单选题New U.S. Plan for Disease Prevention Urging Americans to take responsibility for their health, Health and Human Services Secretary Tommy Thompson on Tuesday launched a $15 million program to try to encourage communities to do more to prevent chronic diseases like heart disease, cancer and diabetes. The initiative highlights the cost of chronic diseases—the leading causes of death in the United States—and outlines ways that people can prevent them, including better diet and increased exercise. "In the United States today, 7 of 10 deaths and the vast majority of serious illness, disability and health care costs are caused by chronic diseases," the Health and Human Services Department said in a statement. The causes are often behavior—smoking, poor eating habits and a lack of exercise. "I am convinced that preventing disease by promoting better health is a smart policy choice for our future," Thompson told a conference held to launch the initiative. "Our current health care system is not structured to deal with the escalating costs of treating diseases that are largely preventable through changes in our lifestyle choices." Thompson said heart disease and strokes will cost the country more than $ 351 billion in 2003. "These leading causes of death for men and women are largely preventable, yet we as a nation are not taking the steps necessary for US to lead healthier, longer lives," he said. The $15 million is slated to go to communities to promote prevention, pushing for changes as simple as building sidewalks to encourage people to walk more. Daily exercise such as walking can prevent and even reverse heart disease and diabetes, and prevent cancer and strokes. The money will also go to community organizations, clinics and nutritionists who are being encouraged to work together to educate people at risk of diabetes about what they can do to prevent it and encourage more cancer screening. The American Cancer Society estimates that half of all cancers can be caught by screening, including Pap tests for cervical cancer, mammograms for breast cancer, colonoscopies, and prostate checks. If such cancers were all caught by early screening, the group estimates that the survival rate for cancer would rise to 95 percent.

Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a quake 地震) in China in 1975 snakes awoke from their winter sleep early only to freeze to death in the cold air. All the unusual behavior, as well as physical changes in earth, alerted (提醒) Chinese scientists to the coming quake. They moved people aw/ay from the danger zone and saved thousands of lives., One task for scientists today is to learn exactly which types of animal behavior predict quakes. It is not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1979, for example, an Arabian horse became very nervous and tries to break out of his stall. The horse next to him, however, remained perfectly calm. It is also difficult sometimes to tell the difference between normal animal cahnness and "earthquake nerves". A zookeeper once told earthquake researchers that his cougar (美洲狮) had been acting strangely. It turned out that the cougar had a stomachache. A second task for scientists is to find out. exactly what kinds of warning the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can detect tiny changes in air pressure, gravity, or the magnetism (磁力) of earth. This extra sense probably helps animals predict earthquakes. A good example of this occurred with a group of dogs. They were closed in an area that was being shaken by a series of tiny earthquakes. Before each quake a low boomingsound was heard. Each sound caused the dog to bark (吠) wildly. The dogs began to bark during a silent period! A scientist who was recording the quakes looked at his machine. He realized that the dogs had reacted to a booming noise. They also sensed the tiny quake that followed it. The machine recorded both, though humans felt and heard nothing. In this case there was a machine to check what the dogs were sensing. Many times, however, our machines record nothing out of the ordinary, even though animals know a quake is coming. The animals might be sensing something we do measure but do not recognize as a warning. Discoveringwhat animals sense, and learning how they know danger signals, is a job for future.

单选题Norwich Norwich, the capital of the part of Britain known as East Anglia, has been in existence for more than two thousand years. It began as a small village beside the River Wensum. At the time of the Norman invasion in 1066 it had grown to become one of the largest towns in England. With two cathedrals and a mosque(清真寺), Norwich has long been a popular centre for various religions. The first cathedral was built in 1095 and has recently celebrated its 900th anniversary, while Norwich itself had a year of celebration in 1994 to mark the 800th anniversary of the city receiving a Royal Charter. This allowed it to be called a city and to govern itself independently. Today, in comparison with places like London or Manchester, Norwich is quite small, with a population of around 150,000, but in the 16th century Norwich was the second largest city of England. It continued to grow for the next 300 years and got richer and richer, becoming famous for having as many churches as there are weeks in the year and as many pubs as their are days in the year. Nowadays, there are far fewer churches and pubs, but in 1964 the University of East Anglia. was built in Norwich. With its fast-frowing student population and its success as a modern commercial centre (Norwich is the biggest centre for insurance services outside London), the city now has a side choice of entertainment: theatres, cinemas, nightclubs, busy cafes, excellent restaurants, and a number of arts and leisure centres. There is also a football team, whose colours are green and yellow. The team is known as "The Canaries (金丝雀)",though nobody can be sure why. Now the city's attractions include another important development, a modern shopping centre called "The Castle Mall". The people of Norwich lived with a very large hold in the middle of their city for over two years, as builders dug up the main car park. Lorries moved nearly a million tons of earth so that the roof of the mall could become a city centre park, with attractive water pools and hundreds of trees, but the local people are really pleased that the old open market remains, right in the heart of the city and next to the new development. Both areas continue to do good business, proving that Norwich has managed to mix the best of the old and the new.

