Unit 1

01 Something in the American psyche loves new frontiers. We hanker after wide-open spaces; we like to explore; we like to make rules but refuse to follow them. But in this age it’s hard to find a place where you can go and be yourself without worrying about the neighbors.

美国人的内心深处具有一种酷爱探索新领域的气质。我们渴求宽敞的场地，我们喜欢探索，喜欢制定规章制度，却不愿去遵守。在当今时代，却很难找到一块空间，可以供你任意驰骋，又不必担心影响你的邻居。

02 There is such a place: cyberspace. Formerly a playground for computer fans, cyberspace now embraces every conceivable constituency: schoolchildren, flirtatious singles, Hungarian-Americans, accountants. Can they all get along? Or will our fear of kids surfing for dirty pictures behind their bedroom doors provoke a crackdown?

确实有这样一个空间，那就是信息空间。这里原本是计算机迷的游戏天地，但如今只要想像得到的各类人群应有尽有，包括少年儿童、轻佻的单身汉、美籍匈牙利人、会计等。问题是他们都能和睦相处吗?人们是否会因为害怕孩子们躲在卧室里看网上的淫秽图片而将它封杀?

03 The first order of business is to grasp what cyberspace is. It might help to leave behind metaphors of highways and frontiers and to think instead of real estate.2 Real estate, remember, is an intellectual, legal,

artificial environment constructed on top of land. Real estate recognizes the difference between parkland and shopping mall, between red-light zone3 and school district, between church, state and drugstore.

首先要解决的问题是，什么是信息空间。我们可以抛开高速公路、前沿新领域等比喻，把信息空间看作一个巨大的庄园。请记住，庄园是人们智慧的结晶，是合法的、人工营造的氛围，它建立在土地之上。在庄园里，公园和商业中心、红灯区与学校、教堂与杂货店都能区分开来。

04 In the same way, you could think of cyberspace as a giant and unbounded world of virtual real estate. Some property is privately owned and rented out; other property is common land; some places are suitable

for children, and others are best avoided by all citizens. Unfortunately,

it’s those places that are now capturing the popular imagi nation, places that offer bomb-making instructions, pornography, advice on how to steal credit cards. They make cyberspace sound like a nasty place. Good citizens jump to a conclusion: Better regulate it.

你可以用同样的方法把信息空间想像为一个巨大的、无边无际的虚拟庄园。其中有些房产为私人拥有并已租出，有些是公共场所；有的场所适合儿童出入，而有些地方人们最好避开。不幸的是，正是这些应该避开的地方使得人们心向神往。这些地方教唆你如何制造炸弹、为你提供淫秽材料、告诉你如何窃取信用卡。所有这些使信息空间听

起来像是一个十分肮脏的地方。正直的公民纷纷作出这样的结论：最好对它严加管理。

05 But before using regulations to counter indecency it is fundamental to interpret the nature of cyberspace. Cyberspace isn't a frontier where wicked people can grab unsuspecting children, nor is it a giant television system that can beam offensive messages at unwilling viewers. In this kind of real estate, users have to choose where they visit, what they see, what they do. It's optional. In other words, cyberspace is a voluntary destination—in reality, many destinations. You don't just get “onto the Net”; you have to go someplace in particular. That means that people can choose where to go and what to see. Yes, community standards should be enforced, but those standards should be set by cyberspace communities themselves, not by the courts or by politicians in Washington.

但是，在利用规章制度来反击下流之举之前，关键是从根本上理解信息空间的性质。恶棍并不能在信息空间抢走毫无提防之心的儿童；信息空间也不像一台巨大的电视机，向不情愿的观众播放令人作呕的节目。在信息空间这座庄园里，用户对他们所去之处、所见所闻、所做所为都要作出选择，一切都出于自愿。换句话说，信息空间是个出入自便的地方，实际上，信息空间里有很多可去之处。人们不能盲目上网，必须带着具体的目标上网。这意味着人们可以选择去哪个网址、看什么内容。不错，规章制度应该在群体内得以实施，但这些规章制

度必须由信息空间内各个群体自己来制定，而不是由法庭或华盛顿的政客们来制定。

06 What makes cyberspace so alluring is precisely the way in which it's different from shopping malls, television, highways and other terrestrial jurisdictions. But let's define the territory:

信息空间之所以具有如此大的诱惑力，正是因为它不同于商场、电视、公路或地球上的其他地方。那么，让我们来描述一下这个空间。

07 First, there are private e-mail conversations, similar to the conversations you have over the telephone. These are private and consensual and require no regulation at all.

