     Time fly like an arrow. I'm already in the second half of Senior Grade 3 before

I realized it. It is only a little more than three months before I graduate middle school.

At the present, I'm busy review my lessons in order to take the College Entrance

Examination. I hope to go to Beijing University, that is one of the best universities not

only in China but also in the world. I'll try my best turn my dream to reality. Most of my

classmates are also studying very hard to realize our wishes. I do believe everyone will

be able to enter an university or college.
