Dear Sir or Madam,
I am writing this letter to draw your attention to the community lecture concerns garbage classification. As we all known, garbage classification is quite important for environmental protection, so we should try our best make it.
Garbage classification not only benefits the environment, and it can reduce the workload of workers. More important, it can help us develop a sense of rules and form good habits for yourselves. What's more, the garbage where is classified can be recycled and turned into valueless resources.
The lecture will be held in the hall at 9 am next Sunday. I hope you can all come and join in us. Making a contribution to garbage classification, please.
Yours,
Hongqi Community

A city，whether big and small，should be clean. Only when we live in a clean city we live a happy life. As we know，a clean city，that disease may be reduced and people's health may be better，are good both to our mind and body. No one believes people lived in a dirty city with waste everywhere can live happy. However，as more and more people moving into our city，it is not easy to keep our city clean. Beside，some factories will pour waste into the air，the river and onto the ground，making it is hard to keep our city clean. To make our city the better place to live in，we still have a lot to do.

Last Friday morning, hardly had I reached school while my attention was caught by a big poster on the notice board, saying that it would be the World Earth Day in a few of days.
Responding active to this, my classmates set to work immediately. In the afternoon, we brought to school what they thought to be of little value. Use scissors and paste, we made shopping bag and artworks out of them. After school, we went to the local community and launched a campaign, giving up what we had made and calling on people to make best of what they thought to be useless. Meanwhile, we hold a lecture in the community to raise people' s awareness of protecting the earth. We had a busy but meaning time.
