【正确答案】Dear Sir or Madam,
I'm writing to you to express my willingness to take part in the controversy on private cars.
With the living standards rising rapidly, more and more Chinese people have ears of their own. Statistics show that in Beijing alone, there are 1,620,000 ears, among which private ears add up to 560, 000. Whether private ears should be encouraged in China or not? People differ in their opinions about it.
Many people are against owning ears. The reasons for it are obvious. To begin with, ears contribute to air pollution. A lot of big cities in China are now plagued by serious air pollution. Secondly, private ears can be a dire threat to the already terrible traffic in China. If more cars are allowed onto the busy streets, more traffic jams will happen, which is really a public hazard to all of US.
In my opinion, private ears should be discouraged in China. To leave clean air, wide and safe roads and abundant energy resources to our descendants, we have to say "No" to private cars.
