1 How dangerous can natural disasters be? Discuss in groups.

the table.
Typhoons are strong storms with powerful winds. They usually occur in the Western North Pacific Typhoons form when warm water from the ocean meets special wind patterns. Typhoons can bring heavy rain and help cool down hot summers. However, they can be very dangerous and cause a lot of damage. During a typhoon, wind speeds can reach up to 252 kilometres per hour or even higher. This can make trees fall, damage buildings, and cause floods.
2 Read the passage and complete
the table.
Floods are huge amounts of water covering an area. They happen when there's too much rain or when rivers overflow. Floods can hurt a lot of people and destroy farms, buildings, and roads. In China, one of the biggest floods was the 1998 Changjiang River flood. The PLA troops fought against this terrible flood and protected millions of people. They successfully kept major cities like Wuhan safe.
Wildfires are big, out-of-control fires.They happen in natural places like forests and grasslands. They can badly hurt animals, plants and the environment. They are also dangerous to people living nearby. In 2023, Canada experienced many big forest fires, affecting an area of over 60,000 square kilometres.
