There were a lot of big trees and the air was fresh. Yet, the area has changed a lot over the years. In the past, people could only go to Nanjing by bike or on foot. But now, things are different. Many buses pass there, so if people want to go to Nanjing, they can take a bus. Of course some of the people in my hometown have their own cars, and they can drive the car to any place they like. In my opinion, my hometown has become a modern town. But the changes to my hometown have also caused some problems for people. For example, people want to make more space for modern buildings and roads, so they have cut down a lot of trees and the air is not as fresh as before.
