it's harder and harder to be a student now. we always have lots of things to study. sometimes we just can't stand it. we are students, but we are human also. we want some spare time to play and relax. but now how can we do that with so many classes and so much homework? yesterday,one of my classmates told me that he spent four hours in the night on his homework.

　　he couldn't go to sleep until midnight. we have the same experience as he does. the burden is too heavy for us. we are too tired. we can't even pay attention to what the teacher says in the class.
