Ladies and gentlemen, I returned to this year in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth. This year is your last chance your lifestyle to save the earth.

  Beginning in the middle of the 20^th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour(倒) dangerous chemical(化学物品) and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.

  By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids(液体). Scientists said that in the future there might be too many people on the earth. But not enough was done.

  So by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in lakes and seas died because of pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.

  By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.

  So it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.

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.

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.

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

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

All living things on the earth need other living things to live with. Nothing lives  1 . Sometimes one living thing kills    2  . Each kind of life eats another kind of life     3   live, and together they form a food chain(食物链). Some food chains are simple, while others are not. But    4    food chains begin with the sun, and all food chains become    5   if one of the links disappears.

All life needs sunlight to live on. But only plants can use    6   directly(直接地). They make food from sunlight, water, air and so on. Animals can only use the sun’s energy    7    it has been changed into food by plants. Some animals feed directly on plants. Others eat smaller animals. Meat-eating animals are only   8 plants indirectly.

What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruits and so on. We also eat meat and drink milk. But   9     often break up the food chains. They kill wild animals. They also make rivers, lakes and seas dirty. When these rivers, lakes and seas are polluted, the fish in them    10   be eaten. If people eat the fish, they will get strange diseases.

Each form of life is linked to all the others. Breaking the links puts all life in danger.
