稍微正式点的叫法都是nba world champ...随便找点冠军队的旗子看看, 大都有nba三字母.
在特定交谈场面, 可以省掉nba三字母, 直接说world champ...
泛泛而谈的场合, 讲world champ..., 那就是吹牛皮了...也有例子.
另, 早就不是官方的正式讲法. The series was named the NBA World Championship Series until 1986.
"NBA World" 的意思, 从下面句子看得很明白:
The NBA world's year-long national nightmare came to a not-so-shocking conclusion last Thursday evening as the Orlando Magic traded Dwight Howard to the Los Angeles Lakers as part of a blockbuster four-team deal.
