雷庆国回答：

　　1.A2.C3.B4.A5.D 　　分析：　　本文介绍了海洋里的动物正在受人类引起的噪音的威胁。科学家计划制定在海洋噪音的限制为120分贝以下，许多科学家认为这个分贝的限制将意味着结束重要的工业和科学研究，然而他们怀疑噪音的影响远比他们认为的要危险。因此他们想要阻止噪音伤害海洋里的生物。1.2.概括归纳题。根据Decibels(分贝)measuredinwateraredifferentfromthosemeasured（测量）onland.可知第二段主要介绍了同一种噪音在水里的测量和在陆地上不同。故选C。3.细节理解题。根据Theyhavefoundthatnoisesatthatlevelcanfrightenandconfuse(混淆)whales.可知某种程度上的噪音可能让鲸鱼害怕和混淆，使鲸鱼受伤。故选B。4.细节理解题。根据Theysaysuchalimitwouldmeananendtoimportantindustrial（工业的）andscientificresearch.可知许多科学家认为这个分贝的限制将意味着结束重要的工业和科学研究，故选A。5.推理判断题。根据Theywanttostopnoisesfromharmingcreaturesintheocean.可知科学家们想要阻止噪音伤害海洋里的生物。故推断在将来他们将保护海洋里的动物不受噪音的伤害。故选D。　　考点：　　环保类短文阅读。
