Dear teachers and students, "APEC blue" is a popular phrase which describes how blue sky was in Beijing during the APEC week.How strongly we hope to make "APEC blue" a "forever blue"!But in the picture it is a grey day and hazy weather.The pedestrians on the road wear gauze masks and it's hard for them to breath. But there are still so many personal cars on the road.People in cars may not wear gauze masks,I think .What leads to the bad weather is mostly human pollution.What should we do to protect the environment.We should advocate green travel and give preference to public transportation. We can go to work by bike.What's more,we should use less plastic bags.Only by doing these,can we make our own efforts to build up the blue sky once more.

Dear Mary, Thank you for your letter. APEC blue refers to the blue sky during the APEC week. The air was very clear and we enjoyed the bright sunshine all over the city. We need to protect the blue sky because pollution is dangerous to our health. In order to keep APEC blue for a long time, we should take some simple steps now. First, we can take a bus or a subway to go to school instead of taking a car. Second, we’d better use cloth bags since they can be reused many times. Third, we can make some posters that will help more people know the importance of the air protection. I hope you will enjoy the blue sky and clean air when you visit Beijing.Yours, Li Ming
