But in the study of five wealthy countries, published in the journal Health Affairs, researchers found no single nation had clearly the worst or best health care system. Gerard Anderson at Johns Hopkins University's school of public health and colleagues came up with a list of 21 health fields they could evenly compare across the five countries — Australia, Canada, Britain, New Zealand and the United States. "None of the five countries is consistently the best or the worst on all 21 indicators," Anderson said during a telephone briefing for reporters. "If you are looking for the place to get the best care, there isn't a single place. Every country has at least one indicator where it scores the best of the five countries and each country has at least one indicator where it scores the worst of the five countries." But, he said, the United States is not getting value for money. "The United States should be particularly concerned about these results, given that we spend twice as much on health care as any other country. So spending more doesn't necessarily result in better outcomes." Anderson's group of international health experts sponsored by the Commonwealth Fund spent five years working on the study, getting the latest possible data from the five countries on areas such as breast cancer and leukemia survival, suicide rates, death rates from asthma, vaccination rates and cancer screening.

单选题Dorm Food More Comfy Once upon a time, eating in an American college dorm meant soup in a hotpot or getting pizza delivered. The most interesting thing about the campus dining hall was often the salad bar. No more. These days, US college students have refined tastes and a growing interest in preparing their own food. Mini-refrigerators and microwaves in dorm rooms are as essential as laptops. "The cooking awareness of college students is increasing," said Tom Post, president of campus dining for Sodexo, a major food service company. "Students today grew up watching celebrity chefs on TV, eating organic food and valuing good nutrition." In response, cafeteria menus have changed. Sodexo's top campus foods for 2009 include Vietnamese noodle soup, goat cheese salad, and Mexican chicken. But colleges are also catering to student demands for more flexible and personalized dining options. Chart wells, the company that prepares food for dining halls at Ohio Wesleyan University in the state of Ohio, offers microwaveable meals that students can take away, as well as a program where students can have food individually prepared. Or they can even do their own cooking. This fall, Sarah Lawrence College in New York will offer students on its meal plan a chance to pick up groceries in the cafeteria as an alternative to a cooked meal. "Students want things that are easy to make, things that don't take long and will still taste good," said Rachel Holcomb, a University of Massachusetts-Amherst student who updated recipes for the new edition of The Healthy College Cookbook. Angelo Berti, a chef at the College of the Holy Cross in Worcester, Massachusetts, teaches cooking in dorm kitchens. But Berti says he's not just teaching recipes. He's encouraging students to use dining together as a way to socialize and as a means of self-expression; "The meal is your canvas," Berti said. "You paint .what you want." That's why at the College of William & Mary in Virginia, students produce a cooking show filmed in a dorm called "Everyday Gourmet". One episode was "Date Night Cooking: A 3-Course meal for under $20," featuring grilled chicken stuffed with goat cheese and basil.

单选题It has been argued that an infant under three who is cared for outside the home may suffer because of the separation from his parents. The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion. Firstly anthropologists point out that the secluded love affair between children and parents found in modern societies does not usually exist in traditional societies. For example, we saw earlier that among the Ngoni the father and mother of a child did not rear their infant alone--far from it. But traditional societies are so different from modern societies that comparisons based on just one factor are hard to interpret. Secondly, common sense tells us that day care would not be so widespread today if parents, caretakers or pediatricians found that children had problems with it. But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial. Thirdly, in the last decade, there have been a number of careful American studies of children in day care, and they have uniformly reported that day care had a neutral of slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.

