a: what do think about the advantages and disadvantages of tv?

b: i think it's good for our life.

a: why do you think so? my opinion is different from you.

b: it can provide us with abundant information,such as latest news over the world,history,culture and interesting stories.it can broaden our eyes easily so that we could acquire knowledge out of books.

a: maybe,you are right.but don't you think when you watch tv,it is easy for you to ignore he time being exhausted rapidly.at present,there are increasingly interesting tv programs which actually have little meaning for us, or even are bad for mental health.such as adult films.

b: so,we must learn to choose an appropriate program when we are watching tv.as for children,they can watch tv with their parents' company or admisio,while,as for adults,they should beware which is suitable or which is not suitable for themselves.if people do like these, tv's advantages i have mentioned must bring about in our life.

a: but few adults could control themselves and few children have their parents' company when they are watching tv.most people spend too much time in tv programs,fogetting their own work and study,even losing their sleeping time.it is bad for life.

b: as is known to all,tv is inevitable for us.when people come home from work,they always watch wonderful tv programs together with their family members,not only to relax themselves,but also to go information outside.tv brings to them.

a: ok.maybe both of us are righ.tv has both its own good merits and bad merits.whether it's bad or good ofr us is determined by our cotiudes toward it.
