• The phrase “personal space” has an odd touch that was characteristic of the 1970s. • In hot summer days people can be drawn to each other, especially to the opposite sex (or feel disgusted with the closeness of others.) • People in different regions have different sizes of personal space. • It is quite common that one person occupies a booth and a set of facing seats designed for four people. • The author hopes that his own stand against the shrinking of personal space, while small in itself, will nonetheless eventually have a dramatic effect in the same way as the breeze from a butterfly’s wings in Japan, if it initiates a chain of waves, may eventually produce a tidal wave in California.
• The pigeon was wedged in the fork of a branch and it fell after a while. • The payment that the motorist will have to make is proportional to the amount of damage he has done to the other person’s car. • You can only enter the cave by inching through a narrow tunnel on your stomach. • She stammered some apologies for entering my office without knocking as she sidled towards tto explain to me that I was dismissed not because I didn’t do my work well but because the company was confronted by financial troubles. • The enlistment of young soldiers infused new hope and morale into the army. • once the older boys stake a claim to the lawn, the younger ones had to give way to them to avoid conflict. • The man following her made her uneasy and she couldn’t help quickening her steps.

Unit 2 EconomicsI Teaching ObjectivesAfter learning Unit 2, students (Ss) are expected to develop the following academic skills and knowledge:II Teaching Activities and ResourcesReadingText ALead-inTeaching StepsAsk Ss to work in pairs and do the task in Lead-in. Then invite several Ss to share their answers with the whole class.Answer Keys1.The invisible hand.2.Our economic life is made possible by the skill and labor of vast numbers of totalstrangers.The activities of countless far-flung men and women have to be intricately choreographed and precisely timed. However, no one coordinates it, and yet they do cooperate. It’s “the invisible hand” —the mysterious power that leads innumerable people, each working for his own gain, to promote ends that benefit many. Out of the seeming chaos of millions of uncoordinated private transactions emerges the spontaneousText AnalysisTeaching Steps1.OverviewAsk Ss to preview Text A before class. Or, allocate some time for Ss to read the text quickly in class. Then invite several Ss to summarize the main idea of Text A.2.In-Depth Analysis1)Show Ss the following words and ask them to contribute to the class as muchas possible with what they know about these words. Provide additional information in Supplementary Information when necessary.•the invisible hand•free-market economy•economic downturn•An Inquiry into the Nature and Causes of the Wealth of Nations2)Explain some important language points in Language Support to Ss.3)Discuss with Ss the invisible hand in the author’s eyes by doing Task 1 inCritical reading and thinking.4)Organize a group discussion about the questions from Task 2 in Criticalreading and thinking. Encourage Ss to think independently, critically and creatively and share their ideas with each other.Supplementary Information1.free-market economyIn a free market economy, the laws and forces of supply and demand, rather than a central government, regulate production and labor. The prices for goods and services are self-regulated by buyers and sellers negotiating in an open market.Most companies and resources are not owned by the state. Instead, they are owned by private individuals or entities who are free to trade contracts with each other. 2.economic downturnAn economic downturn is a general slowdown in economic activity over a sustained period of time. It occurs when the value of stocks, property, and commodities fall, productivity either grows more slowly or declines, and GDP shrinks, stands still or expands more slowly. It can happen in a specific region (e.g.the Asian financial crisis in the late 1990s) or on a global scale (e.g. the global financial crisis in the late 2000s). The main features of an economic downturn include rising unemployment, falling share and house prices, low consumer confidence and declining investment.4.An Inquiry into the Nature and Causes of the Wealth of Nations(《国富论》)An Inquiry into the Nature and Causes of the Wealth of Nations, usually abbreviated as The Wealth of Nations, is Adam Smith’s masterpiece. It was first published in 1776, and is widely considered to be the first modern work in economics. Through reflection over the economics at the beginning of theIndustrial Revolution, the book touches upon broad topics such as the division of labor, productivity and free markets.Language Support1.Individual buyers and sellers will act according to what is in their own bestinterests. (Para. 2)The phrase “in one’s interest” means “for one’s benefit or advantage”(为了……的利益;为……着想). There are some relevant expressions, such as “in the interest of one”, “in one’s own interest”, and “in one’s best interest”.e.g. It’s obviously in their interest to increase profits.I suspect it’s in your own best interest to quit now.2.Customers are likewise typically looking out for their self-interests. (Para. 4)The word “likewise” is used to signal a comparison that explains how things are similar(同样的;此外).e.g. In this episode, we will likewise deal with another extremely commonquestion.Just water these plants twice a week, and likewise the ones in the bedroom.Other special words and expressions are often used to signal the comparison of two or more people, places, things, ideas, etc. Here are some examples of these signposts for your reference:similarly, both, just as, and also, resemble, parallel, in the same manner, inthe same way, alike, equally3.The market becomes more efficient as buyers and sellers move in the samedirection—as if directed by an invisible hand. (Para. 5)这里的as if用于省略句。

