　　Many experts complain that media (傳媒) too often take advantage of the science fiction (科幻小說) aspects of nanotech (納米技術(shù)) . Reports of nanotech often refer to K. Eric Drexler's book Engines of Creations , which predicts an age full of dominant molecular(分子的) manufacturing and a world without material scarcity (短缺) . Whatever humans need will one day be built cheaply with microscopic self-replicating machines (精微自我復(fù)制機(jī)) , that put atoms together to create copies of anything alive in the world-from trees to human bodies.

　　In fact, the scientific community is deeply divided over whether self-replicating machines ere possible. If they are, major dangers could exist. Dr. Drexler himself thought that self-replicating machines could go out of control . He writes in his book that man-made “plants” with leaves no more efficient than today's solar cells could win over real plants crowding the earth with leaves that are not suitable to be eaten. Tough “bacteria (細(xì)菌)” could be more competitive than the real bacteria. They could spread everywhere, replicate swiftly, and reduce the earth to dust in a matter of days.

　　Critics of nanotech have made use of such images, calling for a delay on commercial (商業(yè)的) nanotech until regulations (法規(guī)) are established. They also point to the possible military uses of nanotech. Bill Jay , the co-founder of Sun Microsystems, wrote in a Wired magazine essay in 2000 that if nanotech falls into the wrong hands, it could bring dangers to society.

　　Opponents say Mr. Joy is over-reacting, “In a way, calling for bans on research into molecular manufacturing is like calling for a delay on faster than-light travel because no one is dong it. ” says Glenn Reynolds, a University of Tennessee law professor.

　　Professor Reynolds says it is a good idea to regulate nanotech, but in ways the government would regulate any that could be dangerous. Expert controls and certification systems for nanotech companies are examples. US lawmakers have put forth four bills (法案) on nanotech research and development.

1．K. Eric Drexler in his book predicts a future world with sufficient material, because ________.

[　　]

A．man-made plants could replace real plants and grow more quickly

B．plants produced by nanotech would be as sufficient as today's solar

C．man-made bacteria would be wide-spread and capable of self-replicating

D．humans could create copies of anything alive with high technology

2．To call far a delay on commercial nanotech, critics of nanotech make use of ________.

[　　]

A．current social problems

B．science fiction descriptions

C．disagreements in the scientific community

D．the fact that no one is doing molecular manufacturing

3．Opponents of Bill Joy would NOT agree to ________.

[　　]

A．control nanotech expert

B．ban nanotech research to avoid any possible dangers

C．put forth bills on nanotech research and development

D．establish a certification system for nanotech companies

4．Which of the following is the main idea of the passage?

[　　]

A．Nanotech should not be put into wrong use in the military field.

B．The government should regulate products that could be dangerous.

C．Nanotech regulations should be established in spite of the divided opinions.

D．The media should not take advantage of the science fiction aspects of nanotech.

答案：D;B;B;C
解析：

　　1．D　導(dǎo)解：第一段說有了自我復(fù)制機(jī)之后，人類需要的任何東西都可以廉價(jià)再造．

　　2．B　導(dǎo)解：第三段首句的such images指的是前面提到的納米技術(shù)科幻般的功能，比如plants，bacteria，因此選B．

　　3．B　導(dǎo)解：最后兩段提到反對(duì)派的言行，從中可知 A，C，D項(xiàng)均在其列，只有B項(xiàng)是他們反對(duì)的，說這好比推遲旅行．

　　4．C　導(dǎo)解：全文提到兩種觀點(diǎn)并進(jìn)一步闡述，從中可知他們都認(rèn)為應(yīng)該有法規(guī)約束這件事，C是全文中心議題．

A Giant Leap for China

　　A few days ago, he was just Colonel(上校)Yang; few people knew his name or recognized his face．But last Thursday, when he came back to the earth after a 21-hour trip to space, Yang Liwei’s smile was seen across the world above the magic words：“China’s first spaceman”．

　　The 38-year-old astronaut was sent into space at 9 a. m．Last Wednesday by China’s Shenzhou Ⅴ spacecraft, which orbited the earth 14 times．He landed safely at 6∶23 a. m．The next day, making China the third country successfully send a person into space, after the former Soviet Union and the US．

　　Yang was satisfied with his job．“I have seen many landing scenes before on video, and I think ours was one of the most successful, ”He said on a special plane to Beijing after landing．Born into an ordinary family in Liaoning Province, he became a pilot in the Chinese Air Force in 1987, spending 1350 hours in the air．He joined the Chinese space programme 11 years later．

　　While in space, Yang recorded everything he saw as well as showing China’s national flag and the United Nations’ flag to the people watching on TV at home．He also ate a meal of diced chicken and fried rice, before taking a 3-hour nap．The whole project went according to plan, but space exploration is not as easy as it seems．

