A volcanic eruption in Iceland has sent ash across northern Europe. Airlines have stopped

A 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.
Grimsvotn is one of the largest and most active volcanoes in Europe. What makes
Grimsvotn different is that it lies under a huge glacier（冰川）of ice up to 12 metres thick. The hot volcano heats up the ice above it, which then forms a layer(层)
of water between glacier and 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 is happening 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 eating ash-covered grass or the sharp objects.
【小题1】What makes Grimsvotn different from other volcanoes?A．It is under the sea.B．Its lava affects the airlines.C．It is the largest volcano.D．It is below ice.【小题2】What keeps Grimsvotn still?A．The slow flow of water..B．The thick glacier.C．The water pressure.D．The low water temperature.【小题3】Which of the following is the result of the volcano eruption?A．It becomes dangerous for animals to eat outside. B．Famers have lost many of their animals.C．Airlines suffer from the loss of planes.D．People stop traveling in Europe.【小题4】how many passengers were forced to stay in the airport?A．thousands of passengersB．hundreds of passengersC．ten thousands of passengersD．20000 of passengersD

(答案→)D 解析：本文详细介绍了冰岛的火山爆发对欧洲航空业的影响，并解释了冰岛火山的特点。【小题1】D 细节题。根据第二段第2行What makes Grimsvotn different is that it lies under a huge glacier（冰川）of ice up to 12 metres thick.说明这座火山的特别之处在于它是在于冰川之下。故D正确。【小题2】C 细节题。感觉第二段3，4行The hot volcano heats up the ice above it, which then forms a layer(层)of water between glacier and the volcano, keeping it stable.说明是冰川和火山之间的水压让冰山很稳定，故C正确。【小题3】A 细节题。根据文章最后一段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 eating ash-covered grass or the sharp objects.说明四处落下的火山灰让动物不能吃外面的草等食物了。故A正确。【小题4】B 细节题。根据第一段最后一句leaving hundreds of passengers stuck in airports.说明B正确。
