Unit 9 科技类翻译赏析
Unit 9E-CMany biologists---and Dr. Szostak is one of them---think that life had a simpler early stage in which the varied tasks now carried out by DNA, RNA and proteins were all achieved by RNA alone. Even today, RNA molecules are not only messengers; they are also fetchers and carriers of amino acids, the building blocks of proteins. And they can catalyse reactions, as proteins do, too. In principle, then, RNA could act as both a cell’s genetic material and its self-assembly mechanism.If this idea is true, it should be possible to make a cell using just a membrane to hold things in place, some RNA, ingredients for more RNA, and an energy source. This comes in the form of an energy-rich molecule, ATP, which is what modern cells use to move energy from where it is generated to where it is used.包括索斯塔克博士在内的许多生物学家认为生命在早期阶段比较简单：现在由脱氧核糖核酸(DNA),核糖核酸（RNA)和蛋白质完成的繁多任务全都由RNA 单独完成。

2. Part Two Case Learning:
番茄时间管理法：适合你吗？ 如果你花很多时间去寻找生活小窍门，你就很可能听说过著名的番茄时间管 理法。番茄时间管理法在 20 世纪 80 年代由弗朗西斯科西里洛发明，是现在最受 欢迎的时间管理小窍门。但是这一方法并不适合所有人。有人是这一方法的忠实 拥护者，有人却对其结果颇多挑剔。 番茄时间管理法适合你吗？这是一种个人选择的事情。如果你对使用这一方 法的好处很好奇，本文将为你提供基本信息，你来决定是否值得一试。 基本概念 番茄时间管理法是一种时间管理哲学，其目的是为使用者提供最大化的关注 力以及创新的新鲜感，使得使用者能够以更小的脑力疲劳为代价，获得更快速的 任务完成。 过程很简单。对于每天的每一个项目，把时间分段，定时休息：工作 25 分 钟，休息 5 分钟。 每个长达 25 分钟的工作时段被称为一个“pomodoro”，意大利语，意为番 茄。弗朗西斯科西里洛使用一个形似番茄的厨房计时器作为自己的计时器，并以 此为这一方法命名。 四个“pomodoro”时间过去后（即工作了 100 分钟并休息了 15 分钟），你 可以休息 15 到 20 分钟。 每完成一个番茄时间，就画一个 X 作为记录，并且记下在每个 25 分钟时段 想要拖延或者去做另外一个任务的冲动的次数。 工作原理 有规律的休息保持大脑清醒、注意力集中。根据番茄官方网站的说法，该方 法使用简单，结果明显：“一两天就能看到工作或学习的变化。持续使用 7 到 20 天就可以真正掌握该方法。” 如果你的任务量大类多，番茄时间管理方法会让你坚持严格的计时，从而更 快速的完成项目。看着计时器旋转能促使你更快的完成当前任务，一个任务分散 到两到三个番茄时间能保证你不会感到很挫败。对工作活动的持续计时能保证你 对任务的责任心更高，将拖延的时间最小化。你会越来越“尊重番茄”，有助于 更好的应对工作。 拥护者说 苹果非官方微博的史蒂文桑德是这一方法的粉丝。他开发出大量的苹果兼容 的番茄工具。在使用番茄时间管理方法之前，他说：“有时候我不知道怎么处理 一天的时间，就是因为所有的工作都想去做，结果一个都没完成。” 另一个番茄时间管理方法的支持者是《华尔街日报》的苏榭伦伯格。她在尝 试了番茄时间管理方法以及其它类似的时间管理方法后说，这种方法缓解了时间 的流逝带给她的焦虑，并提高了工作效率；休息能让她回复精力，在对专栏内容 进行校对时，时间缩短了一半。 批评者说 除了这一方法的拥护者之外，也不乏批评者。克林米勒是雅虎的员工，也是 一位博主。在尝试了番茄时间管理方法之后发现了一些问题。

第九单元宇宙课文A宇宙大爆炸哈勃望远镜对宇宙深处的探索告诉了我们宇宙是如何起源的。
恒久以来，人们常常问到的一个问题就是：宇宙是如何创造的？许多人认为宇宙既没有开始，也没有结束，宇宙是真正无限的。
然而自从宇宙大爆炸理论创立以来，宇宙就不再被认为是无限的了。
宇宙被冠以有限现象的特性，有了历史也有了起源。
大约150亿年前，宇宙的膨胀由一场巨大的爆炸伊始。
这一爆炸就是众所周知的“宇宙大爆炸”。
在爆炸发生时，宇宙空间中的所有物质和能量都存在于一个点。
至于在此之前还存在过什么则是完全未知的，是纯粹的猜想。
这一爆炸的发生并不是常规性的，爆炸使得胚胎时期的宇宙中充满了急速离散的粒子。
宇宙大爆炸不像炸弹爆炸那样，所有的爆炸碎片都向外飞出，它实际上是一个空间在其内部的爆炸。
当时星系并非成团地聚在一起，大爆炸为宇宙的诞生奠定了基础。
大爆炸理论的起源应归功于埃德温·哈勃。
哈勃观测到宇宙是在不断扩大的。
他发现，星系的运动速度与其距离是成正比的。
因此，距离我们两倍远的星系，移动速度也是我们的两倍。
另一个结论是，宇宙是向四面八方膨胀的。
这一观测意味着对于所有星系来说，他们从一开始相同的位置移动到现在各自的位置所用的时间都是一样的。
正如宇宙大爆炸为宇宙奠定了基础一样，哈勃的观测也为宇宙大爆炸理论奠定了基础。
自宇宙大爆炸以来，宇宙一直在不断扩大，而且星系团之间的距离也越来越远。
这种星系互相远离的现象被称为红移。
当光从遥远的星系接近地球时，地球和星系之间的空间也在增加，从而导致波长的拉伸。
人们除了对星系从一个单一的点向外扩散所产生的速度有所了解，宇宙大爆炸还有进一步的证据。
1964年，天文学家阿诺·彭齐亚斯和罗伯特·威尔逊在尝试探测外层空间微波的过程中，无意中发现了一个地球以外的噪音源。
噪音似乎并不只是来自于一个位置，相反，它同时来自四面八方。
很明显，他们所听到的是来自大爆炸所遗留的宇宙最远处的辐射。
科技英语unit9原文
Urbanisation means an increase in the proportion of people living in urban areas compared to rural areas. An urban area is a built-up area（建筑区域）such as a town or city.A rural area is an area of countryside.城市化是指生活在城市地区的人相比农村地区的人占总人数的比例在增加。
一个城市地区是指一个建筑区域，比如城镇或城市。
农村地区是指乡村地区。
As a country industrialises, the number of people living in urban areas tends to increase. The UK and many other MEDCs urbanised（城市化）during the 18th and 19th centuries. People migrated from rural areas (due to the mechanisation in farming) to urban areas where there was employment in the new factories. The area of cities known as the inner city developed during this time as rows of terraced housing （露台房）were built for workers.作为一个工业化进程的国家，生活在城市地区的人数有增加的趋势。
英国和其他许多经济较发达国家城市化在第十八和第十九世纪。
人们从农村迁移出来（由于机械化耕作）到了城市地区可以就业的新工厂。
这些地区被称为内城，发达国家还在这里为工人建造一行行梯型的露台住房。

