Now let me tell you how to survive an earthquake.When a serious earthquake takes place，we should hide in a bathroom or under some strong furniture immediately.At the same time we’d better fall on the ground and close our eyes with a towel on our nose and mouth to stop the dust.If possible，please turn off the gas stop and the electric power switch.But you mustn’t try to run out or jump off a building.And do remember not to use the elevator.That’s all.Thank you！。
