A. 阅读短文，选择最佳答案。
Natural disasters are powerful natural events that cause serious damage to humans, animals and the environment. They can happen quickly and bring great trouble to our lives. Every year, many places around the world are influenced by different kinds of natural disasters.
Floods are one of the most common disasters. They often come after heavy and long-lasting rain. When rivers cannot hold so much water, they overflow and cover streets and houses. Floods can destroy homes, take away crops and make people lose their things or lives. Many people have to move to safe places until the water goes down.
Earthquakes are very frightening. They happen when rocks inside the Earth move quickly. The ground shakes hard, so buildings, bridges and roads may crack or fall down. Sometimes earthquakes come with no warning, so it is important to learn basic safety rules.
Typhoons and hurricanes are strong storms with strong winds and heavy rain. They usually form over the sea and hit coastal areas. Strong winds can blow down trees and even small buildings. Heavy rain from these storms often brings serious floods.
Wildfires are common in dry areas. Without enough rain, grass and trees can easily catch fire. Strong winds help fires spread quickly and burn large areas of land.
We cannot stop natural disasters from happening, but we can learn more about them. We can follow safety advice and get prepared early. Knowing what to do when danger comes can help protect ourselves and others.