Unit 9 TechnologyA LIFE ON THE GOWang Mei puts her hand into her pocket, takes out her red cellphone and presses the talk key. "Hi, mum! I'm on the bus. I should be home in about ten minutes." Wang Mei is one of many Chinese teenagers who live life "on the go" and use cellphones.Cellphones, or mobile phones, make it possible for us to talk to anyone from anywhere. Words and images are being sent throughout the world. Modern cellphones are more than just phones — they are being used as cameras and radios, and to send e-mail or surf the Internet. New functions are being added to the phones. The latest cellphones have features such as games, music and an electronic calendar that will remind you about appointments and important dates.Cellphones have changed our behaviour and how we communicate. They are being used everywhere —sometimes where they shouldn't. One headmaster says that phones are not allowed in the classroom. "If a phone starts ringing in the classroom, teachers and students are disturbed and cannot work." The students obey the rules and agree not to use their phones in the classroom. "I don't dare to use the phone in school, because they will take it away from me," says John Hill, a student in London. John got his phone for his birthday, but his parents don't let him use it in school. Some parents worry that their children will spend too much time and money on phone calls.Why are cellphones so popular, especially among teenagers? The answer seems to be that we have a need to stay in touch with friends and family no matter where we are or what we are doing. Having a cellphone also makes us feel safer, since we can call for help in case of an emergency. Of course, to many teenagers the cellphone is not only a useful tool but also a way to have fun and be cool.Wang Mei calls her best friend Xiao Li at least once a day to see how she is doing and what is going on. She says that her cellphone helps her do whatever she wants to do and still stay in touch with her parents and friends. "I think it's the most useful invention ever," Wang Mei says as she is dialling the number to Xiao Li again to ask her what she will be wearing to school tomorrow.BIt is the year 2374 and the machines have taken over. The earth is ruled by a great computer named Q12 that uses robots to make people work for it. It is not a happy world. The few surviving human beings are being used in the way that we use machines today: they have to make electricity for the machines, repair them when they break down, and do everything Q12 tells them to. Once, the earth was a beautiful blue planet where people lived happily among trees and animals. Now, the world is dark and dirty, with no room for happiness and fun.But there is still hope. The human beings have been able to keep a small, secret school open since the machines took over. In this school, the students still learn about all the wonders of the world — science, art, history, culture — and they are still allowed to dream about a better future. The leader of the humans has decided that it is time to do something to stop Q12, bring the machines and people back together, and make the world beautiful again. A group of experts were asked to solve the problem, but they failed. Now, the leader has asked a group of students to do what they can to save the earth.Q12 cannot be defeated by force. It is too strong and no one believes that fighting a war can solve the problem. Instead, the students have decided to come up with a peaceful solution. They will try to teach Q12 about love and friendship. If they succeed, they believe that humans and machines can live together like friends in the future.。

Unit 9 Science and Technology新编大学英语第二版第四册课文翻译
