I often quarrel about my mother over whether I can watch TV after school. She holds view

that senior three students have to make fully use of every minute to work hard at their lessons. It

seems to me that once I am allowed to do that, I’ll unable to control myself and forget all about

my study. She also thinks it is bad for my eye. And I really can’t accept her ideas. In my opinion,

watch TV can set my mind at rest after a day’s hard work. Besides, it is important for us to know

what had happened at home and at abroad. Thus, we shouldn’t be forbidden to watch TV.
