    Section A – This ONE question is compulsory and MUST be attempted

    Hesket Nuclear (HN) is a nuclear power station in Ayland, a large European country. The HN plant is operated by Hesket Power Company (HPC), which in turn is wholly owned by the government of Ayland. Initially opened in the late 1950s, the power station grew in subsequent decades by the addition of several other facilities on the same site. HN now has the ability to generate 5% of Ayland’s entire electricity demand and is one of the largest nuclear stations in Europe. At each stage of its development from the 1950s to the present day, development on the site was welcomed by the relevant local government authorities, by the businesses that have supported it, by the trade union that represents the majority of employees (called Forward Together or FT for short) and also by the national Ayland government. A nuclear reprocessing facility was added in the 1980s. This is a valuable source of overseas income as nuclear power producers in many other parts of the world send material by sea to HN to be reprocessed. This includes nuclear producers in several developing countries that rely on the cheaper reprocessed fuel (compared to ‘virgin’ fuel) that HN produces.

    HPC is loss-making and receives a substantial subsidy each year from the government of Ayland. HPC has proven itself uneconomic but is deemed politically and environmentally necessary as far as the government is concerned. The government of Ayland has reluctantly accepted that large subsidies to HPC will be necessary for many years but considers nuclear power to be a vital component of its energy portfolio (along with other energy sources such as oil, gas, coal, renewables and hydroelectric) and also as a key part of its ‘clean’ energy strategy. Unlike energy from fossil fuels (such as coal, gas and oil), nuclear power generates a negligible amount of polluting greenhouse gas. HN also provides much needed employment in an otherwise deprived part of the country. The HN power station underpins and dominates the economy of its local area and local government authorities say that the HN plant is vital to the regional economy.

    Since it opened, however, the HN power station has been controversial. Whilst being welcomed by those who benefi t from it in terms of jobs, trade, reprocessing capacity and energy, a coalition has gradually built up against it comprising those sceptical about the safety and environmental impact of nuclear power. Some neighbouring countries believe themselves to be vulnerable to radioactive contamination from the HN plant. In particular, two countries, both of whom say their concerns about HN arise because of their geographical positions, are vocal opponents. They say that their geographical proximity forced them to be concerned as they are affected by the location of the HN plant which was not of their choosing.

    The government of Beeland, whose capital city is 70 km across the sea from HN (which is situated on the coast), has consistently opposed HN and has frequently asked the government of Ayland to close HN down. The Beeland government claims that not only does ‘low-level’ emission from the site already contaminate the waters separating the two countries but it also claims that any future major nuclear ‘incident’ would have serious implications for the citizens of Beeland. There is some scientifi c support for this view although opinion is divided over whether Beeland is being irrational in its general opposition to HN.

    The government of Ceeland is also a vocal opponent of HN. Ceeland is located to the north of Beeland and approximately 500 km away from Ayland. Some nuclear scientists have said that with such a large stretch of water between the HN plant and Ceeland, even a much-feared incident would be unlikely to seriously impact on Ceeland. Some commentators have gone further and said that Ceeland’s concerns are unfounded and ‘borne of ignorance’. FT, the trade union for HN employees, issued a statement saying that Ceeland had no reason to fear HN and that its fears were ‘entirely groundless’.

    HN’s other vocal and persistent opponent is No Nuclear Now (NNN), a well-organised and well-funded campaigning group. Describing itself on its website as ‘passionate about the environment’, it describes HN’s social and environmental footprint as ‘very negative’. NNN has often pointed to an environmentally important colony of rare seals living near the HN plant. It says that the seals are dependent on a local natural ecosystem around the plant and are unable to move, arguing that the animals are at signifi cant risk from low-level contamination and would have ‘no chance’ of survival if a more serious radioactive leak ever occurred. NNN points to such a leak that occurred in the 1970s, saying that such a leak proves that HN has a poor safety record and that a leak could easily recur.

