What do you think thaabout children useing computers every day, and what are the advantages or disadvantages of it?

Everything has its dual charactwo sides to the matter, and this one is no exception.

'Dual nature' sounds a bit odd here.

I think children can develop their brain, get in touch with new things and master advanced science and technology by using computers, but they should not use them every day, because doing so will beis harmful to children's health.

'doing so will be harmful' is fine, but it sounds more natural to use present tense.

For example, long time use of computersusing computers for a long time can hurt children's eyes, and if they play games on computers they will get addicted to them.

Meanwhile, using too manyhe computers too often will lead them to lack outside activities and that is also a bad thingmiss outdoor activities, which is bad for their bodyies.

'Using too many computers' sounds like the problem is that they are using many computers, not that they are using the computer for a long time.

These are just partsome of the advantages and disadvantages of children using computers every day.

Let's call it a day today and we will discuss it more next time.

To just 'discuss it next time' makes it sound like you haven't discussed it at all today.
