Question

閱讀理解 　　In summer, millions of people will head for the beach．And while the ocean can be a great place to swim and play, it may also be useful in another way．Some scientists think that waves could help make electricity． 　　“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave?Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland．“There is certainly a lot of energy in waves．” Scientists are working on using that energy to make electricity．Most waves are created when winds blow across the ocean．“The winds start out by making little ripples (波紋)in the water, 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 towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (渦輪)．The turbine can then power an electrical generator (發電機)．The United States and a few other countries have started doing research on wave energy, and it is already being used in Scotland．The resource is huge．We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal． 　　Oceans cover three quarters of the earth’s surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks, however．Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Plus, wave power would get in the way of fishing and boat traffic．With more research, however, “many of these problems might be overcome, ” Taylor said．“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day．” 　　In the future, when you turn on a light switch, an ocean wave could be providing the electricity! (1) Which of the following is NOT true? [　　] A． Wave power costs too much money． B． Wave energy creates the same amount of pollution as other energy sources． C． Wave power affects fishing and boat traffic． D． Wave power may affect marine animals． (2) We can infer from the passage that ________． [　　] A． finding new energy sources like wave energy is important B． wave energy is a resource that will never run out and is used all over the world C． wave power is perfect for creating energy around the world D． wave power doesn’t create any pollution (3) The underlined word “drawbacks” probably means ________． [　　] A． regrets B． adventures C． disadvantages D． difficulties (4) What can be the best title for the passage? [　　] A． How to Get Electricity by Waves B． A Huge Resource of Energy C． Can Waves Make Electricity? D． The Disadvantages of Wave Energy

Answer 1

答案：1．B;2．A;3．C;4．C;
解析：

(1)	波浪所發的電能不像其他形式的能源，它不會帶來很多的污染。
(2)	這種能源如何利用正在研究中，故B項錯誤。并非波能是最好的能，C項錯；波能也會帶來污染，但程度小，D項錯。
(3)	從倒數第四段中perfect和however可推知。
(4)	從整篇文章來看，波能是否能廣泛使用，還在試驗之中，所以C項最恰當。
