Li Ming wrote a report about North America.
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.
About 550 million people live in North America. That is a large population, but smaller than that of China. The Great Lakes are the largest bodies of fresh water in the world. The Rocky Mountains are the biggest mountains in North America.
Canada is the biggest of the three countries in area, but it has the smallest population—about 35 million. People speak many languages in Canada. Most speak English or French, but the third most common language is Chinese!
The U. S. is also a very large country, and its population is much larger than any other country in North America. It has a population of more than 315 million. The U. S. is often called America. People in the U. S. are called Americans. Most Americans speak English, and many speak Spanish. Of course, there are a lot of Chinese speakers in the U. S, too—more than 2 million!
Mexico is smaller than both Canada and the U.S. Most of the people there speak Spanish. It has a population of more than 110 million. Mexican people love their country, but many leave to live and work in the U.S. The capital city of Mexico is Mexico City. It is a very big city.
