单选题The use of nitrous oxide, or laughing gas during childbirth fell out of favor in the United States decades ago, and just two hospitals—one in San Francisco and one in Seattle—still offer it. But interest in returning the dentist office staple to the delivery room is growing: respected hospitals including Dartmouth-Hitchcock Medical Center plan to start offering it, the federal government is reviewing it, and after a long break, the equipment needed to administer it is expected to hit the market soon. Lori Rowell, due to give birth to her second child in June, is interested in the option. "I would definitely think about it, and read about and talk to my doctor about it," said Rowell, 36, of Concord. "It is nice to know that it doesn"t affect the baby." Though laughing gas is commonly used for labor pain relief in Canada, Great Britain and other countries, it"s been all but abandoned in the United States in favor of other options, said Judith Bishop, a certified nurse midwife at the University of California San Francisco Medical Center and leader in the effort to reintroduce laughing gas for labor. "In this country, most people when they hear about laughing gas, they think it sounds pretty retro (重新流行的), that it sounds very old-fashioned and they"re sure there"s something bad or dangerous about it and we must"ve chosen to eliminate it. But I think we eliminated it because we went for the more specialized, higher-tech options," said Bishop, who will be among the speakers Monday at a conference for New Hampshire, Vermont and Maine hospital officials. She and other advocates of reintroducing laughing gas emphasize that it is no silver bullet—it "takes the edge off" pain rather than eliminates it. But they say it should be among the options offered to women, particularly those who give birth at small or rural hospitals that lack round-the-clock anesthesiologists (麻醉师). Laughing gas is easy for women to self-administer, takes effect quickly, and can be used late in labor. "It"s not fight for everybody, but it"s something that for many women will offer a certain amount of relief," Bishop said.

单选题{{B}}TEXT B{{/B}} Is it possible to persuade mankind to live without war? War is an ancient institution which has existed for at least six thousand years. It was always bad and usually foolish, but in the past the human race managed to hive with it. Modern ingenuity has changed this. Either Man will abolish war, or war will abolish Man. For the present, it is nuclear weapons that cause the most serious danger, but bacteriological or chemical weapons may, before long, offer an even greater threat. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do {{U}}this{{/U}}, we need to persuade mankind to look upon international questions in a new way, not as contests of force, in which the victory goes to side which is most skillful in killing people, but by arbitration in accordance with agreed principles of law. It is not easy to change very old mental habits, but this is what must be attempted. There are those who say that the adoption of this or that ideology would prevent war. I believe this to be a big error. All ideologies are based upon dogmatic statements which are, at best, doubtful, and at worst, totally false. Their adherents believe in them so fanatically that they are willing to go to war in support of them. The movement of world opinion during the past few years has been vary largely such as we can welcome. It has become a commonplace that nuclear war must be avoided. Of course very difficult problems remain in the world, but the spirit in which they are being approached is a better one than it was some years ago. It has begun to be thought, even by the powerful men who decide whether we shall live or die, that negotiations should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important conflict nowadays is not between different countries, but between Man and the atom bomb.
