My grandfather never watched TV. He thought that (A)人们花费太多时间看电视. (B)Some of his friends often talked about sports shows, the movies and plays. My grandfather said to himself, "They never read any books or go out in the evening. So he didn't buy a TV.

      Five years ago my grandfather was 60 years old. He stopped working in the hospital. My father bought him a TV. He began to watch all the news. He knows much more about the world now. And he reads more books, too.

      Now, my grandfather will get very angry if you trouble（麻烦）him when he is watching TV.  I can't know that one can change (改变）his idea when he is 60.