The study sample comprised 558 randomly selected women residents in Surulere, Nigeria. An interview was conducted by a standard questionnaire to obtain information. Research shows that the decline in breast-feeding in Nigeria is mainly due to the harsh realities of urban existence, which means extreme individual and community poverty. The current trend will not be reversed if the major structural defect of urban life in the developing world is not eliminated or controlled. Much can be done to educate the mothers on the use of hygienically acceptable supplementary foods from relatively inexpensive but nutritious locally available staple foods.Task 10 (Page 45)Breastfeeding Faces Challenges in ChinaUrbanization is closely linked to modernization, industrialization, and the sociological process of rationalization. Urbanization can describe a specif ic condition at a set time, i.e. the proportion of total population or area in cities or towns, or the term can describe the increase of this proportion over time. So the term urbanization can represent the level of urban development relative to overall population, or it can represent the rate at which the urban proportion is increasing.Upon hearing her baby wail, Zhang Shuyi finds herself at her wit’s end. Although she was previously confident that she would be able to breastfeed her child properly, she worries that she might not be able to give her baby enough milk.After giving birth to her son two years ago, 35-year-old Zhang, a doctor at the Capital Institute of Pediatrics in Beijing has continued to practice exclusive breastfeeding in strict accordance with international standards.Task 12 (Page 54)1) Para K Its topic sentence: Complex interactions between broad economic and socio-cultural factors inf luence infant-feeding practices in the developing countries.2) Para O Its topic sentence: Perhaps more lasting benefits will be achieved by emphasizing the education of mothers on how to prepare and use hygienically acceptable supplementary foods from relatively inexpensive but nutritious locally available staple foods.Academic Survival SkillsTask 1 (Page 58)Question 2S trong author version: Anyanwu (1985) claimed that “for most Nigerians, urban existence is synonymous with extreme individual and community poverty” for the great economic pressure on the mothers leave them little time to care adequately for their children.

Unit2 Energy for Planet Earth 课文翻译

Unit2 Energy for Planet Earth A课文翻译(学术综合英语教材(研究生课程)P52)能源转型能源资源价格低廉、使用便捷的时代已经过去,目前应向尽管价格较高、但污染较小的资源转变。

约翰∙R∙霍德雷恩了解这一转变,需首先考察一下能源和人类幸福的双重关系。

从积极的意义上说,能源为人类幸福作出了贡献,它为经济生产活动提供必要投人的同时,也提供了诸如取暖、照明等消费服务。

然而,人类为利用能源所付出的代价却削弱了能源为其带来的利益,这种代价不但包括为获取和利用能源所投人的资金和其他资源,而且包含了能源开发和利用所产生的环境影响和社会政治影响。

人类历史发展长河中,人们主要关心的是能源和人类安康等式关系中有利的一面。

能源资源不足或者(更经常)开采、加工和分配这些资源所需技术与机构的不足,会影响能源为人类带来利益,同时意味着能源的增长遭到干扰、损害或限制。

到了20世纪70年代,出现了一个转折点。

此前的几十年中,能源的资金成本一直保持稳定,甚或有所下降,而且,其所牵扯的环境成本和社会政治成本一直处于次要地位。

但20世纪70年代开始,开发和利用能源的多方成本均显著增长。

人们自然有理由认为:高昂的能源成本所带来的威胁已同能源供应不足所产生的危险不相上下。

同时,也有人担心,依靠扩大能源资源增加供应所需付出的代价,也许大于其所带来的利益。

20世纪90年代初期人们关注的焦点在于这种始于70年代的能源发展趋势是暂时的还是长远的。

廉价能源时代是真正一去不复返,还是通过开发新能源、应用新技术、改革地缘政治秩序等措施,有可能重登历史舞台?回答这个问题的一个关键因素是过去100 年以来因人口空前增长带来令人瞠目的能源需求以及同样使人无从应对的人均工业能源需求。

急剧增长的能源需求使得人类对能源的使用无所不用其极:不管是清洁煤炭还是劣质煤炭,见煤就挖;无论是陆上石油还是海底石油,深层气还是浅层气,见油气就采;水电站建设不论适宜与否,见水就上; 一边绿化造林以求燃料树木可持续发展,一边却砍树毁林。

Energy in TransitionThe era of cheap and convenient sources of energy is coming to an end. A transition to more expensive but less polluting sources must now be managed.John P. Holdren能源转型能源资源价格低廉、使用便捷的时代已经过去,目前应向尽管价格较高、但污染较小的资源转变。

约翰·P·霍德雷恩Understanding this transition requires a look at the two-sided connection between energy and human well-being. Energy contributes positively to well-being by providing such consumer services as heating and lighting as well as serving as a necessary input to economic production. But the costs of energy -including not only the money and other resources devoted to obtaining and exploiting it but also environmental and sociopolitical impacts -detract from well-being.了解这一转变,需首先考察一下能源和人类幸福的双重关系。

从积极的意义上说,能源为人类幸福作出了贡献,它为经济生产活动提供必要投入的同时,也提供了诸如取暖、照明等消费服务。

然而,人类为利用能源所付出的代价却削弱了能源为其带来的利益,这种代价不但包括为获取和利用能源所投入的资金和其他资源,而且包含了能源开发和利用所产生的环境影响和社会政治影响。

