Thousands of years before Columbus came to the New World, the American Indians entered Nor

Thousands of years before Columbus came to the New World, the American Indians entered North America by crossing a narrow strip of land that once connected Alaska and Siberia. The migrants entered a new world in which there were no people at all. But there were many animals to hunt, and there were forests where nuts, roots and berries could be gathered.

(27) When the Europeans came to the New World, the Indians, at first, taught the settlers how to plant corn, bake fish, make canoes and smoke tobacco. In return, the whites introduced horses, guns, gun-powder and alcohol. But at last, there were struggles for land, and the struggles could have only one result-war. When the wars were over, all Indians were moved to large tracts of land called reservations. Now, some of them, embittered by past mistreatment, are determined to preserve their tribal life; some wish to modernize the reservations. These alternatives, with many variations, are what most Indians have chosen-a future in modern technology and education, or the revival of ancient tradition and treaties.

The Indians entered North America______.

A．with Columbus

B．before Columbus did

C．after Columbus' arrival

D．in the 18th century

When Christopher Columbus" discovered" the New World in 1492, he thought he had reached the continent of Asia and had landed in India. He called the people he found in this new land "Indians" -the ancestors of the American.

Indians had come from Asia thousands of years before Columbus saw them.

Thousands of years ago, the Earth was in an ice age. (76) People who lived in northeastern Asia found their homeland growing colder. Huge sheets of ice were spreading over the land and animals people hunted for food were being forced away. The people also had to move, to stay near the animals. Some groups of people crossed Bering Strait from Asia to North Pacific Ocean, which separates northeastern Asia from Alaska. (77) These people slowly traveled east and south, searching for areas where hunting was good. Their children and all those who came after them continued to spread throughout the New World.

The Indians do not have yellowish skin that many Asian people have. Their skin is reddish brown. But like the people of Japan and other countries of Asia, Indians usually have high cheekbones and straight black hair.

In 1492, Christopher Columbus ______.

A．found American Indians in Asia

B．thought he had reached India

C．landed in India

D．reached the continent of Asia

Thousands of years ago, traveling was very hard. There were no roads and no cars. People traveled on rivers and lakes. They used logs, either one at a time, or tied together.

People then began to use animals to pull very heavy loads. Some people put rollers under a load, and this was the first use of the wheel. The wheel was the most important invention in transportation.

The need to transport many people at one time led to the use of the stagecoach. It's a horse-drawn public vehicle carrying passengers along a regular route. The stagecoach was pulled by four to six horses. It often rode through the night with a change of a driver.

But people wanted a faster and easier way of traveling. The "horseless carriage" of automobile was invented in 1892. Life became more pleasant. Roads were built. Farmers were able to travel to cities. City people were able to get fresh fruits and vegetables. People traveled to many places for fun.

The main idea of the first paragraph is that ______.

A．people traveled on lakes thousands of years ago

B．people used logs thousands of years ago

C．traveling was hard thousands of years ago

D．there were no roads and cars thousands of years ago

Thousands of years ago, ten of our very distant ancestors were hungry. They went out and picked berries or dug up roots to eat. Four of them chose poisonous food and died. The remaining six noticed that their food was safe to eat. They told their children, who, in turn, passed the message on to their descendants. In this way, habit became a vital factor in the survival of mankind : if you ate the right plant, you lived; if you wanted to make your own experiments, you would probably die.

The importance of habit on the survival of the human species is an interesting matter. Even today, most of us hesitate when we are invited to eat a new type of food or drink something we have not tasted before. Even if the food or drink is offered by a friend, we are usually not at all anxious to experiment and accept the offer.

When you get up tomorrow morning, notice which shoe or sock you put on first. Then notice which one you put on first on other days. You may discover that (a) you tend to put on one shoe or sock first every day, and that (b) if you are right-handed, you usually deal with your left shoe or sock first. If you try to change this habit, you may find it uncomfortable or annoying, and you will soon return to your old habit.

When it comes to other matters, we often follow a fixed pattern. We sleep in one or two favorite ways. We often follow familiar routes even when they are not the shortest or best. We often wear a watch on the same wrist even when there is no real reason for doing so. (83)In hundreds of other ways, we show that we are creatures of habit, following fixed patterns of behavior. This characteristic can help us to survive but it can be a barrier to progress too. We must be alert and not let a beneficial factor become a harmful one.

The best title for this passage might be _____.

A．Habit—a Barrier to Progress

B．The Survival of Mankind

C．Various Patterns of Human Behavior

D．We Are Creatures of Habit

The United States has more than one hundred twenty medical colleges. The American Association of Medical Colleges says these schools have about seventy thousand students.

How hard is it to get into one of the top medical schools, like for example the one at Yale University in Connecticut? Last year almost three thousand seven hundred students hoped to get accepted there. Only one hundred seventy-six -- or less than five percent -- were admitted.

People who want to become medical doctors often study large amounts of biology, chemistry and other science. Some students work for a year or two in a medical or research job before they try to get accepted to medical school.

Medical students spend their first two years in classroom study. They learn about the body and all of its systems. And they begin studying diseases -- how to recognize and treat them. By the third year, students guided by experienced doctors begin working with patients in hospitals. As the students watch and learn, they think about the kind of medicine they would like to practice as doctors. During the fourth year, students begin applying to hospital programs for the additional training they will need after medical school. Competition for a residency at a top hospital can be fierce.

A medical education can be very costly, especially at a private school. One year at a private medical college can cost forty thousand dollars or more. The average at a public medical school is more than fifteen thousand dollars. Most students have to take out loans to pay for medical school. Many finish their education heavily in debt.

Doctors are among the highest paid professionals in the United States. Specialists in big cities are generally the highest paid. But there are also doctors who earn considerably less, including those in poor communities.
