剑8 test3,Reading Passage 2,summary,全文概括：潮汐能（Tidal Power）对于英国的作用及重要性，还有关于潮汐能的介绍。 题型：Question 14-17是段落信息匹配题 Question 18-22是多选题 Question 23-26是图标题,生词,turbine n.涡轮 blade n. 叶片，刀片 propeller n. 螺旋桨 drastically adv.彻底地 self-sufficient adj.自给自足的 coal n.煤 ailing adj.生病的 subsidiary n. 子公司 indented adj. 犬牙交错的 cable n. 缆绳；电缆,maintenance n. 维护，维修 Cavitation n. 气穴现象 bubble n. 气泡 Vibration n. 振动 Submerge vt. 淹没 Debris n. 碎片 Robust adj. 强健的 stick out 突出,q14,题目解析 我们需要抓住题干中的location和first 答案句：The first station is expected to be installed off Lynmouth in Devon shortly to test the technology in a venture jointly funded by the department of Trade and Industry and the European Union.（C段第二句） 定位词：location，first 答案：C,q15,题目解析 题干中说的是一种把生产在某处的能源带回英国的方式，很明显能对应到E段。 答案句：Dr Bahaj has done most work on the Alderney site, where there are powerful currents. The single undersea turbine farm would produce far more power than needed. and be re-imported into Britain via the cable under the Channel.（整个E段） 定位词：back 答案：E,q16,题目解析 题干问的是英国以前曾尝试寻找可供选择的能源，也很明显能找到出处。 答案句：Unlike wind power, which Britain originally developed and then abandoned for 20 years . undersea turbines could become a big export earner to island nations such as Japan and New Zealand.（A段最后一句） 定位词：previous，alternative 答案：A,q17,题目解析 这题要注意大题目中有个NB：You may use any letter more than once.题干说的是哪里提到了来自另一产业的应用技术 答案句：The technology for dealing with the hostile saline environment under the sea has been developed in the North Sea oil industry and much is already known about turbine blade design, because of wind power and ship propellers.（C段第4句） 定位词：another industry，applying technoligy 答案：C,Q18,题目解析 题干中的wind power在A段出现得比较多，仔细阅读便能发现跟题干相似的意思wind在此句中以原形出现，而reliable被替换为predictable和constant。 答案句：. unlike wind, the tides are predictable and the power input is constant.（A段第一句） 定位词：reliable 答案：A,q19,题目解析 这题也是多选题的一题，因此还是同义转换的套路drastically reducing替换了D选项中的cut down，而carbon dioxide emissions为二氧化碳的排放，也就是对于空气的污染。 答案句：The technology raises the prospect of Britain becoming self-sufficient in renewable energy and drastically reducing its carbon dioxide emissions.（A段第二句） 定位词：cut down，air pollution 答案：D,q20,题目解析 题干说的是潮汐能会让许多英国现有的能源设备关闭。closure为close的名词形式，而gas, coal and nuclear power plants都是现有的旧能源发电站，也就是existing power stations。 答案句：If tide, wind and wave power are all developed, Britain would be able to close gas, coal and nuclear power plants and export renewable power to other parts of Europe.（A段第三句） 定义词：closure，existing 答案：E,q21,题目解析 题干说的是这会成为一种增加国家收入的方式。export earner与选项中increasing national income意思相同。 答案句：. Britain . undersea turbines could become a big export earner to island nations such as Japan and New Zealand.（A段最后一句） 定位词：income 答案：F,q22,题目解析 题干说的是潮汐能源站最好建在具有特定特征的邻近海岸线。原文中也有对应句 答案句： The best sites are between islands or around heavily indented coasts where there are strong tidal currents.（C段最后一句） 定义词：best，coastline 答案：J,q23,题目解析 题干中的raise和extraction与原文中的stick out和clean相对应，借助空格前面的介词就可以选定答案。 答案句：The towers will stick out of the water and be lit, to warn shipping, and also be designed to be lifted out of the water for maintenance and to clean seaweed from the blades.（D段最后一句） 定位词：raise，extraction 答案：maintenance,Q24,题目解析 题干中fish and other creatures就是sea life, unlikely to be at risk替换了not in danger。通过题目判断此空格应填形容词，与blades为直接的修饰关系。 答案句：Fish and other creatures are thought unlikely to be at risk from the relatively slow-turning blades.（D段第四句） 定位词：sea life 答案：slow,Q25+Q26,题目解析 题干中的Air bubble直接在原文中有出现，直接定位就能找到答案。而且后面由is known as能看出要填一个能概括的词，极可能是专业名词，明显在段首就有。 答案句：One technical difficulty is cavitation, where low pressure behind a turning blade causes air bubbles.（F段第一句） 定位词：Air bubble 答案：low pressure，cavitation,technique,这篇文章是一篇涉及能源和科技的说明文，难度不大。从解析来看，很多答案出现在某段的段首或段尾，不妨我们以后可以在理解文章大意的基础上再去这些地方寻找到答案，能节省不少时间。,
