Dear Mary,

     You say in one of your emails that you are worried about your little boy Frank, because he always wants

you to buy him toys that he learnt about on television. I don't think children should play with the commercial

(商业的) toys. When you were young I used to give you big cardboard boxes to play with as well as building

blocks (积木), books, paper and colored pencils. I expect you to do the same.

     Adults are also much influenced by the things they see on television. If you think about what you see on

television, you will find the money that people earn from their jobs can't support the lifestyles they have. The

apartments in TV programmes are far too large and have the most up-to-date furniture. This always makes

you sad when you compare what you have with what you see on TV.

     If I were you, I would buy Frank the movies and stories that I think are good and interesting. I would have

a good collection of them and I would borrow books from the library. But I would not allow Frank to watch

television. I tell you: it surely makes for a much more pleasant and easier life.

     I prefer to keep him away from advertising, and let him have more time to read, and select his entertainment

(娱乐) for himself. I hope you will find this idea of not letting your little guy watch TV to avoid the advertising

useful to think about.

                                                                                                                                            Warmly,

                                                                                                                             Canada, Mum Linda
