【答案】As we all know，over the past years，floods，earthquakes and sandstorms have happened frequently.For example the earthquake that shook Tangshan on 28 July 1976 and the tsunami that crashed into coastlines across Asia on 27 December 2004.Therefore，as an individual，what should we do when a natural disaster happens？Take the earthquake for example.Relevant measures are as follows.
     First，we should know the emergency exit of the building in case we can escape to the outdoors.Furthermore，it is advised that we should stay under the solid objects with hands on heads if we cannot run out.Last but not least，it is necessary for us to learn related knowledge about all kinds of natural disasters.
     Because some natural disasters are caused by human activities，it is high time that we human did some things to change.Let's change words into action!
