Unit 1 Dream DateHost：Hello, everyone, and welcome to Dream Date, the game where one lucky woman gets to choose her perfect date. I‟m your host, Lucky Chance. Now, let‟s meet our first contestant.Announcer: Lucky, meet Sarah Hawkins, a social studies teacher from Ames, Iowa. Host：Hello, Sarah, and welcome to Dream Date.Sarah: Hi, Lucky. It‟s great to be here.Host：Now, Sarah, before we bring out our three bachelors, why don‟t you tell us something about yourself?Sarah: Well, I‟m twenty-eight years old. I‟m interested in American history and government. I…I enjoy talking about politics, literature, the arts…about a lot of things, really.Host：And what qualities do you look for in a guy?Sarah: Well, I like someone who‟s honest and straightforward, and someone who‟s a good conversationalist. Also, I like it when someone is more interested in other people than he is in himself. I think that‟s really important.Host：Well, those are all good qualities. Is there anything you don‟t like in a guy? Sarah:Well, I can‟t stand it when a guy talks about himself all the time. That‟s something that really bothers me.Host：Well, Sarah, now that we know a little about you, why don‟t you have a seat? And let‟s bring out our three bachelors so you can choose your “dream date.”Host：Welcome, gentlemen. It…s good to have you with us. Would each of you like to say hello to Sarah? Bachelor Number 1.Bachelor 1: Y o, Sarah.Host：Bachelor Number 2.Bachelor 2: Hi, Sarah.Host：And Bachelor Number 3.Bachelor 3: Hello, Sarah!Host：Thank you, bachelors. Ok, Sarah, let‟s get started. Go ahead and ask your first question. And remember, you have to make your choice based on the answers you receive.Sarah: Ok. Bachelor Number 1. If you were out with your friends and then showed up late for our first date, what excuse would you give when you arrived?Bachelor 1: Well, I‟d be too embarrassed to tell you the truth, so I‟d probably say that I had a car trouble or got stuck in traffic or something.Sarah: Ok, Bachelor Number 2, same question.Bachelor 2: Well, it really bothers me when people lie-and I wouldn‟t want to start our relationship on a lie-so I would tell you the truth, and I‟d hope you‟d be generous enough to forgive me.Sarah: Bachelor Number 3?Bachelor 3: Well, that‟s happened on other dates, as a matter of fact. I‟d probably be honest with you and tell you what I tell everyone: “I‟m sorry, but, uh, it‟s hard to divide my time among so many people!”Sarah: Oh, really? Ok. Uh, Bachelor Number 1, what‟s your idea of the ideal date?Bachelor 1: Well, I think getting together with a bunch of my friends, having a barbecue, and heading out to a football game. Yeah, that would be a great date. Sarah: OK. Uh, Bachelor Number 3, same question.Bachelor 3: For me, I think I would take you to my favorite nightclub where everybody knows me.Sarah: And how about you, Number 2? What‟s your idea of the perfect date? Bachelor 2: I‟d take you out to a nice dinner. That way you could relax and enjoy the evening, and we could get to know each other better.Sarah: Great. OK. Uh, Bachelor Number 2, tell me two things about yourself: one positive and one negative.Bachelor 2: Well, let‟s see. I…I think I‟m a pretty good friend, and people trust me. Uh, negative…I‟m very direct, and that sometimes upsets people.Sarah: Oh, no, that‟s good, Number 2, Uh, number 3, tell me something good about yourself and something not so good.Bachelor 3: Actually, I‟m pretty good at most things I do. And something not so good….I can‟t think of anything.Sarah: OK. Uh, Bachelor Number 1, tell me something positive and something negative about yourself.Bachelor 1: Well, I guess I‟m pretty easygoing. That‟s something good about me. Something bad. Well, I guess I‟m not very ambitious. I mean, I don‟t care if I make a lot of money or save the world. I just like watching sports with my friends.Host: OK, Sarah. Let‟s have a few final questions, and then you‟ll have to make your choice.Sarah: OK. Uh, Bachelor Nu mber 1, finish this sentence: “I can‟t stand it when…”Bachelor 1: I ca n‟t stand it when people are talking while I‟m watching the football game on TV.Sarah:OK. Uh, Bachelor Number 3, finish this sentence: “I think it‟s disgusting when…”Bachelor 3: I think it‟s disgusting when I‟m at an expensive restaurant and I don‟t get the service I deserve.Sarah: OK. Bachelor Number 2: “It really bothers me when…”Bachelor 2:It bothers me when people get mad and they get into arguments over unimportant things. I just think people should be more easygoing and treat each other better.Host: OK, Sarah. We‟re out of time. Now I‟m going to ask you to make a choice based on the answers you received. Who will that special date be with? Will it be Bachelor Number 1,…Number 2,…or Number3?Sarah: Well, they all sounded really nice, but I think I‟m going to choose Bachelor Number2.Host: Great! OK. Was there any specific