While car sharing is a concept that' s catching on, old-fashioned carpooling where a group of people take turns driving each other to work has always faced a resistance (抗拒). In a study on traffic problems by ABC News, 84% of those who drive to work say that they still do it alone. More than half of those lone riders insist that carpooling is just too inconvenient, and 18% say they simply don' t know anyone to share a ride with. Now technology makes carpooling easier and more fun. NuRide, a company provided an online carpooling service last year, offers daily travelers in the Washington area not just a web-based list of would-be carpoolers but also a way to arrange a trip online. Here' s how it works: rider seekers enter the positions where their trip will begin and end, the time they want to leave and if they' re willing to drive or just ride in someone else' s car. The website' s search engine then looks for matches and makes lists of the names of traveling companions, along with the car model and the exact time and place to meet for each trip. People who want to share the ride can show their interest in joining in online and then meet their car mates when it' s time to go. NuRide users aren' t riding with total strangers. They are required to provide the name of their employer and a work e-mail address, both of which need to be checked before being listed on the website. To attract users, NuRide offers a frequent rider prize: anyone who shares a ride gets a $1 credit. So far, 2,300 people have signed up. NuRide CEO Rick Steele said that more than 50,000 rides have been arranged on the website, resulting in 1.4 million fewer miles driven and 650 fewer tons of automobile emissions(机动车排放).

I'm told that during an international game of chess (国际象棋), many beautiful moves could be made on a chessboard. In a decisive【C1】______ in which he was evenly matched with a Russian master【C2】______ , Marshall found his queen under serious attack. There were several ways of【C3】______ , and since the queen is the most【C4】______ piece, spectators (观众) thought Marshall would naturally move his queen to【C5】______ . Deep in thought, Marshall used all his time to consider the【C6】______ . He picked up his queen, paused, and placed it down on the most【C7】______ square of all—a square from which the queen could be【C8】______ by any one of three enemy pieces. Marshall had sacrificed (牺牲) his queen—an unthinkable move. Everyone else was【C9】______ . Then the Russian, and the【C10】______ , realized that Marshall had actually made a【C11】______ move. It was clear that no matter how the【C12】______ was taken, the Russian would soon be in a【C13】______ position. Seeing this, the Russian admitted his defeat. When spectators recovered from the【C14】______ of Marshall's daring, they showered the chessboard with money. Marshall had achieved【C15】______ in a very unusual and daring fashion—he had【C16】______ by sacrificing the queen. To me, it's not【C17】______ that he won. What counts is that Marshall had broken with standard【C18】______ to make such a move. He had looked【C19】______ the usual patterns of play and had been willing to consider an imaginative risk on the basis of his judgment and his judgment alone. No matter how the game【C20】______ , Marshall was the winner.

There are a growing number of pet owners who feed pets on raw, which means, "uncooked" meat and bones. William Burk, a pet food specialist from the Food and Drug Administration (FDA) , believes that feeding raw meat to pets is against its goal of protecting the public from health dangers; besides, raw meat and bones do not have all the required nutrition(营养)that a pet needs every day. Recognizing how popular these foods are, the FDA has provided guidelines for producers of pet foods that contain uncooked meat for dogs, cats, and other pets. The guidelines give rules to protect pet owners and pets from dangers about food safety and lack of nutrition. Pet owners who feed raw meat and bones should deal with these products very carefully to protect themselves against possible dangers, says Burk. Just as when preparing foods for humans, use hot water and soap to wash hands, containers, and surfaces that come into contact (接触) with the food. Don't put your hands near your mouth until you've washed them, and don' t allow your pet to touch your face right after it has eaten meat. If owners choose to feed bones to their pets, they should watch their pet carefully when it is eating bones. Burk also says, "If the pet eats a big piece of bone that won't pass through the digestive system(消化系统) , it could kill the pet."

Your dog is as smart as any two year old, according to a new study. Dogs bring much happiness to their owners, and even improve human health. Most two year olds keep us busy in life—an important part of living a long and happy life. According to Stanley Coren, Ph. D. of the University of British Columbia, our dogs are smarter than we thought. Dr. Coren reviewed many studies to find out that dogs are as smart as 2 to 2. 5 year olds. Forget about one word orders—according to Coren, the smartest dogs can learn up to 250 words. Most dogs understand an average of 165 words. " The upper limit of dogs' ability to learn language is partly based on a study of a Border Collie(博得牧羊犬) named Rico who showed knowledge of 200 spoken words, and ' fast-track learning,' which scientists believed to be found only in humans and language-learning apes(猿). " Dogs are also great at tricking. During play, they have the ability to trick humans and other dogs in order to get treats. "And they are nearly as successful in tricking humans as humans are in tricking dogs," says Coren. Dogs can also count to four or five, which might explain how they know when their toys are missing. Coren explains, "Their astonishing flashes of smartness and creativity (创造力) are reminders that they may not be Einsteins, but are sure closer to humans than we thought. " Animals can do much to keep us happy, healthy, and protect us from harm. Stories of dog heroes can be found using a simple Internet search. Pets teach us sense of duty, keep us from loneliness, and can help with treatment of the disabled. Dogs are smarter than we thought—as smart as a two year old.

People today expect to be examined when they enter a doctor's office. At least they expect their blood pressure and temperature to be measured. However, as recently as two hundred years ago, a doctor's treatment depended on talking with patients. In general, the communication between doctors and their patients was the most important part of medical methods. The modern age of medicine began with the stethoscope, an instrument for listening to patients' heartbeat and breathing. Before that, a doctor did not touch a patient. In fact, there was no such thing as a medical examination. The stethoscope—with all other medical instruments—has a serious effect on the practice of medicine. Doctors become better at finding the medical problems. More lives are saved. At the same time, doctors give less importance to the communication between patients and doctors. Some doctors actually stop talking to their patients. It is easy to understand why some sick people thought themselves as broken machines.
