[导语]地震是最常见的自然灾害之一ꎬ常
造成巨大的损失ꎮ 如何在地震中保护自己及家
人呢? 本文就此提出了几则忠告ꎮ
An earthquake is one
of the most common natural
disasters. It may cause
great damage. So it is wise
to learn some simple safety
tips to protect yourself or your family members.
Fragile itemsꎬ like those made of glass are
easily broken and should usually be placed on a
lower surfaceꎬnear the ground instead of placing
them on cupboards higher up. Never place them
near your bedꎬsofas and other furniture where you
would be sitting or lying down. When there is a
strong movementꎬ these pieces will fall on the floor
directly and not on you.
There is a strong chance of short circuits(短
路)and fire breakouts during an earthquake. Make
sure you turn off electrical connections and gas
immediately when an earthquake happens.
During an earthquakeꎬ lie beneath an object
that is not easily damaged. 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
(楼梯)at all times.
If you are outdoorsꎬ do not take shelter under
a treeꎬstreetlightsꎬ
