如何打网球
1. Eyes shut
1、闭上你的眼
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.
一旦你形成了良好的发球姿势，那么要做到每一次都将球抛到相同的位置，这一点非常关键。每次发球的时候，你都可以把眼睛闭上，因为每次球都应该落在相同的位置。
2. Knock Knock
2、击球、击球
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 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, hips, and shoulders.
要发出有力的球关键在于在击球前尽量把手臂轮成圆圈，抛起球后，把球拍举到头的后方。这样会增大挥拍的幅度，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. Same as it ever was
3、一如既往
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 consistency through repetition. If you don't practice your rituals, they won't be worth employing during a match.
当你练球的时候，每次都应该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、拍了多少次球都没有关系，只要象你每次比赛之前所做的那样，每次都这样做。这是为了通过动作的重复来培养一种良好习惯。如果你不重复练习相同的动作，那么在比赛中你就无法运用这些动作。
4. Power plays
4、大力击球
Looking to add more power to your serve? Here are two things you need to do:
你是否也期望能发出更有力的球?那么你必须遵循以下两点：
1) Stay relaxed. When trying to hit the ball hard, most players tend to tighten up. Try to keep both your arm and your hand loose.
1)放松。在大力击球前，多数球手都会把肌肉绷得很紧。你应该尽量让你的胳膊和手放松。
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.
2)要用全身的力量。转动你的臀部和肩部，增加腿部的蹬力，这样在击球时才能获得更大的力量。不能只用手臂的力量。发出高质量的球要求身体的各个部分都协调发力。
