Lecture 11 Four lessons about climate crisis
I’m really scared. I don’t think we’re gonna make it. Probably by now most of you have seen Al Gore’s amazing talk. Shortly after I saw that, we had some friends over for dinner with the family. The conversation turned to global warming, and everybody agreed, there’s a real problem. We’ve got a climate crisis. So, we went around the table to talk about what we should do. The conversation came to my 15-year-old daughter, Mary. She said, “I agree with everything that’s been said. I’m scared and I’m angry.” And then she turned to me and said, “Dad, your generation created this problem, you’d better fix it.” Wow. All the conversation stopped. All the eyes turned to me. (Laughter) I didn’t know what to say. Kleiner’s second law is, “There is a time when panic is the appropriate response.” (Laughter) And we’ve reached that time. We cannot afford to underest imate this problem. If we face irreversible and catastrophic consequences, we must act, and we must act decisively. I’ve got to tell you, for me, everything changed that evening.
And so, my partners and I, we set off on this mission to learn more, to try to do much more. So, we mobilized. We got on airplanes. We went to Brazil. We went to China and to India, to Bentonville, Arkansas, and to Washington, D.C. and to Sacramento. And so, what I’d like to do now is to tell you about what we’ve learned in those
journeys. Because the more we learned, the more concerned we grew. You know, my partners at Kleiner and I were compulsive networkers, and so when we see a big problem or an opportunity like avian flu or personalized medicine, we just get together the smartest people we know. For this climate crisis, we assembled a network, really, of superstars, from policy activists to scientists and entrepreneurs and business leaders. Fifty or so of them. And so, I want to tell you about what we’ve learned in doing that and four lessons I’ve learned in the last year.
The first lesson is that companies are really powerful, and that matters a lot. This is a story about how Wal-Mart went green, and what that means. Two years ago, the CEO, Lee Scott, believed that green is the next big thing, and so Wal-Mart made going green a top priority. They committed that they’re gonna take their existing stores and reduce their energy consumption by 20 percent, and their new stores by 30 percent, and do all that in seven years. The three biggest uses of energy in a store are heating and air conditioning, then lighting, and then refrigeration. So, look what they did. They painted the roofs of all their stores white. They put smart skylights through their stores so they could harvest the daylight and reduce the lighting demands. And third, they put the refrigerated goods behind closed doors with LED lighting. I mean, why would you try to refrigerate a
whole store? These are really simple, smart solutions based on existing technology.
Why does Wal-Mart matter? Well, it’s massive. They’re the largest private employer in America. They’re the largest private user of electricity. They have the second-largest vehicle fleet on the road. And they have one of the world’s most amazing supply chains, 60,000 suppliers. If Wal-Mart were a country, it would be the sixth-largest trading partner with China. And maybe most important, they have a big effect on other companies.
When Wal-Mart declares it’s gonna go green and be profitable, it has a powerful impact on other great institutions. So, I tell you this: When Wal-Mart achieves 20 percent energy reductions, that’s gonna be a very big deal. But I’m afraid it’s not enough. We need Wal-Mart and every other company to do the same.
The second thing that we learned is that individuals matter, and they matter enormously. I’ve got another Wal-Mart story for you, OK? Wal-Mart has over 125 million U.S. customers. That’s a third of the U.S. population. Sixty-five million compact fluorescent light bulbs were sold last year.
And Wal-Mart has committed they’re gonna sell another 100 million light bulbs in the coming year. But it’s not easy. Consumers don’t really like these light bulbs. The light’s kind of funny, they
won’t dim, takes a while for them to start up. But the p ay-off is really enormous. A hundred million compact fluorescent light bulb means that we’ll save 600 million dollars in energy bills, and 20 million tons of CO2 every year, year in and year out. It does seem really hard to get consumers to do the right thing. It is stupid that we use two tons of steel, glass, and plastic to haul our sorry selves to the shopping mall. It’s stupid that we put water in plastic bottles in Fiji and ship it here. (Laughter)
It’s hard to change consumer behavior, because consumers don’t know how much this stuff costs. Do you know? Do you know how much CO2 you generated to drive here or fly here? I don’t know, and I should. Those of us who care about all this would act better if we knew what the real costs were. But as long as we pretend that CO2 is free, as long as these uses are nearly invisible, how can we expect change? I’m really afraid, because I think the kinds of changes we can reasonably expect from individuals are gonna be clearly not enough.
