the after-class activities held by our school is having a good progression at present，the teacher are focusing all their attention on setting these activities。
the reason why i want to encourage everybody to join the activities is that it is just the after-class activities that i got some society experience from，so i think it is necessary that students join the activities，and i still think you should choose the activities that you like，and try self best to learn some society experience from the activities。
next，my suggestion for school is that teachers should regard whether every student have learned some experience well。
it is high time for everybody （should）join the activities！
