完形填空
Most adults once studied at school, had classes and did their homework every day. The same 36  is going on at school now.    37  it seems that doing weekend home-work is    38  problem for the modern students.
All the students should agree that weekend homework should be canceled.  It's   39   for them to study at school five days a week.  They have a lot of interests. With homework to do on Saturday and Sunday, how can they find   40  to help around the house, go and see a football or basketball game or a good film, join in family recreations  (娱乐), or just have    41 _ at home? Because of these other activities, the homework can't be finished until   42 .  So their weekend homework is usually done in such a hurry that on Monday teachers are   43  and often threaten (威胁) to fail whole class of students because they know nothing about the   44 .  If there were no weekend homework for the students to do, they would be happy to go to school on Monday _ 45 _ having a good rest and to learn what the teachers teach.
