“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  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 dams 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 Worldwatch 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!

篇章导读：本文是一篇科普说明文，介绍了有关海洋波浪能源的应用前景及存在的问题。

13．The writer uses the two questions at the beginning of the passage to ________.

A．test the readers' knowledge about waves

B．draw the readers' attention to the topic

C．show Jamie Taylor's importance

D．invite the readers to answer them

14．The underlined phrase “picking up”  is closest in meaning to “________”．

A．starting again                      B．speeding up

C．improving                           D．gathering

15．It can be inferred that someday we might not worry about ________.

 A．our power supply                   B．our boat traffic

 C．air pollution                      D．our supply of sea fish

16．We can make better use of wave energy if we ________.

 A．shorten its journey to thousands of homes

B．build more small power stations on the oceans

 C．reduce the cost of turning it into electric power

D．quicken the steps of producing electricity

【回答】

13.B　推理判断题。作者在问题后谈到了波浪能源的相关内容，所以文章开头的两个问句是为了引起读者的注意，从而引出文章主题。故选B。

14.D　词义猜测题。本句中的“and then sending it off on a journey”是关键信息，it指代energy, send ... off意为“把……发散出去”，由此可知，前一动作是收集能源的过程。故picking up在此意为“收集”，与gathering同义。故选D。

15.A　细节理解题。由第二段前两句可知，资源很庞大，所以将来终有一天我们不必再为电力供应担忧。never run out of “永远不会用完”是关键信息。故选A。

16.C　细节理解题。根据第三段第一句“Swain said that wave power still costs too much money.”可知，波浪能源仍耗资很多。由此可知，如果我们能降低波浪能源的发电成本，我们将会更好地利用波浪能源。故选C。
