    Nowadays more and more Chinese go to work with bicycle, leaving their cars at home. Why are so many people riding bicycles to work? They have different reason for it.

    First, bicycles do not use up any fuel. Therefore, they cost less than other means of transport. Besides, bicycles do not need many space on the road, and it is easily to find a place for it. And everybody knows that riding a bicycle is healthy sport.

    When people drive their cars to work or shop, they lost the chance to exercise, but the waste gas from the cars will pollute the air. And moreover, people feel annoying when looking for a parking lot in the busy city center. So I prefer riding a bicycle to drive a car.

    Yesterday I was asked to send my grandmother to the school bus stop, because she is not able to walk through the snow with his walker. There was a mom walked with her little son in the same direction. The boy was screaming and crying all way. Before my grandmother left by bus, I walked back with the mom and she told me that the boy could make up sounds but no words at this point. I held up my hand to the boy, which was walking, and he took it. He was content with my hands while I chatted with his mom. I felt he trusted me. It made me very happily, too.