首先，信息空间里人与人之间可以进行电子邮件交流。这种交流类似于电话交谈，都是私人之间的、两相情愿的谈话，不需要任何规章制度加以限制。

08 Second, there are information and entertainment services, where people can download anything fr om legal texts and lists of “great new restaurants” to game software or dirty pictures. These places are like bookstores, malls and movie houses— places where you go to buy something. The customer needs to request an item or sign up for a subscription; stuff (especially pornography) is not sent out to people who don’t ask for it. Some of these services are free or included as part of a broader service like CompuServe or America Online; others charge and may bill their customers directly.

其次，信息空间提供信息与娱乐服务。人们可以从中下载各种信息，从法律文件、“大型新饭店”名单，到游戏软件、下流图片，无奇不有。这里如同书店、商场和电影院，属购物区域。顾客必须通过索求或者登记来购物，物品(特别是淫秽之物)不会发送给那些没有索取的人。有些服务可以免费，或作为总服务费用的一部分计算，如“计算机服务”和“美国在线”就是如此。而有些服务要向顾客收费，而且可能会让顾客直接支付账单。

09 Third, there are “real” communities—groups of people who communicate among themselves. In real-estate terms, they're like bars or restaurants or bathhouses. Each active participant contributes to a general conversation, generally through posted messages. Other participants may simply listen or watch. Some services are supervised by a moderator; others are more like bulletin boards—anyone is free to post anything. Many of these services started out unmoderated but are now imposing rules to keep out unwanted advertising, extraneous discussions or increasingly rude participants.

第三，信息空间里还有真正意义上的群体，那就是在内部互相交流思想的人群。从庄园的角度来看，这些群体就像酒吧、饭店或公共浴室。每个活跃的人都积极参与谈话，谈话一般通过邮件方式进行；而有的人也许只充当旁观者或旁听者。有些活动由专人监督，有些则像公告牌，任何人可以任意在上面张贴。很多活动起初都无人监督，

但现在实行强制管理，用规章制度来扫除那些不受欢迎的广告、不相干的讨论或日渐粗鲁的成员。

10 Cyberspace communities evolve just the way terrestrial communities do: people with like-minded interests band together. Every cyberspace community has its own character. Overall, the communities on CompuServe tend to be more professional; those on America Online, affluent young singles; Prodigy, family-oriented. Then there are independents like Echo, a hip, downtown New York service, or Women's Wire, targeted to women who want to avoid the male culture prevalent elsewhere on the Net. On the Internet itself there are lots of passionate noncommercial discussion groups on topics ranging from Hungarian politics (Hungary Online) to copyright law.

信息空间里群体的演变过程正如陆地社会团体的演变过程，即情趣相投的人们聚在一起。信息空间里每一个团体都各具特色。总的来说，“计算机服务”上的团体一般由专业技术人员组成；“美国在线”上的团体一般为富有的独身者；“奇才”主要面向家庭。另外还有一些具有独到见解的服务机构，“共鸣”为其中之一，是纽约市中心一家时髦的服务机构。再如“妇女专线”，是专为女性开辟的，她们希望逃避网上其他地方盛行的男性文化。就因特网本身也有大量情绪激昂的讨论小组，都属非商业性质，讨论话题广泛，从匈牙利政治(匈牙利在线)到版权法，无所不及。

11 What's unique about cyberspace is that it allows communities of any size and kind to flourish; in cyberspace, communities are chosen by the users, not forced on them by accidents of geography. This freedom gives the rules that preside in cyberspace a moral authority that rules in terrestrial environments don't have.4 Most people are stuck in the country of their birth, but if you don't like the rules of a cyberspace community, you can just sign off. Love it or leave it. Likewise, if parents don’t like the rules of a given cyberspace community, they can restrict their children’s access to it.

信息空间的独特之处在于允许任何规模、任何种类的团体发展繁荣。在信息空间，用户自愿参加任何团体，而不是因为地理位置的巧合而被迫参加某个团体。这种自由赋予主宰信息空间的准则一种道义上的权威，这种权威是地球空间里的准则所没有的。多数人呆在自己出生的国土上动弹不得，而在信息空间，假若你不喜欢某一群体的准则，脱离这个群体即可。出入自由。同样，如果做父母的不喜欢某一群体的准则，便可以限制孩子，不让他们参与。

12 What’s likely to happen in cyberspace is the formatio n of new communities, free of the constraints that cause conflict on earth. Instead of a global village, which is a nice dream but impossible to manage, we’ll have invented another world of self-contained communities that cater to their own members’ inclinations without interfering with anyone else’s. The possibility of a real market-style evolution of governance is at hand.

