一、Great changes in my hometown More than twenty years ago, my hometown was just a small , old and poor town. Most of people were farmers. There were few factories. The people didnt have enough food to eat and wore old clothes. They had a hard life . Great changes have taken place in the past twenty years . The people have found a lot of ways of making money . Now there are many tall buildings . They are very beautiful . Roads are wide and clean . People can take buses or drive their own cars to go to work . Many people have cell phones and personal computers. Peoples living conditions have improved a lot . Thanks to the governments efforts . my hometown is becoming more and more beautiful . 二、Save the earth How to protect the environment has become one of the biggest problems in the world . Its our duty to protect our environment . No matter where we live , we should do something to keep our neighborhood clean and tidy . We can collect waste paper or other waste things for recycling. We should plant more trees and we should prevent those factories from pouring waste water into rivers, lakes and fields. We shouldnt leave rubbish everywhere and spit in public places . We mustnt pick the flowers or step on the grass in public. If everyone tries his best to protect the environment , the world will become much more beautiful and our life will |
