填空题A million years have been added to man"s evolutionary history. While anthropologist 1 estimated the age of Zinjanthrupus, the earliest toolmaking creature, 2 more than 600,000 years, a recent radioacitve dating measurement, based on volcanic rock samples 3 East Africa, where Zinjanthropus was 4 in 1959, now indicates that this 5 man may have roamed the earth 1, 750,000 years ago. The new date pushes evidence for the emergence of 6 making—one of the two essential attributes of humanity—back 7 the Pliocene Age, and it seems to fit 8 easily into the picture of human evolution than the 600,000 year figure. The Zinjanthropus was capable of walking erect, so that its hands were freed, and it had a brain large 9 to enable it to perform 10 simple tasks as making primitive cutting tools from quartz rock. The Zinjanthropus was not a 11 of the modern species, Homosapiens, but many anthropologists see in the creature a tube that could be very close to, if not actually in, the line of human evolution. The Zinjanthropus must be classified as a man albeit of a primitive type, because 12 animal species other than man both make and use tools. Anthropologists consider it probable that the larger brain and 13 intelligence of modern man evolved as primitive manlike creatures learned to use tools and to 14 by speech—the other essential of humanity. Such a course of 15 seems more reasonable starting nearly two million years ago than it would at the faster evolutionary pace required if the process started only a half million years ago.

填空题 The death of Enron Corp. founder Kenneth L. Lay early Wednesday raises the possibility that his conviction could be erased, complicating the federal government's effort to close the books on one of its most ambitious corporate fraud prosecutions. 66. ______. But when a defendant who pleaded not guilty dies before sentencing, as Lay did, in most cases the conviction is wiped out on the grounds that the defendant did not have the opportunity to appeal, legal experts said. "Fifth Circuit law in particular is clear on this point," Stanford University law professor Robert Weisberg said Wednesday, referring to the federal region that includes Houston. 67. ______. Only last week, federal prosecutors flied a motion with file Houston trial court seeking to recover $ 43.5 million that they said Lay had illegally obtained through Enron bonuses and a line of credit extended by the Houston energy company. Weisberg and other experts said that Lay's death might pose obstacles to that effort but that they expected the government to pursue restitution. "I foresee them fighting tooth and nail," Houston lawyer Philip H. Hilder said. The Justice Department declined to comment Wednesday. "We'll make a statement at the appropriate time, and the only thing we know is the appropriate time is not today," spokesman Bryan Sierra said. 68. ______. Coughlin said the main thrust of the case was to obtain hundreds of millions of dollars of additional compensation from the large banks and investment firms that remain defendants. Any assets retained by individual defendants such as Lay and Skilling were too small to make a material dent, Coughlin said. Skilling's sentencing probably will go forward as scheduled, his lead lawyer, Los Angeles- based Daniel M. Petrocelli, said Wednesday. 69. ______. "The president has described Ken Lay as an acquaintance, and many of the president's acquaintances have passed on during his time in office," Snow said in a morning news briefing. Lay's death ended his personal pursuit of one of his last publicly stated goals: clearing his name. "I firmly believe that I am innocent of the charges against me, as I have said from day one," Lay said in a statement posted on his website soon after the May 25 verdict. He added: "I will continue to work diligently with my legal team to prove that." 70. ______. According to the Pitkin County, Colo., coroner's office, coronary artery disease was the cause of the attack that killed Lay at a vacation home near Aspen. An autopsy showed evidence of a previous heart attack. However, friends left no doubt that the stress and humiliation of Lay's ordeal played a role in his death. "Some people will say he was as guilty as sin and this is God's judgment, but I for one will choose to remember the positive things about Mr. Lay," said the Rev. William Lawson, 78, founding pastor of Wheeler Avenue Baptist Church in Houston. A. Lay had been a confidant and political contributor to President Bush and his father, President George H. W. Bush. White House spokesman Tony Snow on Wednesday sought to downplay. B. Lay, who at age 64 succumbed to a massive heart attack at a rented Colorado vacation home, was found guilty by a federal jury in May along with former Enron Chief Executive