Landslides happen when large amounts of rock, mud and other loose materials are suddenly uprooted and sent sliding down a slope. This might be caused by an earthquake or it might happen after a heavy rain or when soil becomes waterlogged after a fall of snow. As the material loses its grip and begins to move down the slope it gathers speed and sweeps up more material with devastating results. Nepal suffers from frequent landslides because the hillsides have been stripped of trees. When it rains the water soaks into the soil and this slides down the mountainside. The worst landslide in Wales’ history came about with the collapse of an artificial mountain on 21 October 1966. A 250-metre high mountain of waste material from the local coal mine had been piled up outside the village of Aberfan. Two million tons of rock, coal and mud began to move with a thunderous roar towards’the local school, uprooting trees and crushing houses. It was the start of the school day and almost every child in the village was there. The building collapsed under the weight of the avalanche, and crushed children and their teachers beneath it. One hundred and forty five people, among them 116 children, lost their lives. The Wales’ artificial mountain collapsed because

Diogenes was the founder of the creed called Cynicism (the word means "doggishness"); he spent much of his life in the rich, lazy, corrupt Greek city of Corinth, mocking and satirizing its people, and occasionally converting one of them. He was not crazy. He was a philosopher who wrote plays and poems and essays expounding his doctrine; he talked to those who cared to listen; he had pupils who admired him. But he taught chiefly by example. All should live naturally, he said, for what is natural is normal and cannot possibly be evil or shameful. Live without conventions, which are artificial and false; escape complexities and superfluities and extravagance; only so can you live a free life. The rich man believes he possesses his big house with its many rooms and its elaborate furniture, his pictures and his expensive clothes, his horses and his servants and his bank accounts. He does not. He depends on them, he worries about them, he spends most of his life’s energy looking after them; the thought of losing them makes him sick with anxiety. They possess him. He is their slave. In order to procure a quantity of false, perishable goods he has sold the only true, lasting good, his own independence. Diogenes thought most people were only half-alive, most men only half-men. At bright noonday he walked through the market place carrying a lighted lamp and inspecting the face of everyone he met. They asked him why. Diogenes answered, "I am trying to find a man." To a gentleman whose servant was putting on his shoes for him, Diogenes said, "You won’t be really happy until he wipes your nose for you; that will come after you lose the use of your hands." And so he lived—like a dog, some said, because he cared nothing for privacy and other human conventions, and because he showed his teeth and barked at those whom he disliked. Now he was lying in the sunlight, as contented as a dog on the warm ground, happier than the Shah of Persia. Although he knew he was going to have an important visitor, he would not move. According to the passage, Diogenes ______.

What is Ginger It is ______ with an aromatic flavor. Ginger was traded in Europe for sake of ______.
It was the single, strangely spiraled tusk that first alerted scientists. Sticking out of the ice covered by Siberian soil, like an ivory tombstone, it revealed the. presence of a true scientific wonder: underneath lay the frozen body of a mammoth. The discovery has presented researchers with an unprecedented challenge--to move to laboratory, a mammoth’s entire, undisturbed body where it can be analyzed at leisure and its biological secrets revealed. Last week, scientists completed the first stage of this remarkable transfer, using a helicopter to lift a twenty-three-ton block of ice and mammoth to a new site where defrosting can be started. As one of the team, Dutch paleontologist Dick Mol put it, "It’s very exciting. I’ve been working on mammoths for more than 25 years, and this is a dream for me—to find the soft parts and touch them and even smell them." In particular, the discovery and recovery of the 23,000-year-old body has raised speculation that it may be possible to clone a mammoth from one of its cells. Could the same process used to clone Dolly the sheep be attempted with a mammoth, using an elephant as a surrogate mother It is certainly an enticing prospect. Herds of woolly mammoths grazing the pastures of the world’s many natural parks would be a mighty attraction, and a massive triumph for modem science, showing it could even resurrect eradicated species. Extinction would no longer be forever. Mammoths once roamed the world’s northern hemisphere until they abruptly disappeared. Some. scientists argue that as the last Ice Age ended, the world went through major ecological changes, and these large woolly mammals found life awkward, sweaty and unaccommodating. No longer able to compete for resources, they became extinct. The word "defrosting" in the third paragraph most probably means
