Badminton is a racquet sport played using racquets to hit a shuttlecock across a net. Although it may be played with larger teams, the most common forms of the game are "singles" (with one player per side) and "doubles" (with two players per side). Badminton is often played as a casual outdoor activity in a yard or on a beach; formal games are played on a rectangular indoor court. Points are scored by striking the shuttlecock with the racquet and landing it within the opposing side's half of the court.

羽毛球是一种球拍运动，用球拍将羽毛球打过网。虽然可以与较大的球队进行比赛，但最常见的比赛形式是“单打”（每边一名球员）和“双打”（每边两名球员）。羽毛球通常是在院子里或海滩上进行的一种休闲户外活动；正式比赛在长方形的室内场地上进行。用网球拍击打羽毛球并将其落在对方半场内即可得分。

Each side may only strike the shuttlecock once before it passes over the net. Play ends once the shuttlecock has struck the floor or if a fault has been called by the umpire, service judge, or (in their absence) the opposing side.

羽毛球过网前，双方只能击打一次。羽毛球落地后，或裁判、发球裁判或对方（在他们缺席的情况下）宣布失误后，比赛结束。fault; a mistake made when a player is serving.

The shuttlecock is a feathered or (in informal matches) plastic projectile which flies differently from the balls used in many other sports. In particular, the feathers create much higher drag, causing the shuttlecock to decelerate more rapidly. Shuttlecocks also have a high top speed compared to the balls in other racquet sports. The flight of the shuttlecock gives the sport its distinctive nature.

羽毛球是一种有羽毛的或（在非正式比赛中）塑料的投射物，其飞行方式与许多其他运动中使用的球不同。特别是，羽毛产生更大的阻力，使羽毛球减速更快。与其他球拍运动中的球相比，羽毛球也有很高的最高速度。羽毛球的飞行赋予了这项运动独特的性质。

The court is rectangular and divided into halves by a net. Courts are usually marked for both singles and doubles play, although badminton rules permit a court to be marked for singles only. The net is 1.55 metres (5 ft 1 inch) high at the edges and 1.524 metres (5 ft) high in the centre.

球场呈长方形，用网分成两半。球场通常为单打和双打打打上标记，尽管羽毛球规则允许球场只为单打打打上标记。网的边缘高1.55米（5英尺1英寸），中心高1.524米（5英尺）。

When the server serves, the shuttlecock must pass over the short service line on the opponents' court or it will count as a fault. The server and receiver must remain within their service courts, without touching the boundary lines, until the server strikes the shuttlecock.

发球者发球时，羽毛球必须越过对方场地的短发球线，否则将被视为失误。发球者和接球者必须留在发球区内，不得触碰边界线，直到发球者击打羽毛球为止。

A let is called to end the rally [连续击球] to replay the point, the score doesn't change and the same server serves again to the same receiving player. It shall be a let, if: 14.2.7 any unforeseen or accidental situation has occurred.

Carbon fibre has an excellent strength to weight ratio, is stiff, and gives excellent kinetic energy transfer. Before the adoption of carbon fibre composite, racquets were made of light metals such as aluminium. Badminton strings for racquets are thin, high performing strings with thicknesses ranging from about 0.62 to 0.73 mm. The choice of grip allows a player to increase the thickness of their racquet handle and choose a comfortable surface to hold.

碳纤维具有优异的强度重量比、硬度，并提供优异的动能传递。在采用碳纤维复合材料之前，球拍是由铝等轻金属制成的。用于球拍的羽毛球弦是细的、高性能的弦，粗细在0.62到0.73毫米之间。grip: part that is to be gripped; handle.

A shuttlecock (often abbreviated to shuttle; also called a birdie) is a high-drag projectile, with an open conical shape: the cone is formed from sixteen overlapping feathers embedded into a rounded cork base. The cork is covered with thin leather or synthetic material.

羽毛球（通常缩写为shuttle；也称为小鸟）是一种高阻力抛射物，具有开放的圆锥形：圆锥形由嵌入圆形软木底座的16根重叠羽毛构成。软木塞上覆盖着薄薄的皮革或合成材料。

The Badminton World Federation (BWF) is the internationally recognized governing body of the sport responsible for conduction of tournaments and approaching fair play. The BWF organizes several international competitions, including the Thomas Cup, the premier men's international team event first held in 1948–1949, and the Uber Cup, the women's equivalent first held in 1956–1957. The Sudirman Cup, a gender-mixed international team event held once every two years, began in 1989. In the BWF World Championships, first held in 1977, currently only the highest ranked 64 players in the world, and a maximum of four from each country can participate in any category.

世界羽毛球联合会（BWF）是国际公认的羽毛球运动管理机构，负责举办比赛和实现公平竞争。BWF组织了几项国际比赛，包括1948年至1949年首次举办的托马斯杯（Thomas Cup），以及1956年至1957年首次举办的Uber杯（Uber Cup）。苏迪尔曼杯是一项性别混合的国际团队赛事，每两年举办一次，始于1989年。在1977年首次举办的BWF世界锦标赛中，目前只有世界排名最高的64名选手，每个国家最多有4名选手可以参加任何类别的比赛。

Badminton was a demonstration event at the 1972 and 1988 Summer Olympics. It became an official Summer Olympic sport at the Barcelona Olympics in 1992 and its gold medals now generally rate as the sport's most coveted prizes for individual players.

羽毛球是1972年和1988年夏季奥运会的示范项目。它在1992年巴塞罗那奥运会上成为正式的夏季奥运会项目，现在它的金牌通常被认为是这项运动中最令人垂涎的奖品。
