A science book gives facts. Some science books tell us about animals. Some tell us about plants. Some tell us about outer space. This page tells us about animals.

Do you know that not only the fish but also some animals live in the sea? For example, the whale is not a fish. It can’t breathe in the water. It swims in the water. But it comes up for air.

The blue whale is the world’s biggest animal. There are other sea animals, too. One is called the dolphin. Dolphins need air to live. They breathe air, as whales do. Dolphins are very clever. They sometimes seem to speak to each other.

Many other animals live near the sea. Seals（海豹）and otters（水獭）love the sea. They swim and play there. They eat fish and sea plants. Seals and otters have thick fur. The fur keeps them warm.

The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.

To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威胁) our health, our happiness and our life.

Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren’t so many people then and their wants fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over. But this is no longer true. The increase of pollution and the development of industry(工业) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.

Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.

Our increasing population is part of the problem. More people, more waste.

Where is this all to end? Are we turning the world into a big rubbish dump(堆存处)，or is there any hope that we can get rid of (摆脱，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.

The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.

There was once a young mouse that lived in a hole in a wall. One day, the young mouse woke up from his sleep and looked out of the hole. As he looked out, a fantastic smell came to his nose. “Cheese!” the mouse said happily to himself. “I’ll go and get it now and have it for breakfast.”

But then he remembered his parents’ words. His parents were very clever mice and often said to their son, “Always wait before you go for a piece of cheese.”

So the young mouse waited quietly. Then he heard a quiet “Miaow” and he knew the cat was there. He stayed in the hole and said to himself, “I’m glad I listened to my parents and learned to wait.”

The next day, he looked out again. He put his nose out of the hole, and the beautiful smell of cheese came to his nose again. He could see the cheese. It was only a few centimetres away. But he sat still and waited quietly. This time he did not hear any cat’s noise. Instead he heard a very quiet “Woof, woof.”

“It’s a dog!” he thought. “If the dog is there, the cat won’t be there. I expect the dog has chased the cat away, so I’m safe.” The mouse ran out of the hole and started eating the cheese. He did not see the cat, which caught him and ate him.

When the cat finished her meal, she said to herself, “I’m glad I listened to my parents and learned a second language.”
