Snow Ranger
The two things – snow and mountains – which are needed for a ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain—often called "White Death."
It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937 –38 at Alta, Utah, in Wasatch National Forest.
This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a major ski area.
Thus, development of Alta and other major ski resorts in the west was dependent upon controlling the avalanche. The Forest Service set out to do it, and did, with its corps of snow rangers.
It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better.
He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. . The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down.
The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety for people on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, or talks with the ski area’s operator as he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes.
1. The snow rangers are employees of
A) the Forest Service.
B) the Resource Bureau.
C) the Tourist Board.
D) the Sports Bureau.
2.A snow ranger himself must be
A) a college graduate.
B) a physicist.
C) a geologist.
D) a mountaineer.
3. A snow ranger uses very powerful guns
A) to warn skiers of an approaching avalanche.
B) to signal for help in an emergency.
C) to create an avalanche.
D) to communicate with the ski area’ operator.
4. What is the primary duty of the snow ranger?
A) To make sure ski area operators are following safety rules.
B) To predict and control avalanches in mountainous areas.
C) To check skis and repair them.
D) To forecast the weather.
5.The passage implies that a snow ranger
A) knows how to use a pistol.
B) must write lengthy reports on his work.
C) may travel many miles when he is on duty.
D) has a long working day.

Don’t rely on plankton to save the planet
Encouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. ___1___.
Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. ___2___.
Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron for a month. ___3__.
In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere-- just 0.2 percent of the carbon dioxide humankind spews out each month.
Rough estimates in the past have predicted similarly disappointing results. __4__ Says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology. "But the take-home message is the same. ___5___."
A. Its opponents argue, however, that it will stop global warming.
B. Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.
C. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.
D. They found that 100 years later only between 2 and 11 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.
E. "These are newer and better models,"
F. Ocean fertilization is not the answer to global warming
