单选题{{B}}第三篇{{/B}} {{B}} More Than a Ride to School{{/B}} The National Education Association claims, "The school bus is a mirror of the community." They further add that, unfortunately, what appears on the exterior does not always reflect the reality of a chosen community. They are right -- sometimes it reflects more! Just ask Lies! Denson. Riding the school bus has been more than a ride to school for Lies!. Bruce Hardy, school bus driver for Althouse Bus Company has been Liesl's bus driver since kindergarten. Last year when Liesl's family moved to Parkesburg, knowing her bus went by her new residence, she requested to ride the same bus. This year Liesl is a senior and will enjoy her last year riding the bus. She says, "It's been a great ride so far! My bus driver is so cool and has always been a good friend and a good listener. Sometimes when you're a child adults do not think that what you have to say is important. Mr. Hardy always listens to what you have to say and makes you feel important." Her friends Ashley Batista and Amanda Wolfe agree. Bruce Hardy has been making Octorara students feel special since 1975. This year he will celebrate 30 years working for Althouse Bus Company. Larry Althouse, president of the company, acknowledges Bruce Hardy's outstanding record: "You do not come by employees like Bruce these days. He has never missed a day of work and has a perfect driving record. He was recognized in 2000 by the Pennsylvania School Bus Association for driving 350,000 accident free miles. Hardy's reputation is made further evident through the relationships he has made with the students that ride his bus." Althouse further adds, "AIthouse Bus Company was established 70 years ago and has been providing quality transportation ever since. My grandfather started the business with one bus. Althouse Bus Company is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come." Three generations of business is not all the company has enjoyed. Thanks to drivers like Bruce Hardy, they have been building relationships through generations. Liesl's mother Carol also enjoys fond memories of riding Bruce Hardy's bus to the Octorara School District.

单选题Moral Issues One of the virtues in American culture is to help others. Christmas in America means different things to different people. To some people, Christmas means brightly wrapped packages under a decorated tree. To others, it means family reunions and a wonderful meal together. Christmas also means lending a helping hand to people in need. Along with all the hubbub of shopping for presents and sending Christmas cards, many people in America take time to help others. In America and around the world, Christmas offers many opportunities to spread "Peace on earth, good will toward men". For example, Salvation Army bell ringers are a familiar sight to most Christmas shoppers. They stand outside malls and stores collecting money for the needy. Many churches and other organizations collect toys and clothes as Christmas gifts for poor families. The Christmas spirit encourages people to help each other in many large and small ways. The spirit of helping others isn't limited to Christmas. However, Americans help others year-round. Civic clubs such as the Lion's Club, the Elk's Club and the Rotary Club take part in local community projects. Many organizations exist just to help others. The Make a Wish Foundation gives terminally ill children a chance to have their dream come true. Habitat for Humanity helps poor people build their own houses. And besides supporting worthy causes with their money, thousands of Americans donate their time by serving as volunteers in hospitals, homeless shelters and schools. Another virtue Americans respect is perseverance. Remember Aesop's fable about the turtle and the rabbit that had a race? The rabbit thought he could win easily, so he took a nap. But the turtle finally won because he did not give up. Compassion may be the queen of American virtues. The story of "The Good Samaritan" from the Bible describes a man who showed compassion. On his way to a certain city, a Samaritan man found a poor traveler lying on the road. The traveler had been beaten and robbed. The kind Samaritan, instead of just passing by, stopped to help this person in need. Compassion can even turn into a positive cycle. In fall, 1992, people in Iowa sent truckloads of water to help Floridians hit by a hurricane. The next summer, during the Midwest flooding, Florida returned the favor. In less dramatic ways, millions of Americans are quietly passing along the kindness shown them. In no way can this brief description cover all the moral values honored by Americans. Courage, responsibility, loyalty, gratitude and many others could be discussed. In fact, Bennett's best-seller over 800 pages highlights just l0 virtues. Even Bennett admits that he has only scratched the surface. But no matter how long or short the list is, moral values are invaluable. They are the foundation of American culture and any culture.

单选题Peel Watch Swimmers can drown in busy swimming pools when lifeguards fail to notice that they are in trouble. The Royal Society for the Prevention of Accidents says that on average 15 people drown in British pools each year, but many 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 monitoring station and a lifeguard"s pager. "In trials 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，轨线). 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-checks 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. 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 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 230,000—plus on a Poseidon system ought to be investing similar amounts in teaching children to swim.
