"泳池英语"大科普

[游泳姿势]
doggy paddling 狗刨

学游泳从狗刨开始，不需要太多技能，只要两手在胸前快速划水，稍微蹬蹬腿就行(paddle your hands quickly in front of you and kick your legs a little)。

breaststroke 蛙泳

中文以其形似青蛙游水而命名，英文只以动作命名，stroke既可以指手脚的一次划水动作，也可以指游泳姿势和游泳方式。

The "breast stroke" is when you start with your arms together in front and draw them back in a wide circular motion.
蛙泳就是两臂在胸前伸直，然后画一个大圈划水的泳姿。

backstroke 仰泳

仰泳的动作用英文可以这样解释：

The "backstroke" is when you float on your back and swing one arm at a time up over your head, then pull it down toward your body again through the water.
仰泳就是仰面浮在水上，两臂轮流向后划水的泳姿。

crawl 爬泳、自由泳

自由泳是最快的游泳方式。

When you swim in a crawl, you face down into the water and swing one arm at a time up past your shoulders, then pull it toward your body through the water.
自由泳时，脸朝下在水中，两臂轮流划水前进。

tread water 踩水

"Treading water" means moving your hands and feet around so that you don't sink.
踩水就是在水中手脚画圈蹬踩，保持身体不沉。

[游泳安全]
lifeguard 救生员

一些泳池和海滩会有救生员执勤(have a lifeguard on duty)，他们在水边看护，保障游泳者的安全。

游泳池通常还会贴着一些警示条例，比如：

Swim at your own risk.
在此游泳风险自担

也就是说如果你受伤或者溺水，游泳池管理者概不负责。

Children under twelve must be accompanied by an adult.
12岁以下儿童须有成人陪伴

No running on the deck.
请勿在泳池边奔跑

No horseplay.
请勿打闹

所以在游泳馆里，你不可以故意把水溅到别人身上(splashing people)、追追打打(chasing someone)、在水里打架(wrestling in the water)、把人扔进水里(throwing people in the pool)等。
