单选题Three Ways to Become More Creative Most people believe they don't have much imagination. They are wrong. Everyone has imagination, but most of us, once we become adults, forget how to access it. Creativity isn't always connected with great works of art or ideas. People at work and in their free time routinely think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you. This technique involves taking unrelated ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object ,for example, a candle. Write down all the ideas/words associated with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the ideas to the job you have to do. So imagine you want to buy a friend an original present; you could buy him tickets to a match or take him out for the night. Imagine that normal limitations don't exist. You have as much time/space/money, etc. as you want. Think about your goal and the new possibilities. If, for example, your goal is to learn to ski(滑 雪),you can now practice skiing every day of your life(because you have the time and the money). Now adapt this to reality. Maybe you can practice skiing every day in December, or every Monday in January. Look at the situation from a different point of view. Good negotiators(谈判者)use this technique in business, and so do writers. Fiction writers often imagine they are the characters in their books. They ask questions: what does this character want? Why can't she get it? What changes must she make to get what she wants? What does she dream about? If your goal involves other people, put yourself "in their shoes". The best fishermen think like fish!

单选题 The Cherokee Nation 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. After the white man came, the Cherokees copied many of their ways. One Cherokee named Sequoyah saw how important reading and writing were 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 85 sounds 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 U.S. 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 (在枪品的威胁下) 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 What's Killing the Bats? First it was bees. Now it is bats. Biologists in America are working hard to discover the cause of the mysterious deaths of tens of thousands of bats in the northeastern part of the country. Most of the bats affected are the common little brown bats (Myotis lucifugus), but other species, such as the long-eared bat, the smallfooted bat, the eastern pipistrelle, and the Indiana bat have also been affected. In some caves, more than 90 percent of the bat populations have died. One possibility is disease. A white fungus (真菌) known as fusarium has been found on the noses of both living and dead bats. However, scientists don't know if the fungus is the primary cause of death, a secondary cause of death, or not a cause at all, but the result of some other conditions. Another possible cause is a lack of food. For example, bats typically eat a large number of moths (蛾), and in some states such as New York, the number of moths has been declining in recent years. If bats can't eat enough food, they starve to death. Still other scientists believe that global warming is to blame. Warmer temperatures in recent years have been waking up hibernating (冬眠) bats earlier than usual. If bats break their hibernation at the wrong time, they might not find their expected food sources. The weather might also turn cold again and weaken or kill the bats. Scientists might not agree on the causes of the bat die-off, but they do agree on the consequences. Bats are an important predator of mosquitoes; a single brown bat can eat 1,000 or more insects in an hour. They also eat beetles and other insects that damage plant crops. If there aren't enough bats, damage will be great from the insects they eat. While bats live a long time for their size—the little brown bat can live for more than 30 years—a female bat has only one baby per year, so bat populations grow slowly. Many bat species in the United States are already protected or endangered. How can you help? Do not disturb sleeping or nesting bats. If you discover bats that seem to be sick or that are dead, contact your local Fish & Wildlife Department with the details. However, be careful not to touch the animals.

单选题Cars have traditionally been wasteful beasts. Every time a drop of gas explodes inside a cylinder(气缸), the energy gets passed along from the piston(活塞)to the crankshaft(曲轴), flywheel (飞轮), gearbox, drivetrain, and axles(轮轴). By the time the wheels actually turn, four fifths of the original energy has disappeared. The electric Car goes a long way toward reducing wasted energy by replacing the internal - combustion engine with batteries. Even so, electric cars destroy about 60 percent of the energy because mechanical parts are stiu used to deliver energy from the batteries to the wheels. Lately, though, engineers have come up with a far more efficient way to accomplish the same task: by using magnets in the wheels. In traditional cars, four fifths of the original energy has been wasted by the timeA. the gas explodes inside the cylinder.B. the energy gets passed along from the piston to the crankshaft.C. the energy was delivered from the batteries to the wheels.D. the energy is finally passed to the wheels.

单选题The Family The structure of a family takes different forms around the world and even in the same society. The family's form changes as it adapts to changing social and economic influences. Until recently, the most common form in North America was the nuclear family, consisting of a married couple with their minor children. The nuclear family is an independent unit. It must be prepared to fend for itself, Individual family members strongly depend on one another. There is little help from outside the family in emergencies. Elderly relatives of a nuclear family are cared for only if it is possible for the family to do so. In North America, the elderly often do not live with the family; they live in retirement communities and nursing homes. There are many parallels between the nuclear family in industrial societies, such as North America, and of families in societies such as that of the Inuits, who live in harsh environments. The nuclear family structure is well adapted to a life of mobility. In harsh conditions, mobility allows the family to hunt for food. For North Americans, the hunt for jobs and improved social status also requires mobility. The nuclear family was not always the North American standard. In a more agrarian time, the small nuclear family was usually part of a larger extended family. This might have included grandparents, mother and father, brothers and sisters, uncles, aunts, and cousins. In North America today, there is a dramatic rise in the number of single-parent households. Twice as many households in the United States are headed by divorced, separated, or never- married individuals as are comprised of nuclear families. The structure of the family, not just in North America, but throughout the world, continues to change as it adapts to changing conditions.
