　　注意：词数不少于100词。

　　【参考范文】

　　During the 15 days from New Year’s Eve to Lantern Festival, Beijing was affected by smog for more than half the time, because of which people suffered a lot. On the road people drove slowly because they could not see clearly. People also suffered from many illnesses caused by smog.

　　The smog in Beijing has been caused by many factors, in which the increase of cars in the city area plays an important role. The carssend off a lot of poisonous gases, which in turn adds to the already seriousair pollution.

　　In my opinion, the number of cars should be limited.We should call on the people to use more public transport. Only in this way canwe expect to have more sunny days.

　　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.

　　Yours Sincerely，Li Hua
