Question

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.

Grimsvom 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.

【解析】文章介绍了冰岛的火山爆发导致欧洲飞机改变航道，并介绍这一火山的相关情况。

1.细节题。由第二段的第一行What makes Grimsvotn different is that it lies under a huge glacierof ice up to 12 maters thick.可知它有别于其是位于巨大冰川之下，， A.

2.D .细节理解题。由第二段的This layer of water puts pressure on the volcano, keeping it stable,可知水的压力让它稳定D。。。。

3.C细节理解题。由最后两段可以看出由最后两段可以看出由最后两段可以看出由最后两段可以看出A,B,D都，The eruption has also caused problems for animals in Iceland .Farmers are keeping their animals inside to stop them from eating ash- covered grass to the sharp object. C正确。

4.B。推理判断题。通读全文可知是一篇新闻报道通读全文可知是一篇新闻报道，选B。
