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.

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.  

What keeps Grimsvom still? 

A. The slow flow of water       B. The low water temperature 

C. The thick glacier            D. The water pressure 

Which of the following is true? 

A. People stop traveling in Europe   

B. Airlines suffer from the loss of planes 

C. It becomes dangerous for animals to eat outside 

D. Farmers have lost many of their animals

In earliest times, men considered lightning （闪电）to be one of the great mysteries（神密） of nature． Some ancient people believed that lightning and thunder were the weapons(武器) of the gods．

    In reality lightning is a flow of electricity （电流）formed high above the earth． A single flash（闪烁） of lightning 1.6 kilometers long has enough electricity to light one million light bulbs．

    The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752． In the same year he also built the first Lightning Rod (避雷针)． His device（发明物） protects buildings from being damaged by lightning．

     Modern science has discovered that one stroke of lightning contains more than 15 million volts(伏特)． A spark（火花） between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second．Scientists estimate (估计) that there are about 2,000 million flashes of lightning per year． Lightning hits the Empire, State Building in New York City 30 to 48 times a year． In the United States alone it kills an average of one person every day．

    The safest place to be in case of an electrical storm is in a closed car． Outside, one should go to low ground and not get under trees． Also, one should stay out of water and away from metal fences． Inside a house, people should avoid open doorways and windows and not touch wires or metal things．

    With lightning, it's better to be safe than sorry.?