In cyberspace, we’ll be able to test and evolve rules governing what needs to be governed — intellectual property, content and access control, rules about privacy and free speech. Some communities will allow anyone in; others will restrict access to members who qualify on one basis or another. Those communities that prove self-sustaining will prosper (and perhaps grow and split into subsets with

ever-more-particular interests and identities). Those that can’t survive —either because people lose interest or get scared off — will simply wither away.

在信息空间，可能会发生的情况是形成新的群体，新群体的形成不像在地球上那样受到限制，产生冲突。我们不是要建立一个梦寐以求、而又难以管理的全球村，而是要建立一个由各种独立的、不受外界影响的群体组成的世界，这些群体将投其成员所好，而又不干涉他人。一种真正的市场型管理模式很快成为可能。在信息空间，我们将能够检验并完善所需要的管理制度——知识产权制度、服务内容与使用权的控制制度、个人隐私权与自由言论制度等。有些群体允许任何人加入，而有些则只允许符合这样或那样条件的人加入。能够自持的群体会兴旺发展(或许也会因为志趣与身份日趋特殊，而发展成为几个分支)。有些群体或因为成员失去兴趣，或因为成员被吓跑而不能幸存下来，它们将渐渐萎缩消亡。

13 In the near future, explorers in cyberspace will need to get better at defining and identifying their communities. They will need to put in

place — and accept — their own local governments apart from terrestrial governments, just as the owners of expensive real estate often have their own security guards though they can call in the police to get rid of undesirable customers.

在不远的将来，信息空间的探索者应该更善于解释和辨别各群体的性质。除了现实中的政府之外，他们将有必要安置并接受自己的地方政府，就如同豪华庄园的业主一样，尽管可以叫警察来驱逐不受欢迎的顾客，但还是宁愿雇佣自己的保安。

14 Then what should be done about undesirable material in cyberspace? What to do, for instance, about pornography? The answer is labeling, besides banning, questionable material. It makes sense for cyberspace participants themselves to agree on a scheme for questionable items, so that people or automatic filters can avoid them. It's easy enough for software manufacturers to build an automatic filter that would prevent you or your child from ever seeing the undesired item on a menu. (It’s as if all the items were wrapped, with labels on the wrapper.) Someone who p osted pornographic material under the title “Kid-Fun” could be sued for mislabeling.

那么，该如何处置信息空间不受欢迎的材料呢?例如，淫秽材料该怎么办?答案除了禁止以外，就是在有问题的材料上贴上标签。信息空间的成员对有问题的内容应该达成共识，拿出一个解决方案来，使人们或自动过滤系统避开这些内容，这样可能会有助于解决问题。软

件制造商很容易建立一套自动过滤系统，使你和孩子们在菜单上见不到不想见到的内容。(就好像所有的内容都被包装了起来，并在包装纸上贴有标签。) 如果有人在色情材料上贴上“童趣”的标签，便可能会因错贴标签而被起诉。

15 Without a lot of fanfare, private enterprises and local groups are already producing a variety of labeling services, along with kid-oriented sites like Kidlink and Kids’ Space. People differ in their t astes and values and can find services on the Net that suit them in the same way they select books and magazines. Or they can wander freely if they prefer, making up their own itinerary.

一些私人组织和地方团体已经在不声不响地建立各种标签服务系统，并建立了适合儿童的网站，如“儿童连接”、“儿童空间”等。具有不同品味和抱有不同价值观念的人如同挑选书刊、杂志一样，可以从网上挑选出适合自己的服务机构。如果愿意，他们还可以在网上无拘无束地逍遥漫游，完成自己的旅程。

16 In the end, our society needs to grow up. Growing up means understanding that there are no perfect answers, no all-purpose solutions, no government-sanctioned safe havens. We haven’t cr eated a perfect society on earth, and we won't have one in cyberspace either. But at least we can have individual choice — and individual responsibility.

