Passage Fourteen(Antarctica and Environment)
Antarctica has actually become a kind of space station – a unique observation post for detecting important changes in the world’s environment. Remote from major sources of pollution and the complex geological and ecological systems that prevail elsewhere, Antarctica makes possible scientific measurements that are often sharper and easier to interpret than those made in other parts of the world.
Growing numbers of scientists therefore see Antarctica as a distant-early-warning sensor, where potentially dangerous global trends may be spotted before they show up to the north. One promising field of investigation is glaciology. Scholars from the United States, Switzerland, and France are pursuing seven separate but related projects that reflect their concern for the health of the West Antarctic Ice Sheet – a concern they believe the world at large should share.
The Transantarctic Mountain, some of them more than 14,000 feet high, divide the continent into two very different regions. The part of the continent to the “east” of the mountains is a high plateau covered by an ice sheet nearly two miles thick. “West” of the mountain, the half of the continent south of the Americas is also covered by an ice sheet, but there the ice rests on rock that is mostly well below sea level. If the West Antarctic Ice Sheet disappeared, the western part of the continent would be reduced to a sparse cluster of island.
While ice and snow are obviously central to many environmental experiments, others focus on the mysterious “dry valley” of Antarctica, valleys that contain little ice or snow even in the depths of winter. Slashed through the mountains of southern Victoria Land, these valleys once held enormous glaciers that descended 9,000 feet from the polar plateau to the Ross Sea. Now the glaciers are gone, perhaps a casualty of the global warming trend during the 10,000 years since the ice age. Even the snow that falls in the dry valleys is blasted out by vicious winds that roars down from the polar plateau to the sea. Left bare are spectacular gorges, rippled fields of sand dunes, clusters of boulders sculptured into fantastic shapes by 100-mile-an-hour winds, and an aura of extraterrestrial desolation.
Despite the unearthly aspect of the dry valleys, some scientists believe they may carry a message of hope of the verdant parts of the earth. Some scientists believe that in some cases the dry valleys may soak up pollutants faster than pollutants enter them.

The Mona Lisa, one of the world’s most famous paintings, has been recreated with 3,604 cups of coffee—and 564 pints of milk. The different colors were created by adding no, little or lots of milk to each cup of black coffee.
The recreated Mona Lisa measured 20 feet long and 13 feet wide. It took a team of eight people three hours to complete the work. It was created for The Rocks Aroma Festival in Sydney, Australia, and seen by 130,000 people who attended the one-day coffee-lovers event.
Elaine Kelly, one of the organizers from the Sydney Harbor Foreshore Authority, was delighted with the result. She said, “Each coffee cup was filled with varying amounts of milk to create the different shades(色度) of the painting. We wanted to create an element of surprise and a sense of fun in the way we communicated with the public.”
“Once we had the idea of creating an image(像) out of coffee cups we searched for something iconic（有代表性的）to reproduce(复制).And after some time we chose the most iconic painting in history. The Mona Lisa has been reproduced so many times in so many different mediums but, as far as we know, never out of coffee,” Kelly continued. “Besides, the idea is practical.”
“It was fantastic. It really looked like the famous painting—the Mona Lisa. It was wonderful,” said one visitor.
After much planning it was great to see it coming together so well and the 130,000 people who attended the event certainly enjoyed it and were deeply attracted by it,” said Kelly.
1.How were the different colors of the recreated Moma Lisa created?
A.By adding different amounts of black coffee to each cup of milk.
B.By adding different amounts of milk to each cup of black coffee.
C.By using paints of different colors
D.By using different kinds of coffee
2.How large is the recreated Mona Lisa?
A. 20 square feet B. 260 square feet
C. 564 square feet D. 3,604 square feet
3.The people who saw the recreated Mona Lisa are all_______ lovers.
A.Mona Lisa B.milk C.coffee D.painting
4.The event organizers chose to recreate the Mona Lisa for the following reasons EXCEPT that _________ .
A. the Mona Lisa is a very iconic painting in history
B. the Mona Lisa has never been reproduced out of coffee
C. the idea can be actually carried out
D. it is very easy to do so
