Water_______ from the sea

A．goes         B．comes        C．makes           D．walks

    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 wind 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.

【小題1】Which picture can tell meaning of the underlined sentences "... it starts to move higher up into the sky. Then, cooler air around it rushes in. '?

【小題2】When a typhoon comes, we cannot

As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind.

Let’s think about how this works. As wave energy passes through the water, the energy makes particles （粒子） of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn’t move forward. That’s because the wave energy just moves the water which is under the basketball.

　  So why can you see a wave knock you down on the shore？When a wave moves toward the shore, the bottom of the wave slows down because it meets the ocean floor. But the top, which is called crest(浪峰), keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action.

A．Water            B．The basketball      C．Water and wave energy   D．Wave energy

2.Match the sentences with the pictures and the right answer.
