  新托福阅读背景知识:南极。英国科学家日前正式宣布,传说中的尼斯湖水怪并不存在,他们用声纳和卫星设备把尼斯湖梳理了一遍,并没有发现怪物的踪影。
  新托福阅读部分的准备工作。这个由英国广播公司(BBC)资助的研究小组,在搜寻行动开始时满怀信心地认为苏格兰传说中描绘的“怪物”一定存在。他们猜测所谓的怪物是一种古代海洋爬行动物蛇颈龙。它们与恐龙一起在一次小行星撞击地球后灭绝。大约半月前,一名苏格兰人在尼斯湖岸边发现了蛇颈龙脊柱的化石。这证明,古代这一地区有蛇颈龙出没。
  A recent, unprecedented river run on the Congo yielded a raft of new discoveries, including different speciessome potentially newin nearly every nook and cranny, scientists announced this week.
  The river was also found to be possibly the world‘s deepest, and its extraordinary changes in depths and currents help explain why it‘s such a hotbed of fish diversity.
  What we‘re seeing here is kind of evolution on steroids, said team leader Melanie Stiassny, a fish biologist at the American Museum of Natural History. Stiassny, a member of the National Geographic Society‘s Conservation Trust, was among the marine and evolutionary biologists, hydrologists, and kayakers who conducted the exhaustive research in summer 2008.
  Despite calmer stretches like the one photographed above in summer 2008, the Congo is the world‘s highest-volume white-water river, according to Trip Jennings, a National Geographic Expeditions Council grantee.
  As part of a 2008 expedition, Jennings and his team of kayakers navigated the churning river‘s powerful whirlpools.
  The six of us were tossed about like pool toys in a hurricane, Jennings said. Giant whirlpools threatening to suck us under spawned without warning, and oceanlike breaking waves crashed on us from all sides.
  During a survey of Congo fish, Stiassny found seemingly different species just a few hundred meters apart. Some had developed flatter bodies to avoid being pulled by the current, for example. Likewise, living in a low-visibility, sediment-filled stretch of the river, the African electric catfish had evolved the ability to stun nearby prey with up to 350 volts of electricity.
  英国苏格兰北部的尼斯湖(Loch Ness)一直传有水怪,最近有地质学家指尼斯湖根本没有水怪。
  意大利地质学家皮卡尔迪在伦敦及美国地质学会合办的会议发表其理论。他表示,近年数千宗所谓的目击水怪事件,内容只有几点是相同的,包括“水怪”在湖面造成水花四溅和水流乱湍,这些跟地震造成的很相似。
  他指出,尼斯湖正位于一个断层之上,只要轻微的地震,都会在湖面造成各种的效果,如水流乱湍和产生大水泡等。尼斯湖形状狭长,宽度平均一点六公里,深度有两百多公尺,水温低而湍急。
