然而,既然从泰德·特纳到乔治·.布什,每个人都声称自己热爱地球母亲,那么,在由议员、选民之类的人以环境名义而提出的众多的相互矛盾的提案、规章和法规中,我们又该如何做出选择呢显而易见 ,并不是每一项冠以环境保护名义的事情都值得去做。
我们怎样才能别离出最正确选择,并且把我们各自不同的兴趣统一在同一个合理的政策当中呢2Thereisasimpleway.First,differentiatebetweenenvironmentalluxuriesandenvironmental necessities.Luxuriesarethosethingsthatwouldbenicetohaveifcostless.Necessitiesarethosethi ngswemusthaveregardless.Callthisdistinctionthedefinitiveruleofsaneenvironmentalism,which stipulatesthatcombatingecologicalchangethatdirectlythreatensthehealthandsafetyofpeopleis anenvironmentalnecessity.Allelseisluxury.有一种简便的方法。
Four Laws of Ecology生态学四法则这是一门年轻的科学,它所教的很多内容都是从地球上的整个生命之网的小环节上所得到的。
生态学还没有明确发展为一种结构严密的、或者说是由物理学的规律检验过的简化了的概括原则。
不过,仍然有很多法则对我们现在所认识的生态圈已经是很明显的了,它们可以组成一种通俗的“生态学法则”。
这就是下面所要论述的。
生态学的第一条法则:每一种事物都与别的事物相关。
在不同这时,例如,研这就这样线上运行并非总是稳定不变的,不过它最终还是要在它摇摆于真实的航线的起伏不停的运动中遵循总的方向。
这些摇摆的频率是以其循环中的各个步骤中的相对速度所决定的,如船在船舵转动时所做出的反应时的速度。
生态系统也现出类似的循环,尽管这些循环受到多种多样的天气和环境的各种媒介的日常或季节的影响,而常常是不太明显的。
这类生态学上的摆动的最为明显的例子是毛皮动物种群大小的阶段式的变化。
例如,在加拿大的动物捕猎史上,兔子和山猫的种群是以十年为一转折的。
当兔子很多时,山猫的繁殖也很快,山猫种群的增大越来越多地影响到兔子的种群,使它减少下来;当兔子变得稀少时,也就没有足够的食物维持大量的山猫了;当山猫开始死去时,兔子所受的威胁也就较少些,于是数量开始增加。
如此循环往复。
这些变化成为简单循环的组成部分,在这种循环中,山猫种群无疑是与兔子种群有关,而兔子种群也反过来与山猫种群有关。
在这种摆动系统中总存在着一种危险,即整个系统在这种摆动中的辐度超出于平衡点,以致这个系统不能再恢复它的正常水准时,整个系统就将崩溃。
例如,假定在兔子——山猫循环周期的一部分摆动中,山猫设法吃掉了所有的兔子(或者就只剩了一只了),这样,兔子的种群就不可能再繁殖了。
在正常的情况下,当兔子被吃掉时,山猫就要开始挨饿,但这一次,山猫种群减少之后是再不会有兔子数量的增加了。
结果,山猫就要死去。
整个兔子——山猫的体系也就崩溃了。
这与伴随着生态上的崩溃的那种被称为“富营养”的情况是相同的。
Unit 5Speaking Chinese in America在美国说中文Once, at a dinner on the Monterey Peninsula, California, my mother whispered to me confidentially: "Sau-sau (brother's wife) pretends too hard to be a polite recipient! Why bother with such nominal courtesy? In the end, she always takes everything."有一次,在加州蒙特雷半岛上用餐时,我母亲私下悄悄地对我说:“嫂嫂想做个彬彬有礼的客人,但是装得太厉害了!何必费劲讲究形式上的客套呢?到最后她还是什么都要。
”My mother acted like a waixiao, an emigrant, no longer patient with old taboos and courtesies. To prove her point, she reached across the table to offer my elderly aunt from Beijing the last scallop from the garlic seafood dish, along with the flank steak and the cucumber salad.我母亲行事像个“外侨”,即一个移民国外的侨民,因为她已经不耐烦老一套的禁忌和礼数了。
为了证明她刚才的观点,她手伸过桌子,把蒜香海鲜拼盘里的最后一个扇贝,连同牛腩排及黄瓜沙拉一起,递给我从北京来的年长舅妈。
Sau-sau frowned. "B'yao, zhenb'yao!" she cried, patting her substantial stomach. I don't want it, really I don't.嫂嫂皱起了眉头,“不要,真不要!”她一边大声说一边拍着自己已经吃得很饱的肚子。
Lesson 12 Four Laws of Ecology (Part II)一、词汇短语1. pervasive [] adj. existing everywhere到处存在的,到处弥漫着的:The fact that so many people have posted comments on this topicshows how pervasive and complicated it is.事实上这么多人公开谈论这个话题,就已经表明这是多么普遍多么复杂的事情。
2. detrimental [] adj. causing harm or damage有害的,不利的:The policy will be detrimental to the peace process.这项政策不利于和平进程。
3. analogy []n. something that seems similar between twosituations, processes, etc.类似处,相似处4. finite [] adj. having an end or a limit 有限的,有限度的:Humanknowledge is finite, ie there are things we do not know. 人类的认识是有限的。
5. improbable [] adj. not likely to happen or to be true 不大可能发生的,未必确切的:As improbable as this sounds, it really works.听起来有点不可思议,但这是真的。
6. self-evident [] adj. clearly true and needing no moreproof不证自明的,显而易见的:It seems to me self-evident that policesearches of newspaper offices burden the freedom of the press.警察对报社的搜查给新闻自由造成压力,这在我看来是不言而喻的。

Four Laws of Ecology1 In broad outline,there are environmental cycles which govern the behavior of the three great global systems:the air,the water,and the soil.Within each of them live many thousands of different species of living things.Each species is suited to its particular environmental niche,and each,through its life processes,affects the physical and chemical properties of its immediate environment.1概括来讲,地球的三大系统—空气、水和土壤的行为由环境循环所决定。
每个系统中都生活着成千上万个不同物种的生物,每个物种都有与之相适宜的独特的环境生位,并且每一物种,在其整个生命历程中,都影响着它的周边环境的物理和化学特性。
