Of course they can also learn        the radio. But they can learn better and more easily      TV. Because they can hear and watch at the same time. But they can’t see        over the radio. TV helps        children’s eyes. TV helps to open their minds(智力）,too. They learn newer and better ways of        things. Many children watch TV        Saturday and Sunday. But some students watch TV every night. They usually go to bed very late. They can’t have a good rest.
