01
也叫持球掩护 · 有球掩护 · on-ball screen · pick
挡拆掩护是给持球人做的掩护：掩护人站到防守持球人的那名球员旁边把他挡住，持球人从掩护的另一侧突出去。 · A ball screen is set for the player holding the ball: the screener plants beside the on-ball defender so the handler can drive past on the other side.
什么时候用 · When it is used想给持球人一条突破路线或一次从容出手时用。防守选择换防、绕过还是挤过，决定了这一回合接下来是顺下、外弹还是分球。 · Used to give the ball-handler a lane or a clean look. Whether the defense switches, goes over or goes under is what decides if the play becomes a roll, a pop or a kick-out.
02
背掩护Back Screen
也叫背后掩护 · back pick
背掩护做在防守人的背后：掩护人挡住他的退路，被掩护的队友因此可以趁他背对切入路线时直接切向篮筐。 · A back screen is set behind a defender, blocking the way they would retreat, so the teammate being screened for can cut straight to the basket while that defender's back is to the cut.
什么时候用 · When it is used防守人正盯着球、背对着切入路线时最有效。UCLA 切入整套就是建立在这一道掩护上的。 · Most effective when the defender is watching the ball with their back to the cutting lane. The UCLA cut is built on one.
03
也叫向下掩护 · 底线上提掩护 · down screen · pindown · screen down
下掩护朝端线方向做：掩护人从高位下沉去挡住防守人，位置更低的队友借这道掩护上提到侧翼或弧顶接球。pin down 和下掩护说的是同一个动作。 · A down screen is set toward the endline: the screener drops from up top to block the defender so a teammate below can come up to the wing or the top and catch it clean. A pin down is the same action under a different name.
什么时候用 · When it is used给射手创造接球投篮空间最常用的一种。球在弧顶或侧翼时，底线附近的人靠它上来拿球。 · The usual way to free a shooter for a catch. With the ball at the top or on the wing, the player near the baseline uses it to come and get the ball.
04
也叫外弹跑位 · 闪出掩护 · flare
外弹掩护的方向和常见掩护相反：接掩护的人不朝球跑，而是朝远离球的一侧弹出到外线空档。 · A flare screen faces the opposite way to most screens: the receiver does not cut toward the ball, they flare away from it into space on the perimeter.
什么时候用 · When it is used防守人抢到掩护的球侧、准备封死朝球那条路线时，往反方向弹出就是空位。 · When the defender jumps to the ball side of the screen to deny the usual cut, flaring the other way is open.
05
横掩护Cross Screen
也叫横向掩护 · cross pick
横掩护横穿禁区做，通常在低位：一名球员横过来给另一名挡人，让队友换到自己想要的那一侧要位。 · A cross screen is set across the lane, usually low: one player screens across for a teammate, who uses it to seal on the side they want to receive on.
什么时候用 · When it is used想把内线换到弱侧要球、或者把防守人挡在身后不让他绕前时用。 · Used to move a post player to the side they want the ball on, or to leave a defender behind rather than in front.
06
也叫反向掩护 · 远离球掩护 · screen away · away screen
远离球掩护是传球之后不追球，转身去给另一侧的无球队友做掩护。 · Screening away means the passer does not follow the ball. They turn instead and set a screen for an off-ball teammate on the other side.
什么时候用 · When it is used传切进攻里最基本的一条连接：球往一边走，人往另一边动，防守没办法同时看住两处。 · The basic connector in motion offense: the ball goes one way and the players go the other, so the defense cannot watch both.
07
也叫交错双掩护 · 连续下掩护 · stagger · double stagger
连续双掩护是两名（或更多）掩护人前后排开，同一名队友接连借这两道掩护跑出来。 · A stagger is two screeners (or more) set one behind the other, with the same cutter using both in sequence.
什么时候用 · When it is used一道掩护挡不住的射手，就用两道。防守人挤过第一道，往往就赶不上第二道。 · For a shooter one screen cannot free. A defender who fights over the first is usually late to the second.
08
也叫电梯门掩护 · 关门掩护 · elevator doors · gate screen
电梯门掩护是两名掩护人先分开站，等队友从中间穿过的一瞬间并拢，像电梯门一样把追防的人关在门外。 · An elevator screen has two screeners stand apart and then close together the moment the cutter passes between them, shutting the chaser out like a lift door.
什么时候用 · When it is used专门用来甩开那种绕过一切掩护死缠不放的防守人。 · Built for the defender who chases through every screen rather than switching.