The third lesson we learned is that policy matters. It really matters. In fact, policy is paramount. I’ve got a behind-the-scenes story for you about that green tech network I described. At the end of our first meeting, we got together to talk about what the action items would be, how we’d follow up. And Bob Epstein raised a hand. He
stood up. Y ou know, Bob’s that Berkeley techie type who started Sybase. Well, Bob said the most important thing we could do right now is to make it clear in Sacramento, California that we need a market-base d system of mandates that’s gonna cap and reduce greenhouse gases in California. It’s necessary and, just as important; it’s good for the California economy.
So, eight of us went to Sacramento in August and we met with the seven undecided legislators and we lobbied for AB32. Y ou know what? Six of those seven voted yes in favor of the bill, so it passed, and it passed by a vote of 47 to 32. (Applause) Please don’t. Thank you. I think it’s the most important legislation of 2006. Why? Because California was the first state in this country to mandate 25 percent reduction of greenhouse gases by 2020. And the result of that is, we’re gonna generate 83,000 new jobs, 4 billion dollars a year in annual income, and reduce the CO2 emissions by 174 million tons a year. California’s only 7 percent of U.S. CO2 emissions. It’s only a percent and a half of the country’s CO2 emissions. It’s a great start, but I’ve got to tell you—where I started—I’m really afraid. In fact, I’m certain California’s not enough.
Here’s a story a bout national policy that we could all learn from. You know Tom Friedman says, “If you don’t go, you don’t know?” Well, we went to Brazil to meet Dr. Hussain Goldemberg. He’s the
father of the ethanol revolution. He told us that Brazil’s government mandated that every gasoline station in the country would carry ethanol. And they mandated that their new vehicles would be
flex-fuel compatible, right? They’d run ethanol or ordinary gasoline. And so, here’s what’s happened in Brazil. They now have 29,000 ethanol pumps—this versus 700 in the U.S., and a paltry two in California—and in three years their new car fleet has gone from 4 percent to 85 percent flex-fuel. Compare that to the U.S., 5 percent are flex-fuel. And you know what? Most consumers who have them
d on’t even know it. So, what’s happened in Brazil is, they’v
e replaced
40 percent of the gasoline consumed by their automotive fleet with ethanol. That’s 59 billion dollars since 1975 that they didn’t ship to the Middle East. It’s created a million jobs ins ide that country, and it’s saved 32 million tons of CO2. It’s really substantial. That’s 10 percent of the CO2 emissions across their entire country. But Brazil’s only 1.3 percent of the world’s CO2 emission. So, Brazil’s ethanol miracle I’m really afraid is not enough. In fact, I’m afraid all of the best policies we have are not gonna be enough.
The fourth and final lesson we’ve learned is about the potential of radical innovation. So, I want to tell you about a tragic problem and a breakthrough technology. Every year a million and a half people die of a completely preventable disease. That’s malaria. Six
thousand people a day. All for want of two dollars worth of medications that we can buy at the corner drugstore. Well, two dollars, two dollars is too much for Africa. So, a team of Berkeley researchers with 15 million dollars from the Gates Foundation is engineering, designing a radical new way to make the key ingredient, called artemisinin, and they’re gonna make that drug 10 times cheaper. And in doing s o, they’ll save a million lives—at least a million lives, a year. A million lives. Their breakthrough technology is synthetic biology. This leverages millions of years of evolution by redesigning bugs to make really useful products. Now, what you do is, you get inside the microbe, you change its metabolic pathways, and you end up with a living chemical factory.
