The basketball final between Perfect School and Sunrise School has entered white-hot stage. There are only fifteen seconds left. Sunrise School is one point ahead. Mitchell, who is one of the best players of Perfect School, is now controlling the ball. The students are extremely excited. They cannot help standing up and shouting, “Go! Mitchell!”Other teammates also encourage Mitchell, “Take a shot, boy!”

Mitchell knows it will be the last shot. He hesitates (犹豫) and falls into careful thinking. He imagines that he shoots from the halfway line. The hall turns quiet. All eyes follow the track of the basketball. It jumps round the ring over and over again and finally rolls out of the court. The world turns noisy. Mitchell sees his coach lower his head, his teammates kneel down and his fans cry. It gives him so much pain. It is the last match for his coach before retiring. All the teammates practiced hard and hoped to give their coach a perfect ending. But now, the bubble bursts (破裂).

“Is that what you want?” Mitchell asks himself.“Certainly not. But how can I change the situation? Teamwork!”Mitchell returns to reality from his thinking. He does not have a shot by himself but surprisingly passes the basketball to his teammate, Jack, who is standing near the basket. Jack catches the basketball and quickly scores a two-point shot. There goes the whistle at the same time. Perfect School finally wins the game.
