Recently I’ve had a discussion with my parents about if teenagers should go out with friends on weekends. My parents think that teenagers should stay at home on weekends. They should go over (复习)their lessons. And they could have enough time to have a good sleep. They also think teenagers should help parents (to) do some housework on weekends.

What’s more,(而且) we can also take some exercise toget
