爸爸教孩子游泳,戴上泳镜,孩子小心翼翼地把着池边。爸爸说:“我们不用浮力板,也不用手扶池边蹬腿。我们先学张嘴,就像河马那样张大嘴巴。”张嘴很简单,会张嘴就会游泳。比如仰泳,先把头埋入水里,抬起头,赶紧脸朝水面张大嘴巴。“为什么要脸朝水面?”孩子问。“从水里抬起头来,头上的水会顺着脸向下流。脸朝水面,水就不会流进鼻孔和嘴巴里。记住,游泳的时候,鼻子一点儿作用也没有,是个累赘,一定要把鼻子‘关上’。”爸爸回答。 Dad taught children to swim, put on swimming goggles, children carefully with the pool edge. Dad said: “We do not need buoyancy plates and do not have our hands on the edge of the pool .We first open our mouths and open our mouths like a hippopotamus.” “Open your mouth and swim with your mouth open. Such as backstroke, the first head buried in the water, looked up, quickly opened his mouth wide mouth. ”Why face to face?“ ”The child asked. “When you look up from the water, the water on your head will flow down the face, and when you face the water, the water will not flow into the nostrils and mouth. Remember, when swimming, the nose does not work, Tired, make sure your nose is ’closed.’ ”Father replied.
