游泳—Swimming

My kids are taking swimming lessons now at a local swimming pool. The lessons first teach kids how to not be afraid of the water by learning how to put their face under the water and holding their breath for a few seconds. Next, the lessons teach children how to float on their backs. Later on, kids learn how to do some of the basic strokes including freestyle, breast stroke, and backstroke. Learning how to do these takes time, practice, and patience. Kids also need to learn how to tred water, and in some water safety classes, instructors¹ teach people how to tie up the legs of their pants to make a flotation device. Kids can also learn how to dive of the side of the pool or from the diving board. If kids pass off the requirements for their class, they receive a certificate of completion.
