听力原文：Dear Sir, After watching the discussion about boxing on television last night, I felt I must write to you. Before I saw this program, I had not given any thought to the dangers of boxing. However, thanks to your program, I am now aware of the dangers. Sluice the government seems unwilling to ban boxing, it seems that the general public must do something. I am particularly concerned about the dangers to young boys who attend boxing clubs. But, in spite of all the publicity about the harmful effects of boxing, parents still let their sons attend these classes. Although I believe that people should be free to choose their own sports, I feel that boxing is not a sport and should be banned. I should like to invite your audience to write to me and tell me their own views on this matter. If there is sufficient support, I shall start a Ban Boxing campaign. Yours faithfully, Erwin Nathan What had been the writer's view about boxing before he saw the TV program?