reason?Sarah: Oh, well, like I said, they all sounded like great guys, but I like what Number2 said about being late for a date and being able to trust him. I appreciate it when people are honest with me. Also, he seemed interested in doing things to please me and not just himself.Host: Well, before we meet your “dream date”, let‟s say hello to the two men you didn‟t choose.Announcer: Sarah, Bachelor Number 1 is twenty-nine years old. He‟s a former college football star from Pocatello, Idaho. He says he loves playing or watching almost every kind of sports. Sarah, meet Kevin Banks.Sarah: Hi.Bachelor 1: See you.Announcer: Bachelor Number 3 is a thirty-year-old actor from Los Angeles. He says everyone should recognize him from his role on the soap opera My World. Sarah, meet Chip Billings.Bachelor 3: Sarah.Sarah: Chip.Bachelor 3: Y our loss!Announcer: And finally, your choice: Bachelor Number 2. He comes from your own hometown of Ames, Iowa.

We went to high school together.Jim: Sar ah Hawkins? I don‟t believe it! I thought you moved back East after graduation.Sarah: And I thought you went to…Host:Well, once again, one lucky woman finds her “dream date”. That‟s our show.

Unit1Transcript Lesson One Audio StudioClip 1Melting Polar IceThe latest evidence comes from opposite ends of our planet, but the story it tells is thesame. At the North Pole, new satellite photos show Arctic ice is melting so fast, many scientists now predict it will be gone within 30 years. Some researchers think it could disappear in just six. At the South Pole, an ice shelf the size of Connecticut is in danger of melting because theice bridge that held it in place has shattered. It’s one of ten ice shelves that have shrunk or collapsed in the past 50 years. Some were 10,000 years old. Polar ice works as the earth’s airconditioner. Without it, there could be a snowball effect with temperatures rising even faster. Governments all around the world have to take the lead in solving this crisis, but eachof us has to do our part to reduce greenhouse gasses. If we all don’t take bold action — and take it soon — we will all find ourselves on very thin ice. If we’re lucky.Warm-up1）A string of warmer years 2）Polar ice is melting fast 3）Extreme weathersTask 1 Note-taking1) opposite ends of our planet 2) North 3) melting so fast 4) it will be gone within 30 years 5) it could disappear in just six 6) South 7) in danger of melting 8) shattered 9) 5010) one of ten11) shrunk12) collapsed13) 10,000Task 2 Dictation1) as the earth’s air conditioner 2) a snowball effect with temperatures rising even faster 3)take the lead in solving this crisis 4) do our part to reduce greenhouse gasses 5) all find ourselves on very thin iceClip 2 Who Is Paying the Price for Climate ChangeClimate change is already melting the Arctic, queering weather and threatening foodsupplies. So who’s paying the price for all these global warming impacts It might seem likeinsurers are most at risk. Indeed, insurers did pay out some $33 billion in climate-related damages last year in the U.S. alone. But it turns out that bearing the brunt of climate change costs is you, the taxpayer. A new analysis by the Natural Resources Defense Council, the NRDC, finds that the federal government spent three times more than the private insurance industry on climate change impacts last year. And, of course, those federal efforts are entirely funded by taxpayers.“It is in effect a climate disruption tax, equivalent to a 2.7 percentage point increase in what Americans paid in sales taxes last year.” That's Daniel Lashof, director of the NRDC's Climateand Clean Air Program and co-author of the report. We spent nearly $100 billion in 2012 on drought-related crop insurance, storms like Hurricane Sandy, floods and wildfires. By comparison the nation spent $95 billion on education last year and just $91 billion on transportation. Greenhouse gas pollution shows no signs of slowing, recently touching 400 parts-per-million. And as that number continues to rise, so will the price.Task 1 Note-taking1) insurers 2) risk 3) out some $33 billion 4) damages5) taxpayer 6) three times more than7) funded by taxpayersTask 2 True or False1) T 2) F 3) FLesson Two Audio StudioClip 1 Brighter LivingWith all the news about climate change, sometimes reversing it or slowing it down seemsimpossible, but it’s not. The key is making small simple changes in your daily life. Then multiply that by the millions of us, and we’ve got real results in the long run. Install aprogrammable thermostat that adjusts itself when you are not at home so you are not cooling or heating an empty house. If every home in America did this, the reduction in greenhouse gas emissions would be the same as taking six millions cars off the road. Next, wash your clothes in cold water instead of hot. Look for appliances that have been given the energy star seal of