This article is going to cover the basics of setting great screens during the course of a game. It will cover some of the basics, teaching points, and cover the four basic types of screens that most players will encounter throughout the course of a game.
这篇文章将要讨论的是如何在比赛中做出优质的掩护。它包含许多掩护的基本方式、技巧和大多数运动员都会在比赛中面对的四种基本掩护。

Getting Set
准备工作
The first thing that you need to focus on when setting a screen is making sure that your feet are set and that you aren't leaning to one side or the other. If your feet are moving or you lean into your screen, you may get called for a moving screen and an offensive foul.
做出掩护的第一件事就是需要确保稳定的站位，身体不能偏向两侧，如果你的脚正在移动或者身体偏向你的掩护方向，你可能被吹移动掩护或者进攻犯规。

Stance and Angle
站位和角度
The next thing that you want to focus on is getting low and wide on your screen and choosing a great angle. Doing both of these things the right way will drastically increase the outcome of the screen and hopefully open up a great scoring opportunity for your team.
掩护的下一件事便需要你两腿叉开身体重心尽可能的低并且选择一个良好的角度。做好这些步骤会极大的提升掩护的效果，为你的球队带来得分机会。

Screening to Score
挡拆后得分
A screen is used to help get a teammate open, but can also result in the person setting the screen getting open as well if the defense over helps on the player using the screen.
一次挡拆往往会帮助你的队友拉开空间，如果被掩护者受到防守也会为掩护者创造空间。
That is why after setting a screen, you want to react and be ready to get the basketball. Some examples would be, opening up and spacing for the shot, rolling to the basket for a finish, or immediately going to set another screen. You should always be doing something after you set a screen; don't ever just screen and stand.
这就是为什么当你完成一次掩护，你便做好接球的准备。有的是拉开空间后投篮，有的是切入篮下终结比赛，还有可能为下一次的掩护做准备。总之，挡拆后你需要做点什么而不是站在那里不动。

Basic Types of Screens
掩护的基本类型
Here are 4 basic types of screens that you can use the next time you play. Also included with each type of screen is a link to watch a play with that type of screen in it.
这里有几种不同的掩护会给你的队友扯开空间。有的复杂有的简单，但是良好的掩护会让球队的进攻变得更加流畅。每支球队都需要有队员为其他队友做出掩护。下面是你可以在下次比赛中使用的4种掩护方式。
Ball Screen: A great ball screen is set with pace and at a good angle. The reason why you want to set it with pace, is because if you can get your defender trailing you before you set the screen, they will be out of position to help on the screen.
有球掩护：一次优秀的有球掩护既需要速度也需要角度。需要速度的原因是能把防守者挡在你身前，从而使他们在防守中失位。
Down Screen: You will most likely use this type of screen for a wing player. What you are going to do is position yourself away from the ball next to the player that is going to use the screen. From there the wing player is going to run off of you and use you as a screen.
下掩护：你常常会为你的侧翼球员做出这种类型的掩护。你需要做的就是站位在接球队员的一侧，这样侧翼球员就可以通过你这个屏障来摆脱防守队员。
You still have the responsibility to screen the defender. The terminology is called "head hunting" and it is important that you legally screen the defender. Secondly, you need to make sure that you are reading the type of cut the wing player is making, and then determine whether you should space, roll, etc. As a general rule of thumb, if the wing player curls you want to space, and if they straight cut or fade cut you can roll or slip the screen.
你的职责就是挡住防守者。这个术语叫做“猎头”，同时合法的掩护住防守队员也是很重要的。第二，你需要阅读出侧翼球员的切入方式，然后决定是拉开空间、切入篮下，等等。通常，如果侧翼球员来通过你绕掩护，你需要扯开空间，如果侧翼球员直接切入或者底角远投，你就需要拆开挡拆或者切入篮下。
Back Screen:The back screen is a great way to set up your teammates for easy finishes at the basket. A big key to this type of screen is angle. You need to set up your teammate so that they have a great lane to the basket for the finish. Once you set the screen you need to open up to the ball. If you set a great screen and your defender helps on the screen you will be wide open, but only if you open up and make yourself a target.
背掩护：背掩护可以使你的队友轻松的在篮下得分。这种类型的掩护的一个重要诀窍就是站位的角度。你需要为你的队友站好位置，这样他们便可以有突入篮下的良好路线。一旦你进行掩护，你需要拉开空间。如果能成功够做一次这样掩护，你的防守者过来进行防掩护的话，你就会有广阔的空间，但是只有在你有空间的时候，才可以进行这种掩护。
Flare Screen: This is similar to the back screen but the only difference is the angle of the screen. Instead of screening them so they can cut into the paint, you are going to screen them so that they can cut along the perimeter for a shot.
后掩护：这种方式的掩护和背掩护相似但是掩护的角度不同。背掩护是使队友切入到油漆区，而后掩护时，队友则会绕到三分线外投篮。
This is a great way to take advantage of help defenders that get caught ball watching. Once again though, you need to open up and make yourself a target immediately after you set the screen because you may be open for a shot.
这是能使防守者陷入看球不看人的防守方式中，一旦出现这种机会，你需要在掩护完成后拉开空间，因为你可能会有投篮的机会。

Conclusion
结语
Setting screens in basketball is a big part of the game. It is not something that requires a lot skill, but it does require knowing how to execute the move correctly and then having the desire to do it. To become a great screener you must make a conscious effort.
掩护是篮球比赛中一个重要的部分，但不需要许多高超技巧，但是需要作掩护者能够正确的执行动作和有做掩护欲望。想要成为一名掩护高手，你必须有意识的进行努力。
