The End Is Not at Hand

The environmental rhetoric overblown.

The planet will survive

Robert J. Samuelson

并非末日来临

环境问题言过其实,地球生命仍将继续。

罗伯特·J·塞缪尔森

[ 1 ] Whoever coined the phrase "save the planet" is a public relation genius. It conveys the sense of impending* catastrophe* and high purpose that has wrapped environmentalism in an aura* of moral urgency. It also typifies environmentalism's rhetorical excesses, which, in any other context, would be seen as wild exaggeration* or simple dishonesty.

[1] 无论是谁杜撰了“拯救地球”这一说法,他都是一位公共关系方面的天才。这一说法既表达了对即将来临的灭顶之灾的意识,也满怀着使环境保护论带有道义紧迫感这一大的目标。同时这种说法也表明环境保护论言过其实,这种夸大在其他任何场合都会被视为是在危言耸听或愚蠢的欺骗。

[ 2 ] Up to a point, our environmental awareness has checked a mindless enthusiasm for unrestrained economic growth.We have sensibly curbed* some of growth's harmful side effects. But environmentalism increasingly resembles a holy crusade* addicted to hype* and ignorant of history. Every environmental ill is depicted* as an onrushing calamity* that—if not stopped will end life as we know it.

[2] 就某种程度而言,我们的环境意识遏制了对自由经济增长所表现出的盲目热情。我们已明智地抑制了增长中所出现的一些有害的副作用,但是环境保护论却越来越像一场沉湎于狂热的宣传与对历史一无所知的圣战。每一由环境问题引发的不幸都被描绘成一场势不可挡的灾难。这场灾难如不加以制止,正像我们所知晓的那样,就会摧毁生命。

[ 3 ] Take the latest scare: the greenhouse effect①. We' re presented with the horrifying specter* of a world that incinerates* itself.Act now, or sizzle* later. Food supplies will wither. Glaciers* will melt. Coastal areas will flood. In fact, the probable losses from any greenhouse warming are modest*: 1 to 2 percent of our economy's output by the year 2050, estimates economist William Cline①.The loss seems even smaller compared with the expected growth of the economy (a doubling) over the same period.

[3] 以最近出现的恐慌——温室效应——为例。展现在我们面前的是一个自我焚毁、可怕的幽灵般的世界。即刻行动,否则世界将咝咝烧焦。食品供应即将枯竭。冰川即将溶化。沿海地区即将淹没。事实上,任何温室热效应可能造成的损失都是有限的:经济学家威廉·克莱恩估计,到 2050 年只占我们经济产出的 1% 到 2%。与预想的同期经济增长(翻一番)相比,这一损失更显得微不足道。

[ 4 ] No environmental problem threatens the "planet" or rates with the danger of a nuclear war.No oil spill ever caused suffering on a par with* today's civil war in Yugoslavia, which is a minor episode* in human misery. World WarⅡleft more than 35 million dead. Cambodia's civil war resulted in 1 million to 3 million deaths.The great scourges* of humanity remain what they have always been: war, natural disaster, oppressive government, crushing poverty and hate. On

any scale of tragedy, environmental distress is a featherweight*.

[4] 没有任何环境问题威胁这颗“星球”,任何环境问题都无法用核战争所带来的危害来衡量。任何石油溢出造成的危害也无法同今日南斯拉夫内战——它不过是人类苦难中的一段小插曲——相比拟。第二次世界大战导致 3 500 多万人死亡。柬埔寨内战导致 100 万至300 万人死亡。人类的巨大祸患一如既往:战争、自然灾害、暴虐政府、极度的贫困与仇恨。在悲剧的任何尺度上,环境问题造成的痛苦都轻如鸿毛。

[ 5 ] This is not an argument for indifference or inaction. It is an argument for perspective and balance. You can believe (as I do) that the possibility of greenhouse warming enhances an already strong case for an energy tax.A tax would curb ordinary air pollution, limit oil imports, cut the budget deficit* and promote energy efficient investments that make economic sense.

