There are lots of natural disasters every year. (1)
Typhoons are some of the worst storms, usually around the Pacific Ocean and the South China Sea. Most happen in July, August and September.
How does a typhoon happen? When lots of seawater gets hot in the summer sun, it evaporates(蒸发) into the air. This makes the air hotter. (2) ______ Then cooler air around it rushes in. It fills the space that is left. After the air gets warmer, it starts to move quickly, making wind. The wind goes in circles and it keeps moving higher in the sky. The warmer the air gets, the quicker the wind moves. And when wind moves faster than 30 metres a second, a typhoon begins.
A typhoon has two parts. One is called the "eye". (3)
The other part is the wall of clouds around the eye. Here are the strongest winds and heaviest rain.
Typhoons are very dangerous. In November, 2013, Typhoon Haiyan killed about 6,000 people in the Philippines. (4)
What should we do when a typhoon hits?
● Stay inside. (5)
● Try to bring all of your things inside. Strong winds could even blow away your bikes!
● Listen to the radio or TV or search on the internet for important information.
● If you're told to go to a safer place, do it right now.
A. More people were hurt and some others were missing.
B. Close all the windows and stay away from them.
C. Typhoons are among them.
D. For example, strong winds cause many problems.
E. In the eye, the wind does not move so fast.
F. When the air gets warm enough, it starts to move high up into the sky.

Floods happen when too much water covers the land. They can come from heavy rains or big waves. Floods can be very dangerous. Every year, thousands of people lose their lives because of floods.
Floods also cause many other serious problems. In 2024, more than 19 million people had to leave their homes because of floods. That's like moving everyone in a whole country, such as Somalia(索马里) or the Netherlands(荷兰). Floods can also damage roads, bridges and schools. In 2023, floods in Slovenia(斯洛文尼亚) caused damage equal to about 16% of the country's economy. In the United States, floods cost billions of dollars every year. After a flood, food can become hard to find, and dirty water can spread disease.
Floods are becoming more common, and one major reason is the rising temperature of the earth. Warmer air can hold more water, leading to heavier rain and stronger storms. Also, dry ground cannot absorb water well, so water runs quickly into low-lying areas and causes floods. Another important reason is rising sea levels, which make coastal floods worse. Large waves push more water onto the land. Scientists say that by the year 2100, major floods that once happened only once every 100 years may occur every year. Many cities could then face serious danger.
So, what can we do to deal with floods? There are some clear ways. First, we can depend on warning systems. These systems can tell people when floods are coming, so everyone has enough time to get to safe places before the disaster hits. Second, we can build sea walls to stop floodwater from spreading onto the land. Third, cities can be turned into "sponge cities" by building special streets and green spaces—these features help soak up rainwater, slow it down and reduce the risk of flooding. Finally, in some specific areas, we can carry out a plan called "managed retreat" that scientists say is the safest way. This means moving people away from these areas that flood again and again.
Floods are a big challenge. But if we work together and plan well, we can stay safe and protect our homes. By understanding the causes and taking action, we can make a real difference.
