I think stuents should participate more school activities because we can learn more knowledges and talents from school activities,such as participating debate competition can improve students's eloquence,setting up a group of animal protection can learn how to love the animals,participating in two camps of psychology can know more about what is psychology,making pen friends can improve students's writing skill,english level and social contact an scaling the highest mount of Africa can test students 's courage.Also,they could learn the group spirit and conquer difficulties in the trip.
In my opinion,participating school activities is a meaningful thing because students wouldn't just sit in the classrooms and learn from books.Students could learn something from school activities which students couldn't learn from books or other ways,such as leader ability,interpersonal relationship,speaking skill,planning ability,team work and originality.These knowledges and talents can help students to work better when they have to work in the society in the future.Moreover,participating school activities can also help students to broaden their views and bring their protentials.Therefore,I think participating school activities is a good hobby,it could make students to study happily.
However,I suggest students shouldn't participate too many school activities because it may affect their study if students couldn't plan the time properly.
