答案解析

46 C 第三段的第一句话说的是：加勒比群岛形成了一个锁链，把加勒比海与大西洋的其他部分分开。有可能构成答案的是C和D。因为它们的第一个词分别是others，，和“They”，该词回指“The Caribbean Islands”。但是，“The Caribbean Islands”只有古巴等四个国家组成不符合实际情况，因此C是正确的。

47 B 第四段的第一句话(主题句)说的是：加勒比群岛有好几个名字。这是一个总的概括，紧接着应该是具体的说明。B是具体的说明：欧洲人最早用的名字是印度群岛(the Indies)，后来叫做西印度群岛(the West Indies)。

48 D 第五段的第一句话说的是：加勒比海有四个大的岛屿。这是一个总的说明。下面应当列举。D是列举。

49 F 第六段的第一句话说的是：加勒比群岛中的其他岛屿小得多。接着应该是进一步说明。F是进一步说明。

50 E 最后一段讲到加勒比海的天气温暖，阳光充裕，许多岛屿的海岸有沙滩。这样的自然环境显然会吸引旅游者。因此E是正确的选择。
