Do you know where Greenland is? It's the largest island on Earth. It lies in the north of Europe. 1 Its name is Iceland. Do you think that Greenland is green and warm? Do you think that Iceland is white with ice? 2 Not many people live on the big island of Greenland. There are more people in your hometown than in all of Greenland. That is because Greenland is not green. Greenland is white. 3 The ice covering Greenland is higher than some of the world's buildings. What about Iceland? 4 No, it is not. Iceland has ice, but not so much ice as Greenland. Iceland has a lot of hot springs. They give out hot water and steam. 5 And it has a much larger population.

【解析】：我们可以根据上下文的逻辑衔接来逐一确定答案：
1. 空1后句子提到“它的名字是冰岛”，说明此处是引出除格陵兰之外的另一个岛屿，对应选项B。
2. 空2前提出了两个大众对格陵兰和冰岛的常见错误猜想，后文开始介绍真实情况，说明这些猜想是错的，对应选项D。
3. 空3前说明格陵兰是白色的，空3后描述格陵兰上的冰层高度，此处衔接介绍格陵兰大部分区域被冰覆盖，对应选项C。
4. 空4后用“No, it is not.”回答，且后文说明冰岛的冰没有格陵兰多，可知此处的问题是询问冰岛是否比格陵兰更冷，对应选项A。
5. 空5前提到冰岛有很多温泉，会释放热水和蒸汽，这一现象带来的结果就是冰岛不像格陵兰那么寒冷，衔接后文冰岛人口更多的内容，对应选项F。
