Time seems to be not enough for us senior students.As the result，more and more students try to study from early morning till later afternoon，even during the ten-minute break.In my opinion，taking a ten-minute break between classes are necessary.If not，they will feel tired both physical and mentally.During the break，we should do something get rid of tiredness.What we need of is to have a real rest，instead of getting more tired.So doing nothing tired in that period is really good for us.My ten-minute break is always entertaining.Sometimes I would like to take some exercises.Sometimes I have a free chat with my classmates or just take a walk outside.Although the next class begins，I feel fresh again.
