girls noticed her father using motor oil to kill weeds on their farm in Victoria, Texas. They did some research and discovered that oil can contaminate ground water—a real danger in rural areas where people live off the water on their land. The girls researched ways to recycle oil and worked with a local oil-recycling company on the issue. Now, the "Don"t Be Crude" program runs oil collection sites—tanks that hold up to 460 gallons—where people in the community can dispose of their oil. 4. Five years ago, 11-year-old Ryan Hreljac was a little boy with a big dream: for all the people in Africa to have clean drinking water. His dream began in the first grade when he learned that people were dying because they didn"t have clean water, and that as little as $70 could build a well. "We really take water for granted," says Ryan, of Kemptville, Ontario, in Canada. "In other countries, you have to plan for it." Ryan earned the first $70 by doing extra chores (零工), but with the help of others, he has since raised hundreds of thousands of dollars. His efforts led to the start of the Ryan"s Well Foundation, which raises money for clean water and health-related services for people in African countries and developing countries.

填空题 The Building of the Pyramids The oldest stone buildings in the world are the pyramids. {{U}} {{U}} 1 {{/U}} {{/U}}There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the "Step" pyramid and the "Bent" pyramid. Some of the pyramids still look much the same as they must have done when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modern buildings. {{U}} {{U}} 2 {{/U}} {{/U}}These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last for ever. {{U}} {{U}} 3 {{/U}} {{/U}}However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves. {{U}} {{U}} 4 {{/U}} {{/U}} Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly clear picture of them. One thing is certain: there must have been months of careful planning before they could begin to build. {{U}} {{U}} 5 {{/U}} {{/U}}You may think this would have been easy with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules had to be followed, and certain problems had to be overcome. A. The dry climate of Egypt has helped to preserve the pyramids, and their very shape has made them less likely to fall into ruin. B. It is practically certain that plans were made for the building of the pyramids because the plans of other large works have fortunately been preserved. C. The first thing they had to do was to choose a suitable place. D. Consequently, we are only able to guess at the methods used. E. Many people were killed while building the pyramids. F. They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet.

填空题The Joy of Living Alone More and more Americans are living alone. Some live alone because of divorce or the death of a partner. (1) According to a recent U.S. census (人口普查), 25 per cent of all households in the U.S. are made up of just one person. This is a dramatic change from the extended families of just a couple of generations ago. The typical person living alone is neither old nor lonely. (2) The majority of these people have chosen to live alone. They are responding to decreasing social pressure to get married and have a family. It's now socially acceptable, even fashionable, to live alone. As people get better jobs and become financially independent, it becomes possible for them to maintain a one-person household. (3) However, people who do get married are marrying at a later age and divorcing more often. The number one reason given by most people for living alone is that they simply enjoy doing what they want when they want to do it. "Living alone is a luxury," says Nina Hagiwara, 38. "Once you do it, you can't ever go back to living with others. " David C'Debaca, 46, agrees. (4) Children think that being grown up means being able to do exactly as they please. (5) The chance to discover whether that freedom is as wonderful as it sounds is a chance more and more Americans are taking. A．There's more pressure to get married nowadays. B．The growing number of women with good jobs has done much to increase the number of people living alone. C．However, even more people are living alone because they have chosen to. D．It seems that many grown-ups today are realizing that childhood dream. E．In fact, a quarter of the 23 million single people in the U.S. are under the age of 35. F．He says, "I like being by myself. /

Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.2 Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray-painting and assembling components.3 In Britain, robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.4 It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.5 It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan.6 The reliability of robots is measured in their M.T.B.F. or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small sample.7 The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. Once programmed, the robots can work more accurately and consistently than humans, who can get tired and bored.