approval by the EPA. These models use ten to fifty percent less energy than standard models. Buy fresh foods whenever possible. Frozen foods use ten times the energy to produce and get to the supermarket. Finally, head to your home improvement store and pick up an insulation blanket. They go from ten or twenty bucks, to wrap around your hot water heater.Warm-up1) buy fresh food whenever possible 2) buy and wear clothes made of eco-friendly materials 3) save electricity, water 4) take more public transportation, ride bicycles or just walkTask 1 Note-taking1) programmable 2) adjusts 3) cooling or heating an empty house 4) in cold water instead of hot 5) appliances that have been given the energy stars 6) fresh foods whenever possible7) home improvement storeTask 2 Sound Club1) multiplied up 2) millions of us 3) greenhouse gas emissions 4) taking six millions cars offthe roadClip 2 Huston University-reduce University Carbon FootprintThe University of Houston is emerging as a leader in sustainability, working to reduce its carbon footprint. The University of Houston is looking at how can we lead in sustainability worldwide. What does that really mean So, leadership for sustainability is about building relationships, about heightening dialogue, heightening our critical thinking, really talking about the needy issues. The efforts are educational, like turning the eighty-eight solar panels donated through a grant from Green Mountain Energy into a learning opportunity for engineering students as well as enriching, such as the community garden tended by students.“We grow produce that we then donate to local food pantry and students are the primary volunteers for this garden. It’s really close by to where we live and it’s kind of important for us to give back to literally the local community in which we are living and that’s part of the idea about sustainability. Connecting to community, seeing what their needs are, seeing what our resources and our needs are, things like that.”Warm-up1) enhance the public’s awareness; promote actions; …2) educational efforts in various formshelp organize environmental protection campaigns in daily life, such as garbage classification Task 1 Note-taking1)reduce its carbon footprint 2)building relationships 3)heightening dialogue 4)heightening our critical thinking5)talking about the needy issuesTask 2 Dictation1)turning 2)donated 3)enriching 4)tended 5)grow6)donate 7)live8)give 9)Connecting10)seeingHome Listening1) push 2) effort 3) concept 4) Alternative 5) resources 6) elements 7) as complex as 8) deal with 9) over the next few decades 10) positive changesUnit2Transcript Lesson One Audio StudioClip 1Are People Inherently Good or BadThe argument between nature and nurture influencing how we behave has been had many times. But now scientists are studying infants to try to understand if we are inherently good or bad. Yale University researchers working with infant children have had some interesting results. They staged a puppet show in which one puppet is trying to go uphill but keeps falling back down. Two more puppets appear; one that wants to help the first figure up the hill and another that is trying to push them back down. What the researchers found was that after the puppet show, when given the choice, the infants reach down for the puppet that tries to help the other one push uphill rather than the other one who is trying to push them both back down. In another study the same researchers introduced a neutral character thatdidn’t try to help or hinder the work. The infants still chose the helper over the neutralcharacter but also chose the neutral character over the one trying to hinder the progress. Scientists think this means that even infants with no language abilities can identify with motivations and are prone to like things that help them achieve rather than things that try to hold them back.Task 1 Note-taking1) Two 2) Infant children 3) Two puppet shows 4) reach down for the puppet they like 5) the helper 6) the neutral character 7) the neutral character 8) trying to hinder the progress 9) infants 10) language abilities 11) help them achieve 12) hold them backTask 2 Dictation1) stage 2) falling 3) appear 4) push 5) found 6) reachClip 2 Nature vs. Nurture-parent InfluenceWe are all born with certain physical characteristics determined by our genes, but does our DNA dictate how we act William R. Clark: Genes may very well determine how we behave in given situations.Dr. Dean Edell: Researchers say they are learning now that genes help control how we interpret our environment. Steven Pinker: There has to be some kind of innate circuitry in place that allows us to create culture and acquire culture and do the learning. Dr. Dean Edell: But can environment influence which genes are triggered David Moore: What really matters is which genes are turned on and which genes are turned