Our city is no longer what it was used to be. Nowadays, a lot of things have been done to make it more beautifully. Firstly, many trees have been planted around the city. The whole city is dressed on green. Besides, the polluting rivers have been cleaned up but there are more fish in the rivers. Moreover, a new park, that allows people to have fun and relax, has been built in a center of the city. Finally, people have been encouraged go to work by bike or on feet.
