There is a saying in French—“Si vieillesse pouvait, si jeunesse savait〞—which means roughly “if age had the ability, if youth had the knowledge〞．I was reminded of this saying the other day when I saw an interview with a distinguished Asian neurosurgeon (神经外科医生), now retired, about the impact of computer technology on modern surgery.
He was referring to the difficulty people of his age had in using the new techniques, but also to the fact that younger surgeons, who are more comfortable with the technology, lack some of the wisdom of experience.
It struck me that this problem is not just confined (局限于) to specialized fields such as medicine, but is widespread in modern life.There are many areas where the rapid growth of technology has widened the generation gap.
Young people are at ease with modern technology and propose all sorts of ways for using and developing it.But they often lack the experience needed to see further into the future to the possible dangers that a particular development may cause. Older people see all sorts of difficulties and dangers, but are sometimes ignored,
or even accused of being against progress, if they point out potential problems.Equally, they may see potential uses, but not have the technical skills to put them into practice themselves or the trust in the younger generation to do so.
Enthusiasm and inexperience come into conflict with caution and arrogance, usually with unsatisfactory results for both sides.
What is needed is the development of a partnership, based on mutual respect, which can deliver real progress by combining enthusiasm and caution in a constructive way, rather than in conflict with each other.The old need to give the younger generation the time, the resources and, above all, the authority to develop new ideas and use their skills.In exchange, the young need to turn more actively to the older generation to seek their advice and exploit their greater experience of the world in foreseeing and overcoming potential problems.
【语篇解读】本文以新老两代外科医生在一些方面的差异为例，阐述了这样一个观点：由于科技的飞速开展，许多领域中年纪大的人都不擅长学习新技术，而年轻人又缺乏一些经验。

因此，作者提出：年轻人应该多向年纪大的请教；年纪大的多给予年轻人时间和资源，最大程度上缩小新老两代之间的代沟和差距。

58．The passage is mainly about ________.
A．the impact of computer technology on modern surgery
B．an interview with a distinguished Asian neurosurgeon
C．new generation gap between the old and the young
D．a conflict between knowledge and experience
答案 C [主旨大意题。

本文主要表示了新老两代人在一些方面的代沟。

故答案选C。

] 59．What did the retired neurosurgeon probably mention in his interview? A．Old people's enthusiasm in obtaining new technology.
B．Old people's difficulty in using computers.
C．Young surgeons' bad manners in working.
D．Young surgeons' difficulty in getting experience.
答案 B [细节理解题。

第一段最后一句话与第二段中介绍的正是年纪大的人所缺少的，由此可知，年纪大的人在使用电脑方面有困难。

故答案选B。

]
60．In the writer's view, what advantage do the older generation have? A．They are happy with modern technology.
B．They are easy to learn new techniques.
C．They can foresee the future of the young generation.
D．They are rich in work experience.
答案 D [细节理解题。

根据第二段和第四段中的“experience〞可知，年轻人缺乏的经验正是年纪大的人所拥有的。

所以年纪大的人的优势就是他们拥有丰富的工作经验。

故答案选D。

]
61．What conclusion can be drawn from the last paragraph?
A．The young and the old should respect and learn from each other.
B．The young should teach the old modern technology.
C．The old should maintain their authority in every field.
D．The young and the old should work independently.
答案 A [段落大意题。

根据最后一段中的“What is needed is the development of a partnership，based on mutual respect〞以与后面的解释可知，年轻人和年纪大的人应该互相尊重、互相学习。

故答案选A。

Birds that are half­as leep—with one brain hemisphere(半球) alert and the other sleeping—control which side of the brain remains awake, according to a new study of sleeping ducks.
Earlier studies have documented half­brain sleep in a wide range of birds.The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves.The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere's eye stays open and alert.Birds also can sleep with both hemispheres resting at once.
Decades of studies of bird groups led researchers to predict extra alertness in the end­of­the­row sleepers which tend to be attacked more easily.Sure enough, the end birds tended to watch carefully on the side away from their companions.Ducks in the inner spots showed no preference for gaze direction.
Also, birds napping at the end of the line depend on single­hemisphere sleep，rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four­duck row, the researchers found that compared with 12 percent for birds in internal spots, outer birds half­asleep during some 32 percent of napping time.
“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain.〞 the researchers say.
The results provide the best evidence for a long­standing assumption that
single­hemisphere sleep evolved as creatures scanned for enemies.The preference for opening an eye on the lookout side could be widespread, he predicts.He's seen it in a pair of birds napping side­by­side in the zoo and in a single pet bird sleeping by a mirror.The mirror­side eye closed as if the reflection were a companion and the other eye stayed open.
Useful as half­sleeping might be, it's only been found in birds and such water animals as dolphins, whales, and seals.Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.
Studies of birds may offer unique insights into sleep.Jerome M．Siegel of the UCLA says he wonders if birds' half­brain sleep is “just_the_tip_of_the_iceberg〞．He supposes that more examples may turn up when we take a closer look at other species. 【语篇解读】本文是一篇科普文。

When I was 13，my bedroom walls were covered with posters of the Monkees and Beatles.I wrote fan letters and daydreamed about meeting the objects of my affections.I begged my parents to attend every rock concert and watch every TV show featuring my favorite celebrities；my friends and I discussed for hours all the things we would say and do when we met our favorite movie stars and pop singers.I drove my mother crazy！But after a few years，my obsession with stars faded as I matured and gained the confidence to socialize with“real〞 boys.
In the 35 years since I was a teenager，celebrity wo­rship(崇拜)has increased among teens due to the explosion of television celebrity gossip shows，and instant access to celebrity news on the Internet.It's no wonder that many teens are obsessed with stars when news programs are often filled with entertainment stories and the lives of celebrities.
Celebrity worship syndrome(综合征)is now con­sidered a personality disorder.While it is normal for teenagers to follow the lives of their favorite stars，parents should try to monitor everything their child finds interesting.Parents should take action if they suspect a teen is too obsessed with celebrities and showing little interest in school or withdrawing from the family.When teens talk a lot about celebrities and view them as just means of entertainment，this is considered normal celebrity worship.However，when a teenager。
