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.”

Boxing was long viewed sickly. Generally forbidden by law in earlier days, the fighting was usually done with bare fists, and matches often lasted forty or fifty rounds.
In 1882 John L. Sullivan, a fighter of great power, won the world heavyweight championship from Paddy Ryan in a bare fisted battle marked by hitting, scratching, and biting without any rule. Five years later, while fighting Patsy Cardiff at Minneapolis, Sullivan broke his right arm in the third round, but he continued fighting to the sixth round and won. In 1889, Sullivan defeated Jade Kilrain with his bare fists in another championship fight, winning twenty thousand dollars and a diamond prize medal. His admirers talked then of running him for the next governor, but he traveled to Australia for a boxing tour instead, coming back only to lose his title in a twenty-one-round match with a young Californian named James J. Corbett.
“Gentleman James” victory in this match marked a turning point, for it showed scientific boxing was over strength. But Corbett’s title ended in 1897, when another boxer, Bob Fitzsimmons, in less than three seconds, achieved his feats and then Fitzsimmons knocked out an Irishman, won the heavyweight championship of the world, and invented the terrible “solar plexus punch.”

If you travel around the world , you will be surprised to find just how different the foreign customs can be from your own .
A visitor to India would do well to remember that people there consider it impolite to use the left hand for passing food at table . The left hand is supposed to be used for washing yourself . Also in India , you might see a man apparently shaking his head at another and assume that he is disagreeing . But in many parts of India a shake of the head is a gesture that shows agreement of acceptance .
Nodding your head when offered a drink in Bulgaria is likely to leave you thirsty . In that country you shake your head to indicate “yes” —a nod indicates “no”. The Arabs are known for their hospitality . At a meal in countries on the Arabic Peninsula , you will find that any drinking vessel （容器，器皿）is repeatedly refilled as soon as you drink it up .
In Europe it is quite usual to cross your legs when sitting talking to someone , even at an important meeting . Doing this when meeting an important person in Thailand , however , could cause offence . It is too informal an attitude for such an occasion . Also when in Thailand you are not supposed to touch the head of an adult —it’s just not done . In Japan , it is quite usual for men to plan evening entertainments for themselves and leave their wives at home . In Europe such attitudes are disappearing .
Customs vary from country to country . Visitors may be at a loss as to what to do in a foreign environment . In such circumstances , the golden rule to follow is : When in Rome , do as the Romans do .

A．Thailand B．India C Arabic peninsula D．Bulgaria

When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm, in the winter especially, we wear quite out off from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that my life has its, too.
One big disadvantage is money. It costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma (哮喘), and the air is so that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.
Of course there are advantages. First, there is so much to do in the city, whatever you tastes in culture or entertainment. Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising --- and, what is more, shops are often only a short walk away.
Is life better then, in the city? Perhaps it is , when you are in your teens or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem preferable. I certainly hope to move back there soon.