off, and different genes are turned on and off in different circumstances. Dr. Dean Edell: That leaves to debate over the role parents play in influencing their children. Steven Pinker: Parents aren't the only aspect of the environment; there is also the surrounding culture. Dr. Dean Edell: Some believe the stronger social influences happen outside the home. Judith Rich Harris: Children live in separate worlds and each world is very important, but there is very little carry-over from one world to the other, and what is carried over is whatever is genetic. Dr. Dean Edell: Controversial author, Judith Rich, says how well a child turns out is up to the child, not the parent. Others find that troubling. Stanley Greenspan: We encourage parents to be either passive or hopeless or helpless in the face of certain challenges that they would assume were genetic. Male Speaker: As the debate rages, what's clear is that as scientists study DNA, they are learning more about ways to fight disease and perhaps understand better what makes us tick.

You can help keep your brain young with somesimple lifestyle changes such as: moderate amount of exercise, eating well, managing your stress. Exercising three to five times a week increases blood flow to the brain which keeps it working smarter and reduces the risks of mini strokes ( transient ischemic attack 短暂性缺血发作). It’s fairly common when we see someone with early memory troubles we’ll see acertain degree of mini strokes that have occurred over time. Healthy eating will alsodecrease stroke risk. Foods rich in omega-3 fatty acids, like fish and walnuts are very important for brain health. It seems that people who eat a lot of fish and sea food tend to have a healthier brain aging overall. As to those eat a plant-based diet and reducing the stress through meditation also helps keep our brains younger longer. Significant stress causes brain changes that can lead to memory loss. Doctor Hu says mediators tend to have better bloodflow to the brain’s frontal cortex — the area where one must use to stay sharp andmulti-task and make accurate decisions. So if you want to stay smarter longer, take steps now to improve your lifestyle by exercising, eating right and meditating. For today’s health minute, I am Susan Hendricks.Task 1 Note-taking1) Moderate amount of exercise 2) Working smarter and reduces the risks of mini strokes 3) Eating well 4) Very important for brain health 5) Managing your stress 6) Brain changes that can lead to memory loss.Task 2 Short Answer Questions1. A certain degree of mini strokes.2. People who eat a lot of fish and sea food.3. Meditation.Clip 2 Keep Your Brain Smart with Simple ChangesGood morning in today in Healthwatch. Nature nurtures creativity. Disconnecting from our digital devices seems to become more difficult every day. But there is now one more reasonto take a vacation in the great outdoors. A new study finds spending time with nature is good for your mind. It even improves problem-solving abilities and creativity by fifty percent. Researchers looked at fifty six people with an average age of 28 and split them into two groups. The first took a creativity test before a backpacking trip, and the second took on the fourth day of the trip. Those who took it before had an average score of about 4. And those who took it on the fourth day scored just about 6. The second group was not only more creative, but also better at problem solving. Researchers cannot say whether the improvements were due to more nature, less technology or both. But they say extended periods in front of a computer likely has cognitive costs, and going for a hike could help reverse them. It may also be more crucial now than ever. Recent data show young people spend just 20 minutes a day playing outside and almost eight hours a day using cell phones, TVs and computers. So next time you are agonizing over your computer screen, consider stepping outside instead, and let nature nurture your mind. I am Dr. Holly Phillips.Task 1 Note-taking1) digital devices 2) in the great outdoors 3) mind 4) problem-solving abilities 5) creativity 6) cognitive 7) going for a hike 8) playing outside 9) using cell phones, TVs and computers 10) stepping outside and let nature nurture their mindTask 2 Dictation1) 56 2) 28 3) before 4) fourth 5) 4 6) 6Home Listening1) located 2) stimulate 3) components 4) previously 5) expand 6) challenge 7) stimulate your mind 8) mentally stimulating activities 9) helps decrease stress 10) positive and direct affectUnit3Transcript Lesson One Audio StudioClip 1 Made in ChinaAs we said somebody surprises in our important series made in China; your job, your future, your fortune. As you know our Bill Leer traveled more than 5000 miles across China to bring us an unprecedented look at all the different ways the country is affecting nearly every part of our lives this morning. And what every American worker needs to know about China,about their jobs is the subject of Bill’s. “Well we are in our Good Morning America bedroom this morning as many viewers of you are getting ready for your day here. Your day started thanks to China, because 80 percent of the clocks in this country are made in China.”