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 about 1.4 billion bicycles and only about 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 (可折叠的) 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 also take a common bike with you when you fly. But be sure to look for information by accessing on airline websites. Not all airlines are bicycle-friendly to travellers.

    Bicycling helps to control your weight.

    A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a year. Bicycling can improve your mood (心情).

    Exercise like bicycling has been shown to make people feel better, more relaxed and self-confident. Bicycling is healthier than driving.

It was a sunny summer day and I walked back home from school. When I stood (站在) in front of my 1 , I found I lost my key. It was very 2 for me, because I only had one key. And my parents were out for some days.

I walked around the neighborhood, wishing to find the lost key. But I didn't find it. I 3 my mom and she told me to go to my aunt's home. My aunt lived in another house of our neighborhood. I could 4 with her that day, but I still needed to get my key back.

The next day when I went past the security hut (保安室) in the neighborhood, I saw something on the window. It was my key! "Is that yours, boy?" the guard (保安) asked me. "Yes. I lost it yesterday. 5 found it?" I said. The guard answered, "I don't know. Someone picked it up last night."

I was happy. I couldn't thank the person, but I can pass on (传递) his or her kindness.
