LIFE IN UNIVERSITY AND HIGH SCHOOL
With the time passing by then I got accustomed to the university life,I find many differences in university comparing with the high school.
Firstly,we have more rights of choice,it’s we ourselves to choose elected course that we are interested in,and no one around us will force us to do what we dislike.Secondly,we have more freedom.For we don’t have so many classes each day as in high school,we can take part in countless activities after school.Meanwhile,the life in the university brings plenty of challenges.On the hand,we have to learn knowledge meanly by ourselves,since we can hardly meet our teachers out of class.On the other hand,we have to spend a lot of time washing clothes,buying food,etc.Thus,what we care about are not just studying and playing.
Considering the transformation from a teenager to an adult,the changes in this life stage are essential.Only when we overcome the difficulties and get used to the changes can we grow up to a real man who can enter and stay in the society successfully.And I believe I’ll do better and better in the next four years.
