When I was a boy, I didn't have any hair on my head. So I was very shy. I liked to watch my friends play in the park. Sometimes I would join them, but most of the time I just watched them play.
Every day, we would see an old man walking in the park. He had big ears and no hair. We thought he was dumb (哑的). Every time when my friends saw him, they would say loudly, "Hey, Mr. Dumb, what's the time?” But they got no answer.
One early evening, I was standing outside my house, and I saw the old man coming. I was not with any of my friends and there were no other kids around to say the usual words of "greeting( 问候)”.
But how could I let the old man walk by without saying anything? So for the first time, I asked, “Hey, Mr. Dumb, what’s the time?"

2.The boy’s friends were very polite to the old man.

Television keeps one learning more about present events, allows one to follow the most recent developments in politics and science, and offers various programs which are .both instructive and exciting. The most distant countries, the strangest customs and the most attractive scenes of nature are brought right into one's room or house.
However, some people insist that television is bad rather than good. They argue that it has brought about many serious problems. The major one is its effects on young people. Children are now so used to getting their information and entertainment from television that their ability to read and write as well as physical ability has been greatly weakened. Even worse than that, vulgar( 庸俗的) advertisements and poor programs may develop their bad tastes, shape their view points badly towards human life to such a degree that their minds might be destroyed.