[5] 这并非在为漠不关心或无动于衷进行辩解,这是在为前途和平衡而进行

辩论。你可以相信( 像我那样),温室热效应的可能性强化了已具说服力的征缴

能源税的理由。税收会抑制通常的空气污染,限制石油进口,减少预算赤字并提

高具有经济意义的能效投入。

[ 6 ] But it does not follow that anyone who disagrees with me is evil or even wrong.On the greenhouse effect, for instance, there‘s ample* scientific doubt over whether warming will occur and, if so, how much. Moreover, the warming would occur over decades. People and businesses could adjust. To take one example: farmers could shift to more heat-resistant seeds.

[6] 但这并非意味着同我观点相悖的人就是居心叵测,或甚至是错误的。例如,就温室效应而言,热效应是否会发生,如果发生,其程度如何,对这类问题还存在大量的科学疑问。此外,热效应的发生需几十年的时间。人与行业可以进行调整。举一例:农民可改用更为耐热的种子。

[ 7 ] Unfortunately, the impulse of many environmentalists is to vilify* and simplify. Critics of environmental restrictions are portrayed* as selfish and ignorant creeps*. Doomsday scenarios* are developed to prove the seriousness of environmental dangers. Cline‘s recent greenhouse study projected warming 250 years into the future. Guess what, it increases sharply. This is an absurd exercise akin to* predicting life in 1992 at the time of the French and Indian War (1754~1763).

[7] 遗憾的是,许多环境保护论者感情用事,搞中伤和将事情简单化。环境限制法的批评者被描绘为自私自利、愚昧无知的小人。有关世界末日的电影剧本被创作出来以证实环境危险的严重性。克莱恩最近对温室效应的研究展现了热效应在今后250 年间的变化。猜猜吧,结果是什么? 它在急剧增长。这就类似于一种在法印战争(1754—1763)时期预言1992 的生活的无稽之谈。

[ 8 ] The rhetorical overkill is not just innocent excess. It clouds our understanding. For starters, it minimizes the great progress that has been made, especially in industrialized countries. In the United States, air and water pollution have dropped dramatically*.

Since 1960, particulate* emissions (soot, cinders*) are down by 65 percent. Lead emissions have fallen by 97 percent since 1970. Smog has declined in most cities.

[8] 大谈特谈过多的伤亡并非过分的无知,它混淆人们的视听。对工业刚起步的国家来说,它低估了特别是工业化国家已取得的巨大成就。在美国,空气与水污染已得到显著缓解。自1960 年以来,微颗粒物排放量(煤灰、煤渣)已下降65%。自1970 年以来,铅排放量已降低97%。在大多数城市中,烟雾已减少。

[ 9 ] What's also lost is the awkward necessity for choices. Your environmental benefit may be my job. Not every benefit is worth having at any cost.Economists estimate that environmental

regulations depress the economy's output by 2.6 to 5 percent, or about $150 billion to $290 billion. (Note: this is larger than the estimated impact of global warming.) For that cost, we've lowered health risks and improved our surroundings. But some gains are small compared with the costs. And some costs are needlessly high because regulations are rigid.

[9] 同时我们也受到损失。这就是必须进行棘手的选择。你在环保方面所得到的好处也许就是我应尽的义务。并非每种利益都值得不惜任何代价而求之。经济学家估计,环境法规使经济产出下降2.6% 至5%,或1 500 亿至2 900 亿美元(注:这一数字大于全球热效应的估计影响)。我们用这一代价的确减轻了给身体所带来的危害,并且改善了我们的环境。但是,有些却得不偿失,而且由于法规的刻板僵化而使得一些代价毫无必要地上升。

[ 10 ] Balance: The worst sin of environmental excess is its bias* against economic growth. The cure for the immense problems of poor countries usually lies with economic growth. A recent report from the World Bank estimates that more than 1 billion people lack healthy water supplies and sanitary* facilities.The result is hundreds of millions of cases of diarrhea* annually and the deaths of 3 million children (2 million of which the World Bank judges avoidable). Only by becoming wealthier can countries correct these conditions.

