五、回答问题
Mr. John HeppellHouse of CommonsLondonSWIAOAADear Mr. Heppell, I am Sabrina Akhtar studying in a high school and I've noticed that forests are disappearing. You know, more and more forests are disappearing around the world each year. That is because of many different reasons including farming pollution, tourism pollution, etc. If we stop doing these things, there will be a good future for people. Now I'm writing to ask you to help stop forests from disappearing. You can help by getting shops to stop selling paper made from trees and change to tree-free paper (paper not made from trees). That will help forests so much. There are many things we can do to help protect forests. By changing the little things, we can make a big difference.If you would like to contact (联系)me, please see the above address or e-mail me at shazadinol@hotmail.co.uk.
