Here"s a new warning from health experts: Sitting is deadly. Scientists are increasingly warning that sitting for prolonged periods-even if you also exercise regularly-could be 1 for your health. And it doesn"t matter where the sitting takes place-at the office, at school, in the car or before a computer or TV-just the overall number of hours it 2 . Research is preliminary, but several studies 3 people who spend most of their days sitting are more likely to be fat, have a heart attack or even die. In an editorial 4 this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define 5 activity to highlight the dangers of sitting. While health officials have issued guidelines 6 minimum amounts of physical activity, they haven"t suggested people try to limit how much time they spend in a seated 7 . "After four hours of sitting, the body starts to send 8 signals," Ekblom-Bak said. She explained that genes regulating the amount of glucose and fat in the 9 start to shut down. Even for people who 10 , spending long stretches of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day- 11 still spend a lot of time sitting-might get more benefit if that exercise were spread across the day, 12 in a single bout. That wasn"t 13 news for Aytekin Can, 31, who works at a London financial company, and spends most of his days sitting 14 a computer. Several evenings a week, Can also teaches jiu jitsu, a Japanese martial art 15 wrestling, and also does Thai boxing. "I"m sure there are some detrimental 16 of staying still for too long, but I hope that being 17 when I can helps," he said. "I wouldn"t want to think the sitting could be 18 dangerous." Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat 19 had a higher death risk, independently of whether or not they exercised. Figures from a US survey in 2003-2004 found Americans spend more than half their time sitting, from working at their desks to sitting in cars. Experts said more research is needed to 20 just how much sitting is dangerous, and what might be possible to offset those effects. |

Here are some suggestions. Family Meals Family meals are comforting for both parents and kids. Children like to guess what they are going to have and parents get the chance to introduce new foods to children and to find out which foods they like and which ones they don"t. Teens may turn up their noses at your plan of a family meal. It is not surprising because they"re trying to establish independence. Yet studies find that teens still want their parents" advice, so they use the mealtime as a chance to reconnect. Stocking Up on Healthy Foods Kids, especially younger ones, will eat mostly what they can get at home. That"s why it"s important to control the supply lines-the foods which you serve for meals and have on hand for snacks. You should have enough fruits, vegetables, lean meat and other good sources of protein, such as eggs and nuts, and healthy snacks, such as yogurt, peanut butter and whole-grain biscuits. Being a Good Example The best way for you to encourage healthy eating is to eat well yourself. Kids will follow the lead of the adults they see every day. By eating fruits and vegetables and avoiding fast food and sugary drinks, you"ll be sending the right message. No Conflicts over Foods Parents might find themselves shouting at children to get them to have healthy foods in front of them. This in fact can make children dislike what they are asked to eat. Get Kids Included Most kids will enjoy making the decision about what to make for dinner. Talk to them about making choices and planning a balanced meal. It can help prepare them to make good decisions on their own about the foods they want to eat. | 1.

Experts at the first Chinese Students Nutrition and Health Festival in Kunming last week singled out (挑选) several bad eating habits. ●Watching television while having meals or snacks (零食). Doing this means you don"t pay attention to your food, forget how full you are, and so overeat. It can also cause digestion (消化) diseases. One way to avoid this is only to eat in certain areas of your home. ●Replacing meals with snacks. Many students think that eating small snacks can help them diet. But it often results in overeating and health problems related to a lack of vegetables, carbohydrates (碳水化合物), proteins and vitamins. Snacking only works if it is well planned and includes healthy foods such as nuts, vegetables, fruit and yogurt (酸奶). ●Having drinks rather than water. Fizzy (有气泡的) drinks and fruit juice are usually high in calories and sugar, which can cause weight problems. Water is important in making your brain cells and every organ in your body work properly. For your body to burn fat, it needs at least eight glasses of pure water a day. Liquids like soda (苏打水) and coffee actually take water away from your body. ●Choosing meat and certain vegetables over others. Different foods provide different kinds of nutrition. If you don"t have a balanced diet, this can result in malnutrition (营养失调) and a weaker body. ●Eating throat tablets (润喉片) as if they were sweets. If you eat throat tablets when you have no throat disease, they may affect the bacteria (细菌) in your mouth and cause real throat problems. | Develop a Healthier Lifestyle

