When I first entered high school, I knew no one at my school. All my friends in middle school went to other schools. I wanted to make some new friends. However, I was shy and wasn't good at making new friends. On my first day at school, I looked at others who were talking in groups happily. How I wish I were one of them! I guess I was very lucky then. At lunch in the dinning hall, when I was eating at a table alone, a girl came to me. "Excuse me, is this seat taken?" she asked. I immediately shook my head. She smiled and sat down opposite  to me. I felt a little _ and didn't know what to say at all, but I really wanted to communicate with her. It was a good opportunity to make friends with her. When I looked up, I found she was smiling at me. Her smile calmed me down. "I really like this school. It's beautiful, but I don't know anyone here. All my friends went to other schools," said the girl. Hearing her words, I immediately said, "my friends are not here either. Can we be friends?" I was surprised. I couldn't believe I would say something like that, and to my surprise, that girl immediately said "yes". We both smiled. We became very good friends. Now it's the beginning of a new term again. Many students may have no friends at their new schools. If you are also as shy as I used to be, please don't be afraid to talk to others. You may get a surprise and make a new friend. After all, others want to make new friends, too. What's the author's purpose in writing the passage?
To show that high school is really exciting. To encourage shy people to talk to others. To tell us how lucky she was in high school. To advise us to have a good first day in high school.
