The changes to Nanjing
Nowadays,when I walking in the street,I have a strongly feeling of the changes to Nanjing.In the past,the air was clear and trees were around the city.Streets were narrow,and people had to go to work by bike or by bus,they lived in a poor life with small house.At parent,Nanjing changed a lot,the wide streets ,and we build up a new airport,we can also take a clean bus or taxi,subway which is considered convenient.We live a modern life but it brings contaminate,so we should take actions to change it.