总之，我们的社会需要发展，要发展就意味着我们必须明白，世上没有完美无缺的答案，没有能够解决各种问题的妙方，没有政府认

可的安全避难所。我们不能在地球上建立一个十全十美的社会，同样也不能在信息空间营造一个这样的社会。但是至少我们可以有个人的选择——也有个人的责任。

1 While some studies have suggested that frequent use of cell phones causes increased risk of brain and mouth cancers, others have found no such links. But since cell phones are relatively new and brain cancers grow slowly, many experts are now recommending taking steps to reduce exposure. by bruce stutz 一些研究显示，经常使用手机会增加得脑部和口腔癌症的几率。有的研究却没发现两者之间有什么联系。但是，手机算是个新兴事物，而脑癌发展也缓慢，许多专家还是建议减少使用手机。 2 Does your cell phone increase your risk of brain cancer? Does it affect your skin or your sperm viability? Is it safe for pregnant women or children? Should you keep it in your bag, on your belt, in your pants or shirt pocket? Should you use a hands-free headset? Are present cell phone safety standards strict enough? 手机会增加得脑癌的几率吗？会不会影响皮肤或者精子活性？使用手机对孕妇或孩子安全吗？应该把手机放在哪，包里、衣服口袋，还是挂在腰带上？打电话的时候要用耳机吗？现在的手机安全标准够不够严？ 3 You don’t know? You’re not alone. 你不知道？这很正常。 4 With some 4 to 5 billion cell phones now in use worldwide and hundreds of studies seeking evidence of their health effects published in peer-reviewed journals over the last 10 years, there’s precious little scientific certainty over whether cell phones pose any danger to those using them. For nearly every study that reports an effect, another, just as carefully conducted, finds none. All of which leaves journalists, consumer advocates, regulatory agencies, politicians, industry spokespersons, and cell phone users able to choose and interpret the results they prefer, or ignore the ones they don’t. 如今，全世界共有40-50亿手机正在使用。过去十年里，成百上千的研究也在致力于寻找手机影响健康的证据，并在相关刊物上发表论文。但还没有确凿的证据能证明，使用手机损害健康。几乎没有研究发现手机对健康有不良影响。但这还是没影响到政治家、新闻记者、管理机构、产业发言人、消费者保护团体，还有消费者自己，选择他们喜好的结果去理解，忽略不喜欢的那些。 5 Do you, for instance, cite the studies that report adverse effects on sperm viability and motility, due to exposure to cell phone radiation or the studies that showed no —or mixed —results? 6 Do you cite the 2001 study that found increased incidence of uveal melanoma (a cancer of the eye) among frequent cell phone users, or the 2009 study by the same authors that, in reassessing their data, found no increase? 2001年的研究显示，常用手机的人患葡萄膜黑色素瘤（一种眼内癌症）几率会增大。2009年这些研究员又发表报告称，他们再分析当年的数据时，又不能确

Why We're Fat 1 So why is obesity happening? The obvious, clichéd-but-true answer is that we eat too much high-calorie food and don't burn it off with enough exercise. If only we had more willpower, the problem would go away. But it isn't that easy. 为什么会有肥胖症？一个明显、老生常谈但又真实的答案就是我们吃太多高热量食物并且没有进行足够的运动消耗它。要是我们的意志力更强大，这个问题便迎刃而解了。但是，问题并不是那么简单。 2 When warned about the dangers of overeating, we get briefly spooked and try to do better. Then we're offered a plateful of pancakes smothered in maple syrup, our appetite overpowers our reason, and before we know it, we're at it again. Just why is appetite such a powerful driver of behavior, and, more important, how can we tame it? 当我们被警告说吃得太多的时候，一时总会被吓倒并努力做好一些。然后一碟涂满槭糖浆的煎饼摆在面前，我们的食欲战胜了我们的理智，等到我们意识到它的时候，我们又重蹈覆辙了。到底为什么食欲具有如此强大的推动力？更重要的是，我们怎么才能够控制它？ 3 Within the past few years, science has linked our ravenous appetites to genes and hormones. Among the hormones that fuel these urges are ghrelin and leptin, known as the "hunger hormones." Ghrelin is produced mostly by cells in the stomach lining. Its job is to make you feel hungry by affecting the hypothalamus, which governs metabolism. Ghrelin levels rise in dieters who lose weight and then try to keep it off. It's almost as if their bodies are trying to regain the lost fat. This is one reason why it's hard to lose weight and maintain the loss. 近几年来，科学将我们迫不及待要吃的食欲跟基因和激素联系起来。激起这些强烈的欲望的激素有胃促生长素和消瘦素，也被称作“饥饿激素”。胃促生长素主要由胃保护层的细胞产生。它的职责是影响控制新陈代谢的下丘脑，让你感到饥饿。当节食者减肥并且努力维持减肥效果，他的胃促生长素水平就会升高。就像他们的身体要试图恢复失去的脂肪。这是为什么很难减肥并维持减肥效果的原因之一。 4 Leptin turns your appetite off and is made by fat cells. Low leptin levels increase your appetite and signal your body to store more fat. High leptin levels relay the opposite signal. Many obese people have developed a resistance to the appetite-suppressing effects of leptin and never feel satisfied, no matter how much they eat. Basically, your body uses these hormones to help you stay at your weight and keep you from losing fat —which is another reason why dieting can be so difficult. 消瘦素消除你的食欲，它来自脂肪细胞。低消瘦素水平增加你的食欲并通知你的身体储存更多的脂肪。高消瘦素水平传递相反的信号。很多肥胖的人已经形成了一种对消瘦素抑制食欲效应的抵抗，不管他们吃多少也从不感到满足。从根本上说，你的身体利用这些激素帮助你保持现在的体重，不让你的脂肪流走——这是节食如此之难的另外一个原因。

