单选题Saving Money Where you save your money often depends on what you are saving for. If you are saving to buy a dictionary or to go to a concert, then probably keep your money somewhere in your room. If you are saving for a big purchase like a mountain bike or a school trip, where would you save your money? One place to save money is the bank. Putting your money in a savings account wilt help your money earn more money. If you put your money in a piggy bank (猪形储蓄罐), one year later you"ll still have the same amount of money you put in. If you put your money in a savings account, one year later, you"ll have more money. than you put in. Why? When you keep your money in a bank, your money earns interest. Interest is the amount of money a bank pays you to use your money. The bank uses your money (and the money of other people, too) to loan money to people and businesses. The bank will send you a statement several times a year. A bank statement tells you how much money there is in your account. It also tells you how much interest you have earned. If you leave your money in the bank, you can watch it grow! Another way you can save money is to buy a certificate of deposit or CD. If you have some money that you don"t need to use for a long time, this is a good way to make your money grow. You can buy a CD at a bank. You agree not to use the money for a certain period of time. That period might be from six months to five years. You can"t touch your money during that time. If you do, you must pay a penalty, or fee. Since the bank is using your money for that time period, it will pay you interest. You will earn more interest with a CD than in a savings account. Can you guess why? It"s because you promise to leave your money in the bank for a certain period of time. Banks pay different rates of interest. So, you may want to compare rates in newspaper ads before buying a CD.

单选题The Science of Persuasion If leadership consists of getting things done through others, then persuasion is one of the leader"s essential tools. Many executives have assumed that this tool is beyond their grasp, available only to the charismatic (有魅力的) and the eloquent. Over the past several decades, though, experimental psychologists have learned which methods reliably lead people to concede, comply, or change. Their research shows that persuasion is governed by several principles that can be taught and applied. The first principle is that people are more likely to follow someone who is similar to them than someone who is not. Wise managers, then, ask peers to help make their cases. Second, people are more willing to cooperate with those who are not only like them but who like them, as well. So it"s worth the time to uncover real similarities and offer genuine praise. Third, experiments confirm the intuitive truth that people tend to treat you the way you treat them. It"s sound policy to do a favor before seeking one. Fourth, individuals are more likely to keep promises they make voluntarily and clearly. The message for managers here is to get commitments in writing. Fifth, studies show that people really do defer to (服从) experts. So before they attempt to exert influence, executives should take pains to establish their own expertise and not assume that it"s self-evident. Finally, people want more of a commodity when it"s scarce; it follows, then, that exclusive information is more persuasive than widely available data.

单选题 Ford Abandons Electric Vehicles The Ford motor company's abandonment of electric cars effectively signals the end of the road for the technology, analysts say. General Motors and Honda ceased production of battery-powered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumers. Ford has now announced it will do the same. Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK, or Think Neighbor. It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1,700 carts have been sold so far in 2002. "The bottom line is we don't believe that this is the future of environment transport for the mass market," Tim Holmes of Ford Europe said on Friday. "We feel we have given electric our best shot." The Think City has a range of only about 53 miles and up to a six-hour battery recharge time. General Motors' EVI electric vehicle also had a limited range of about 100 miles. The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota RAV4 EV vehicle costs over $42,000 in the US. compared with just $17,000 for the petrol version. Toyota and Nissan are now the only major automanufacturers to produce electric vehicles. "There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on," Roger Higman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service. Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol—only engines, and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines "on vehicle emissions" in the US. However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 100,000 zero-emission and other low-emission vehicles in the state by 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.

单选题{{B}}第二篇{{/B}} {{B}}The Cherokee Nation{{/B}} Long before the white man came to America, the land belonged to the American Indian nations. The nation of the Cherokees lived in what is now the southeastern part of the United States. Aft6r the white man came, the Cherokees copied many of their ways. One Cherokee named Sequoyah saw how important reading and writing was to the white man. He decided to invent a way to write down the spoken Cherokee language. He began by making word pictures. For each word he drew a picture. But that proved impossible—there were just too many words. Then he took the 85sounds that made up the language. Using his own imagination and an English spelling book, Sequoyah invented a sign for each sound. His alphabet proved amazingly easy to learn. Before long, many Cherokees knew how to read and write in their own language. By 1828, they were even printing their own newspaper. In 1830, the US Congress passed a law. It allowed the government to remove Indians from their lands. The Cherokees refused to go. They had lived on their lands for centuries. It belonged to them. Why should they go to a strange land far beyond the Mississippi River? The army was sent to drive the Cherokees out. Soldiers surrounded their villages and marched them at gunpoint into the western territory. The sick, the old and the small children went in carts, along with their belongings. The rest of the people marched on foot or rode on horseback. It was November, yet many of them still wore their summer clothes. Cold and hungry, the Cherokees were quickly exhausted by the hardships of the journey. Many dropped dead and were buried by the roadside. When the last group arrived in their new home in March 1839, more than 4,000 had died. It was indeed a march of death.

单选题Almost Human? Scientists are racing to build the world's first thinking robot. This is not science fiction: some say they will have made it by the year 2020. Carol Packer reports. Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (机器人) which scientists have built at the Massachusetts Institute of Technology (MIT). Kismet is different from the traditional robots because it can show human emotions. Its eyes, ears and lips move to show when it feels happy, sad or bored. Kismet is one of the first of a new generation of androids—robots that look like human beings—which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old. The optimists (乐观主义者) say that by the year 2020 we will have created humanoids (机器人) with brains similar to those of an adult human being. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do? In the future, robots like Robonaut, a humanoid invented by NASA, will be doing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for us. In Japan, scientists are designing androids that will entertain us by dancing and playing the piano. Some people worry about what the future holds: will robots become monsters (怪物)? Will people themselves become increasingly like robots? Experts predict that more and more people will be wearing micro-computers, connected to the Internet, in the future. People will have micro-chips in various parts of their body, which will connect them to a wide variety of gadgets (小装置). Perhaps we should not exaggerate (夸大) the importance of technology, but one wonders whether, in years to come, we will still be falling in love, and whether we will still feel pain. Who knows?
