Dear Susan,
Thanks for your last letter. I learnt from the letter that you are a volunteer for environment protection. I quite liked the stamps and photos you sent me. I wish I was there voluteering, too. You asked me about the situation of the low carbon life our school has been leading. I'm going to tell you how we are doing it.
Ever since we started this activity, we have been encouraged to go to school without using private cars. It's more environment-friendly to walk, ride a bike or go by bus. We have been developing good habits of saving power and water in our daily life. Even when we are doing our homework, we often pay attention not to wasting paper. We sometimes volunteer on the street to promote low carbon life to more people.
These are most of the things we do to live a low carbon life. How about you?
Sincerely,
Simon
