单选题Restaurants And Health "Clean your plate!" and "Be a member of the clean-plate club!" Just about every kid in the U.S. has heard this from a parent or grandparent. Often, it's accompanied by an appeal: "Just think about those starving orphans (孤儿) in Africa!" Sure, we should be grateful for every bite of food. Unfortunately, many people in the U.S. take a few too many bites. Instead of saying "clean the plate", perhaps we should save some food for tomorrow. According to news reports, U.S. restaurants are partly to blame for the growing bellies (肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They serve large portions to stand apart from competitors and to give the customers value. They prefer to have customers complain about too much food rather than too little. Barbara Rolls, a nutrition professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline began to expand. Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. A restaurant industry trade magazine reported last month that 57 percent of more than 4,000 people surveyed believed that restaurants serve portions are too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can't afford fine dining still prefer large portions. 70 percent of those earning at least $150,000 per year prefer smaller portions. But only 45 percent of those earning less than $25,000 want smaller. It's not that working class Americans don't want to eat healthy. It's just that after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck to paycheck, happy to save a little money for next year's Christmas presents.

单选题 Disease, Diagnosis, Treatment and Prevention Disease may be defined as the abnormal state in which part or all of the body is not properly adjusted or is not capable of carrying on all its required functions. There are marked variations in the extent of the disease and in its effect on the person. In order to treat a disease, the doctor obviously must first determine the nature of the illness—that is, make a diagnosis. A diagnosis is the conclusion drawn from a number of facts put together. The doctor must know the symptoms, which are the changes in body function felt by the patient; and the signs (also called objective symptoms) which the doctor himself can observe. Sometimes a characteristic group of signs (or symptoms) accompanied a given disease. Such a group is called a syndrome. Frequently certain laboratory tests are performed and the results evaluated by the physician in making his diagnosis. Although nurses do not diagnose, they play an extremely valuable role in this process by observing closely for signs, encouraging the patient to talk about himself and his symptoms, and then reporting this information to the doctor. Once the patient's disorder is known, the doctor prescribes a course of treatment, also referred to as therapy. Many measures in this course of treatment are carried out by the nurse under the physician's orders. In recent years physicians, nurses and other health workers have taken on increasing responsibilities in prevention. Throughout most of medical history, the physician's aim has been to cure a patient of an existing disease. However, the modern concept of prevention seeks to stop disease before it actually happens—to keep people well through the promotion of health. A vast number of organizations exist for this purpose, ranging from the World Health Organization (WHO) on an international level down to local private and community health programs. A rapidly growing responsibility of the nursing profession is educating individual patients toward the maintenance of total health—physical and mental.

单选题{{B}}第一篇{{/B}} I had been working in the trauma unit at a local hospital for about a year. You get used to families thinking that a "coma" patient is moving their hand or doing something that they were asked to do. "Following commands" is what we call it. Often it's "wishful thinking" on the families' part. Nurses can easily become callous to it. On this particular night during visiting hours, my patient's wife came in. I had taken care of him for severam nights. I was very familiar with his care and what he was able to do. Actually, he didn't do anything. He barely moved at all, even when something would obviously hurt him, such as suctioning. His wife was very short, about 5 feet tall. She had to stand on a stool to lean over him, so that she could see his face and talk to him. She climbed up on the stool. I spoke to her for a few minutes, and then stepped out to tend to my other patient. A few minutes later, she came running out of the room. In an excited voice, she said, "Donna, he's moving his hand!" I immediately thought that it was probably her imagination, and that he had not actually done it on purpose. He had been there about a month at the time and had never made any movements on purpose. I asked her what had happened and she said, "I asked him to squeeze my hand and he did !" This led me to another train of questioning. "But, did he let go when you asked him to?" She said yes, that he had done exactly what she asked. I went into the room with her, not really believing that I would see anything different than I had always seen. But I decided that it would be better to pacify her than to make her think I didn't believe her or that she was somehow mistaken. She asked him to squeeze her hand, which he did. I said, "Well, ask him to let go." He continued to squeeze for a moment, so that when he finally did let go, I really still didn't believe that he had done it on Purpose. So, I said, "Ask him to hold up one finger." He did as asked. Well, hmm, this was starting to get my attention. I looked at him, his face still somewhat swollen and his eyes still closed. "Stick out your tongue!" I said. He did it. I almost fell on the floor. It was the first time I had ever seen anyone "wake up. "

单选题 Road Trip Vacations It's summer. In the United States, it's the season of swimming pools, barbeques, camping and road trips. Road trip vacations where the car journey is part of the fun are especially popular with college students, who like to explore the country on wheels. These budget trips are ideal for students who often have plenty of free time but little money. "Ever since I went to college, I've been traveling around a lot, exploring the country," said Austin Hawkins, a 19-year-old college student from New York. This summer, Hawkins and his friends have spent weekends traveling in New England. "The best part about car trips", said Hawkins, "is that you can be spontaneous. On a road trip, if you get interested in things you see along the way you can stop and explore." Matt Roberts, a 20-year-old student from Ohio who drove to Montreal, Canada, agrees. "With road trips you don't have to plan in advance, you can just get into a car and drive." Even with high gas prices, driving with friends is cheaper than flying. Roberts paid about 40 dollars for gas, but a round trip plane ticket would have cost nearly 400 dollars. Driving trips first became popular in the 1920s. Newly paved roads and improved cars made it possible to travel longer distances. Motels started appearing outside cities. By the 1950s, car ownership became the norm. Construction of the U. S. interstate highway system began in 1956 and motel and restaurant chains popped up everywhere making long distance trips easier. Today, the U.S. has the highest car ownership rate in the world. Only 8 percent of American homes have no car, according to the most recent U. S. census. Though many college students don't own a car, most have access to one. On many of Hawkins' trips, they used a borrowed van. Hawkins' most memorable road trip took place over spring break. He and two friends drove from New York to New Orleans to volunteer, helping rebuild the city after Hurricane Katrina hit it last July. They crossed the country in two days and slept in their car in church parking lots. Roberts' road trip to Canada last winter was even more eventful. Upon arriving in Montreal, they were lost in a blizzard and shivering in the —25~cold. To find their hotel, they turned on a laptop and drove around in circles until they found a spot with wireless Internet coverage. "I know we should have planned better, but we're young. Now, when I see those guys I always say: 'Remember when we were lost in the snow storm!' I'll never forget that."

单选题{{B}}第三篇{{/B}} The air is polluted. The earth is poisoned. Water is unsafe to drink and garbage is burying the civilization that produced it. Our environment is being polluted faster than nature and man's efforts can prevent it, Time is bringing us more people, and more people will bring us more industry. More people and more industry will bring us more motorcars, larger cities, and the growing use of man-made materials. This is happening not only in advanced societies but also among the developing nations as they become industrialized. Now many scientists are worrying about the possibility of world pollution. Some experts declare that the balance of nature is being so upset that the very survival of human beings in danger. What can solve this problem? The fact is that pollution is caused by man--by his greed and his modern way of life. We make "increasing industrialization(工业化)" our chief aim. For its sake we are willing to sacrifice everything: clean air, pure water, good food, our health, and the future of our children. There is a constant flow of people from the country into the cities, eager for the benefits of modern society. But as our technological achievements have grown in the last twenty years, so in that time pollution has became a serious problem. Isn't it the time we should stop and ask ourselves where we are going--and why? It reminds one of the stories about the airline pilot who told his passengers over the loud speakers: "I've some good news and some bad news. The good new is that we're making rapid progress at 530 miles per hour. The bad news is that we're lost and don't know where we're going." The sad fact is that this becomes a true story when applied to our modern society.
