You might even need to leave your home with little warning. But disasters don’t have to surprise you. Plan before something bad happens. Hold a family meeting. Discuss the types of disasters that could happen. Then plan a way to make your family be with each other if they get away. Choose two places for everyone to go to if it isn’t safe to return home. The first should be near your house. You can go there in a very dangerous situation like a fire. The second meeting place should be outside your neighborhood. This will give your family a place to come together if you must evacuate(疏散撤离). Next, choose a contact (联络) person outside your area. After a disaster, it is often easier to exchange information or talk with other people over a long-distance call than a local one. A contact person can pass messages between family members if they can’t meet or get in touch with each other. Then create a family disaster work-box. It should include everything your family needs to survive for at least three days. Place your tools in a bag, so you can carry it if you need to evacuate. When getting ready for it, remember that different people have different needs, including special items necessary for not only elderly but young members of your family.Are you 1. for the worst?Planning for the worst● Discuss the different types of disasters.● Try to make your family 2. if they get away from each other.● Choose a contact person to pass messages and 3.with each other over a long-distance call.4. to survive● Create a family disaster tool box including something like food and water.● Remember to get special items for 5.old and young people in your family.
