本文摘自SOHU,向大家推荐一下:
如果告诉你,世界上飞行运动速度最快的球是羽毛球,你会相信吗?不管你信不信,这都是事实,根据科学计算,羽毛球的离拍速度最高可达到每小时180英里,约合288公里的时速,所以与这样的速度相比,即便速度最快的网球发球或者在棒球职业联赛中用最大力气投掷的棒球就像是一个慢动作画面。

Yes, thanks X. No problem, I can make it definitely. If anyone else wants to play with us on Saturday, just come and meet us at Metro guy-concordia at 8:45 am. And you'd better leave your message here first.
