SummaryPopulations and ways of sustaining them are not in balance, and the trend is toward greater imbalance rather than equilibrium.Malthusian think the population is increasing in a geometrical rate ,while substance increases in a arithmetical rate.Nature will reestablish a balance between resources and population numbers.Malthus wrote from the standpoint of the propertied class.He had a low opinion of the “lower classes”, and his essay is full of expressions of disdain and opprobium toward the poor.Some of Malthus’s hypothesis is correct ,some are still remained teste.However, Ester Boserup argued that population determines agricultural methods, she think “necessity is the mother of invention”, humans would always find ways to support themselves.Allan have many ideas agree with Boserup, He devised a method of determining how many historical changes:stage1:high birth rate and high death rate,and low population growth.Stage2:high birth rate, low death rate, high population growth.stage3:low birth rate, flow death rate, low population growth.Japan has passed through the demographic transition.By 1966, many African countries were in stage1 of the demographic transition, A few were entering stage2.By 1993, many African countries finished stage1 ,and moved to stage2, only a few countries seemed to on the way to completing a transition or had essentially completed the demographic transition.The third stage of the demographic transition were occurring in many parts of the third world in 1993, but not in Africa.As the improvement of the technology and the economy can in turn carry the society through the demographic transition, so Commoner think the population problem lies in poverty, and its solution lies in the redistribution of wealth.In order to avoid a Malthusian Destiny, Harvey thinks the population-resource equation can be moved in the direction of equilibrium by changing any of four constituent parts of equation.In many less developed countries, a large family increase the amount of labor available for farming and the household economy.If one can guarantee the continuation of one’s family line and be secured in old age, the will limit the number of children one brings into the world.Many factors contribute to the achievement of the demographic transition, and literacy is worth further security.Literacy is one of civilization’s central tools, and the illiterate rate between man and women is different, the gab between man and women has increased narrowed somewhat.

专业英语大作业

一、翻译

1.The breadth and complexity of the environmental problems we face and the scientific, economic and social impediments to their solution emphasize how important it is that environmental scientists and engineers gain an appreciation for the processes and functioning of all environmental compartments — air, soil, water, and energy — and intentionally account for the long-term consequences and sustainability of the actions they propose, whether they be preventative or remedial.我们所面临的环境问题的广度和复杂程度以及对解决这个问题的科学的、经济的、社会的阻碍，都集中到了这样一个重要性：环境科学家与工程师们获得一个对多有环境因素诸如空气、石油、水、能量的流程和功能的判断，有意阐明所提议的行为的长期结果和可持续发展性，是否他们（环境问题）可以预防和补救。

2.As these next-generation technologies are considered, the selection of those for further development and implementation ought to consider a broadened definition of performance to include improved water quality and quantity as well as energy and materials consumption, ecosystem function at the source and sink, life-cycle impacts, and human-health outcomes.这些被认为是下一代技术,它们进一步开发和实现的选择应当考虑改善水质量和数量,以及能源和材料消耗, 在源和水槽,生命周期的影响、人类健康结果的影响的生态系统功能的定义。

3.The next step is to combine the exposure data with so-called exposure–response(or concentration–response)functions(the quantified relationship between health risk and exposure to air pollution)and data for the actual frequency in the given area of, for example, deaths and hospital admissions due to air-pollution-related diseases.考试过程中不得将试卷拆开

下一步是把曝光数据与所谓的曝光–反应（或浓度–响应）功能(健康风险和暴露于空气污染之间的量化关系)和数据的实际频率的特定区域（例如，死亡和因空气污染住院的）相结合

4.Environmental engineers must seek to understand the nature and functioning of large and complex systems in order to protect whole ecosystems, produce new and sustainable technologies, prevent the outbreak of diseases across global scales, and protect the environment from damage resulting from the production of new chemicals.环境工程师必须去理解性质和功能大而复杂的系统,以保护整个生态系统产生新的、可持续的技术,防止疾病的疫情在全球范围传播,保护环境免受新化学物质的破坏。

5.With increased scientific knowledge derived from laboratory studies and environmental monitoring concerning the impacts of the residual constituents found in secondary effluent, it is anticipated that many of the methods now classified as advanced will become conventional within the next 5 to 10 years.随着实验室研究和环境监测有关发现二级污水中残留成分的影响，科学知识在急剧增加，预计,有许多现在列为先进的技术将在未来5至10年成为传统的方法。