2 Each living species is also linked to many others.These links are bewildering in their variety and marvelous in their intricate detail.An animal,such as a deer,may depend on plants for food;the plants depend on the action of soil bacteria for their nutrients;the bacteria in turn live on the organic wastes dropped by the animal on the soil.At the same time.the deer is food for the mountain lion. Insects may live on the juices of plants or gather pollen from their flowers.Other insects suck blood from animals.Bacteria may live on the internal tissues of animals and plants.Fungi degrade the bodies of dead plants and animals.All this,many times multiplied and organized species by species in intricate,precise relationships,makes up the vast network of life on the earth.2每个生物物种也与许多其他的物种相联系。
1.这些联系的多样性令人迷惑不解,其错综复杂的细节令人惊叹不已。
某一动物,如一只鹿,可能依靠植物来获取食物;植物依靠土壤细菌的活动来获取其营养;相应地,细菌以陆地上的动物排泄出来的有机废物为生。
同时,鹿是美洲狮的食物。
昆虫可能以植物的汁液为生,或者从其花朵里采集花粉。
其他的昆虫则吸吮动物的血液。
细菌可能以动物和植物的内部组织为生。
真菌分解死亡的植物和动物的躯体。
所有这一切,由各个物种通过复杂而严密的关系多次繁殖和组织,构成了地球上巨大的生命之网。
3 The science that studies these relationships and the processes linking each living thing to the physical and chemical environment is ecology.It is the science of planetary housekeeping For theenvironment is,so to speak,the house created on the earth by living things for living things.It is a young science and much of what it teaches has been learned from only small segments of the whole network of life on the earth Ecology has not yet explicitly develop the kind of cohesive, simplifying generalizations exemplified by,say,the laws of physics.Nevertheless there are a number generalizations that are already evident in what we now know about the ecosphere and that can be organized into a kind of informal set of laws of ecology.These are described in what follows3研究这些关系以及把每种生物与物理和化学环境相联系的过程的科学是生态学。
它是行星家政科学。
2.因为环境,可以说,是地球上由生物创造并为生物所用的家园。
这是一门年轻的科学,而且它所讲述的大部分内容都是从地球整个生命之网的仅仅一小部分上所得来的。
生态学还没有明确形成,比如说,像物理学定律那样联系紧密的、简化的一般法则。
不过,在我们现在对生态圈的认识方面,有许多一般法则已经显而易见,它们可以组成一套通俗的“生态学法则”。
这些法则表述如下。
The First Law of Ecology:Everything Is Connected to Everything Else生态学的第一条法则每一个事物都与其他事物相关4 Some of the evidence that leads to this generalization has already been discussed.It reflects the existence of the elaborate network of interconnections in the ecosphere:among different living organisms,and between populations,species,and individual organisms and their physicochemical surroundings4得出这条一般法则的一些证据已经讨论过了。
它反映了生态圈中存在着相互联系的复杂网络:这个网络存在于不同的生物体中,存在于种群、物种和个体生物与其物理化学环境之间5 The single fact that an ecosystem consists of multipleinter connected parts,which act on one another,has some surprising consequences.Our ability to picture the behavior of such systems has been helped considerably by the development,even more recent than ecology,of the science of cybernetics.We owe the basic concept,and the word itself,to the inventive mind of the lateNorbert wiener.5一个生态系统由很多相互联系的部分组成,它们相互作用,仅仅这个事实就产生了一些令人惊奇的结果。
控制论这一学科的发展极大地提高了我们描述这类系统行为的能力,而它的发展甚至比生态学还晚3我们把这一基本概念以及这个回本身的产生都归功于已故的诸伯特·威纳的有创造力的头脑6 The word cybernetics derives from the Greek word for helmsman";it is concerned with cycles of events that steer,or govern,the behavior of a system.The helmsman is part of a system that also includes the compass,the rudder,and the ship.If the ship veers off the chosen compass course,the change shows up in the movement of the compass needle Observed and interpreted by the helmsman this event determines a subsequent one:the helmsman turns the rudder,which swings the ship back to its original course. When this happens,the compass needle returns to its original,on course position and the cycle is complete.If the helmsman turns the rudder too far in response to a small deflection of the compass needle,the excess swing of the ship shows up in the compass which signals the helmsman to correct his overreaction by an opposite movement.Thus the operation of this cycle stabilizes the course of the ship.6控制论一词源于希腊语中的“舵手”一词:它与操纵或控制某一系统行为的事件发生的周期有关。
