Thank you for your concerning about the weather. Now Id like to tell you something about the smog. Smog has cause great trouble to us. First, more and more people are suffering from respiratory diseases, such as bad coughs, sore throat or even lung cancers. As a result, hospitals are crowded with people. Second, it has brought much inconvenience to our daily life like traffic jam, road accidents. Meanwhile, flights and ships have to be cancelled or put off. Whats worse, students have to stay at home because schools suspend classes. In my opinion, during the haze weather, wed better wear masks and reduce outdoor activities. In the meantime, measures should be taken to protect the environment. We should take green transportation, develop green energy as well as plant more trees. Hoping to hear from you soon and share your good ideas. Yours Li HuaImprove your letter after class and write it again as your homework.