Jeffrey K. Skilling of conspiracy and fraud. The two were star defendants in the notorious business scandal, which vaporized more than 4,000 jobs and billions of dollars in stockholders' investments. C. A conviction is the decision which is taken when someone is found guilty in a court of law. If a person is guilty, he has officially started to have committed a crime or offence. As a role, the guilty party should clearly have to pay the costs. When the person charged with a crime is stated guilty, he may plead guilty or not guilty. That is, he may officially say in a court of law that he has or has not committed the crime. D. Lay and Skilling were scheduled to be sentenced Oct. 23 and were widely expected to face prison terms of more than 20 years. They were convicted of lying to Enron employees and the public as part of a conspiracy to cloak the deteriorating financial condition of a company that claimed $101 billion in annual revenue at its 2000 peak and ranked No. 7 on the Fortune 500. E. A ruling wiping out Lay's conviction would leave him with a clean legal record, technically speaking, but it probably would do little to erase the taint of scandal. F. Lay's death will have little effect on the pending civil fraud lawsuit brought by the Securities and Exchange Commission, or on the massive consolidated lawsuit brought by former Enron employees and shareholders, scheduled for trial in Houston on Oct. 16, said Patrick J. Coughlin of San Diego law firm Lerach Coughlin Stoia Geller Rudman & Robbins, lead counsel in the case.

填空题 Biological rhythms make us a different person at 9 AM from we are at 3 PM. Here's a guide to when you work better, feel better, think better. Every fall, Jane, a young mother and part-time librarian, begin to eat more and often feels sleepy. Her mood is also darker, especially when she awakens in the morning; it takes all her energy just to drag herself out of bed. These symptoms persist until April, when warmer weather and longer days seem to lighten her cravings for food and sleep.66. ______. All living organisms, from mollusks to men and women, exhibit biological rhythms. Some are short and can be measured in minutes or hours. Others last days or months. The peaking of body temperature, which occurs in most people every evening, is a daily rhythm. The menstrual cycle is a monthly rhythm. The increase in sexual drive in the autumn — not in the spring, as poets would have us believe — is a seasonal, or yearly, rhythm. The idea that our bodies are in constant flux is fairly new — and goes against traditional medical training. In the past many doctors were taught to believe the body has a relatively stable, or homeostatic, internal environment. Any fluctuations were considered random and not meaningful enough to be studied. As early as the 1940s, however, some scientists questioned the homeostatic view of the body. Franz Halborg, a young European scientist working in the United States, noticed that the number of white blood cells in laboratory mice was dramatically higher and lower at different times of day. Gradually, such research spread to the study of other rhythms in other life forms, and the findings were sometimes startling. For example, the time of day when a person receives X-ray or drug treatment for cancer can affect treatment benefits and ultimately mean the difference between life and death. This new science is called chronobiology, and the evidence supporting it has become increasingly persuasive. Along the way, the scientific and medical communities are beginning to rethink their ideas about how the human body works, and gradually what had been considered a minor science just a few years ago. is being studied in major universities and medical centers around the world. There are even chronobiologists working for the National Aeronautics and Space Administration, as well as for the National institutes of Health and other government laboratories.67. ______. Because they are easy to detect and measure, more is known of daily — or circadian (Latin for "about a day") — rhythms than other types. The most obvious daily rhythm is the sleep-wake cycle. But there are other daily cycles as well, temperature, blood pressure, hormone levels. Amid these and the body's other changing rhythms, you are simply a different person at 9 AM from you are at 3 PM. How you feel, how well you work, your level of alertness, your sensitivity to taste and smell, the degree with which you enjoy food or take pleasure in music — all are changing throughout the day. Most of us seem to reach our peak of alertness around noon. Soon after that, alertness declines, and sleepiness may set in by mid-afternoon.68. ______. Long-term memory is different. Afternoon is the best time for learning material that you