“80 percent”“80 percent of the clocks are made in China. When the Chinese start dumping bedroom sets in America, a third of American wooden furniture manufacturers lost theirjobs. Chinese not only invented the toothbrush, they probably made yours, and your coffee maker and your towels. When they slashed sock prices a few years ago, a third of American sock manufacturers went out of business. And the shoes, these Nikes, brand-new, pretty nice, $74, right. The question is what would they cost if they were made in America So to find out and to find out how many other American jobs are in danger because of all this low price stuff. I followed this made-in-China label, 7000 miles right to the source.Task 1 Dictation1)surprises 2)series 3)fortune 4)more than 5000 miles 5)unprecedented 6)different 7)affecting 8)subjectTask 2 Note-taking1) 80 percent of the clocks in America are made in China 2) One-third of American wooden furniture manufacturers lost their jobs. 3) Chinese invented the toothbrush 4) One-third of American sock manufacturers went out of business. 5) Brand-new, pretty nice, $74, made in China.Clip 2 Breaking the “Bamboo Ceiling”When you think about, you know, sort of the factory innovation luxury, you end up with the brand like LiNing. Lining is sort of the Chinese Nike, as you can see, the Chinese AirJordan.LiNing is also a man, he is a China’s most famous Olympic athlete if you watched the Opening Ceremonies of the 2008 Olympic Games. You’ll remember him lighting the torch high above the stadium. You know what’s interesting is LiNing basically represents sort ofthe innovation and luxury model for China, which is basically brought in American designers. LiNing has tremendous name recognition already in China. He had support from the state. He has tremendous resources at his advantage, and basically he went up against Adidas and Nike, and in last year or so he has gotten crushed. He hit what some have called the bamboo ceiling. The idea that even Chinese consumers will not buy domestic brands when they have the opportunity to buy the foreign luxury brands. And so therefore LiNing is now struggling to reposition itself as more of a value commodity as something for people in the second and third tier cities, rather than as a luxury product. So it is easy, I think, for many of us to basically retreat into our default mindset, that once again China, excellent at manufacturing, excellent at efficiency, it can build the brand.Task 1 Note-taking1) the Chinese Nike and the Chinese Air Jordan. 2) lit the torch in the Opening Ceremony of the 2008 Olympic Games. 3) the sort of the innovation and luxury model for China 4) name recognition already 5) the state6) reposition himselfTask 2 Idea Box1) It refers to the idea that even Chinese consumers will not buy domestic brands when they have the opportunity to buy the foreign luxury brands. 2) open 3) openLesson Two Audio StudioClip 1 China Eyes Sophisticated Luxury GoodsAfter a market cultivating period since the end of last century to the beginning of this century, Chinese luxury goods market is gradually growing bigger, while western customers are tightening their belts as their economy remains mired in a sluggish recovery. The Chinesepublic’s appetite for high-end products has soared. China’s consumer luxury goods market isoutpacing every other luxury market in the world, with an estimated of growth of 23 percent in 2010. A rapidly expanding middle and upper class in China seek to enhance their identity and quality of life with luxury goods. Top-growth categories for luxury goods in China include: liquor (酒), fashion accessories and clothes, cars, jewelry and cosmetics. A report from theChinese Academy of Social Sciences says, “China will rank as the world’s largest market for luxury goods in 5 years’ time.” Over the past few years, China’s purchasing power for luxury goods has been growing at the pace of 20 percent annually. Right now, China’s largest groupof luxury goods consumers are between 20 and 30 yearsold, which means they have many consuming years still ahead of them, and the average age of Chinese high-end goods consumers is 15 years younger than the world average. As China becomes the fastest growing luxury goods market, it is not only attracting imported goods but western brands have also begun to design luxury goods to Chinese tastes. Experts say in the next 5 years, the Chinese luxury goods market will grow even larger.Task 1 Dictation1. cultivating2. luxury3. tightening their belts4. recovery5. appetite6. outpacing7. Estimated8.

