撞人犯规(charging)：进攻队员撞到没有动作的对手的违例情况。

Charging: A violation in which an offensive player runs into a stationary opponent.

拖手（trailer）：进攻队员拖住第一个快攻，但是经常是在第一轮防守过后以好位置投球得分。

Trailer: An offensive player who trails on a fast break but often is in good position to score after the first wave of defenders goes by.

举个例子。这儿有两个进攻队员和两个防守队员，他们准备开始实施挡拆。

So, here's an example. There are two offensive and two defensive players, getting ready to do the pick-and-roll dance.

比赛的核心是：进攻方一名队员不顾一切进入对方半场，碰触尽量多的对方队员从而得分；防守方则使尽浑身解数，通过团队合作捉住进攻队员。

The core idea of the game is to score points by raiding the opponent's court and to touch as many defensive players as possible without getting caught on a single breath.