want to recall days, weeks or months later. Politicians, business executives or others who must learn speeches would be smart to do their memorizing during that time of day. If you are a student, you would be wise to schedule your more difficult classes in the afternoon, rather than in the morning. You should also try to do most of your studying in the afternoon, rather than late at night. Many students believe they memorize better while burning the midnight oil because their short-term recall is better during the wee hours of the morning than in the after- noon. But short-term memory won't help them much several days later, when they face the exam.69. ______. Your manual dexterity — the speed and coordination with which you perform, complicated tasks with your hard — peaks during the afternoon hours. Such work as carpentry, typing or sewing will be a little easier at this time of day. What about sports? During afternoon and early evening, your coordination is at its peak, and you're able to react the quickest to an outside stimulus like a baseball toward you at home plate. Studies have also shown that late in the day, when your body temperature is peaking, you will perceive a physical workout to be easier and less fatiguing — whether it actually is or not. That means you are more likely to work harder during a late-afternoon or early-evening workout, and therefore benefit more from it. Studies involving swimmers, runners, shot-putters and rowing crews have shown consistently that performance is better in the evening than in the morning. In fact, all of your senses — taste, sight, hearing, touch and smell—may be at their keenest during late afternoon and early evening. That could be why dinner usually tastes better to us than breakfast and why night lights irritate us. Even our perception of time changes from hour to hour. Not only does time seem to fly when you're having fun, but it also seems to fly even faster if you are having that fun in the late afternoon or early evening, when your body temperature is also peaking. While all of us follow the same general pattern of ups and downs, the exact timing varies from person to person. It all depends on how your "biological" day is structured and how much of a morning or night person you are. The earlier your biological day gets going, the earlier you are likely to enter — and exit — the peak times for performing various tasks. An extreme morning person and an extreme night person may have circadian cycles that are a few hours apart.70. ______. [A] Each of us can increase our knowledge about our individual rhythms. Learn how to listen to the inner beats of your body; let them set the pace of your day. You will live a healthier — and happier — life. [B] By contrast, we tend to do best on cognitive tasks — things that require the juggling of words and figures in one's head — during the morning hours. This might be a good time, say, to balance a checkbook. [C] With their new findings, they are teaching us things that can literally change our lives while helping us organize ourselves so we can work with our natural rhythms rather than against them. This can enhance our outlook on life as well as our performance at work and play. [D] Your short-term memory is best during the morning — in fact, about 15 percent more efficient than at any other time of day. So, students, take heed when face with a morning exam, it really does pay to review your notes right before the test is given. [E] After a time, the rhythms resynchronize and the problems disappear. But the various rhythms follow different time schedules in returning to normal. Thus, one rhythm may adjust within a matter of hours while another may require many days. [F] Joseph, a 48-year-old engineer for a Midwestern computer company, feels cranky early in the morning. But as the day progresses, he becomes friendlier and more accommodating.

填空题A = Beaumaris Castle B = Conwy Caste C = Harlech Castle D = Penrhyn Castle Which castle (s)... was seized by its enemies against whom it was designed to guard? 1 has the game name with another one built decades earlier? 2 are situated on a high place? 3 4 was built with an easy access to the dock? 5 inspired awe with its setting against striking mountains? 6 was furnished to the design of its architect? 7 has few equals in terms of building techniques ? 