DearDavid
I’m glad to receive your letter. I’ve learnt that you areconcerned about the smog which frequently strikes some cities and areas ofChina. Thanks for your concern. I’m also very worried about such terribleweather because it has brought much inconvenience or rather harm to people’shealth such as traffic jam, road accidents, bad coughs and even lung cancersand so on.
As is known to all, good environment comes from carefulprotection. So we should do what we can to protect it. I believe a small stepcan make a difference. Try to drive less and choose air-friendly products. Onlywhen everyone has the environmental awareness can we have a blue sky.
Looking forward to hearing from you and share your goodideas.
