1.______2.______3.______4.______5.______

答案： 1. C　细节句。第一段介绍了大沼泽地国家公园的特点。根据空后的“It is also the third largest national park in the lower forty - eight states, after Death Valley and Yellowstone.”可知此处在介绍大沼泽地国家公园，结合该句中的also可推断出空处也是在介绍这个公园，C项（这个公园是几种稀有和濒危物种的家园）属于对该公园的介绍，符合语境。故选C。
易错归因
虽然E项和F项也是在介绍大沼泽地国家公园的情况，但是第一段最后一句和E项意义相近，语意重复，由此可排除E项，而在看了第二段（介绍生物的多样性）之后可知F项是第二段的主题句，由此可排除F项。
2. F　主旨句。空处位于段首，为该段主旨句。根据下文可知大沼泽地国家公园面积广阔，在这里，来自加勒比海的动植物与北美洲本土物种共享一个生态系统。F项（大沼泽地国家公园被认为是世界上伟大的生物奇迹之一）符合语境，与本段介绍的生物多样性一致。故选F。
3. G　细节句。根据上文“The Everglades is home to about fifteen species that federal officials say are threatened or endangered.”可知，G项（它们包括佛罗里达美洲狮、美洲鳄和西印度海牛）符合语境，承接上文，是对上文濒危物种的举例。故选G
4. B　主旨句。空处位于段首，为该段主旨句。根据本段中的“the largest growth of mangrove trees”“Gumbo - limbo trees”“strangler figs and royal palms”等内容可知，本段介绍大沼泽地国家公园的奇异植物。B项（到大沼泽地国家公园的游客会看到许多奇异的植物）符合本段主旨。故选B。
5. A　过渡句。根据上文“They say the balance of nature there has been destroyed.”以及下文“However, efforts to protect the area are continuing so people from all over the world may continue visiting this biological treasure.”可知，A项（大沼泽地国家公园的未来还不清楚）符合语境，承接上文对大沼泽地国家公园现状的介绍，说明其未来的未知性，且与下文构成转折关系，说明虽然其遭到破坏，但人们正在采取保护措施。故选A。
