What to do in an earthquake
Earthquakes always happen suddenly, so it is difficult to warn people about them. Usually people have little or no idea about what to do during an earthquake, so here is some advice:
Inside
1 Do not jump out of high buildings.
2 Hide under a table. Stay away from windows and
heavy furniture. Keep clear of fire.
3Leave the building quickly when the ground stops
shaking, but do not use the lift.
3 Read the passage and check your answer to Activity 2.keep clear of sth.
清除；摆脱；没有；不接触4 Keep calm, especially when you are with other people. Be brave and be helpful.
Outside
1 Move away from buildings, because parts of a building may fall on you.
2 Do not stand near street lights or under power lines.
3 Stay away from bridges and trees. If you are in a bus or a car, stay in it.
4 In the mountains, be careful of falling rocks.
5 On a beach, run away from the sea and more quickly to higher ground.
In short, follow what you learnt in school. You can be
safe and you can also help save others. 4 Read the sentences. Decide if the
following actions are right (√) or
wrong (×). When the earthquake started…
1 …I hid under a table.
2 …Sam sat on his desk.
3 …Alice ran out of the building.
4 …Peter and Helen stayed in their car.
5 …my family and I moved away from the beach.
