The four types of sustainability include human, economic, social, andenvironmental. All four are required to maintain the entirety of life on Earth. Althoughinterconnected, itis importanttonotethedifferences of eachinterms ofits nature and requirements.The very basic need of humansustainability is good reproductive healthandsafe childbearing.Those that reproduce have the responsibility of caring for their children, giving them access to proper education, and promoting their health and wellness. At some point, the childrenshould have enoughskills and knowledge suchthatthey cansustaintheir ownway of life. Itis atthatpointthatthey becomeconsidered as productive human capital as well as individuals that can go through the process of reproduction and rearing. As long as this process is maintained at a rate that all human systems can support, human sustainability should be no cause for concern.Insimple terms, economic sustainability is havinga set amount of capital for acertain period. Those who consume that capital must also conserve it so that they will continue to enjoy it towards the end of the specified period. This means thatwe must preserve all our resources as we consume them so that human beings inthe future can enjoy them as well. To achieve this, we must regenerate our resources at a rate that is equal to or faster than our consumption.Social capital is an important aspect of sustainability because it is through communities and civil societies that humankind can easily and inexpensively work together. Without proper levels of social capital, it can easily deplete and violence as well as mistrustcantake over. Whenthathappens, societies andeverythingelsethat depends on them will be destroyed. Through proper maintenance of and adherencetolaws, rules, andvalues thatsocieties havedevelopedfor thecommongood, social sustainability can be achieved.Environmental sustainability is important because it involves natural resources that humanbeings need for economic or manufactured capital. Materials takenfromnature are usedfor solutions that address humanneeds. If nature is depletedfaster than it can regenerate, human beings will be left without raw materials.Furthermore,environmental sustainability also involves ensuring that waste emissions areatvolumes thatnaturecanhandle. If not, all humans andother livingthings on Earth can be harmed to the point of extinction.可持续性分类四种可持续性包括人类可持续性，经济可持续性，社会可持续性和环境可持续性。

科技英语课文翻译1-7
参考译文Unit 1课文A石油1油，和煤一样，存在于沉积岩中，而且可能由死去很长时间的生物有机体形成。
含有石油的岩石几乎都来源于海洋，所以形成石油的有机物一定是海洋生物，而不是树木。
2 石油，并不是来自于逐渐积聚的木质物质，而可能是来自于逐渐积聚的海洋生物的脂肪物质。
比如浮游生物：大量浮游在海水表层的单细胞生物。
3 有机物的脂肪物质主要由碳氢原子组成，因此并不需要太多的化学变化就可以形成石油。
生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。
其脂肪不是分解腐烂，而是逐渐积聚，并在深层的淤泥里圈闭起来，进而经过细微的原子重组，最终形成石油。
4 油比水轻，呈液态，会经由上方覆盖的孔隙性岩石向上渗透，在地球上有些地区到达表层，古人将这些表层石油称为沥青、柏油或异庚烷。
在古代和中世纪，这些石油油苗常被看作药品而不是燃料。
5 当然，表层的油苗数量很少。
而石油油藏上方有时覆盖的是非孔隙性岩石。
石油向上渗透抵达该岩石，然后在岩石下方逐渐积聚形成油层。
若在上方的岩石上钻个孔，石油就可以通过该孔向上迁移。
有时压力过大，石油会向高空喷出。
1859年在宾夕法尼亚州，由埃德温·德雷克成功打出第一口井。
6 如果可以发现一个合适的地点（勘探人员已经识别出地下可能圈闭有石油的地层结构），那么就很容易抽取这一液体燃料，这要比派人到地下把大块的固体煤炭砍成小块要容易得多。
而且一旦获得石油，可以通过地上管道运输，而不必像煤一样，由运货车经过繁重的装卸任务来运输。
7 石油便于抽取，易于运输，促进了石油的应用。
石油可以蒸馏成不同的馏分，每种馏分均由特定大小的分子组成，分子越小，该馏分就越容易蒸发。
8 到19世纪下半叶，最重要的石油馏分是由中等大小的分子构成的煤油，它不易蒸发，被用于照明。
9 然而，到19世纪末人们研制出了内燃机。
内燃机是通过在汽缸里将空气与可燃气体混合，产生爆炸来提供动力的。
最便利的可燃气体是汽油——石油的又一馏分，由小分子构成，容易蒸发。

科技英语翻译复习范围(DOC)1. 科技英语的语言特点具体表现一、大量使用名词化结构《当代英语语法》（A Grammar of Contemporary）在论述科技英语时提出，大量使用名词化结构（Nominalization）是科技英语的特点之一。
因为科技文体要求行文简洁、表达客观、内容确切、信息量大、强调存在的事实。
而非某一行为。
Archimeds first discovered the principle of displacement of water by solid bodies.阿基米德最先发展固体排水的原理。
句中of displacement of water by solid bodies 系名词化结构，一方面简化了同位语从句，另一方强调displacement 这一事实。
The rotation of the earth on its own axis causes the change from day to night.地球绕轴自转，引起昼夜的变化。
名词化结构the rotation of the earth on its own axis 使复合句简化成简单句，而且使表达的概念更加确切严密。
If you use firebricks round the walls of theboiler, the heat loss. Can be considerably reduced.炉壁采用耐火砖可大大降低热耗。