    Each time an objection to the HN power station is raised, FT, the trade union, robustly defends the HN site in the media, and argues for further investment, based on the need to protect the jobs at the site. Furthermore, the radiation leak in the 1970s led to FT uniting with the HPC board to argue against those stakeholders that wanted to use the leak as a reason to close the HN site. The combination of union and HPC management was able to counter the arguments of those asking for closure.

    HN places a great deal of emphasis on its risk management and often publicises the fact that it conducts continual risk assessments and is in full compliance with all relevant regulatory frameworks. Similarly, FT recently pointed out that HN has had an ‘impeccable’ safety record since the incident in the 1970s and says on its website that it is ‘proud’ that its members are involved in ensuring that the company is continually in full compliance with all of the regulatory requirements placed upon it.

    The board of HPC, led by chairman Paul Gog, is under continual pressure from the government of Ayland to minimise the amount of government subsidy. Each year, the government places challenging targets on the HPC board requiring stringent cost controls at the HN power station. In seeking to reduce maintenance costs on the expiry of a prior maintenance contract last year, the board awarded the new contract to an overseas company that brought its own workers in from abroad rather than employing local people. The previous contract company was outraged to have lost the contract and the move also triggered an angry response from the local workforce and from FT, the representative trade union.

    FT said that it was deplorable that HPC had awarded the contract to an overseas company when a domestic company in Ayland could have been awarded the work. The union convenor, Kate Allujah, said that especially in the nuclear industry where safety was so important, domestic workers were ‘more reliable’ than foreign workers who were brought in purely on the basis of cost and in whose countries safety standards in similar industries might not be so stringent. HPC said that it had done nothing illegal as the foreign workers were allowed to work in Ayland under international legal treaties. Furthermore, it argued that pressure by FT to raise wages over recent years had created, with the government’s subsidy targets, the cost pressure to re-tender the maintenance contract.

    On HN’s 50th anniversary last year, NNN published what it called a ‘risk assessment’ for the HN power station. It said it had calculated the probabilities (P) and impacts (I) of three prominent risks.

    Risk of major radioactive leak over the next 10 years: P = 10%, I = 20

    Risk of nuclear explosion over the next 50 years: P = 20%, I = 100

    Risk of major terrorist attack over next 10 years: P = 10%, I = 80

    Impacts were on an arbitrary scale of 1–100 where 100 was defi ned by NNN as ‘total nuclear annihilation of the area and thousands of deaths’.

    The governments of Beeland and Ceeland seized upon the report, saying that it proved that HN is a genuine threat to their security and should be immediately closed and decommissioned. HN’s risk manager, Keith Wan, vigorously disagreed with this assessment saying that the probabilities and the impacts were ‘ridiculous’, massively overstated and intended to unnecessarily alarm people. HN’s public relations offi ce was also angry about it and said it would issue a rebuttal statement.

    正确答案:

    (a) Distinguish and identify
    Voluntary stakeholders are those that engage with an organisation of their own choice and free will. They are ultimately (in the long term) able to detach and discontinue their stakeholding if they choose. Involuntary stakeholders have their stakeholding imposed and are unable to detach or withdraw of their own volition.

    The voluntary stakeholders identifi ed in the case are: Forward Together (the trade union), Hesket Nuclear employees, the Ayland government, the board of HPC, local authorities, No Nuclear Now and other nuclear producers who use the reprocessing facility.

    The involuntary stakeholders – those whose stakeholding is placed upon them by virtue of their physical position – are the governments of Beeland and Ceeland, the local community and the seal colony.

    [Tutorial note: membership of these categories is contestable if time perspectives are introduced. In the short term, some voluntary stakeholders are involuntary in that their involvement cannot be quickly withdrawn. The case clearly identifi es the involuntary stakeholders.]

    Assess the claims
    The case identifi es three ‘affected’ stakeholders that are clearly involuntary. Both Beeland and Ceeland say that they are stakeholders because of their geographical position and the seals are unable to move because of local environmental conditions.

