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 

This text is most probably taken from_______________.

A. a research paper            B. a newspaper report 

C. a class presentation          D. a geography textbook.

A teddy bear from Cumbria is launching into space to raise cash for charity(慈善).

Terence, an experienced traveller who has been to Iraq, will be the guest of honour on aviation(航行) legend Burt Rutan’s Spaceship One when it flies above Earth. The mission takes off from California on September 29, and on his return the cuddly toy will be auctioned off(拍卖) in aid of the North Air Ambulance Appeal(北部空中救护服务中心).

Spaceship One is the world’s first private spacecraft, and is competing for a prestigious space travel prize. Chief executive of the Great North Air Ambulance Service (GNAAS), Graham Pickering, said “flying officer” Terence had been handed over to the RAF six months ago and staff had been receiving postcards from him ever since.

He said, “Terence was a fundraising idea that really took off. We have received pictures of him in a U2 craft, trying parachuting and even looking drunk and disorderly. When the RAF finally discharge him he will be a very rare bear indeed—we just hope he does not burn up on re-entry to Earth.”

GNAAS, which needs charitable donations of more than £2m a year, has three air ambulances(空中救护机).

Peter Bond, spokesman for the Royal Astronomical Society, said Terence’s safety was not guaranteed. He said, “This is a new and experimental craft and this will only be the second time it has flown. During its first voyage it developed technical problems but hopefully they have now been resolved.”

Since May, Terence has spent time with members of 100 Squadron(空军中队) based at RAF Leeming in Basra, Iraq, and at air shows with performing fighter planes.

Spaceship One will fly 100km (62 miles) above the Earth’s surface, just breaking through the planet’s atmosphere.

If it repeats the feat(技艺) inside two weeks, it will claim the $10m Ansari X-Prize set up to encourage the private space flight business.

Terence is ________.

A. a real bear living in England           B. an experienced astronaut

C. an air force officer                         D. a toy bear

We can infer that________.

A. after this space flight, Spaceship One will get the $10m Ansari X-Prize

B. it is dangerous for a spaceship to re-enter the earth atmosphere

C. Terence will be very safe on the flight

D. Spaceship One is just an ordinary plane

Which of the following is true of Spaceship One?

A. Spaceship One is the world’s first spacecraft.

B. The purpose of its flight is to collect money for the charity.

C. The purpose of its flight is to compete for a prestigious space travel prize.

D. Spaceship One has never flown.

Which of the following is the best title?

A. Teddy bear astronaut to lift off        B. Spaceship One to lift off

C. Space flight                                 D. The toy bear will be auctioned off

On numerous drives throughout my childhood, my mother would suddenly pull over the car to examine a flower by the side of the road or rescue a beetle (甲虫) from certain tragedy while I, in my late teens and early twenties, sat impatiently in the car.

    Though Mother’s Day follows Earth Day, for me, they have always been related. My mom has been “green” since she became concerned about the environment. Part of this habit was born of thrift (节俭). Like her mother and her grandmother before her, Mom saves glass jars, empty cheese containers and re-uses her plastic bags.

    Mom creates a kind of give-and-take relationship with wildlife in her yard. She knows to pick the apples on her trees a little early to fend off the bears and that if she leaves the bird feeders out at night, it’s likely they’ll be knocked down by a family of raccoons (浣熊). Spiders that make their way into the house are captured (捕获) in a juice glass and set loose in the garden.

    I try to teach my children that looking out for the environment starts with being aware of the environment. On busy streets, we look for spent (开败的) dandelions (蒲公英) to parachute; we say hello to neighborhood cats and pick up plastic cups and paper bags. This teaching comes easily, I realize, because I was taught so well by example. Mom didn’t need to lecture; she didn’t need to beat a drum to change the world. She simply slowed down enough to enjoy living in it and with that joy came compassion and an instinct (本能) for preservation.

    I am slowing down and it isn’t because of the weight of my nearly forty years on the planet, it is out of my concern for the planet itself. I’ve begun to save glass jars and re-use packing envelopes. I pause in my daily tasks to watch the squirrels race each other through the palm (棕榈树) leaves above my porch (门廊).

    Last summer, in the company of my son and daughter, I planted tomatoes in my yard. With the heat of August around me, I ate the first while sitting on my low wall with dirt on my hands. Warm from the sun, it burst on my tongue with a sweetness I immediately wanted to share with my mom.

Why does the author say Earth Day is connected with Mother’s Day?

A. Because Mother’s Day falls shortly after Earth Day.

B. To stress that all the older women in her family are environmentalists.

C. To stress how much her mother cares about the environment.

D. Because on Mother’s Day her mother shows her how to be friend to nature.

According to the fourth paragraph, which of the following is the author’s mother NOT likely to do?

A. When she came across a lost dog, she helped it to find its shelter.

B. In spring, she spent some time watching the plants growing in the garden.

    C. She joined in the campaign to encourage the public to contribute actively towards a better environment.

    D. She walked to a nearby shop which was within ten minutes’ walk rather than drove there.

What can we conclude from the article?

A. The author’s mother is very patient with her children.

B. The author’s mother knows how to live in harmony with nature.

C. The author’s mother always took care of the wildlife that came into her yard.

D. The author’s mother used to remind her to slow down to protect the environment.

We can infer from the article that ______.

A. the author thinks that too many people now label themselves environmentalists   

B. the author’s mother knows how to get rid of the wildlife in her yard   

C. the author believes that only by learning to slow down, can we enjoy life

D. the author realizes that she should teach her children by example as well

What is the main idea of the last three paragraphs?

A. How the author taught her children to protect the environment.

B. How the author’s mother influenced the author.

C. What inspired the author to slow down and enjoy life.

D. How the author spent her time with her children.
