14、 by warm，circular currents of water under the ice，called eddies (漩涡)The eddies strong currents melt the ice at the edge，but weaker ones keep the center frozen.“Results of our field surveys show that there are warm eddies that circulate in a clockwise (顺时针的) direction under the ice cover，” said Alexe

15、i Kouraev，a hydrologist at the University of Toulouse，in a NASA statement.“In the eddy center，the ice does not melteven though the water is warmbecause the currents are weak，” he said.“But on the eddy boundary，the currents are stronger，and warmer water leads to rapid melting.”During field work，Koura

19、暖流漩涡；科学家们对漩涡的成因也有了初步判断，正在进一步的探索中。1Which word can best replace the underlined word “ephemeral” in paragraph 4?ASteady.BCurrent.CFundamental. DTemporary.解析：词义猜测题。第四段该句中，while表示对比，ephemeral与lasted for weeks or even months“持久的”意义相反，是“暂时的”；B项意为“现在的、目前的”，与“过去的(past)”和“将来的(future)”意义相对，所以不对。A、C则与while后文意义不

20、能形成对比。答案：D2Why is the ice in the center of ice rings frozen while that at the edge is melted?ABecause the center of ice rings is 2 to 4 warmer than the edge.BBecause the currents in the center are less powerful.CBecause it is too wide to be recognized or incited.DBecause water in the center circulat

21、es in a clockwise direction.解析：细节理解题。考查因果关系。从第二段第三句“In the eddy center，the ice does not melteven though the water is warmbecause the currents are weak”可知B项正确。因为暖流不够急促，所以造成只有冰的边缘才能溶解的现象；A项偷换概念，从第三段最后一句可知漩涡水温高于周边水温，不是冰环中心与边缘温差的比较，更不是题干原因；C项同样表述有误，从第四段第一句可知其讲述的是most of the rings，不是the ice in the center

24、aused by warm，circular currents.”；根据第二段第一句可知B项表述错误；根据第三段“Kouraev and his colleagues.set sensors capable of measuring the temperature and salinity of the water to a depth of 700 feet”可知D项偷换概念。答案：C4What maybe the best title for the text?AWhats Causing the Giant Ice Rings in Siberia?BThe Mystery of the

25、 Eddies in the Lake Baikal was Uncovered.CThe Largest and Deepest Freshwater LakeLake Baikal.DWhy Does the Edge of an Ice Ring Melt Faster?解析：标题归纳题。此文主要介绍了西伯利亚贝加尔湖多年的冰环之谜的答案在于冰面下方的暖流漩涡，所以选A。解答漩涡之谜，并非本文重点，只在最后提及而已，B项表述有误；C项的范围太大；D项范围缩小，不足以概括文章。答案：A.短文改错I have been decided to become a pilot since I am
