To Rescue a Drowning Person   

     Don't jump in to save a drowning person unless you are a trained lifesaver. The victim may pull you under.   

     Instead, try to toss (抛) a life preserver if you have one. Anything that will float can save the person's life.

A beach ball, a vacuum jug, or a picnic chest will also help. The National Safety Council points out that many

drowning could be prevented if people knew all the common objects that float well enough to help a drowning

person.   

     If you are in a boat, or you can find one, use the boat to try to reach the person in trouble. Turn the boat

so the victim can grab the stern. Don't stand up to help the victim. Stay seated so the boat won't overturn. Try

to balance the boat as the person climbs aboard. If the boat overturns, stay hanging on to the side for a while

to relax before trying to right it.