Now, you may ask, John, what has this got to go with green and with climate crisis? Well, I’ll tell you a lot. They’ve now formed a company called Amyris, and this technology that they’re using can be used to make better biofuels. Don’t let me skip over that. Better biofuels are a really big deal. That means we can precisely engineer the molecules in the fuel chain and optimize them along the way. So, if all goes well, they’re gonna have designer bugs in warm vats that are eating and digesting sugars to excrete better biofuels. I guess that’s better living through bugs. Alan Kay is famous for saying the best way to predict the future is to invent it. And, of course, at
Kleiner we, kind of, apologize and say the second best way is to finance it. And that’s why we’re investing 200 million dollars in a wide range of really disruptive new technologies for innovation in green technologies. And we’re encoura ging others to do it as well. We’re talking a lot about this.
In 2005, there were 600 million dollars invested in new technologies of the sort you see here. It doubled in 2006 to 1.2 billion dollars. But I’m really afraid we need much, much more. For
refer ence, fact one: Exxon’s revenues in 2005 were a billion dollars a day. Do you know, they only invested 0.2 percent of revenues in R&D? Second fact: the President’s new budget for renewable energy is barely a billion dollars in total, less than one day of E xxon’s revenues. Third fact: I bet you didn’t know that there’s enough energy in hot rocks under the country to supply America’s energy needs for the next thousand years. And the Federal budget calls for a measly 20 million dollars of R&D in geothermal energy. It is almost criminal that we are not investing more in energy research in this country.
And I am really afraid that it’s absolutely not enough.
So, in a year’s worth of learning we found a bunch of surprises. Who would have thought that a mass retailer could make money by going green? Who would have thought that a database entrepreneur could transform California with legislation? Who would have
thought that the ethanol biofuel miracle would come from a developing country in South America? And who would have thought that scientists trying to cure malaria could come up with breakthroughs in biofuels? And who would have thought that all that is not enough? Not enough to stabilize the climate. Not enough to keep the ice in Greenland from crashing into the ocean. The scientists tell us—and they’re only guessing—that we’ve got to reduce greenhouse gas emissions by one half, and do it as fast as possible. Now, we may have the political will to do this in the U.S., but I’ve got to tell you, we’ve got only one atmosphere, and so somehow we’re gonna have to find the political will to do this all around the world.
Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you wha t. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Well, I’ll tell you what. Green technologies—going green—is bigger than the Internet. It could be the biggest economic opportunity of the 21st century. Moreover, if we succeed it’s gonna be the most important transformation for life on the planet since, as Bill Joy says, we went from methane to oxygen in the atmosphere. Now, here’s the hard
question, if the trajectory of all the world’s companies and individuals and policies and innovation is not gonna to be enough, what are we gonna do? I don’t know. Everyone here cares about changing the world and has made a difference in that one way or another.
So, our call to action—my call to you—is for you to make going green your next big thing, your gig. What can you do? You can personally get carbon neutral. Go to https://www.doczj.com/doc/5818917072.html, or https://www.doczj.com/doc/5818917072.html, and buy carbon credits. You could join other leaders in mandating, lobbying for mandated cap and trade in U.S. greenhouse gas reductions. There’s six bills right now in Congress. Le t’s get one of them passed.
And the most important thing you can do, I think, is to use your personal power and your Rolodex to lead your business, your institution, in going green. Do it like Wal-Mart, get it to go green for its customers and its suppliers and for itself. Really think outside the box. Can you imagine what it would be like if Amazon or eBay or Google or Microsoft or Apple really went green and you caused that to happen? It could be bigger than Wal-Mart. I can’t wait to see what we TEDsters do about this crisis. And I really, really hope that we multiply all of our energy, all of our talent, and all of our influence to solve this problem. Because if we do, I can look forward to the
conversation I’m gonna have with my daughter in 20 years.
