单选题Why is Valentine's Day, a holiday dedicated to the sweet bloom of love, celebrated in a cold month more suited to hats and gloves than to thoughts of love? "It's very mysterious," says Henry Kelly, director of the Center for Medieval and Renaissance Studies at the University of California. Kelly theorizes lovers everywhere can thank two guys from the 14th century: renowned poet Geoffrey Chaucer—famous for penning "The Canterbury Tales"—and a not-so-famous saint who went by the name of Valentine. In 1381, Chaucer was busy composing a poem in honor of the arranged marriage between England's Richard II and Anne of Bohemia. Chaucer was looking for just the right saint to honor on May 3, the day Richard II signed the papers of engagement to his Bohemia beauty. His search ended, Kelly guesses, when Chaucer learned that a Saint Valentine of Genoa had an honorary feast day on May 3. So he wrote the poem "The Parliament of Fowls" in the couple's honor. "The Parliament of Fowls" literally means "the meeting of birds" , says Kelly. "Chaucer dreamed up the idea that all birds chose their mates on May 3rd. When the spring brought its sunny smile back to the earth, it was easy to imagine the winged animals fluttering about and flirting with their lovers. " After Chaucer's death in ld00, Valentine's Day celebrations got pushed back to February. The date may have changed because the first song birds that traditionally warble(鸟鸣) after a winter tend to debut in mid-February. But the holiday that honors lovebirds everywhere with rhymed verse and colored candy hearts has not always been so popular. The very celebration of Valentine's Day has gone in and out of vogue. In the 16th century in Genoa you have it, but there is not much notice of it in other countries. The sweet-toothed holiday experienced renewed vigor in England just prior to 1800, and publishing companies came to the aid of tongue-tied lovers by distributing booklets of passages lovers could use to stir hearts. If they couldn't find the words in their hearts, companies figured, at least these Romeos could find some coins in their pocket to make their sweethearts happy. The celebration suffered a popularity plunge in the 19th century, but by the next century, Americans had rescued Valentine's Day from the trash heap, turning it into a commercial bonanza.

单选题{{B}}Passage Five{{/B}} Tattoos didn't spring up with the biker gangs and rock 'n' roll bands. They've been around for a long time and had many different meanings over the course of history. For years, scientists believed that Egyptians and Nubians were the first people to tattoo their bodies. Then, in 1991, a mummy was discovered, dating back to the Bronze Age of about 3,300 B.C. "The Iceman," as the specimen was called, had several markings on his body, including a cross on the inside of his knee and lines on his ankle and back. It is believed these tattoos were made in a curative (治病的) effort. Being so advanced, the Egyptians reportedly spread the practice of tattooing throughout the world. The pyramid-building third and fourth dynasties of Egypt developed international nations with Crete, Greece', Persia and Arabia. The art tattooing stretched out all the way to Southeast Asia by 2,000 B.C. Around the same time, the Japanese became interested in the art but only for its decorative attributes, as opposed to magical ones. The Japanese tattoo artists were the undisputed masters. Their use of colors, perspective, and imaginative designs gave the practice a whole new angle. During the first millennium A.D., Japan adopted Chinese culture in many aspects and confined tattooing to branding wrongdoers. In the Balkans, the Thracians had a different use for the craft. Aristocrats, according to Herodotus, used it to show the world their social status. Although early Europeans dabbled with tattooing, they truly rediscovered the art form when the world exploration of the post-Renaissance made them seek out new cultures. It was their meeting with Polynesian that introduced them to tattooing. The word, in fact is derived from the Polynesian word tattau, which means "to mark." Most of the early uses of tattoos were ornamental. However, a number of civilizations had practical applications for this craft. The Goths, a tribe of Germanic barbarians famous for pillaging Roman settlements, used tattoos to mark their slaves. Romans did the same with slaves and criminals. In Tahiti, tattoos were a rite of passage and told the history of the person's life. Reaching adulthood, boys got one tattoo to commemorate the event. Men were marked with another style when they got married. Later, tattoos became the souvenir of choice for globe-trotting sailors. Whenever they would reach an exotic locale, they would get a new tattoo to mark the occasion. A dragon was a famous style that meant the sailor had reached a "China station." At first, sailors would spend their free time on the ship tattooing themselves and their mates. Soon after, tattoo parlors were set up in the area, surrounding ports worldwide. In the middle of the 19th century, police officials believed that half of the criminal underworld in New York City had tattoos. Port areas were renowned for being rough places flail of sailors that were guilty of some crime or another. This is most likely how tattoos got such a bad reputation and became associated with rebels and criminals.

