Everybody knows that Beijing is changing.From buildings to the public transportation,everything is changing.And Beijing is becoming better and better.
Last year,Beijing had held the 2008 Olympic Games successfully and had become the focus of the world.
The change of Beijing is inevitable,because China is developing,and the world is developing.
The better Beijing changes,the better china changes.
Yesterday,the president of U.S.A has come to visit Beijing,which means Beijing has developed better than before.
If one day I have a chance,I will develop Beijing to be the best city in the world!