U8 A 1 在过去的30年里，作为一个专业的大提琴演奏家，我花了相当于整整20年时间在路上执行和学习音乐传统和文化。我的旅行使我相信在我们的全球化的世界中，文化传统来自于一个身份、社会稳定和富有同情心的互动的基本框架。 2 世界在快速改变，正如我们一定会创造不稳定的文化，让人质疑他们的地方。全球化使我们服从于别人的规则，这往往会威胁到个人的身份。这自然使我们紧张，因为这些规则要求我们改变传统习惯。所以如今全球领导者的关键问题是：如何使习惯和文化发展到融入更大的行星，同时不必牺牲鲜明特色和个人的骄傲？ 3 我的音乐旅程提醒了我，全球化带来的相互作用不只是摧毁文化；他们能够创造新的文化，生机，传播存在已久的传统。这不像生态“边缘效应”，它是用来描述两个不同的生态系统相遇发生了什么，例如，森林和草原。在这个接口，那里是最小密度和生命形式的最大的多样性，每种生物都可以从这两个生态系统的核心作画。有时最有趣的事情发生在边缘。在交叉口可以显示意想不到的连接。 4 文化是一个由世界每个角落的礼物组成的织物。发现世界的一种方式是例如通过深入挖掘其传统。例如音乐方面，在任何的大提琴演奏家的曲目的核心是由巴赫大提琴组曲。每个组件的核心是一个称为萨拉班德舞曲的舞蹈动作。这种舞蹈起源于北非的柏柏尔人的音乐，它是一个缓慢的、性感的舞蹈。它后来出现在西班牙，在那里被禁止，因为它被认为是下流的。西班牙人把它带到了美洲，也去了法国，在那里成为一个优雅的舞蹈。在1720年，巴赫公司的萨拉班德在他的大提琴组曲运动。今天，我扮演巴赫，一个巴黎裔美国人的中国血统的音乐家。所以谁真正拥有的萨拉班德？每一种文化都采用了音乐，使其具有特定的内涵，但每一种文化都必须共享所有权：它属于我们所有人。 5 1998年，我从丝绸之路发现在数千年来从地中海和太平洋许多文化间观念的流动。当丝绸之路合奏团执行，我们试图把世界上大部分集中在一个阶段。它的成员是一个名家的同等团体，大师的生活传统是欧洲、阿拉伯、阿塞拜疆、亚美尼亚、波斯、俄罗斯、中亚、印度、蒙古、中国、韩国或日本。他们都慷慨地分享他们的知识，并好奇和渴望学习其他形式的表达。 6 在过去的几年里，我们发现每一个传统都是成功的发明的结果。确保传统的生存的一个最好的方法是由有机进化，目前利用我们所有可用的工具。通过录音和电影；通过驻在博物馆、大学、设计学校和城市；通过表演从教室到体育场，合奏的音乐家，包括我自己，学习有用的技能。回到家中，我们和其他人分享这些技能，确保我们的传统在文化桌上有一席之地。 7 我们发现，在本国执行传统出口的是国外激励从业者。最重要的是，我们对彼此的音乐发展出了激情，并建立了相互尊重、友谊和信任的纽带，每一次我们都在舞台上这都是可触及的。这种欢乐的互动是为了一个理想的共同的更大的目标：我们始终能够通过友好的对话解决任何分歧。我们相互开放，我们形成一个桥进入陌生的传统，驱逐往往伴随着变化和错位的恐惧。换句话说，当我们扩大我们看世界的镜头的时候，我们更好地了解自己，自己的生活和文化。我们与我们的小星球的遥远的行星有更多的共同分享，而不是我们意识到的。 8 发现这些共同的文化是很重要的，但不只是为了艺术的缘故。所以我们的许多城市，不仅是伦敦，纽约，东京，现在即使甚至是中小城市正在经历着移民潮。我们将如何吸取同化有自己独特的习惯的人群？移民不可避免地会导致抵抗和冲突，就像过去一样？有什么关于德国的土耳其人口的阿尔巴尼亚人在意大利，北非人在西班牙和法国？文化繁荣的引擎可以帮助我们找出如何集合可以和平融合，同时不牺牲个性身份。这不是政治正确性。它是关于对人而言什么是珍贵的承认，和每一个文化已经给予我们世界的礼物。
human creations, language may be the most remarkable. Through language we share experience, values, exchange ideas, transmit knowledge, and sustain culture. Indeed, language is vital to sense of reality by giving meaning to events. 在人类所有的创造中，语言也许是影响最为深远的。我们用语言来分享经验，表达(传递？)价值观，交换想法，传播知识，传承文化。事实上，对语言本身的思考也是至关重要的。和通常所认为的不同的是，语言并不只是简单地反映现实，语言在具体描述事件的时候也在帮助我们建立对现实的感知。——语序的调整。 Good speakers have respect for language and know how it works. Words are the tools of a speaker’s craft. They have special uses, just like the tools of any other profession. As a speaker, you should be aware of the meaning of words and know how to use language accurately, clearly,vividly,and appropriately. 好的演讲者对语言很重视，也知道如何让它发挥更好的效果。词语是演讲者演讲的重要“武器”，具有特殊的用途，这和任何其他的工作技艺没什么两样。作为演讲者，必须知道词语的具体含义，也要懂得如何做到用词准确、清晰、生动、适当。 Using language accurately is as vital to a speaker as using numbers accurately to a accountant. Never use a word unless you are sure of its meaning. If you are not sure, look up the word in the dictionary. As you prepare your speeches, ask yourself constantly, “What do I really want to say? What do I really mean?” Choose words that are precise and accurate. 演讲者准确地使用语言和会计准确使用数字是一样重要的。确定词意后再措词。如果不确定，请先查词典。当你在准备演讲的时候，要不断地问自己：“我到底要说什么？我到底想表达什么意思？”用词一定要精准。 Using language clearly allows listeners to grasp your meaning immediately. You can ensure this [by using familiar words （that are known to the average person and require no specialized background）; by choosing concrete words in preference to more abstract ones, and by eliminating verbal clutter]. 用词清晰可以让听众迅速理解你的意思（抓到你的点）。要做到这一点，就要尽量使用一般人都熟悉的不需要专业知识就能懂的词语；多用具象词汇少用抽象词汇；还有要减少口误。 