Time flies.Many things have slipped away(溜走） before we could cherrish
（珍惜）.1 year is not long time,nor is it short.We were naive（天真）
highschool students 2 years ago.Now we are in the ivory tower.(象牙塔）
University is like a paradise（天堂） because you can learn whatever you
wanna learn. University is like a hell because you can also shatter（破
灭） your dream by the endless degradation.We are facing the same
serious topic.Maybe the cozy life in university made us slothful（懒惰）
.The brilliant achievements（辉煌成绩） we ever got made us arrogant（自
大） and complacent（自满）.So such behaviors like skipping classes
became to be a necessity in our daily life.until the school report came
out,we got to know our marks.Silence we were.The cruel test paper
dragged us back to the reality.And as a proverb saying "Rainbow appears
after rain".We should treat the exam properly.It let us back from the
wrong track.