Unit 9 Science and TechnologyToo Fast?People who were born just before World War I remember waving at automobiles as they passed. Seeing a car was like watching a parade—exciting and out of the ordinary. The airplane—it was spelled "aeroplane" then—was another new invention. Refrigerators were "iceboxes," and a man delivered the ice for the box in the summer and the coal for the stove in the winter. Now, the iceman, like the blacksmith, survives only in literature.Today, change comes so fast that working people can become obsolete because their occupations vanish in the middle of their lives. Knowledge, and thus the rate of change, increases geometrically. Every idea gives birth to a dozen new ones, and each of them has a dozen children. The people of the pre-World War I generation had hardly assimilated the inventions of that era before they were attacked by a new batch of even more sophisticated inventions. The Atomic Age dawned in 1945, August 6 to be exact, and then, before we could catch our breath, the Space Age arrived.Change was not always this rapid. Certain important inventions, like the telephone, the airplane, the automobile, and the radio, had been invented by 1914, but the effects of these inventions upon the lives of ordinary citizens were not felt until many years later. We now have the technology to develop machines before people are ready to use them. For example, we have the technology to enable people to pay their bills by phone—but even people with phones resist. The change is too much too fast. People don't want to talk to machines, especially if the machines talk back to them.It is certain that technology, especially computer technology, will rule our lives to a greater and greater degree. This situation will not necessarily prove positive or negative in effect. Many people would be more comfortable if change came more slowly, but on the other hand, there are many for whom every innovation is like a new toy. They can't wait for the next invention to be available. When scientists talk about the remarkably adaptable nature of people, they probably have these people in mind.But there is a limit to everyone's ability to adapt. What will happen to us when change comes so rapidly that we can no longer adjust to it? These same scientists who talk about our adaptable nature also tell us that change is to some degree emotionally painful to everyone. What then, will happen to us when change comes so rapidly that we can no longer stand the pain, and we refuse to change?We have read a lot about scientific and technological change, but that is only part of the picture of modern life. There is often a great lag between scientific discovery andcultural acceptance. For example, Charles Darwin's theory of evolution, proposed over one hundred years ago and accepted by all serious scholars for generations, is still rejected by large segments of society. These segments see science as contradicting a higher religious authority. They see science as questioning and destroying their beliefs and culture.The problem is not easily solved because it is in the nature of science to question, and it is in the nature of human beings not to want to question the things they believe in. Science is not merely a field of study like chemistry or physics or biology. Science is a method of looking at the world, a method that requires an open mind, objectivity, and proof based upon observation or experimentation. It is a method that ignores religion, race, nationality, economics, morality, and ethics. It pays attention only to the results of research. The scientific method has shown us endless marvels and wonders, but methods can't provide all the answers. Science cannot tell us whether or not to drop a bomb: That is a moral or political question. Science only tells us how to make one.As we