　　Why did the chicken cross the road? To get to the other side．

　　Most people know this joke．But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road．

　　“Millions of animals die each year on U．S．roads,” the Federal Highway Administration reports．In fact, only about 80 ocelots, an endangered wild cat, exist in the U．S．today．The main reason? Roadkill．

　　“Eco-passages” may help animals cross the road without being hit by cars．They are paths both over and under roads．“These eco-passages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society．

　　But do animals actually use the eco-passages? The answer is yes．Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway．This showed that the lions used the passage．

　　Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them．Animals seem to be catching on．Animals as different as salamanders and grizzly bears are using the bridges and underpasses．

　　The next time you visit a park or drive through an area with a lot of wildlife, look around．You might see an animal overpass!

　　ECO-friendly technology was the hottest trend at the 39th Tokyo Motor Show, which opened last Friday．

　　About 240 car manufacturers from 13 countries presented new models．Most were powered by hybrid(混合的), fuel cell(燃料电池)and electrical systems．Carmakers are championing more environmentally models amid increasing oil prices and environmental concerns．

　　“It's now carmakers' social responsibility to protect the environment,”said Mazda president Hisakazu Imaki．

　　Seventy-nine cars and motorcycles are being presented to the public for the first time, according to the Japan Automobile Manufacturers Association．

　　The organizing association said the biennial(两年一次的)show, due to end on November6,was sure to have a large impact on the automobile industry．

　　Manufacturers are currently competing in the shift from gasoline-run engines to hybrid, fuel cell or electricity-powered systems．

　　Mazda has a new sports vehicle, which runs on a hybrid electric-petrol system．It is also showing a gasoline-hydrogen run sports car．

　　A member of the Ford family, Mazda plans to market a hybrid version of the Tribute sport utility vehicle(SUV)next spring and enhance its co-operation with Ford in hybrid systems development．

　　Honda's fuel cell sedan(轿车)on show uses a hydrogen-oxygen fuel．The system only sends water out its exhaust(尾气), a better solution for the environment and less polluting than hybrids．
