单选题A half hour before test time, I was afraid to look in the mirror. But I had to assess the damages. After all, there were cute guys in this class. Granted, they would be worrying more about the final than what I looked like, and that was my hope at this point. The first things I saw were my own bloodshot eyes. Where was that Visine.'? My hair looked like Attila the Hun ad spent the night camping in it. Well, I'd pull it back into a ponytail and take the tangles out later. And then I saw it. It was a huge swelling on the front of my chin that had to be the size of a small golf hall. Surely I was hallucinating from lack of sleep. I had never seen anything like that be- fore, I'd heard of people getting hives from nerves. But a single hive, on the front of my face? I gingerly touched it. A hard swelling met my curious fingertips. What had caused this? The pizza I'd consumed at midnight or the mountain Dew I'd consumed at two and four and six in the morning? Perhaps it was the Cap's Crunch at three or the candy bar at five. My stomach had a strict policy. If I was going to keep it up all night, it insisted on being fed. How was I going to cover this up? I rummaged through all my toiletries until I found my lone bandage, put there for emergencies. Well, this qualified as one. Oh no, that looked really stupid. How embarrassing. Oh well, no time to do anything else about it now. My philosophy final was waiting for me. My beleaguered brain had tried all night to grasp the arguments of different philosophies so that I could write them down on the essay test this morning. I loved to hear our philosophy professor in class. I could follow the arguments when he discussed them, but trying to formulate them on my own just wasn't happening. Perhaps the bump was the result of stress. I had to pass this final or I would fail the class. And I couldn't fail the class, or I would have to take the college's summer school sessions. And I couldn't go to summer school be- cause I needed to work to help pay for next fall's tuition. Swallowing the last gulp of fiat Mountain Dew, I headed for class. I picked a seat that didn't directly face the clock. That would only make me more nervous, and God knew I had already used up my adrenaline(肾上腺素)supply. Dr. Wennberg passed out the essay books while explaining the roles we would have exactly one hour. My two pencils in hand, I waited for the signal. "Begin." I closed my eyes took a deep breath and said a prayer "Please, God, help me remember all that I' ye studied for this test." I looked over the questions. I could do this. I had to do this. I began writing. Twenty minutes had gone by. I had been writing as fast as I could before I forgot the information. So far so good. But my eyes were so tired. They hurt so badly. They felt so heavy. I' d just rest them for a minute. I leaned my puffy chin on my hand. Someone sneezed. I came to with a start. What? I'd fallen asleep? I'd never done that before in a final! Oh no! Fearfully, I looked at the clock. Only ten minutes left? I'd slept a half hour? Oh no ! I thought I'd used up all my adrenaline, but 1 was wrong. I broke out in a cold sweat. What could I do in ten minutes7 Think, I must think. I need a plan. I'm doomed. No, think. I began writing as fast as I could to finish the questions. I stared at the last blank page of the essay test booklet with its nearly ruled lines. Dare 17 I had nothing to lose. I still had two minutes. I wrote Dr. Wennberg.! told him how sorry I was. How I'd stayed awake all night to study because this was important to me, only to fall asleep during the exam. How I'd really wanted to do better I asked for mercy. One week later, I stood in front of the test board where the results would be posted. The mysterious swelling on my chin had gone away with sleep, but I touched my fingers to my chin nervously, It wasn't coming back, was it? I stood awaiting my fate. The secretary came out and pinned a paper to the board. I scanned down the list of names, looking for my final class grade. There it was; a C-minus. Tears filled my eyes. I looked again. I had passed I was sure I hadn't deserved that. But I wasn't about to argue ! Dr. Wennberg had shown mercy. It was one philosophy lesson I' ye never forgotten.

单选题1 Scientists now tend to agree that the noise level for potential hearing loss begins at about 70 decibels. Some of them are very concerned because normal daily life often exposes people to noise levels of about 70 decibels even inside their homes. Cities have always been noisy, but noise is now spreading to areas that were quiet just a few years ago. Clearly, something must be done or noise will seriously and permanently maim the population. Fortunately, the knowledge and methods to control noise already exist. As a matter of fact, this is one instance where the knowledge of control methods exceeds the knowledge about the effects on human life and on the environment. There are two common means for control. The first is reducing noise at its source, and the second is changing the sound path by distance or by shielding. The second approach is being used more often today as people become more aware of the danger of noise. New building codes require better sound insulation in homes and apart ments. More and more towns are passing zoning ordinances that try to segregate noisy fac tories or airports from residential areas. Sound-absorbent materials and construction de signed to block sound paths are slowly coming into use in offices and homes. New highways are being built to redirect traffic noise up and away from nearby areas. Aircraft are increas ingly being required to use reduced power flights around airports. There are many examples of available noise control methods that are not being used. More flexible building codes would permit the use of quieter kinds of plumbing pipes. Sound-absorbing materials can reduce the noise of motors and engines. Power genera tors can be quieted with baffles, exhaust silencers, and sound absorbers. Truck tires can be made with quieter treads. In many cases, the cost of building quieter machines is the same or only slightly higher than that of the current noisy ones. Even though the new equipment may cost more initially, it can prove more profitable in the long run. The new jumbo jets, for example, are quieter than the older ones, yet they are more powerful and carry twice as many passengers. All of these methods are only partial measures as noisy levels continue to rise. Most specialists in the field agree that much of the solution must come from eliminating some of the noise at its source, therefore saving through prevention the large costs of hearing loss.

