Some people say they have an answer to the problems of car crowding and pollution. In many cities, hundreds of people ride bikes to work every day. In New York City, some bike riders have even  1    a group： Bike for a Better City. They say if    2    people rode bikes to work, there would be fewer cars and less dirty air.

        For several years this group has tried to get help for bike riders. They want to have special roads for bikes only, because when bike riders must use the same roads  3     cars, there may be accidents. Bike for a Better City feels if there were bike roads, more people would use bikes.

        But    4    bike roads have been ready yet. Not everyone thinks it is a good  5     . Drivers don't like it, and some shop owners don't,    6  . And most people live    7    far from the city to travel by bike. Still,    8    has been done about it. On Saturdays and Sundays, the largest open park in New York is     9     to cars, and the roads may be used by bikes only, but the group still says this is not enough and goes on fighting    10   bike roads.
