Recently, our school has held the meaningful discussion on whether it is reasonable for middle school
students to have classes on weekends. Some of our classmates believe we should have classes on weekends
because we can make fully use of the free time to review the lessons we had learnt. Some others are against
the opinion, saying we had better to have a good rest on weekends so that we can work effective during the
weekdays. The rest agree with neither of the opinion. They have the view which keeping the balance between
work and play are both important for us. They suggest one day of the weekend should used to learn our
lessons and during the other day we do something interested or have a rest.
