After arriving， we all rushed down to the river and had a swim. Standing by the river， we noticed that it was surrounded环绕 by cliffs悬崖. If someone wanted to reach the river at this point， he had to walk past our camp.Several days later， the scoutmaster had to be away for a day. That afternoon， we had supper early. We were sitting round the fire， eating and talking， when a man walked past and went down towards the river. We all felt that this man looked very strange， but， because each of us was afraid of looking very stupid， no one said anything.We ate rather slowly， taking as long as possible. After finishing， we collected our plates together so that we could take them to the river where we always washed them. But no one moved towards the riverwe stood looking at each other ashamed. Then all shouting at once， we began talking about the man who had walked past us. We agreed how strange he looked and we wondered what he could be doing by the river.

Moving very slowly and keeping in the shadow， we crept down towards the bank. One boy climbed a tree so that he could see everything clearly.

They see the sights that Pompeii is famous forits stadium and theatres， its shops and restaurants. The tourists do not， however， see Pompeiis people. They do not see them because Pompeii has no people. No one has lived in Pompeii for almost 2000 years.Once， Pompeii was a busy city of 22000 people. It lay at the foot of Mount Vesuvius， a grass-covered volcano火山. Mount Vesuvius had not erupted喷发for centuries， so the people of Pompeii felt safe. But they were not.In August of AD 79， Mount Vesuvius erupted. The entire top of the mountain exploded， and a huge black cloud rose into the air. Soon stones and hot ash 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 stone and ash. Then， in the year 1861， an Italian scientist named Giuseppe began to uncover Pompeii. Slowly， carefully， Giuseppe and his men dug. The city looked almost the same as it had looked in AD 79. There were streets and fountains， houses and shops. There was a stadium with 20000 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 colour 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 breada 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.Giuseppe 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.1. Why do large numbers of people come to Pompeii each year？A. To visit the volcano.
