　　The First Americans

　　There was a time long ago when a land bridge connected Asia and North America．The first settlers in North America crossed this land bridge from what is now Siberia to Alaska．The people who made this initial crossing were probably following the animals they used for food．

　　Eventually, the oceans rose and the land bridge between the continents disappeared．The settlers, who I shall call the "First Americans", could not return to their homeland．　　1　　

　　For the next few thousand years, the First Americans migrated south and east throughout North and South America．They made the journey all the way from Alaska to the southern! tip of South America, a distance of more than 10,000 miles．　　2　　

　　In the far north, above the Arctic Circle, the First Americans became hunters of the ocean．　　3　　 In the brief summer, they gathered berries and other plants．In the winter, they stayed in lodges much of the time preparing for the next summer．It was a hard life, but they learned to survive in these harsh conditions．

　　Farther south, in what is now Arizona, Utah, Colorado, and New Mexico, the First Americans became cliff dwellers(悬崖居民)．They began by living in caves that already existed in the cliffs．　　4　　 The dwellings they constructed in many ways resembled today's apartment buildings．

　　　　5　　 They built a system of dams and canals so they could store and use water almost any time of the year．They were so successful that they could raise fruits and vegetables that were not found naturally in the desert．

　　In Mexico and South America, the First Americans founded civilizations that were among the greatest in the world．They built huge pyramids, lived in fabulous cities, and made great advances in science and mathematics long before the Europeans arrived．

A．They also discovered foods like corn and potatoes．

B．Along the way, they established many different civilizations．

It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.

　　As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.

　　Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .

　　These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.

　　Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.

　　We know a lot about our world, but there are still many answers that we do not have, and we are curious.

According to the passage, which of the following statements is true?

　 A．People are curious in the same way.

　 B．People in different countries are interested in different things.

　 C．Men and women are curious about different things.

　 D．People of different ages are interested in different things

Scientists who work with the biological sciences study____.

A．the earth , the oceans and the sky B．man-made things

C．plants and animals D．ocean water

When you run, your muscles need ____.

A．more nutrition and oxygen B．more signals

C．more salt D．water

A rock cracks _____.

A．in wet regions B．in dry regions

C．at very high or very low temperatures D．when salty water falls in

People are always curious because ____.

A．they cannot explain many things B．they know nothing about the world

C．they know little about the world D．they want to be scientists