[10] 平衡:过分夸大环境作用的最大罪过是对经济增长所执的偏见。解决贫困国家所存在的大量问题通常与经济增长息息相关。世界银行最近的一份报告估计,10 亿多人缺少健康用水和卫生设施。其结果是每年成千百万人患痢疾,并导致300 万儿童死亡(世界银行认为,其中200 万人可以免于死亡)。国家只有变得富裕起来才能改变这些状况。

[ 11 ] Similarly, wealthier societies have both the desire and the income to clean their air and water. Advanced nations have urban-air-pollution levels only a sixth that of the poorest countries. Finally, economic growth tends to reduce high birthrates, as children survive longer and women escape traditional roles.

[11] 与此同理,较富庶的国家既具有愿望也具有财政收入来净化空气和用水。发达国家的城市空气污染仅为贫穷国家的六分之一。最终,经济增长将降低高的出生率,因为儿童寿命延长了,妇女也摆脱了传统的角色。

[ 12 ] Yes, we have environmental problems. Reactors* in the former Soviet Union pose safety risks. Economic growth and the environment can be at odds*. Growth generates carbon dioxide emissions and causes more waste. But these problems are not - as environmental rhetoric implies - the main obstacles to sustained development. The biggest hurdle is inept * government.

Inept government fostered* unsafe reactors. Inept government hampers* food production in poor countries by, say, preventing farmers from earning adequate returns on their crops.

[12] 的确,我们存在环境问题。苏联的反应堆给安全造成威胁。经济增长与环境会发生矛盾。增长产生二氧化碳排放物,并且造成更多的废弃物。但是这些问题并不像环境保护论者夸夸其谈的那样,是持续发展的主要障碍。最大的障碍是无能的政府。无能的政府培育出无安全保障的反应堆。在贫穷的国家,无能的政府,比如说,通过限止农民从其作物中获得适当的利润,阻碍食品生产。

[ 13 ] By now, everyone is an environmentalist. But the label is increasingly meaningless, because not all environmental problems are equally serious and even the serious ones need to be balanced against other concerns. Environmentalism should hold the hype. It should inform us more and frighten us less.

[13] 到现在为止,人人都是环境保护论者,但是这种说法越来越没有意义,因为并非一切环境问题都同样严重,甚至即使那些严重的环境问题也需要同其他利害关系来均衡考虑。环境保护论应当终止那种刺激性宣传。它应当给予我们更多一些信息,更少一些恐吓。

Suggested passage:

In recent years we have become increasingly conscious of our duty

towards the environment. People have begun to realize that just because

we are so dependent on natural resources, we must learn to conserve

them, so that they will still be available for future generation.

In modern times, man has exploited the earth to an alarming degree

with the effect that he is in danger of destroying the very environment that gives him life. An example of over exploitation is the destruction of forest reserves, which play a vital part in the ecology of the earth. Not only are

our forests in danger, but as a result of industrialization seas and rivers have become polluted, and this is causing the fish in them to be poisoned

and drinking water to be contaminated. Pollution of the atmosphere with

gases is not only affecting the quality of the air we breathe, but may also result in raising the temperature of the earth to dangerous levels.

In view of the seriousness of this problem, people are starting to take measures. They are now getting to know that it is man’s responsibility to conserve nature in order to ensure his own survival and well-being.