单选题Dark Forces Dominate Universe The earth, moon, sun and all visible stars in the sky make up less than one percent of the universe. Almost all the rest is dark matter and dark energy, unknown forces that 1 astronomers. Observations in recent years have changed the basic 2 of how the universe evolved and have indicated how little is known about the major forces and substances that 3 our world. Astronomers now know that luminous (发光的) matter—stars, planets and hot gas—accounts 4 only about 0.4 percent of the universe. Non-luminous components, such as black holes and intergalactic (星系间的) gas, 5 up 3.6 percent. The rest is either dark matter, about 23 percent, or dark energy, about 73 percent. Dark matter, sometimes 6 "cold dark matter", has been known for some time. Only recently have researchers come to understand the key role it 7 in the formation of stars, planets and even people. "We 8 our very existence to dark matter," said physicist Paul Steinhardt and a co-author of a review on dark matter which 9 not long ago in the journal Science . "Dark matter dominated the structure 10 in the early universe," Steinhardt said. "For the first few billion years dark matter contained most of the mass of the universe. You can think of ordinary matter 11 a froth (泡沫) of an ocean of dark matter. The dark matter dumps (结成块) and the ordinary matter falls into it. That 12 to the formation of the stars and galaxies (星系)." Without dark matter, there would be virtually no structures in the universe. The nature of dark matter is 13 . It cannot be seen or detected directly. Astronomers know it is there because of its 14 on celestial (天体的) objects that can be seen and measured. But the most dominating force of all in the universe is called dark energy, a recently 15 power that astronomers say is causing the galaxies in the universe to separate at a faster and faster speed.

单选题 下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} {{B}} Football{{/B}} Football is, I suppose, the most popular game in England: one has only to go to one of the important matches to see this. Rich and poor, young and old, one can see them all there, shouting and cheering for one side or the other. One of the most surprising things about football in England to a stranger is the great knowledge of the game which even the smallest boy seems to have. He can tell you the names of the players in most of the important teams. He has photographs of them and knows the results of a large number of matches. He will tell you, with a great air of authority, who he expects will win such and such a match, and his opinion is usually as valuable as that of men three or four times his age. Most schools in England take football seriously--much more seriously than nearly all European schools, where lessons are all-important (至关重要的), and games are left for private arrangements. In England, it is believed that education is not only a matter of filling a boy's mind with facts in a classroom; education also means character training. One of the best ways of training character is by means of games, especially team games, where the boy has to learn to work with others for his team, instead of working selfishly(自私的) for himself alone. The school therefore arranges games and matches for its pupils. Football is a good team game, it is good exercise for the body, it needs skill and a quick brain, it is popular and it is cheap. As a result, it is the school's favorite game in the winter.

