More and more scientific experiments prove that physical exercise can reduce the dangers of some illnesses in middle-aged persons.Exercise strengthens the heart muscle,reduces blood pressure and help to prevent muscles from changing into fat.Physical exercise is just as important for children. Exercise and food affect growing speed in young lab animals.Baby mice start running as soon as they are big enough to use an exercise wheel in their cage.If they get extra food and run a lot,they will grow as much as 1.5 times bigger than normal. The same differences in growing speed might be found between active and inactive children.Physical exercise helps active children grow faster than inactive children.One experiment shows that the brains of the mice that had enough exercise weighed about 3%more than those of the mice that did not exercise The mice that exercised are much quicker to learn doing new exercise than the mice that did not exercise. The results of the experiments suppose the theory that exercise can help babies learn to talk and walk sooner than expected. The good effects of physical exercise are not limited to children and middle-aged people.Exercise continues to be an important part of our lives after we grow old.For example,people over 50 years old begin to lose calcium from their bones,which get weaker and can break easily.Physical exercise,however,helps to strengthen the bones and to prevent them from losing calcium.Of course,old people can take medicines to prevent themselves from suffering from losing calcium.But the medicines they take increase the chance of developing some kind of cancer .So physical exercise is a much safer treatment . From the passage we know that_. A) mice need to eat more and exercise more B) children need more exercise than other people C) old people like to take medicine to treat their illnesses D) middle-aged people are easy to get fat

Q: 55% of deaths caused by road accidents occur in the first few minutes after a crash. Up to 85% of these deaths could be prevented if first aid were given. The first person on the scene of a road accident will almost certainly be another road user. So as a driver your knowledge of first aid could make a real difference to someone in the event of a road accident. Assess conditions *Remain calm. Judge the scene and seriousness of the collision. *Determine what has happened, how many people and vehicles are involved and the exact location. *Determine how many casualties there are, what is the severity of the injuries, whether anyone is trapped, and whether there is a danger of fire. Make safe *Make sure you stay safe and keep off the road. If you need to stop or warn approaching cars, signal to them from the pavement. Wear reflective clothing, use warning triangles, flashing lights and warning lights. Don't smoke. *If you are in a car and you come across an accident, first park safely and turn off the engine before you get out to help. Use a triangle warning danger if necessary. *Consider the safety of others. Don't move the vehicles, look out for dangers -- leaking fuel, chemicals, broken glass or dropping loads -- guide uninjured passengers to a place of safety. Call for help Dial 999 (or 112) for the emergency services. If there is no phone nearby, send two people in opposite directions to seek help. Do this as soon as you can or get someone else to do it while you deal with an injured person. You will need to tell the emergency services: *where you are *what has happened (describe the accident) *how many people are injured *whether they are breathing or bleeding. The operator will talk you through what to do while you wait for an ambulance to arrive. Apply emergency first aid *Remain calm. Reassure the victims. *Do not allow smoking or offer food or drink to casualties as this could _ urgent medical treatment. When a driver is applying first aid, which of the following is proper? A) Stand in the middle of the road to stop or warn approaching cars. B) Leave the engine working when he gets out of his car to help.

The film The Tides of Kirawira, which won two prizes at a recent television festival, was made by Mark Deeble and Victoria Stone. The couple are inprefix = st1 /Englandto visit friends and family before heading back toTanzaniafor their next film. Their work takes them to some of the world's least-known areas but they still find themselves drawn back toEngland, particularly toCornwall, where their work and personal relationship developed. "We met in London when Mark was studying biology and I was at the Royal College of Art studying photography," says Victoria. "We both learned to dive at the same pool inLondonand went on diving weekends in the country. It was a terrible place, freezing cold, where we dived in wet suits full of holes. But that is where our relationship developed." After completing their studies they took part in the management of a conservation area in the mouth of the River Fal in Cornwall. "We were shocked. Nobody seemed to understand the river's ecological importance. So we thought, why don't we make a film to show people what a special place it is? Neither of us had any experience of filming but we took part-time jobs until we had enough cash to buy an underwater camera and some film." A television company agreed to provide money for the work and the film they produced about the underwater life of the River Fal was shown on television and won a number of prizes. By then, they both knew they wanted to work with wildlife in distant places around the world. Alkan Root, a famous East African wildlife film-maker, asked them to work for him. That was seven years ago and the job took them to the Serengeti to film crocodiles. Their films, Here Be Dragons andDevil Fish, were very successful. "We love Africa but we have to come back to Englandevery year," saysVictoria. "We need to return to see our friends and family. For us, Africa is temporary andEnglandmeans permanence. It's the difference between living in a tent inTanzaniaand a house inCornwall. We are lucky... we have the best of both worlds." The purpose of filming in the River Fal was to _ . A) earn money B) educate people C) gain photographic experience D) make a television program
