| Basketball star Yao Ming is shining on the big screen, too! A film called "The Year of the Yao" has been produced. The one-and-half-hour documentary follows Yao Ming's first year in the United States. Although Yao faces cultural and language problems in his first year in America, he deals well with the stress of being an NBA rookie (新手). He finds friendship and support from others and always has confidence in himself. He is now in his third NBA season, but this season is his first playing with new Rockets forward (前锋) Tracy MxGrady who's a top player in NBA. The Rockets lost five games straight at the end of their first month and Yao has needed time to work well with MxGrady. "I haven't played as everyone expects (期待) and it has been lower than mine, too." Yao says. However, he also says that he has been trying to improve, and things are surely getting better. Things may not be easy right now, but Yao Ming is still the favorite of his fans. In the recent NBA All-Star ballot (投票), he got a record of more than 2.5 million votes from fans all over the world, which is more than Michael Jordan! |
