Jack was born in a poor family. His father had a small boat and went fishing in the morning and sold the fish in the market in the afternoon. Then he bought some food for his family. When winter came, they were often hungry. One morning the hungry man fell into the river and nobody found him. Jack's mother left her three-year-old son without saying goodbye. His aunt had to look after him.

Twenty years passed. Jack became a tall, strong man. He worked on a farm. He worked hard and wanted to get more money to marry (结婚). He often went to see his aunt with some nice presents. The woman was very happy. But one day she died (死) in a traffic accident (交通事故). The young man was very sad. After he buried (埋葬) her, he decided to buy a beautiful tombstone (墓碑) for her. He went to the town and came into a shop, but all the tombstones were too expensive. He asked, "Do you sell an old tombstone, sir?"

"Yes, we do, sir," answered the shopkeeper.

"Is it as expensive as the new one?"

"No, it is much cheaper," said the man. "But another name was engraved (刻) on it."

"It doesn't matter," said the man. "My aunt could not read."

Our earth is in trouble.  Our drinking water is becoming dirtier, and the air is not as clean as before.  People and factories are polluting the air, rivers and lakes and seas.  You may think that there is mothing you can do to help.  That’s not true.  There are many things you can do to help the earth.

Cars burn gasoline.  This will produce a lot of CO₂ into the air.  Some people believe that too much CO₂ is making the earth warmer than ever.  They think CO₂ thins the clouds above us.  The clouds keep us away from the strongest sunlight.  So try to walk, ride a bike or take a bus.  And if you drive a car, drive at a steady speed.  This can save some gasoline.

The biggest energy use at home is for keeping warm and cool.  So turn the air conditioner off when you don’t need to use it.  Use lights that save energy.

Use fewer things that cannot be used again.  When you buy something, consider those made from things that can be used again first.

（1）要用大量的水来洗澡沐浴。In one week an American family uses as much water for showers as a person drinks in three years! Buy a waterworks that uses less water, or take shorter showers.  This can cut the use of water.
