As students, we had classes from early morning till late afternoon. Therefore, take
a ten-minute break between class is definitely important, even is necessary. Otherwise we
may feel both physically and mentally tired. During the ten-minute break we do something
to get rid of tiredness. That we need is to have a real rest, instead getting more tired. So don’t
do anything that will make yourself too exciting. Your ten-minute break is always pleasing.

take a walk during the break. When the new class begins, I feel fresh again.
