In Stockholm, the Swedish Academy has chosen the British author Doris Lessing for the 2007 Nobel Prize in Literature.

The selection of Doris Lessing for a Nobel was popular among the hundreds of journalists gathered for the announcement in Stockholm.

Permanent Secretary of the Swedish Academy Horace Engdahl said with skepticism, fire and visionary power Lessing has subjected a divided civilization to scrutiny.

Doris Lessing was born in 1919 in Persia - modern-day Iran - to British parents, moving as a child with her family to southern Rhodesia, now Zimbabwe, where she stayed in school only to the age of 14.

A year after moving to London, she published her first novel in 1950. The Grass is Singing examines unbridgeable racial conflict in colonial Africa through the eyes of a white farmer's wife and her black servant.

A member of the British Communist Party during the 1950s and a campaigner against nuclear arms and South African apartheid, Lessing was for years banned from that country and from Rhodesia.

Her literary breakthrough came in 1962 with publication of The Golden Notebook, seen by many, though not necessarily Lessing, as a pioneering work of modern feminism. A disjointed study of the mind of the main character, Anna Wulf, the novel explores her thoughts about Africa, politics and communism, relationships with men and sex, and Jungian analysis and dream interpretation.

Lessing's themes shifted to psychology in her works from the 1960s, and by the 1970s she was fascinated with the Islamic mystic tradition of Sufism. Her turn toward science fiction with the Canopus series in the early 1980s was not warmly received by traditionalist critics, but she has continued to win new readers and numerous literary awards, including the David Cohen British Literary Prize and the Companion of Honour from the Royal Society of Literature, both in 2001.

Following the announcement, the Horace Engdahl told VOA why he was personally so pleased with Lessing's selection.

"She is one of the truly great writers - of novels, short stories, fiction and non-fiction," Engdahl said. "She is one of the few writers who have had the courage to uphold the principle of equality between the male and female experience, and she has given the impulse to numbers of other women writers. And she is really the mother of a school that is one of the most important in our contemporary literature."

At 87, Doris lessing is the oldest Nobel Literature laureate since the first prizes were awarded in 1901. Each Nobel Prize is this year accompanied by a check for approximately $1.4 million.

41. How old was Doris Lessing when she published her first novel?

A. 14            B. 26           C. 31                D. 50

42. Which of the following about The Grass is Singing is true?

A. It is mainly about racial conflict between the whites and the blacks in the US.

B. The main characters are a white farmer’s wife and her black servant.

C. It was published in Africa.

D. It was Doris Lessing’s most famous novel.

43. We can infer from the passage that __________.

A. Journalists are very interested in the election of Doris Lessing’s for Nobel Prize.

B. Doris Lessing regard The Golden Notes as a pioneering work of feminism.

C. Doris Lessing has written about many different subjects.

D. Many writers have the courage to stick to the equality between the male and female experience.

44. The underlined word school in the last paragraph but one means________.

A. institution for educating children

B. college or university

C. department of a university 

D. group of writers, thinkers

45. Which of the following can be the best title of this passage?

C. The oldest Nobel Prize winner

D. 2007 Nobel Prize announced in Stockholm

阅读下面短文,回答下 * * 道题

要说清楚纳米科技的真正涵义不是一件易事。“纳米”只是一个长度单位,大约是10个氢原子排列起来的长度。纳米科技被广泛地定义为纳米尺度空间(如从一纳米至几百纳米)的科学技术。当科学家和工程技术人员力图在用纳米尺度来理解和控制物质的时候,就会发现许多新的现象,发明许多新的技术。用纳米颗粒粉体制成的纳米材料或具有纳米尺度晶粒的材料会显示出比一般材料更优异的性能。光刻技术的不断进步,已经使芯片的制造技术正在接近或达到100纳米,使计算机的速度越来越快,而体积越来越小。这些科技进步对工业技术发展和社会进步都具有重要意义。然而,这并不是科学家们正在探索研究的纳米科技的核心和本质,这一切不过都是传统显微加工技术的扩展和延伸而己。它们都是通过采用类似于车床、铣床、钻床等加工设备,通过“切削”材料加工成所需的产品。这种技术统称为“由上到下”或“由大到小”的加工技术。纳米科技的核心和本质在于人们创造物质的生产方式将完全不同于自石器时代以来人类用工具创造物质世界的方式,而决不仅仅是一个长度单位所能涵盖的。纳米科技决不意味着制造纳米尺度的产品,纳米产品可以小到分子尺度,大到汽车、飞机,只是制造的方式完全不同罢了。

要理解纳米技术的真正涵义还须从纳米技术思想的起源开始。纳米技术的灵感来自于已故美国物理学家查理。范曼的演讲,他在1959年向加州理工学院的同事们提出了一个新的想法。从石器时代开始,人类从磨尖箭头到光刻芯片的所有技术,都与一次性地削去或者融合数以亿计的原子以便把物质做成有用的形态有关。范曼质问道,为什么我们不可以从另外一个角度出发,从单个的分子甚至原子开始进行组装,以达到我们的要求呢实际上这一灵感来自于大自然从单个分子,甚至单个原子创造物质的启示。如果把人体分解成组成它的基本单元,我们获得的将是一小桶的氧、氢和氮,一小堆碳、钙和盐,微量的硫、磷、铁和镁,以及微不足道的 20种或更多的其他化学元素。它们的总价值可以说是微不足道的。然而,大自然就是采用它们自己的、科学家们称之为纳米工程的方法,把这些廉价的、丰富的、无生命的单元转成具有白生成、自维持、自修复、自意识能力的生灵,可以行走、扭动、游泳,具有嗅觉和视觉,甚至可以思想和做梦,其价值无与伦比。因此,纳米技术就是向大自然学习,力图在纳米尺度精确操纵原子或分子来制造产品的技术,统称为“由底向上”或“由小到大”的加工技术。

科学家们已经或正在意识到纳米科技将给人类带来的社会变革。由于可能通过精确地控制原子或分子制造新产品,生产过程将变得非常清洁,将不产生副产品和废物。纳米技术将采用资源丰富的元素来制造完美的金刚石材料,不仅强度会比钢高几十倍,而且重量仅是钢的几十分之一。利用纳米技术,人类有可能在原子和分子尺度诊断和治愈疾病,甚至修补细胞。纳米技术将可以制造分子开关和导线,从而将导致一场计算机制造技术的革命。

(节选自张永刚《纳米科技的迷雾》)

根据本文提供的信息,以下推断正确的一项是()。

A.人类已能借助纳米技术,在原子和分子尺度诊断和治愈疾病,修补细胞

B.人类尚未觉悟到纳米科技给人类带来的社会变革

C.纳米科技纯粹是科学幻想,而制造芯片的光刻技术永远也不会寿终正寝

D.随着纳米技术的发展,将来能用空气中的二氧化碳所含的碳原子作原料来制造金刚石
