Answer the questions by marking the corresponding letter on Answer Sheet 2.The Blessing and Curse of the People Who Never ForgetA handful of people can recall almost every day of their lives in enormous detail—and after years of research, neuroscientists (神经科学专家) are finally beginning to understand how they do it.[A] For most of us, memory is a mess of blurred and faded pictures of our lives. As much as we would like to cling on to our past, even the saddest moments can be washed away with time.[B] Ask Nima Veiseh what he was doing for any day in the past 15 years, however, and he will give you the details of the weather, what he was wearing, or even what side of the train he was sitting on his journey to work. “My memory is like a library of video tapes, walk-throughs of every day of my life from waking to sleeping,” he explains.[C] Veiseh can even put a date on when those tapes started recording: 15 December 2000, when he met his first girlfriend at his best friend's 16th birthday party. He had always had a good memory, but the thrill of young love seems to have shifted a gear in his mind: from now on, he would start recording his whole life in detail. “I could tell you everything about every day after that.”[D] Needless to say, people like Veiseh are of great interest to neuroscientists hoping to understand the way the brain records our lives. A couple of recent papers have finally opened a window on these people’s extraordinary minds. And such research might even suggest ways for us all to relive our past with greater clarity.[E] “Highly superior autobiographical memory”(or HSAM for short) first came to light in the early 2000s, with a young woman named Jill Price. Emailing the neuroscientist and memory researcher Jim McGaugh one day, she claimed that she could recall every day of her life since the age of 12. Could he help explain her experiences?[F] McGaugh invited her to his lab, and began to test her: he would give her a date and ask her to tell him about the world events on that day. True to her word, she was correct almost every time.[G] It didn’t take long for magazines and documentary film-makers to come to understand her “total recall”, and thank to the subsequent media interest, a few dozen other subjects (including Veiseh) have since come forward and contacted the team at the University of California, Irvine.[H] Interestingly, their memories are highly self-centred: although they can remember “autobiographical” life events in extraordinary detail, they seem to be no better than average at recalling impersonal information, such as random (任意选取的)lists of words. Nor are they necessarily better at remembering a round of drinks, say. And although their memories are vast, they are still likely to suffer from “false memories”.Clearly, there is no such thing as a “perfect” memory—their extraordinary minds are still using the same flawed tools that the rest of us rely on. The question is, how?[I] Lawrence Patihis at the University of Southern Mississippi recently studied around 20 people with HSAM and found that they scored particularly high on two measures: fantasy proneness (倾向)and absorption. Fantasy proneness could be considered a tendency to imagine and daydream, whereas absorption is the tendency to allow your mind to become fully absorbed in an activity to pay complete attention to the sensations (感受)and the experiences. “I’m extremely sensitive to sounds, smells and visual detail,” explains Nicole Donohue, who has taken part in many of these studies. “I definitely feel things more strongly than the average person.”[J] The absorption helps them to establish strong foundations for recollection, says Patihis, and the fantasy proneness means that they revisit those memories again and again in the coming weeks and months. Each time this initial memory trace is “replayed”, it becomes even stronger. In some ways, you probably go through that process after a big event like your wedding day,but the difference is that thanks to their other psychological tendencies, the HSAM subjects are doing it day in, day out, for the whole of their lives.[K] Not everyone with a tendency to fantasise will develop HSAM, though, so Patihis suggests that something must have caused them to think so much about their past. “Maybe some experience in their childhood meant that they became obsessed (着迷)with calendars and what happened to them,”says Patihis.[L] The people with HSAM I’ve interviewed would certainly agree that it can be a mixed blessing. On the plus side, it allows you to relive the most transformative and enriching experiences. Veiseh, for instance, travelled a lot in his youth. In his spare time,he visited the local art galleries, and the paintings are now lodged deep in his autobiographical memories.[M] “Imagine being able to remember every painting, on every wall, in every gallery space, between nearly 40 countries,” he says. “That’s a big education in art by itself.” With this comprehensive knowledge of the history of art, he has since become a professional painter.[N] Donohue, now a history teacher, agrees that it helped during certain parts of her education. “I can definitely remember what I learned on certain days at school. I could imagine what the teacher was saying or what it looked like in the book.”[O] Not everyone with HSAM has experienced these benefits, however. Viewing the past in high definition can make it very difficult to get over pain and regret. “It can be very hard to forget embarrassing moments,” says Donohue. “You feel the same emotions—it is just as raw, just as fresh... You can’t turn off that stream of memories, no matter how hard you try.” Veiseh agrees. “It is like having these open wounds—they are just a part of you,” he says.[P] This means they often have to make a special effort to lay the past to rest. Bill, for instance, often gets painful “flashbacks”,in which unwanted memories intrude into his consciousness, but overall he has chosen to see it as the best way of avoiding repeating the same mistakes. “Some people are absorbed in the past but not open to new memories, but that’s not the case for me. I look forward to each day and experiencing something new.”1.People with HSAM have the same memory as ordinary people when it comes to impersonal informatio.2.Fantasy proneness will not necessarily cause people to develop HSAM.3.Veiseh began to remember the details of his everyday experiences after he met his first young love.4.Many more people with HSAM started to contact researchers due to the mass media.5.People with HSAM often have to make efforts to avoid focusing on the past.6.Most people do not have clear memories of past events.7.HSAM can be both a curse and a blessing.8.A young woman sought explanation from a brain scientist when she noticed her unusual memory.9.Some people with HSAM find it very hard to get rid of unpleasant memories.10.A recent study of people with HSAM reveals that they are liable to fantasy and full absorption in an activity.

