问答题For the first time in decades, doctors have begun making major changes in the treatment of lung cancer, based on research proving that chemotherapy can significantly lengthen life for many patients for whom it was previously thought to be useless. The shift in care applies to about 50,000 people a year in the United States who have early cases of the most common form of the disease, non-small-cell lung cancer, and whose tumors are removed by surgery. (46) Many of these patients, who just a few years ago would have been treated with surgery alone, are now being given chemotherapy as well, just as. it is routinely given after surgery for breast or colon (结肠)cancer. The new approach has brightened a picture that was often bleak. "The benefit is at least as good, and maybe better than in the other cancers," said Dr. John Minna, a lung cancer expert and research director at the University of Texas Southwestern Medical Center in Dallas. He said new discoveries were helping to eliminate doctors' "nihilistic" attitudes about chemotherapy for lung cancer. "The standard of care has changed," said Dr. Christopher G. Azzoli, a lung cancer specialist at Memorial Sloan-Kettering Cancer Center in New York. (47) A major impetus for the change came a year ago, when two studies presented at a cancer conference showed marked increases in survival in patients who received adjuvant (辅助的)chemotherapy, meaning the drugs were given after surgery. In one study of 482 patients in Canada and the United States, led by Dr. Timothy Winton, a surgeon from the University of Alberta, 69 percent of patients who had surgery and chemotherapy were still alive five years later, as compared with 54 percent who had just surgery. The patients were given a combination of two drugs, cisplatin and vinorelbine, once a week for 16 weeks. In the world of lung cancer research, a survival difference of 15 percentage points is enormous. (48) Overall, the patients given chemotherapy lived 94 months, versus 73 months in those who had only surgery—also a huge difference in a field in which a treatment is hailed as a success if it gives patients even three or four extra months. A second study, also announced at the conference last year, had similar findings, and so did a third, presented just a month ago at the annual meeting of the same cancer group, the American Society of Clinical Oneology. At major medical centers, doctors quickly began to put the results into practice. (49) "The findings were so stunning from these studies a year ago that they began to change the standard of care," said Dr. Pasi Janne, a lung cancer specialist at the Dana Farber Cancer Institute in Boston. "Over the last year, the number of patients we've had referred here for adjuvant chemotherapy has gone up steadily." (50) But some doctors hesitated to make changes, Dr. Winton said, wanting first to see the studies published in a medical journal, which would mean the data had stood up to the serutiny(仔细的检查) of editors and expert reviewers. Now, his study has become the first of the three to pass that test. It is being published today in The New England Journal of Medicine, along with an editorial by Dr. Katherine M. S. Pisters, a lung cancer specialist at the m. D. Anderson Cancer Center in Houston.

问答题我一直认为,真正的哲学应该是创造性的。一个哲人有时可能会写一点笔记,不时还要编些史料,但其根本必须是说出别人没有想到或想到而说不出来的东西。所以,衡量哲学家的唯一尺度,只能是看他是否向人类思想宝库提供了什么有价值的论见。此乃学术正果。 2.在先秦时期的百家争鸣中,道家虽没有儒家和墨家那样众多的徒属,以及显学的地位,但这个学派对宇宙、社会和人生的独特领悟,却是其他各家所不能取代的。正因为如此,在历史的发展中,道家才呈现出永恒的价值与生命力。 3.你们都多次听说过,科学家是用归纳法和演绎法工作的,他们用这些方法,力求从自然界找出某些自然规律,然后根据这些规律,用某种非同一般的本领,建立起他们自己的理论。 4.语言是人类社会所特有的一种信息系统,它的传递与接受总是在现实环境中发生的,并受到现实环境的影响和支配,这种现实环境是人们进行社会交际的基础,社会中凡是使用语言的人每次都是在特定的环境中实现交际的。具体地说,它就是说话或写作的社会环境、自然环境、作品的上下文、说话的前言后语等等。我们称之为语言环境,简称语境。 5.他是现代语言学的奠基人,是他重新组织起对语言和语言本质的系统研究,并提出语言研究的新视角、新方法和新方向;是他使20世纪的语言学取得了如此伟大的成就,他也因此成为举世公认的了不起的现代思想家。让我们记住他的名字——索绪尔 (Saussure)。

问答题The old lady had always been proud of the great rose-tree in her garden, and was fond of telling how it had grown from a cutting she had brought years before from Italy, when she was first married. She and her husband had been travelling back in their carriage from Rome (it was before the time of railways) and on a bad piece of road south of Siena they had broken down, and had been forced to pass the night in a little house by the road-side. The accommodation was wretched of course; she had spent a sleepless night, and rising early had stood, wrapped up, at her window, with the cool air blowing on her face, to watch the dawn. She could still, after all these years, remember the blue mountains with the bright moon above them, and how a far-off town on one of the peaks had gradually grown whiter and whiter, till the moon faded, the mountains were touched with the pink of the rising sun, and suddenly the town was lit as by an illumination, one window after another catching and reflecting the sun's beam, till at last the whole little city twinkled and sparkled up in the sky like a nest of stars.
