In my opinion,every student should engage in some after class activities because from these activities we can learn many valuable things that we won＇t learn in classrooms.School is not just a place for learning the difference between "lie" or "lay",or what caused the hours of the daily schedule.Finally,after class activities broaden our circle of acquaintances.No amount of ordinary school work can take the place of friends acquired in the informal familiarities of activities.
