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 into the atmosphere — and yet that carbon dioxide will not contribute to global warming.
In a proposal by two scientists, vehicle emissions (排放) 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 (溶液) 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: 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 previous 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 analysis, 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 an idea. It has a couple of pieces to it that are interesting.”
67. What is the idea of the project being discussed in the article?
A. Recycling the carbon dioxide from cars back into gasoline.
B. Create a new gasoline that gives off very little carbon dioxide.
C. Using a special liquid solution to absorb carbon dioxide from cars.
D. Build synthetic fuel factories to remove carbon dioxide from the air.
68. What’s the name given to the new concept?
A. Synthetic Fuel.                                B. Green Freedom.    
C. Renewable Fuel.                               D. Carbon-dioxide-to-gasoline Factory.
69. Which of the following is NOT one of the benefits of this new concept as suggested in the article?
A. Reduction of global warming.           B. Cheaper gasoline for cars.
C. Longer life of cars.                    C. Less pollution of the atmosphere.
70. What’s the biggest problem in realizing the concept according to the report?
A. Shortage of starting funds.        B. Immature technology involved.
C. All previous similar attempts have failed.
D. The use of too much energy in running the fuel factory.

For many people today, reading is no longer relaxation.

In  1  a job or advancing in one, the ability to read and comprehend  2   can mean the difference between success and failure. Yet the unfortunate fact is that most of us are   3   readers. Most of us develop poor reading  4    at an early age, and never get over them. The main deficiency   5  in the actual stuff of language itself ——words. Taken individually, words have  6   meaning until they are strung together into phrases, sentences and paragraphs.    7  , however, the untrained reader does not read groups of words.

The city of Rome has passed a new law to prevent cruelty to animals. All goldfish bowls are no longer allowed and dog owners must walk their dogs.
This comes after a national law was passed to give prison sentences to people who desert cats or dogs.
“The civilization of a city can be measured by this,” said Monica Cirinna, the councilor (議員)behind the new law.
“It’s good to do whatever we can for our animals who in exchange for a little love fill our existence with their attention,” she told a Rome newspaper.
The newspaper reported that round bowls don’t give enough oxygen for fish and may make them go blind.
“Rome has tried to protect fish more than anywhere else in the world. It stands out for recognizing that fish are interesting animals who deserve our respect and compassion every bit as much as dogs and cats and other animals,” said Karin Robertson, a director of the People for the Ethical Treatment of Animals.
Last year a law was passed in Italy that gives people who desert pets big fines and prison sentences. Since then local governments have added their own animal protection rules.
The northern city of Turin passed a law in April to give pet owners fines of up to $598 if they do not walk their dogs three times a day.
The new law in Rome also says that owners mustn’t leave their dogs in hot cars or cut their dogs’ tails to make them look lovelier. The law also gives legal recognition to the “cat ladies” who feed homeless cats. The cats live all over the city from ancient ruins to modern office car parks.
