One cold winter night in Shanghai, I was walking home at one in the morning after long tiring work. I was having trouble with my job in the bank. As I walked, I thought seriously about giving up living there. City life had become too much for me.

 As I walked down empty streets, I felt very small and cold. I began running, both to keep warm and to keep away any possible danger. Very few people were still out except a few sad-looking homeless people under blankets（毛毯）.

 Suddenly, I heard a sound behind me. I turned quickly, all I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. When I reached home, I realized what the noise had been. It had been my wallet falling to the sidewalk.

 Now I wasn't cold or tired anymore. I ran back to where I'd heard the noise. Although I searched carefully for fifteen minutes, my wallet was nowhere to be found.

Just as I was about to give up the search, I heard the garbage truck（垃圾车）come to me. When a voice called from the inside, “Alisa Chen?” I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man “Is this what you're looking for?”he asked, holding up a small square shape.

 It was nearly 3 a. m. by the time I got into bed. But I had got my wallet back. I also had got back some enjoyment of city life. I realized that the city couldn't be a bad place as long as people were willing to help each other. 

Unfortunately, three men died in a car accident. Soon they found themselves at the gate of heaven and saw God. Before getting in, God asked each of them the same question. If they could answer the question perfectly, they would be allowed to get into the heaven.

    "I'm sorry for your death," said God. "But when you are in your casket(棺材)and your friends and family are standing beside you, what would you like to hear them say about you?"

    Afraid of being refused, the three men were nervous. They thought for a while.

    The first man said, "I would like to hear them say that I was a great doctor of my time, and a great father to my children." Hearing this, God let him in.

    The second man said. "I would like to hear them say that I was a wonderful husband and school teacher who made a great difference to children." God agreed and let him in too.

      Then it was the last man's turn. He looked anxious and replied, "God, I have lots of things to do for my family and the world. So I would like to hear them say, 'Look! He's moving!' "

    At the beginning of the world, a man named Ekon lived in Luzon. He liked to build things. He thought it would be a very good idea to build a bridge to the sky.

    As he wanted the bridge to be strong and last a long time, he built it of stone. He worked for years and years to build the bridge. His wife and children, nephews and nieces, uncles and aunts, all helped him. Though they worked very hard, the sky always seemed to be a long distance(距离) away.

    When Ekon became an old man, his wife and children told him that he would never finish it.

    "If I can't finish it." he said. "my children's children will do so. "

    But just before he died, his wife and children told him that they could not find any more stones.

    So Ekon became very angry and disappointed. Though he was very old and weak, he pulled down the bridge. It came tumbling(倒下) with a great roar(吼叫).

    The stones made great heaps(堆) all over the country. These great heaps of stones are what we now call mountains. Ekon was buried under one of them himself.

    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.

    Health Benefits of Bicycling:

    It helps to prevent heart diseases.

    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.
