Dear Bill,
I'm glad to receive your letter,thank you for your caring for the weather and my health.Now I'd like to tell you something about the smog.
Since the winter last year,the smog has occurred a lot of times.it has done great harm to our daily life.many traffic accidents happened just because of the heavy smog weather,more and more people have to go to see the doctor because the serious disease caused by the smog,quite a lot of flights have to be put off,a great number of people have to stay at home for fear of the poisonous air caused by the smog.
People have realized the great harm caused by the smog and the importance of protecting the environment.people all over the country are taking measures to reduce the smog weather.the government suggests people go to work or school with the public traffic, such as the bus and the underground.Also we should plant more trees.
According to me, I will go to school by bike or on foot, and I won't throw the waste anywhere.in addition, I will tell the people I meet to protect the environment as possible as they can.would you like to tell me some good ideas?I'm looking forward to your reply.
Yours Sincerely
Li Hua
二、今年(2013年)除夕到正月十五期间，北京雾霾天气出现的天数占到50%以上，严重影响了老百姓的生活和健康。请写一篇短文，描述一下北京雾霾的情况，分析雾霾出现的原因，并提出治理雾霾的措施。
注意：词数不少于100词。
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.
