The volcano is one of the most surprising frightening things of nature. Maybe you have seen pic??tures of these " fireworks " of nature. Sometimes when a volcano erupts, a very large wall of melted rock moves down the side of a mountain. It looks like a " river of fire". Sometimes volcanoes ex??plode, throwing the melted rock and ashes high into the air. But where does this melted rock come from?
The earth is made up of many layers (层). The top layer that we see is called the crust. Under the crust are many layers of hard rock. But far, far beneath the crust the rock is so hot that it is soft. In some places it even melts. The melted rock is called magma. Sometimes the magma breaks out to the surface through cracks (裂缝) in the crust. These cracks are volcanoes.
Most people think of mountains when they think of volcanoes. But not every mountain is a volca??no. A volcano is simply the opening in the earth from which the magma escapes. The hot magma, or lava as it is called, cools and builds up on the surface of the earth. Over thousands of years, this pile of cooled lava can grow to be very, very big. For example, the highest mountain in Africa, Kilimanja??ro, is a volcano. It rises more than 16,000 feet above the ground around it.

Paracutin was born in Mexico in February, 1943. At the end of one week Paracutin was 500 feet high, and it is now over 9, 000 feet high. Today Paracutin is asleep.
What is Paracutin? It was the first volcano(火山) in the world which was seen from its birth right up to the present day. On February 20, 1943, a peasant and his wife set out to work in their corn fields from the Mexican village of Paracutin. They were surprised to find the earth warm under their feet. Suddenly they heard noises deep in the earth and a small hole appeared in their field. In the afternoon there was a sudden loud noise and stones were thrown high in the air. The peasants ran from the field and turned to watch. They saw the birth of a volcano.
Large quantities of stone and lava(岩浆) broke out and a little hill began to form. By evening this hill was 100 feet high and hot ashes(灰烬) were falling on the village. At night the strong light of the hot lava lit up the countryside. The trees near the village were killed and the villagers had to leave their houses. When the village was destroyed, its name was given to the volcano. The news quickly reached Mexico City, far to the east. Many people came to watch the scene. The volcano grew and grew for ten years and hundreds of square miles of forest were destroyed. Then Paracutin went to sleep.

One Saturday afternoon in February, 1943, a farmer in Mexico stopped working for a moment and looked across his fields of corn. Suddenly he saw a thin line of white smoke curling up out of his field, about 200 feet from where he stood. As he went toward the smoke to see what it was, he heard a strange noise. The line of smoke became bigger. It looked as if some great force were pushing it up into the sky.
The farmer rushed home to get his wife. While he was urging his wife to hurry from the house, the earth shook violently. When he stood up after the earth stopped shaking, he looked across the field and saw that great flames were rising from his cornfield. A volcano was being born!
They hurried across the shaking earth to the village of Particutin, which was toward their farm. They found the village was seriously destroyed and the road from the village was filled with frightened people hurrying to safety.
Particutin did not become dark that night. The volcano lighted up the sky for miles around. Flames rushed out of the ground. The volcano threw hot stones a thousand feet through the air. Great explosion shook the earth and heavy black ashes fell from the sky, covering the roofs in Mexico city, 180 miles away.
But that was not all. On 
the third evening a float of lava（火山岩）began to boil up from the centre of the volcano. It came over the edge in a heavy flow, 2,000 feet wide, and travelled slowly across the valley, bringing certain death to everything that could not move from its path.

Every year thousands of tourists visit Pompeii, Italy. They see the sight that Pompeii is famous for—its stadium and theaters, its shops and restaurants. The tourists do not, however, see Pompeii’s people. No one has lived in Pompeii for almost 2,ooo years.
Once Pompeii was a busy city of 22,000 people. It lay at the foot of Mt Vesuvius, a grass-covered volcano. Mt Vesuvius had not erupted for centuries, so the people of Pompeii felt safe. But they were not. In August of the year 79 AD, Mt Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ashes began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.
For centuries, Pompeii lay buried under stones and ashes. Then in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city almost looked the same as it had looked in 79 AD. There were streets and fountains, houses and shops. There was a stadium with 20,000 seats. Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue color in the bottom, so we know that the people of Pompeii liked wine. They liked bread too; metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread—a type of bread that is still sold in Italy today. Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eye-makeup.
Ginseppe has died, but his work continues. One-fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii.
【小题1】Why do large number of people come to Pompeii each year?
| A．To visit the volcano. | B．To shop and eat there. |
| C．To watch sports and plays. | D．To see how Pompeiians lived. |
| A．Because Ginseppe and his men dug it slowly and carefully. |
| B．Because the city was buried alive and remained untouched. |
| C．Because scientists successfully rebuilt the city with everyday objects. |
| D．Because nobody had lived in the city ever since the volcano erupted. |
A. They lived more or less the same as Italians now do.
B. They liked women wearing all kinds of makeup.
C. They enjoyed a lazy life with drinking and eating.
D. They went back to Pompeii after the eruption in 79 AD.
On April 10, 1815, Mount Tambora in Indonesia erupted with great force. Fifty cubic kilometers of magma (岩浆) flew from its peak (山顶) and a blanket of ash as thick as one centimeter fell over more than 500,000 square kilometers of Indonesia and the Java Sea. The eruption destroyed Tambora’s peak and formed a hole six by seven kilometers wide. The eruption and resulting tsunamis killed 10,000 people. The agricultural loss and disease brought about by the thick ash caused the deaths of 82,000 more.
Indonesia was rocked again in 1883. On August 26, a small volcano on an uninhabited island between Sumatra and Java, erupted. The eruption produced an ash cloud 80 kilometers high and was heard in Australia—4,800 kilometers away. The eruption also caused a tsunami, which pounded (击打) the shores of Java and Sumatra—killing 36,000 people.
In 1902, St. Pierre was a thriving (兴盛的) community and the largest town on the French colony of Martinique in the Caribbean Sea. Mont Pelee cast a shadow over the town from where it stood, eight kilometers to the north. The townspeople were used to the light continuous sounds of the mountain, but in May, 1902 Pelee started to get really unstable. Clouds of steam and ash poured from the volcano and on May 8, Pelee erupted. Superheated gas and steaming volcanic ash flew out, pouring down the mountain at high speed. Within seconds, the deadly gas cloud had destroyed the town of St. Pierre and incinerated everyone in it — except one prisoner in a basement cell. It was the worst volcano disaster of the 20th century.
