2014 届高考英语二轮专题复习阅读理解极限突破测试卷(4)<br />阅读理解------A<br />According to the US government, wind farms off the Pacific coast could produce <br />900 gig watts of electricity every year. Unfortunately, the water there is far too <br />deep for even the tallest windmills (see picture) to touch bottom. An experiment <br />under way off the coast of Norway, however, could help put them anywhere.<br />The project, called Hywind, is the world’s first large-scale deepwater wind <br />turbine(涡轮发电机 ).Although it uses a fairly standard 152-ton,2.3-megawatt <br />turbine, Hywind represents totally new technology. The turbine will be fixed 213 <br />feet above the water on a floating spar(see picture),a technology Hywind’s creator, <br />the Norwegian company StatoilHydro, has developed recently. The steel spar, which <br />is filled with stones and goes 328 feet below the sea surface, will be tied to the <br />ocean floor by three cable(缆索)；these will keep the spar stable and prevent the <br />turbine from moving up and down in the waves. Hywind’s stability(稳定性)in the cold <br />and rough sea would prove that even the deepest corners of the ocean are suitable <br />for wind power. If all goes according to plan, the turbine will start producing <br />electricity six miles off the coast of southwestern Norway as early as September.<br />To produce electricity on a large scale, a commercial wind farm will have to <br />use bigger turbines than Hywind does, but it’s difficult enough to balance such <br />a large turbine so high on a floating spar in the middle of the ocean. To make that <br />turbine heavier, the whole spar’s to design a new kind of wind turbine, one whose <br />gearbox(变速箱) sits at sea level rather than behind the blades (see picture )<br />Hywind is a test run, but the benefits for perfecting floating wind-farm <br />technology could be extremely large. Out at sea, the wind is often stronger and <br />steadier than close to shore, where all existing offshore windmills are planted. <br />Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore <br />objection. If the technology catches on, it will open up vast areas of the planet’s <br />surface to one of the best low-carbon power sources available.<br /> <br /> ( ) 1. The Hywind project uses totally new technology to ensure the stability of <br />_______.<br />A. the cables which tie the spar to the ocean floor<br />B. the spar which is floating in deep-sea water<br />C. the blades driven by strong and steady sea wind<br />D. the stones filled in the spar below the sea surface<br />( ) 2. To balance a bigger turbine high on a flatting spar, a new type of turbine <br />is to be designed with its gearbox sitting ____________.<br />A. on the sea floor B. on the spar top<br />C. at sea level D. behind the blades<br />( ) 3. Wide applications of deepwater wind power technology can ____________.<br />A. solve the technical problems of deepwater windmills<br />B. make financial...
