I like the indoor sports venues, because I like the sport is badminton, set up in indoor.

我喜欢在室内场所运动，因为我喜欢的运动项目是羽毛球，设立在室内。

After the implementation of the new rules in badminton, a set of leading accumulated before vanished, while the contingency and unpredictability of race increased significantly.

在羽毛球新规则实施之后，以前积累的一整套领先世界的经验荡然无存，比赛的偶然性、不可预测性明显增加。
