                    Social activities and Our Study
     Social activities benefit us in many ways. To begin with, these activities can widen our knowledge, because we can learn from these activities what we can't from our books. Secondly, these activities can serve as a bridge between theory and practice. Lastly, they can enrich our experience, because we can get to know society well so we can adapt to it easily when we graduate.
     Too many social activities, on the other hand, will cause a lot of problems. Study is the most important task in our daily life and social activities can only, and should always be a supplement. If we involve in these activities too much, we will never be able to learn knowledge well.
     Therefore, it is suggested that we students spend most of our time and energy studying, and once in a while participate in some social activities.
