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。

Sentence TranslationUnit 1Text A1.However, the volume of business done on the Internet is growing rapidly, as people orderbooks and other products to make money transactions.但是，因特网上的交易数量急速增长，人们从网上购书和其他的产品，进行资金交易。

2.They use them to prowl the Internet, looking for ways to break into computers systems runby banks, telephone companies and even government departments.他们用电脑上网，寻找能够进入银行电脑系统、电话公司的电脑系统、甚至是政府的电脑系统的方式。

3.The first indication of a security breach may be when a customer discovers a fraudulentmoney transaction on a credit card account.当顾客发现信用卡的帐号上出现了来历不明的消费时，这可能就是安全受到了破坏的第一个标志。

4.The use of credit cards to buy things on the Internet converts the issue of Internet securityinto one of general security.用信用卡在网上购物使网络安全变成了大众所普遍关注的安全的一种5.Few people think twice about giving a credit card number over the phone and many areequally careless about what happens to the carbon copy when completing a transaction over the counter.很多人会在电话里随意报出自己的信用卡号码，同样地，也有很多人不留意交易完成后放在银行柜台上的副本。

科技英语的特点与翻译一、科技英语的特点科技英语（English for science and technology，EST）指与用于科学和技术交流方面的英语口语和书面语。

作为一种重要的英语语体，其特点主要体现在以下几个方面。

1、词汇方面大量使用专业词汇、复合词、缩略词及利用前后缀构成的派生词。

专业词汇意义专一，用来表示明确的含义。

科技词汇多源于希腊语和拉丁语，是因为这两种语言作为英语的重要来源，是世界上成熟最早和最完备的语言中的两种，词汇不再发生词形、词义上的变化，具有稳定性。

2、句子方面多使用长句和被动语态，大量使用名词化结构（nominalization）和非限定动词。

另外，各种成份（如介词短语、形容词及其短语、副词、分词及从句等）作定语并后置，多使用It…that…结构句型、被动结构句型、as结构句型、分词短语结构句型和省略句结构句型等常用句型。

名词化结构有利于行文简洁、表达客观、内容确切，也可使所含信息量增大，尤其是科技英语强调存在的事实，而非个别行为。

不定式短语、-ing分词短语和-ed分词短语这三种非限定动词形式具有齐备的语法功能，可代替各种从句，这样既可缩短句子，行文简练，结构紧凑，又比较醒目。

3、形态方面科技英语在时态运用上有限，多用过去时和现在时。

尤其是多用一般现在时，以表述无时间性的科学定义、定理、公式、现象、过程等。

另外，科技英语多用逻辑性语法词（logical grammatical operators），如表示原因的如because (of)、due (owing) to、as (a result of)、caused by、for等，表示语气转折的如but、however、nevertheless、otherwise、yet 等，表示逻辑顺序的如so、therefore、thus、furthermore、moreover、in addition to等。

4、文体方面科技英语注重行文的连贯（coherence）、清晰（clarity）、流畅（fluency），避免行文晦涩、表露个人感情、过多运用修辞手法等。

Types of SustainabilityThe four types of sustainability include human, economic, social, and environmental. All four are required to maintain the entirety of life on Earth. Although interconnected, it is important to note the differences of each in terms of its nature and requirements.Types of Sustainability / HumanThe very basic need of human sustainability is good reproductive health and safe 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 children should have enough skills and knowledge such that they can sustain their own way of life. It is at that point that they become considered 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.Types of Sustainability / EconomicIn simple terms, economic sustainability is having a set amount of capital for a certain 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 that we must preserve all our resources as we consume them so that human beings in the 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.Types of Sustainability / SocialSocial 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 mistrust can take over. When that happens, societies and everything else that depends on them will be destroyed. Through proper maintenance of and adherence to laws, rules, and values that societies have developed for the common good, social sustainability can be achieved.Types of Sustainability / EnvironmentalEnvironmental sustainability is important because it involves natural resources that human beings need for economic or manufactured capital. Materials taken from nature are used for solutions that address human needs. If nature is depleted faster than it can regenerate, human beings will be left without raw materials.Furthermore, environmental sustainability also involves ensuring that waste emissions are at volumes that nature can handle. If not, all humans and other living things 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。
