1、It is reported that a certain city has advocated“Ride to Work Day”recently．Personally I think We should be in favor of it．

    Everyone knows that air pollution is mostly caused by waste gases produced by cars． However the number of private cars still goes up，which worsens global warming．So I’m strongly against owning and driving private cars

    As a matter of fact，we can benefit a lot from bicycle riding．First, it can save a large amount of energy，which helps protect the environment．Second, riding a bicycle．every day can build up our bodies．In addition．it call relieve traffic pressure and in the meantime it’s easier for us to find places for our bikes．Actually．in big cities riding a bicycle can be faster than driving, a car because it call be free from traffic jams．
