在练习的时候,我是一个不折不扣的4.5级选手。然而一旦开始比赛,我就变成了另一个人,击球绵软,大多是试探性击球,我输掉很多比赛,即使是对那些我肯定能赢或是曾经赢过的对手。每当我站在发球或接发球的位置时,就变得无比纠结,始终在想我到底该怎么打。我如何才能在真正的比赛中有所提高? When practicing, I was an absolute 4.5 player. However, once I started the game, I became another person, batting soft, mostly tentative hitting, I lost a lot of games, even for those who I can surely win or have won before. Whenever I stood at the serve or serve the ball, I became extremely tangled and always wondering how I should fight. How can I improve in real competition?