    Beeland government’s claim is based on its position near to the Hesket plant. With the capital 70 km from the plant, it claims that it is already the ‘victim’ of low level radiation in the sea between the two countries. The case does not give the radius of damage if a major incident were to occur but it does say that there is ‘scientifi c support’ for the view that it could affect the capital of Beeland. Assuming that both of these statements are accurate then the Beeland government would appear to have a legitimate and reasonable claim that they are affected by the Hesket Nuclear plant and could be further affected in the future.

    The government of Ceeland claims to be a potential ‘victim’ of nuclear contamination from the HN plant and has sought to have the plant closed as a result. The weakness of its claim rests upon the physical distance away from HN (500 km). If the threats to Ceeland are, as scientists have suggested, ‘unfounded and borne of ignorance’ then clearly Ceeland has a weak claim over Hesket Nuclear. It may have political reasons of its own to make protestations, perhaps to appease opinion in Ceeland or to be populist to manage dissent at home.

    The case says that the local seal colony is unable to move away from the HN plant because of the local environmental conditions there and so it is unable to discontinue its stakeholding. It is thus involuntary. Low level emissions could potentially affect the seals and their food sources and any major incident would obviously impact it signifi cantly. Whilst their affectedness is therefore indisputable, the value of the colony’s claim rests in part upon the value placed upon sea life value against human and economic value. This assessment is therefore contestable.

    The local community is another involuntary stakeholder albeit with a weaker involuntary element than the above three described. Whilst not structurally involuntary (they are able to move away if they do not like it), many local citizens may have lived near the HN plant for many years before it was built and may therefore have simply had to accept its development regardless of their views. The impacts on local communities can be positive or negative in that HN supports them through the provision of jobs but they would also be the fi rst and most affected if there ever was a major incident at the HN plant.

    [Tutorial note: allow for other ‘affected’ stakeholders if coherently argued. It is possible to argue that the taxpayers of Ayland are affected involuntary stakeholders, for example.]

    (b) Roles of employee representatives
    Trade unions are the most usual example of employee representation in corporate governance. Trade unions represent employees in a work facility such as an offi ce or a plant. Membership is voluntary and the infl uence of the union is usually proportional to its proportion of membership.

    Although a trade union is by default assumed to have an adversarial role with management, its ability to ‘deliver’ the compliance of a workforce can help signifi cantly in corporate governance. When an external threat is faced, such as with the reputation losses following the 1970s leak, then the coalition of workforce (via Forward Together) and management meant that it was more diffi cult for external critics to gain support.

    A trade union is an actor in the checks and balances of power within a corporate governance structure. Where management abuses occur, it is often the trade union that is the fi rst and most effective reaction against it and this can often work to the advantage of shareholders or other owners, especially when the abuse has the ability to affect productivity.

    Trade unions help to maintain and control one of the most valuable assets in an organisation (employees). Where a helpful and mutually constructive relationship is cultivated between union and employer then an optimally effi cient industrial relations climate exists, thus reinforcing the productivity of human resources in the organisation. In defending members’ interests and negotiating terms and conditions, the union helps to ensure that the workforce is content and able to work with maximum effi ciency and effectiveness.

    Critically evaluate the contribution of Forward Together from HPC’s perspective

    Helpful roles
    The case describes Forward Together’s (FT) role as generally supportive of the development of the Hesket Nuclear site. Clearly, with a primary loyalty to its members, FT will always pursue causes that are going to maximise members’ job security. When the primary external stakeholder pressure is for the reduction of the HN site, the union and board are aligned in their objectives for the continuation of the facility.

    FT’s statement over Ceeland’s concern was very helpful to the HPC board. FT has a clear interest in diffusing unfounded concern where it exists and its statement that Ceeland’s fears were ‘entirely groundless’ would reinforce the power of any similar such statement made by others. Similarly, FT provided support after the leakage incident in the 1970s. The helpful reinforcement was evident when FT pointed to the impeccable safety record and compliance. This may have meant more as a public relations exercise coming from the trade union rather than the HPC board as FT is independent of the company.

    Unhelpful roles
    FT’s wage pressure, over time, put a pressure on the company’s costs that had, according to the HPC board, created the need to bring in cheaper foreign workers to fulfi l the maintenance contract. From the board of HPC’s viewpoint, such pressure was ultimately self-defeating for the union and effectively meant that the previous maintenance contractor was priced out. The union had been short-sighted in its year-on-year wage demands.

