和老外要进行一场羽毛球比赛，比赛结束的时候应该说些什么礼貌的话好啊？

一场友谊赛完，说些礼貌的话:
It's fun.
I realy enjoy it.

我赢了:
It's a good match.
Thank you for playing with me.

他赢了:
You did a great job (or a good job).

不管你赢还是他赢,比赛完,走上前,互击手掌,然后说声"thank you!"别忘了也跟自己的搭挡说声"thank you."

我赢了
thank you
他赢了，a good job

It is fun. You did a good job.

I enjoy every minute of it.

or
I won it. Thank you for your time.

你打得很好，you do a good job.
再见：see you next.see you tomorrow.see you.
I won ,I got it.我输， I lost it.
加油，come on.
have confidence!
have fun.

for badminton: good game.
