Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the rivers, or on the grassland, you should know that your sport of choice might have great influence on the environment.
② Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all kinds of harmful things and a lot of energy are used to keep its courses(球场)，This leads to serious environmental problems. For example, in Portugal and Spain, golf is considered to be the most important reason for water shortage(短缺）io some areas.
③ There are many environment-friendly sports. Power walking is one of them that you could do today. You don't need anything special but a good pair of shoes; and you don't have to worry about nature and your money. Simple and free, power walking -can also keep you fit. If you often walk, it will be good for your heart and bones.
④Nowadays more and more people choose to play "green sports". They play sports outdoors, in the countryside or other open spaces. There is no special things needed. And best of all, it's free.

    Last month some thieves stole a valuable teapot from a museum in Hong Kong. They took the teapot to America, but the American police found it. The museum sent Mr. Chan, a member of the museum staff, to collect the teapot. On the plane back to Hong Kong, he noticed two men. They were watching him closely. "Perhaps they're going to steal the teapot again. I must think of a plan,” he thought.

    Mr Chan's daughter, Amy, met him at Hong Kong Afimor. Mr Chan NS was carrying two boxes. He gave his daughter the pink box and said to her in a low voice, "Take this gift box home with great care." He walked away with the brown one. The two men followed him.

    Amy opened the box at home. She was expecting a pair of sports shoes, but she just found an old teapot. "This is not a very interesting gift," said Amy, a bit disappointed." That's all right. Let's make some tea in it," said her mother. Then they found a note in the teapot. It said, "Dear Amy, __ Love Dad.”

    The two men kidnapped(绑架)Mr. Chan on his way to the museum. They opened his box and found a pair of sports shoes inside."Wheres the teapot?” the two thieves shouted at the top of their voice with red faces." How dare you cheat us? We saw you give your daughter a box at the airport. Come with us! We're going to search your home, one of them said。

    When the thieves entered Mr. Chan's flat, it was dark and quiet. All of a sudden, the door closed and the lights went on. The police were waiting inside.

    Amy and her mother came out of the bedroom with the teapot. "That teapot is very valuable, said Mr. Chan. "A long time ago it belonged to an emperor. He drank tea from it."

    “We were going to drink tea from it, too, "said Amy, laughing.

    March 20th is World Water Day every year. According to a report from the United Nations, more than half of the world's major rivers have serious water loss and are polluted.

    The Yellow River, the world's fifth longest river, watered some of the oldest farms on earth. {#blank#}1{#/blank#}Its source（源头）on Qinghai-Tibet Plateau is drying up. In most of the past 35 years, it didn't reach the sea.

The Nile in Egypt, running 6, 650 km, is the longest river in the world. {#blank#}2{#/blank#}Now it is down to 2 billion m³ or so. Australia's Murray River reaches the sea only every other year. One fifth of America's Rio Grande has no water, either.

    {#blank#}3{#/blank#}

    Mostly it's damming（筑坝）and global warming that make rivers dry. {#blank#}4{#/blank#}Now about 45, 000 of them lie across the world's rivers. They hold back around 15% of the world's fresh water from running to the sea.

{#blank#}5{#/blank#} Warmer weather takes water away. The glacier（冰川）are becoming smaller. The source of the Yellow River is drying up because of it. Global warming has had certain effects on water sources. Droughts happening around the world make people pay more attention to this fact.

    Eaten any wood today? You may have! And you possibly brushed your teeth with it and you are even dressed with wood. You might know that paper is made from wood. But we get a lot more from trees than paper! In fact, more than 5,000 wood products make our lives better each day. It's true! From toothpaste to photo film, wood products are all around us.

    Wood resin(树脂) is one of many chemicals we get from trees. When a tree gets hurt, resin will form as a protective(保护性的) coating around the wound to stop the insect. People collect the resin and use it to produce paint, glue and soap.

    There are also tree-based chemicals in many of the foods we eat and drink. Some of these chemicals are used to add colours to soft drinks, others to keep food from going bad too quickly. For example, snack food, milk shake and ice creams can be made with cellulose (纤维素) from trees.

    Our life is full of products that come from trees. Now, how many tree products can you see from where you are sitting right now?
