下午,我和妈妈打乒乓球。妈妈打球的水平很高,前几球,都是她获胜了。我在心里暗暗给自己鼓劲,准备使出全身招数,和妈妈一争高下。轮到我发球了。来个“声东击西”吧,我先把球发到左边,等妈妈把球回过来,我用力一扣球拍,把球往右边一打。不好!不知是用力过度,还是技术没有掌握好 In the afternoon, I play table tennis with my mother. Mother playing a high level, the first few balls, she won. I secretly give myself encouragement in my heart, ready to resort to the whole body tactics, compete with her mother. It's my turn to serve. To a “sound Dongxi West”, I first sent the ball to the left, so the mother back the ball, I force a snap racket, the ball a dozen to the right. I do not know is over-exertion, or technology is not good
