　　历年雅思阅读真题1：

　　The eruption in May 1980 of Mount St. Helens, Washington State, astounded the world with

　　its violence. A gigantic explosion tore much of the volcano's summit to fragments; the energy

　　released was equal to that of 500 of the nuclear bombs that destroyed Hiroshima in 1945.

　　历年雅思阅读真题2：The event occurred along the boundary of two of the moving plates that make up the Earth's

　　crust. They meet at the junction of the North American continent and the Pacific Ocean. One

　　edge of the continental North American plate over-rides the oceanic Juan de Fuca micro-plate,

　　producing the volcanic Cascade range that includes Mounts Baker, Rainier and Hood, and Lassen

　　Peak as well as Mount St. Helens.

　　历年雅思阅读真题3：Until Mount St. Helens began to stir, only Mount Baker and Lassen Peak had shown signs of

　　life during the 20th century. According to geological evidence found by the United States

　　Geological Survey, there had been two major eruptions of Mount St. Helens in the recent

　　(geologically speaking)past: around 1900 B.C., and about A.D. 1500. Since the arrival of

　　Europeans in the region, it had experienced a single period of spasmodic activity, between 1831

　　and 1857. Then, for more than a century, Mount St. Helens lay dormant.

　　历年雅思阅读真题4：By 1979, the Geological Survey, alerted by signs of renewed activity, had been monitoring

　　the volcano for 18 months. It warned the local population against being deceived by the

　　mountain's outward calm, and forecast that an eruption would take place before the end of the

　　century. The inhabitants of the area did not have to wait that long. On March 27, 1980,a few

　　clouds of smoke formed above the summit , and slight tremors were felt. On the 28th, larger and

　　darker clouds,. consisting of gas and ashes,. emerged and climbed as high as 20,000 feet. In April

　　a slight lull ensued, but the volcanologists remained pessimistic. The, in early May, the northern

　　flank of the mountain bulged, and the summit rose by 500 feet.

　　历年雅思阅读真题5：Steps were taken to evacuate the population. Most- campers, hikers, timbercuttersleft the

　　slopes of the mountain. Eighty-four-year-old Harry Truman, a holiday lodge owner who had lived

　　there for more than 50 years, refused to be evacuated, in spite of official and public, including an

　　entire class of school children, wrote to him, begging him to leave. He never did.

　　历年雅思阅读真题6：On May 18, at 8.32 in the morning, Mount St. Helens blew its top. literally. Suddenly, it was

　　1300 feet shorter than it had been before its growth had begun. Over half a cubic mile of rock had

　　disintegrated . At the same moment, an earthquake with an intensity of 5 on the Richter scale was

　　recorded. It triggered an avalanche of snow and ice. mixed with hot rock-the entire north face of

　　the mountain had fallen away. A wave of scorching volcanic gas and rock fragments shot

　　horizontally from the volcano's riven flank, at an inescapable 200 miles per hour. As the sliding

　　ice and snow melted, it touched off devastating torrents of mud and debris, which destroyed all

　　life in their path. Pulverised, which destroyed all life in their path. Pulverised rock climbed as a

　　dust cloud into the atmosphere. Finally, viscous lava, accompanied by burning clouds of ash and

　　gas, welled out of volcano's new crater, and from lesser vents and cracks in its flanks.

　　历年雅思阅读真题7：Afterwards, scientists were able to analyse the sequence of events. First, magmamolten

　　rock-at temperatures above 2000oF. had surged into the volcano from the Earth's mantle. The

　　build-up was accompanied by an accumulation of gas, which increased as the mass of magma

　　grew. It was the pressure inside the mountain that made it swell. Next, the rise in gas pressure

　　caused a violent decompression. Which ejected the shattered summit like a cork from a shaken

　　soda bottle. With the summit gone, the molten rock within was released in a jet of gas and

　　fragmented magma, and lava welled from the crater.

　　历年雅思阅读真题8：The effects of the Mount St. Helens eruption were catastrophic. Almost all the trees of the

　　surrounding forest, mainly Douglas firs. were flattened. and their branches and bark ripped off by

　　the shock wave of the explosion. Ash and mud spread over nearly 200 square miles of country. All

　　the towns and settlements in the area were smothered in an even coating of ash. Volcanic ash silted

　　up the Columbia River 35 miles away, reducing the debris that accumulated at the foot of the

　　volcano reached a depth. in places, of 200 feet.

　　历年雅思阅读真题9：The eruption of Mount St. Helens was one of the most closely observed and analysed in

　　history. Because geologists had been expecting the event, they were able to amass vast amounts of

　　technical data when it happened. Study of atmospheric particles formed as a result of the

　　explosion showed that droplets of sulphuric acid, acting as a screen between the Sun and the

　　Earth's surface, caused a distinct drop in temperature. There is no doubt that the activity of Mount

　　St. Helens and other volcanoes since 1980 has influenced our climate . Even so, it has been

　　calculated that the quantity of dust ejected by Mount St. Helens - a quarter of a cubic mile- was

　　negligible in comparison with that thrown out by earlier eruptions, such as that of Mount Katmai

　　in Alaska in 1912 (three cubic miles). The volcano is still active. Lava domes have formed inside

　　the new crater, and have periodically burst. The threat of Mount St Helens lives on.