have already said, technological innovations are being made at faster and faster rates. The future will be even more revolutionary than the past. Will we, as a species, survive the revolutions that we have begun? There is plenty of evidence to think that we will. Our species has enormous potential that we have just begun to use. For example, we have only begun to control the environment. One day technology will make every desert bloom. It's simple, really. To do so, all we need to do is lower the cost of converting sea water into fresh water. Then, when the deserts bloom, will they provide enough food for our growing numbers? Most likely, they will. We have only just begun to discover the possibilities of highly intensive desert agriculture. We already have the technology to increase production ten times and to use one-twentieth of the water we needed before.We know how to make agricultural miracles. What we need are the time and money to make the technology available to everyone.In the nineteenth century, people believed in progress. They believed that science would lead them to a new era of endless prosperity and happiness. Well, it didn't work out that way. Two disastrous world wars convinced people of that. Yet, in our disappointment and in our fears that science was a monster that would one day destroy us, we forgot that science was not the monster; we were the monster. Science was merely a servant, and like fire, a good servant when treated properly.Despite all the problems of the modern world, however, most people would not choose to live in any of the less scientific ages that have preceded ours. If—and this is abig if—we don't destroy ourselves in war, the future can only be better. Each year will bring a more bewildering array of scientific advances: diseases cured, space conquered, transportation and communication revolutionized, agriculture and industry completely transformed, etc. To some, the future sounds exciting; to others, frightening. But one thing is sure—it won't be boring.太快了？1 在第一次世界大战前夕出生的人仍然记得看到身边经过的汽车就挥手的情景。

Unit10: Food Technology: Not Only DeliciousReading AReading BReading C6 Once the system was defined, the data inventory was collected — that is, data was gathered about the resource use, energy consumption, emissions and products resulting from each activity in the production chain. All in- and out-flows were then calculated on the basis of a unit of the product called the functional unit (here, 1 kg of tomato salsa consumed at the household). Regarding data on production of packaging materials, emissions from transport, fuel production/combustion and electricity generation data from the Ecoinvent Centre were used. For data on cultivation and dicing of onions and tomatoes, as well as the production of tomato puree, previous LCA studies were sourced. Regarding data on production of conventional salsa (input of raw materials, energy use and wastage at the plant), data from an industrial producer in Sweden were used. Data on HPP and packaging were provided by researchers at the Agrotechnology & Food Innovation, part of Wageningen University& Research Centre, the Netherlands, and the Universityof Naples, also part of the NovelQ project.7 The first result of an LCA is a matrix of inventory results, where the calculated values for each phase of the life cycle as well as the total values are presented for a number of categories of substances, resources from the ground, resources from water, emissions to air, emissions to water and products. To simplify this table and get an idea of what kind of environmental impact the emissions cause, impact assessment methods are used that weigh together all emissions causing global warming potential, acidification, eutrophication, etc. (Figure 