          Youth gangs took over the slums of Rio de Janiero during the 1960s and didn't relinquish their 
          stronghold until the mid-1980s. Only a sucker wouldn't have turned to crime and this is exactly 
          how naive teen Rocket views himself. Rocket shoots all of the action with his weapon of choice, 
          a camera.

          egomaniacal owner of Globo Gym, a gleaming monolith of fitness. White intends to take over Average Joe's, and 
          Peter's non-existent bookkeeping is making it all too easy for him. The only way Peter can save Average Joe's 
          is a showdown dodgeball competition against Globo Gym.

2) 学生/班级目录

[编辑 | 编辑源代码]
a. 学校的每个班级都可以有许多学生，而每个学生可以同时注册多个班级。创建 XML 模式以捕获这种多对多关系。确保包括班级名称、容量、楼号、楼名和房间号。还包括学生的姓/名，以及他或她在班级的成绩。
b. 使用在步骤 a 中创建的 XML 模式，创建一个 XML 文档和一个 XML 样式表。您可以编造自己的数据，但请确保每个班级至少使用三名学生。
