Ltd, manufacturing a range of concrete based products used in making roads, pavements and walkways. The

production technology is very low tech and uses simple wooden moulds into which the concrete is poured. As a

consequence he is able to use low skilled and low cost labour, which would find it difficult to find alternative

employment in a region with high unemployment levels. The company has employed many of its workforce since its

creation in 1996. The company’s products are heavy, bulky and costly to transport. This means its market is limited

to a 30-mile area around the small rural town where the manufacturing facility is located. Its customers are a mix of

private sector building firms and public sector local councils responsible for maintaining roads and pavements. By its

nature much of the demand is seasonal and very price sensitive.

A large international civil engineering company has recently approached Clyde with an opportunity to become a

supplier of concrete blocks used in a sophisticated system for preventing coast and riverbank erosion. The process

involves interlocking blocks being placed on a durable textile base. Recent trends in global warming and pressure in

many countries to build in areas liable to flooding have created a growing international market for the patented erosion

prevention system. Clyde has the opportunity to become the sole UK supplier of the blocks and to be one of a small

number of suppliers able to export the blocks to Europe. To do it he will need to invest a significant amount in CAM

(computer aided manufacturing) technology with a linked investment in the workforce skills needed to operate the

new technology. The net result will be a small increase in the size of the labour force but redundancy for a significant

number of its existing workers either unwilling or unable to adapt to the demands of the new technology. Successful

entry into this new market will reduce his reliance on the seasonal low margin concrete products he currently produces

and significantly improve profitability.

One further complication exists. Concrete Solutions is located in a quiet residential area of its home town. Clyde is

under constant pressure from the local residents and their council representatives to reduce the amount of noise and

dust created in the production process. Any move into making the new blocks will increase the pollution problems

the residents face. There is a possibility of moving the whole manufacturing process to a site on a new industrial estate

being built by the council in a rival town. However closure of the existing site would lead to a loss of jobs in the current

location. Clyde has asked for your help in resolving his dilemma.

Required:

(a) Using models where appropriate, advise Clyde on whether he should choose to take advantage of the

opportunity offered by the international company. (12 marks)

shot at fabulous wealth—intentionally—in 1990. That's when he decided not to patent the technology used to create the most important software innovation in the final decade of the 20th century: the World Wide Web. Berners-Lee wanted to make the world a richer place, not amass personal wealth. So he gave his brainchild to us all.

Berners-Lee regards today's Web as a rebellious adolescent that can never fulfill his original expectations. By 2005, he hopes to begin replacing it with the Semantic Web—a smart network that will finally understand human languages and make computers virtually as easy to work with as other humans.

As envisioned by Berners-Lee, the new Web would understand not only the meaning of words and concepts but also theological relationships among them. That has awesome potential. Most knowledge is built on two pillars: semantic and mathematics. In number-crunching, computers already outclass people. Machines that are equally admit at dealing with language and reason won't just help people uncover new insights; they could blaze new trails on their own.

Even with a fairly crude version of this future Web, mining online repositories for nuggets of knowledge would no longer force people to wade through screen after screen of extraneous data. Instead, computers would dispatch intelligent agents, or software messengers, to explore Websites by the thousands and logically sift out just what's relevant. That alone would provide a major boost in productivity at work and at home. But there's far more.

Software agents could also take on many routine business chores, such as helping manufacturers find and negotiate with lowest-cost parts suppliers and handling help-desk questions. The Semantic Web would also be a bottomless trove of eureka insights. Most inventions and scientific breakthroughs, including today's Web, spring from novel combinations of existing knowledge. The Semantic Web would make it possible to evaluate more combinations overnight than a person could juggle in a lifetime. Sure scientists and other people can post ideas on the Web today for others to read. But with machines doing the reading and translating technical terms, related ideas from millions of Web pages could be distilled and summarized. That will lift the ability to assess and integrate information to new heights. The Semantic Web, Berners-Lee predicts, "will help more people become more intuitive as well as more analytical. It will foster global collaborations among people with diverse cultural perspectives, so we have a better chance of finding the right solutions to the really big issues—like the environment and climate warming".

Had he liked, Berners-Lee could have

A．created the most important innovation in the 1990s.

B．accumulated as much personal wealth as Bill Gates.

C．patented the technology of Microsoft software

D．given his brainchild to us all.

Passage One

Mark went to the neighborhood meeting after work. The area's city councilwoman (女议员) was leading a discussion about how the quality of life was decreasing. The neighborhood faced many problems. People were supposed to suggest solutions to the councilwoman. It was too much for Mark. "The problems are too big," he thought. He turned to the man next to him and said, "I think this is a waste of my time. Nothing I could do would make a difference here."

On his way back, Mark saw a woman carrying a grocery hag and baby. She was trying to unlock her car, but she didn't have a free hand. As Mark got closer, her other child, a little boy, suddenly darted into the street. The woman tried to reach for him, but as she moved, her bag shifted and groceries started to fall out. Mark ran to take the boy's arm and led him back to his mother. Then he picked up the groceries while the woman smiled in relief. "Thanks!" she said. "You've got great timing (适时) !"

