放学前必须把作业交起来吗？

Is it necessary to hand in the homework before the school is over?
楼上：短语别乱用！
哪有hand up！！！！你自己YY出来的！
class is over是下课
school is over才是放学~
你连皮毛都不知道~

hand up hand in 啥区别？ 忘了 好像没schoolwor吧

二楼的单词拼写有误,而且看起来对英语只是皮毛、一知半解。homework 指家庭作业，schoolwork 才是学校作业。另没有school is over，只有class is over 或 after school

Homework after school to be put together to pay it?
