The lesson from dams is that big is not always beautiful. It doesn't help that building a big, powerful dam has become a symbol of achievement for nations and people striving to assert themselves. Egypt's leadership in the Arab world was cemented by the Aswan High Dam. Turkey's bid for First World status includes the giant Ataturk Dam.
But big dams tend not to work as intended. The Aswan Dam, for example, stopped the Nile flooding but deprived Egypt of the fertile silt that floods left—all in return for a giant reservoir of disease which is now so full of silt that it barely generates electricity.
And yet, the myth of controlling the waters persists. This week, in the heart of civilized Europe, Slovaks and Hungarians stopped just short of sending in the stoops in their contention over a dam on the Danube. The huge complex will probably have all the usual problems of big dams. But Slovakia is bidding for independence from the Gzechs, and now needs a dam to prove itself.
Meanwhile, in India, the World Bank has given the go-ahead to the even more wrong-headed Narmada Dam. And the bank has done this even though its advisors say the dam will cause hardship for the powerless and environmental destruction. The benefits are for the powerful, but they are far from guaranteed.
Proper, scientific study of the impacts of dams and of the cost and benefits of controlling water can help to resolve these conflicts, Hydroelectric power and flood control and irrigation are possible without building monster dams. But when you are dealing with myths, it is hard to be either proper, or scientific. It is time that the world learned the lessons of Aswan. You don't need a dam to be saved.

Rivers are one of our most important natural resources (资源). Many of the world&39;s great cities are located(坐落) on rivers, and almost every country has at least one river running through it that plays an important role in the lives of its people.
Since the beginning of the history, people have used rivers for transportation(运输). The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Gangs is great, but it is also important for transportation; Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation (航海), however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides transportation, rivers give food, water to drink, water for crops(庄稼), and chances for fun and entertainment for the people who live along their banks. In order to increase(增加) the supply of crops, engineers sometimes build a dam (大坝) across a river and let a lake from behind the dam. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals(化学物质) and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits (利益) of this natural resource.
The greatest river for navigation is ___________.
A.the Amazon
B.the Nile
C.the Mekong
D.the Mississippi
From a dam, people can use the water for ___________.A.keeping the rivers clean
B.only making electricity
C.washing clothes
D.irrigation and making electricity
The water in the river is polluted because of _____________.A.people's drinking water too much
B.people's swimming in the river too much
C.chemicals and other materials
D.people's building a dam across a river
The best title of the passage is ___________.A.Rivers in Cities
B.The importance of Rivers
C.Transportation
D.Natural Resources

principal (lead) contractor to build the Giant Dam Project in an East Asian country. The board of R&M prided itself in
observing the highest standards of corporate governance. R&M’s client, the government of the East Asian country, had
taken into account several factors in appointing the principal contractor including each bidder’s track record in large
civil engineering projects, the value of the bid and a statement, required from each bidder, on how it would deal with
the ‘sensitive issues’ and publicity that might arise as a result of the project.
The Giant Dam Project was seen as vital to the East Asian country’s economic development as it would provide a
large amount of hydroelectric power. This was seen as a ‘clean energy’ driver of future economic growth. The
government was keen to point out that because hydroelectric power did not involve the burning of fossil fuels, the
power would be environmentally clean and would contribute to the East Asian country’s ability to meet its
internationally agreed carbon emission targets. This, in turn, would contribute to the reduction of greenhouse gases
in the environment. Critics, such as the environmental pressure group ‘Stop-the-dam’, however, argued that the
project was far too large and the cost to the local environment would be unacceptable. Stop-the-dam was highly
organised and, according to press reports in Europe, was capable of disrupting progress on the dam by measures such
as creating ‘human barriers’ to the site and hiding people in tunnels who would have to be physically removed before
proceeding. A spokesman for Stop-the-dam said it would definitely be attempting to resist the Giant Dam Project when
construction started.