After all, we are talking about a huge population with a growing economy, not to mention relative isolation from the social unrest, financial trauma and natural disasters that have disturbedthe world’s other major markets. But there is a deeper connection, luxury brands thrive herebecause they operate in both horizontal and vertical dimensions. In much of the west, taste is defined as a having unique personal style. Be yourself. Follow your instincts. Ugly can bebeautiful. Street style can be elegant. Under this framework, the only sin is insincerity. That’sa horizontal market, which is great for creativity, but not so great for luxury. China is different. Thousands of years of rigid society have left a deep mark. People here acknowledge the difference between low and high. So taste is not knowing yourself, it requires improving yourself. This is not about just showing face, which means tacky bling, sure that happens. Spending on luxury demonstrates your values, your culture, your virtue, your knowledge. This is the vertical dimension. Nobody understands this like the French. It is why Louie Vuitton knows to stake out the biggest, most lavish retail space in a mall. It is whycognac outsells whiskey, even at night clubs blasting hip-hop. We’re still at early phases here.After decades of austerity, China is rediscovering its imperial routes.

Transcript：JC: Well, gentlemen, let’s get started. I think we all know why we’re here, don’t we? The purpose of this meeting is to look into a recent incident which took place at the Shaftesbury Building in Tsim Sha Tsui, and to arrange for remedial work to be carried out by Kuen Wah. By the way, thank you for coming to the meeting, Mr. Koo. Now, perhaps, Harry, you’d better fill us all in on the details.JC: Do you have any photographs of the site of the incident?HF: Yes, we took photographs of the cooling tower damage, and I have them here with me.JC: Good, let’s have a look at them.HF: This photo shows that the external face of the cooling tower junction box has been badly burnt. I think this points to the fire having started outside the cooling tower rather than within. This next photo shows the condition of the controls and switchgears inside the cooling tower junction box. Look at how clean they are.JC: well, it certainly looks like the fire started outside. Lightning?HF: No, I don’t think so. The building is completely sheltered under the lightning-protection system, which is routinely checked and serviced, so I don’t think lightning is to blame.JC: Vandalism?HF: I personally think so.JC: Mmm. I tend to agree. Tougher security might stop such incidents happening again. Maybe some extra patrol points around the building perimeter and dead corners? Now, what about sorting the mess out? Mr. Koo, any suggestions?PK: Yes, well, the first thing to do is to repair the damage, and get rid of the burnt remains.JC: Can we fix a date for that now?PK: I see no reason why we cannot do that remedial work within the next week.JC: So, shall we say next Wednesday? That’s 4 May.PK: That sounds fine to me. Now, as far as our recommendations for ways to avoid this happening again, I really think the timber of the cooling towers should be protected with flame-retardant paint. That you may want to arrange with your general building contractor, although we’d be happy to help if we can.PK: You might also look at replacing your cooling towers with ADS-made cooling towers without timber parts. JC: Mmm. That’s a good idea, but that has to be seen as a long-term project. . . . Right, gentlemen, I think that about wraps up the meeting. Let me just recap. First, it looks like the most likely cause of the fire was vandalism, and that increased security may be needed to combat this in future. Second, Kuen Wah have agreed to carry out the necessary remedial work on Wednesday, 4 May, and have also offered to undertake repainting with flame-retardant paint. We’ll let you know about that. Lastly, the long-term solution to this may be the introduction of ADS-made cooling towers, and we shall put forward our recommendations to Senior Management about this. OK?Based on the transcript, please produce an effective minute of the meeting.Date: 26 April 2007Present: James Clark, Assistant Safety Manager （Osman Industries ）, Chairperson；Harry Fung, Inspection Engineer （Osman Industries）, Secretary；Peter Koo, MaintenanceEngineer（Kuen Wah Maintenance）；Minutes Recorder: Harry Fung.。

