英文小作文：

Title: The Dirty City

Once upon a time, there was a beautiful city filled with color and life. But now, it"s a dirty and unpleasant place to visit. The streets are covered in filth and grime, the air is foul with bad smells, and the houses are covered in dirt and neglect. People walk around with their heads down, avoiding eye contact with others, as they try to avoid the piles of garbage and dirty streets.

But what can we do to change this? We need to start by cleaning up the city, removing all the dirt and grime, and making it a healthier and more pleasant place to live. We need to plant more trees and flowers to filter out the bad air and provide a green space for people to enjoy. We need to enforce laws against littering and other bad behaviors, and we need to educate people about the importance of keeping our environment clean and healthy. Only then can we restore the beauty of the city and make it a place worth living again.
