Unit 9 Polymers 聚合物Polymers are all around us. They are the main components of food (starch, protein), clothes (silk, cotton, polyester, nylon), dwellings (wood-cellulose, paints) and also our bodies (nucleic acids, polysaccharides, proteins). No distinction is made between biopolymers and synthetic polymers. Indeed many of the early synthetic polymers were based upon naturally occurring polymers, e.g. celluloid (cellulose nitrate), vulcanization of rubber, rayon (cellulose acetate).聚合物与我们的生活密切相关。
他们是食物（淀粉，蛋白质）、衣物（丝绸，棉花，聚酯，尼龙）、建筑房屋（木纤维素，油漆）和我们身体（核酸，多糖，蛋白质）的主要成分。
生物高聚物和合成聚合物之间没有差别。
实际上许多早期的合成聚合物是基于天然形成的聚合物而合成的，比如，赛璐珞/电影胶片（硝酸纤维素），橡胶硫化，人造纤维（醋酸纤维素）。
Polymers are constructed from monomer units, connected by covalent bonds. The definition of a polymer is:聚合物是由单体单元通过共价键连接而成的。
聚合物的定义是：―a substance, —R—R—R—R—or, in general —[R]n—, where R is a bifunctional entity (or bivalent radical) which is not capable of a separate existence‖是—R—R—R—R—或者，一般来说，—[R]n—构成的物质。
R是一种双官能团的物质（或者二价自由基），而这两种官能团是不能分开单独存在的。
Where n is the degree of polymerization, DP n. This definition excludes simple organic and inorganic compounds, e.g. CH4, NaCl, and also excludes materials like diamond, silica and metals which appear to have the properties of polymers, but are capable of being vaporized into monomer units.在这里n代表的是聚合度，DP n。
这个定义不包括简单的有机和无机物质，比如，CH4, NaCl，同时也不包括像钻石，硅石和金属等材料，这些材料看起来具有聚合物的性质，但是能够蒸发成单体单元。
The molecular weight (MW) (strictly relative molecular mass) can be obtained from the MW of the monomer (or repeat unit) multiplied by n. Thus the MW of CH4or NaCl is 18 or 58.5 respectively, whereas the MW of a polymer can be > 100. When the value of n is small, say 2-20, the substances are called oligomers, often these oligomers are capable of further polymerizations and are then referred to as macromers.分子量（严格来说是相对分子质量）可以由单体（或重复单元）乘以n获得。
于是，CH4或者NaCl 的分子量分别为18或者58.5，而一个聚合物的分子量能大于100。
当n的值较小时比如说2到20，这种物质叫做低聚物，通常这些低聚物可进一步聚合，成为高聚物。
By definition, 1 mole of a polymer contains 6×1023 polymer molecules and therefore 1 g mole = MW of the polymer in grams, which, in theory, can be > 106 g. However, by convention, 1 g mole usually refers to the MW of the repeat unit; thus 1 g mole of polyethylene —(CH2)n— is taken as 14 g (the end groups, being negligible, are ignored).6×1023: six times ten to the power of 23, 6×10-23: six times ten to the power of minus 23.106: ten to the power of six or ten to the tenth power.由定义，1摩尔高聚物含有6×1023个高聚物分子，因此1克摩尔等于以克作单位的高聚物的分子量，理论上它可大于106克。
但习惯上，通常1克摩尔指重复单元的分子量；这样1克摩尔聚乙烯-(CH2)n- 可认为是14克（末端基团可以忽略）。
A polymer with a MW of 107, if fully extended, should have a length of ～1 mm and a diameter of ～0.5 nm. This is equivalent in size to uncooked spaghetti ～2 km in length. However, in reality, in bulk polymers the chain is never fully extended – a random coil configuration is adopted sweeping out a space of diameter ～200 nm. It therefore has the appearance of cooked spaghetti or worms (or more correctly, worms of different length). The movements of these polymer chains are determined by several factors, such as:一个分子量为107的高聚物，若完全展开，其长度约1mm，直径约0.5nm.这相当于约两公里长的生的意大利面条。
但是，实际上，在大多数高聚物中的链决不是完全展开的——一个任意的圈式结构被采用，占有约200nm直径的空间。
因此看来像煮熟的意大利面条或蠕虫，这些高聚物链的转移由几个因素来决定，如：(i) Temperature(ii) Chemical make-up of the backbone —C—C—C—chain; whether the chain is flexible (aliphatic structure) or rigid (aromatic)(iii) The presence or absence of side-chains on the backbone(iv) The inter-polymer chain attraction (weak—dipole/dipole, H-bonding —or strong covalent bonds, cross-linking)(v) The MW and molecular weight distribution (MWD) of the polymer.(i)温度(ii)骨架-C-C-C-链的化学组成;不管链是柔性的或是刚性的(iii)骨架上是否有支链存在(iv)共聚物链的引力(v)聚合物的分子量和分子量分布。
Nearly all of the properties of polymers can be predicted if the above factors are known, e.g. whether the polymer is amorphous or partially crystalline; the melting temperature of the crystalline phase (T m) (actually it is more of a softening temperature over several degrees); is the polymer brittle or tough; its rigidity or stiffness (called modulus), whether the polymer dissolves in solvents, etc.若上述因素已知，可以预测聚合物的几乎所有的性质，比如此聚合物是非晶的还是部分晶状；晶态的融化温度；聚合物是脆的还是韧性的；它的刚性，此聚合物是否溶于溶剂等。
Polymers are really effect chemicals in that they are used as materials, e.g. plastics, fibers, films, elastomers, adhesives, paints, etc., with each application requiring different polymer properties. Many of the initial uses of plastics were inappropriate, which led to the belief that plastics were: ―cheap and nasty‖. However, recent legislation on product liability and a better understanding of the advantages and disadvantages of plastics have changed this position.聚合物的确能对它们制成的化学品产生影响，如塑料，纤维，胶卷，合成橡胶，粘合剂，涂料等，每一种用途都要求不同的聚合物特性。