Answer the questions by marking the corresponding letter on Answer Sheet 2.From Accountant to Yogi: Making a Radical Career Change[A] At some point, almost all of us will experience a period of radical professional change. Some of us will seek it out; for others it will feel like an unwelcome intrusion into otherwise stable careers. Either way, we have choices about how we respond to it when it comes.[B] We recently caught up with yoga entrepreneur Leah Zaccaria, who put herself through the fire of change to completely reinvent herself. In her search to live a life of purpose, Leah left her high-paying accounting job, her husband, and her home, hi the process, she built a radically new life and career. Since then, she has founded two yoga studios, met a new life partner, and formed a new community of people. Even if your personal reinvention is less drastic, we think there are lessons from her experience that apply.[C] Where do the seeds of change come from? the Native American Indians have a saying: “Pay attention to the whispers so you won’t have to hear the screams.” Often the best ideas for big changes come from unexpected places — it’s just a matter of tuning in. Great leaders recognize the weak signals or slight signs that point to big changes to come. Leah reflects on a time she listened to the whispers: “About the time my daughter was five years old. I started having a sense that ‘this isn’t right.”’ She then realized that her life no longer matched her vision for it.[D] Up until that point, Leah had followed traditional measures of success. After graduating with a degree in business and accounting, she joined a public accounting firm, married, bought a house, put lots of stuff in it, and had a baby. “I did what everybody else thought looked successful,” she says. Leah easily could have fallen into a trap of feeling content; instead, her energy sparked a period of experimentation and renewal.[E] Feeling the need to change, Leah started playing with future possibilities by exploring her interests and developing new capabilities. First trying physical exercise and dieting, she lost some weight and discovered an inner strength. “1 felt powerful because 1 broke through my own limitations,” she recalls.[F] However, it was another interest that led Leah to radically reinvent herself. “I remember sitting on a bench with my aunt at a yoga studio,’’ she said, having a moment of clarity right then and there: Yoga is saving my life. Yoga is waking me up. I’m not happy and I want to change and I’m done with this.” In that moment of clarity Leah made an important leap,conquering her inner resistance to change and making a firm commitment to take bigger steps.[G] Creating the future you want is a lot easier if you are ready to exploit the opportunities that come your way. When Leah made the commitment to change, she primed herself to new opportunities she may otherwise have overlooked. She recalls:[H] One day a man I worked with, Ryan, who had his office next to mine, said, “Leah, let’s go look at this space on Queen Anne.” He knew my love for yoga and had seen a space close to where he lived that he thought might be good to serve as a yoga studio. As soon as I saw the location, I knew this was it. Of course I was scared, yet I had this strong sense of “I have to do this.” Only a few months later Leah opened her first yoga studio, but success was not instant.[I] Creating the future takes time. That’s why leaders continue to manage the present while building toward the big changes of the future. When it’s time to make the leap, they take action and immediately drop what’s no longer serving their purpose. Initially Leah stayed with her accounting job while starting up the yoga studio to make it all work.[J] Soon after, she knew she had to make a bold move to fully commit to her new future. Within two years, Leah shed the safety of her accounting job and made the switch complete. Such drastic change is not easy.[K] Steering through change and facing obstacles brings us face to face with our fears. Leah reflects on one incident that triggered her fears, when her investors threatened to shut her down: “I was probably up against the most fear I’ve ever had,” she says. “I had spent two years cultivating this community, and it had become successful very fast, but within six months I was facing the prospect of losing it all.”[L] She connected with her sense of purpose and dug deep, cultivating a tremendous sense of strength. “I was feeling so intentional and strong that I wasn’t going to let fear just take over. I was thinking, ‘OK, guys, if you want to try to shut me down, shut me down.’And I knew it was a negotiation scheme, so I was able to say to myself, ‘This is not real.’” By naming her fears and facing them head-on, Leah gained confidence. For most of us, letting go of the safety and security of the past gives us great fear. Calling out our fears explicitly, as Leah did,can help us act decisively.[M] The cycle of renewal never ends. Leah’s growth spurred her to open her second studio— and it wasn’t for the money.[N] I have no desire to make millions of dollars. It’s not about that; it’s about growth for me. Honestly, I didn’t need to open a second studio. I was making as much money as I was as an accountant. But I know if you don’t grow, you stand still, and that doesn’t work for me.[O] Consider the current moment in your own life, your team or your organization. Where are you in the cycle of renewal: Are you actively preserving the present, or selectively forgetting the past, or boldly creating the future? What advice would Leah give you to move you ahead on your journey? Once we’re on the path of growth, we can continually move through the seasons of transformation and renewal.1. Readiness to take advantage of new opportunities will make it easier to create one’s desired future.2. By conventional standards, Leah was a typical successful woman before she changed her career.3. Leah gained confidence by laying out her fears and confronting them directly.4. In search of a meaningful life, Leah gave up what she had and set up her own yoga studios.5.Leah's interest in yoga prompted her to make a firm decision to reshape her life.6. Small signs may indicate great changes to come and therefore merit attention.7. Leah’s first yoga studio was by no means an immediate success.8. Some people regard professional change as an unpleasant experience that disturbs their stable careers.9. The worst fear Leah ever had was the prospect of losing her yoga business.10. As she explored new interests and developed new potentials,Leah felt powerful internally.
