可以帮我说明怎么打羽毛球
I would really appreciate corrections to this explanation.

羽毛球规则很类似乒乓球。所有你需要的是法院，净，一球，拉奎特和一些朋友。法院是一个正方形是一样宽网和的两倍。法院必须标注由一条线，和球员必须留在该行。有两个队，每队可有1或2个的球员。第一支达到15分者胜出。车队将发球，如果对方无法回球，那么他们将获得一分。如果球队没有获胜，供应点的话，其他球队将担任。只有服务团队可以赢得点。Here is what I was trying to say:

The rules for badminton are very similar pingpong. All you need is a court,a net, a ball, a raquet and some friends. The court is a square that is as wide as the net and twice as long. The court must be marked by a line, and the players must stay inside the line. There are two teams and each team may have 1 or 2 players. The first team to reach 15 points is the winner. One team will serve the ball and if the other is unable to return the ball, then they will get one point. If the team that serves does not win the point then the other team will serve. Only the serving team can win the point.

Answer

羽毛球规则非常类似于乒乓球。所有你需要的场地，网，球，球拍和一些朋友。球场是一个长方形，宽和网长一样， 长是网长的两倍。球场需要划线，球员站在线内。有两个队，每队可有1或2个的球员。第一支达到15分​​者胜出。一队发球，对方接发球，如果对方无法回球，那么发球队将获得一分。如果发球队无法有效回球，将交换发球权，由上次接球的队发球， 只有发球的队可以得分。

这个规则已经是旧的规则了，现在执行的是每球得分制， 21 分制。
 This rule is out of date, current rule is "The first team to reach 21 points is the winner"

Answer

羽毛球规则很类似乒乓球规则。（badminton rules are very similar to the table tennis rules） 
所有你需要的是场地【It's not 法院（the Hall of Justice）。it is场地。】，球网【net】，一个球，球拍和一些朋友。球场是个正方形，它的宽度是球网宽的两倍。场地必须标注一条线，球员必须留在该线。有两个队，每队可有1个或2个球员。先得15分的队获胜。一方球队发球，如果对方无法回球，那么他们【他们refer to who serve first】将获得一分。如果先发球的球队没有获胜，扣一分【I'm not sure this sentence 】，由另一方球队发球。只有服务团队可以赢得点【I dont know how to explain this sentence】。

Answer

Lance-Lee‘s correction is good, you can use his passage if you are going to hold a badminton competetion, but if you just want to learn Chiese from this passage i dont think this is a good choice coz there are too many specialized vacabulary and the sentence structure is kind of formal which is not often used in our talking.

Answer

I think you should put this on your notebook and get corrections.
