Preparation can protect us from being victims of a natural disaster. To prepare for a tornado, firstly we have to learn the signs of a tornado so that we can know that there will be a tornado. The signs include a dark, greenish sky; large hail; dark, low clouds; and loud roaring sounds. During the tornado, we should go to the safe places in our house and get away from the window because the windows can be broken into pieces by the tornado and people can get injured if they are close to them. More importantly, we should lie down and cover our heads with our hands to avoid being hit into our heads. After the tornado, we should get away from any damage and listen to the news.
