How I've changed
Time past quickly.I've changed a lot with the time going.
When I was young,I only know the most interesting thing in the world is playing.I played games with my friends day and night.I wasted a lot of great time.
But when I was a little older,I not only know playing.I realize learning is as important as playing,even much more important.I spent my whole day to study,study and study.but at that time,I do not know what "stress" means.
Then,two years later,I understood.I was going to graduate from primary school and,I need to pass a special test for the entrance of junior high school.I have no time to play.I have no time to have fun with my good friends.
After I had passed the examination,I felt more nervous than any time I was.Everybody was smart and I didn't have the great position.But I don't know what “give up" is.I spent more time on the subject I was not good at.So I won the first position later.
That's How I've changed.My life bocomes harder and harder,but I am not scared.I try my best to let my life become more interesting.
全是自己写的啊.写的不好,见谅..我才是个“primary school student”啦..
