As everyone knows, we have a lot of homework, and every night we work late. On weekends, there is not even time for us to do the things we want to do. Teacher, why do you still assign us repetitive homework?

众所周知，我们的作业非常多，每天晚上要做到很晚。周末也没有多少时间可以做自己想做的事。为什么你还要叫我们做两次相同的作业呢，我的老师？ Everyone know that I have plenty of homework to do. Every night I have to work till late. Even during the weekends, I don't have much time left for myself and yet you want us to repeat the same exercises again. Why my teacher?
