单选题Acceptance of Chronic Illness For chronically ill patients, giving up the hope that they will get better may actually lead to more happiness, U.S. researchers suggest. "Hope is an important part of happiness, but there's a dark side of hope. Sometimes, if hope makes people put off getting on with their life, it can get in the way of happiness," Dr. Peter A. Ubel from the University of Michigan Health System said in a university news release. He and his colleagues studied patients who'd just had a colostomy (结肠造口术), which means their colons (结肠) were removed and they had to have howe1 (肠) movements in a pouch (小袋) outside the body. At the time of the surgery, some patients were told the procedure was reversible and they'd have a second operation in a few months to reconnect their bowels. Other patients were told the colostomy was permanent. The patients were followed for six months, and the researchers found that those without hope of regaining normal bowel function were happier than those with reversible colostomies. "We think they were happier because they got on with their life. They realized the cards they were dealt, and recognized that they had no choice but to play with those cards," Ubel said. "The other group was waiting for their colostomy to be reversed. They contrasted their current life with the life they hoped to lead, and didn't make the best of their current situation. " The study, published in the November edition of Health Psychology, also may explain why people whose spouse dies often recover better emotionally over time than those who get divorced, the researchers said. That's because people whose husband or wife dies have closure (结束), while those who get divorced may still have hope for some chance of making up, they explained.

单选题{{B}}第三篇{{/B}} William, who conquered England some 930 years ago, had wealth, power and a ruthless army. Yet although William was stupefyingly rich by the standard of his time, he had nothing remotely resembling a flush toilet. No paper towels, no riding lawn mower. How did he get by? History books are filled with wealthy people who were practically destitute compared to me, I have tripe-tracked storm window; Croesus did not. Entire nations trembled before Alexander the Great, but he couldn't buy cat food in bulk. Czar Nicholas Ⅱ lacked a compound-miter saw. Given how much better off I am than so many famous dead people, you'd think I'd be content. The trouble is that, like most people, I compare my prosperity with that of living persons: neighbors, high-school classmates, TV personalities. The covetousness I feel toward my friend Howard's kitchen is not mitigated by the fact that no French monarch ever had a refrigerator with glass doors. There is really no rising or falling standard of living. Over the centuries people simply find different stuff to feel grumpy about. You'd think that merely not having bubonic plague(腺鼠疫) would put us in a good mood. But no, we want a hot tub too. Of course, one way to achieve happiness would be to realize that even by contemporary standards the things I own are pretty nice. My house is smaller than the houses of many investment bankers', but even so it has a lot more rooms than my wife's and I can keep clean. Besides, to people looking back at our era from a century or two in the future, those bankers' fancy counter tops and my own worn Formica(福米加塑料桌面)will seem equally shabby. I can't keep up with my neighbor right now. but just wait.

单选题Jenny was a very ambitious and energetic person. She didn't have much in common with other girls in her school, however. She played football better than many boys, and unfortunately she made a rather bad impression on many of her teachers. Jenny just didn't act the way they thought a girl should. She studied at a university and later took a job as a typist. Although she was enthusiastic and did her best, she made many mistakes amt was poorly paid. She didn't want to be a typist anyway-she dreamed of becoming a pilot! Jenny moved to London, borrowed some money, and learned to fly. Nobody, however, wanted to hire a female pilot. She decided to fly alone to Australia to prove that she could fly as well as any man. Her parents lent her money to buy an airplane. Jenny set off on July 5, 1928. Her route took her over many places she dreamed of before. She was caught in a sandstorm and had to make an emergency landing in the desert. But she landed in India six days later. She had broken the record to India by two days. Over Burma she ran into a monsoon, and was able to save herself only by landing on a football field. She finally reached Australia. The plane propeller had been broken during her last landing, and she had to crash-land. But Jenny had proved that she could fly-and that a woman could do almost anything she really put her mind to. Jenny Johnson later married the pilot who had come to her rescue in Australia.