第一单元环境 大规模研究发现：地球的“健康”每况愈下有史以来对地球进行的最大规模的科学分析表明，地球上的许多生态系统都达不到标准。 由联合国主持的《千年生态系统评估综合报告》指出，由于不可持续的使用，地球上将近三分之二的用来维持生命的生态系统已经遭到破坏，其中包括干净的水源、纯净的空气，以及稳定的气候。 以上大部分的破坏都是人类在过去的半个世纪里造成的。据报告分析，随着人类对食物、淡水、木材、纤维以及燃料等资源的需求日趋激增，环境发生了极大的变化，引发了诸如滥伐森林、化学污染等问题。因此，该报告的作者警告说，照此下去，本已岌岌可危的生态环境将会在21世纪的上半叶急剧恶化。 这项历史性的研究由来自世界95个国家的政府部门以及民间组织的1,300多位科学家共同完成。四年来，他们考察了地球上许多生物的生长环境、物种以及将他们联系起来的生态体系。联合国环境规划署对该报告进行了编辑整理并于昨天在中国北京公布了研究结果。 在公布该报告的新闻发布会上，联合国秘书长科菲·安南指出：“只有了解环境及其运作过程，我们才能制定出必要的决策加以保护。”他还说，“只有珍惜所有宝贵的自然资源和人类资源，我们才有希望去建设一个可持续发展的未来。” 对社会经济的影响 该报告对自然界的大部分生物多样性持悲观态度，地球上可能有10%—30%的哺乳动物，鸟类以及两栖动物濒临灭绝。 这次大规模生态调查是根据安南的《千年发展目标》展开的，该发展目标是由联合国发起的，旨在2015年之前大幅度缓解饥饿与极度贫困等社会经济问题。 总部位于内罗毕的联合国环境规划署执行主席克劳斯·托普弗说：“从某些方面来说，《千年生态系统评估综合报告》让我们首次认识到生态系统服务功能的经济价值，并使我们对尊重和保护地球生命维护系统有了新的见解。” 目前由于人类社会对地球环境的开发利用，食物供应不断增加，然而增长的速度仍然太慢，难以完成联合国制定的在2015年前消除全球一半饥饿的目标。 报告还说，过度使用生态系统的负面影响还包括渔业的衰退，含有大量沉积物的河口周围近海“死亡区”的出现，水质的变化以及不可预测的区域性气候等。 此外，森林的滥伐和其他生态系统的巨大改变也加剧了诸如疟疾、霍乱等疾病的传播，并使已有传染病分化出新的类别。 根据该报告，水资源体系的变化会增加毁灭性洪灾的爆发频率和程度。在20世纪90年代，洪灾造成的死亡人数超过10万，损失约2,430亿美元。

