beaching wresting 和 BMX hiking 是什么？
好像是两种比赛项目。

beach wrestling是沙滩摔跤.你少写了一个L.

Beach wrestling
Apparently in a bid to give wrestling greater appeal to television audiences, FILA adopted beach wrestling as an official discipline during 2004–2005. Beach wrestling is standing wrestling done by wrestlers, male or female, inside a sand-filled circle measuring 6 meters (20 ft) in diameter with only two weight categories, heavy and light. The objective is to throw an opponent or take the opponent to their back. The wrestlers wear swimsuits rather than special wrestling uniforms. Wrestlers may also wear
spandex or athletic shorts.

BMX hiking: BMX是自行车越野赛.(如果写成:BMX/hiking就好理解了.)
