1.四年级下册英语作文我的风铃

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
