For a long time, television has been regarded as a saving means of entertainment and acquiring useful knowledge. However, besides the benefits mentioned above, it also brings a lot of harm because of the following reasons. First, watching TV takes up a lot of our time. I do not deny the benefits such as entertainment or education that it brings. However, instead of spending all the day just watching TV, we can do some useful works such as doing homework, helping mother to do housework. Through that, we can gather for ourselves a lot of soft skills and become closer to the other. Second, sitting too close to the TV screen will make harm affect on our health. Studies have shown that sitting near television will shorten our vision, in addition increase the risk of cardiovascular diseases and degeneration of the neck vertebrae ... These are the disadvantages that no one expects. Therefore, let's limit the amount of time spending watching TV and save that time doing other useful things.

Television is very important for our lives so most families have televisions. It provides us with information and entertainment.
What would you do after a hard day at school or at work and you want to entertaining. It simple, just turn on your TV. Music channel, comedy channel or cartoon channel... is your choice, just pick a channel. And not only entertaining, TV can also help you update the news from all over the world in the end of the day
We stay at home and know what is happens all over the world. You can watch you favourite  programs and game shows you . Someone spends 3 or 4 hours sitting in front of television.
There are too much advertisements on television which makes us tired. Anyway, TV is a wonderful invention. It is a cheapest kind of entertainment for everybody.
