A lot of people don't want to learn how to swim because they're afraid of drowning(溺水). Here are some simple, safe ways to avoid drowning.
Stay within a depth you can deal with. When you're first learning how to swim, don't get into water that's too deep for you to stand in. If something goes wrong, you can simply stand up and breathe.
Don't swim in bad weather condition. Swimming in a little rain should be fine, but if you see or hear a storm coming, get out of the water at once.
Don't swim in water that's too cold. Moving your hands and legs can become suddenly difficult if you're in very cold water.
Don't swim alone. Always go swimming with at least a strong swimmer. An area with a lifeguard is usually the best place to swim.
Don't swim in moving water. If you must learn to swim in an ocean or river, watch the motion(运动) of the water carefully. Make sure you're with someone who knows the situation well, and be sure to read the steps about getting out of a riptide(激流)or a rushing river.
