Помогите написать текст вернее дописать по английскому тема телевиденье.

Вот начало:

 Now I will tell you some words about television and propose what to watch. Nowadays TV is very important for us, we are getting a lot of useful information from it. People watch TV all day long, they can’t live without it. But TV isn’t perfect, you can see a lot of advertisement and boring programs there. And of course everyone like certain kind of TV programs. So question "What to watch?” is very actual now.

                I watch television no above 3 hours a day. I think it isn’t too much to be bad for my eyes, but enough for me to enjoy it. My favorite program called "How it’s made”. It broadcasted by "Discovery channel”. It is commercial channel, so you can see it only by buying cable TV channel pack.

                "How it’s made” is a very interesting educational program. In this program you can see how and from what was made things, which we use every day. Of course by watching this program people also understand how to use this things. I propose everybody to watch this program, because I think it’s very useful.