"Just being neighborly (友好的) ," Mark said. As he rode home, he glanced at the walls of the bus passed by. On one of them was "Small acts of kindness add up." Mark smiled and thought, "Maybe that's a good place to start."

31. In the first paragraph, Mark thought that______.

A. nobody was so able as to solve these problems

B. many people were too selfish to think about others

C. he was not in the position to solve such problems

D. he already had more than enough work to do

t how to squeeze vast numbers of additional people into urban areas that are already extremely crowded. London, for example, will somehow have to deal with a projected 100,000 extra inhabitants every year until 2016. The current plan of building a new “satellite towns” of the city causes a lot of problems---but architecture think tanks are working on ambitious solutions that go vertical instead of horizontal in search of space.

In terms of population density, London is one of the least crowded major cities in the world---four times fewer people per square kilometer than Paris, for example, six times fewer than New York and eight times fewer than Cairo. But the fact remains that the city’s population is growing at a rapid rate, and horizontal expansion into the surrounding areas is eating up increasingly important agricultural land, as well as worsening all the transport problems that come with urban growth.

Popular Architecture would propose a radically different solution. The proposal is to go upwards, with vertical towers of considerable size, each representing an entire new town, by the time it’s completed. Each tower would be 1500 meters high. Beyond mere accommodation, each tower would function as an entire town unit, with its own schools, hospitals, parks and gardens, sports faculties, business areas and community spaces. The population density of such a tower could help lower the individual energy requirements of each inhabitant, reducing the ecological impact of the population as a whole.

The village towers are considered as hollow tubes, with large holes to allow light and air though the entire construction. Occasional floor discs spread throughout the height of the building will give inhabitants large central areas in the middle of the tube to use as gathering spaces.

While the building itself is unlikely ever to be seriously considered for construction---imagine the number of elevators it would need, let alone the safety implications of open areas at such heights and with such wind exposure---the concept can serve as conversation-starter for urban planners looking to face the challenges of the current and coming countries.

One key challenging task for urban architects in the future is to ______.

A.build new satellite towns

B.work out ambitious plans

C.design less crowded cities

D.accommodate more inhabitants

Which of the following cities has the largest population density？

A.Cairo.

B.Paris.

C.London.

D.New York.

Horizontal expansion not only wastes land, but makes it hard for London to ______.

A.handle its safety problems

B.resolve its transport issues

C.control its population growth

D.measure its population density

The vertical tower would represent an entire new town in itself because______.

A.it is energy-saving

B.it is cost-effective

C.it is self-sufficient

D.it is comfort-oriented

For city planners today, the idea of building a vertical tower can become______.A.a topic for fun

B.a shocking reality

C.a modest proposal

D.a source of inspiration

war is. There are shooting wars—the kind that test patriotism and courage—and those are the kind at which the U.S. excels. But other struggles test those qualities too. What else was the Great Depression or the space race or the construction of the railroads？ If Americans indulge in a bit of flag-waving when the job is done, they earned it.

Now there is a similar challenge: global warming. The steady deterioration (恶化) of the very climate of this very planet is becoming a war of the first order, and by any measure, the U.S. is losing. Indeed, if America is fighting at all, it's fighting on the wrong side. The U.S. produces nearly a quarter of the world's greenhouse gases each year and has stubbornly made it clear that it doesn't intend to do a whole lot about it. Although 174 nations approved the admittedly flawed Kyoto accords to reduce carbon levels, the U.S. walked away from them. There are vague promises of manufacturing fuel from herbs or powering cars with hydrogen. But for a country that tightly cites patriotism as one of its core values, the U.S. is taking a pass on what might be the most patriotic struggle of all. It's hard to imagine a bigger fight than one for the survival of a country's coasts and farms, the health of its people and the stability of its economy.

The rub is, if the vast majority of people increasingly agree that climate change is a global emergency, there's far less agreement on how to fix it. Industry offers its plans, which too often would fix little. Environmentalists offer theirs, which too often amount to na; ve wish lists that could weaken America's growth. But let's assume that those interested parties and others will always be at the table and will always demand that their voices be heard and that their needs be addressed. What would an aggressive, ambitious, effective plan look like—one that would leave the U.S. both environmentally safe and economically sound？

Halting climate change will be far harder. One of the more conservative plans for addressing the problem calls for a reduction of 25 billion tons of carbon emissions over the next 52 years. And yet by devising a consistent strategy that mixes short-term solutions with far-sighted goals, combines government activism with private-sector enterprise and blends pragmatism (实用主义) with ambition, the U.S. can, without major damage to the economy, help halt the worst effects of climate change and ensure the survival of its way of life for future generations. Money will do some of the work, but what's needed most is will. "I'm not saying the challenge isn't almost overwhelming," says Fred Krupp. "But this is America, and America has risen to these challenges before."

What does the passage mainly discuss？

A．Human wars.

B．Economic crisis.

C．America's environmental policies.

D．Global environment in general.
