Full-court press: a very aggressive defensive strategy in basketball game in which the defense team pressures the offense opponent player-to-player in order to disrupt dribbling or passing. In business world, it usually is used to describe all-out effort.
这个常用口语来自于篮球比赛中的“全场紧逼”这一战术语。当一个防守队采用全场紧逼战术的时候，这个球队紧紧跟防对方每个球员，阻止和破坏他们带球和传球，为对方造成很大压力。这种战术很消耗球员体力，所以一般是别无选择的时候，或者为了暂时打乱对方阵脚的时候才使用。在商业中，这个常用口语通常用来形容很大的努力。
造句：
a). If we want to submit the report by tomorrow, we have to make a full-court press on it now.
b). Suddenly behind by eighteen points, the coach asked the team to do a full-court press.
