Mang parents think students should go to cram school at weekend. And we should not go out with our friends.But I think it takes great pressure for teenagers to study ,we should be allowed to go out with friends at weenkend.after having study for a week,we need to have some time for ourselves.I think it would be helpful for our study,and we can learn more knowledge from our friends about some interesting tings.Even if allowed,we also must pay more attentions to our safety,
