Like many other natural disasters, floods can happen with little or no warning. Flash floods(突发性洪水) move quickly and have strong currents（水流）. They are known to bring down trees and take down buildings. Besides, floods can cause power cuts, traffic jams and other problems. But the flood itself isn't the only problem to deal with. After the flood, it may have deadly results, as it may not be easy to send food and water to the affected area.
So in the face of a flash flood, how should we save ourselves?
* Don't use bridges that rapidly-moving water is crossing, as floodwater can cause bridges to break.
* Listen to emergency broadcasts(应急广播) for more information. If you are told to move to another place, do so.
* Stay inside the car if the car is caught in the fast-moving water. Only get out if the water begins to flood the car itself, and then move to the roof of the car.
* Stay away from power lines, as they are knocked down during the strong storms.
Besides, here is something to keep in mind after a flood.
* Do not use floodwater to wash food or drink it.
* Return to your home only after the government has said it is safe to do so.
* Use only bottled or clean water for drinking, cooking and bathing.