Lesson One: The Time Message Elwood N, Chapman 新的学习任务开始之际,千头万绪,最重要的是安排好时间,做时间的主人。本文作者提出了7点具体建议,或许对你有所启迪。 1 Time is tricky. It is difficult to control and easy to waste. When you look a head, you think you have more time than you need. For Example,at the beginning of a semester, you may feel that you have plenty of time on your hands, but toward the end of the term you may suddenly find that time is running out. You don't have enough time to cover all your duties (duty), so you get worried. What is the answer? Control! 译:时间真是不好对付,既难以控制好,又很容易浪费掉,当你向前看时,你觉得你的时间用不完。例如,在一个学期的开始,你或许觉得你有许多时间,但到学期快要结束时,你会突然发现时间快用光了,你甚至找不出时间把所有你必须干的事情干完,这样你就紧张了。答案是什么呢?控制。 2 Time is dangerous. If you don't control it, it will control you. I f you don't make it work fo r you, it will work against you. So you must become the master of time, not its servant. As a first-year college student, time management will be your number one Problem. 译:时间是危险的,如果你控制不了时间,时间就会控制你,如果你不能让时间为你服务,它就会起反作用。所以,你必须成为时间的主人,而不是它的奴仆,作为刚入学的大学生,妥善安排时间是你的头等大事。 3 Time is valuable. Wasting time is a bad habit. It is like a drug. The more time you waste,the easier it is to go on wasting time. If seriously wish to get the most out of college, you must put the time message into practice. 译:时间是珍贵的,浪费时间是个坏习惯,这就像毒品一样,你越浪费时间,就越容易继续浪费下去,如果你真的想充分利用上大学的机会,你就应该把利用时间的要旨付诸实践。 Message1. Control time from the beginning. 4 Time is today, not tomorrow or next week. Start your plan at the Beginning of the term. 译:抓紧时间就是抓紧当前的时间,不要把事情推到明天或是下周,在学期开始就开始计划。 Message2. Get the notebook habit. 5 Go and buy a notebook today, Use it to plan your study time each day. Once a weekly study plan is prepared, follow the same pattern every week with small changes. Sunday is a good day to make the Plan for the following week.

Exploring Filipino School Counselors’ Beliefs about Learning Allan B. I. Bernardo [Abstract] School reform efforts that focus on student learning require school counselors to take on important new roles as advocates of student learning and achievement.But how do school counselors understand the process of learning? In this study, we explore the learning beliefs of 115 Filipino school counselors who indicated their degree of agreementwith 42 statements about the process of learning and the factors thatinfluence this process.A principal components analysis of the responses to the 42 statements suggested three factors:(F1)social-cognitive constructivist beliefs, (F2) teacher-curriculum-centered behaviorist beliefs,and (F3) individual difference factors.The preliminary results are briefly discussed in terms of issues related to how Filipino school counselors’ conceptions of learning may guide their strategies for promoting student learning and achievement. [Key words]beliefs about learning, conceptions of learning, school counselors, student learning, Philippines School reform efforts in different parts of the world have focusedon students’learning. In particular,most school improvement programsnow aim to ensure that students acquire the high-level knowledge and skills that help them to thrive in today’s highly competitive globaleconomy (e.g., Lee & Williams, 2006). I n this regard, school reform programs draw from various contemporary theories and research on learning (e.g.,Bransford,Brown, & Cocking, 1999; Lambert & McCombs, 1998).The basic idea is that all school improvement efforts should be directed at ensuring students achieve high levels of learning or attainment of well-defined curricular objectives and standards.For example, textbooks (Chien & Young, 2007), computers and educational technology (Gravoso, 2002; Haertnel & Means, 2003;Technology in Schools Task Force, 2003), and educational assessment systems (Black & Wiliam2004; Cheung & Ng, 2007; Clark, 2001; Stiggins, 2005) are being reconsidered as regards how they can effectively provide scaffolds and resources for advancing student learning. Likewise,the allocation and management of a school’s financial resources are assessed in terms ofwhether these are effectively mobilized and utilized towards improving student learning (Bolam, 2006; Chung & Hung, 2006; Retna, 2007). In this regard, some advocates have also called for an examination of the role of school counselors in these reform efforts (Herr, 2002). Inthe United States, House and Hayes (2002) challenged school counselors to take proactive leadership roles in advocating for the success of all