填空题Caribbean Islands What would you see if you took a cruise to the Caribbean Islands? Palm trees and coconuts (椰子)? White beaches and clear, blue ocean? Colorful corals (珊瑚) and even more colorful fishes and birds? You bet. There are thousands of islands in the Caribbean Sea. They are famous for their warm, tropical climate and great natural beauty. The Caribbean Islands form a chain that separates the Caribbean Sea from the rest of the Atlantic Ocean. 1 Many of the islands were formed by the eruption (爆发) of ancient volcanoes (火山). Others are low-lying coral islands that gradually rose from the ocean. The Caribbean Islands are known by several names. 2 The explorer Christopher Columbus called the islands the Indies in 1492 because he thought he was near the coast of India. Later, Spain and France called the islands the Antilles. There are four large islands in the Caribbean Sea. 3 These four islands are often called the Greater Antilles. Together, they account for about 90 percent of the land area of the Caribbean Islands. The rest of the Caribbean Islands are much smaller. 4 You can see why pirates such as the famous Blackbeard sailed these waters. There are countless small islands to bury treasure or hide on. The weather of the Caribbean Sea is almost always warm and sunny. Sandy beaches line the coasts of many islands. 5 Many tourists arrive on cruise ships. A. But life on the Caribbean Islands is not always paradise. B. The earliest name used by Europeans is the Indies, later changed to the West Indies. C. They"re like a long necklace that stretches between North and South America. D. They are Cuba, Puerto Rico, Jamaica, and Hispaniola. E. This is why millions of tourists visit the islands each year. F. Some of these islands are no more than tiny slivers (小片) of exposed coral.

填空题 The Magic Io Personal Digital Pen Check out the io Personal Digital Pen launched by Logitech: It's a magic pen that can store everything you write and transfer it to your computer. And you don't have to lug a hand held device along with you for it to work. Logitech's technology works like this: The pen writes normally, using normal ballpoint pen ink. But while you are writing, a tiny camera inside the pen is also taking 100 snapshots per second of what you are doing, mapping your writing via a patchwork of minute dots printed on the paper. All this information-the movement of your pen on the paper, basically—is then stored digitally inside the pen, whether you are writing notes or drawing complex diagrams. You can store up to 40 pages worth of doodles in the pen's memory. As far as you are concerned, you are just using a normal pen. It is only when you drop the pen into its PC-connected cradle that the fun begins. Special software on your PC will figure out what you have done, and begin to download any documents you have written since the last time it was there. Depending on whether you have ticked certain boxes on the special notepad, it can also tell whether the document is destined to be an e-mail, a "to do" task, or a diagram to be inserted into a word-processing document. Once the documents are downloaded you can view them, print them out or convert them to other formats. The io Personal Digital Pen is a neat and simple solution to the problem of storing, sharing and retrieving handwritten notes, as well as for handling diagrams, pictures and other non-text doodling. You don't have to carry a laptop along with you. All you have to do is just whip out the pen and the special paper and you are off. It is a great product because it does not force you to work differently—walking around with a screen strapped to your arm, or carrying with you extra bits and pieces. The pen is light and works like a normal pen if you need it to, while the special notepads look and feel like notepads. The only strange looks will be from people who are curious why you are writing with a cigar. The io Personal Digital Pen also has potential elsewhere. FedEx, for example, is introducing a version of the pen so that customers can fill out forms by hand—instead of punching letters into cumbersome devices. Once that data is digital more or less anything can be done with it—transferring it wirelessly to a central computer, for example, or via a hand-phone. Doctors could transmit their prescriptions directly to pharmacies, reducing fraud; policemen could send their reports back to the station, reducing paperwork. A．A Friendly and Convenient Device B．Ways to Download the Stored Information C．Examples of Other Potential Applications of the Io Pen D．Customers' Passion for the Io Pen E．FedEx the First User of the Io Pen F．Working Principle of the Io Personal Digital Pen

填空题Goal of American Education Differences in American schools compared with those found in the majority of other countries lie in the fact that education here has long been intended for everyone—not just for a privileged elite. Schools are expected to meet the needs of every child, regardless of ability, and also the needs of society itself. (46) It surprises many people when they come here to find high schools offering such courses as typing, sewing, radio repair, computer programming or driver training, along with traditional academic subjects such as mathematics, history, and languages. (47) The underlying goal of American education is to develop every child to the utmost of his or her own possibilities, and to give each one a sense of civic and community consciousness. (48) Schools still play a large role in the community, especially in the small towns. The approach to teaching may seem unfamiliar to many, not only because it is informal, but also because there is not much emphasis on learning facts. (49) Students spend much time, learning how to use resource materials, libraries, statistics and computers. Americans believe that if children are taught to reason well and to research well, they will be able to find whatever facts they need throughout the rest of their lives. (50) This is America's answer to the searching question that thoughtful parents all over the world are asking themselves in the fast-moving time: "How can one prepare today's child for a tomorrow that one can neither predict nor understand?"A. Knowing how to solve problems is considered more important than the accumulation of facts.B. Students choose their curricula(课程) depending on their interests, future goals, and level of ability.C. Instead, Americans try to teach their children to think for themselves and to develop their own intellectual and creative abilities.D. This means that public schools offer more than academic subjects.E. Schools have traditionally played an important role in creating national unity and "Americanizing" the millions of immigrants who have poured into this country from many different backgr ounds and origins.F. Education is an enormous and expensive part of American life. Its size is matched by its variety.

