One possible version:
A Ten-Minute Break
As students, we have classes from early morning till late afternoon. Therefore, to take a ten-minute break between classes is definitely important, even necessary. Otherwise, we may feel both physically and mentally tired.
During the ten-minute break we do something to get rid of tiredness. What we need is to have a real rest, instead of getting more tired. So don’t do anything that will make you too excited.
My ten-minute break is always pleasing. I usually do some simple exercise. Sometimes I have a free chat with my classmates or just take a walk during the break. When the new class begins, I feel fresh again.