    We are not told whether the board agrees with Kate Allujah that workers from Ayland were ‘more reliable’ in such a risk sensitive industry, but her comment was possibly based on prejudice against foreign workers entering the country. She seemed to be unconcerned with the legal implications of her outrage. Given that the company was legally entitled to employ foreign workers in Ayland, she had no valid legal argument for her position. From an economic perspective, it is also unhelpful, from HPC’s perspective to have the union making high wage demands and then complaining about legitimate measures that the company takes to stay within its government subsidy such as cutting costs, including labour costs.

    Conclusion
    HPC’s relationship with FT has been positive and mutually benefi cial for the majority of the company’s history. Clearly seeing their destinies to be linked, FT has supported the company against external threats but has, at the same time, used its good relations to make wage demands that ultimately led to the award of a maintenance contract to the foreign workers. This would have broken an important relationship with experienced maintenance personnel and the foreign workers may or may not have had the same level of expertise as the previous workers.

    (c) Explain agency relationship
    An agency relationship is one of trust between an agent and a principal which obliges the agent to meet the objectives placed upon it by the principal. As one appointed by a principal to manage, oversee or further the principal’s specifi c interests, the primary purpose of agency is to discharge its fi duciary duty to the principal. In this case, there is an agency relationship between the government and the board of HPC.

    Examine existing agency relationship
    Although HPC is run by a conventional board, the company is wholly owned by the government of Ayland. This means that the company’s strategic objectives are determined by the government and these are likely to be different from purely commercial concerns. The nuclear operation is clearly not economic in terms of profi t and so the government’s objectives for the company must be other than that. The case describes this in terms of broadening its energy portfolio and meeting environmental objectives. The board’s objectives are likely to be predominantly fi nancial, due to the control by subsidy placed upon it, but the principal’s political and environmental concerns may also affect the objectives placed upon the HPC board (such as employment objectives in what is a deprived region of Ayland).

    The principal is the government of Ayland and ultimately the board is accountable to the taxpayers of Ayland. This means that the development and even the existence of HN is ultimately under democratic control. The agency relationship means that the board of HPC has subsidy targets and also sees its role as fulfi lling an important role in Ayland’s energy portfolio.

    HPC as a ‘conventional’ company owned by private shareholders
    If HPC was a private company, its principals would be shareholders with very different objectives. Shareholders would be predominantly concerned with the economic performance of HP and the economies of the nuclear power industry. It would insist that the board pursued only those parts of the business that were profi table. This would necessitate a radical redesign of HPC’s business as we are told that in its present form. it is loss-making.

    (d) (i)

    Statement
    Hesket Power Company’s response to the report produced by NNN

    Importance of risk assessment at Hesket Power Company
    Hesket Power Company was recently dismayed to have been made aware of a report conducted by an anti-nuclear pressure group purporting to be a risk assessment of selected risks to the Hesket Nuclear plant. The company would like to take this opportunity to inform. the public about the irresponsibility of the pressure group’s activity whilst comprehensively rejecting its arguments.

    In all industries it is important to assess risks as accurately as possible but in the nuclear power industry, it is critical. It is because the pressure group misrepresented our risks that we feel it necessary to remind stakeholders about the importance of a correct risk assessment based on valid measurements.

    In observing best practice, Hesket Nuclear carries out thorough and continual risk assessments in compliance with our regulatory frameworks. The information going into the process must be as accurate as possible because resources are allocated in part on the basis of our risk assessments. Clearly, a risk assessed as probable and of high impact would attract a signifi cant resource allocation and to have incorrect information could conceivably lead to the misallocation of company resources. This, in turn, would be a failure of our duty to the HPC company and ultimately to our owners, the government of Ayland and its taxpayers. The fact that there has not been a serious incident since the 1970s highlights the efforts that we take with risk assessment.

