Unit 4 Earthquakes

　　An earthquake is one of the most common natural disasters(灾难).So it is necessary to learn some simple safety tips to protect yourself or your family members.

　　Some things like those made of glass are easily broken and should usually be placed on a lower surface，near the ground instead of placing them in the cupboards higher up.Never place them near your bed，sofas and other furniture where you would be sitting or lying down.When there is a strong movement，these pieces will fall on the floor directly and not on you.

　　There is a strong chance of short circuits(短路) and fire during an earthquake.Make sure you turn off electrical(电的) connections and gas immediately when an earthquake happens.

　　During an earthquake，lie beneath(在......下面) an object that is not easily broken.Do not go near objects that could directly fall on you.Never use the elevator to go down.Stay inside until the shaking stops and it is safe to go outside.Research has shown that most injuries happen when people inside buildings try to go out.Use the staircases at all times.

　　If you are outdoors，do not take shelter under a tree，streetlights，or tall buildings.If you are driving，stop your car and stay in a safe place.Do not park your car under a tree or any tall object.
