　　Passage 1

　　Chinese basketball players have never been so close to the NBA before, but questions remain about how they will adjust to life in the NBA if they go. Wang Zhizhi, the 2.16-metre center for the Bayi Rockets who was chosen by the Dallas Mavericks two years ago, has finally received permission from authorities to travel to Dallas to play for the rest of the NBA season after he finishes playing in the Chinese Basketball Associations finals on March 25th. If he has no problems with his visa, Wang will be the NBA’s first Asian player. Wang was chosen by the Mavericks in the second round of the 1999 draft, but the Rockets, an army-run club, refused to let him go. After negotiations between the Rockets and NBA representatives, the decision was made to allow Wang the chance to try his hand at American basketball, but only for a short period of time. He has to be back to play in the Ninth National Games in November in Guangzhou. Another center who has attracted attention from the NBA is Yao Ming, the 2.25-meter star who has led the Shanghai Sharks into the final fight with the Rockets this year. The 20-year-old’s NBA dreams might be harder to realize. Yao is the center of the Sharks and the club’s manager Bei Genyuan has said that he would allow Yao to go only at a proper time, for a proper team and under proper conditions. Yao hasn’t been chosen yet and it is unlikely that he will be any time soon. People in the Shark’s front office earlier told members of the press that “it is not proper for Yao to attend the draft this year” because he has to represent Shanghai in the Ninth National Games. Even if Wang and Yao make it to the promised land of basketball at last, analysts on both sides of the Pacific have said the NBA road will be a long one for both of them. Besides needing to work on their upper body strength, Wang and Yao will also have to adapt to the speed, techniques and above all, culture of the NBA.
