【题目】Besides calling 120, here is what you should do when no one is around to help.

	If you get lost, you may stay where you can be seen clearly and try your best to have a rest. In a wide open area, make a colorful cross out of rocks to show where you stay.
	When you choke (噎住) at home, make a sudden hit against the back of the chair. If you can’t breathe after six tries, call 120. Leave the telephone open until help arrives.
	If you get hurt, use your hand or a scarf, or any dry cloth you can find, and push down on the wound (伤口) until the blood stops running. Don’t put the cloth around your leg tightly, or you may lose your foot.
	When a fire happens, you must move close to the floor. Cover your mouth and nose with a wet towel (毛巾), make you wet from head to foot if possible and find a safe place outside.
