Yoyo Witnessed a City Back on Its Feet　　
Yoyo was shocked to hear the news that a great earthquake struck the city. Ninety percent of the buildings lay in ruins， with metal pipes and taps cracking， and bricks covering the ground. There was neither electricity nor water. Many people were trapped at home and suffered agreat deal. It seemed as if the world were at an end. Fortunately， the government immediately organised rescue teams to evacuate people and arranged shelters in the open air. Ambulances whistled by and medical personnel were busy with first aid kits on hand. The helicopters delivered all kinds of supplies. Thanks to the tireless efforts and wisdom， the city began to breathe and revive. Later， Yoyo decided to learn more about how to prevent natural disasters from happening regularly， since floods， droughts， landslides， typhoons， hurricanes， tornadoes and tsunamis often strike towns and villages， causing human deaths or great damage to people's property.