　　Anyone who saw the destruction of the US space shuttle Columbia in February this year will know that Yang took a great risk．

　　He experienced extremely high temperatures, while the gravitation(重力)on take-off and landing were strong enough to force tears from his eyes．

　　He has spent five years training to become a spaceman．

　　“I eat all of my meals at the space programme’s dinning room and have never been able to take my son to kindergarten, ”he said．“I’ve never met his teachers．”

　　But becoming China’s first spaceman has made all the effort worthwhile．

　　“When I boarded the spacecraft for the first time, I couldn’t help feeling excited,” he said．“I decided that I had to fly it．”

　　To Chinese people, Yang is now a hero．One visitor to a Xinhua news agency online forum(網(wǎng)上論壇)said, “Yang’s trip is a giant leap forward for China．”

　　Officials say the next Shenzhou will be launched by 2005．China also plans to develop spacewalking and a space lab．

閱讀理解

　　The repairman told me, “No charge, Professor Pan! We’re friends．”

　　“I’d rather pay, ” I replied．“If it’s free, I can’t afford it!”

　　Chinese often refuse payment for professional services, insisting, “We’re friends now!” But then they show up later to ask me to tutor them in English, or get them into an American university, and I wish I’d have just paid the 30 yuan I owed them in the first place!

　　According to the Americans, “There is no free lunch．”, means that there’s a price for everything．And I’m always looking around to figure out what this means．

　　Many of our neighbours have given us fruit or flowers or costly teas, never asking anything in return．For years, a bicycle repairman has repeatedly refused to let me pay him．“Wait until you have something major to fix!” he insists．

　　I mentioned to a peasant friend that I wished I had a stone mill to grind(磨)flour for bread．A month later he showed up with a beautiful mill that he’d had his uncle in the countryside carve from a solid block of granite(花崗石)．

　　Chinese generosity(慷慨)is a real education for Americans　like me, who would rather avoid social entanglements(糾紛)and just hand over the money．But cash can’t compensate(補(bǔ)償)for the greatest gift－friendship．

　　When an American saw some of my friends sitting on bamboo stools under the trees, sipping(呷)tea, he said, “They must have nothing better to do．” “Actually,” I said, “they are professors, with plenty to do．But probably you are right in saying that, at this moment, they have nothing better to do．And neither do I!”?

　　And I joined the group．When chatted about tea and Chinese cooking and how much my boys have grown since we arrived．One man said, “They were pocket-sized when you came here．Now they’re taller than you．How time flies!”

　　How life flies．And Chinese are smart enough to share what they know they cannot keep．They freely give off their time, never too busy to help a friend．And they are teaching me, slowly, to both give and receive．So the next time someone says, “No charge．We’re friends!” I will thank them heartily．But if they show up later asking me to tutor them in English, I’ll make sure they tutor my son in Chinese as well, because there’s still no free lunch．

(1)

Why did the author insist paying the repairman while he was offered free repairs?

[　　]

A．

Because he was an upright man．

B．

Because he didn’t know the repair man．

C．

Because he thought it natural to pay for other’s service．

D．

Because he didn’t want to help others in return．

(2)

Generally, the author thinks that ________．

[　　]

A．

Chinese are generous and always ready to help their friends

B．

Chinese are good at exchange of equal values

C．

Chinese are free enough to drink and chat with their friends

D．

Chinese are helpful but don’t treasure time

(3)

The best title for the passage should be “________”．

[　　]

A．

Still No Free Lunch

B．

A Good Lesson From Chinese

C．

True Help Or Not

D．

Learn To Both Give And Receive

(4)

Which of the following is TRUE?

[　　]

A．

All the Chinese that once gave the author help have asked him to tutor them in English．

B．

When a peasant knew the author needed a mill, he made one for the author himself．

C．

The author thinks that Chinese are wise enough to enjoy the limited life．

D．

The author is not used to the Chinese ways to make friends．

　　Mianzi(literally “face”)has long been observed by most Chinese．As a famous saying goes, “Men live for face as trees grow for bark．”

　　In a recent survey conducted by China Youth Daily, over 93 percent of the polled(接受測試的)people(1150)said they pay much attention to their mianzi, which concerns people’s decency, personality, and dignity．

　　When asked what the most humiliating(不光彩的)thing is, a heavy number accounting for 74.9 percent of the total chose public gaffes(失態(tài))with the failed fulfillment of one’s promise coming in as second．More than a half of the people feel ashamed of being shown as ignorant before others．A total 47.5 percent of the polled considered it a loss of face to have no enough money on them when treating friends out to a dinner．

　　What would enhance one’s face then? In a ranking on this question, the survey revealed that doing what others cannot do topped the list, taking up a high proportion of 83.7 percent．Following at the second, with 53.9 percent, was being praised in public．Being outstandingly knowledgeable was third on the list for sharpening one’s mianzi, accounting for 51.7 percent．