填空题The Bilingual Brain When Karl Kim immigrated to the United States from Korea as a teenager, he had a hard time learning English. Now he speaks it fluently, and he had a unique opportunity to see how our brains adapt to a second language. As a graduate student, Kim worked in the lab of Joy Hirsch, a neuroscientist in New York. 1 They found evidence that children and adults don"t use the same parts of the brain when they learn a Second language. The researchers used an instrument called an MRI (magnetic resonance imaging) scanner to study the brains of two groups of bilingual people. 2 The other consisted of people who, like Kim, learned their second language later in life. People from both groups were placed inside the MRI scanner. This allowed Kim and Hirsch to see which parts of the brain were getting more blood and were more active. They asked people from both groups to think about what they had done the day before, first in one language and then the other. They couldn"t speak out loud because any movement would disrupt the scanning. Kim and Hirsch looked specifically at two language centers in the brain—Broca"s area, which is believed to control speech production, and Wernicke"s area, which is thought to process meaning. Kim and Hirsch found that both groups of people used the same part of Wernicke"s area no matter what language they were speaking. 3 People who learned a second language as children used the stone region in Broea"s area for both their first and second languages. People who learned a second language later in life used a different part of Broca"s area for their second language. 4 Hirsch believes that when language is first being programmed in young children, their brains may mix the sounds and structures of all languages in the same area. Once that programming is complete, the processing of a new language must be taken over by a different part of the brain. A second possibility is simply that we may acquire languages differently as children than we do as adults. Hirsch thinks that mothers teach a baby to speak by using different methods involving touch, sound, and sight. 5 A. But their use of Broca"s area was different. B. One group consisted of those who had learned a second language as children. C. How does Hirsch explain this difference? D. We use special parts of the brain for language learning. E. And that is very different from learning a language in a high school or college class. F. Their work led to an important discovery.

填空题Unlocking the Human Genome (基因组) 1．A．project to unlock secrets—what scientist could resist that challenge? This is what many scientists are doing as they work on the Human Genome Project. The aim of the project is to decode (破译) all of the some 100,000 genes in the human body. Scientists are using DNA fingerprinting techniques to do the decoding. 2．DNA．is the substance found in the chromosomes (染色体) of a cell. A chromosome is a chain of genes. Each gene carries a piece of genetic information. At any one moment in a cell, thousands of genes are turned on and off to produce proteins (蛋白质). The challenge for scientists is to find out what role each gene plays in protein production. At some point this decoding will be complete. Then scientists will have a map of an ideal genome, or a picture of the total genetic nature of a human being. The ideal genome is called a consensus (交感) genome. Everything works well in a consensus genome. 3．But no one in the world has a consensus genome. Everyone's genome is different from the ideal. These differences are referred to as genetic mutations (突变). Genetic mutations in a person's genome mean that the person has a greater than average chance of suffering from health problems. Some problems are not life-threatening. These would include things like colorblindness, or mild headaches. Other problems are serious, such as heart disease, or cancer. 4．It will take years to identify the role of each of the 100,000 genes. The short-term goal of the project is to find the physical and mental health problems a person is likely to encounter during his or her lifetime. The long-term goal is to have each person live a longer, healthier life.