科技英语所表述的是客观规律，因之要尽量避免使用第一、二人称；此外，要使主要的信息置于句首。
Television is the transmission and reception of images of moving objects by radio waves.电视通过无线电波发射和接受活动物体的图象。
名词化结构the transmission and reception of images of moving objects by radio waves 强调客观事实，而"谓语动词则着重其发射和接受的能力。
二、广泛使用被动语句根据英国利兹大学John Swales 的统计，科技英语中的谓语至少三分之一是被动态。
这是因为科技文章侧重叙事推理，强调客观准确。
第一、二人称使用过多，会造成主观臆断的印象。
因此尽量使用第三人称叙述，采用被动语态，例如：Attention must be paid to the working temperature of the machine.应当注意机器的工作温度。
而很少说：You must pay attention to the working temperature of the machine .你们必须注意机器的工作温度。
此外，如前所述，科技文章将主要信息前置，放在主语部份。
这也是广泛使用被动态的主要原因。
试观察并比较下列两段短文的主语。
We can store electrical energy in two metal plates separated by an insulating medium. We call such a device a capacitor, or a condenser, and its ability to store electrical energy capacitance .It is measured in farads.电能可储存在由一绝缘介质隔开的两块金属极板内。
这样的装置称之为电容器，其储存电能的能力称为电容。
电容的测量单位是法拉。
这一段短文中各句的主语分别为：Electrical energySuch a deviceIts ability to store electrical energyIt (Capacitance )它们都包含了较多的信息，并且处于句首的位置，非常醒目。
四个主语完全不同，避免了单调重复，前后连贯，自然流畅。
足见被动结构可收简洁客观之效。
三、非限定动词。
如前所述，科技文章要求行文简练，结构紧凑，为此，往往使用分词短语代替定语从句或状语从句；使用分词独立结构代替状语从句或并列分句；使用不定式短语代替各种从句；介词十动名词短语代替定语从句或状语从句。
这样可缩短句子，又比较醒目。
试比较下列各组句子。
A direct current is a current flowing always in the same direction.直流电是一种总是沿同一方向流动的电流。
Radiating from the earth, heat causes air currents to rise.热量由地球辐射出来时，使得气流上升。
A body can more uniformly and in a straight line,there being no cause to change that motion.如果没有改变物体运动的原因，那么物体将作匀速直线运动。
Vibrating objects produce sound waves ,each vibration producing one sound wave.振动着的物体产生声波，每一次振动产生一个声波。
In communications, the problem of electronics is how to convey information from one place to another.在通讯系统中，电子学要解决的问题是如何把信息从一个地方传递到另一个地方。
Materials to be used for structural purposes are chosen so as to behave elastically in the environmental conditions.结构材料的选择应使其在外界条件中保持其弹性。
There are different ways of changing energy from one form into another.将能量从一种形式转变成另一种形式有各种不同的方法。
In making the radio waves correspond to each sound in turn ,messages are carried from a broadcasting station to a receiving set.使无线电波依次对每一个声音作出相应变化时，信息就由广播电台传递到接收机。
四、后置定语大量使用后置定语也是科技文章的特点之一。
常见的结构不以下五种：1、介词短语The forces due to friction are called frictional forces.由于摩擦而产生的力称之为摩擦力。
A call for paper is now being issued .征集论文的通知现正陆续发出。
2、形容词及形容词短语。
In this factory the only fuel available is coal.该厂唯一可用的燃料是煤。
In radiation ,thermal energy is transformed into radiant energy ,similar in nature to light.热能在辐射时，转换成性质与光相似的辐射能。
3、副词The air outside pressed the side in .外面的空气将桶壁压得凹进去了。
The force upward equals the force downward so that the balloon stays at the level.向上的力与向下的力相等，所以气球就保持在这一高度。
4、单个分词，但仍保持校强的动词意义。
The results obtained must be cheeked .获得的结果必须加以校核The heat produced is equal to the electrical energy wasted.产生的热量等于浪费了的电能。
5、定语从句During construction, problems often arise which require design changes.在施工过程中，常会出现需要改变设计的问题。
The molecules exert forces upon each other, which depend upon the distance between them.分子相互间都存在着力的作用，该力的大小取决于它们之间的距离。
Very wonderful changes in matter take place before our eyes every day to which we pay little attention.我们几乎没有注意的很奇异的物质变化每天都在眼前发生。
To make an atomic bomb we have to use uranium 235,in which all the atoms are available for fission.制造原子弹，我们必须用铀235，因为轴的所有原子都会裂变。
五、常用句型科技文章中经常使用若干特定的句型，从而形成科技文体区别于其他文体的标志。
例如It——that——结构句型；被动态结构句型；结构句型，分词短语结构句型，省略句结构句型等。
举例如下：It is evident that a well lubricated bearing turns more easily than a dry one .显然，润滑好的轴承，比不润滑的轴承容易转动。
It seems that these two branches of scienceare mutually dependent and interacting .看来这两个科学分支是相互依存，相互作用的。
It has been proved that induced voltage causes a current to flow in opposition to the force producing it.已经证明，感应电压使电流的方向与产生电流的磁场力方向相反。
It was not until the 19th century that heat was considered as a form of energy.直到十九世纪人们才认识到热是能量的一种形式。
Computers may be classified as analog and digital.计算机可分为模拟计算机和数字计算机两种。