    The ways in which we manage risk also depend upon the assessment. Once a risk, such as the risk of a nuclear leakage, is identifi ed and assessed, the company pursues a strategy for managing that risk, typically to transfer or share the risk, avoid the risk, reduce it or accept it. This has implications for the entire strategy of the organisation, especially where the assessed risks are strategic in nature. Inaccurate assessment might, for example, mean accepting a risk that should have been avoided or vice versa.

    Our stakeholders expect us to be a responsible company in all matters but especially in matters of safety and the environment. We owe it to our local community, employees and others to ensure that all risks are fully but accurately understood. In addition to ensuring that we are fully compliant with all regulatory regimes applicable to us, we believe that accurate risk assessment is necessary to our valued reputation as an ethical and responsible employer and neighbour.

    Finally, as we have seen in the case of this misguided report by the pressure group, inaccurate assessments can breed fear, distrust and unnecessary panic. HPC was disappointed to hear the report being used by critics when the information it contained was inaccurate and this leads us to the second matter.

    (ii) HN’s social and environmental ‘footprint’

    HPC is aware of some critics that have asserted that our overall footprint is negative. In responding to this, we feel it necessary to remind readers that the footprint of any organisation includes the sum total of its positive and negative interactions with the environment. Whilst this sometimes involves negative impacts such as carbon emissions and accidental pollution, it also takes into account the positive impacts such as social benefi t, through such things as job creation, and positive environmental impacts. Both ‘sides’ need to be taken into account before an overall evaluation of the social and environmental footprint can be established. To focus on only a small number of measures, as some of our critics have done, is to provide an unfair and biased account of our genuine overall footprint.

    Social arguments
    It is our belief that Hesket Nuclear makes a substantial positive contribution on both social and environmental measures. In terms of social contribution, HN makes a positive impact for several reasons. Whilst accepting that Hesket Nuclear has its critics, the company would like to remind the public both in Ayland and Beeland that the plant is a very large employer and vital to the economic well-being of the region, a fact recognised by a wide range of local and national stakeholders. Others have noted the importance of the jobs provided at Hesket Nuclear to the social and economic well-being of the region and HPC fully agrees with this analysis.

    In addition to the jobs provided in Ayland, Hesket Nuclear also provides reprocessed fuel that is cheaper than virgin fuel. This provides support for nuclear power, and hence clean energy, in several developing countries that are our valued customers. Hesket Nuclear therefore indirectly supports employment and social development in those countries. Were our reprocessed fuel unavailable to them, rates of economic and social development growth may be slowed in those countries. We are therefore determined to continue to supply this vital input into those countries and to continue to support them.

    Environmental arguments
    In addition, as a non-fossil fuel industry, nuclear is relatively non-polluting and is an essential component of the government of Ayland’s clean energy strategy. Hesket Nuclear is proud to be a part of that strategy and will continue to be a dependable producer of nuclear power and reprocessing services. In so doing we will continue to carefully manage the risks of nuclear power supply whilst providing the jobs and clean energy for which Hesket Nuclear is corporately responsible. A likely alternative to nuclear is the burning of more polluting fossil fuels which would presumably be as unacceptable to our critics as it is to us.

    Whilst conceding that all nuclear operations require a high level of safety and regulatory observance, we are pleased to be able to remind our stakeholders, including the governments of Beeland and Ceeland, of our very high performance in this area. As our colleagues in the Forward Together trade union recently said, Hesket Nuclear has had an impeccable safety record since the 1970s and is fully compliant with all relevant safety regulations. We fully intend to maintain this high level of performance.

