通常游泳时我们总是手脚并用,为的是能使头不时地露出水面以便呼吸,并且游得快.而当我们进行浮潜时,由于使用了潜水服、面罩、脚蹼和呼吸管等装备,就可以浮在水面头朝下看,同时不用抬头也能自如地呼吸了.动作与通常的游泳比较可以放慢很多,而且减少了手臂的划水动作,一旦你能克服用手划水的习惯,将会很快成为一位潜水员. Usually we always use our hands and feet when swimming, in order to enable the head to emerge from time to time in order to breathe and swim faster.While we snorkeling, due to the use of diving suits, masks, flippers and breathing tubes and other equipment, You can float on the water head looking down, at the same time without looking up and can freely breathe.Action compared with the usual swimming can be a lot slower, and reduce the arm’s water stroke, once you can overcome the habit of paddling by hand , Will soon become a diver.
