How you learned to use it
How long you have had it and explain why you find this piece of electronic equipment useful.
Nowadays, with the development of the society and the development of technology, people’s lives become more and more convenient at their work as well as at their house. I think television is a piece of electronic equipment that I find very useful in life. It is very convenient and easy to use. You just turn it on and watch everything you want. My parents told me my house had the first television when my parents got married. Recently, we bought a new television because the old TV was out of date. I think TV is useful and convenient electronic equipment because you can watch and learn many things and you do not need to go outside. I think it is really out of the world when you just stay at home, but you can see many countries and many beautiful scenes which you have not to go to there. You can know much news around the world and you can learn about life through discovery channel. Besides that, through TV, I can see many poor people who have to burn the candle at both ends to earn money for their families or for themselves in order to find that I am very happy now. Those are the reasons why I think television is a piece of electronic equipment that I find useful.
