范文

Dear Bill,

I'm glad I received your letter. Thank you for caring about the weather and my health. Now, I'd like to tell you something about smog.

Since winter last year, there has been a lot of smog. It has done great harm to our daily lives. Many traffic accidents happened just because of the heavy smog. Quite a few flights had to be rescheduled, and many people had to go to the doctor because of serious diseases caused by the smog.

People have realized that smog causes great harm, and people all over the country know that protecting the environment is the most important thing to do. The government suggests that people go to work or school on public transportation, such as the bus and the underground. Also we should plant more trees.

As to me, I always go to school by bike or on foot, and I never throw garbage anywhere. In addition, I will tell everyone I meet to protect the environment as much as they can. Would you like to tell me some good ideas? I'm looking forward to your reply.

Yours,
