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.  
【小题1】What makes Grimsvom different from other volcanoes? 

A．It is below ice.
B．It lies under the sea
C．It is the largest volcano
D．It is lava affects the airlines
【小题2】What keeps Grimsvotn still? 
A．The slow flow of water
B．The low water temperature
C．The thick glacier
D．The water pressure
【小题3】Which of the following is the result of the volcanic eruption? 
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
【小题4】This text is most probably taken from_ 
A．a research paper
B．a newspaper report
C．a class presentation
D．a geography textbook.

【小题2】D
【小题3】C
【小题4】B

解析【小题1】细节理解题。由第二段的第一行What makes Grimsvom different is that it lies under a huge glacier（冰川） of ice up to 12 maters thick.可知它有别于其他火山是位于巨大冰川之下，选A.
【小题2】细节理解题。由第二段的第四行This layer of water puts pressure on the volcano, keeping it stable,可知水的压力让它稳定，选D。
【小题3】细节理解题。由最后两段可以看出A,B,D都不存在，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..选C符合。

第二节简答题（共3小题；每小题1.5分，满分4.5分）
Tsunamis (海啸) are a series of huge waves created by an underground movement such as an earthquake or a volcanic eruption (火山喷发) . A tsunami can travel hundreds of miles per hour in the open ocean and hit the land with huge waves.
From the area where the tsunamis come, waves travel in all directions. Once the waves approach the coast, they will become more than 100 feet in height. The topography (地形) of the coastline and the ocean floor will influence the size of the wave. There may be more than one wave and the latter one may be larger than the one before. That is why a small tsunami at one beach can be a huge wave a few miles away.
All tsunamis are dangerous, even if they may not damage every coastline they strike. A tsunami can strike anywhere along most of the US coastline. Many harmful tsunamis have occurred along the coasts of California, Oregon, Washington, Alaska and Hawaii.
A movement of the ocean floor, caused by earthquakes, most often causes tsunamis. If a tsunami occurs close to a coast, the first wave could reach the beach in a few minutes, even before a warning is given. Areas are at greater risk if they are less than 25 feet above sea level and within a mile of the coastline. Drowning is the most common cause of death during a tsunami. Tsunami waves are very harmful to buildings. Other dangers include floods, pollution of drinking water, and fires from gas lines.
An accurate prediction (预报) system will allow authorities (官方) to issue timely warnings and save lives in the event of a shore-bound tsunami. But forecasting tsunamis accurately is very difficult because the ocean is usually calm before they strike land.

Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway.

WHO spokesman Daniel Epstein said the microscopic(微小的) ash is potentially dangerous for people when it starts to reach the Earth because inhaled(吸入) particles can enter the lungs and cause respiratory problems. And he also said Europeans who go outside might want to consider wearing a mask.

Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were "hysterical." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder. During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation even in healthy people. But once it falls from a greater distance — like from the cloud currently hovering above Europe — its health effects are often minimal, experts say.

"Not all particles are created equal," said Ken Donaldson, a professor of respiratory toxicology at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be negligible and that only those in the near districts of the Icelandic volcano would likely be at risk.

Dr. Stephen Spiro, a professor of respiratory medicine and deputy chair of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical."

D. The volcanic ash was more dangerous than cigarette smoke or pollution.

3. The underlined word “hysterical” in Paragraph4 most probably means        .

A. amazing          B. practical        C. valuable            D. overstated

4. What can we learn from the passage?

    A. The volcanic ash wouldn’t be harmful to people.

B. All experts thought the volcanic ash did great harm to our health.

C. People close to the volcano would likely be at risk according to some experts.   

D. Europeans should stay indoors because Iceland's volcano starts settling.