单选题Will Hillary Be the Next American President? Back in 1969, US President Richard Nixon confidently predicted: "In the next 50 years, we shall see a woman president, perhaps sooner than you think." Today, not too far off Nixon's deadline, America is looking at that possibility. Over the weekend, Hillary Rodham Clinton, wife of former president Bill Clinton, announced her run for 2008 presidency. US polls indicate that Americans feel comfortable with a female president. A New York Times survey found nearly all Americans saying they would vote for president if she were qualified. However, accepting the theoretical notion of a female leader is quite different from voting an actual woman. In fact, there is still widespread distrust of a woman in the top position. This is partly due to the biased thinking that women are weak on national security, though they might be strong on education and health care. This damages their prospects as a presidential contender. "There's still an inherent nervousness on the part of voters putting a woman in as the ultimate decision-maker. Control of the army and border security are sorts of traditionally male jobs," commented Amy Walter, an American campaign analyst. " That's where i think voters consciously or unconsciously have difficulties with women candidates." Women have held the top job in other major Western countries. In 1979, Britain elected Margaret Thatcher prime minister. Last year, Germany made Angela Merkel its first female chancellor. In the US, no woman has succeeded in being nominated as a presidential candidate. One woman did make the attempt: Elizabeth Dole. In 1999, she tried to get the Republican Party nomination. But Dole could only raise $ 5 million for her bid compared with the $56 million George W. Bush raised. So Barriers lie ahead for Hillary if she wants to make history by becoming the first female US president. With the Iraqi war underway, she'll find it even harder. "I don't feel that our society is ready for a woman president. The enemy we face does not respect females the same way we have come to see them as equals. If we were not in this war, I would support a woman president," said Chris Dildy, a computer engineering student.

单选题{{B}}第三篇{{/B}} Alexandre-Gustave Boenickhausen Eiffel was one of the 19th century's master builders. Wielding iron in new ways, he built bridges for the century's burgeoning railways in Europe, South America and Indochina. And after sculptor Frederic Auguste Bartholdi designed a colossal, 151-foot statue of copper sheets in 1871, he turned to France's magician of iron for its internal skeleton. Thus Eiffel was instrumental in creating two of the best-known monuments to liberty in the modern world—the Statue of Liberty and the Eiffel Tower, which was built to mark the centennial of the French Revolution. During the Nazi occupation in World War II, the tower' s personnel sabotaged the elevators to deprive the enemy of a view of Paris. (Hitler, who refused to climb the 1710 steps to the top, posed for his picture with the tower in the background. ) The city knew liberation was at hand on August 25, 1944, when two Parisians, braving bullets ricocheting through the girders, tore down the swastika and hoisted the tricolor. The tower illustrates Eiffel's genius for meticulous, innovative engineering. After he had set massive stone foundations beside the Seine, four giant leaning pillars, encompassing four acres, were joined 200 feet up at the first platform, an iron belt of trusses running from pillar to pillar. This belt had to be perfectly horizontal; if out of line by a hair, the structure would tilt disastrously at 1000 feet. Eiffel' s solution: hydraulic jacks embedded in each 440-ton column, enabling him to fine-tune its angle perfectly. Next, Eiffel deployed creeper cranes that climbed the tower as it grew, helping to hoist 15000 girders and 2.5 million rivets to the exact spot where needed. Astonishingly, the tower was completed in only two years and two months for three percent less than its $ 1.5-million budget, with no fatalities among the 250 workers. Thanks to Eiffel's mastery of design, the tower gives the wind little to seize. Seen from certain angles, the oddly beautiful tracery of intersecting iron beams appears almost transparent. The tower is so light that pressure on the foundations is only about 60 pounds per square inch—not much more than a well-fed gentleman exerts on the floor when sitting in a chair.

单选题Libraries A library is a place to find out about almost anything. In it there are mostly books. There are also pictures, papers, magazines, maps, tapes, and records. Special science and art shows, story hours, movies, plays, and contests may also be held there. Long long ago, a library had only books, and these were hard to get. Books could be written only by hand. There were so few that no one was allowed to take them out of the library. After the printing press was invented, books could be made faster. This helped libraries get more books. To borrow a book to take home today, a person just needs a library card. In many libraries a helper checks the book out. He or she stamps the card. The mark shows the date by which the book must be returned. If the book is returned late, the person must usually pay money, called a fine. In some libraries a computer has taken the place of stamping. Books in a library are put into a certain order to help people find what they want. All books about animals may be placed together. Or all stories written by the same person may be placed together. A big set of cards lists all the library"s books "in alphabetical order. It is called the card catalog. It tells where each of them can be found. People who live far in the country may find it hard to get to a library. For these people there are bookmobiles, which are large trucks filled with books. Each truck travels to many places. All the people have to do is meet the truck and choose the books they would like to read.
