答案與解析：
46.C。第三段的第一句話說的是：加勒比群島形成了一條鎖鏈，把加勒比海與大西洋的其他部分分開。有可能構成答案的是C和D。因為它們的第一個詞都是They，該詞指的是The Caribbean Islands。但是，The Caribbean Islands只有古巴等4個國家組成不符合實際情況，因此C是正確的.。
47.B。第四段的第一句話(主題句)說的是：加勒比群島有好幾個名字。這是一個總的概括，緊接著應該是具體的說明。8是具體的說明：歐洲人最早用的名字是印度群島(the Indies)，後來叫作西印度群島(the West Indies)。
48.D。第五段的第一句話說的是：加勒比海有4座大的島嶼。這是一個總的說明。下面應當列舉。D是列舉。
49.F。第六段的第一句話說的是：加勒比群島中的其他島嶼小得多。接著應該是進一步說明。F是進一步說明。
50.E。最後一段講到加勒比海的天氣溫暖，陽光充裕，許多島嶼的海岸有沙灘，這樣的自然環境顯然會吸引旅遊者。故選E。