    Text 2 A deal is a deal-except,apparently,when Entergy is involved.The company,a major energy supplier in New England,provoked justified outrage in Vermont last week when it announced it was reneging on a longstanding commitment to abide by the strict nuclear regulations.Instead,the company has done precisely what it had long promised it would not challenge the constitutionality of Vermont’s rules in the federal court,as part of a desperate effort to keep its Vermont Yankee nuclear power plant running.It’s a stunning move.The conflict has been surfacing since 2002,when the corporation bought Vermont’s only nuclear power plant,an aging reactor in Vernon.As a condition of receiving state approval for the sale,the company agreed to seek permission from state regulators to operate past 2012.In 2006,the state went a step further,requiring that any extension of the plant’s license be subject to Vermont legislature’s approval.Then,too,the company went along.Either Entergy never really intended to live by those commitments,or it simply didn’t foresee what would happen next.A string of accidents,including the partial collapse of a cooling tower in 207 and the discovery of an underground pipe system leakage,raised serious questions about both Vermont Yankee’s safety and Entergy’s management–especially after the company made misleading statements about the pipe.Enraged by Entergy’s behavior,the Vermont Senate voted 26 to 4 last year against allowing an extension.Now the company is suddenly claiming that the 2002 agreement is invalid because of the 2006 legislation,and that only the federal government has regulatory power over nuclear issues.The legal issues in the case are obscure:whereas the Supreme Court has ruled that states do have some regulatory authority over nuclear power,legal scholars say that Vermont case will offer a precedent-setting test of how far those powers extend.Certainly,there are valid concerns about the patchwork regulations that could result if every state sets its own rules.But had Entergy kept its word,that debate would be beside the point.The company seems to have concluded that its reputation in Vermont is already so damaged that it has noting left to lose by going to war with the state.But there should be consequences.Permission to run a nuclear plant is a poblic trust.Entergy runs 11 other reactors in the United States,including Pilgrim Nuclear station in Plymouth.Pledging to run Pilgrim safely,the company has applied for federal permission to keep it open for another 20 years.But as the Nuclear Regulatory Commission(NRC)reviews the company’s application,it should keep it mind what promises from Entergy are worth.27.By entering into the 2002 agreement,Entergy intended to

    A.obtain protection from Vermont regulators.
    B.seek favor from the federal legislature.
    C.acquire an extension of its business license.
    D.get permission to purchase a power plant.

    Nuclear Power and Its Danger

    Nuclear power's danger to health,safety,and even life itself can be summed up in one word:radiation.
    Nuclear radiation has a certain mystery about it,partly because it cannot be detected by human senses.It can't be seen or heard,or touched or tasted,even though it may be all around us.There are other things like that. For example,radio waves are all around us but we can't detect them,sense them,without a radio receiver. Similarly,we can't sense radioactivity without a radiation detector. But unlike common radio waves,nuclear radiation is not harmless to human beings and other living things.
    At very high levels,radiation can kill an animal or human being outright by killing masses of cells in vital organs.But even the lowest level of radiation can do serious damage.There is no level of radiation that is completely safe.If the radiation does not hit anything important,the damage may not be significant. This is the case when only a few cells are hit,and if they are killed outright,your body will replace the dead cells with healthy ones.But if the few cells are only damaged,and if they reproduce themselves,you may be in trouble.They reproduce themselves in a deformed way.They can grow into cancer. Sometimes this does not show up for many years.
    This is another reason for some of the mystery about nuclear radiation.Serious damage can be done without the victim being aware at the time that damage has occurred.A person can be irradiated and feel fine,then die of cancer five,ten,or twenty years later as a result.Or a child can be born weak or liable to serious illness as result of radiation absorbed by its grandparents.
    Radiation can hurt us.We must know the truth.

    According to the passage,the danger of nuclear power lies in________.
    A:nuclear mystery
    B:radiation detection
    C:nuclear radiation
    D:radiation level

    答案:C
    解析:

