well,first,school is a place where we can get knowledge.Teachers and classmates pass their knowledge to us.We can learn some skills and practise our minds in order to find a job in the future.
Second,we meet classmates,make new friends at school.Gradually,we learn to have social abilities.In the future,when we guaduate from school,we will have a better adaption to this society.
Last but not hte least is we can learn how to live lives and be a good person at school.We are taught to be honest or be punctual,etc,from teachers,textbooks,parents,classmates and so on.Little by little,when we grow up,we can own some necessary qualities to ne a social man.
