Questions 14-17

题型：段落信息配对题MATCHING
解析：此题工作量大，费时多，解题时不建议此类题。在读题过程中把每一个信息句中的主要名词标注出来，到文章每一段中仔细地搜寻。注意：有的段落会被选两次。

14.

定位词 / 关键词	location, first test site
原文定位	C段二句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.
题解	此题的定位名词有特殊性，location暗示她名，而first暗示排序，很难替换，因此几乎是原封不动地出现在原文中。
答案	C

15.

定位词 / 关键词	one site, back into Britain
原文定位	E段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.
题解	one site的具体名字就是此段中提到的Alderney site,而re-imported表示再重新进口回英，也就是题目中提到的back into Britain。
答案	E

16.

定位词 / 关键词	previous attempt by Britain, alternative source of energy
原文定位	A段后一句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.
题解	由此句可知，英曾经图发展风能但终还是放弃了，也就是对应了英曾经做过previous attempt,而那个alternative source of energy就是风能。
答案	A

17.

定位词 / 关键词	applying technology, another industry
原文定位	C段四句The technology for dealing with the hostile saline environment i 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.
题解	题目中的another industry就是文章中的oil industry，而applying technology被转换为the technology ... has been developed in … oil industry。
答案	C

Questions 18-22

题型：多选题MULTIPLE CHOICE
解析：此题为多选题，问作者对于主题的陈述哪些是正确的，这种题是很难定位的。建议细读选项，将选项中的名词标为重点，再到文章中核对，注意同义替换比较频繁。
18.

定位词 / 关键词	reliable, than wind power
原文定位	A段句 ... unlike wind, the tides are predictable and the power input is constant.
题解	wind在此句中以原形出现，而reliable被替换为predictable和constant。
答案	A

19.

定位词 / 关键词	cut down, air pollution
原文定位	A段二句The technology raises the prospect of Britain becoming self-sufficient in renewable energy and drastically reducing its carbon dioxide emissions.
题解	reducing和D选项中的cut down为同义替换，而carbon dioxide emissions为二氧化碳的排放，也就是对于空气的污染。
答案	D

20.

定位词 / 关键词	closure of many existing power stations
原文定位	A段三句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.
题解	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	E

21.

定位词 / 关键词	increasing national income
原文定位	A段后一句 ... Britain ... undersea turbines could become a big export earner to island nations such as Japan and New Zealand.
题解	export earner意为“可赢取出口利润”，与选项中increasing national income“能够增加收入”意思相同。
答案	F

22.

定位词 / 关键词	best, in the vicinity of coastlines
原文定位	C段后一句The best sites are between islands or around heavily indented coasts where there are strong tidal currents.
题解	此句意为“佳的选址就在岛屿之间或者是非常迂回的海岸线附近……”，和选项完全吻合。
答案	J

Questions 23-26

题型：图表题DIAGRAM
解析：此类题型除了要注意图中所给的名词定位以外，还要注意图形中的方位和图形特点。如果填空题中有介词，也可以借助介词进行定位。此题可能无序。注意字数限制。

23.

定位词 / 关键词	tower, for, seaweed, blades
原文定位	D段后一句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.
题解	tower，seaweed，blades都可以锁定在这句话里，那么借助空格前面的介词就可以选定答案。
答案	maintenance

24.

定位词 / 关键词	sea life, not in danger, blades
原文定位	D段四句Fish and other creatures are thought unlikely to be at risk from the relatively slow-turning blades.
题解	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	slow (turning)

25&26..

定位词 / 关键词	air bubbles, behind, is known as
原文定位	F段句One technical difficulty is cavitation, where low pressure behind a turning blade causes air bubbles.
题解	由air bubbles锁定这句话，而介词behind可以直接暗示25题的答案。而26题要填写的是整个事件的总称，也就是原文中由where引导的定语从句的先行词。
答案	low pressure；cavitation

阅读难句解析

1.  Operating on the same principle as wind turbines, the power in sea turbines comes from tidal currents which turn blades similar to ships' propellers, but, unlike wind, the tides are predictable and the power input is constant.
解析：此句的主干是the power comes from tidal currents，其中operating on the same principle as wind turbines用于修饰主语the power，是主语所发出的动作，在句中作伴随状语。而which turn blades similar to ships' propellers是定语从句，修饰tidal currents。
参考翻译：同风能涡轮的原理一样，海洋涡轮的能量来自于潮汐洋流推动像船桨一样的涡轮叶片。但是，不同于风能的是，潮汐是可预知的，能量输入是稳定的。

2. 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 for the Channel Islands and most would be fed into the French Grid and be re-imported into Britain via the cable under the Channel.
解析：句中的where引导的从句为定语从句，先行词是Alderney site。二句中的needed for the Channel Islands是一个省略的定语从句，省略了引导词和动词that is；而此句中的两个被动语态be fed into和be re-imported into是由主语发出的两个动作，其中主语most是代词，表示“大部分”，相当于most power。
参考翻译：Bahaj博士已经做了关于奥尔德尼岛的大多数研究，那里有非常强的洋流。单一的海底涡轮组所产生的电量就已经远远超出了海峡岛屿的需求，大多数还会被送往法电网，然后通过海底电缆再重新进口到英。