    核辐射会给我们选项A、B和C几个方面的损害,只有D概括较全面,所以D正确。

    The Family
    The structure of a family takes different forms around the world and even in the same society.
    The family's form changes as it adapts to changing social and economic influences.Until recently, the most common form in North America was the nuclear family,consisting of a married couple with their minor children.The nuclear family is an independent unit.It must be prepared to fend for itself. Individual family members strongly depend on one another. There is little help from outside the family in emergencies.Elderly relatives of a nuclear family are cared for only if it is possible for the family to do so.In North America,the elderly often do not live with the family;they live in retirement communities and nursing homes.
    There are many parallels between the nuclear family in industrial societies,such as North
    America,and of families in societies such as that of the Inuits,who live in harsh environments.
    The nuclear family structure is well adapted to a life of mobility. In harsh conditions,mobility allows the family to hunt for food.For North Americans,the hunt for jobs and improved social status also requires mobility.
    The nuclear family was not always the North American standard.In a more agrarian time,the small nuclear family was usually part of a larger extended family.This might have included grandparents,mother and father,brothers and sisters,uncles,aunts,and cousins.In North America today,there is a dramatic rise in the number of single-parent households.Twice as many households in the United States are headed by divorced, separated,or never-married individuals as are comprised of nuclear families. The structure of the family,not just in North America,but throughout the world,continues to change as it adapts to changing conditions.

    According to the passage,which is the definition of a nuclear family?
    A:.A nuclear family is a married couple with their minor children.
    B: A nuclear family is a single father with minor children.
    C: A nuclear family concludes parents,grandparents,and children.
    D: A nuclear family concludes parents,children,and aunts and uncles.

    答案:A
    解析:
    主旨题。题干意为“下面哪个选项可以作为这篇短文另一个合适的标题?”。短文开篇就提到了家庭结构,短文最后一句意为“不仅在北美洲,在全世界范围,家庭结构都会随着情况的不断变化而改变。”由此可见这篇短文的主题与家庭结构相关,由此可以进一步确认答案为A“家庭的结构是什么”。


    细节题。题干意为“根据文章,哪个是核心家庭的定义?”。第一段的第三句话对于核心家庭进行了定义Until recently , the most common form in North American was the nu-clear family , consisting of a married couple with their minor children.该句意为“直到最近,北美洲最普遍的家庭形式为核心家庭,由一对夫妇和他们未成年的孩子构成”。由此可知A“核心家庭是由一对夫妇和他们未成年的孩子构成的家庭”是答案。


    主旨题。题干意为“这篇文章最有可能出自哪里?”。该短文主题涉及家庭,因此最有可能出自人类学课本,所以A是正确的答案。


    题干意为“第一段主要以何种方式陈述的?”根据第一段的陈述方式,并没有列出数据或者讲故事,而是通过描述共性而阐述出核心家庭的概念。因此C“指出相似性”是正确的答案。


    题干意为“mobility是什么意思?”mobility是mobile“可移动的,机动的”的名词形式。首先在短文中找到mobility存在的语境:第二段中“The nuclear family structure is well adapted to a life of mobility…the hunt for jobs and improved social status also re-quires mobility. ”mobility所在的上下文意为“核心家庭结构良好地适应于……的生活。在恶劣的条件下,……能让一个家庭吃饱饭,时北美洲人来说,找工作和提高社会地位同样需要……”四个选项中,A意为“钱”,B意为“随时准备迁居”,C意为“组织,机构”,D意为“技能,技巧”,显然B“随时准备迁居”填入mobility所在的语境中合适,因此答案为B。

    Text 2 A deal is a deal-except,apparently,when Entergy is involved.The company,a major energy supplier in New England,provoked justified outrage in Vermont last week when it announced it was reneging on a longstanding commitment to abide by the strict nuclear regulations.Instead,the company has done precisely what it had long promised it would not challenge the constitutionality of Vermont’s rules in the federal court,as part of a desperate effort to keep its Vermont Yankee nuclear power plant running.It’s a stunning move.The conflict has been surfacing since 2002,when the corporation bought Vermont’s only nuclear power plant,an aging reactor in Vernon.As a condition of receiving state approval for the sale,the company agreed to seek permission from state regulators to operate past 2012.In 2006,the state went a step further,requiring that any extension of the plant’s license be subject to Vermont legislature’s approval.Then,too,the company went along.Either Entergy never really intended to live by those commitments,or it simply didn’t foresee what would happen next.A string of accidents,including the partial collapse of a cooling tower in 207 and the discovery of an underground pipe system leakage,raised serious questions about both Vermont Yankee’s safety and Entergy’s management–especially after the company made misleading statements about the pipe.Enraged by Entergy’s behavior,the Vermont Senate voted 26 to 4 last year against allowing an extension.Now the company is suddenly claiming that the 2002 agreement is invalid because of the 2006 legislation,and that only the federal government has regulatory power over nuclear issues.The legal issues in the case are obscure:whereas the Supreme Court has ruled that states do have some regulatory authority over nuclear power,legal scholars say that Vermont case will offer a precedent-setting test of how far those powers extend.Certainly,there are valid concerns about the patchwork regulations that could result if every state sets its own rules.But had Entergy kept its word,that debate would be beside the point.The company seems to have concluded that its reputation in Vermont is already so damaged that it has noting left to lose by going to war with the state.But there should be consequences.Permission to run a nuclear plant is a poblic trust.Entergy runs 11 other reactors in the United States,including Pilgrim Nuclear station in Plymouth.Pledging to run Pilgrim safely,the company has applied for federal permission to keep it open for another 20 years.But as the Nuclear Regulatory Commission(NRC)reviews the company’s application,it should keep it mind what promises from Entergy are worth.30.It can be inferred from the last paragraph that

