7．Whether we should allow marine （海洋的） parks to stay open has been widely debated in our community recently．A variety of different arguments have been put forward about it．
Smith，a sociologist，argued that dolphin parks provide the only opportunity for much of the public to see marine mammals．As this argument goes，most Australians live in cities and never get to see these animals．Marine parks allow the average Australian to appreciate our marine wildlife．However，in fact，there are many places where they can be seen in the wild．Moreover，these places do not charge an overpriced entry fee-they are free．
Dr．Alison Lane，the director of the Cairns Marine Science Institute，insists that we need marine parks for scientific research．She argues that much of our knowledge of marine mammals comes from studies which were undertaken at marine parks．The knowledge which is obtained at marine parks can be useful for planning for the preservation of marine mammal species．However，Jones，a zoologist，explains that park research is only useful for understanding captive animals and is not useful for learning about animals in the wild．Their diets are different，they have significantly lower life lengths and they are more likely to have a disease．In addition，marine mammals in dolphin parks are trained and this means that their patterns of social behaviour are changed．
The Marine Park Owners Association holds that marine parks attract a lot of foreign tourists．This position goes on to state that these tourists spend a lot of money，increasing our foreign exchange earnings and assisting our national balance of payments．However，foreign tourists would still come to Australia if the parks were closed down．Indeed，surveys of overseas tourists show that they come here for a variety of other reasons and not to visit places like Seaworld．Tourists come here to see our native wildlife in its natural environment and not to see it in cages and concrete pools．They can see animals in those conditions in their own countries．
In a word，perhaps an agreement cannot be reached now．However，a question does deserve our consideration：If we continue with our past crimes against these creatures，how will our future generations view us？

分析 本文属于说明文阅读，这篇文章是关于是否保留海洋公园的争论，不同的人有不同的观点，赞同的人认为海洋公园有娱乐，科学研究和改善经济的功能，而不赞同的认为这些科学研究是有局限性的，而且即使没有海洋公园，游客也会来游玩，因此人们不能得出一致的结论．
解答 67．D 细节理解题：根据文章第三段的句子：However，Jones，a zoologist，explains that park research is only useful for understanding captive animals and is not useful for learning about animals in the wild．可知Jones认为海洋公园不适合研究野外动物，因此他是支持关闭海洋公园的想法，故选D．
68．B 细节理解题：根据文章第三段的句子：However，Jones，a zoologist，explains that park research is only useful for understanding captive animals and is not useful for learning about animals in the wild可知作者想要告诉我们在海洋公园的科学研究有它自己的限制，故选B．
69．D 细节理解题：根据文章第三段的句子：Dr．Alison Lane，the director of the Cairns Marine Science Institute，insists that we need marine parks for scientific research．以及文章第四段的句子：The Marine Park Owners Association holds that marine parks attract a lot of foreign tourists．This position goes on to state that these tourists spend a lot of money，increasing our foreign exchange earnings and assisting our national balance of payments．可知保留海洋公园的原因有三条：娱乐功能，科学研究，经济目的，但是文章没有提到有政治目的，故选D．
70．A 细节理解题：根据文章最后一段的句子：，a question does deserve our consideration：If we continue with our past crimes against these creatures，how will our future generations view us？可知作者想说服读者接受这种论点主要是通过指出保留海洋公园的问题，故选A．
点评 考查学生的细节理解和推理判断能力．做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确选择．在做推理判断题时不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