Using language vividly helps bring your speech to life. One way (to make your speech vivid)|is through imagery，or the creation of word pictures. You can develop imagery by using concrete language, simile, and metaphor. Simile is an explicit comparison between things （that are essentially different yet have something in common）; it always contains the words “like”or “as”. Metaphor is an impli cit comparison between things that are different yet have something in common; it does not contain the words “like” or “as”. 生动地用词能让演讲鲜活起来！比喻，这种能产生文字图像的修辞，可以使演讲达到生动的效果。比喻要用具象的语言，分为明喻和隐喻。 明喻是指在本质上有区别但仍然有相同点的事物之间做一个明确的比较，一般句中会含有“像”或“似”。隐喻则是一种隐藏的比较，不会出现like 和as 这些连接词。 Another way to make your speeches vivid is by exploiting the rhythm of language. Four devices for creating rhythm are parallelism, repetition, alliteration, and antithesis. Parallelism is the similar arrangement of a pair or series of related words, phrases, or sentences. Repetition is the use of the same word or set of words at the beginning or end of successive clauses or sentences. Alliteration comes from repeating the initial constant sounds of close or adjoining words. Antithesis is the juxtaposition of

The current development of genetically modified crops of China and its safety issues Zhang Qingfei (College of materials science and engineering, Nanchang University, 10001) Abstracts: GM technology as a new, highly efficient genetically modified technology, already widely used in the cultivation of new varieties of field crops. China's transgenic technology started earlier, China's current GM technology level in the forefront of the world, especially made great achievements in the cultivation of new varieties of crops. In this paper, the status quo using gene transfer on Chinese agriculture and safety of transgenic technology are introduced, and the resolve of GM safety issues some thought. On this basis, I made some new ideas of transgenic technology and application of transgenic technology development prospects were discussed. Keywords: GM technology; GM crops; GM safety issues; China Introduction: As the core of the biotechnology giant leap .Transgenic technology is known as the second "green revolution." In 1983, the world's first strain of transgenic tobacco plants marks the arrival of the era of gene transfer plants. In the ensuing decades, genetically modified crops developed rapidly. In 2014, there are 28 countries in the world planted GM crops, the planting area has reached more than 180 million hectares, Chinese genetically modified crops planting area is 3.6 million hectares. With the widespread planting of genetically modified crops, the impact of transgenic technology in agriculture is growing. As the research of GM crops, China has made great achievements in the research of rice and cotton. The development of anything will not be smooth. With the development of GM technology, its security deposit issues also be exposed. The safety of genetically modified crops has been disputed by people, opponents argue that GM crops have great potential risk, it should be resisted. What is more, some people exaggerate the risk of genetically modified crops. Aroused people's fear of genetically modified. In this paper, the people of GM crops concerns, the status of the development of GM crops were elaborated. Besides, security problems of genetically modified crops and their solutions will be discussed. The current development of genetically modified crops in china GM refers to the Technology that use molecular