单选题The idea of a fish being able to generate electricity strong enough to light lamp bulbs— or even to run a small electricmotor— is almost unbelievable, but several kinds of fish are able to do this. Even more strangely, this curious power has been acquired in different ways by fish belonging to very different families. Perhaps the best known are the electric rays, or torpedoes (电鳐), of which several kinds live in warm seas. They possess on each side of the head, behind the eyes, a large organ consisting of a number of hexagonal shaped cells rather like a honeycomb. The cells are filled with a jelly-like substance, and contain a series of flat electric plates. One side, the negative side, of each plate, is supplied with very fine nerves, connected with a main nerve coming from a special part of the brain. Current passes from the upper, positive side of the organ downwards to the negative, lower side. Generally it is necessary to touch the fish in two places, completing the circuit, in order to receive a shock. The strength of this shock depends on the size of the fish, but newly born ones only about 5 centimetres across can be made to light the bulb of a pocket flashlight for a few moments, while a fully grown torpedo gives a shock capable of knocking a man down, and, if suitable wires are connected, will operate a small electric motor for several minutes. Another famous example is the electric eel. This fish gives an even more powerful shock. The system is different from that of the torpedo in that the electric plates run longitudinally (纵向) and are supplied with nerves from the spinal (脊骨) cord. Consequently, the current passes along the fish from head to tail. The electric organs of these fish are really altered muscles and like all muscles are apt (likely) to tire, so they are not able to produce electricity for very long. The power of producing electricity may serve these fish both for defence and attack.

单选题Raymond A. Moody, Jr. , a Georgia physician, credits his sense of humor for getting him through the terrible grind of medical school. Yet not once, in all those years of training, did professor Moody bring up the health benefits of laughter? "As time went on," Moody relates in his book Laugh After Laugh: The Healing Power of Humor, "I came to feel that a human being' s ability to laugh is just as valid an indicator of his health as are all those other things that doctors check." Gradually, many members of the medical establishment are coming around to the same thinking. Dr. William Fry,Jr. , a Stanford University researcher, has studied the beneficial effects of laughter for more than 30 years. "When we laugh," Fry explains, "muscles are activated. When we stop laughing, these muscles relax. Since muscle tension magnifies pain, many people with arthritis, rheumatism and other painful conditions benefit greatly from a healthy dose of laughter. Many headache sufferers feel the same relief." How can we all get more laughter into our lives? Here' s what the experts prescribe: Mix with people who laugh. Nancy Alguire, a teacher in Clifton Park, N.Y. was once painfully shy and had a hard time laughing. Then she married a circus enthusiast. "I became intrigued with the clowns," she recalls. "One day I put on a costume and asked a clown to paint my face. That afternoon my whole life changed. I learned to laugh and enjoy life in a way I had never done before." She went on to teach clowning at a local community college. To this day, she says, "I still make a point of mixing with people who enjoy life and laughing--because their joy rubs off on those around them." To help get humor-minded people together, several "laughter clubs" have sprung up around the country. Virginia Tooper, who publishes a newsletter called "Laugh Lovers News," tells of four typical women who gather for a restaurant lunch every Thursday in Phoenix. Each comes armed with at least one funny experience from the week, and the storyteller who receives the biggest laugh gets a free lunch-paid for by the others.

单选题{{B}}Part A{{/B}} {{B}}Text 1{{/B}} Burn rate is the speed at which a startup business consumes money. My rate would be $50,000 a month when my new media company started. So, I began looking around for individuals who would be my first investors. "Angel money" it was called. But when I reviewed my list of acquaintances to find those who might be able to help, I found the number got small. With no other choices, I began meeting with the venture-capital companies. But I was warned they took a huge share of your company for the money they put in. And if you struggled, they could drop you cold. As I was searching for "angel money", I started to bulid a team who trusted me even though I didn't have money for paychecks yet. Bill Becket was an expert in computer programming and image processing at a very famous Media Lab at M. I. T. With his arrival, my company suddenly had a major technology "guy" in house. Katherine Henderson, a filmmaker and a former real-estate dealer, joined us as our director of market research. Steve White came on as operating officer. He had worked for the developer of a home-finance software, Quicken. We grabbed him. We had some really good people, but we still didn't have enough money. One night, my neighbor, Louise Johnson, came for a visit. She and I were only nodding acquaintances, but her boys and ours were constant companions. She ran a very good business at the time. Louise was brilliant and missed nothing. She had been watching my progress closely. She knew I was dying for money and I had prospects but could offer no guarantees of success. She told me that her attorney had talked to mine and the terms had been agreed upon. She handed me an envelope. Inside was a check for $ 500,000. I almost fell down. I heard her voice as if from heaven. "I have confidence in your plan," she said. "You'll do well. You're going to work hard for it, but it's satisfying when you build your own company." Who would have thought I'd find an angel so close to home? There were no words sufficient for the moment. We just said good night. She left and I just stood there, completely humbled and completely committed.