单选题Attempts to understand the relationship between social behavior and health have their origin in history. Dubos(1969) suggested that primitive humans were closer to the animals in that they, too, relied upon their instincts to stay healthy. Yet some primitive humans recognized a cause and effect relationship between doing certain thing and alleviating (减轻)symptoms of a disease or improving the condition of a wound. Since there was so much that primitive humans did not understand about the functioning of the body, magic became an integral component of the beliefs about the causes arid cutes of health disorders. So it is not surprising that early humans thought that illness was caused by evil spirits. Primitive medicines made from vegetables or animals were invariably used in combination with some form of ritual to expel harmful spirit from a diseased body. One of the earliest attempts in the western world to formulate(系统地阐述)principles of health care based upon rejection of supernatural phenomena is found in the work of the Greek physician Hippocrates. Little is known of Hippocrates who lived around 400 B. C., not even whether he actually authored the collection of books that bears his name. Nevertheless, the writings, attributed to him have provided a number of principles underlying modern practice. One of his most famous contributions, the Hippocratic Oath, is the foundation of contemporary medical ethics(道德). Among other things, it requires the physician to swear that he or she will help the sick, keep oneself from intentional wrong-doing or harm, and keep secret all matters to keep the doctor patient relation-ship. Hippocrates also argued that medical knowledge should be derived from an understanding of the natural sciences and the logic of cause and effect relation-ships. In this classic thesis, On Airs, Waters, and Places, Hippocrates pointed out that human wellbeing is influenced by the totality of environmental factors: living habits or lifestyle, climate, geography of the land, and the quality of air, and food. Interesting enough, concerns about our health and the quality of air, water, and places are still very much written in the twentieth century.

单选题Home Heating Central heating became popular only after the Civil War. Typically, coal-burning furnaces (火炉) fueled the early systems. Natural gas had developed into the leading fuel by 1960. Its acceptance resulted in part from its wide uses. Because it comes primarily from U.S. and Canadian fields, natural gas is also less vulnerable (脆弱的) than oil is to War. Oil remains the most important fuel in a few areas, such as New England. Electric heating dominates most areas with mild winters and cheap electricity, including the South and the Northwest. It was made popular at least in the South by the low cost of adding electric heating to new houses built with air-conditioning. Bottled gas, which is somewhat more expensive than utility gas, is the fuel of choice in rural areas not served by utility pipelines. Wood is the leading heating fuel in just a few rural counties. Home heating, which accounts for less than 7 percent of all energy consumed in the U.S., has had a commendable (值得赞扬的) efficiency record: from 1978 to 1997, the amount of fuel consumed for this purpose declined 44 percent despite a 33 percent increase in the number of housing units and an increase in house size. The U.S. Department of Energy, however, forecasts that energy used in home heating will rise by 14 percent over the next two decades. That rise is small considering an expected 21 percent increase in the number of houses and the trend toward larger houses. Natural gas and electricity will probably dominate the home heating market for the next two decades. Solar (太阳的) heating never became popular because of cost and limited winter sunlight in most areas; in 2000 only 47,000 homes relied on it.

单选题Looking to help the environment? Consider the following simple ideas. Turn off electrical devices when they"re not being used. Turning off, rather than leaving on stand-by, things like your TV and computer will save huge amounts of energy. With this, we can all help reduce the amount of carbon dioxide emitted into the earth"s atmosphere, thereby reducing pollution and global warming. Share your car. Rather than traveling to work alone, why not arrange ear-sharing with one or more of your friends or colleagues? To give you an example, if you drive a fashionable car, you will use more energy in a year than you would leaving your fridge open for seven years, or your TV on for thirty-two years! Imagine the savings if you shared your ear with 2, 3 or even 4 other people! Refuse junk mail. While we all complain about how much junk mail we get, we very rarely do anything about it. The mail continues to go straight from our letter-boxes into the garbage bin—with 99% of it not even opened. What can you do about this? There are various websites where you can register to receive no junk mail. As well as saving time, you"ll also be doing a lot for the environment. Each year, 100 million trees are used to produce junk mail. 250,000 homes could be heated with one day"s supply of junk mail. There are many other everyday changes you can make to help the environment. They will cost you nothing, and many will actually save you money! Why not give it a try? We can all help, if we really want to.
