Unit 4 | Earthquakes
● At home If you are at home when the earthquake occurs, get immediately under the table in the living room or kitchen. Choose the biggest and strongest table you can find. You must not go anywhere near the window and don't go out onto the balcony (阳台). Once the tremors have stopped, you can come out from under the table but you must leave the building straight away.

What should we do during an earthquake? ● At school As soon as the earthquake starts, students should get under the desks immediately and wait until the teacher tells them it is safe to come out.
