7．In October on the east coast of Australia migrating（迁徙）humpback whales（座头鲸）pass very close to the shore．With the help of Max Egan，we went to film them near Byron Bay．It was extremely exciting to spot the little puffs（水柱）of spray on the horizon．When migrating，the whales can be traveling at speeds of about 12km/h and can dive under anywhere between five and forty minutes．but with many years of experience Max usually guided our boat to exactly the right place to provide us with amazing sighting．As the whales break the surface like submarines（潜水艇），the water spills off their broad dark backs and huge tails．Then，with a powerful down stroke，they dive back into the depths of the sea，leaving just a smooth glassy patch of water or"footprint"on the surface to show where they had been．
One day we had traveled up and down the shore and far out to the sea in search of whales，but the horizon was deserted．There was no report of whales in the area so we decided to test out Max's new，highly sensitive hydrophone（水中听音器）and the result was astonishing．As soon as the hydrophone was in the water，we found ourselves listening to the most beautiful voices．What may have seemed like a vast empty ocean was filled with the singing of whales．
It is the males which sing，as they migrate between feeding and breeding（养育）grounds．No one knows for sure what the purpose of these songs is，whether they are love songs to the females or warnings to other males to stay away．
It was thought that each population of humpbacks had its own song which remained regular but recent findings suggest that the whales appreciate a memorable tune（曲调）and quickly adopt any new songs they hear．
29．Which finding about whales is beyond the writer's expectation？B．
A．The little puffs．

分析 本文是一篇社会文化类阅读，10月份澳大利亚东海岸的座头鲸通过迁移非常接近海岸，在马克斯•伊根的帮助下，我们去拍了电影靠近拜伦海岸，这是非常令人兴奋的，发现喷在地平线上的小水柱．本文以此展开，主要讲述了作者有关座头鲸歌声的一些发现．
解答 29．B．细节理解题．根据There was no report of whales in the area so we decided to test out Max's new，highly sensitive hydrophone（水中听音器）and the result was astonishing．以及下文可知，有关鲸鱼歌声的发现令作者很惊讶．故选B．
30．C．推理判断题．根据With the help of Max Egan，we went to film them near Byron Bay．以及There was no report of whales in the area so we decided to test out Max's new等可以推测出，他是一位有经验的人在寻找鲸鱼方面．故答案选C．
31．C．细节理解题．根据With the help of Max Egan，we went to film them near Byron Bay．可知，作者寻找鲸鱼的原因是拍摄有关鲸鱼的电影．故选C．
32．A．细节理解题．根据It was thought that each population of humpbacks had its own song which remained regular but recent findings suggest that the whales appreciate a memorable tune（曲调）and quickly adopt any new songs they hear．可知，据说每一群座头鲸都有它自己的歌仍然定期，但最近的研究表明，鲸鱼欣赏一个难忘的曲调，并迅速采取任何他们听到的新歌．故A项错误．故选A．