当我伤心或劳累的时候,我不看剧情片或纪录片。
像《泰坦尼克号》这样的剧情片只会让我更伤心。
像《帝企鹅日记》这样的纪录片,(通常)会针对某个特定话题提供丰富的信息,(内容)也很有趣,但是当我累的时候,我不想思考太多。
当我太累不想思考时,我不介意看像《蜘蛛侠》这样的动作电影。
我只想屏蔽我的大脑,坐在那里观看一个令人兴奋的超级英雄,他总是能在关键时刻挽救世界。
偶尔我会喜欢看恐怖片。
虽然它们很有意思,但是我会因为太害怕而不敢独自一人看,我总会带上一位不怕这些类型的电影的朋友(一起看),这样就觉得没那么可怕了。

Unit 9 Kids and Computers Digital Danger 课文翻译
Unit 9Kids and Computers: Digital DangerAlison Sperry1. There's a familiar saying, "Play is children's work." Through play, people who study child development tell us, children develop the skills and outlooks that determine the adults they will become. Playing house or school, for example, helps them "try on" the roles of Mom or Dad or teacher. Athletic activities help kids develop coordination, learn to work as part of a group, and gain confidence and a sense of fair play. Even solitary activities like reading connect children with the wider world, encouraging a sense of empathy with the greater human family.2. But in very recent years, other forms of entertainment have had an enormous impact on growing children. For many kids, computer activities and video games now take up much --even most -- of the time formerly devoted to more traditional forms of play. Entering adulthood now are the first Nintendo babies, a generation raised more on Virtual Boy and Mortal Kombat than baseball and Uncle Wiggly. How have they been affected by this change in the concept of "play"? Social scientists, parents, and talk show pundits will be debating the question for years to come. But we can start drawing our own conclusions. As amusing and ingenious as electronic entertainment can be, children -- and society they live in -- are the losers when they rely on these forms of fun. Unlike traditional games and toys, "wired" entertainment encourages kids to be unimaginative, socially immature, and crudely desensitized to the world around them.3. Watch a child take a ball of Play-Doh in her hand and begin to roll it experimentally. First it's a simple ball, then a snake. The snake might become a figure eight or a bracelet. She coils the bracelet on top of itself to create a pot that she uses for a make-believe tea party. Next she smashes the pot back into a ball, which may next morph into a snowman, a horse's head, a bunny, a sea serpent, or a skyscraper. With nothing but her hands and an inexpensive chunk of flour and salt, she forms a universe in which she makes the rules and creates the inhabitants. When she tires of it, she can wad it back into a shapeless mass that awaits her next creative impulse. The act of playing with the Play-Doh sparks other interests —maybe she'll work with modeling clay that she can bake into a permanent form, or paints, or papier-mâché Although she doesn't give what she's doing a great deal of thought, she's learning something valuable: I am a creator. I can give my ideas tangible form.4. A video game, on the other hand, is cynically programmed to give the illusion of creativity. The player is given various choices at every turn —Which door will I go through? Which weapon will I use? What clue shall I read? — But they are choices in the same sense that a pigeon's pecking at a lever to get a grain of corn is a choice. The player is as much a tool of the game as the joystick. Her momentary fun is unsatisfying because it leads not to any genuine sense of achievement but only to the hypnotic experience of watching someone else's creation unfold. Hand a ball of Play-Doh to a child reared on the sterile adventure of video games, and you're apt to get a blank look and the hesitant question, "What do I do with it?" The video game player learns her own lesson: I don't create. I let someone else's creativity happen in front of me.5. It's a beautiful Saturday in autumn, and a group of kids are playing a pickup game of soccer. A dispute arises about whether a kick went over the foul line. Some of the kids are sure it did; others insist that it did not. Voices are