CA volcanic eruption in Iceland has sent ash across northern Europe. Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports.Grirmsvom is one of the largest and most active volcanoes in Europe. What makes Grimsvom different is that it lies under a huge glacier（冰川） of ice up to 12 maters thick. The hot volcano heats up the ice above it, which then forms a layer（层）of water between the glacier and the volcano This layer of water puts pressure on the volcano, keeping it stable, As the water flows out from under the glacier, the pressure lifts. The lava（岩浆） from the volcano then comes up to the surface. This is exactly what happened today.Now, airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. According to KLM. one of Europe’s biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane’s engines, causing damage to the plane.The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp. Glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them from eating ash- covered grass to the sharp object.64. What makes Grimsvom different from other volcanoes?A. It is below ice.B. It lies under the seaC. It is the largest volcanoD. It is lava affects the airlines

Passage ThreeIn an age when waste today means a lack tomorrow, making use of every available resource becomes more and more important. As coal is being used in greater and greater amounts to produce electricity, larger amounts of ash, by-product of coal, are produced. When coal is burnedin a boiler, two kinds of ash by-product are produced, a heavy bottom ash and a fine-as-powder fly ash that is filtered and captured by precipitators. About 10 to 15 percent of the coal by-product is bottom ash which is used like sand on icy city streets and highways and also on highways as paving material. It is the fly ash, however, that is receiving the greater amount of attention. Fly ash may be used as an additive to concrete in the construction of dams, bricks, and roads, and can replace up to 20 percent of the cement used in concrete. As a by-product of burned coal, fly ash requires no additional expenditure of energy to be produced, while cement production requires great amounts of energy.In addition to using fly ash as a concrete additive, the technology is available to extract the main mineral components-aluminum, silicon, and magnetic. Today, extracting these components is a very expensive process, but the time may come when it is cheaper to extract these products from ash than to mine new supplies.41. What can be used as a material to pave roads?A. The coal by-product.B. Additive.C. Fine-as-powder fly ash.D. Both B and C.
According to the passage, what attracts man's greater attention?A. Fly ash.B. The construction of dams, bricks, and roads.C. Extracting aluminum, silicon, and magnetic from ash.D. The available technology.

共用题干Older Volcanic EruptionsVolcanoes were more destructive in ancient history,not because they were bigger,but because the carbon dioxide they released wiped out life with greater ease.Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions.Not all volcanic eruptions killed off large numbers of animals,but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock.To his surprise,the older the massive.volcanic eruptions were,the more damage they seemed to do.He calculated the"killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava（熔岩）that they produced.He found that size for size,older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.The Permian（二叠纪）extinction,for example,which happened 250 million years ago,is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe.Those volcanoes are thought to have pumped out about 1 0 gigatonnes（十亿吨）of carbon as carbon dioxide.The global warming that followed wiped out 80 percent of all marine genera（种类）at the time,and it took 5 million years for the planet to recover.Yet 60 million years ago,there was another huge amount of volcanic activity and global warming but no mass extinction.Some animals did disappear but things returned to normal within ten thousands of years."The most recent ones hardly have an effect at all,"Wignall says.He ignored the extinction which wiped out the dinosaurs 65 million years ago,because many scientists believe it was primarily caused by the impact of an asteroid（小行星）.He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2.Vincent Courtillot,director of the Paris Geophysical InstitUte in France,says that Wignall's idea is provoca- tive.But he says it is incredibly hard to do these sorts of calculations.He points out that the killing power of volcanic eruptions depends on how long they lasted.And it is impossible to tell whether the huge blasts lasted for thousands or millions of years.He also adds that it is difficult to estimate how much lava prehistoric volcanoes produced,and that lava volume may not necessarily correspond to carbon dioxide emissions.Why were older volcanic eruptions more destructive than more recent ones according to Wignall?A:Because they were brighter.B:Because they were larger.C:Because more recent life forms were better adapted to CO2.D:Because older volcanic eruptions released more lava.
