6 . Earthquakes usually come without warning. What should you do if this happens to you? An earthquake is dangerous, but there is still something you can do to protect yourself.

Stay calm as the earth begins to shake.

Your chance of survival in an earthquake goes up if you can keep calm. Staying calm is not easy, but it can save your life.

If you are inside when the earthquake starts, hide under a table or a bed.

You need to have something strong over your head to protect you from falling objects. Do not stand near walls or windows and stay out of the kitchen. The kitchen is dangerous because of many glass objects.

If you are outside, get to an open area as fast as you can.

Stay away from buildings and tress. If you are in a car, pull over (靠边停) to a place where there are no trees or tall buildings and stay in the car. If you are close to the sea, try to get as far away from the water as possible. Earthquakes can cause huge waves (浪) that can really harm the people nearby.

When the earthquake is over, there is still plenty of danger.

For example, fires often come with an earthquake. If you see a fire, quickly move outdoors to an open area.

Always remember to hope for the best but prepare for the worst.

9 . 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 (沙尘暴)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 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 alsotear downfarmers’ houses.

What can you do to stop sandstorms? Here’s an idea: Ask your 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.

10 . Typhoons（台风）in the northern part of the world have girls’ names. Sometimes they have very beautiful names. Rose is a pretty name but there was nothing pretty about Typhoon Rose. It was the worst typhoon to hit Hong Kong in more than thirty years.

It began to rain early on the morning of Monday, August 16^th, 1971. At ten o’clock in the morning, Typhoon Rose was still 130 miles away but already the wind was blowing people’s umbrellas away. The wind became stronger and stronger. The typhoon shelters（避风港）were soon full of boats. Ships that were too big to go inside the shelters put down more anchors（锚）. Some very big ships went out to sea. It is safer for a big ship to be at sea in a typhoon because then it cannot be blown onto rocks. Kai Tak Airport closed. No planes were able to take off or land. At 9:00 in the evening, all lights went out.

No one slept well that night. It is difficult to sleep in such bad weather.

In Typhoon Rose, more than one hundred people died. 229 people were injured（受伤）and 66 of these had to go to hospital. 1,500 people lost their homes. The people of Hong Kong will no quickly forget Typhoon Rose!
