单选题Sleepwalking (梦游) Not all sleep is the same every night. We experience some deep, quiet sleep and some active sleep, which is when dreams happen. You might think sleepwalking would happen during active sleep, but a person isn't physically active during active sleep. Sleepwalking usually happens in the first few hours of sleep in the stage called slow-wave or deep sleep. Not all sleepwalkers actually walk. Some simply sit up or stand in bed or act like they're awake when in fact, they're asleep! Most, however, do get up and move around for a few seconds or for as long as half an hour. Sleepwalkers' eyes are open, but they don't see the same way they do when they're awake and often think they're in different rooms of the house or different places altogether'. Sleepwalkers tend to go back to bed on their own and they won't remember it in the morning. Researchers estimate that about 15% of kids sleepwalk regularly. Sleepwalking may run in families (在家族中世代相传) and sometimes occurs when a person is sick, has a fever, is not getting enough sleep, or is stressed (紧张). If sleepwalking occurs frequently, every night or so, it's a good idea for your mom or dad to take you to see your doctor. But occasional sleepwalking generally isn't something to worry about, although it may look funny or even scary (骇人的) for the people who see a sleepwalker in action. Although occasional sleepwalking isn't a big deal, it's important, of course, that the person is kept safe. Precautions (预防措施) should be taken so the person is less likely to fall down, run into something, or walk out the front door while sleepwalking.

单选题 We all know there are times that kids seem to complain {{U}}(51) {{/U}} a stomach ache to get out of chores or going to school. Don't be so sure that the pain they {{U}}(52) {{/U}} is all in their minds. We're learning more now about a condition {{U}}(53) {{/U}} "functional abdominal pain" that is experienced by millions of kids every day. Like many teenagers, Kyle Brust makes it a point to do his homework as {{U}}(54) {{/U}} as he gets home. Unlike most, Kyle often did his with a terrible stomach ache. In fact, the {{U}}(55) {{/U}} often started while he was at school, but getting help there was getting harder. "Some of my teachers wouldn't let me go, because I'd asked so many times before and they thought I was trying to get out of {{U}}(56) {{/U}}," says Kyle. Kyle's morn Marilyn says she couldn't blame the {{U}}(57) {{/U}}. After all, she'd taken him to the doctor several times herself, and even they couldn't find anything {{U}}(58) {{/U}}. "You know, you're running the tests and nothing's coming up. So, is it in his head, is he just an extremely stressful child? It's just frustrating {{U}}(59) {{/U}} we're not finding any answers," says Marilyn. It turns out Kyle was suffering from a condition known {{U}}(60) {{/U}} functional abdominal pain, that affects as many as one out of every ten kids in this country. Even {{U}} (61) {{/U}} the cause of the pain may not be obvious, there are real consequences. "It really does hurt, and these kids really do suffer," says Dr. Campo, MD at Nationwide Children's Hospital. To help {{U}}(62) {{/U}}, Campo is looking into a new approach. He's conducting clinical trials of an antidepressant that changes the way the body handles a chemical called serotonin. In a preliminary study, Dr. Campo found that in about eight out of ten {{U}}(63) {{/U}}, the drug normally used to treat emotional pain worked to ease the pain in the {{U}}(64) {{/U}}. "We think about it as being important in anxiety and depression and that's all quite true, but what's really interesting is that 95% of our body's serotonin is in our gut, " says Campo. Campo believes these kids have extremely sensitive intestines, and controlling the effects of serotonin may {{U}}(65) {{/U}}ease the pain. It seemed to work for Kyle, who is now completely pain free for the first time in years.