GRA VITY RETAINING?WALL 1. INTRODUCTION Retaining walls are structures used to provide stability for earth or other material where conditions disallow the mass to assume its natural slope, and are commonly used to hold back or support soilbanks,coal or ore piles, and water. Retaining walls are classified, based on the method of achieving stability, into six principal types (Fig.1). The gravity-wall depends upon its weight, as the name implies, for stability. The cantilever wall is a reinforced-concrete wall that utilizes cantilever action to retain the mass behind the wall from assuming a natural slope. Stability of this wall is partially achieved from the weight of soil on the heel portion of the base slab. A counterfort retaining wall is similar to a cantilever retaining wall, except that it is used where the cantilever is long or for very high pressures behind wall and has counterforts, which tie the wall and base together, built at intervals along the wall to reduce the bending moments and sheers. As indicated in Fig.1c, the counterfort is behind the wall and subjected to tensile forces. A buttressed retaining wall is similar to a counterfort wall, except that the bracing is in front of the wall and is in compression instead of tension. Two other types of walls not considered further are crib walls, which are built-up members of pieces of precast concrete, metal, or timber and are supported by anchor pieces embedded in the soil for stability, and semigravity walls, which are walls intermediate between a true gravity and a cantilever wall.

高速视频处理系统中的信号完整性分析 摘要:结合高速DSP图像处理系统讨论了高速数字电路中的信号完整性问题,分析了系统中信号反射、串扰、地弹等现象破坏信号完整性的原因,通过先进IS工具的辅助设计,找出了确保系统信号完整性的具体方法。 关键词:高速电路设计信号完整性 DSP系统 深亚微米工艺在IC设计中的使用使得芯片的集成规模更大、体积越来越小、引脚数越来越多;由于近年来IC工艺的发展,使得其速度越来越高。从而,使得信号完整性问题引起电子设计者广泛关注。 在视频处理系统中,多维并行输入输出信号的频率一般都在百兆赫兹以上,而且对时序的要求也非常严格。本文以DSP图像处理系统为背景,对信号完整性进行准确的理论分析,对信号完整性涉及的典型问题[1]——不确定状态、传输线效应、反射、串扰、地弹等进行深入研究,并且从实际系统入手,利用IS仿真软件寻找有效的途径,解决系统的信号完整性问题。 1 系统简介 为了提高算法效率,实时处理图像信息,本图像处理系统是基于DSP+FPGA结构设计的。系统由SAA7111A视频解码器、TI公司的TMS320C6701 DSP、Altera公司的EPlK50QC208 FPGA、PCI9054 PCI接口控制器以及SBRAM、SDRAM、FIFO、FLASH等构成。FPGA是整个系统的时序控制中心和数据交换的桥梁,而且能够对图像数据实现快速底层处理。DSP是整个系统实时处理高级算法的核心器件。系统结构框图如图1所示。 在整个系统中,PCB电路板的面积仅为15cm×l5cm,系统时钟频率高达167MHz,时钟沿时间为0.6ns。由于系统具有快斜率瞬变和极高的工作频率以及很大的电路密度,使得如何处理高速信号问题成为一个制约设计成功的关键因素。 2 系统中信号完整性问题及解决方案 2.1 信号完整性问题产生机理 信号的完整性是指信号通过物理电路传输后,信号接收端看到的波形与信号发送端发送的波形在容许的误差范围内保持一致,并且空间邻近的传输信号间的相互影响也在容许的范围之内。因此,信号完整性分析的主要目标是保证高速数字信号可靠的传输。实际信号总是存在电压的波动,如图2所示。在A、B两点由于过冲和振铃[2]的存在使信号振幅落入阴影部分的不确定区,可能会导致错误的逻辑电平发生。总线信号传输的情况更加复杂,任何一个信号发生相位上的超前或滞后都可能使总线上数据出错,如图3所示。图中,CLK为时钟信号,D0、D1、D2、D3是数据总线上的信号,系统允许信号最大的建立时间[1]为△t。在正常情况下,D0、D1、D2、D3信号建立时间△t1<△t,在△t时刻之后数据总线的数据已稳定,系统可以从总线上采样到正确的数据,如图3(a)所示。相反,当信号D1、D2、D3受过冲和振铃等信号完整问题干扰时,总线信号就发生