Especially, bionic contact lenses are being developed to provide a virtual display that could have a variety of uses from assisting the visually impaired to the video game industry. What ?s more, the lens will eventually have functional electronic circuits and infrared lights to create a virtual display.Slide 4 (Introduction):“The eye of the beholder ”The beginning of the Computer Human InterfaceIt would tell you what is relevant and what to ignoreTranslation between languages at any timeComputer Human InterfaceTime: 35 seconds (1:25-2:00) Say: In next 20 years, internet will be on our contact lens as the picture shows. Bionic contact lens is this kind of device that could give a new meaning to the phrase “The eye of the beholder”. It could be the beginning of the Computer Human Interface of the future and your smart lens would tell you what is relevant and what to ignore. In addition, if someone speaks in Chinese, no problem, Bionic contact lens will translate Chinese into English subtitles underneath your picture.Slide 5 (Body):1.Generation principleConvert pieces of plastic and polymer to a functional systemAntenna picks upradio frequencyenergyChip harveststhe energyTransform it intovoltage Transmitinformationdirectly on thelensTime: 40 seconds (2:00-2:40)Say:First of all, let's see how it works! Firstly, bionic contact lens converts pieces of plastic and polymer to a functional system that resemble a kind of complexity in cellular form, and antenna picks up radio frequency energy that is transmitted by an antenna elsewhere. Then, while chip harvests the energy and transforms it into voltage that can power the LED. Finally, voltage works to display directly on the lens that would transmit information directly on the lens.Slide 6 (Body):Time: 25 seconds (2:40-3:05)Say:Any advanced device has its core technology, including bionic contact lens. Bionic contact lens contains many of the most advanced technologies, such as capillary forces, Antenna, Chip, Fresnel lenses and so on. Among them, the core technology can be summarized as the following four aspects.Slide 7 (Body):Time: 50 seconds (3:05-3:55)Say:Next, let's look at the first aspect. Micro fabrication technique is used for image formation. We built the circuits from layers of metal only a few nanometers thick, about one thousandth the width of a human hair, and constructed light-emitting diodes one third of a millimeter across. Simultaneously, array of LED pixels is used in lens to form an active display. Therefore, the shape of each tiny component dictates which piece it can attach to, and a micro fabrication technique known as self-assembly.Slide 8 (Body):2)EnergyFirstly: Antenna picks up radiofrequency wavesThen: Turn them into energyFinally: Chip harvests the energyand transforms it into voltageTime: 40 seconds (3:55-4:35)Say:For the second aspect, Since this device is very small, the supply of energy is a key technical problem. As shown in this flowchart. Firstly, antenna picks up radio frequency waves and then turn them into energy that is transmitted by an antenna elsewhere. Finally, while chip harvests the energy and transforms it into voltage that can power the LED. The voltage is also a very small laser that can be used to ensure that the image is in focus at all times and eliminate the need for micro lenses.Slide 9 (Body):3) Virtual display technologyUsing a rasterdisplayDisplayed on theretina of the eyeVirtual Display ImageTime: 45 seconds (4:35-5:20)Say:Then, the third aspect is virtual display technology. A virtual retinal display, also known as a retinal scan display or retinal projector, is a display technology that draws a raster display directly onto the retina of the eye. In bionic lens, the display is floating in front of the user using virtual display technology. Certainly, it is not possible to display an image over a solid angle from a point source unless the projection system can bypass the lenses within the eye.Slide 10 (Body):4)Image technologyImage qualityFresnel lensesImage managementPixel managementTime: 60 seconds (5:20-6:20)Say:Finally, the core technology is to say that Image technology. It is mainly related to these four points on the slide. In terms of Image quality , we overcome that obstacle by precisely adjusting the angle of incoming light emitted by diodes on the contact lens. For Fresnel lenses and Image management, we tackled the limitation of the minimum focal distance of the human eye by incorporating a set of Fresnel lenses into the device. For Pixel management, we have provided the first proof-of-concept technology demonstrations for producing multipixel and in-focus images.Slide 11 (Body):Time: 45 seconds (6:20-7:05)Say:In the previous section, we have just talked about the generation of bionic contact lens and its core technology, then we talk about what are the critical applications. As shown on the slide, it consists mainly of six points. For example, zooming in on and out of distant objects- It means we would be able to zoom in on something far away or to look at something very close; And personalized wide-screen TV- It means the combination of contact lens with embedded optoelectronic and electronic devices could well be the beginning of the Computer Human Interface of the future. As time is limited, the following four points I will not explain in detail.Slide 12 (Body):Time: 40 seconds (7:05-7:45)Say:Although the application of