体育英语|网球小白第一步：闭眼放松练发球！

Dear friend, please followus to begin Play Tennis and know how to playit step by step:
Part I
1. Eyes shut
once you've developed a sound service motion, it's important that you toss the ball into the same spot each and every time. You should be able to serve with your eyes closed, because the ball should be in the same spot every time.
2. Knock Knock
The key to having a powerful serve is in creating a loop in your backswing and letting your racquet head drop behind you as you toss the ball. This lengthens^{1 the swing, and more length means increased power. Serving requires using the big muscles of the body. Ask Pete Sampras, Boris Becker, or Goran Ivanisevic where their power comes from and they'll say their legs, hips2, and shoulders.
3.Same as it ever was
When you're practicing your serve, go through the same pre-serve rituals you use during a match. Bounce the ball a few times, bring your hands together, and then come to the set position. It doesn't matter if you hold your hands high or low, or how many times you bounce the ball; just do it the same way you would in a match, every time. The idea behind practice is to create consistency3 through repetition. If you don't practice your rituals, they won't be worth employing during a match.
4 Power plays
Looking to add more power to your serve? Here are two things you need to do:
1) Stay relaxed. When trying to hit the ball hard, most players tend to tighten4 up. Try to keep both your arm and your hand loose.
2) Don't be afraid to use your entire body. Turning your hips and shoulders and getting more leg drive into your motion will add power to your serve. The one thing you can't afford to do is only use your arm. The whole body needs to be part of the service chain.
网球小白第一步：闭眼放松练发球！
1、 闭上你的眼
一旦你形成了好的发球姿势，那样要做到每一次都将球抛到相同的地方，这一点很重要。每次发球的时候，你都可以把双眼闭上，由于每次球都要落在相同的地方。
2、 击球、 击球
要发出有力的球重要在于在击球前尽可能把手臂轮成圆圈，抛起球后，把球拍举到头的后方。如此会增大挥拍的幅度，幅度越大，击球的力量也就越大。发球的时候应该用身体的大肌肉群。问一问桑普拉斯、贝克尔或伊万尼塞维奇他们的力量是从何而来？他们会说是从他们的腿部、臀部和肩部而来。
3、 一如既往
当你练球的时候，每次都要做在相同的预备发球动作，就象每次比赛之前所做的那样。拍击几次球，双手同时举起到预备姿式。无论你的手举得是高是低、拍了多少次球都没关系，只须象你每次比赛之前所做的那样，每次都如此做。这是为了通过动作的重复来培养一种好习惯。假如你不重复训练相同的动作，那样在比赛中你就没办法运用这类动作。
4、 大力击球
你是不是也期望能发出更有力的球？那样你需要遵循以下两点：
1）放松。在大力击球前，多数球手都会把肌肉绷得非常紧。你应该尽可能叫你的胳膊和手放松。
2）要用全身的力量。转动你的臀部和肩部，增加腿部的蹬力，如此在击球时才能获得更大的力量。不可以只用手臂的力量。发出优质的球需要身体的每个部分都协调发力。}