biology method to transfer the artificial separation and some modified biological gene to other species and change the genetic characteristics of the species .Plant transgenic technology is the genetic transformation of plants, making plants to meet human needs in aspects of shape, nutrition and consumer quality. China's biotech crop improvement research began in the 1980s, during the past 30 years, Chinese agricultural and biological high-tech has been developing rapidly. At present, China's hybrid rice, cotton and other advanced in the world. GM technology Applied on cotton, rice and other crops on behalf of China's development status of GM crops. As a cotton producing countries, the industrialization of Chinese insect-resistant cotton has brought huge economic and ecological benefits to Chinese

Unit 1 Text A 神经过载与千头万绪的医生 患者经常抱怨自己的医生不会聆听他们的诉说。虽然可能会有那么几个医生确实充耳不闻，但是大多数医生通情达理，还是能够感同身受的人。我就纳闷为什么即使这些医生似乎成为批评的牺牲品。我常常想这个问题的成因是不是就是医生所受的神经过载。有时我感觉像变戏法，大脑千头万绪，事无巨细，不能挂一漏万。如果病人冷不丁提个要求，即使所提要求十分中肯，也会让我那内心脆弱的平衡乱作一团，就像井然有序同时演出三台节目的大马戏场突然间崩塌了一样。有一天，我算过一次常规就诊过程中我脑子里有多少想法在翻腾，试图据此弄清楚为了完满完成一项工作，一个医生的脑海机灵转动，需要处理多少个细节。 奥索里奥夫人 56 岁，是我的病人。她有点超重。她的糖尿病和高血压一直控制良好，恰到好处。她的胆固醇偏高，但并没有服用任何药物。她锻炼不够多，最后一次 DEXA 骨密度检测显示她的骨质变得有点疏松。尽管她一直没有爽约，按时看病，并能按时做血液化验，但是她形容自己的生活还有压力。总的说来，她健康良好，在医疗实践中很可能被描述为一个普通患者，并非过于复杂。 以下是整个 20 分钟看病的过程中我脑海中闪过的念头。 她做了血液化验，这是好事。 血糖好点了。胆固醇不是很好。可能需要考虑开始服用他汀类药物。 她的肝酶正常吗？ 她的体重有点增加。我需要和她谈谈每天吃五种蔬果、每天步行 30 分钟的事。 糖尿病：她早上的血糖水平和晚上的比对结果如何？她最近是否和营 养师谈过？她是否看过眼科医生？足科医生呢？ 她的血压还好，但不是很好。我是不是应该再加一种降血压的药？药 片多了是否让她困惑？更好地控制血压的益处和她可能什么药都不吃 带来的风险孰重孰轻？

You can ensure this [by using familiar words （that are known to the average person and require no specialized background）; by choosing concrete words in preference to more abstract ones, and by eliminating verbal clutter]. 用词清晰可以让听众迅速理解你的意思（抓到你的点）。要做到这一点，就要尽量使用一般人都熟悉的不需要专业知识就能懂的词语；多用具象词汇少用抽象词汇；还有要减少口误。 Using language vividly helps bring your speech to life. One way (to make your speech vivid)|is through imagery，or the creation of word pictures. You can develop imagery by using concrete language, simile, and metaphor. Simile is an explicit comparison between things （that are essentially different yet have something in common）; it always contains the words “like”or “as”. Metaphor is an implicit
2015-2016学年第二学期学术英语理工类期中考试 班级:材料成型及控制工程145班学号：5901214047姓名：朱亿成绩: Computer Security The two following articles are on the security of computer.The first one was in the view of hackers,which was talking about the ways to utilize computer vulnerabilities. The first paper firstly redefines the term “hacker”, “cracker” and “getting inside” the computers and describes the procedure in detail. The term “unauthorized user” (UU) will be a better choice for defining the insider group. The known and unknown vulnerabilities will be taken advantage of by UUs ranging from poor password protection to leaving a computer turned on and physically accessible to visitors in the office. The first step of employing technical exploits will be the determination of the specifications of the target system. There are two ways of attacking including being through capabilities inherent in hypertext transfer protocol (http) and being preprogrammed against specific vulnerabilities and launched without any specific target.