单选题Too Polite for Words A Japanese colleague the other day was talking about a meeting with a man whom she abruptly described using the English word "jerk". I thought she was toning down her Japanese for my benefit, so I asked her how to say "jerk" in Japanese. "There's no such word," she answered helplessly. "We have to use 'jerk'". Heaven knows it's not as if there are no jerks in Japan. But the Japanese language is just not made for sniping at people. At first, I thought maybe my Japanese teachers had been too polite to teach me the real lingo, so I watched to see what Japanese drivers would say to each other after a car accident. It turned out that they say: "I'm sorry." Gradually I came to realize that there is perhaps no language so ill suited to invective as Japanese. Linguistically, these guys are wimps. Take the vicious Japanese insult "kisama," which is deeply offensive. It means . "your honorable self. "That's right. Instead of using all kinds of dirty words, the Japanese insult each other by frowning and growling: "Your honorable self." Likewise, a nasty expression for a woman is "ama," another term not to try with the nice woman at the sushi restaurant. But literally it means "nun". Sure, sarcasm may be intended, but still most women would probably prefer to be characterized as a nun than as a female dog. Since people are least inhibited when they are shaking their fists at each other, insults offer a window into a culture. I've been interested in such terms ever since I arrived in Cairo a dozen years ago to study Arabic and discovered that my name was a curse. "Nick" sounds very much like the imperative of an extremely vulgar verb for sex. I would introduce myself in Arabic, and my new acquaintance would flee in horror. There's no such danger in Japanese. There are explicit terms for sex and for body parts, crude as well as clinical, but they are descriptive rather than insulting. There is one exception. One of the meanest things one Japanese child can say to another is: "Omaeno kaachan debeso." That means: "Your mom's belly button sticks out." This has no deep Freudian meaning; it simply means that your mother is rude and ugly.

单选题 FDA: Human, Animal Waste Threatens Produce The biggest food safety risk for fresh fruits and vegetables as they are grown, picked or processed comes from human and animal waste, the US Food and Drug Administration (FDA) said Friday. More than 9,000 Americans die each year from food-borne diseases and some scientists believe fresh produce is the biggest carrier of contamination. The FDA issued a set of draft guidelines for US and foreign growers to carefully monitor worker hygiene, water quality, manure management and transportation. These 34-page draft guidelines urged growers to give workers lessons on basic hygiene such as using soap to wash their hands, coveting wounds that could come into contact with produce, and using only clean toilets. The FDA guidelines identified "the major source of contamination" for fresh produce as human or animal feces. "We think just proper controls and proper attention to detail would make a big difference in food safety," said an FDA official. "It is our belief that these guidelines would not be very costly." But grower groups disagreed with the FDA's assessment. "Most food-borne disease outbreaks that happen further down the distribution line are due to contamination because people preparing food are not properly washing their hands," said Stacey Zawal, an official with United Fresh Fruit and Vegetable Association. "That is not necessarily true for growers and packers." Some US grower organizations have expressed concern that the agency is interfering with on-farm practices. Others object to the FDA's proposal to have growers formally document the picking, handling and transportation of produce so that health officials could quickly recall foods if necessary. Consumer groups criticized the FDA guidelines as of little use because they will not carry the force of law. But stricter regulations could evolve as researchers find new technology or methods to kill harmful bacteria or parasites, the FDA said. The FDA recommendations are due to be made final by the FDA later this year for use by US and foreign growers. The matter of encouraging foreign growers to adopt the guidelines remains somewhat tricky but FDA officials say it is vital because of the huge amount of imported produce.

单选题My mother wanted to die. but the doctors wouldn't let her. At least that's the way it seemed to me as I stood by her bed in an intensive - care unit at a hospital in Hilton Head, S.

She knew that her quality of life was increasingly tethered to an oxygen tank, that she was losing her ability to get about, and that she was slowly drowning. The doctors at her bedside were recommending various tests and procedures to keep her alive, but my mother, with a certain firmness I recognized, said no. She seemed puzzled and a bit frustrated that she had to be so insistent on her own demise (死亡). "Tethered" in the paragraph can be best replaced byA. tied.B. enclosed.C. surrounded.D. belonge

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.
