【小题1】When do sandstorms usually happen?

Maybe you know floods, droughts, earthquakes, sandstorms and so on. But have ever heard of typhoons（台风）?

         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.

Everyone tries to get to school on time. But when bad weather gives you trouble, can you still make it before the bell rings?

In northern China during spring, big sandstorms often make trouble for students and everyone else. When the sky is dark with sand, buses and cars all move much more slowly. Sometimes, people can’t even see for 20 metres.

Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than 10 provinces (省)  in northern China this year. More than 70 million people have had problems in those places because of the sandstorms.

People in southern China don’t have to worry about this kind of bad weather. Most of the sand comes from Gansu and Inner Mongolia（内蒙古）. In northern China, lots of places have few trees and don’t get much rain. People there have been cutting down too many trees. When there aren’t many trees, the ground can’t keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts（融化）, the ground becomes looser（更松散的）. Strong winds take the loose sand into the sky.

Sandstorms are bad for people’s health. If people breathe（呼吸） too much sand, they could cough or have asthma（哮喘）.

Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also tear down farmers’ houses.

What can you do to stop sandstorms? Here’s an idea: Ask you parents to help you plant some trees this spring.

If you see people cutting down too many trees, tell them about the dangers of sandstorms, and ask your government to stop them from cutting.