8 gives people a strong feeling of the Middle Ages? 9 was built for civilian use? 10 A Beaumaris Castle The king"s military architect, the brilliant James of St George, brought all his experience and inspiration to bear when building this castle, the biggest and most ambitious venture he ever undertook. In pure architectural terms, Beaumaris is the most technically perfect castle in Britain. Its ingenious and perfectly symmetrical concentric "walls within walls" design, involving no less than four successive lines of fortifications, was state of the art for the late 13th century. The stronghold stands at one end of Castle Street, inextricably linked with the history of the town. This was the "beau mareys" (fair marsh) that Edward chose for a castle and garrison town. From the outside, Beaumaris appears almost handsome. It does not rear up menacingly like other fortresses but sits amid a scenic setting overlooking mountains and the sea, partially surrounded by a water-filled moat, The "gate next-the-sea" entrance protected the tidal dock which allowed supply ships to sail right up to the castle. Beaumaris is endlessly fascinating. There is so much to see here—the 14 separate obstacles that any attacker would have to overcome, the hundreds of cleverly sited arrow-slits, and the deadly use of "murder holes" to defend entrances. B Conwy Castle A distinguished historian wrote of Conwy: "Taken as a whole, Conwy is incomparably the most magnificent of Edward I"s Welsh fortresses." The gritty, dark-stone fortress has the rare ability to evoke an authentic medieval atmosphere. The first time that visitors catch sight of the castle, commanding a rock above the Conwy estuary and demanding as much attention as the dramatic Snowdonia Mountain behind it, they know that they are in the presence of an historic site which still casts a powerful spell. Constructed by the English monarch between 1283 and 1287 as one of the key fortresses in his "iron ring" of castles to contain the Welsh, Conwy was built to prompt such a humbling reaction. There are no concentric "walls-within-walls" here, because they were not needed. Conwy"s massive military strength springs from the rock on which it stands and seems to grow naturally. Soaring curtain walls and eight huge round towers give the castle an intimidating presence undimmed by the passage of time. Conwy is the classic walled town. Its circuit of walls, over one and a quarter kilometers long and guarded by no fewer than 21 towers and three double-towered gateways, is one of the finest in the world. C Harlech Castle Spectacularly-sited Harlech Castle seems to grow naturally from the rock on which it is perched. Like an all-seeing sentinel, it gazes out across land and sea, keeping watchful eye over Snowdonia Mountain. The English monarch Edward I built Harlech in the late 13th century to fulfil this very role. It was one of the most formidable of his "iron ring" of fortresses designed to contain the Welsh in their mountain fastness. Ironically, in 1404 it was taken by Welsh leader Owain Glyndwr who proceeded to hold a parliament there. Looking seawards, Harlech"s battlements spring out of a near-vertical cliff-face, while any landward attackers would first have to deal with a massive twin-towered gatehouse. The sea, like 5nowdonia, is one of the keys to Harlech"s siting. Seaborne access was crucial in times of siege, and although the waters of Tremadog Bay have receded over the centuries, they may originally have lapped the cliffs beneath the castle. The fortress"s massive inner walls and towers grill stand almost to their full height. The views from its lofty battlements are truly panoramic, extending from the dunes at its feet to the purple mass of Snowdonia in the distance. Harlech, a combination of magnificent medieval military architecture and breathtaking location is an unmissable castle, a fact reinforced by its status as a World Heritage Inscribed site. D Penrhyn Caste Built for the wealthy Pennant family on the profits of Welsh slate and Jamaican sugar, Penrhyn Castle is an extravagant example of early 19th century neo-Norman architecture. It was built between 1820 and 1837 of Anglesey limestone, to the designs of Thomas Hopper. His patron, George Hay Dawkins (1764-1840), had taken the additional surname of Pennant on succeeding to the vast estates and fortunes of his cousin Richard Pennant, 1st Baron Penrhyn (1759-1808). The new castle engulfed another of the same name, built by Lord Penrhyn only 50 years earlier, and at the same time, the remains of the originally medieval manor house. Buried within its walls lie an earlier mock castle and a medieval hall, each a tribute to Penrhyn"s long and fascinating past, with links to the Welsh princes, a pirate and an Archbishop of York. Penrhyn"s architect Thomas Hopper, who also designed much of its furniture, filled the castle with intricate carvings, stained glass and handmade wallpapers. Walk through its rooms and see the one-ton slate bed made for Queen Victoria and a grand staircase that took ten years to build. On its walls hang one of the best art collections in Wales. The castle is surrounded by acres of parkland and wooded walks with beautiful plants.

