A feeling of excitement overcame me as I looked around the stadium.
At 5:30 pm, two hours before game time, I walked into the locker room (更衣室).My     of school, music and what I planned to do on Saturday night were       with the simple aim to beat the football team across the field from us tonight.
Approaching my locker (衣物柜),I noticed my teammates       .Some rested on benches, staring up at the ceiling       it were a film of the opposing team’s play. Some seemed a bit more       , using the time to tell jokes. A few stared at the field,        what will happen in 120 minutes.
Our coach, Tony Severino, came out of his office at 6 o’clock He told the team how       this game was for the season, between two of the state’s top teams _ my school and our opposing team, Liberty High School. His words gave the team impulse (冲动)it needed to       .
At 7:10 pm, warm - ups finished, we went over the game        and discussed what we needed to do for the next three hours. The sound of the national anthem (国歌)         that we were only minutes from the action. Our coach usually made a final         . But tonight was different. On this clear night he         looked around the room at all the players and shouted, “Let’s go and get them” Even         the “get” came out of his mouth, we were already         our way out of the door.
Outside, a few young fens reached to touch our hands, eager to be a         of our school’s winning tradition. When I smiled and         my hand, the young feces lit up as if they had just met Superman.
Seconds later, the team ran onto the           ,moving as a mass of blue, in front of a packed stadium. We enjoyed a noisy         from fens and the fight song played by our school band. Breathing in the         of one of the biggest game of the year, I felt we were sure to win. I told myself, “This was what it was all about” and         that it was for moments like this that I loved high school football.
