Most children like watching TV. On TV 1 can learn a lot, and they can see and know many things 2 their country and the world. Of course, they can 3 over the radio, but they can learn better and more easily with 4 . Why? Because they can hear and watch at the same time. But they can't 5 anything over the radio.
Many students watch TV on Saturdays and Sundays. They are very busy with their lessons on 6 . But a few students watch TV every 7 . So they go to bed very late. So they can't have a good 8 . Also, it's 9 for their eyes. Usually they can't get up early the next morning. Of course, these students can't learn 10 because of the tiredness.
