1,my family lives in a historic city,the past five years I witnessed the city changes.
2,five years ago,the streets are small shops and narrow streets crowded.
3,it is very environmentally conscious,full of garbage.
4,now change the width of the street,and street trees and flowers planted.
5,and another four new parks,a variety of high-rise buildings are going up.
6,in the urban construction and development,we should also strengthen the conservation to cultural heritage.