　　According to the survey, face usually comes at a price．To pay or not to pay, it’s a problem．Deeply troubled with the face concept, many “fight” each other for the chance to foot the bill despite a barren pocket．Some 80.7 percent of those taking the poll thought it a tough life to always hold the face concept．Surprisingly, only 8.7 percent of the polled insisted that it tarnish(損害)a man’s authority and face in a family where the wife is the major breadwinner．

　　Armed to the teeth with the luxury name brand clothes, a limited 7.7 percent among all the polled prefer pricey cloths in order to gain more face．

　　Taking the social status into consideration, 82.9 percent of the polled nod at the opinion that those holding a superior position care far more than the general public about face．In another comparison, the manual labors pay less attention to face than brainworkers．The survey also revealed that men focus more on face than women and the senior more than the young．

　　While most people hold a neutral viewpoint about those who value mianzi a lot, nearly 80 percent of all the polled are willing to make friends with them．

(1)

According to the survey, which of the following most enhances one’s face?

[　　]

A．

Having enough money to treat friends out to a dinner．

B．

Being praised by others in public．

C．

Doing what others can’t．

you made a big mistake in your speech to the public

C．

you let out that you know little about what your friends are talking about

D．

A．

A young brainworker．

B．

A senior manual laborer．

　　The age of wealthy youth is over．Today's under-thirties are the first generation for a century who can expect a lower living standard than their parents．

　　Research into the lifestyle and prospects of people born since 1970 shows that they arelikely to face a lifetime of longer working hours, lower job security and higher taxes than the previous generation．

　　When they leave work late in the evening they will be more likely to return to a smallrented flat than to a house of their own．When, eventually, they retire it will be on pensions(養(yǎng)老金)far lower in real terms than those of their immediate ancestors．

　　The findings are revealed in a study of the way the ageing of Britain's population isaffecting different generations．

　　Anthea Tinker, professor of social gerontology at King's College London, who carried out much of the work, said the growth of the proportion(比例)of people over 50 had reversed the traditional flow of wealth from older to younger generations．

　　“Today's older middle-aged and elderly are becoming the new winners,” she said．“Theymade relatively small contributions in tax but now makerelativelybigclaimsonthe welfare system．Generations born in the last three to four decades face the prospect of handing over more than a third of their lifetime's earnings to care for them”．

　　The growing number of older people, many living alone, has also increased demand forproperty and pushed up house prices．While previous generations found it easy to raise a mortgage(抵押), today's under-thirties have to live with their parents or rent．If they can afford to buy a home it is more likely to be a flat than a house．

　　Laura Lenox-Conyngham, 28, grew up in a large house and her mother did not need to work．Unlike her wealthy parents, she graduated with student and postgraduate loan debts of ￡13, 000．She now earns about ￡20,000 a year, preparing food to be photographed for magazines．Her home is a one-bedroom flat in central London and she rents the lounge sofa-bed to her brother．

　　“My father took pity and paid off my student debts,” she said．“But I still have no pensionand no chance of buying a property for at least a couple of years－and then it will be some-thing small in a bad area．My only hope is the traditional one of meeting a rich man．”

　　Tinkers research shows Lenox-Conyngham is representative of many young professionals, especially in London, Manchester, Edinburgh and Bristol．

(1)

By saying “the growth of the proportion of people over 50 had reversed the traditional

flow of wealth from older to younger generations”(Lines 23, Para．5), Anthea Tinker

really means that ________．

[　　]

A．

currently wealth flows from old generation to younger generation

B．

traditionally wealth flows from younger generation to old generation

C．

with the increasingly big population of over 50, the trend arises that wealth flows

from younger generation to old generation

D．

with more and more people of over 50, traditions have been reversed

(2)

Why are today's older middle-aged and elderly becoming the new winners?

[　　]

A．

Because they made relatively small contributions in tax, but younger generation will possibly hand over more than a third of their lifetime's earnings for the care of them．

B．

Because they contributed a lot in tax and now can claim much on the welfare system．

C．

Because they made small contributions, but now can make money easily．

D．

Because they outnumber(在數(shù)量上超過)younger generation and enjoy more privileges in the present society．

(3)

Which factor pushed up house prices?

[　　]

A．

Many young men, who live alone, have increased demand for houses．

B．

Many young men need to rent more houses．

C．

It is easy to apply for a mortgage for young generation．

D．

The number of older people, many of whom live alone, becomes bigger and bigger．

(4)

We can conclude from the passage that ________．

[　　]

A．

today's under-thirties are leading a miserable life in Britain

B．

Laura Lenox-Conyngham's attitude to work and life represents that of many young professionals in Britain

C．

life can get harder for under-thirties in Britain

D．

elders enjoy extremely high living standard in Britain