For most of human history, the dominant concerns about energy have centered on the benefit side of the energy -well-being equation. Inadequacy of energy resources or (more often) of the technologies and organizations for harvesting, converting, and distributing those resources has meant insufficient energy benefits and hence inconvenience, deprivation and constraints on growth. The 1970’s, then, represented a turning p oint. After decades of constancy or decline in monetary costs -and of relegation of environmental and sociopolitical costs to secondary status -energy was seen to be getting costlier in all respects.It began to be plausible that excessive energy costs could pose threats on a par with those of insufficient supply. It also became possible to think that expanding some forms of energy supply could create costs exceeding the benefits.人类历史发展长河中,人们主要关心的是能源和人类安康等式关系中有利的一面。

能源资源不足或者(更经常)开采、加工和分配这些资源所需技术与机构的不足,会影响能源为人类带来利益,同时意味着能源的增长遭到干扰、损害或限制。

到了20世纪70年代,出现了一个转折点。

此前的几十年中,能源的资金成本一直保持稳定,甚或有所下降,而且,其所牵扯的环境成本和社会政治成本一直处于次要地位。

但20世纪70年代开始,开发和利用能源的多方成本均显著增长。

人们自然有理由认为:高昂的能源成本所带来的威胁已同能源供应不足所产生的危险不相上下。

同时,也有人担心,依靠扩大能源资源增加供应所需付出的代价,也许大于其所带来的利益。

The crucial question at the beginning of the 1990’s is whether the trend that began in the 1970’s will prove to be temporary or permanent. Is the era of cheap energy really over, or will a combination of new resources, new technology and changing geopolitics bring it back? One key determinant of the answer is the staggering scale of energy demand brought forth by 100 years of unprecedented population growth, coupled with an equally remarkable growth in per capita demand of industrial energy forms. It entailed the use of dirty coal as well as clean; undersea oil as well as terrestrial; deep gas as well as shallow; mediocre hydroelectric sites as well as good ones; and deforestation as well as sustainable fuelwood harvesting.20世纪90年代初期人们关注的焦点在于这种始于70年代的能源发展趋势是暂时的还是长远的。

廉价能源时代是真正一去不复返,还是通过开发新能源、应用新技术、改革地缘政治秩序等措施,有可能重登历史舞台?回答这个问题的一个关键因素是过去100年以来因人口空前增长带来令人瞠目的能源需求以及同样使人无从应对的人均工业能源需求。

急剧增长的能源需求使得人类对能源的使用无所不用其极:不管是清洁煤炭还是劣质煤炭,见煤就挖;无论是陆上石油还是海底石油,深层气还是浅层气,见油气就采;水电站建设不论适宜与否,见水就上;一边绿化造林以求燃料树木可持续发展,一边却砍树毁林。

Except for the huge pool of oil underlying the Middle East, the cheapest oil and gas are already gone. Even if a few more giant oil fields are discovered, they will make little difference against consumption on today’s scale.Oil and gas will have to come increasingly, for most countries, from deeper in the earth and from imports whose reliability and affordability cannot be guaranteed.除了中东地区蕴藏着巨大的石油资源,地球上廉价的油气资源已经不复存在。

即使偶尔找到几个大油田,同当今巨大的能源消耗相比,也是杯水车薪。

对于大多数国家来说,油气资源越来越多地依赖于深层埋藏,越来越多地依赖进口,且不说进口油气资源的可靠性无法得到保障,其对进口国的支付能力也是一个考验。

There are a variety of other energy resources that are more abundant than oil and gas. Coal, solar energy, and fission and fusion fuels are the most important ones. But they all require elaborate and expensive transformation into electricity or liquid fuels in o rder to meet society’s needs. None has very good prospects for delivering large quantities of electricity at costs comparable to those of the cheap coal-fired and hydropower plants of the 1960’s. It appears, then, that expensive energy is a permanent condition, even without allowing for its environmental costs.诚然,其他许多资源的储藏量大于石油和天然气,最重要的有煤、太阳能、聚变裂变燃料等。

但这些资源转化成电力或液体燃料,以满足社会需求,均需经过技术复杂、成本昂贵的转化过程。

同20世纪60年代成本低廉的燃煤火电站和水力发电站相比,仅从成本角度考虑,以上各种资源用于大规模发电的可能性极小。

因此,即使不考虑能源开采的环保成本,能源价格居高不下已成无可改变的定局。

The capacity of the environment to absorb the effluents and other impacts of energy technologies is itself a finite resource. The finitude is manifested in two basic types of environmental costs. External costs are those imposed by environmental disruptions on society but not reflected in the monetary accounts of the buyers and sellers of the energy. “Internalized costs” are increases in monetary costs imposed by measures, such as pollution-control devices, aimed at reducing the external costs.环境吸纳由于能源利用而产生的废弃物和其他影响的能力本身也是有限度的,表现在两方面的环境成本上。