填空题3. With Genetic Gift,2 Monkeys Are Viewing a More Colorful World Dalton and Sam are male squirrel monkeys, about a foot tall. (46) Dalton and Sam lead a more protected life in the laboratory of Jay and Maureen Neitz at the University of Washington, Seattle. Recently, the Neitzes endowed them with a new genetic gift: the ability to see the world with full color vision. Male squirrel monkeys have only two of the color pigments (色素) known as opsins (视蛋白), unlike people who have three. The Neitzes, with Katherine Mancuso and other colleagues, used the technique of gene therapy to introduce the gene for the missing red pigment into the cone cells of the monkeys' retinas (视网膜). (47) . It was somewhat surprising that the monkeys' brains could take advantage of a third opsin. The retina, however, seems to work by recording the difference between the signals from neighboring cones, the cells that detect color. (48) . New World male monkeys like Dalton and Sam are chromatically challenged because their ancestors split off from Old World primates before full color vision evolved. At the time of the split, primates had only two visual pigments, one that is particularly sensitive to blue light and another that responds best to either green or red, depending on which variant of the gene is inherited. (49) The gene for the red or green opsin was duplicated, allowing individuals to see red and green instead of just one or the other. New World monkeys never developed the duplicated gene, but many females have full color vision nevertheless. The reason is that the red/green opsin gene lies on the X chromosome, so females who inherit a different version from each parent have both red and green opsins along with the blue opsin on another chromosome (染色体). (50) A. But males, with only one X chromosome, inherit just one variant of the red/green opsin-the green in the ease of Dalton and Sam.B. Several months after the therapy, Dalton and Sam were aide to see a world in which red hues (颜色) were visible and oranges no longer looked like lemons, the researchers say in the current issue of Nature.C. Their ancestors lived by eating fruit and insects in the forest canopy (树荫) of Central and South America.D. After the split, which began with the opening of the Atlantic between Africa and Sunth America some 150 million years ago, the Old World primates benefited front a genetic accident.E. So the extra opsin gene given to Dalton and Sam would have changed the signal from affected cones and hence the message forwarded from the retina to the visual cortex in the brain.F. The monkey experiment would help researchers understand the circuitry used by the primate brain to analyze color.

During their first four minutes together, according to a book by Dr. Leonard Zunin. In his book, "Contact: The first four minutes," he offers this advice to anyone interested in starting new friendships:{{U}} (1) {{/U}}, A lot of people's whole lives would change if they'did just that. You may have noticed that average person does not give his undivided attention to someone he as just met.{{U}} (2) {{/U}},If anyone has ever done this to you, you probably did not like him very much. When we are introduced to new people, the author suggests, we should try to appear friendly and self-confident. In general, he says, "People like people who like themselves." On the other hand, we should not make the other person think we are too sure of ourselves. It is important to appear interested and sympathetic, realizing that the other person has his won needs, fears, and hopes. Hearing such advice, one might say, "But I'm not a friendly, self-confident person. That's not my nature. It would be dishonest for me to at that way." {{U}}(3) {{/U}}. We can become accustomed to any changes we choose to make in our personality. "It is like getting used to a new car. It may be unfamiliar at first, but it goes much better than the old one." But isn't it dishonest to give the appearance of friendly self-confidence when we don't actually feel that way? Perhaps, but according to Dr. Zunin, "total honest" is not always good for social relationships, especially during the first few minutes of contact. There is a time for everything, and a certain amount of play-acting may be best for the first few minutes of contact with a stranger. That is not the time to complain about one's health or to mention faults one finds in other people. It is not the time to tell the whole truth about one's opinions and impressions. {{U}}(4) {{/U}},For a husband and wife or a parent and child, problems often arise during their first four minutes together after they have been apart. Dr. Zunin suggests that these first few minutes together be treated with care. If there are unpleasant matters to be discussed, they should be dealt with later.The author says that interpersonal relations should be taught as a required course in every school, along with reading, writing, and mathematics.{{U}} (5) {{/U}}that is at least as important as how much we know. A. In reply, Dr. Zunin would claim that a little practice can help us feel comfortable about changing our social habits. B. Much of what has been said about strangers also applies to relationships with family members and friends. C. In his opinion, success in life depends mainly on how we get along with other people. D. Every time you meet someone in a social situation, give him your undivided attention for four minutes. E. He keeps looking over the other person's shoulder, as if hoping to find someone more interesting in another part of the room. F. He is eager to make friends with everyone.

填空题I"ll Be Bach Composer David Cope is the inventor of a computer program that writes original works of classical music. It took Cope 30 years to develop the software. Now most people can"t tell the difference between music by the famous German composer J.S. Bach (1685—1750) and the Bach-like compositions from Cope"s computer. It all started in 1980 in the United States, when Cope was trying to write an opera. 1 At first this music was not easy to listen to. What did Cope do? He began to rethink how human beings compose music. He realized that composers" brains work like big databases. First, they take in all the music that they have ever heard. 2 Finally, they make new music from what is left. According to Cope, only the great composers are able to create the database accurately, remember it, and form new musical patterns from it. Cope built a huge database of existing music. He began with hundreds of works by Bach. The software analyzed the data: it broke it down into smaller pieces and looked for patterns. It then combined the pieces into new patterns. 3 They weren"t good, but it was a start. Cope knew he had more work to do—he had a whole opera to write. He continued to improve the software. Soon it could analyze more complex music. He also added many other composers, including his own work, to the database. A few years later, Cope"s computer program, called "Emmy", was ready to help him with his opera. 4 Cope listened to the computer"s musical ideas and used the ones that he liked. With Emmy, the opera took only two weeks to finish. It was called Cradle Falling, and it was a great success! 5 Since that first opera, Emmy has written thousands of compositions. Cope still gives Emmy feedback on what he likes and doesn"t like of her music, but she is doing most of the hard work of composing these days! A. By developing a computer software, David Cope aimed to write an opera. B. Cope received some of the best reviews of his career, but no one knew exactly how he had composed the work. C. He was having trouble thinking of new melodies, so he wrote a computer program to create the melodies. D. The process required a lot of collaboration between the composer and Emmy. E. Before long, the program could compose short Bach-like works. F. Then they take out the music that they dislike.