2).8 Figure 3 shows the use of primary energy for the different salsa products; the energy use was significantly higher for the conventional salsa product, mainly due to the use of energy for heat treatment at the salsa factory, but also due to the production of glass and metal packaging. The energy use at the salsa factory was quite insignificant for HPP and HPP/ sterilization. More energy was neededfor retailer storage of the heat-treated and HP-sterilized products; even though the storage was not refrigerated as it was for the fresh and HP-processed salsa products, but because the former are assumed to be stored for 12 months, energy use was still higher for those products.9 Transport was quite significant in all four product life cycles (“transport” included all the transport of packaging materials, raw materials and the product up to retailing). Approximately 50% of the energy use for transport was due to the use of lorries (trucks) and the other 50% resulted from barge transport. It is also important to note that the consumer transport accounted for a large part of the overall energy use; the conventional salsa had a slightly higher contribution than the others because its packaging was heavier, and we allocated the burden from consumer transport based on mass.10 Contribution to global warming potential is shown in Figure 4; here, it is clear that the fresh salsa had the highest contribution. Slightly more tomatoes are needed to produce the fresh salsa products, resultingin these products having a slightly higher contribution from cultivation compared to the heat-treated product. In terms of packaging, overall, the fresh product with the polypropylene packaging had the highest contribution to global warming potential. We have assumed the plastic packaging would be sent to municipal waste incineration after use, so this would generate carbon dioxide emissions. As the polypropylene packaging was heavier than the pouch used for the two HP products, the polypropylene packaging had a higher contribution. Transport —both goods transport and consumer transport —contributed significantly to this impact category.11 The study results indicate that HP-processed product has environmental benefits compared to conventional, heat-treated product in terms of the decreased energy required for processing. However, the largest difference in environmental impact between the products is not linked to this energy decrease, but rather to the type of packaging that is used and to the composition of the products.

Urbanisation means an increase in the proportion of people living in urban areas compared to rural areas. An urban area is a built-up area（建筑区域）such as a town or city.A rural area is an area of countryside.城市化是指生活在城市地区的人相比农村地区的人占总人数的比例在增加。
一个城市地区是指一个建筑区域，比如城镇或城市。
农村地区是指乡村地区。
As a country industrialises, the number of people living in urban areas tends to increase. The UK and many other MEDCs urbanised（城市化）during the 18th and 19th centuries. People migrated from rural areas (due to the mechanisation in farming) to urban areas where there was employment in the new factories. The area of cities known as the inner city developed during this time as rows of terraced housing （露台房）were built for workers.作为一个工业化进程的国家，生活在城市地区的人数有增加的趋势。
英国和其他许多经济较发达国家城市化在第十八和第十九世纪。
人们从农村迁移出来（由于机械化耕作）到了城市地区可以就业的新工厂。
这些地区被称为内城，发达国家还在这里为工人建造一行行梯型的露台住房。
Today the UK is a mostly urban society, with 90% of the population living in towns or cities.On a global scale, urbanisation is taking place rapidly, particularly in LEDCs今天，英国是一个主要的城市社会，有90%的人口居住在城镇或城市。
在全球范围内，城市化正在发生迅速，特别是在经济欠发达国家Although the UK is an urban society, more and more people are choosing to live on the edge of urban areas - with many relocating to the countryside. This is called counter-urbanisation.英国虽然是一个城市化的社会，但是越来越多的人选择生活在边缘的城市地区，甚至搬迁到农村居住。