    Nuclear Power and Its Danger

    Nuclear power's danger to health,safety,and even life itself can be summed up in one word:radiation.
    Nuclear radiation has a certain mystery about it,partly because it cannot be detected by human senses.
    It can't be seen or heard,or touched,or tasted,even though it may be all around us.There are other things
    like that.For example,radio waves are all around us but we can't detect them,sense them,without a radio
    receiver.Similarly,we can't sense radioactivity without a radiation detector. But unlike common radio waves,
    nuclear radiation is not harmless to'human beings and other living things.
    At very high levels,radiation can kill an animal or human being outright by killing masses of cells in
    vital organs.But even the lowest level of radiation can do serious damage.There is no level of radiation that is
    comnpletely safe.If the radiation does not hit anything important,the damage may not be significant.This is
    the case when only a few cells are hit,and if they are killed outright.Your body will replace the dead cells
    with healthy ones.But if the few cells are only damaged,and if they reproduce themselves,you may be in
    trouble.They reproduce themselves in a deformed way.They can grow into cancer. Sometimes this does not
    show up for many years.
    There is another reason for the mystery of nuclear radiation.Serious damage can be done without the
    victim being aware at the time that damage occurs. A person can be irradiated and feel fine,then die of cancer
    five,ten,or twenty years later as a result.Or a child can be born weak or liable to serious illness as a result
    of radiation absorbed by its grandparents.
    Radiation can hurt us.We must know the truth.

    According to the passage,the danger of nuclear power lise in_______________.
    A:nuclear mystery
    B:radiation detection
    C:nuclear radiation
    D:radiation level

    答案:C
    解析:
    由第一段内容可知核能的危险在于其辐射性。
    由第三段的第二句和该段最后四句可知,即使很少的细胞遭核辐射损坏(未被完全杀 死),也会造成严重的后果。
    该词是对本句中if条件句所述情况所造成的损害的评述,而其后两句是对该句的补充 说明,由这两句所述的“……你的身体会用健康的细胞取代坏死的细胞”可知,情况并不严重, 故选A。 fatal意为“致命的,灾难性的”,significant意为“重大的,影响深远的”。
    由第三段第一句、第三段最后四句和第四段最后一句可知,D项为正确答案。
    文章叙述了核辐射危害的严重性、潜伏性和长期性,由此可知,再怎么强调防辐射都不 为过。 第三篇 本文主要介绍了一种预侧山体滑坡的设备。

  • 第16题:

    nuclear localization signal, NLS (核定位信号)


    正确答案:是另一种形式的信号肽,可位于多肽序列的任何部分。一般含有4~8个氨基酸,且没有专一性,作用是帮助亲核蛋白进入细胞核。入核信号与导肽的区别在于:
    ①由含水的核孔通道来鉴别;
    ②入核信号是蛋白质的永久性部分,在引导入核过程中,并不被切除,可以反复使用,有利于细胞分裂后核蛋白重新入核。有多种类型的核定位信号,这些信号都具有一个带正电荷的肽核心。
