单选题Dangerous Sunshine to Children Two Unite Nations agencies warned on Tuesday that children are most at risk of developing skin cancers as a result of the long-term decline in the earth's protective ozone layer. The agencies, the World Health Organization (WHO) and the UN Environmental Programme (UNEP), issued the warning as they launched a global programme aimed at alerting schools to the dangers of exposure to the sun. "As ozone depletion becomes more marked, and as people around the world engage more in sun-seeking behaviour, the risk of health complications from over-exposure to ultra-violet radiation is becoming a substantial public health concern, " said WHO Director-general Lee Jong-wook. By reducing the time children and adolescents are exposed to direct sunlight, he said: "We can substantially reduce the risk of contracting skin cancers, cataracts and other conditions which might only appear much later in life. " In its 2002 World Health Report, the WHO said around the world an average of 66,000 people died every year from melanoma or other types of skin cancer. Independent scientific research shows that every year there are between two to three million new cases of non-malignant melanoma and around 130,000 malignant — and normally fatal — new full-blown skin cancer cases. Although most known skin cancers seemed to occur in the industrialized world, WHO radiation and environmental health specialist Mike Repacholi told a news conference, there were many cases believed to be unreported in poorer countries. Although people with darker skins were less susceptible to skin cancers, they were just as likely to contract eye cataracts as fairer-skinned populations, and people living close to the equator were even more likely to develop them. As for the protection method, the WHO said that under the school plan, dubbed the Intersun Project, the two agencies will distribute packages showing teachers how to develop their own sun education programmes, the WHO said. In a joint statement from the two agencies which also marked the International Day for the Preservation of the Ozone Layer, UNEP Executive Director Klaus Toepfer said latest studies showed the protective shield was on the road to recovery. This was the result of international agreements over the past two decades to phase out use of various chemicals — like those used in some pesticides, refrigerators and aerosols. "But we must remain vigilant and more needs to be done before we can say that the problem is solved for good. " said Toepfer. This included stopping illegal trade in banned chemicals and enforcing the agreements in developing countries. "Only then can we say that the sky above our heads will be safe for our children and their children to come. " the former German environment minister said.

单选题Stomach Ulcer Stomach ulcers are the cause of severe pain for many people. Doctors have been able to help lessen the pain of ulcers. They could not cure them. Now doctors have discovered a cause of ulcers. This means they may have found a way to cure people who suffer from the stomach pain. Studies show that ten percent of the population will develop an ulcer at some time in their life. So a possible cure is good news for many people. Ulcers are wounds in the stomach that are similar to small cuts or tears. These wounds can harm the tissue in the stomach, the pipe that carries the food to the stomach or parts of the small intestines. Fluids in the stomach then increase the pain of an ulcer. How does a person know he or she has an ulcer? Doctors say most people with ulcers feel a burning pain in their chest or stomach. This pain often is called heartburn. It usually happens before eating or during the night. It causes some people to lose their desire to eat, or they are unable to keep food in their stomachs. Doctors believed that ulcers were caused by unusually strong stomach fluids, which damaged stomach tissue. Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H Pilorie. H Pilorie bacteria are what make stomach produce extra stomach fluid. Doctors found that they can kill the bacteria with medicines called antibiotics. Health experts say the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs. They also believe curing ulcers will reduce the number of people who develop stomach cancer. The number of people with stomach cancer is very high in Japan, Southeast Asia and parts of Africa. Doctors say a person is more likely to get an ulcer if someone in his or her family has had one. In fact a person with the family history of ulcers is three times more likely to get one than other people. There are ways people can protect themselves from developing an ulcer. Doctors say it is more important to reduce the amount of strong fluids in the stomach. To do this, doctors say, people should not smoke cigarettes or drink alcohol. And they say people should reduce tension in their lives.

