| Most adults(成年人) once studied at school,had classes and did their homework every day.The same 1 is going on at school now. 2 it seems that doing weekend homework is 3 problem for the modern students. All the student should agree that weekend homework should be abolished (取消).It’s 4 for them studying at school five days a week.With homework to do on Saturday and Sunday,when can they find 5 to help around the house,go and see a game,or just have 6 at home? Because of these other activities(活动)，the homework can’t be finished until 7 so their homework is usually done in such a hurry that on Monday teachers are 8 and often threaten (威胁)to fail whole class of students because they know nothing about the 9 .If there were no weekend homework for the students to do ,they would be happy to go to school on Monday 10 having a good rest and to learn what the teachers teach. | |||
