an agreement
i am a senior three student. i often quarrel with my mother over whether i can watch tv after school. my mother holds the view that students in senior three, shouldering heavy loads, are too busy to spare any time to watch tv. it seems to her that' once i am allowed to do that i'll not be able to control myself and forget all about my study. she also thinks that it is bad for my eyes to watch tv too often. but i really can't accept her ideas. i think it a relaxation to watch tv after a day's hard work. watching tv can not only relax me, but broaden my horizons. now we've at last reached an agreement that i can only watch tv at weekends, and the programs should be limited to news,programs of entertainment, sports or science.