单选题Cosmetic Surgery Surgery that can improve the way a person looks is becoming more and more popular in the United States. This kind of surgery is called cosmetic surgery, and both men and women are turning to this treatment as a way of keeping their appearance young as well as keeping competitive (有竞争力的) in their jobs. Men especially are beginning to turn to face-lifts (面部拉皮手术), liposuction( taking fat out of the body), and implants (putting artificial parts into their bodies) to help them look younger. As companies downsize (缩编) and move younger employees into higher positions, older employees in their late forties and early fifties feel the need to look and act younger in order to stay competitive. These operations are not without dangers, however. One young woman had an eye operation to get rid of the bags under her eyes; she described her experience as terrible. She said, "When he started cutting, I was fully awake. Even though he"d given me an injection near my eyes, I saw everything. " She went on to explain, "I knew I had to keep still because of what he was doing. He was scraping(刮) away fat underneath my eyes. It took about ten minutes. After he finished, I felt I couldn"t walk. I was so faint. " Her troubles did not end after the operation for two weeks. Her eyes were swollen(肿胀的) and almost completely closed, and even dark glasses could not hide the side effects of the operation. Liposuction, taking fat out of the body, is probably the most popular cosmetic operation in the United States. It seems simple enough. First, a small cut is made over the place where the patient wants the fat removed. Next, a small pipe is put into the cut. A machine like a vacuum cleaner is then used to suck the fat out of the body. However, as one doctor explained, some problems can happen after the operation. He warned, "Irregular lumps and loose skin can result from this operation. If it is not evenly done, liposuction can produce a very lumpy result." Patients often must have more liposuction to correct the problem.

单选题Baseball There are people in Italy who can't stand soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn or even frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it's a game better suited to the 19th century, slow, quiet and gentlemanly. These are the same people you may be one of them who love football because there's the sport that glorifies "the hit". By contrast, baseball seems abstract, cool, silent and still. On TV the game is fractured into a dozen perspectives, replays and close ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space and time for involvement. The TV won't do it for you. Take, for example, the third baseman. You sit behind the third base dugout and you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms or bring the glove to a point in front of him, takes a step right or left, backward or forward, perhaps he glances across the field to check his first baseman's position. Suppose the pitch is a ball. "Nothing happened," you say. "I could have had my eyes closed". The skeptic and the innocent must play the game. And this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood if football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking of notes, chores and responses.

单选题The Best Way to Reduce Your Weight You hear this: "No wonder you are fat. All you ever do is eat." You feel sad: "I skip my breakfast and supper. I run every morning and evening. What else can I do?" Basically you can do nothing. Your genes, not your life habits, determine your weight and your body constantly tries to maintain it. Albert Stunkard of the University of Pennsylvania found from experiments that, "80 percent of the children of two obese parents become obese, as compared with no more than 14 percent of the offspring of two parents of normal weight. " How can obese people become normal or even thin through dieting? Well, dieting can be effective, but the health costs are tremendous. Jules Hirsch, a research physician at Rockefeller University, did a study of eight fat people. They were given a liquid formula providing 600 calories a day. After more than 10 weeks, the subjects lost 45 kg on average. But after leaving the hospital, they all regained. The results were surprising: by metabolic measurement, fat people who lost large amounts of weight seemed like they were starving. They had psychiatric problems. They dreamed of food or breaking their diet. They were anxious and depressed; some were suicidal. They hid food in their rooms. Researchers warn that it is possible that weight reduction doesn"t result in normal weight, but in an abnormal state resembling that of starved non-obese people. Thin people, however, suffer from the opposite: They have to make a great effort to gain weight. Ethan Sims, of the University of Vermont, got prisoners to volunteer to gain weight. In four to six months, they ate as much as they could. They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended, they were back to normal weight and stayed there. This did not mean that people are completely without hope in controlling their weight. It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight. The findings also provide evidence for something scientists thought was true—each person has a comfortable weight range. The range might be as much as 9 kg. Someone might weigh 60-69kg without too much effort. But going above or below the natural weight range is difficult. The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.

S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday. Officials from the U. S. government's National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness. The study will examine hereditary(遗传的) and environmental factors such as exposure to certain chemicals that affect health. Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said. Officials said more than $ 200 million has been spent already and the study is projected .to cost $ 3.2 billion. "We anticipate that in the long term(从长远说来), what we learn from the study will result in a significant savings in the nation's health care costs. " Dr. Duane Alexander, who heads the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters. The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up(使报名从事) pregnant women whose babies will then be followed to age 21. Some of the early findings will be about factors behind pre-term birth (早产), which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study. The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.
