       There should be no weekend homework for us. Five days given to school are enough for the modern students, who have many other interests. With

homework for Sunday, when can we find time to help around the house, join in a football or basketball game, volunteer at some public places, or just rest? Because of all these other acitivities, weekend homework is usually not done until Sunday night. It is often done so poorly that on Monday teachers scold (责备)  the whole class of students who have no idea of what the learned

lessons are about.  Without homework for the weekends, students could go

to school on Monday well-rested and willing to study. Teachers, don't you

agree with us?
