If two scientists at Los Alamos National Laboratory are correct, people will still be driving gasoline-powered cars 50 years from now, giving out heat-trapping carbon dioxide(二氧化碳) into the atmosphere-and yet that carbon dioxide will not contribute to global warming.
In a proposal by two scientists, vehicle emissions(排放物) would no longer contribute to global warming. The scientists, F. Jeffrey Martin and William L. Kubic Jr., are proposing a concept, which they have named Green Freedom, for removing carbon dioxide from the air and turning it back into gasoline.
The idea is simple. Air would be blown over a liquid solution of potassium carbonate, which would absorb the carbon dioxide. The carbon dioxide would then be put to chemical reactions that would turn it into fuel(燃料): gasoline or jet fuel.
This process could change carbon dioxide from an unwanted, climate-changing pollutant into a vast resource for renewable fuels. The cycle-equal amounts of carbon dioxide produced and removed-would mean that cars, trucks and airplanes using the synthetic(合成的) fuels would no longer be contributing to global warming.
Although they have not yet built a synthetic fuel factory, or even a small model, the scientists say it is all based on existing technology. “Everything in the concept has been built, is operating or has a close cousin that is operating,” Dr. Martin said.
The Los Alamos proposal does not go against any laws of physics, and other scientists who have independently suggested similar ideas. Dr. Martin said he and Dr. Kubic had worked out their concept in more detail than former proposals.
There is, however, a major fact that explains why no one has built a carbon-dioxide-to-gasoline factory: it requires a great deal of energy.
According to their explanation, their concept, which would cost about $5 billion to build, could produce gasoline at an operating cost of $1.40 a gallon and would turn economically practical when the price at the pump hits $4.60 a gallon.
Other scientists said the Los Alamos proposal perhaps looked promising but could not evaluate it fully because the details had not been published. “It’s definitely worth pursuing,” said Martin I. Hoffert, a professor of physics at New York University. “It’s not that new. It has a couple of pieces to it that are interesting.”
1.What is the value of the scientists’ proposal
A.It increases the productivity of a fuel factory.
B.It decreases the cost of producing gasoline.
C.It reduces the pollution caused by car driving.
D.It promotes a new idea of environmental protection.
2.The underlined part “has a close cousin that is operating” probably means the technology in the concept .
A.has been popular for so long
B.has been ignored by many people
C.is not appropriate for practice
D.will be put into practice in the near future
3.What is the biggest challenge in realizing the concept Green Freedom
A.There is no theoretical basis.
B.It is not economically practical.
C.There is no solution to some technical problems.
D.Only a few scientists support the idea.

The history of writing instruments,with which humans have recorded and conveyed thoughts and feelings,is the history of civilization itself.This is how we know about our ancestors and their life.
The handy sharpened-stone was adapted into the first writing instrument.Around 24,000 BC,the cave man started drawing pictures with the stone onto the walls of his cave. 1 Walls at the Apollo site in Namibia are believed to be the oldest rock paintings to date.
Before paper came along,people used clay or wax tablets on which they wrote with sharp objects such as metal sticks or bones.Around 6,000 years ago,the Egyptians invented the first paper-like material called papyrus.The word “paper” actually comes from the word “papyrus”.
2 Bones or metal sticks were no longer useful as the papyrus could not be scratched.So the Egyptians created a reed-pen perfect for the papyrus. 3 And thus,ancient Egyptians transformed bamboo stems (茎) into an early form of a fountain pen.
Another writing instrument that remained active in history for a long period was the quill (鹅毛) pen.Introduced around 700 AD,the quill was a pen made from a bird feather.Goose feathers were most common. 4 For making fine line drawings,crow feathers were the best.
When writers had better inks and paper and handwriting had developed into both an art form and an everyday occurrence,man’s inventive nature once again turned to improving the writing instrument. 5
A.Now something was needed to write upon the papyrus.
B.The papyrus became the most popular material at that time.
C.Swan feathers were of high quality,being rare and most expensive.
D.Bamboo stems were better and much more expensive than goose feathers.
E.This led to the development of the modern fountain pen in the 19th century.
F.These were mostly the stems of grass,especially from the bamboo plant.
G.These drawings showed events in daily life like the planting of crops or hunting victories.
