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 call happen after the operation. He warned，irregular lumps and loose skin can reset 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Sport is not only physically challenging, but it can also be mentally challenging. Criticism from coaches, parents, and other teammates, as well as pressure to win can create an excessive amount of anxiety or stress for young athletes (运动员). Stress can be physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable. The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches criticisms to heart and find a flaw (缺陷) in themselves. Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today's youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find fault with youngsters' performances. Positive reinforcement should be provided regardless of the outcome. Research indicates that positive reinforcement motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.

单选题According to the most recent research on parenting, caretakers tend to use three strategies for disciplining children. Power includes the use of physical punishment such as spanking or the threat of physical punishment, but parents can also demonstrate power by taking away a privilege such as using the ear, attending a sporting event, or in the case of a very young child, playing with a favorite toy. In spite of the fact that power strategies, especially severe physical punishment, can cause children to fear or even hate parents, it"s surprising that power remains the strategy used most often in disciplining children. It"s also worth noting that children who are harshly disciplined in this way tend to be hostile, defiant, and aggressive socially. Second in popularity after power is the withholding of affection. This can take the form of refusal to communicate with a child, threatening to abandon or reject the child, or otherwise treating children as though they were unworthy of love. Interesting enough, children disciplined in this way appear on the surface to be very self-disciplined, even model children who are seldom in trouble, but underneath, these same children are generally very nervous, insecure and dependent others to approve of and guide their evaluation of behavior. Finally, management techniques are employed for discipline. These begin with a set of rules that are clearly expressed at an age-appropriate level. To enforce the rules, parents use a combination of praise and approval with explanation and reasoning, always referring back to the rules. But regardless of the strategy, the behavior that has precipitated punishment should be clearly understood, and the consequences should be consistent. Key to any kind of discipline is a pattern of consistency so that children understand the relationship between the rules, their behavior, and the consequences.

The first comprehensive study on the nation's oral health, released recently by the Office of the U. S. Surgeon General, calls dental and oral diseases a "silent epidemic (流行病)", even in children. The report states that more than 51 million school hours are lost each year to dental-related illness. In fact, a recent study pointed to dental care as the most common unmet health need among American children. To help counter this, the American Academy of Periodontology (牙周病学) (AAP) is launching an effort to educate children and parents about the prevention of dental diseases in children. "This is important because oral problems can impact self-esteem for children and lead to problems of eating, speaking and attending to learning," said Michael McGuire, president of the AAP. Common dental problems seen in children are cavities (龋洞) and gingivitis (龈炎),which are found in the majority of U. S. children. "When these problems are not caught early and treated, they can develop into more severe problems and cause unnecessary suffering," said McGuire. "However, much of the time, oral problems are avoidable problems." In the Rio Grande Valley in Texas, a group of more than 120 dentists (牙医) volunteers to deliver dental care to thousands of low-income children each year with its Mobile Dental Unit that travels from school to school. "According to the, Surgeon General's Report, about 37 percent of children have not had a dental visit before starting school," said McGuire. When children don't see dentists, they miss the opportunity to have problems caught early before they develop into larger, more expensive problems to treat, and parents miss the opportunity to learn how to promote good oral habits in their children."

单选题Davies is an official of the Saskatchewan Medical Society, so it's not surprising that he would want to extol Canadian medicine.

Almost all Canadians are proud of the fact thatA. Canada's health - care system covers every one of its citizens.B. many people go bankrupt each year due to medial bills.C. many people are not included in the health - care system.D. people have to wait for a long time for medical treatment.

单选题{{B}}第三篇{{/B}} Many science reports discuss medical studies that test the effect of a new drug. Usually, a large number of people is divided into two groups. Each group takes a different substance. But no one knows which group is getting which substance. One group takes the medicine being tested. Another group takes what we call an inactive substance. Medical researchers call this substance a "placebo." The word "placebo" is Latin for "I shall please." Placebo pills(宽心丸)usually are made of sugar. Using placebos to test drugs sometimes has a surprising result. Researchers say people taking the placebo often report improvements in their health. This is known as "the placebo effect"--pain that is eased or stopped by an inactive substance. In such testing, the drug must perform better than the placebo to prove that it is effective. Doctors have reported that the placebo effect can be used in treatment. For example, a doctor tells a patient that a new drug will stop the pain in his leg. The pill is only sugar. But the patient does not know that. He takes the pill and says his pain is gone. Scientists are beginning to discover some physical reasons for this reaction in some people. They are learning that much of what people believe to be true comes from what the brain expects is going to happen. If the brain believes a drug will ease pain, the brain may begin physical changes in the body that can cause the expected effect. A recent examination of studies on drugs for depression found that placebos eased the depression about as well as the active drugs. Other studies have explored the power of placebos. A study in Japan involved thirteenpeople who reacted to the poison ivy (常青藤)plant. Poison-ivy causes red itchy sores(伤痕)on some people who touch it. Each person was rubbed on one arm with a harmless leaf, but was told it was poison ivy. Each person was then touched on the other arm with poison ivy, but was told it was a harmless leaf. All thirteen people developed a reaction on the arm where the harmless leaf touched their skin. Only two reacted to the poison ivy leaves. Doctors and scientists worry that the use of placebos may not always be harmless. They say people can become victims of false doctors and others who use placebos to claim they can cure disease.

单选题In 2005 scientists in Spain reported that the more pesticides children were exposed to as fetuses (胚胎), the greater their risk of being overweight as toddlers. And last January scientists in Belgium found that children exposed to higher levels of PCBs and DDE ( the breakdown product of the pesticide DDT) before birth were fatter than those exposed to lower levels. Neither study proves causation, but they "support the findings in experimental animals," says Newbold. They "show a link between exposure to environmental chemicals...and the development of obesity. " In the paragraph the writer intends to convey to the reader thatA. there might be a link between exposure to environmental chemicals and the development of obesity.B. there is a cause - effect relation between exposure to environmental chemicals and obesity.C. children who are exposed to pesticides are likely to develop obesity in their adulthood.D. scientists have done experiments to see the link between environmental chemicals and obesity for years.