单选题{{B}}Passage Two{{/B}} Children live in a world in which science has tremendous importance. During their lifetimes it will affect them more and more. In time, many of them will work at jobs that depend heavily on science--for example, concerning energy sources, pollution control, highway safety, wilderness conservation, and population growth. As taxpayers they will pay for scientific research and exploration. And, as consumers, they will be bombarded (受到轰击) by advertising, much of which is said to be based on science. Therefore, it is important that children, the citizens of the future, become functionally acquainted with science--with the process and spirit of science, as well as with its facts and principles. Fortunately, science has a natural appeal for youngsters. They can relate it to so many things that they encounter--flashlights, tools, echoes, and rainbows. Besides; science is an excellent medium for teaching far more than content. It can help pupils learn to think logically, to organize and analyse ideas. It can provide practice in communication skills and mathematics. In fact, there is no area of the curriculum to which science cannot contribute, whether it is geography, history, language arts, music, or art! Above all, good science teaching leads to what might be called a "scientific attitude". Those who possess it seek answers through observing, experimenting, and reasoning, rather than blindly accepting the pronouncements of others. They weigh evidence carefully and reach conclusions with caution. While respecting the opinions of others, they expect honesty, accuracy, and objectivity and are on guard against hasty judgments and sweeping generalizations. All children should be developing this approach to solving problems, but it cannot be expected to appear automatically with the mere acquisition of information. Continual practice, through guided participation, is needed.

单选题Why are American scholars worried about education today?

单选题He is a rare celebrity scientist. He's even had a TV cameo role (小角色) in Star Trek in which he plays poker with scientific icons (偶像)Sir Isaac Newton and Albert Einstein. Yet when asked about comparisons between himself and the two scientists, he calls it all "media hype (炒作)." Once asked how he felt about being labeled the world's smartest person, he responded: "It is very embarrassing. It is rubbish, just media hype. They just want a hero, and I fill the role model of a disabled genius. At least I am disabled, but I am no genius. " Hawking has ALS or Lou Gehrig's disease, a neuromuscular disease that progressively weakens muscle control. He gets around in a wheelchair, and after completely losing the use of his vocal chords in an operation to assist his breathing in 1985, he communicates through a computer. A speech synthesizer "speaks" for him after he punches in what he wants to say, selecting words in the computer software by pressing a switch with his hand. Unfortunately, it makes him sound like he has an American accent, he says. Despite his humorous, self-effacing manner, Hawking is one of the world's leading theoretical physicists. Many consider him to be the most brilliant since Einstein. Since 1979, he's held the post of Lucasian professor of mathematics at Cambridge University—which was once held by Isaac Newton no less—and has twelve honorary degrees. He's also a best-selling author. His book, A Brief History of Time ,has been translated into 33 languages and has sold nine million copies. For much of his academic life, Hawking has been among a group of theoretical physicists searching for a "theory of everything'—one unified scientific theory that explains the big cosmological questions like How did the universe begin? Why is the universe the way it is? and How will it end ? You are probably familiar with the existing theories, such as the Big Bang theory. However, these theories are inconsistent with each other. So Hawking—among a group of theoretical physicists—has been on a quest to come. up with a theory of quantum (量子)gravity that would incorporate these theories—the theory of everything (TOE)—which would solve the problem of what caused the universe to start expanding. How successful have the world's leading cosmologists been? Hawking predicts we'll have the TOE in the next 20 years.
