Which is the biggest country in the world? Well, look at the map and you’ll know it is Russia. It is followed by Canada, China, the U.S.A. and Brazil. Among them, China has the largest number of people, with a population(人口) of about 1.3 billion(十亿). Canada has the longest coastline(海岸线). The total length(长度) of the coastline is about 202,080 kilometers. It is long enough to go around the earth six times.

Do you know which is the largest island(岛) in the world? Is that Hawaii? No, it is much smaller than the largest island in the world—Greenland. Greenland is to the northeast(东北) of Canada. Ice covers 81% of its land. It is very cold there, so there are only about 56,000 people living on the island.