核电与核辐射 1986 年4 月26 日，切尔诺贝利核电站的一个反应堆发生爆炸，将相当于400 颗广岛原子弹的放射性尘降物散布到整个北半球。在此之前，科学家对辐射对植物和野生动物的影响 几乎一无所知。这场灾难创造了一个活生生的实验室，尤其是在这个被称为禁区的1100 平方英里的区域。 1994 年，德州理工大学生物学教授罗纳德·切瑟和罗伯特·贝克是首批获准完全进入该区域的美国科学家之一。“我们抓了一群田鼠，它们看起来和野草一样健康。我们对此非 常着迷。”贝克回忆说。当Baker 和Chesser 对田鼠的DNA 进行测序时，他们没有发现 异常的突变率。他们还注意到狼、猞猁和其他曾经稀有的物种在这片区域游荡，仿佛这里 是原子野生动物保护区。2003 年由一组联合国机构建立的切尔诺贝利论坛发表了声明一份关于灾难20 周年的报告证实了这一观点，称“环境条件对该地区的生物群落产生了积极 影响”，将其转变为“一个独特的生物多样性保护区”。 五年前，贝克和切塞尔在这片区域搜寻田鼠。Mousseau 到切尔诺贝利去数鸟，发现了与之相矛盾的证据。穆萨乌是南卡罗莱纳大学的生物学教授，他的合作者安德斯·佩普·穆 勒现在是巴黎南方大学生态、系统学和进化实验室的研究主任。他们发现该地区家燕的数 量要少得多，而那些存活下来的家燕则遭受着寿命缩短、(雄性)生育能力下降、大脑变小、肿瘤、部分白化病(一种基因突变)以及白内障发病率更高的痛苦。在过去13 年发表的60 多篇论文中，Mousseau 和Moller 指出，暴露在低水平辐射下对该区域的整个生物圈产生 了负面影响，从微生物到哺乳动物，从昆虫到鸟类。 包括贝克在内的批评人士对穆萨和穆勒持批评态度。贝克在2006 年与切塞尔合著的《美国科学家》(American Scientist)文章中指出，该区域“实际上已成为一个保护区”，穆萨和穆勒的“令人难以置信的结论只得到了间接证据的支持”。 我们所知道的关于电离辐射对健康影响的几乎所有信息都来自于一项正在进行的对原子弹幸存者的研究，该研究被称为寿命研究，简称LSS。辐射暴露的安全标准基于LSS。然而，LSS 留下了关于低剂量辐射影响的大问题没有得到解答。大多数科学家都同意，没有所谓 的“安全”辐射剂量，无论剂量有多小。小剂量是我们最不了解的。LSS 并没有告诉我们多 少低于100 毫西弗(mSv)的剂量。例如，引起基因突变需要多少辐射，这些突变是可遗传 的吗?辐射诱发的疾病(如癌症)的机制和遗传生物标记物是什么? 三重危机2011年 3月福岛第一核电站创建另一个生活摩梭实验室和穆勒可以研究低 剂量的辐射,复制他们的切尔诺贝利核事故研究和允许他们“更高的信心,影响我们看到有关辐射,而不是其他因素,“摩梭说。福岛310平方英里的隔离区比切尔诺贝利小，但在其他方面 是一样的。这两个区域都包括被遗弃的农田、森林和城市地区，在这些地区，辐射水平在 短距离内变化数量级。而且几乎可以肯定，他们进入福岛的速度比科学家进入苏联控制的 切尔诺贝利的速度还要快。简而言之，福岛事件提供了一个解决争议的机会。 福岛核事故发生后的几个月里，穆萨乌和莫勒就开始在这座正在冒烟的核电站以西受污染的山林里清点鸟类数量，但他们无法进入这个区域，亲眼看看家燕的情况。最后，在2013 年6 月，穆萨乌是首批获准完全进入福岛禁区的科学家之一。 对辐射的敏感度在生物和同一物种的个体之间有很大的差异，这是重要的原因之一，不要从蝴蝶推断到家燕或从田鼠推断到人类。蝴蝶对辐射特别敏感，Mousseau 说。2012年8 月，在线期刊《科学报告》(Scientific Report)发表了一篇论文，研究福岛核泄漏对淡草蓝 蝶的影响。冲绳县琉球大学的生物学教授大木若二(Joji Otaki)透露，在这种不雅行为发生两个月后，在福岛附近采集的蝴蝶出现了翅膀、腿和眼睛畸形的情况。Mousseau 和Moller 对切尔诺贝利和福岛昆虫的调查显示，蝴蝶作为一个群体数量急剧下降。但御宅族

