Dear David,
I'm glad to receive your letter. I have learned from your letter that you are concerned about the smog which frequently appears in some areas of China.
Thank you for your concern. I'm also very worried about such terrible weather because it has brought much inconvenience or rather harm to people's health such as traffic jam, road accidents, bad coughs, throat hurts and ever lung cancers and so on.
As everybody knows, a good environment comes from good protection. So we should do what we can to make a difference. Try to drive less and choose air-friendly products. Only when everyone has the environmental awareness can we have cleaner air.
Hoping to hear from you soon and share your good ideas.