(Julie,2004) The variability of hacking action including the weak system and the strong system warns the users to choose the right way to protect the computer and do not authorize the computer to others easily. Lastly, the solution of avoiding vulnerabilities has been given, including updating patches, making complex passwords, getting information only from the reliable websites or services, updating anti-virus software and backing up the data to protect the computer not being hacked. Then,the second work was like a supplement to the first article.which involved getting imformaton only from the reliable websites,which was refered in the second article.Always,people are not to know how to use computer safely, update patches, make complex passwords, get information from the reliable websites or services, updae anti-virus software and back up the data to protect the computer not being hacked.So,this article would play a pivotal role in the aspect of computer security.It was a websites guide leading to the security imformation and service for acounts.This guide is intended to present a selected list of sites that cover the basic issues of computer security and which provide useful information for the non-expert (librarian, undergraduate student, office manager, etc.) who wants to learn more about this increasingly important subject. The categories are intended to offer points of departure for some of the many aspects
Is the cloud computing perfect now? Cloud computing, or the cloud, is a colloquial expression used to describe a variety of different types of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet. And with various terminals developing fast, the durative, massive and intricate computing related to these terminals really become urgent problems. And for the present, cloud computing is a solution. But if we allow the cloud computing to contact with our private information, is it secure enough? And in which field can we improve the security? In the Security Benefits of Cloud Computing, Felician Aleca introduced the cloud computing and analyze its extensive application in the Internet field. It clarified many advantages of the cloud computing. In addition, it also introduced some major security benefits for individuals or companies which are provided by the cloud computing. But nearly every Internet technique will produce some latent vulnerability. In an essay about computer hacker, How Do Computer Hackers “Get Inside”a Computer?, by Julie J. C. H. Ryan, it introduced the various ways that hackers use to invade into computer. And there are three major patterns of these ways, which are gaining access to the stored contents of a computer system, gaining access to the processing capabilities of system, or capturing information being communicated between systems (J.C.H.Ryan,2004). And in the end, it reminds the importance of protecting our computer. As we all known, the personal terminals always store many private information, and the cloud store the users’ data on the Internet servers , in this way, it will cause large-scale information leakage once the hackers invade to these servers online. In fact, we are becoming more vulnerable while we enjoy the benefit of centralized processing by cloud computing. So how to improve the security of the users’ data stored in the cloud is real ly worth studying. Reference Julie J. C. H. Ryan. How Do Computer Hackers “Get Inside” a Computer?.

