【答案解析】I prefer to watch educational TV programs because I believe that knowledge can be learnt everywhere. Watching educational programs can broaden my horizon, and I really enjoy those programs taking viewers into the wild nature and explore something we don't know. It's amazing and I may never have the opportunity to experience them myself. Also, some programs can teach me how to improve my academic performances in various terms. Last week, I learnt some writing tips from one TV program and successfully applied them in my own writing. In summary, I benefit a lot from watching educational TV programs.
