星期日，我和刘xx去了xx公园打羽毛球，我们先把球袋打开把羽毛球拍和羽毛球拿出来。
On Sunday, Liu XX and I went to XX park to play badminton. First, we opened the bag and took out the badminton racket and badminton.
比赛正式开始了首先是我发球我决定发一个高空球，说干就干我发了足有两层高的高空球可是刘逸凡用反挡当住了我的球，球以飞快的速向我飞来。我使劲一打球又飞了过去这样打来打去渐渐的太阳下山了。
At the beginning of the game, first of all, I decided to serve a high-altitude ball. I said that I could serve a two-layer high-altitude ball, but Liu Yifan caught my ball with a counter block, and the ball came to me at a fast speed. I tried hard to play the ball and fly in the past, playing like this and gradually the sun went down.
这是美好的一天。
It's a good day.
