     Greenland is the largest island in the world. It covers over 2 ,000,000 square kilometers. Most of

the island lies inside the Arctic Circle (北极圈), and a huge sheet (片) of Ice covers 85% of its area.

     Along the sea mountains rise from the sea. There are a few low trees in the southwest, but no forests.

In winter snow covers everything, but in summer very low plants cover the ground between the sea and

the Ice sheet. Norwegians (挪威) were the first Europeans to see the island  in AD 875, but no one

visited it until 982. Three years later a few Norwegians went to live there. In 1261 the people in Greenland decided to join Norway. Norway and Denmark united in 1380. This union ended in 1814, and Greenland

stayed with Denmark. Greenland is fifty times larger than Denmark, but it is still part of this small country.
