     Would you know what to do during a big earthquake (地震)? Scientists have some advice for us.

     If the ground begins shaking while you are driving, stop your car on the roadside and stay in it. If you are

in a tall building, don't use the lift and never jump out of the windows. When you are in a living room, find a

strong table or rush into a smaller room like washroom. Then lie down your body. Take care of your head.

When you are in a public place, like supermarket or cinema, don't crowd in jam (拥挤), or you may fall over

and get hurt. Cross your arms to protect yourself. You can also find a place to hide.

     After the main shake, quickly run out of the dangerous building for there will be small earthquakes. If you

are safe, remember not to engage the phone line, keep it free for rescue (援救) using. Don't go to the hospital

if you are not badly hurt, others will really need help. Take part in the rescue action if you can.
