In most parts of the world, many students help their schools make less pollution. They join environment clubs (环境俱乐部). In an environment club, people work together to make our environment clean.

    Here are some things students often do.

    No garbage (垃圾) lunches. How much do you throw away after lunch？Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school.

    No car day. On a no car day, nobody comes to school in a car-not only the students but also the teachers！Cars give pollution to our air, so remember:

    Walk, jump, bike or run.

    Use your legs! It's lots of fun.

    Turn off the taps! Do you know that some toilets can waste twenty to forty cubic (立方的) meters of water an hour？In a year, that would fill a small river！In environment clubs, students mend those broken toilets.

    We should love our environment. Let's work together to make it better.

    More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

    Get on a bicycle and ride around your neighbourhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and benefit(受益）from the enjoyable exercise without polluting the environment. You don't even have to ride all the way.

    Folding(折叠）bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can take a common bike with you when you fly, too. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travelers.

    Health benefit of Bicycling:

    ⒈It helps to prevent heart diseases.

    ⒉Bicycling helps to control your weight.

    ⒊A15-minute bike ride to and from work three times a week burns off five kilos of fat in a year.

    ⒋Bicycling can improve(改善）your mood. Exercises like bicycling has been shown to make people feel better, more relaxed and self-confident.

    ⒌Bicycling is healthier than driving.

    Bethany Hamilton is a professional surfer (职业冲浪手) in America. Her parents are both surfing lovers. As a baby, Bethany liked to play in the water. She started surfing at the age of five. By thirteen, she had been one of the best teenage surfers in the world. Then the shark attack (鲨鱼袭击) happened.

    On the morning of October 31, 2003, Bethany and some friends decided to go surfing. The sky was clear, and the sun was shining. The 13-year-old surfing star was lying on her surfboard (躺在她的冲浪板上) with her left arm in the clear, blue water. Suddenly a five-meter shark appeared and attacked her. Bethany saw the water around her tum red. She held on to her board and the shark swam away -- but it took her left arm with it. Luckily, the shark attacked only once. It all happened so fast that she didn't even shout.

    In her mind, Bethany thought, "Get to the beach. Get to the beach." She started to swim with one arm. She shouted for help. Her friends didn't know about the shark attack -- they thought at first that she was joking. Then they saw the red water and quickly came to help. It took her about fifteen minutes to reach the beach. They called 911 and. Bethany got to hospital at last. Surprisingly, she was surfing again in a competition only ten weeks later. And less than a year after the shark attack, she won first place in a surfing competition in Hawaii.
