     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 monitor 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 outofclass 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.

A. he was unable to work out the puzzle

A. his home was far from the school

3. After his first week at school, the author ________.

A. was still not accustomed to the schedule
