Dear David,

I’m glad to receive your letter. Thank you for your concern about the heavy smog in North China. Now I’d like to tell you something about it.

Since the winter last year, the smog has occurred a lot of times, which has brought much inconvenience to our daily life and done great harm to people’s health. Many traffic accidents have happened just because of the heavy smog weather. In addition, quite a lot of flights have to be put off and a great number of people have to stay at home to avoid the poisonous air . What’s worse, many people have suffered from bad coughs, sore throats and other serious diseases caused by the smog.

        Personally, I think not only the government but also everyone should try to make a difference. I strongly approve of the idea that we can try to drive less and buy environmentally-friendly products. Only when everyone has the awareness can we have cleaner air.

Hoping to hear from you soon and share your good ideas.

                                                                                                        Yours,

                                                                                                         Li Hua