填空题A Hydro power Introduction We have used running water as an energy source for thousands of years, mainly to grind com. The first house in the world to be lit by hydroelectricity was Cragside House, in Northumberland, England, in 1878. In 1882 on the Fox River, in the USA, hydroelectricity produced enough power to light two paper mills and a house. Nowadays there are many hydro-electric power stations, providing around 20% of the world's electricity. The name comes from“hydro”, the Greek word for water. How it works A dam is built to trap water, usually in a valley where there is an existing lake. Water is allowed to flow through tunnels in the dam, to turn turbines and thus drive generators. Advantages Once the dam is built, the energy is virtually free. No waste or pollution produced. Much more reliable than wind, solar or wave power. Water can be stored above the dam ready to cope with peaks in demand. Hydro-electric power stations can increase to full power very quickly, unlike other power stations. Disadvantages The dams are very expensive to build. Building a large dam will flood a very large area upstream, causing problems for animals that used to live there. Finding a suitable site can be difficult--the impact on residents and the environment may be unacceptable. Water quality and quantity downstream can be affected, which can have an impact on plant life. Is it renewable? Hydro-electric power is renewable. The Sun provides the water by evaporation from the sea, and will keep on doing so. B Nuclear power Introduction Nuclear power is generated using Uranium, which is a metal mined in various parts of the world. The first large-scale nuclear power station opened at Calder Hall in Cambria, England, in 1956. Some military ships and submarines have nuclear power plants for engines. How it works Nuclear power stations work in pretty much the same way as fossil fuel-burning stations, except that a“chain reaction”inside a nuclear reactor makes the heat instead. The reactor uses Uranium rods as fuel, and the heat is generated by nuclear fission. Neutrons smash into the nucleus of the uranium atoms, which split roughly in half and release energy in the form of heat. Carbon dioxide gas is pumped through the reactor to take the heat away, and the hot gas then heats water to make steam. Advantages Nuclear power costs about the same as coal, so it's not expensive to make. Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. Produces huge amounts of energy from small amounts of fuel. Produces small amounts of waste. Disadvantages Although not much waste is produced, it is very, very dangerous. It must be sealed up and buried for many years to allow the radioactivity to die away. Nuclear power is reliable, but a lot of money has to be spent on safety. Is it renewable? Nuclear energy from Uranium is not renewable. Once we've dug up all the Earth's uranium and used it. there isn't any more. C Solar power Introduction We've used the Sun for drying clothes and food for thousands of years. but only recently have we been able to use it for generating power. The Sun is 150 million kilometers away, and amazingly powerful. Just the tiny fraction of the Sun's energy that hits the Earth(around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over. How it works There are three main ways that we use the Sun's energy: Solar Cells(really called“photovoltaic”or“photoelectric”cells)that convert light directly into electricity. In a sunny climate, you can get enough power to run a 100W light bulb from just one square meter of solar panel. This was originally developed in order to provide electricity for satellites, but these days many of us own calculators powered by solar cells. Solar water heating, where heat from the Sun is used to heat water in glass panels on your roof. This means you don't need to use so much gas or electricity to heat your water at home. Solar Furnaces use a huge array of mirrors to concentrate the Sun's energy into a small space and produce very high temperatures. Advantages Solar energy is free-it needs no fuel and produces no waste or pollution. In sunny countries, solar power can be used where there is no easy way to get electricity to a remote place. Handy for low-power uses such as solar powered garden lights and battery chargers. Disadvantages Doesn't work at night. Very expensive to build solar power stations. Solar cells cost a great deal compared to the amount of electricity they'll produce in their lifetime. Can be unreliable unless you're in a very sunny climate. Is it renewable? Solar power is renewable. The Sun will keep On shining anyway, so it makes sense to use it. D Wind power Introduction We've used the wind as an energy source for a long time. The Babylonians and Chinese were using wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that. Wind power was used in the Middle Ages, in Europe, to grind corn. which is where the term“windmill”comes from. How it works The Sun heats our atmosphere unevenly, so some patches become warmer than others. These warm patches of air rise, other air blows in to replace them—and we feel a wind blowing. We can use the energy in the wind by building a tall tower, with a large propeller on the top. The wind blows the propeller round, which turns a generator to produce electricity. The more towers, the more wind, and the larger the propellers, the more electricity we can make. Advantages Wind is free, wind farms need no fuel. Produces no waste or greenhouse gases. The land beneath can usually still be used for farming. Wind farms Can be tourist attractions. A good method of supplying energy to remote areas. Disadvantages The wind is not always predictable—some days have no wind. Suitable areas for wind farms are often near the coast, where land is expensive. Can kill birds—migrating flocks tend to like strong winds. Can affect television reception if you live nearby. Is it renewable? Wind power is renewable. Winds will keep on blowing; it makes sense to use them.

