North America is a large continent, but it has only three main countries. Canada is the farthest north. To the south of Canada is the United States. The U.S. is north of Mexico. Together, these three countries cover about 24 million square kilometres.

The main thing is to stay calm.

最重要的是要保持冷静。

2. To the south of Canada is the United States.
