真相大白：

41－45 BGEHC 46-50 KIFAJ

步步为赢：

41.B appeal。the 和 of 之间缺少名词。根据句意：了解周围的环境和我们生活的世界是生态旅游吸引人的地方。故选择appeal。提示：考生应掌握appeal动词和名词的用法；appeal常见的意思还有上诉、呼吁。

42.G marine。这里缺少一个形容词，根据文章下文中讲到的旅行工具airboat和看到的动物alligators (短吻鳄)可以推测生态游可以让我们更好的体验海洋生物（marine life）和自然。

43. E energizing。本空缺少形容词，一场更多学习福罗里达环境的有趣而令人激动的旅行。energizing的意思是“令人振奋的”。

44. H naturalist。本空缺少名词。你会由自然学家带领。

45. C. benefit。考查上下文理解。空中缺少动词，其中有benefit和differ可以与from搭配。differ表示动植物之间的不同，benefit表示动植物之间的互相获益。文中并无对比动植物的区别，而是一再强调生态旅游、保护湿地，故这里应指动植物如何相互获得好处的。

46. K. unspoiled。本题应填入一个形容词，意为“未破坏的自然”。

47. I. preserve。to后面需要使用动词原形，how important it is to preserve the wetland 意思为保护湿地有多么重要。

48. F. fascinated。“that satisfies those”中主语和宾语都不缺， those后面缺少的只能是定语，同时，缺少的词可以与with 搭配的动词。be fascinated with 意思为被……迷住，those 和 fascinate 构成被动关系。故此处选择fascinate的过去分词作定语，修饰those。

49. A. alternative。空格前有“a more exciting and adventurous”说明后面需要一个名词，而Hands-on and active learning on an airboat ride 是 sitting in a classroom之外的另一种选择。考生应注意alternative既可以是形容词，也可以是名词。

50. J. specializing。首先可判断for后面要使用动名词形式，备选选项中只有energizing 和specializing。be reputable for 因……而出名，specialize in doing sth. 专门从事某事。
