第三篇 Preserving Nature for Future Demands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe. Studies by the Council of Europe, of which 21 counties are members, have shown that 45 percent of reptile(爬行类的) species and 24 percent of butterflies are in danger of dying out. European concern for wildlife was outlined by Dr Peter Baum, an expert in the environment and natural resources division of the council, when he spoke at a conference arranged by the administrators of a British national park. The park is one of the few areas in Europe to hold the council’s diploma for nature reserves of the highest quality, and Dr. Peter Baum had come to present it to the park once again. He was afraid that public opinion was turning against national parks, and that those set up in the 1960s and 1970s could not be set up today. But Dr. Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right. "No area could be expected to survive both as a true nature reserve and as a tourist attraction," he went on. The short-sighted(眼光短浅的) view that reserves had to serve immediate human demands for outdoor recreation should be replaced by full acceptance of their importance as places to preserve nature for the future. "We forget that they are the guarantee of life systems, on which any built-up area ultimately depends, " Dr. Baum went on, "We could manage without most industrial products, but we could not manage without nature. However, our natural environment areas, which are the original parts of our countryside, have shrunk to become mere(纯粹的) islands in a spoiled and highly polluted land mass." In Dr. Baum’s opinion, the view that a nature reserve should serve as a tourist attraction is

The Royal Society for the Prevention of Accidents says that on average 15 people drown in British pools each year, but more suffer major injury after getting into difficulties. Now a French company has developed an artificial intelligence system called Poseidon that sounds the alarm when it sees someone in danger of drowning. When a swimmer sinks towards the bottom of the pool, the new system sends an alarm signal to a poolside(游泳池边) monitoring station and a lifeguard’s pager. In trials(试验)at a pool in Ancenis, near Nantes, it saved a life within just a few months, says Alistair McQuade, a spokesman for its maker, Poseidon Technologies. Poseidon keeps watch through a network of underwater and overheard video cameras. AI software analyses the images to work out swimmers trajectories(轨道). To do this reliably, it has to tell the difference between a swimmer and the shadow of someone being cast onto the bottom or side of the pool. "The underwater environment. Is a very dynamic one, with many shadows and reflections dancing around, " says McQuade. The software does this by "projecting" a shape in its field of view onto an image of the far wall of the pool. It does the same with an image from another camera viewing the shape from a different angle. If the two projections are in the same position, the shape is identified as a shadow and is ignored. But if they are different, the shape is a swimmer and so the system follows its trajectory. "To pick out potential drowning victims, anyone in the water who starts to descend slowly is added to the software’s "pre-alert" list," says McQuade. Swimmers who then stay immobile on the pool bottom for 5 seconds or more are considered in danger of drowning. Poseidon double-cheeks that the image really is of a swimmer, not a shadow, by seeing whether it obscures the pool’s floor texture when viewed from overhead (在头顶上). If so, it alerts the lifeguard, showing the swimmer’s location on a poolside screen. The first full-scale Poseidon system will be officially opened next week at a pool in High Wycombe, Buckinghamshire. One man who is impressed with the idea is Travor Baylis, inventor of the clockwork(时钟机构) radio. Baylis runs a company that installs swimming pools — and he was once an underwater escapologist (表演脱身术的人) with a circus. "I say full marks to them if this works and can save lives, " he says. But he adds that any local authority spending ￡30,000-plus on a Poseidon system ought to be investing similar amounts in teaching children to swim. The word "considered" in paragraph 5 could be best replaced by

In today’s knowledge economy, nations survive on the things they do best. Japanese design electronics while Germens export engineering(工程) techniques. The French serve the best food and Americans make computers. 2. Britain specializes in the gift of talking. The nation doesn’t manufacture much of anything. But it has lawyers, stylists and business consultants who earn their living from talk and more talk. The World Foundation think tank says the UK’s four iconic (图标的)jobs today are not scientists, engineers, teachers and nurses. Instead, they’re hairdressers, celebrities, management consultants (顾问) and managers. But can all this talking keep the British economy going The British government thinks it can. 3. Although the country’s trade deficit was more than ￡60 billion in 2006, UK’s largest in the postwar period, officials say the country has nothing to worry about. In fact, Britain does have a world-class pharmaceutical(制药学的) industry and it still makes a small sum from selling arms abroad. It also trades services — accountancy, insurance, banking and advertising. The government believes Britain is on the cutting edge of the knowledge economy. After all, the country of Shakespeare and Wordsworth has a literary tradition of which to be proud. Rock’ n’ roll is an English language medium, and there are billions to be made by their cutting-edge bands. In other words, the creative economy has plenty of strength to carry the British economy. 4. However, creative industries account for only about 4 percent of UK’s exports of goods and services. The industries are finding it hard to make a profit, according to a report of the National Endowment for Science, Technology and the Arts. The report shows only 38 percent of British companies were engaged in "innovation activities", 3 percentage points below the EU average and well below Germany(61 percent)and Sweden(47 percent). 5. In fact, it might be better to call Britain a "servant" economy — there are at least 4 million people "in service". The majority of the population are employed by the rich to cook, clean, and take care of their children. Many graduates are even doing menial jobs for which they do not need a degree. Most employment growth has been, and will continue to be, at the low-skill end of the service sector — in shops, bars, hotels, domestic service and in nursing and care homes. A. Growth of Economy B. "Servant" Economy C. Strength of the Creative Economy D. Weakness of the Creative Economy E. Gift of Talking F. Export of Talking Machines Paragraph 3______
