As a youngster,there was nothing I liked better than Sunday af?ternoons on my grandfather's farm in western Pennsylvania. Sur?rounded by miles of winding stone walls,the house and field provided endless hours of fun for a city kid like me.

I can still remember one afternoon when I was eight years old. Since my first visit to the farm,I had wanted more than anything to be allowed to climb the stone walls surrounding the houses. My parents would never approve. The walls were old;some stones were missing,others loose and falling. Still,my idea to climb across those walls grew so strong that finally,one spring afternoon,I had all my courage to enter the living room,where the adults had gathered after Sunday din?ner.

"I,uh―I want to climb the stone walls," I said. Everyone looked up. "Can I climb the stone walls?" Immediately voices of disagreement went up from the women in the room. "Heavens,no!You'll hurt yourself!" I wasn't too disappoint?ed; the response was just as I'd expected. But before I could leave the room,I was stopped by my grandfather's loud voice. "Now hold on just a minute,"I heard him say. "Let the boy climb the stone walls. He has to learn to do things for himself."

"Go”, he said to me, "and come and see me when you get back."For the next two and a half hours I climbed those old walls―and had the time of my life. Later I met with my grandfather to tell him about my adventures. I'll never forget what he said. "Fred," he said,smiling. "You made this day a special day just by being yourself. Always remember that there's only one person in this whole world like you,and that I like you exactly as you are."

Many years have passed since then,and today I host the television programme Mister Rogers' Neighbourhood,seen by millions of children throughout America. There have been changes over the years,but one thing remains the same:my mes?sage to children at the end of almost every visit. "There's only one person in this whole world like you”,the kids can count on hearing me say, "and people can like you exactly as you are."

Earthquakes,also called temblors (地震) ,can be so extremely destructive; it's hard to imagine they occur by the thousands every day around the world,usually in the form of small tremors.

Some 80 per cent of all the planet's earthquakes occur along the rim of the Pacific Ocean,called the "Ring of Fire" because of the preponderance (数量上的优势) of volcanic activity there as well. Most earthquakes occur at fault zones,where tectonic plates―giant rock slabs that make up the earth's upper lay?er―crash or slide against each other. These impacts are usually gradual and unnoticeable on the surface. However,immense stress can build up between plates. When this stress is released quickly,it sends massive vibrations (震动) ,called seis?mic waves,often hundreds of miles through the rock and up to the surface. Other quakes can occur far from fault zones when plates are stretched or squeezed.

Scientists assign a magnitude rating to earthquakes based on the strength and du?ration of their seismic waves. A quake measuring 3  to 5 is considered minor or light; 5 to 7  is moderate to strong; 7 to 8  is major,and 8 or more is great.

On average,a magnitude 8  quake strikes somewhere every year and some 10,000 people die worldwide annually in earthquakes. Collapsing buildings claim by far the majority of lives,but the destruction is often compounded (加重) by mud slides,fires,floods,or tsunamis. Smaller temblors that usually occur in the days following a large earthquake can complicate rescue efforts and cause further death and destruction.

Loss of life can be avoided through emergency planning,education,and the construction of buildings that sway rather than break under the stress of an earth?quake.

1. Why is the rim of the Pacific Ocean called the "Ring of Fire"?

   A. Because 80 %of the earth's quakes occur there.

   B. Because there are many fault zones along the rim.

   C. Because volcanoes happen actively along the rim.

   D. Because seismic waves are sent out from the rim.

2. An earthquake can't happen when         .

   A. tectonic plates collide against each other

   B. tectonic plates are stretched

   C. tectonic plates move slightly

   D. tectonic plates are squeezed

3. A major earthquake is measured at a magnitude of         .

   A. 7 to 8     B. 5 to 7

   C. 3 to 5     D. 8 or more

4. What is the most effective way to avoid death in earthquakes?

   A. To make quick rescue efforts.

   B. To educate people knowledge of earthquakes.

   C. To have a detailed plan in an emergency.

   D. To build buildings strong enough.