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 that 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 indicated 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Step Back in Time Do you know that we live a lot longer now than the people who were born before us? One hundred years ago the average woman lived to be 45. But now, she can live until at least 80. One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for U. S. and what we have to eat to make sure our bodies get all the healthy things they need. We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily. But in order that we don"t slip back into bad habits, let"s have a look at what life was like 100 years ago. Families had between 15 and 20 children, although many babies didn"t live long. Children suffered from lots of diseases, especially rickets (佝偻病) and scurvy (坏血病), which are both caused by bad diets. This is because many families were very poor and not able to feed their children well. Really poor families who lived in crowded cities like London and Manchester often slept standing up, bending over a piece of string, because there was no room for them to lie down. People didn"t have fridges until the 1920s. They kept fresh food cold by storing it on windowsills(窗台板), blocks of ice, or even burying it in the garden. Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago, you might well be selling matchsticks(火柴杆)(a job done by many children)or working with your dad by now.

单选题 阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 Attempts to understand the relationship between social behavior and health have their origin in history. Dubos(1969) suggested that primitive humans were closer to the animals in that they, too, relied upon their instincts to stay healthy. Yet some primitive humans recognized a cause and effect relationship between doing certain thing and alleviating (减轻)symptoms of a disease or improving the condition of a wound. Since there was so much that primitive humans did not understand about the functioning of the body, magic became an integral component of the beliefs about the causes arid cutes of health disorders. So it is not surprising that early humans thought that illness was caused by evil spirits. Primitive medicines made from vegetables or animals were invariably used in combination with some form of ritual to expel harmful spirit from a diseased body. One of the earliest attempts in the western world to formulate(系统地阐述)principles of health care based upon rejection of supernatural phenomena is found in the work of the Greek physician Hippocrates. Little is known of Hippocrates who lived around 400 B. C., not even whether he actually authored the collection of books that bears his name. Nevertheless, the writings, attributed to him have provided a number of principles underlying modern practice. One of his most famous contributions, the Hippocratic Oath, is the foundation of contemporary medical ethics(道德). Among other things, it requires the physician to swear that he or she will help the sick, keep oneself from intentional wrong-doing or harm, and keep secret all matters to keep the doctor patient relation-ship. Hippocrates also argued that medical knowledge should be derived from an understanding of the natural sciences and the logic of cause and effect relation-ships. In this classic thesis, On Airs, Waters, and Places, Hippocrates pointed out that human wellbeing is influenced by the totality of environmental factors: living habits or lifestyle, climate, geography of the land, and the quality of air, and food. Interesting enough, concerns about our health and the quality of air, water, and places are still very much written in the twentieth century.

单选题{{B}}第三篇{{/B}} There seem to be two main reasons that women cry more often. One is biological. Up to age 12, boys and girls cry equally often. From then until age 18, the level of the hormone prolactin(催乳激素) rises in young women, until their blood contains 60 per-cent more than men' s. And prolactin affects the production of tears. On the sociological side, men in particular are conditioned out of crying. From the age of 12 or 13, boys are told that crying shows a loss of control, that it is a sign of weakness. If men step outside the norm and show their feelings in the workplace, they run the risk of getting labels attached that are not complimentary. Researches on conversations show that women are more likely to talk about feelings, men about activities. This is a reflection of our socialization. Also, men are more likely to express their opinions. It gives rise to women feeling enormous frustration about getting their views across. When women are crying at work, it's often out of sheer frustration, about not being able to get their needs identified, known, put across, and getting a response to them…There is a sense of "I'm not being taken seriously." The trouble is, if a woman cries in this situation, men are likely to say, "She's far too emotional." There are, though, a couple of arenas(活动场所) in which it seems to be acceptable for men to be emotional: sports and especially more recently, politics. An essay in Times magazine once reported on timely tears from former Presidents George Bush and Richard Nixon. The Times essay says 1988 presidential candidate Patricia Schroeder' s tears led some to describe her as "just another weak woman, temperamentally unfitted for the presidency". It concludes: "Men may weep, but women must prove them- selves made of sterner stuff."
