Great Changes in My Hometown
In recent years, great changes have taken place in my hometown. I have seen the changes myself.
In the past, there were no flowers and grass here. There were only narrow and dirty roads. The water was dirty and smelt terrible. What’s worse, some factories put the waste water into the river. A lot of people liked to use the disposable paper cups and paper lunch boxes.
But now everything has changed a lot. There are many beautiful flowers and grass everywhere. The streets are wide and clean. The water is also clean and the air is fresh. And you can see bees and butterflies dancing among the flowers. Most people have realized the importance of protecting the environment. To reduce air pollution, they often walk or ride bikes to work instead of driving cars. To reduce waste pollution, they seldom use the disposable paper cups and paper lunch boxes.
Now people are enjoying a comfortable life.