这就是所谓的反城市化。
Problems of urbanisation in the CBD – traffic congestion Traffic jam on the M6 motorway商务中心区的城市化问题–交通拥塞6号高速公路上的交通堵塞As more people move to the edge of towns and cities, traffic congestion may get worse. Many people will drive their cars into the city centre to get to work.随着越来越多的人移到城镇和城市的边缘地区，交通拥堵可能会变得更糟。
很多人会自己开车到市中心去工作。
It is compounded by people being brought into city on large roads or motorways. These roads then link up with smaller, older, narrower roads in the city centre. This causes a bottleneck and congestion.它（交通拥堵）是由大量经过城市道路或高速公路进入市区的人们加重的，这些道路与在城市中心的更小，更年老，更窄的道路联系在一起。
这就导致交通瓶颈和拥塞。
Some cities have tried to manage this problem byintroducing traffic management schemes. These schemes may include:一些城市试图通过交通管理方案解决这个问题。
这些方案大概包括∙1.Park and ride schemes.∙ 2.Cycle lanes.∙ 3.Congestion charging schemes, such as those in Durham and London.∙ 4.Car-pooling, as used in the USA, to encourage people to share cars.∙ 5.Low Emission Zones, as in London.1停车换乘方案。
•2车道。
•3拥挤收费方案，如在达拉谟和伦敦。
•4.拼车，正如在美国，鼓励人们分享汽车。
•5低排放区，如在伦敦。
Local councils have also tried to make the roads in urban areas safer by introducing traffic calming, pedestrianzones, vehicle-exclusion zones and permit-onlyparking schemes.地方议会也试图通过交通提醒物，步行区域，无车辆区和唯一允许停车计划让市区交通更加安全。
Problems of urbanisation in the urban rural fringe – housing demand在城乡结合部的城市化问题–住房需求'For Sale' signs outside a houseSocial and demographic changes are leading to a greater demand for housing. People are living longer, and choosing to marry later, and in recent years there has been a rise in the number of single-parent families. Added to this, the UK is experiencing immigration from other countries, eg from Poland which has recently joined the EU. The result is an ever-larger number of smaller households, all requiring accommodation.在房子外面的“出售”标志社会和人口结构的变化正导致更大的住房需求。
人们的寿命延长，并且结婚更迟，并在最近几年已经有越来越多的单亲家庭。
此外，英国正经历来自其它国家的移民，如由波兰最近已加入欧盟。
其结果是越来越多的较小的家庭，而他们都需要住宿。
However, building new, affordable homes in urban areas is difficult. Land values are very high and land is in short supply:Some developers are building on sites that have been built on before in the UK's inner cities.These are called brownfield sites. This has happened in many of the UK’s inner cities.然而，在城市地区建立新的，能负担得起的住房是困难的。
土地价格高，土地本身紧缺：•一些开发商在网站上建设住房比在英国内城市建得还早。
这些被称为布朗菲尔德网站。
这出现在许多英国内都市。
Other developers are building homes on the edge of the city on greenfield sites in the urban rural fringe. Land here is cheaper but greenfield development can cause conflict with local people and create environmental problems.其他开发商在城市的边缘建造住房城市绿地中的绿化点，这里土地便宜但绿地的发展可引起当地居民的冲突和造成的环境问题。
Sustainable citiesMany people are working towards trying to make cities more sustainable. A sustainable city offers a good quality of life to current residents but d oesn't reduce the opportunities for future residents to enjoy.可持续城市很多人都正在努力想让城市可持续发展。
可持续的城市，为目前的居民提供了一个良好的生活质量却又不减少未来居民享受的机会。
Key features of a sustainable city∙ 1.Resources and services in the city are accessible to all.∙ 2.Public transport is seen as a viable alternative to cars.∙ 3.Public transport is safe and reliable.∙ 4.Walking and cycling is safe.∙ 5.Areas of open space are safe, accessible and enjoyable.∙ 6.Wherever possible, renewable resources are used instead of non-renewable resources.∙ 7.Waste is seen as a resource and is recycled wherever possible.∙ 8.New homes are energy efficient.∙ 9.There is access to affordable housing.∙ munity links are strong and communities work together to deal with issues such as crime and security.∙ 11.Cultural and social amenities are accessible to all.∙ 12.Inward investment is made to the CBD.可持续城市的主要特点：•1。
