The little city which I lived in when I was very young was so beautiful in the past time. There were many green trees and many kinds of fish swimming in the long river.The houses there are simple and crude,the streets are very narrow,and the people there were poor but kind. But now,my hometown changed hardly.There are many high blocks and supermarkets ,many cars running on the roads,the industry improve the economy but break the pretty scene there .The trees were cut down and the fish cannot be seen in the limpid water.It is of great importance for us to improve the environment there.