raised; tempers flare. Maybe a hothead or two will stalk off the field. But the sky is crystal blue, and there are chores waiting at home. Making a quick calculation about the relative benefits of continuing the game, the players work out a solution. Maybe they replay the kick. Maybe they flip a coin. Maybe they agree to say that the ball was fair, or foul. Their willingness to compromise, to accept the idea that such give-and-take is part of life, allows the game to proceed. The players move on, having learned a small lesson about getting along with others.6. Contrast that scene with the world of the Internet chat rooms, where many adolescents spend uncountable hours. On that same lovely Saturday, a young Internet queen hunches over her keyboard, alone in her room. Her buddy list includes dozens, even scores, of "friends" she's never met. Her fingers fly across the keyboard as she races from one dialogue box to another, keeping up multiple conversations. These are peculiar conversations, however, including none of the vulnerability that is part of real-world friendship. In the buddy-chat world, status is based on the ability to keep up a rapid pace of one-liners, insulting zingers, caustic put-downs. The chat queen's most intimate friendships take the form of brief alliances with buddies who join with her to "flame" another chatter who has displeased them. If that ally eventually becomes annoying, too, zap! She can instantaneously erase him from her buddy list, or even block him so he is unable to contact her again. It's no great loss. There are literally millions of new acquaintances waiting to be picked up in a chat room to fill that void. The lesson: I shouldn't have to work at relationships. They come and go instantly and at my convenience. If someone displeases me, I can make that person disappear.7. When kids sit down to play Monopoly, they form a loosely knit group that is still part of the world around it. When company arrives at the house, it's no problem to halt thegame briefly. The players can greet visitors, laugh together, talk about the game, even quickly rearrange it to include new players. Even after the game continues, chatting with other players and non-players is easily accomplished. Despite their involvement in the game, the players are not ruled by it. Human contact, courtesy, and communication are not seen as threats to their enjoyment. They are learning that they can enjoy their own activities and still be sensitive to the larger world around them.8. Contrast this board game scene with one that has become depressingly familiar in many living rooms. Visitors arrive at a home to find a child hunched in front of the TV set, video controls in his lap. Even when spoken to directly, he does not pull his eyes from the screen. "I'm playing!" is his furious response if the visitors persist in trying to engage his attention. Far too often, even his parents, intimidated by the high-priced, high-tech gadget that has sucked their child's humanity away, tiptoe around rather than disturb him. The game itself is all too likely to be one that presents the most hideous suffering as entertainment, with the player in the role of psychotic killer -- maybe in Duke Nukem, with its "twenty-three levels of nonstop carnage!" or Bloody Roar, which offers the player "more ways to maim, crush, and devour your enemies than ever."9. The lesson?10. Isn't it too awful to think about?1. 有一句众人皆知的俗语：“玩是孩子们的工作。

Unit 9 What Is Happiness?The right to pursue happiness is issued to Americans with their birth certificates, but no one seems quite sure which way it runs. It may be we are issued a hunting license but offered no game. Jonathan Swift seemed to think so w hen he attacked the idea of happiness as “the possession of being well-deceived,” the felicity of being “a fool among knaves.” For Swift saw society as Vanity Fair, the land of false goals.自从呱呱坠地，美国人就被赋予了追求幸福的权利，但似乎没人确信幸福究竟在哪里。

