问题    The world’s greatest snow-capped peaks, which run in a chain from the Himalayas to the Tianshan Mountains on the border of China and Kyrgyzstan, have lost no ice over the last decade, new research shows.
   The discovery has【C1】______ scientists, who had believed that around 50 billion tons of melted water were being shed each year and not being replaced by new snowfall.
   The study is the first to survey all the world’s icecaps and glaciers and was made 【C2】______ by the use of satellite data. Overall, the【C3】______ of melting ice outside the two largest caps — Greenland and Antarctica — is much【C4】______ than previously estimated, with the lack of【C5】______ loss in the Himalayas and the other high【C6】______ of Asia responsible for most of the discrepancy.
   Bristol University glaciologist Professor Jonathan Bamber said, "The very unexpected result was the【C7】______ mass loss from high mountains of Asia, which is not【C8】______ different from zero."
   The melting of Himalayan glaciers caused【C9】______ in 2009 when a report from the UN’s Intergovernmental Panel on Climate Change mistakenly stated that they would disappear by 2035, instead of 2350.【C10】______, the scientist who led the new work is clear that while greater uncertainty has been discovered in Asia’s highest mountains, the melting of icecaps and glaciers around the world【C11】______ a serious concern.
   "Our results and those of everyone else show we are【C12】______ a huge amount of water into the oceans every year," said Professor John Wahr of the University of Colorado. His team’s study concludes【C13】______ 443 to 629 billion tons of melted water overall are added to the world’s oceans each year. This is【C14】______ sea level by about 1.5 mm a year, the【C15】______ reports, in addition to the 2 mm a year caused by【C16】______ of the warming ocean.
   The scientists are【C17】______to point out that lower-altitude glaciers in the Asian mountain ranges are【C18】______ melting. Satellite images and reports【C19】______ this. But over the study period from 2003 to 2010, enough ice was added to the peaks to 【C20】______. [br] 【C7】
选项 A、susceptible
B、incredible
C、assessable
D、negligible
答案 D
解析 本题考查词义辨析。根据第3段中the lack of ice loss in the Himalayas and the other high peaks of Asia，遵循语义一致性，可推测本句大意为“最出乎意料的结果就是亚洲高山的冰损失量微乎其微”。mass loss意为“质量损失”，此处指“冰损失”。词义辨析：susceptible adj.意为“易受影响的，感情丰富的”；incredible adj.意为“难以置信的”或“极好的，极大地”；assessable adj．意为“可估价的，可评价的，可征收的，可征税的”；negligible adj．意为“微不足道的，可以忽略的”。根据词义选择negligible最为恰当。