6.Nonselective in their mode of attack and able to operate at normal temperature and pressures, hydroxyl radicals are capable of oxidizing almost all reduced materials present without restriction to specific classes or groups of compounds, as compared to other oxidants.相比其他氧化剂，它们能够在非选择性的攻击模式、在正常的温度和压力下,减少几乎所有材料的羟基自由基的氧化能力，然而现在它们没有被划分到具体的类或化合物组，7.International development organizations and human rights groups increasingly insist, however, that environmental problems that deprive vulnerable populations in developing countries of access to shelter, water, or food or that spread diseases, whatever the sources, are security issues.虽然环境问题剥夺了发展中国家的弱势群体获得庇护的权利, 但是, 国际发展组织和人权考试过程中不得将试卷拆开

to humans, other species, or systems that need to be protected.出于公共利益,由政府拨款的鼓励基金支持研究人员用他们的研究来评估伤害或潜在伤害人类的“环境”, 需要保护的其他物种或系统，9.The North China Plain bounded by the Hai, Huai, and Yellow rivers has 33% of China’s population and generates the same national percentage of gross domestic product(GDP)and industrial output, yet only shares 7.7% of the national water resources.Conversely, 21.3% of the country’s water resources are in the southwest, but that region accounts for only 0.7% of the national GDP and industrial output.华北平原有东海,淮河和黄河，拥有中国33%的人口和相同比例的国内生产总值(GDP)和工业产出,但却只有7.7%的国家水资源。相反,我国21.3%的水资源在西南地区,但该地区仅占国家GDP和工业产值的0.7%。

10.The projection is based on a wide range of assumptions about the main forces driving future emissions(such as population growth and technological change)but does not reflect any efforts to control emissions due to concerns about climate change.这个投影是基于驱动未来的碳排放的主要因素(人口增长和技术变革等)一系列假设,但并不能反映由于人们对气候变化的担忧而控制排放的努力。

11.As developing nations industrialize, pollutant concentrations and the numbers of exposed individuals increase;as new chemicals are added to our environment we discover more complex and troubling impacts;as we more carefully monitor ecosystems, we become more alarmed at the threats our activities have on the very fabric of life on Earth.当发展中国家正在工业化时，污染物聚集程度以及暴露在这些化学品影响之下的人数都在考试过程中不得将试卷拆开

逐渐增加；当新的化学物质被应用到我们日常环境中时，我们发现了越来越多的复杂和麻烦的影响；当我们越来越细心仔细的监视着生态系统时，我们也变的对由我们自己日常活动给地球上基本生活结构带来的威胁越来越警觉。

12.Recognition of this interconnectedness has led the African Development Bank and other development organizations to agree that integrating adaptation responses into development planning, which includes improvements in water and sanitation, is an important way to address climate change impacts on the poor.识别的互联性导致了非洲开发银行和其他开发组织同意将适应反应集成到发展规划中,其中包括改善水和卫生设施这一个重要的方法来应对气候变化对穷人的影响

13.Research is ongoing to determine(1)the environmental effects of potential toxic and biologically active substances found in wastewater and(2)how these substances can be removed by both conventional and advanced wastewater-treatment processes.研究确定：(1)废水的环境具有潜在的毒性并可以对生物活性物质产生影响(2)如何利用传统和先进的污水处理工艺发现这些物质

14.For example, a qualitative test may involve the use of a reagent which develops a colour in the presence of the analyte.However, below a certain concentration or detection limit the colour will not be detectable.Thus, the qualitative test is quantitative also in the sense that it can only show that the analyte concentration does not exceed a certain detection limit.例如,定性试验可能涉及使用试剂开发分析物存在的色彩。然而,低于一定浓度或检测极限的颜色不会被检测到。因此,定性试验在某种意义上只能显示浓度不超过一定的检出限的分析物

15.Much of the environment damage caused by developments occurs during the construction phase, and a problem is that construction is usually contracted to a construction company who will not have participated in the EIA process, and over whom the developer may have little control.许多损害环境的事是发生在施工阶段,其中一个问题是,施工单位通常是一个不会参与环境考试过程中不得将试卷拆开