It is, of course, un-American to think in terms of fools and knaves. We do, however, seem to be dedicated to the idea of buying our way to happiness. We shall all have made it to Heaven when we possess enough.当然用傻子、骗子这样的字眼来形容是不合美国的人的风俗习惯的，然后我们似乎确实沉溺于用金钱购买幸福的想法：只要有足够的钱，我们百年后就能上天堂。
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。

UNIT 9 What Is Intelligence, Anyway课文翻译大学英语二
Unit9 What Is Intelligence, Anyway?Isaac AsimorAsimov explains why there is much more in intelligence than just being able to score high on intelligence tests.What is intelligence, anyway? When I was in the army I received a kind of aptitude test that all soldiers took and, against a normal of 100, scored 160. No one at the base had ever seen a figure like that and for two hours they made a nig fuss over me. (It didn't mean anything. The next day I was still a buck private with KP as my highest duty.) All my life I've been registering scores like that, so that I have the complacent feeling that I'm highly intelligent, and I expect other people to think so, too. Actually, though, don't such scores simply mean that I am very good at answering the type of academic questions that are considered worthy of answers by the people who make up the intelligence tests - people with intellectual bents similar to mine?For instance, I had an auto-repair man once, who, on these intelligence tests, could not possibly have scored more than 80, by my estimate. I always took it for granted that I was far more intelligent than he was. Yet, when anything went wrong with my car I hastened to him with it, watched him anxiously as he explored its vitals, and listened to his pronouncements as though they were divine oracles - and he always fixed my car.Well, then, suppose my auto-repair man devised questions for an intelligence test. Or suppose a carpenter did, or a farmer, or, indeed, almost anyone but an academician. By every one of those tests, I'd prove myself a moron. And I'd be a moron, too. In a world where I could not use my academic training and my verbal talents but had to do something intricate or hard, working with my hands, I would do poorly. My intelligence, then, is not absolute. Its worth is determined by the society I live in. Its numerical evaluation is determined by a small subsection of that society which has managed to foist itself on the rest of us as an arbiter of such matters.Consider my auto-repair man, again. He had a habit of telling me jokes whenever he saw me. One time he raised his head from under the automobile hood to say: "Doc, a deaf-and-dumb guy went into a hardware store to ask for some nails. He put two fingers together on the counter and made hammering motions with the other hand. The clerk brought him a hammer. He shook his head and pointed to the two fingers he was hammering. The clerk brought him nails. He picked out the sizes he wanted, and left. Well, doc, the next guy who came in was a blind man. He wanted scissors. How do you suppose he asked for them?"I lifted my right hand and made scissoring motions with my first two fingers. Whereupon my auto-repair man laughed heartily and said, "Why, you dumb fool, he used his voice and asked for them." Then he said, smugly, "I've been trying that on all my customers today." "Did you catch many?" I asked. "Quite a few," he said, "but I knew for sure I'd catch you." "Why is that?" I asked. "Because you're so goddamned educated, doc, I know you couldn't be very smart."And I have an uneasy feeling he had something there.阿西莫夫说明了为什么智力远非只是在智力测验中取得高分。

The importance of this task is stressed by scientists who study the relation of man to nature.These scientists are called ecologists,from the Greek word oikos,which means home.Ecologists are responsible for keeping the land,air and water clean.”How are we doing?”an ecologist was asked recently.”Lousy,the scientist said,sniffing the fume-laden air.”We’re got to do a better job-and soon-or it will be too late.”研究人与自然关系的科学家强调了这个任务的重要性。
这些科学家被称为生态学家，这个词源于希腊语oikos，意思是家。

”Consume,consume,consume!Our society is consumer oriented-dangerously so.To keep the wheels of industry turning,we manufacture consumer goods in endless quantities,and ,in the process,are rapidly exhausting our natural resources.But this is only half the problem.What do we do with manufactured products when they are worn out?They must be disposed of,but how and where?Unsightly junk-yards full of rusting automoniles already surround every city in the nation.Americans throw away 80 billion bottles and cans each year,enough to build more than ten stacks to the moon.There isn’t room for much more waste and yet the factories grind on.They cannot stop because every one wants a job.Our standard of living,one of the highest in the world,required the consumption of manufactured products in ever-increasing amounts.Man,about to be buried in his own waste,is caught in a vicious cycle.”Stop the world ,I want to get off.”is the way a popular song put man’s dilemma.消费，消费，消费！我们的社会是以消费者为中心的，而这是非常危险的。
