This kind of surgery is called cosmetic surgery, and both men and women are turning to this treatment as a way of keeping their appearance young as well as keeping competitive (有竞争力的)in their jobs. Men especially are beginning to turn to face-lifts(面部拉皮手术), liposuction (taking fat out of the body), and implants(putting artificial parts into their bodies )to help them look younger. As companies downsize(缩编)and move younger employees into higher positions, older employees in their late forties and early fifties feel the need to look and act younger in order to stay competitive. These operations are not without dangers, however. One young woman had an eye operation to get rid of the bags under her eyes. She described, her experience as terrible. She said, "When he started cutting, I was fully awake. Even though he'd given me an injection near my eyes, I saw everthing." She went on to explain, "I knew I had to keep still because of what he was doing. He was scraping(刮)away fat underneath my eyes. It took about ten minutes. After he finished, I felt I couldn't walk. I was so faint. "Her troubles did not end after the operation for two weeks. Her eyes were swollen (肿胀的)and almost completely closed, and even dark glasses could not hide the side effects of the operation. Liposuction, taking fat out of the body, is probably the most popular cosmetic operation in the United States. It seems simple enough. First, a small cut is made over the place where the patient wants the fat removed. Next, a small pipe is put into the cut. A machine like a vacuum cleaner is then used to suck the fat out of the body. However, as one doctor explained, some problems can happen after the operation. He warned, "Irregular lumps and loose skin can result from this operation. If it is not evenly done, liposuction can produce a very lumpy result." Patients often must have more liposuction to correct the problem.

And with bunches of grapes swinging (摇滚) in the wind, the vineyards of southern France are getting ready to celebrate it. The yearly wine festival is held in honour of Bacchus, the Roman god of wine. It's a fun time with parties, music, dancing, big meals and, of course, lots of wine. French wine-making began more than 2,500 years ago. The world's oldest type of vine grows in France and always produces a good quality wine. Today France produces one fifth of the world's wine, and some of the most famous varieties. The top wine-producing areas are Bordeaux, Burgundy and the Loire Valley. Champagne, a drink used in celebrations, is named after the place where sparkling (有气泡的)wine was first produced in 1700. Wine is made from the juice of freshly picked grapes. It is the sugars that turn into alcohol. Traditionally, people used to take off their shoes and crush the grapes with their bare feet to bring out the juice. Nowadays, this practice is usually carried out by machines. Each wine producing region has its own character, based on its type of grapes and soil. The taste of wine changes with time. Until 1850, all French champagne was sweet. Now, both wine and champagne taste slightly bitter. The drink has always been linked with riches, romance and nobleness. Yet the French think of it in more ordinary terms. They believe it makes daily living easier, less hurried and with fewer problems. "All its links are with times when people are at their best, with relaxation, happiness, long slow meals and the free flow of ideas." wrote wine expert Hugh Johnson.

单选题{{B}}第三篇{{/B}} Barbie Dolls In the mid 1940's, the young ambitious duo Ruth and Elliot Handler, owned a company that made wooden pictures frames. It was in 1945 that Ruth and Elliot Handler joined with their close friend Harold Mattson to form a company would be named MATTEL, MATT for Mattson, and EL for Elliot. In the mid 1950's, while visiting Switzerland, Ruth Handler purchased a German Lilli doll. Lilli was a shapely, pretty fashion doll first made in 1955．She was originally fashioned after a famous cartoon character in the West German Newsletter, Build. Lilli is the doll that would inspire Ruth Handler to design the Barbie doll. With the help of her technicians and engineers at Mattel, Barbie was born. Ruth then hired Charlotte Johnson, a fashion designer, to create Barbie's wardrobe. It was in 1958 that the patent for Barbie was obtained. This would be a fashion doll unlike any of her time. She would be long limbed, shapely, beautiful, and only 11.5 inches tall. Ruth and Elliot would name their new fashion doll after their own daughter, Barbie. In 1959, the Barbie doll would make her way to the New York Toy Show and receive a cool reception from the toy buyers. Barbie has undergone a lot of changes over the years and has managed to keep up with current trends in hairstyles, makeup and clothing. She is a reflection of the history of fashion since her introduction to the toy market. Barbie has a universal appeal and collectors both young and old enjoy time spent and memories made with their dolls.

