Safety is very important to everyone． As a teenager， do you know how to protect yourself in different situations？

If there is a warning sign near the water， don't go into it． Only swim in the area where there is a lifeguard． Never swim alone． When you see someone drowning（湖水）， never jump into the water if you can't swim． Remember to ask adults for help in time． When you go boating， you must wear a life vest（救生衣）．

Some strangers may give you snacks or other things to show kindness． They may also invite you to his or her home， offer you a ride， or ask you for detailed information about you or your family． Say no to themand leave as fast as you can． If you find yourself in danger， shout "Help!" loudly or find out a safe way to get help． The strangers around you， such as the police a security guard（保安）， a shop assistant or even a passer ﹣ by can help you．

Stay away from places that are very crowded． Once you go， watch out your feet and avoid falling down． When people around begin to push， try to stand sill and never push harder． If you fall down in the moving crowd， cover your head with both hands． Lean（倚靠） to one side， and curl up（蜷起） your body．
