Greenland is the largest island(岛)in the world. It’s in Europe(欧洲). Near Greenland there is another land. It’s very small. Its name is Iceland. Do you think Greenland is green and warm? And do you think Iceland is white with ice? If you do, you are quite wrong. Few people live on Greenland. Maybe there are more people in one small town on Iceland than those in the whole of Greenland. Because most of the island is covered with(覆盖)ice, the ice on Greenland is higher than the tallest building in the world. How about Iceland? Is it colder than Greenland? No, it isn’t. Iceland has ice, but not so much ice as Greenland. Iceland has lots of hot springs. They give out hot water and steam(水蒸气). The weather is not so cold as that on Greenland. And there are more people on Iceland than on Greenland.

根据短文内容,判断正(A)误(B)。(10分)
