　　As for me, I bear the belief that one of the most effective ways to reduce the air pollution is to advocate riding bicycle in the country.
　　The most typical example might be the bicycle-riding culture in Holland, which embellishes Holland with the unique charm. 40% of people in Holland regard bicycles as the main transportation. No matter who they are, no matter what they do, they ride bicycles from home to job, which greatly relieve the traffic congestions and reduce the air pollution.
　　Just imagine that one day people in our country ride bicycles in the breeze and sunshine, enjoying the beautiful sceneries and breathing the fresh air. How fantastic itis! So I reckon that if our country takes this measure, the air pollution will be reduced definitely.
