答案解析
46 c 第三段的第一句話說(shuō)的是：加勒比群島形成了一個(gè)鎖鏈，把加勒比海與大西洋的其他部分分開(kāi)。有可能構(gòu)成答案的是c和D.因?yàn)樗鼈兊牡谝粋�(gè)詞都是“They”，該詞回指“The Caribbean Islands”。但是，“The Caribbean Islands”只有古巴等四個(gè)國(guó)家組成不符合實(shí)際情況，因此c是正確的。
47 B 第四段的第一句話(主題句)說(shuō)的是：加勒比群島有好幾個(gè)名字。這是總的概括，緊接著應(yīng)該是具體的說(shuō)明。B是具體的說(shuō)明：歐洲人最早用的名字是印度群島(the Indies)，后來(lái)叫做西印度群島(the West Indies)。
48 D 第五段的第一句話說(shuō)的是下面應(yīng)當(dāng)列舉。D是列舉。
49 F 第六段的第一句話說(shuō)的是一步說(shuō)明。F是進(jìn)一步說(shuō)明。加勒比海有四個(gè)大的島嶼。這是一個(gè)總的說(shuō)明。加勒比群島中的其他島嶼小得多。
50 E 最后一段講到加勒比海的天氣溫暖，陽(yáng)光充裕，許多島嶼的海岸有沙灘。這樣的自然環(huán)境顯然會(huì)吸引旅游者。因此E是正確的選擇。