单选题Seeing the World Centuries Ago If you enjoy looking through travel books by such familiar authors as Arthur Frommer or Eugene Fodor, it will not surprise you to learn that travel writing has a long and venerable history. Almost from the earliest annals of recorded time individuals have found ready audiences for their accounts of journeys to strange and exotic locales. One of the earliest travel writers, a Greek geographer and historian named Strabo, lived around the time of Christ. Though Strabo is known to have traveled from east of the Black Sea west to Italy and as far south as Ethiopia, he also used details gleaned from other writers to extend and enliven his accounts. His multivolumed work Geography provides the only surviving account of the cities, peoples, customs, and geographical peculiarities of the whole known world of his time. Two other classic travel writers, the Italian Marco Polo and the Moroccan Ibn Battutah, lived in roughly the same time period. Marco Polo traveled to China with his father and uncle in about A. D. 1275 and remained there 16 or 17 years, visiting several other countries during his travels. When Marco returned to Italy he dictated his memoirs, including stories he had heard from others, to a scribe, with the resulting book Il milione being an instant success. Though difficult to attest to the accuracy of all he says, Marco"s book impelled Europeans to begin their great voyages of exploration. Ibn Battutah"s interest in travel began on his required Muslim journey to Mecca in 1325, and during his lifetime he journeyed through all the countries where Islam held sway. His travel book the Rihlah is a personalized account of desert journeys, court intrigues, and even the effect of the Black Death in the various lands he visited. In almost 30 years of traveling it is estimated that Ibn Battutah covered more than 75,000 miles.

单选题The Only Way Is Up Think of a modern city and the first image that comes to mind is the skyline. It is full of great buildings, pointing like fingers to heaven. It is true that some cities don"t permit buildings to go above a certain height. But these are cities concerned with the past. The first thing any city does when it wants to tell the world that it has arrived is to build skyscrapers. When people gather together in cities, they create a demand for land. Since cities are places where money is made, that demand can be met. And the best way to make money out of city land is to put as many people as possible in a space that covers the smallest amount of ground. That means building upwards. The technology existed to do this as early as the 19th century. But the height of buildings was limited by one important factor. They had to be small enough for people on the top floors to climb stairs. People could not be expected to climb a mountain at the end of their journey to work, or home. Elisha Otis, a US inventor, was the man who brought us the lift—or elevator, as he preferred to call it. However, most of the technology is very old. Lifts work using the same pulley system the Egyptians used to create the Pyramids. What Otis did was attach the system to a steam engine and develop the elevator brake, which stops the lift falling if the cords that hold it up are broken. It was this that did the most to gain public confidence in the new invention. In fact, he spent a number of years exhibiting lifts at fairgrounds, giving people the chance to try them out before selling the idea to architects and builders. A lift would not be a very good theme park attraction now. Going in a lift is such an everyday thing that it would just be boring. Yet psychologists and others who study human behavior find lifts fascinating. The reason is simple. Scientists have always studied animals in zoos. The nearest they can get to that with humans is in observing them in lifts. "It breaks all the usual conventions about the bubble of personal space we carry around with us—and you just can"t choose to move away," says workplace psychologist, Gary Fitzgibbon. "Being trapped in this setting can create different types of tensions," he says. Some people are scared of them. Others use them as an opportunity to get close to the boss. Some stand close to the door. Others hide in the comers. Most people try and shrink into the background. But some behave in a way that makes others notice them. There are a few people who just stand in a comer taking notes. Don"t worry about them. They are probably from a university.

单选题Mysterious Nazca Drawings One of the most mysterious archaeological spectacles in the world is the immense complex of geometrical symbols, giant ground-drawings of birds and animals, and hundreds of long, ruler-straight lines, some right across mountains, which stretch over 1,200 square miles of the Peruvian tablelands, at Nazca. Nazca was first revealed to modern eyes in 1926 when three explorers looked down on the desert from a hillside at dusk and briefly saw a Nazca line highlighted by the rays of the sun. But it was not until the Peruvian airforce took aerial photographs in the 1940s that the full magnificence of the panorama was apparent. Hundreds of what looked like landing strips for aircraft were revealed. There were eighteen bird-like drawings, up to 400 feet long; four-sided figures with two lines parallel; and long needle-like triangles which ran for miles. Among the many abstract patterns were a giant spider, a monkey, a shark, all drawn on the ground on a huge scale. The scale is monumental, but from the ground almost invisible and totally incomprehensible. The amazing fact about Nazca, created more than 1,500 years ago, is that it can only be appreciated if seen from the air. Many, therefore, regarded it as a prehistoric landing ground for visitors from outer space, but Jim Woodman, an American explorer, who was long fascinated by the mystery of Nazca, had a different opinion. He believed that Nazca only made sense if the people who had designed and made these vast drawings on the ground could actually see them, and that led him to the theory that the ancient Peruvians had somehow learned to fly, as only from above could they really see the extent of their handiwork. With this theory in mind, he researched into ancient Peruvian legends about flight and came to the conclusion that the only feasible answer was a hot-air balloon. To prove his theory, Woodman would have to make such a thing using the same fabrics and fibers that would have been available to the men of Nazca at the time. He started by gathering information from ancient paintings, legends, books and archaeological sites. After many attempts, Woodman built a balloon-type airship. It took him into the air, letting him have the sensation he had never had from viewing the same ground that he had seen many times. His flight was a modern demonstration of an ancient possibility.
