"Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. "There is certainly a lot of energy in waves," he said.
Scientists are working to use that energy to make electricity. Most waves are created when winds blow across the ocean. "The wind starts out by making little ripples (涟漪), but if they keep on blowing, those ripples get bigger and bigger and turn into waves," Taylor said. "Waves are one of nature's ways of picking up energy and then sending it off on a journey."
When waves come toward the shore, people can set up darns to block the water and send it through a large wheel called a turbine (涡轮机). The turbine can then power an electrical generator to produce electricity.
"The resource is huge," said Janet Swain of the World-watch Institute. "We will never run out of wave power." Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three-quarters of the Earth's surface - that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.
Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic.
Traditional sources of energy like oil and gas may someday run out. "Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!

B. build more small power stations on the oceans

【解析】
At five he was collecting old newspapers to make money. And when he was 15 he signed his schoolmates up to start a baby-sitting circle.
Now 20, third-year Cambridge University student, Peter Blackburn is managing director of a company with a £ 30,000 plan. And he thinks it will make more than $15,000 by next summer. He set up Peter Blackburn Ltd last year to bring out a new, color term-planner that now students all over the UK are using.
"I felt that most of the planners going around were pretty unimaginative," he says, "I believed that I could do a better job and decided to have a go".
Blackburn admits that he is putting far more effort into business than his computer studies course at university. While fellow students are out with their friends, he keeps in touch with his business office in Lancashire by movable phone. Before he set up the company he spent one holiday preparing a plan that would persuade his bank to lend him money.
"Most students work hard for a good degree because they believe that will help them get a job to support themselves," he says "I work hard at my company, because that is what will support me next year, after I leave college."
Friends believe that Blackburn will make £ 1 million within 5 years. He is not quite so sure, however. "There's a lot to be done yet," he says.