good prospects for bionic contact lens, there are still several technical bottlenecks. Firstchallenge is how to attach the electronic components thinner than a human hair. The next problem is building the lenses is a challenge because materials that are safe for use in the body are delicate. What?s more, how to focus on image quality and how to give power supply are both the big obstacle. In addition to these points, there are other problems we need to work hard to resolve.Slide 13 (Conclusion):Time: 25 seconds (7:45-8:10)Say:As I end，the era of bionic contact lens would soon come. According to the introduction of the previous point of view, bionic contact lens with advanced core technology has a very good application prospects. However, there are still some bottlenecks to be resolved because of the technical problems so far.Slide 14 (Conclusion):Time: 35 seconds (8:10-8:45)Say:In short, bionic contact lens has a cross-era significance. One of the most important is bionic contact lens could be the beginning of the Computer Human Interface of the future when we could surf the Web at any time or keep the information connection all the time. Furthermore, a person could record their entire life just by blinking or possibly connect their contact lenses with a wireless device, and we would witness the day when everyone has the perfect vision.Slide 15 (Conclusion):Time: 15 seconds (8:45-9:00)Say:At the end of the report, I want to give a brief account of our future work. As shown here, we are based on the three main directions for further improvement of the bionic contact lens.Thank you. Are there any questions?。

PartIII.Killing Time
Mary Hollis, a market researcher talks to three customers in a supermarket queue: Stan Sorley, Judy Jameson and Alice Liddell.
Mary: Excuse me, would you mind answering some questions while you’re waiting?
Stan: Yeah, why not? It’s one way of killing the time. What about?
Mary: Actually, it’s exactly that. How do you kill the time in a supermarket queue? Um, have you got any special…sort of ..tips?
Stan: Funny, I’ve never thought much about it really. Oh yes, well, at the moment, you know, with Christmas coming and that, I think of the list of presents I’m going to buy, and the list of people I have to send card to, that kind of thing.
Mary: I see. And if it weren’t Christmas?
Stan: Er, yes, well, the other thing I do is add up the prices of what I buy, what I spend every week, on food and drink. You know, sort of ask myself how much I spend on my stomach every week. Oh yes, and a third thing is the I make comparisons, I compare pries now, say, with what I used to pay ten years ago.
Mary: Seems you’re very systematic. Thanks very much.
Stan: You’re welcome, dear
Mary: Excuse me, would you mind answering a question for some research we’re doing?
Judy: Ok
Mary: Er, what do you think about when you’re like this, waiting in the queue in a supermarket? Judy: Oh goodness!. Oh, let me think. Well, really, to tell you the honest truth, I’m a compulsive day-dreamer, so just now, for instance, I was trying to remember the most romantic evening I ever spent, with my husband of course, and trying to remember every detail of what we did and where we were wearing and so on, and I was just thinking that when I get back home tonight. I’m going to ask my husband if he remembers it? Men never do, you know, they’re hopeless, but still…Mary：That sounds nice. Any others? Any other day-dreams?
Judy: Oh yes, sometimes it’s what I would do with the money if my husband won a million on the football pools. And the other thing is wondering, well, suppose there was a famous star in the queue,, what would he be buying?
Mary: Thanks very much. Hope the dreams come true some day.
Judy: Thanks. Bye
Alice: Yes, I heard your question. I’m another memory person, I try and test my memory when I can, you know, because I’m getting on now, and I don’t want to start forgetting things…
Mary: They say if you don’t use it, you lose it, don’t they?
Alice: That’s it, so I try to remember things like, oh, the people I went to school with, my classmates, the teachers, the room, what we did, and so on. And another thing is I try to remember a particular group and try to see how much I know about their lives afterwards: who they married, how many children they had, what they did, where they lived and that king of thing.
Mary: That’s something I must try,. Do you try anything else?
Alice: Yes, I think of my family, reconstruct the family tree, with the names and the dates and all the different relationships, right back to the great-grandparents.
Mary: and when you’re not doing that?
Alice: The other thing I find myself doing a lot is just testing my memory, say, well, things like seeing if I can remember what I was dong a week ago, or a month ago, or reliving a moment in my
summer holiday.
Mar: Thanks very much.
Alice: A pleasure. Something to remember when I’m in the queue next week!。
