Jenna, a popular girl from Westwood Middle School, had graduated first in her class and was ready for new 1 in high school.
2, high school was different. In the first week, Jenna went to tryouts(选拔赛) for cheerleaders(拉拉队队员). She was competing against very talented girls, and she knew it would be 3 for her to be selected. Two hours later, the 4 read a list of the girls for a second tryout. Her heart 5 as the list ended without her name. Feeling 6, she walked home carrying her schoolbag full of homework.
Arriving home, she started with math. She had always been a good math student, but now she was 7. She moved on to English and history, and was 8 to find that she didn’t have any trouble with those subjects. Feeling better, she decided not to 9 math for the time being.

High school was just as her mom had said: “You will feel like a small fish in a big pond 19a big fish in a small pond. The challenge is to become the 20 fish you can be.”