填空题 Answer questions 71-80 by referring to the descriptions on 3 different clogs in me following magazine article. Note: Answer each question by choosing A, B or C and mark it on ANSWER SHEET 1. Some choices may be required more than once.{{B}}A = Labrador Retriever B = German Shepherd C = PoodleWhich dog,..{{/B}} {{B}}Labrador Retriever{{/B}} A retriever is a sporting dog that is specially trained for going after game that has been shot and bringing it back. The dog sees the game fall, or scents its location, and run swiftly to pick it up. Labrador Retriveer's hometown is Newfoundland, Canadas and was developed in England. Standard height for the males is 22.5 to 24, 5 inches (57-62cm); for the females, 21.5 to 23.5 inches (56-60 cm). Standard weight is 60 to 75 pounds (27-34 kg) for males and 55 to 70 pounds (25-32 kg) for females. The breed has a short, straight coat that may be black, yellow, or chocolate. The dog's special skills are flushing and retrieving and guiding the blind. It is subject to hip dysplasia. The "Lab" is deservedly one of the most esteemed family dogs. Obedient and quick to learn, alert as a watchdog, fine with children, gentle with everyone, fairly hardy, and, when it comes to coat care, even less bothersome than its rival, the golden retriever, the breed might well be the first choice of anyone who wants a largish dog that is not a guard dog. The Lab is apt to be somewhat rambunctious as a puppy, but it soon settles down to being a sweet-tempered paragon. However, it ought to have a lot of exercise even though, all too cheerfully for its own good, it will manage without it. Both Labs and golden retrievers are hurt badly by bullying. Looks-conscious prospective owners should be sure to find a Lab pup whose head has the correct appearance. Too many Labs have a narrow skull and muzzle that is properly associated with the breed. {{B}}German Shepherd{{/B}} German Shepherd is a large, strong, well-muscled dog developed in Germany from old breeds of herding dogs. Formal sponsorship of the breed began with the founding of the German dog club VDS in 1899. It was used for many years in Germany to guard flocks of sheep and cat- tie, and for police work. Though originally developed from herding dog, the German shepherd dog is now widely used as a companion dog, guard dog, guide dog for the blind, and military and police dog. It is not correct to call the dog a German police dog although many people do so. The desired heights for males at the top of the highest point of the shoulder blade is 24 to 26 inches (56-66 cm) and for females, 22 to 24 inches (56-61 cm). Males average between 75 and 95 pounds (27-34 kg). The German shepherd dog has a cleanly chiseled, strong head, moderately pointed ears, almond-shaped dark eyes, and strong teeth. Its double coat is medium length. The outer coat is dense, straight, harsh, and lies close to the body. The undercoat varies in thickness with the season. The tail is low-set and bushy and hangs in a slight curve at rest. Although you can see German shepherds in colors that vary from dark brown or blackish to a light shade of tan, the most common color is wolf-gray and tan, with black markings. In the United States strong, rich colors are preferred, and pale, washed-out Colors or blues or livers are considered serious faults. {{B}}Poodle{{/B}} Poodle is a highly intelligent breed of dog that is very popular as a pet and house dog. The poodle originated as a water retriever in Germany, which gave it its name, poodle, referring to water. It is often known as a "French" poodle because of its great popularity in France. It is an active and good-natured dog. There are now three varieties, which differ only in size: The standard, the oldest and largest variety, stands at least 15 inches(38 cm) at the highest point of the shoulders. The miniature stands 10 to 16 inches (25-38 cm) tall, and the toy is 10 inches (25cm) or less in height. All poodles have dense, wiry coats of thick, close curls. They may be any solid but most are black, brown, or white. Portions of its coat originally were shaved to facilitate swimming when it was used as a retriever. There are now several traditional poodle clips. A poodle under a year old may be in a "Puppy" clip, with its coat long except for its shaved face, throat, feet, and tail, has a pompon on the end. Those with unclipped hair are called corded poodles. Puppies are clipped medium-short when they are a few days old. Adult show dogs must have their hairs cut short with different styles, which differ different clips of the different parts of the dogs.

