第2题
The original Americans, of course were the Indians.The so-called white men who then came were mostly from England.But many came from other countries like Germany and France.
One problem the United States has always had is discrimination.As new groups came to the United States, they found they were discriminated against.First it was the Irish and Italians.Later it was the blacks.Almost every group has been able to finally escape this discrimination.The only immigrants who have not are the blacks.Surprisingly enough the worst discrimination today is shown towards the Indians.
One reason the Indians are discriminated against is that they have tried so hard to keep their identity.Of course they are not the only ones who have done so.The Japanese have their Little Tokyo in Los Angeles and the Chinese a Chinatown in New York.The Dutchsettlement in Pennsylvania also stays separate from other people.Their towns are like something from the 19th century, They have a different reason from the other groups for staying separately.They live separately for religious reasons rather than keep together in a racial group.
Although some groups have kept themselves separate and others have been discriminated against, all groups have helped make the United States a great country.There is no group that has not helped in some way.And there is no group that can say they have done the most to make it a great country.
Many people still come from other countries to help the United States grow.A good example is the American project that let a man walk on the moon.It was a scientist from Germany who was most responsible for doing that.It is certain that in the future the United States will still need the help of people from all racial groups to remain a great country.

听力原文： Human beings enjoy challenges. Many of them like physical challenges. They ask themselves questions like these: How fast can I run ？ How high can I climb？ How deep can I dive？ How far can I swim？ How long can I hold my breath？ How much can I lift？ How high can I jump？ Because people enjoy challenges, they like to play sports and watch other people play sports. They like climbing, running, diving, lifting, jumping, and so on. Every four years millions of people all over the world enjoy the international sports competitions called the Olympics.
There are challenges that are not physical challenges. There are social and intellectual challenges, too. Leonardo Da Vinci, who lived in Italy during the fifteenth century, enjoyed every possible challenge. He was an artist and painted the well-known picture, the Mona Lisa. He was an inventor who invented a device to let people breathe under water. He was a scientist, and he learned a great deal about human anatomy.
Another kind of challenge faced the Egyptians between 4,000 and 5,000 years ago when they decided to build the first pyramid. They used six million tons of rock. That is enough to build a ten-foot wall around all of France. Four hundred thousand men worked for twenty years to build it.
So, for thousands of years, people accept challenges. Today we still have many challenges before us. Medical science faces the challenges of conquering the many diseases which still attack human beings. Engineers and planners must build new cities and new kinds of transportation. Scientists must develop new forms of energy. And many of us are interested in the challenge of space. We live in an age of challenge.

C．Physical challenge.
D．Economic challenge.

The scientist's knowledge must be exact.There is no room for half right or right just half the time.He must be as nearly right as the conditions permit.What works under one set of conditions at one time must work under the same conditions at other times.If the conditions are different,any changes the scientist observes in a demonstration must be explained by the changes in the conditions.This is one reason that investigations are important in science.Albert Einstein,who developed the theory of relativity,arrived at this theory through mathematics.The accuracy of this mathematics was later tested through investigations,Einstein's ideas were shown to be correct.A scientist uses many tools for measurements.Then the measurements are used to make mathematical calculations that may test his investigations.