填空题A Airport service B Training of pilots C Beginning period D Rapid growth in the US E Development F Competition

填空题These countries aim to exploit two contradictory facts: information can now be stored anywhere, but energy is most efficiently consumed close to the source. ______ Internet Villages International has joined up with Atlantis Resources, an engineer of ocean turbines, to develop technology that could power local data centers with energy from Scotland's rugged seas. Another company, Lockerbie Data Centres, is planning a green home and business community centered on a clean-energy data facility that runs on wind farms and a biomass plant.A. Thus several Scottish IT developers arc now planning nearly $3 billion in green data centers that tap into Scotland's clean-electricity grid, 20 percent of which comes from renewables like wind.B.

填空题Guessable Future When a magazine for high-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "radiate light" and "change color with the push of a button." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? Actually, (46) and the question was, "what will life be like in 1978?" The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict accurately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: (47) , but would have space for farms and fields. People would travel to work in "airbuses", large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard of". Does that sound familiar? If the expert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982".

New York—the Statue of Liberty, the skyscrapers, the beautiful shops on Fifth Avenue and the many theaters on Broadway. This is America’s cultural capital. It is also her biggest city, with a population of nearly 8 million. In the summer it is hot, hot, hot and in the winter it can be very cold. Still there are hundreds of things to do and see all the year round.2. Manhattan is the real center of the city. When people say “New York City,” they usually mean Manhattan. Most of the interesting shops, buildings and museums are here. In addition, Manhattan is the scene of New York’s busy night life. In 1605 the first Europeans came to Manhattan from Holland. They bought the island from the Native Americans for a few glass necklaces worth about $ 26 today.3. Wall Street in Manhattan is the financial heart of the USA. It is also the most important banking center in the world. It is a street of “skyscrapers”. These are those incredible, high buildings, which Americans invented, and built faster and higher than anyone else. Perhaps the two most spectacular skyscrapers in New York are the two towers of the New York World Trade Center. When the sun sets, their 110 floors shine like pure gold.4. Like every big city, New York has its own traffic system. Traffic jams can be terrible. It’s usually quickest to go by subway. The New York subway is easy to use and quite cheap. The subway goes to almost every corner of Manhattan. But it is not safe to take the subway late in night because in some places you could get robbed. New York buses are also easy to use. You see more if you go by bus. There are more than 30,000 taxis in New York. They are easy to see, because they are bright yellow and carry large TAXI signs. Taxis do not go outside the city. However, they will go to the airports. In addition to the taxi fare, people give the taxi driver a tip of 15 percent of the fare’s value.5. Central Park is a beautiful green oasis in the middle of New York’s concrete desert. It is surprisingly big, with lakes and woods, as well as organized recreation areas. New Yorkers love Central Park, and they use it all the time. In the winter, they go ice-skating, and in the summer roller-skating. They play ball, ride horses and have picnics. They go bicycling and boating. There is even a children’s zoo, with wild birds and animals.6. Along the east side of Central Park runs Fifth Avenue, once called “Millionaire’s Row.” In the 19th century, the richest men in America built their magnificent homes here. It is still the most fashionable street in the city, with famous department stores.7. Broadway is the street where you will find New York’s best known theaters. But away from the bright lights and elegant clothes of Broadway are many smaller theaters. Their plays an called “off-Broad-way” and are often more unusual than the Broadway shows. As well as many theaters, New York has a famous opera house. This is the Metropolitan, where international stars sing from September until April. Carnegie Hall is the city’s most popular concert hall. But night life in New York offers more than classical music and theater. There are hundreds of nightclubs where people go to eat and dance.
