2015考研英语阅读英文原刊《经济学人》：模拟海啸

　　2015考研英语复习正是强化复习阶段，考研英语阅读在考研英语中占了40分，所以考研英语阅读是英语科目中重要的一项。新东方名师范猛老师曾建议过考研生需要坚持每天泛读10-15分钟的英文原刊。强烈推荐了杂志《经济学人》.杂志中的文章也是考研英语的主要材料来源.希望考研考生认真阅读，快速提高考研英语阅读水平。

　　Modelling tsunamis

　　模拟海啸

　　The dangers of insularity

　　岛国的危险

　　Islands may amplify the biggest waves, not breakthem

　　岛屿可能会增强海啸，而不会减弱海啸

　　SURFERS shun beaches shielded by islands off the coast.

　　冲浪者不会去海中的岛屿的沙滩上去冲浪。

　　That, as generations of swarthy, golden-haired hulks will tell you, is because such islandscreate a natural breakwater.

　　一代又一代的金发肤色黝黑的冲浪者会告诉你，那是因为这类小岛形成天然的防波堤。

　　Thisdampens waves and makes for a boringly calm surf best left to sunbathers.

　　这类岛屿的沙滩海浪较小，海面很平静，最适合晒日光浴的人了。

　　The surfers’ reasoning is sound for the short-wave, wind-generated swells that they ride.

　　较短、由风产生浪比较适合冲浪，对于这种浪来说，这种解释很合理。

　　But Themistoklis Stefanakis, of the Ecole Normale Superieure in Cachan, France, warns itmay not be true for the longer wavelengths of tsunamis.

　　但是，来自法国卡尚高等师范学校Themistoklis Stefanakis警告说，对于波浪较长的海啸来说，就不一样了。

　　As he and his colleagues show in a paper posted on arXiv, an online repository, littoral islandsmay actually exacerbate, rather than diminish, the effects of these waves.

　　如Themistoklis Stefanakis跟他的同事在线数据库arXiv发表的文章中所描述的的那样：实际上沿海的岛屿可能会增强长波浪的强度，而不是减弱。

　　Anecdotal evidence for this counterintuitive assertion comes from episodes where thesame tsunami has battered different types of coastal topography.

　　这种违反直觉的判断的轶事证据来自很少见的现象—同一海啸会造成不同的海岸地貌。

　　In 2010, for instance, when one hit the Mentawai islands in Indonesia, areas of coastlinedirectly behind islets bore the brunt of the damage, according to Costas Synolakis, atsunami expert at the University of Southern California who is one of the study’s co-authors.

　　例如，2010年印度尼西亚明达威岛遭遇的海啸，明达威岛后的海岸区域的破坏的最为严重，南加州大学的海啸专家Costas Synolakis这样说道，他是这篇文章的作者之一。

　　Dr Synolakis, Mr Stefanakis and their colleagues decided to try to put numbers on theirhunch.

　　博士Synolakis Mr Stefanakis及他们的同事，决定验证这个设想。

　　Rather than valiantly staking out seafront locales, though, they tested the idea with acomputer model.

　　他们想到用电脑模拟的方法来实验，而不是在海岸实验。

　　This is harder than it sounds.

　　实际做起来要比听起来难很多。

　　Simulating the way waves behave as they make landfall means taking account of, literally,oceans of data.

　　要模拟当海浪到大陆地时海浪的运动就意味着要严格地考虑到海洋的信息。

　　To simplify the problem, the researchers looked at what happens when a computerisedwave encounters a cone-shaped island on a smoothly sloping seabed in front of a straightcyber-coastline with a beach that continues to rise smoothly as it progresses inland.

　　为了简化问题，在带有海滩的笔直虚拟海岸线可平滑上升的情况下，研究人员观察当模拟的的海浪在平滑的斜海床上与锥形岛屿相遇时，会发生什么。

　　These approximations allow a computer to cope with the problem, yet are sufficiently similarto many real places for the conclusions drawn from them to, as it were, hold water.

　　电脑在处理这类问题时，这种近似可以忽略，然而这跟之前认为得减弱海浪的结论已经很相似了.

　　The team made their virtual islet jut out of the ocean to an altitude of 100 metres, a typicalheight above sea level for such outcrops.

　　研究组将模拟的岛屿拉高到海平面100米的位置,许多岛屿超出海平面也就是100米。

　　They then looked at 200 combinations of gradients for the sides of the island, the seabed andthe beach; the distance between the island and the beach; and the wavelength of theencroaching tsunami.

　　他们将岛屿、海床、沙滩的外围的倾斜度，岛屿和沙滩的距离，海啸的波长做了200种组合来实验观察。

　　In none of these did an island offer any succour to the coastline behind it. Instead, it actedas a lens, focusing the wave’s destructive power and amplifying its size by between 5% and70%.

　　没有一类能有助于减弱海啸。实际上，它好比一个透镜，将海浪的破坏力聚集起来，并且扩大5%-70%。

　　The upshot is that, far from shielding a coastline, offshore islands can make thingsworse—information that should be incorporated into tsunami evacuation plans.

　　结果是。沿海的岛屿不会保护海岸区域不受破坏，反而会让其更糟。这在海啸救援中应当将其考虑在内。

　　For if a big wave is coming, running from it is not enough. You also have to know how far torun before it is safe to stop.

　　如果海啸来临，跑是不够的。还应该知道跑多远才是安全的。
