    Water has no colour, no shape, no taste and no smell. Water is everywhere. It is in the ocean, in the sea, in the river and in the lake. Water is (use). We use water to cook rice. We use water to take showers. We use water to put out fires. We can swim the lake and the sea. People in China have Dragon Boat Race in the river.

    Water is (value). It brings us happiness. Nothing can live without it. some people waste water and pollute water every day. They keep (throw)rubbish into rivers and lakes. Many (factory)even put waste water into rivers. Let's do (we)best to save water keep the water clean. Don't forget (turn)off the tap after you wash hands. Don't throw rubbish into rivers and lakes.

    When you hear the word "scientist", what do you think of it? Many people think scientists are people in clean white coats, working in labs( 实验室). Some scientists do work in labs. But there are 1 scientists working in woods and jungles(丛林).  These scientists are called " animal behaviour (行为) scientists", and they study animals as they live in nature. Why don't these scientists catch animals and study them in zoos? The 2 is in the word "behaviour". Animal behaviour scientists want to learn 3 animals behave in their wild homes. When animals live in cages or in zoos, they do not act 4 as they do in the wild. They may fight (打架) 5each other, or they may not eat, or they may not raise (抚养) their babies as they usually do. To see real animal behaviour, scientists must go to the places 6the animals live. So animal behavior scientists go into the jungles, the woods or the deserts. There, 7most important tools are their eyes and ears. They watch and listen to the animals very 8. They write down everything that happened in notebooks. Though they live near the animals, the scientists are careful not to frighten them. If the scientists are 9, the animals will pay no attention to them. Then the scientists can see how the animals really live.

    The animal behaviour scientists hope what they've learned about animal behaviour can provide clues(提供线索) 10people learn to live with animals together more happily.

    Why do plants grow in some places and not in others? Why does some land have so many plants growing on it, while other land has almost（几乎）no plants growing on it at all?

    To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That's why dry deserts(沙漠）everywhere are almost not covered by trees or grass.

    Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones to grow in.

    Another thing plants must have before they can grow is food.

    What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won't. Even if(即使）the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.

    There is little rain in deserts. Because deserts are so dry, they have no"quilt" to help stop the soil from going away. As a result, they may get very hot during the day with the Sun shining, but don't hold the heat overnight. Many deserts can quickly get cold once the Sun goes down. Some deserts can reach the temperature of over 100 degrees F during the day and then drop below freezing(32 degrees F)during the night.

    The largest hot and dry desert in the world is the Sahara Desert in North Africa. The Sahara is a sandy desert with great sand hills. It covers over 3 million square miles of Africa. Other large deserts include the Arabian Desert in Western Asia, the Gobi Desert in northern China and southern Mongolia, and the Kalahari Desert in Africa.

    Animals that live in the desert are also used to needing little water. Many get all the water they need from the food they eat. Other animals keep water that they can use later. The camel stores up fat in its hump while other animals keep something they need in their tails.

    Only certain types of plants can live in the terrible environment of the desert. You won't see a lot of tall trees in the desert. Most plants have a way to keep water in their leaves or trunks so they can live a long time without water.

    Now deserts cover around 20% of the world's land, but they are growing. This is called desertification and is caused by different reasons including human activities. The Sahara Desert is growing larger and larger each year. What should we do with it?

    Alan worked in an office in the city. He worked very hard and really looked forward to his holiday. He usually went to the seaside, but one year he saw an ad in a newspaper Enjoy country life. Spend a few weeks at William Farm. Good food, fresh air, horse riding, walking, fishing.

    "This sounds like a good idea," he thought, "I'll spend a month at William Farm. I'll go horse riding, walking and fishing. It'll be different from the seaside." Four days later, he returned home.

    "What's wrong with William Farm?" his friend Jack asked him. "Didn't you enjoy country life?"

    "Country life was fine, "Alan said." But there was another problem."

    "Oh, what problem?"

    "Well, the first day I was there, a sheep died, and we had roast（烤好的）mutton for dinner. "

    "Fresh meat is the best."

    "I know, but on the second day a cow died, and we had roast beef for dinner."

    "Lucky you!"

    "You don't understand, "Alan said." On the third day a pig died and we had roast pork for dinner. "

    "A different roast every day, "Jack said.

    "Let me finish, "Alan said." On the fourth day a farmer died and I didn't want to stay there for dinner. "

    Mr White was over 80 years old, but he looked younger than his age. He played Tai Chi in the park every day, so he was very healthy. It was 11:30. It was time for him to walk home. He usually got home thirty minutes later. One day, Mr White didn't get home when it was 12：30. His family worried about him. After a short while, a police car stopped in front of their house. What happened?

    "The old man was lost and he called us for help," the policeman said.

    When the policeman left, Mr White's daughter asked her father, "Dad, you go to the park every day. How can you be lost?" "I'm not lost at all. I'm just tired. I don't want to go home on foot," answered Mr White with a smile.
