题文

阅读理解。 According to the US government, wind farms off the Pacific coast could produce 900 gig watts of electricity every year. Unfortunately, the water there is far too deep    for even the tallest windmills (e picture) to touch bottom.An experiment under way off the coast of Norway, however,could help put them anywhere.

The project, called Hywind, is the world's first large-scale deepwater wind turbine (涡轮发电机). Althoughit us a fairly standard 152-ton, 2.3-megawatt turbine, Hywind reprents totally new technology. The turbinewill be fixed 213 feet above the water on a floating spar (e picture), a technology Hywind's creator, the Norwegian company StatoilHydro,has developed recently. The steel spar, which is filled with stones and goes 328 feet below the a surface, will be tied to the ocean floor by three cable (缆索); the will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywind's stability (稳定性) in the cold and rough a would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway aarly as September. To produce electricity on a large scale, a commercial wind farm will have to u bigger turbines than Hywind does, but it's difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spar's to design a new kind of wind turbine, one who gearbox (变速箱) sits at a level rather than behind the blades (e picture).     Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at a, the wind is often stronger and steadier than clo to shore, where all existing offshore windmills are planted. Deep-a farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If thetechnology catches on, it will open up vast areas of the planet's surface to one of the best low-carbon power sources available.

考点

据考高分专家说，试题“阅读理解。.....”主要考查你对 [健康环保类阅读 ]考点的理解。 健康环保类阅读

健康环保累阅读概念：

健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。

健康环保类文章阅读技巧：

   健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：   第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；   第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；   第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。   从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。【阅读策略】 1、概要(Summarizing)：  阅完材料后，将所阅材料浓缩，摘要，做出所阅材料的书面或口头梗概。 2、组织(Organization)：  阅读后根据阅读内容，识别观点、人物、事件之间的关系以及文章的结构关系。如：时间关系、比较或对比关系、相关关系及因果关系等。