Unit 4 翻译 环保的当今时代是约半个世纪之久。那段时间意识不断壮大，我们所面临的挑战知识增加，而重要的实践已经取得了进展，例如在一些减少各种污染，并在建立保护区。我们是，但是，仍然由协调人什么我们的星球能提供可持续的要求很远。 人与自然之间的不平衡的后果是出现在改变地球的气候，动物和植物的势头，并在关键的资源，包括野生鱼类资源，淡水和土壤的枯竭的大灭绝。而这些环境压力不是一成不变的。他们不断升级，随着我国人口的增长和国家继续为更多的经济增长的不懈追求。 如果我们要避免这些趋势的最严重后果则毫无疑问是较为迅速的进展将需要比迄今取得的，但我们在这里应该关注我们的努力？什么可能是在未来的半个世纪行动的优先领域？ 这让我感到眼前的主要挑战主要不是相对于良好的信息，更好的技术和良好的政策思路。这些东西是至关重要的当然的，但所有这些东西都已经可用。我们知道如何让清洁电力，节约资源，培育生物多样性。我们知道如何规范污染，防止损坏的生态系统，如果我们想。我们有这些能力的事实是不够的。 如果我们继续前进的决定性方式的争论它需要被重新定义。我们需要从“做正确的事'上移动，谈到风险管理，促进抗灾能力。 要查看关爱地球的自然系统为某种道德选择的是完全误解了危机，我们都在这个挑战是关于人类社会的未来，而不是一些可选的慈善事业，我们可以留给慈善事业慷慨解囊，做社会改良。嵌入了使我们从保护自然的人们保护自然为人们的叙述是这样的重新规划的重要组成部分。我们正处在一个时期的后果，世界必须知道，健康的本质不是一些可选的精密而是一组不可缺少的物质资产。 如果这样的叙述是为了获得实际效果再想找性质后必须立即被看作不仅是一个环境的挑战，也是一个经济问题。只要我们继续滑向两个方向行进，一方面是促进环保目标的同时，对其他直接矛盾与措施，以实现更多的经济增长，我们不再将无法取得真正的进展。 当涉及到经济学和生态学有大量的好思已经完成。例如，在不同的经济措施，以取代成功与失败，生态税的改革更为现实的措施，收入转移的负担，污染，生态系统服务补偿，补贴的重定向和如何调动国内生产总值的原油措施融资以扩大清洁行业。 我们必须在经济进行转型能够在工作丰富和更平等带来许多其他社会福利，从更健康。它，然而，需要政治支持。这是流行文化就变得非常重要。 在许多国家已经采取了保留的消费文化是非常多的GDP-增长模式的合作伙伴。两个一起去，随着消费前积极推动以提高后者的扩张。从这个意义上它是很难改变的经济思想也没有改变流行文化塑造那些相同的经济假设。这是不容易的。消费主义是我们很多人有吸引力的文化空间居住。它发挥我们的默认设置，并为我们与生俱来的倾向，以促进地位，自我表达和短期的舒适度。 移的流行文化将需要比简单地告诉人们他们错了想要的消费品了。这到目前为止还没有成功，这可能不会在今后的工作中无论是。另一种更复杂的方法是必需的，或许是时尚大师们和其他非环保意见领袖领导。 不幸的是，以上。无论怎样引人注目的叙述，在我看来既不经济也不是文化将改变，直到有一个不同的哲学背景下塑造我们共同的世界观。 在大多数国家，今天还有就是看技术，而不是本质，作为改善人民生活的任务，我们的首选合作伙伴世界观。对于我们大多数人的本性是无关紧要的。更糟糕的是自然环境有时表现为对发展的阻力，且不方便载重吨减慢人类进步的漫长旅程。只要这种世界观保持甚至部分完好无损然后文化变革和改革对准经济思想与生态容量是的，我害怕，几乎是不可能实现的。改变社会“的世界观是一个巨大的工作，但也不是没有可能。我们看世界的方式是不是一个给定的，它的形状，并且它可以在更生态方向，以及自毁那些移动。各国可以引入自然史研