单选题4 In most American cities, the rent for a one-bedroom apartment was $ 250 or more per month in recent years. In some smaller cities such as Louisville, Kentucky or Jacksonville, Florida the rent was less, but in larger cities it was more. For example, if you lived in Los Angeles, you had to pay $ 400 or more to rent a one-bedroom apartment, and the same apartment rented for $ 625 and up in Chicago. The most expensive rents in the U. S. were in New York City, where you had to pay at least $ 700 a month to rent a one-bedroom apartment in most parts of the city. Renters and city planners are worried about the high cost of renting apartments. Many cities now have rent-control laws to keep the cost of renting low. These laws help low income families who cannot pay high rents. Rent controls in the United States began in 1943 when the government imposed rent controls on all American cities to help workers and the families of soldiers during World War 1][. After the war, only one city—New York—continued these World War [[ controls. Recently, more and more cities have returned to rent controls. At the beginning of the 1980s, nearly one fifth of the people in the United States lived in cities with rent-control laws. Many cities have rent-control laws, but why are rents so high? Builders and landlords blame rent controls for the high rents. Rents are high because there are not enough apart ments to rent, and they blame rent controls for the shortage of apartments. Builders want more money to build more apartment buildings, and landlords want more money to repair their old apartment buildings. But they cannot increase rents to get this money because of the rent-control laws. As a result, landlords are not repairing their old apartments, and builders are not building new apartment buildings to replace the old apartment build ings. Builders are building apartments for high-income families, not low-income families, so low-income families must live in old apartments that are in disrepair. Builders and land lords claim that rent-control laws really hurt low-income families. Many renters disagree with them. They say that rent control is not the problem. Even without rent controls, builders and landlords will continue to ignore low-income housing because they can make more money from high-income housing. The only answer, they claim, is more rent controls and government help for low-income housing.

单选题It is said that in England death is pressing, in Canada inevitable and in California optional. Small wonder. Americans" life expectancy has nearly doubled over the past century. Failing hips can be replaced, clinical depression controlled, cataracts removed in a 30-minute surgical procedure. Such advances offer the aging population a quality of life that was unimaginable when I entered medicine 50 years ago. But not even a great health-care system can cure death—and our failure to confront that reality now threatens this greatness of ours. Death is normal; we are genetically programmed to disintegrate and perish, even under ideal conditions. We all understand that at some level, yet as medical consumers we treat death as a problem to be solved. Shielded by third-party payers from the cost of our care, we demand everything that can possibly be done for us, even if it"s useless. The most obvious example is late-stage cancer care. Physicians— frustrated by their inability to cure the disease and fearing loss of hope in the patient—too often offer aggressive treatment far beyond what is scientifically justified. In 1950, the U.S. spent $0.7 billion on health care. In 2002, the cost will be $1,540 billion. Anyone can see this trend is unsustainable. Yet few seem willing to try to reverse it. Some scholars conclude that a government with finite resources should simply stop paying for medical care that sustains life beyond a certain age—say 83 or so. Former Colorado governor Richard Lamm has been quoted as saying that the old and infirm "have a duty to die and get out of the way", so that younger, healthier people can realize their potential. I would not go that far. Energetic people now routinely work through their 60s and beyond, and remain dazzlingly productive. At 78, Viacom chairman Sumner Redstone jokingly claims to be 53. Supreme Court Justice Sandra Day O"Connor is in her 70s, and former surgeon general C. Everett Koop chairs an Internet start-up in his 80s. These leaders are living proof that prevention works and that we can manage the health problems that come naturally with age. As a mere 68-year-old, I wish to age as productively as they have. Yet there are limits to what a society can spend in this pursuit. As a physician, I know the most costly and dramatic measures may be ineffective and painful. I also know that people in Japan and Sweden, countries that spend far less on medical care, have achieved longer, healthier lives than we have. As a nation, we may be overfunding the quest for unlikely cures while underfunding research on humbler therapies that could improve people"s lives.
