25、The undersea world is very beautiful． Now more and more people want to dive in the water to find the secrets there．Scuba diving (潜水) is a new sport today． It can take you into a wonderful undersea world．

You will find many strange animals in the sea．Some are as large as a school bus．Many sea animals give out light in the dark and some have sharp teeth．

During the day, there is enough light．Here, under the sea, everything is blue and green．When fishes swim nearby, you can catch them with your hands．When you have bottles of air on your back, you can stay in deep water for a long time．However, you can' t dive too deep．And you must be very careful when you dive in deep water．

The deep sea is not an easy place to live in．It's cold, and it's dark, too．The deeper it is, the less sunlight there is．At about 3,000 feet, there is no light at all．It is very dark in the sea．Many fishes have no eyes．Some have big eyes．A few have eyes on one side．

Besides(除了) the cold and the darkness, deep-sea animals face a third danger—other animals．

Animals eat! They must find food to eat．Many animals eat plants．However, some animals eat meat．This means these sea animals have two big jobs．They need to find animals as food, and they have to try not to become other animals' meal．

21、Maybe you know floods, droughts, earthquakes, sandstorms and so on. But have you ever heard of typhoons?

  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 winds 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.
