阅读理解。

     On the first day of my new high school, I almost had a nervous breakdown. Everything about the school

seemed so difficult. When I got home, my parents said, "You're nervous and that's okay. Everyone is afraid

of high school." I denied it. I wanted to be strong, so I refused to let anyone know about my fear, even my

closest friends.

     On the first day I was late for every class and was constantly lost. The school seemed like a puzzle that I

couldn't figure out. Was this how the whole year was going to be? I didn't think I could rise to this challenge,

especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with

it! The schoolmates seemed to regard me as a fool, and they were probably right.

     Despite my fears, after the first week I finally had my schedule figured out. With the exception of falling up

and down the stairs a couple of times and getting laughed at, high school was turning out to be not so bad. It

was actually much better than middle school and much more challenging.

     Since then, I've been elected vice president of my class, which wasn't much of a victory since only three

people ran for the four positions.

     It is normal to be scared about a new school. Take a deep breath and relax. High school is something that

any student can overcome. Make sure you participate in some out-of-class activities because you'll find it easier

to make friends. Try to do your best, even if it isn't straight A's.

     Most important of all, be who you are, whether you're a "fool", an athlete, or a lower grader. Don't try to

pretend to be someone you're not. Now you know the true secrets of high school.