Unit 1 Genetically modified foods -- Feed the World? If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions -- and vocal green lobbies -- the idea seems against nature. 如果你想在某次晚宴上挑起一场激烈的争论，那就提出转基因食品的话题吧。对许多人来说，高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。特别是在有悠久的农业生产传统和主张环保的游说集团的国家里，转基因食品的主意似乎有悖自然。 In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic is out of the bottle. 事实上，转基因食品已经成为我们生活重要的一部分。根据农业部的统计，美国去年所种植玉米的1／3，大豆和棉花的一半以上都是生物技术的产物。今年，美国将种植6500多万英亩的转基因作物。基因妖怪已经从瓶子里跑出来了。 Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from -- and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations; the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks? 但是，显然还有一些非常现实的问题需要解决。就像任何一种要进入食物链的新食品一样，转基因食品必须经过严格的检验。在富裕的国家里，由于有大量丰富的食品可供选择，而且供应远远超过需求，所以关于生物技术的争论相对缓和一些。在迫切想要养活其迅速增长而又吃不饱的人口的发展中国家，问题比较简单，也更加紧迫：生物技术的好处是否大于风险呢? The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. And by 2050, the UN estimates, it will probably near 9 billion. Almost all that growth will occur in developing countries. At the same time, the world's available cultivable land per person is declining. Arable land has

稻草建筑材料在未来是否成为可能？ 露易丝·蒂克尔用稻草修房子并没有为《三只小猪》中的第一只带来任何好处，但是，如果巴斯大学的研究成果被建筑行业所接受的话，那么现代草砖将会成为未来的伟大设计。 说到一个草砖房子，你可能会联想到一个摇摇欲坠的窝棚，它漏水，发出吱吱的响声，随时都会垮塌在地，还带着类似农家的气息。但是当你踏入BaleHaus的时候，一个被修建于巴斯大学校园里，看起来原始的当代房屋，将会令你吃惊地出展现在你面前，并且，你会发现你无法找到任何一缕稻草。相反，你在一楼的走廊将会看到一个拥有两间卧室和一个浴室的倒置房子，和楼上一个通风的开放式的生活区。这就像是从斯堪的纳维亚半岛抵达了萨默赛特郡。 这些由石灰做底泥制成的，干燥稻草捆，原来都是被紧紧捆住并放置于一系列预制好的木质矩形框架结构的墙中的，它们像乐高拼装玩具一样被嵌入一个叫做ModCell 的嵌板中。 这些“草屋”存在的问题似乎并不在于它们并不实用，而是人们意识到它们有点非主流，并且并不是特别耐用。再加上，这样的草屋很难拿去获得抵押贷款。 巴斯大学BRE的建筑材料创新中心的主管Peter Walker 教授指出，稻草的好处在于：“它是便宜、易于广泛应用的良好绝缘体材料，它被用在房屋建筑上已经好几百年。” 作为整个世界的工业副产品——这些秸秆在谷物收获以后被留下——只要它们不分解，就仍然有效地吸收和固定大气中的碳。对于建筑行业来说，当前所依赖的材料是无论在生产还是运输上都具有极高的能耗和碳消耗的嵌入式混凝土和砖——因此，稻草可以为解决温室气体排放这一问题提供一个友好的解决方案。 无论这个草屋看上去有多时髦，多现代化还是多环保，你仍然想要知道它是否会在雷电交加的暴风雨中被淋得湿透或者是否会因你打翻的蜡烛，而被被嗖嗖的火焰烧的精光。Walker 教授和他的研究伙伴公布了他们的研究结果，Dr Katharine Beadle 花费了18个月的时间，通过一个详尽的危险因素清单去测试这个BaleHaus被腐蚀、烧毁、吹倒的可能，到目前为止，这个房子看来似乎是可靠的。 “你总想有点戏剧性的意外，但我们没让它发生。”Beadle 教授在团队将一块ModCell 的取样拿到测试实验室去，用一个温度不断上升并超过1000℃的火热的熔炉试图将其融为灰烬的那天笑着说。 “这是一个重现建筑火灾的标准化测试。”Walker 教授解释道。 “你需要至少30分钟的抵抗时间，这意味着你知道那个房子至少在半小时内会保持其结构的完整，这给了人们一个逃生的机会。” 在石灰底泥开始掉落之前，这花费了一个半小时直接接触火焰，Beadle说。“之后稻草开始燃烧，然而他们是如此的坚实以至于只是表面被烧焦而不是实体的瓦解。”
