                        Canada Is Our Neighbour

    Canada and the United States are neighbours. They are on

the same land.  They share the same long boundary(国界) . These

two nations are same in many ways.  Canada buys many goods from

the United States.  Cars and clothes are two examples. The United

States also buys goods from Canada. Much of the paper used in

the United States comes from Canada. Some of the oil we use

comes from Canada, too.

       Americans travel to Canada on holiday.  And Canadians often

visit the United States. It is easy for the people of one country to

go to the other country.

    Canadians read about the United States in newspapers and

magazines. Many Americans watch Canadian baseball and hockey

(曲棍球) matches on Sundays.

     However, there are important differences between the United

States and Canada. The United States has many more people.

   Because the population is smaller, there are more open

places in Canada. There is much unused land. This is another

important difference.
