Maybe you know floods, droughts, earthquakes, sandstorms and so on. But have ever heard of typhoons（臺風(fēng)）?
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 sea water gets hot in the summer sun, it evaporates into the air. This makes the air hotter. When the air gets warm enough, it starts to move higher up into the sky. 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 the wind moves faster than 30 meters a second, a typhoon begins.
A typhoon has two parts, One is called the “eye”. In the eye, the wind does not move so fast. The other part is the wall of clouds around the eye. This is where the strongest with and hardest rains are.
Typhoons are very dangerous. In 2004, Typhoon Yunna killed 164 people in Zhejiang, and 24 people were missing. In May 2006, Typhoon Pearl hit Guangdong and Fujian, and thousands of houses were damaged.
What to do when a typhoon hits:
Stay inside, Close all the windows and stay away from them.
Try to bring all of your things inside. Strong winds could even blow away your bikes!
Listen to the radio or TV for important information.
If you’re told to go to a safer place, do so right away.

A．in the hot seasonB．in the cold season

If you want to watch and know something about birds, you must find a good place near the bird nest（巢）.
Birds sit on eggs and take care of their babies from April to June. Because the baby birds are too young to leave the nest, parents often go to look for food and come back in several minutes. So it is good to watch birds. When we watch birds, we’d better hide ourselves in a close place to the nest, and it’s better to use binoculars(雙筒望遠鏡).
