7．In October on the east coast of Australia migrating（遷徙）humpback whales（座頭鯨）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（潛水艇），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（水中聽音器）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（養(yǎng)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（曲調(diào)）and quickly adopt any new songs they hear．

分析 本文是一篇社會文化類閱讀，10月份澳大利亞東海岸的座頭鯨通過遷移非常接近海岸，在馬克斯•伊根的幫助下，我們?nèi)ヅ牧穗娪翱拷輦惡０�，這是非常令人興奮的，發(fā)現(xiàn)噴在地平線上的小水柱．本文以此展開，主要講述了作者有關(guān)座頭鯨歌聲的一些發(fā)現(xiàn)．
解答 29．B．細(xì)節(jié)理解題．根據(jù)There was no report of whales in the area so we decided to test out Max's new，highly sensitive hydrophone（水中聽音器）and the result was astonishing．以及下文可知，有關(guān)鯨魚歌聲的發(fā)現(xiàn)令作者很驚訝．故選B．
30．C．推理判斷題．根據(jù)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等可以推測出，他是一位有經(jīng)驗的人在尋找鯨魚方面．故答案選C．
31．C．細(xì)節(jié)理解題．根據(jù)With the help of Max Egan，we went to film them near Byron Bay．可知，作者尋找鯨魚的原因是拍攝有關(guān)鯨魚的電影．故選C．
32．A．細(xì)節(jié)理解題．根據(jù)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（曲調(diào)）and quickly adopt any new songs they hear．可知，據(jù)說每一群座頭鯨都有它自己的歌仍然定期，但最近的研究表明，鯨魚欣賞一個難忘的曲調(diào)，并迅速采取任何他們聽到的新歌．故A項錯誤．故選A．
點評 本文是一篇社會文化類閱讀，題目涉及多道細(xì)節(jié)理解題，推理判斷題．做題時學(xué)生應(yīng)仔細(xì)閱讀原文，把握文章主要內(nèi)容，聯(lián)系文章上下文內(nèi)容并結(jié)合所給選項含義，從中選出正確答案，一定要做到有理有據(jù)，切忌胡亂猜測．