填空题 As international commerce grows, there is an amazing development which is expanding at ever-increasing rate--business on the Internet. One of the most arresting auction business is called eBay. Down at the local auction house in the city, you would normally find excited bidders raising their hands or nodding agreement as the auctioneer rattles off the prices for a set of bookshelves, heater or second-hand television set. Now the same cut and thrust of auction selling is drawing not the hundreds who cram into a crowded auction room, but millions of Internet surfers who visit eBay, the biggest online auction site, and others of similar style. 66. ______ For example, in one month that I looked at the colorful eBay site, these were numbers of items for sale in some of the major categories: Collectibles 684,473 Sports Memorabilia 269,051 Books, Movies, Music 267,324 Toys 242,155 67. ______ According to the eBay promotion, users can find the unique and the interesting on eBay--everything from chintz china to desks, teddy bears to trains, and furniture to figurines. So why do people come to eBay? As the leading person-to-person trading site, buyers trade on eBay because of the large number of items available. If you want it, somebody's probably selling it on eBay. Similarly, sellers are attracted to eBay to conduct business because eBay has the most buyers. There are over a million auctions happening on eBay every day. 68. ______ People tell us that they come for all the cool stuff they can get, but they stay, even after they finish their collection, for the fun people they meet at eBay. "Take your time, and get to know the eBay world" is their advice. So how do you make a bid and buy something at this auction? 69. ______ First I had to register my name, email address and password with eBay. So they can track the sales and make sure everybody is fair dealing. Remembering that bidding online is the same as buying or entering into a contract with the seller, I searched under guitars in the Musical Instruments section with my mouse clicking on the various pages. I had a good look at the seller's feedback record. If the person selling goods on eBay has tried to cheat, or back out of a deal, email users of eBay can write their own feedback comments, praising or criticizing the eBay seller, or bidder. Everyone can see what is going on. The eBay company can ban anyone who has not acted by the rules. 70. ______ The auction details were set out and the day the auction was to end (in one week's time). There was a nice picture of the guitar. I reviewed my bid of $ 20 to ensure that all the information was right and clicked on the button "Place Bid" Unfortunately I was notified that my bid was not the highest--someone else had bid more money, so I missed out. However, If I had put in the highest bid, the eBay website would have notified me that I was the highest bidder for the time being. When the auction ends, the highest bidder buys the goods.A. Among the special items for sale are an illustration of the winners from 84 Years of the USA Open Golf tournament, signed by the famous golfers, and framed. There is a Beatles Original Coin, especially minted for the first US tour in 1964 of the famous Liverpool pep music group. Furniture, new kitchen knives, guitar study programs, computers--you name it, eBay auction site has it, as people worldwide take advantage of the chance to sell their goods to the biggest market in the world--the cyberspace community of Internet watchers.B. This is a business that allows customers to buy and sell goods by offering them for sale, or bidding for items listed at the eBay website, as if they were at an auction. Currently, eBay has listed at its website 2.14 million items for sale in 1,627 categories. Each month the eBay site has 1.5 billion visitors who view the eBay pages, looking for bargains or working out how much to charge for that bed or unwanted radio they want to list for auction.C. I was looking for a guitar and this is what I did.D. There are not many stores in the world where they praise you as a good shopper or give you minus points in public if you are a bad payer. But this is the world of the Internet where the rules are being constructed as the system develops.E. According to an eBay spokesperson, eBay is more than just a place to trade. It's also a place to meet that one other person in the world who shares your passion for your own particular interest, whether it's stamps, war memorabilia, sporting goods, furniture or computer programs, for example.F. Then I was ready to bid. It does not cost any money to bid on items at eBay. Of course, if you win the auction, you must pay the seller directly, but you will not be charged anything by eBay.
