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.

| The Diet Zone: A Dangerous Place Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word "diet" everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically. Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption (消耗)of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word "diet" in food labels(标签). On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don"t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance (抵 抗)and struggle. The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients (营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous. Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them. | |||
| 1. From Paragraph 1, we learn that _____. | |||
| A. diet products fail to bring out people"s potential B. people have difficulty in choosing diet products C. diet products are misleading people D. people are fed up with diet products | |||

| A. try out a variety of diet foods B. hesitate before they enjoy diet foods C. pay attention to their own eating habits D. watch their weight rather than their diet | |||
| 3. In Paragraph 3, "gain comes without pain" probably means _____. | |||
| A. losing weight is effortless B. it costs a lot to lose weight C. diet products bring no pain D. diet products are free from calories | |||
| 4. Diet products indirectly harm people physically because such products _____. | |||
| A. are over-consumed B. lack basic nutrients C. are short of chemicals D. provide too much energy | |||

| The black robin is one of the world"s rarest birds. It is a small, wild bird, and it lives only on the island of Little Mangere, off the coast of New Zealand. In 1967 there were about fifty black robins; in 1977 there were fewer than ten. These are the only black robins left in the world. The island has many other birds, of different kinds, large and small; these seem to multiply very happily. Energetic steps are being taken to preserve the black robin. Detailed studies are going on, and a public appeal for money has been made. The idea is to buy another island nearby as a special home, a "reserve", for threatened wild life, including black robins. The organizers say that Little Mangere should then be supplied with the robin"s food-it eats only one kind of seed. Thousands of the required plants are at present being cultivated in New Zealand. The public appeal is aimed at the conscience of mankind, so that the wild black robin will not die out and disappear form the earth in our time at least. Is all this concern a waste of human effort? Is it any business of ours whether the black robin survives or dies out? Are we losing our sense of what is reasonable and what is unreasonable? In the earth"s long, long past, hundreds of kinds of creatures have evolved, risen to a degree of success-and died out. In the long, long future, there will be many new and different forms of life. Those creatures that adapt themselves successfully to what the earth offers will survive for a long time. Those that fail to meet the challenges will disappear early. This is nature"s proven method of operation. The rule of selection-"the survival of the fittest"-is the one by which human beings have themselves arrived on the scene. We, being one of the most adaptable creatures the earth has yet produced, may last longer than most. You may take it as another rule that when, at last, human beings show signs of dying out, no other creature will extend a paw to put off our departure. On the contrary, we will be hurried out. For nature, tough fair, is a hard-hearted mistress. She has no favorites. Life seems to have grown too tough for black robins. I leave you to judge whether we should try to do something about it. | |||
| 1．The black robin is dying out mainly because . | |||
| A. people have been very careless about its survival B. the appeal for money has come at the wrong time C. the other birds on the island have destroyed it D. its only food supply is far from enough on Little Mangere | |||
| 2．In Paragraph 3, the writer puts forward three questions to . | |||
| A. make a comparison B. make an argument C. present his own idea D. introduce a topic | |||
| 3. The writer"s attitude towards the protection of the black robins is . | |||
| A. passive B. active C. unconcerned D. optimistic | |||

| Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements (补品), though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease. In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines. Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight. Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products. In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need. | |||

| A. How many vitamins a person"s body needs. B. How many vitamins some foods contain. C. The benefits that vitamins bring to our health. D. What people should do to stay healthy. | |||
| 2. Vitamin supplements are popular with people because ________. | |||
| A. people mistakenly think that they are good for their health B. they contain more vitamins than the foods people eat C. food does not provide enough vitamins people need D. people fear that a lack of vitamins will lead to disease | |||
| 3. From the passage, we can learn that medical experts advise people _________. | |||
| A. never to take any vitamin supplements B. to depend only on food for their vitamins C. not to take any vitamins together with medicines D. to consult doctors before taking vitamin supplements | |||
