On April 20th,, a big earthquake hit Ya’an, Sichuan. Nearly 200 people died. Many people were hurt. Why do earthquakes happen?
The surface(表面) of the earth has many pieces. These pieces are always moving. When two pieces move past each other, there is an earthquake.
Scientists are working hard to find out more about earthquakes. They try to predict(预测) them, but it’s very hard.
Do you know how to get ready for an earthquake? Do you know what to do during an earthquake? Here are some things you should know.
What to do before an earthquake
Make sure you have two bottles of water, a packet of biscuits, a clean towel , a few band-aids（创可贴）, a radio and a flashlight（电筒）at home.
What to do during an earthquake
If you are inside:
★Stay where you are. Quickly move under a strong desk, or along a wall. This will protect you from falling things.
★Don’t stand near windows.
★Turn off the lights.
★Don’t get into a lift during an earthquake. If you are in a lift, get out quickly.
If you are outside:
★Don’t stand near buildings. Things may fall on you.
★Lie on the ground until the shaking stops.
