A group of senior high school students are playing outside on a basketball court. They are shouting with excitement. And they all have the same dream. They wish to play in the NBA, just like Huston Rocket's Yao Ming. "Someday, there will be more Chinese players like Yao in the NBA," said 15-year-old Xie Tao, a senior 1 boy at Shanghai No. 2 Middle School. Xie always watches Yao playing on TV. "He is a great player. He makes me proud to be Chinese," he said. Like Xie, 17-year-old Liu Yan at Beijing No. 22 Middle School is also a big NBA fan. "Since early May, I've not missed one game in the NBA," said the senior 3 student. Basketball is becoming popular in middle schools across the country. And more young players are starting to like the sport. More students are playing the game. Jiang Hui, a basketball teacher at Beijing No. 2 Middle School, said that 85 percent of the students at this school like the sport. "Students are full of passion for the game," Jiang's team won the regional first prize in the 2004 National High School Boy's Basketball League in   march. The league is the first national basketball competition for high school students. Playing basketball is a good way to exercise. But students also enjoy it for other reasons. For Li Yan, a Senior 2 at Shanghai No. 12 Middle School, basketball teaches him lessons in life. "When I am in a game, I feel more confident about my studies, " he said. " It also teaches me to have a good team spirit and to enjoy friendship." How many students are mentioned in the passage?
