Energy is very important in modern life. People use energy to run machines, heat and cool their homes, cook, get light, and transport people and products from place to place. Most energy comes from fossil（化石）fuels--petroleum, coal and natural gas. However, burning fossil fuels cause pollution. Also if we don't find new kinds of energy, we will use up all the fossil fuels in the twenty-first century. Scientists are working hard to find other kinds of energy for the future. What might these sources of energy be?

　　Energy from the wind

　　All over the world, people use the power of the wind. It turns windmills and moves sail-boats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy.

　　Energy from water

　　When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. In Brittany, France, for example, waterpower produces enough energy to light a town of 40000 people. Waterpower gives energy without pollution. However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive.

　　Energy from the earth

　　There is heat in rocks under the earth. Scientists use this heat to make geothermal energy. San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is possible only in a few places in the world.

　　Energy from the sun

　　Solar panels on the roofs of houses can turn energy from the sun into electricity. These panels can create enough energy to heat an entire house. Solar power is clean and there is a lot of it in sunny places. But when the weather is bad, there is no sunlight for energy.

D．Energy changes people's lives.

He was 11 years old and went fishing every chance he got from the dock at his family’s   cabin on an island in the middle of a New Hampshire lake.

　　 On the day before the bass season opened, he and his father were fishing early in the evening, catching sunfish and perch (鲈鱼)  with worms. Then he tied on a small silver lure（鱼饵） and practiced casting. The lure struck the water and caused colored ripples in the sunset, then silver ripples as the moon rose over the lake.

　　When his peapole doubled over, he knew something huge was on the other end. His father watched with admiration as the boy skillfully worked the fish alongside the dock.

　　Finally, he very gingerly lifted the exhausted fish from the water. It was the largest one he had ever seen, but it was a bass. The boy and his father looked at the handsome fish, gills playing back and forth in the moonlight. The father lit a match and looked at his watch. It was 10 P.M.-- two hours before the season opened. He looked at the fish, then at the boy.

　　“You’ll have to put it back, son,” he said.

　　“Dad!” cried the boy.

　　“There will be other fish,” said his father.

　　“Not as big as this one,” cried the boy.

　　He looked around the lake. No other fishermen or boats were anywhere around in the moonlight. He looked again at his father. Even though no one had seen them, nor could anyone ever know what time he caught the fish, the boy could tell by the clarity of his father’s voice that the decision was not negotiable（可协商的）. He slowly worked the hook out of the lip of the huge bass and lowered it into the black water.

　　The creature swished its powerful body and disappeared. The boy suspected that he would never again see such a great fish.

　　That was 34 years ago. Today, the boy is a successful architect in New York City. His father’s cabin is still there on the island in the middle of the lake. He takes his own son and daughters fishing from the same dock.

　　And he was right. He has never again caught such a magnificent fish as the one he landed that night long ago. But he does see that same fish-again and again-every time he comes up against a question of ethics (道德规范).

1. Why did the father ask his son to put the perch back?

2.When does the architect (the father’s son) think of that perch put back?

3.Which word can not be used to describe the boy’s father?
