还是一篇作文,帮我看下有没有什么错误的地方或者哪里的语句有更好的改进方法的~
Time flies and when I realized it I have already been a sophomore.Looking back into the first year I have spent in the college,I can clearly found that I have really learned very much and grown quickly.
I can still remember the first several weeks in the college and they are quite busy and difficult to me.As a college student,I have to learn how to handle the life and work and study well.I know I should learn to do most of the things by myself.At that time I nearly lost myself.However,I tried to struggle and finally find a better way to balance my academic life.
During this year,I joined the school student union and took part into many activities.All of those made me realize that I can also do many things and my academic life can be colorful too.
Now as a student in grade two,I am still not sure what should be my life plan but I am sure I will still do my best and keep trying.Life is always full of challenges and I will be a good fighter.
