Passage 1 The United States covers a large part of the North American continent. Its neighbors are Canada to the north and Mexico to the south. Although the United States is a big country, it is not the largest in the world. In 2000, its population was over 222 million. When this land first became a nation, after winning its independence from England, it had thirteen states. Each of the states was represented on the American flag by a star. All these states were in the eastern part of the continent. As the nation grew toward the west, new states were added and new stars appeared on the flag. For a long time, there were 48 stars. In 1959, however, two more stars were added to the flag, representing the new states of Alaska and Hawaii. Passage 1 The United States covers a large part of the North American continent.

There are still many thousands of Indians now living in all parts of the country. Sometimes it is said that the Indians are“the only real Americans”. Most Americans come from all over the world. Those who came first in greatest numbers to make their homes on the eastern coast of North America were mostly from England.It is for that reason that the language of the United States is English and that its culture and customs are more like those of England than those of any other country in the world.This story teaches us two lessons: 1. There is power of life and death in the tongue. An encouraging word to someone who is down can lift him up and help him make it through the day. 2. A destructive word to someone who is down can be what it takes to kill him. Be careful of what you say. The power of words is sometimes hard to understand because an encouraging word can go such a long way. Anyone can speak words that tend to rob another of the spirit to continue in difficult times. Special is the individual who will take the time to encourage another. 6. Which of the following is TRUE? A.America is the largest country in the world. B.The United States lies next toCanada and Mexico. C.America covers most part of the North American continent. D.Mexico is to the north of Canada. 7.

Why is English the language of America? A.Because English is the native language of the Indians. B.Because most Americans come from all over the world. C.Because Canada is America’s nearest neighbor.
