Earthquakes can be very scary（吓人的）. But you need to keep your mind stable (坚定的) in order to make sure you are safe. Be calm and try not to run here and there.

If you manage to come out of your house, go to an open space like a garden or a park where you will be a lot safer. If you live quite some floors above in your building, try to find a place near a bulky(坚固的) object such as a bed. Curl up (蜷缩) and sit on the floor and make sure you are not near a window, fireplace, gas stove and so on. Remember don’t use lifts or escalators.

Some people say you should stand on a doorway. That is not true. If the doorway jambs (侧壁) are weak, they might fall on you. Also if people want to pass through that door, you may stop them. Leave all doorways free.

Another important thing to keep in mind is that you mustn’t climb down the stairs during an Earthquake. If the tremors (震动) stop, after a few seconds, just climb down the stairs as quickly as you can and move out of the building, but don’t run.

Earthquakes usually destroy gas pipes and electrical wires. Turn off the main gas. And don’t light candles or lighters and create an even bigger disaster.

If you’re driving and feel a shake, stop your car at the side of the road and get out. Make sure you are not on a bridge. Bridges and overhead roads (高架路) have the biggest danger of falling.

1. The best title for the passage should be________.

2.When an earthquake suddenly happens, you should       .

a. remain standing near a window             b. turn off the main gas

c. stay in an open space                     d. stand on a doorway

e. keep off  overhead roads

3. Which of the following is NOT true, when an earthquake suddenly happens?

4. It can be learned from the passage that________.
