Zone out when you serve
The best way to work on placing your serve is to use targets. I recommend that you break the service box into three zones-the area close to the center line, the portion in the middle of the box, and the part near the alley-and practice aiming for these areas. Before each practice serve, pick a zone and see if you can hit it. Some instructors use cones as targets, but I think using zones makes the exercise more realistic. Practice hitting your target zones from both the deuce and sides and be sure to hit first and second serves.
发球时分好区
规定你发球的最佳方法是使用标志物。我建议你将发球区分为3个区域---靠近中心线的区域、发球区中间的区域和靠近后场的区域---练习瞄准。在每一个发球前，选择一个区域看你能否击中它。一些教练员用锥体作为目标，我认为用区域做练习更现实。练习击中你的目标区域当平分和边时并且保证你的一发和二发。