The project was intended to dam one of the region’s largest rivers, thus creating a massive lake behind it. The lake
would, the critics claimed, not only displace an estimated 100,000 people from their homes, but would also flood
productive farmland and destroy several rare plant and animal habitats. A number of important archaeological sites
would also be lost. The largest community to be relocated was the indigenous First Nation people who had lived on
and farmed the land for an estimated thousand years. A spokesman for the First Nation community said that the ‘true
price’ of hydroelectric power was ‘misery and cruelty’. A press report said that whilst the First Nation would be unlikely
to disrupt the building of the dam, it was highly likely that they would protest and also attempt to mobilise opinion in
other parts of the world against the Giant Dam Project.
The board of R&M was fully aware of the controversy when it submitted its tender to build the dam. The finance
director, Sally Grignard, had insisted on putting an amount into the tender for the management of ‘local risks’. Sally
was also responsible for the financing of the project for R&M. Although the client was expected to release money in
several ‘interim payments’ as the various parts of the project were completed to strict time deadlines, she anticipated
a number of working capital challenges for R&M, especially near the beginning where a number of early stage costs
would need to be incurred. There would, she explained, also be financing issues in managing the cash flows to R&M’s
many subcontractors. Although the major banks financed the client through a lending syndicate, R&M’s usual bank
said it was wary of lending directly to R&M for the Giant Dam Project because of the potential negative publicity that
might result. Another bank said it would provide R&M with its early stage working capital needs on the understanding
that its involvement in financing R&M to undertake the Giant Dam Project was not disclosed. A press statement from
Stop-the-dam said that it would do all it could to discover R&M’s financial lenders and publicly expose them. Sally
told the R&M board that some debt financing would be essential until the first interim payments from the client
became available.
When it was announced that R&M had won the contract to build the Giant Dam Project, some of its institutional
shareholders contacted Richard Markovnikoff, the chairman. They wanted reassurance that the company had fully
taken the environmental issues and other risks into account. One fund manager asked if Mr Markovnikoff could
explain the sustainability implications of the project to assess whether R&M shares were still suitable for his
environmentally sensitive clients. Mr Markovnikoff said, through the company’s investor relations department, that he
intended to give a statement at the next annual general meeting (AGM) that he hoped would address these
environmental concerns. He would also, he said, make a statement on the importance of confidentiality in the
financing of the early stage working capital needs.
(a) Any large project such as the Giant Dam Project has a number of stakeholders.
Required:
(i) Define the terms ‘stakeholder’ and ‘stakeholder claim’, and identify from the case FOUR of R&M’s
external stakeholders as it carries out the Giant Dam Project; (6 marks)
Renewable Energy Sources
Today petroleum (石油)provides around 40% of the world's energy needs, mostly fuelling automobiles. Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but it is the least efficient, unhealthiest and most environmentally damaging fossil fuel (矿物燃料). Natural gas reserves could fill some of the gap from oil, but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. Less-polluting renewable energy sources offer a more practical long-term energy solution. "Renewable" refers to the fact that these resources are not used faster than they can be replaced.
Hydroelectric (水力发电的)power is now the most common form. of renewable energy, supplying around 20% of world electricity. China's Three Gorges Dam is the largest ever. At five times the size of the US's Hoover Dam, its 26 turbines (涡轮机)will generate the equivalent energy of 18 coal-fired power stations. It will satisfy 3% of China's entire electricity demand.
In 2003, the first commercial power station to use tidal (潮汐的)currents in the open sea opened in Norway. It is designed like windmill (风车), but others take the form. of turbines.
As prices fall, wind power has become the fastest growing type of electricity generation-quadrupling (翻两番)worldwide between 1999 and 2005. Modern wind farms consist of turbines that generate electricity. Though it will be more expensive, there is more than enough wind to provide the world's entire energy needs. Wind farms come in onshore and offshore forms. They can often end up at spots of natural beauty, and are often unpopular with residents. And turbines are not totally harmless-they can interfere with radar, alter climate and kill sea birds. Scotland is building Europe's largest wind farm, which will power 200, 000 homes. The UK's goal is to generate one-fifth of power from renewable sources, mainly wind, by 2020. But this may cause problems, because wind is unreliable.
According to the passage, which of the following is the most polluting energy resource？
A．Petroleum.
B．Coal.
C．Natural gas
D．Water.
