Earthquakes， typhoons(台风) and floods are common natural disasters that can cause terrible damage(破坏)and bring serious threats(威胁)to safety. Earthquakes suddenly shake the ground， often without warning. To stay safe during an earthquake， people had better “Drop， Cover， and Hold On” until the shaking stops. You can find a strong table to hide under and hold on. 课堂 训练Typhoons， known as hurricanes or cyclones in other parts of the world， can lead to strong winds and too much rain. Before a typhoon arrives， storing necessary things like food， water， and batteries is important. Floods can happen when rivers run over because of too much rain. To prepare well， avoid building homes in the areas where floods often happen and place important electrical appliances(电器) up off the ground in your home. Having an emergency plan is also a must. By understanding these disasters and taking action， communities and people can reduce the risk of harm and recover(恢复)more quickly after disasters happen. 课堂 训练1.