The warmth of the land heats the air above, causing it to rise and tiny drops of water to fall as rain. The rainfall can reach at least 98 inches a year. This wet, warm world with plenty of sunlight is perfect for plants to grow, so the trees grow fast with green leaves all the year round. The trees themselves also have an effect on the climate. They gather water from the soil and pass it out into the air through their leaves. The wet air then forms clouds, which hang over the treetops like smoke. These clouds protect the forest from the daytime heat and night-time cold of nearby deserts, keep temperatures fit for plant growth. Rain forests slightly farther away from the equator remain just as warm, but they have a dry season of three months or more when little rain falls. Tree leaves fall during this dry season and new leaves grow when the wet season or monsoon (雨季) begins. Thus these areas are known as the "monsoon forest". Another type of rain forest grows on tropical mountains. It is often called the "cloud forest" because clouds often hang over the trees like fog. The rain forest is the ideal place for the growth of many different trees. Most of them depend on animals to eat their fruits and spread their seeds. When the fruits are eaten, the seeds inside them go undamaged through animals, stomachs and are passed out in their droppings. The seeds lying on the forest floor then grow into new trees. | 1. The climate of the rain forests near the equator is _____. | [ ] | A. mild, wet and windy B. hot, rainy and foggy C. warm, wet and sunny D. hot, wet, cloudy | 2. We can learn from the passage that _____. | [ ] | A. tree leaves are green all the time in the monsoon forest B. there is a dry season in the cloud forest on tropical mountains C. clouds help the plants in the rain forest near the deserts to grow D. the formation of climate in the rain forest has little to do with the trees | 3. According to the passage _____ play the most important role in the spreading of seeds. | [ ] | A. animals B. droppings C. fruits D. winds | 4. This passage is most likely to be found in _____. | [ ] | A. a travel guide B. a storybook C. a technical report D. a geographical book | 阅读理解。 | Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences. Now American researchers think they are close to developing a pill, which help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far, the research has suggested that only the emotional effects of meomories may be reduced, not that the memories are erased. The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers" troubling memories after wars. They say that there are many people who suffer from terrible memories. "Some memories can ruin people"s lives. They come back to you when you don"t want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry (精神病学) at Harvard Medical School. "This could relieve( 减轻) a lot of that suffering." But those who are against the research say that changing memories is very dangerous because memories give us our identity. They also help us avoid the mistakes in the past. "All of us can think of bad events in our lives that were horrible at the time but make us who we are. I am not sure we"d want to wipe those memories out." said Rebecca Dresser, a medical ethicist. | 1. What"s the main idea of this passage? | [ ] | A. People often suffer from bad memories. B. American researchers are trying to develop a pill. C. Forget bad memories, and be happy. D. The research has caused a heated argument. | 2. The underlined word "it" in Paragraph 4 refers to "_____". | [ ] | A. the new drug B. the research into the drug C. the bad memory D. the chemical in the drug | 3. Which of the following is NOT the opinion of the opponents (反对者)? | [ ] | A. Our memories give us our identity. B. The memories help human avoid mistakes of the past. C. The drug should be used in only very serious cases. D. People may not be sure whether they want to wipe the memories out. | 阅读理解。 | There is an English saying, "Laughter is the best medicine." Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people"s health. Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial. Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programmes. The group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny programme. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain. As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients" condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter. | 1. According to the passage, which of the following statements is WRONG? | [ ] | A. Laughter is good for health. B. Laughter can make you become old quickly. C. Laughter helps to reduce pain. D. Laughter, just like physical exercise, is good for our body. | 2. The underlined word "diminishes" in the third paragraph means "_____". | [ ] | A. delays B. prevents C. increases D. reduces | 3. Why do doctors hold laughter clinics? | [ ] | A. Because they want to earn more money. B. Because they think they will help the patients recover from illnesses. C. Because they want to improve their patients" health. D. Because they want their patients to laugh more. | 4. What would be the best title for this passage? | [ ] | A. Both laughter and physical exercise are good for health. B. Laughter clinics can help patients improve their condition. C. Laughter can reduce the effect of pain. D. Laughter is the best medicine. |
