    In September, more than a dozen whales beached themselves in the Canary Islands. Rescuers tried to water down the whales and keep them cool. But all of them【C1】________ died.
    Nearby, NATO naval forces were testing echo sounding devices meant to【C2】________ an enemy’s submarines, and public knowledge of the deaths ultimately came to strengthen suspicions of a link between whale distress and loud ocean noises.
    The theory is that the mammals seek to escape the roar of the【C3】________. rush toward the surface and in some cases end up going ashore.
    For decades, environmentalists have worked to reduce the undersea noise—usually with【C4】________ success, given the growing industrialization and militarization of the oceans. They have filed suits and waged letter-writing campaigns, including a recent petition that asks the United States Navy to【C5】________ its testing of underwater sound equipment.
    The discovery by biologists in Hawaii that whales can decrease the sensitivity of their hearing to protect their ears from loud noise【C6】________ another dimension to the debate. Michael Jasny, a senior policy analyst, called the research fascinating and said he hoped it would prove【C7】________ in protecting whale hearing from these threats.
    But he characterized the finding as a work in progress that posed many【C8】________ questions.
    "A lot more work needs to be done," he said. "Could it be replicated in the wild? It’s a huge question." Even if whales could learn to decrease the sensitivity of their hearing, Mr. Jasny said, that would【C9】________ only a relatively small part of the oceanic noise problem. "It’s important to understand that it’s【C10】________." he said of the proposed method. "It won’t be a silver bullet."
【C6】
选项
答案L
解析 本句的主语是the discovery，其后的that whales…noise是主语的同位语从句，故空格处填入的动词应为句子谓语。本段提到的新发现(鲸鱼可以通过降低听觉的敏感性来保护耳朵不受噪音伤害)与上文的“人们更加怀疑鲸鱼遇险与海洋噪音之间的联系”不一致，这会增加讨论，所以答案为adds“添加，增加”。
