The freezing Northeast hasn't been a terribly fun place to spend time this winter, so when the chance came for a weekend to Sarasota, Florida, my bags were packed before you could say “sunshine”. I left for the land of warmth and vitamin C(维生素C), thinking of beaches and orange trees. When we touched down to blue skies and warm air, I sent up a small prayer of gratefulness. Swimming pools, wine tasting, and pink sunsets(at normal evening hours, not 4 in the afternoon) filled the weekend, but the best part - particularly to my taste, dulled by months of cold- weather root vegetables- was a 7 a.m. adventure to the Sarasota farmers' market that proved to be more than worth the early wake-up call.

           The market, which was founded in 1979, sets up its tents every Saturday from 7:00 am to 1 p.m., rain or shine, along North Lemon and State streets. Baskets of perfect red strawberries; the red-painted sides of the Java Dawg coffee truck; and most of all, the tomatoes: amazing, large, soft and round red tomatoes.

Disappointed by many a broken, vine-ripened(蔓上成熟的) promise, I've refused to buy winter tomatoes for years. No matter how attractive they look in the store, once I get them home they're unfailingly dry, hard, and tasteless. But I homed in, with uncertainty, on one particular table at the Brown's Grove Farm's stand, full of fresh and soft tomatoes the size of my fist. These were the real deal- and at that moment, I realized that the best part of Sarasota in winter was going to be eating things that back home in New York I wouldn't be experiencing again for months.

Delighted as I was by the tomatoes in sight, my happiness deepened when I learned that Brown's Grove Farm is one of the suppliers for Jack Dusty, a newly opened restaurant at the Sarasota Ritz Carlton, where - luckily for me - I was planning to have dinner that very night. Without even seeing the menu, I knew I'd be ordering every tomato on it.

    George Bernard Shaw，the greatest and funniest British dramatist(剧作家)of the first half of the 20th century，was born in Dublin，Ireland，on July 26,1856.His early life was not happy. His father was a selfish man who drank too much and could not support his family properly. His mother was a disappointed，unhappy woman who found more pleasure in studying music than in her children. Bernard and his two sisters received little love and attention from their mother while they were young. At the age of ten Shaw entered school. At first he was the best student，but soon he was at or near the bottom of his class.

    Although he did not like school，Bernard was a good，bright，curious student. His lifelong interest in everything from music and art to machines and medicine began from school life. The interests of this tireless schoolboy were literature and music. He often entertained(使快乐)his classmates with stories he read.

    Early at the age of fifteen，he went to work in an office. He did well as an office clerk，but after five years he decided that he wanted to be a writer. He left Ireland and went to London，where he began to write seriously. Seventy-four years later the great dramatist died.

    “Years ago when I was at the Grand Canyon, I remembered someone coming up to the canyon's edge, taking a shot with a camera and then walking away, like 'got it – done', barely even glancing at the magnificent scene in front of him,” Linda Henkel, a scientist at Fairfield University, US told Live Science.

    Henkel was surprised by how obsessed (痴迷的) people are with taking pictures these days - before dinner, during friends' birthday parties, on museum tours and so on.

    They keep taking pictures because they think that it helps record the moment, but as Henkel's latest study has just found out, this obsession may prevent their brains remembering what actually happened, reported The Guardian.

    In her study, Henkel led a group of college students around a museum and asked them to simply observe 15 objects and photograph 15 others. The next day the students' memory of the tour was tested, and the results showed that they were less accurate in recognizing the objects and they remembered fewer details about them if they photographed them.

    ''When people rely on technology to remember them — counting on the camera to record the event and thus not needing to attend to it fully themselves, it can have a negative impact on how well they remember their experiences,” Henkel explained.

    But there is also an exception: if students zoomed in to photograph part of an object, their memory actually improved, and those who focused the lens (镜头) on a specific area could even recall parts that weren't in the frame.

    So basically, this study is saying that constantly taking pictures can harm your memory. But shouldn't reviewing pictures we have taken help wake up our memories? This is true, but only if we spend enough time doing it.

    “In order to remember, we have to access and interact with the photos, rather than just collect them,” Henkel told The Telegraph. However, previous research has shown that most people never take the time to look over their digital pictures simply because there are too many of them and they aren't usually very organized on their computers.

    Anki has introduced Cozmo, a little robot powered by an advanced artificial intelligence. Cozmo promises to be for more interactive（互动的）than any toy robot.

Cozmo, which can lie in your hand, has a “brain”—technically its CPU—that can process data amazingly fast. In addition, Cozmo has a playful personality. He's designed to react to emotions and even ask users to play with him.

    Cozmo is not the first interactive toy to reach the market nor is it the first robot toy. What sets Cozmo apart from the other “smart toys” is that it has greater play value than those toys, which can become repetitious all too quickly.

    “Every interaction with Cozmo is different, so you do not put up with repetitive play patterns and responses typically found with other preprogrammed robots,” explained Anki spokesperson Peter Nguyen. Because it has functionality that is similar to that of video games, Cozmo also can receive regular updates, which could extend its playability. Still, Anki has designed this toy to be just that: a toy. It's not an advanced computerized robot. Its software is app-based.

    Cozmo lacks the “traditional” human-like robot form factor（要素）of legs, arms, and a head. But Cozmo does have an OLED screen/face with blue eyes, which in fact were designed to help it connect with its user.

    “I'm glad my kids are already raised,” said Roger L. Kay, analyst at Endpoint Technologies Associates. “Otherwise, they might become more antisocial if their relationship with Cozmo is more satisfying than those with real people,” said Kay. “Cozmo might encourage kids to learn more about technology or even inspire them to try programming and similar studies,” said Charles King, analyst at Pund-IT.

    Yet this technology does promise to be more than a toy. “It's a pretty cool invention and might have further applications, for example in elder care,” suggested Kay.

    People from East Asia tend to have more difficulty than those from Europe in distinguishing facial expressions — and a new report published online in Current Biology explains why.

    Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly(均匀的) across a face as Westerners do, Easterners fix their attention on the eyes.

    "We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and neglect (忽略) the mouth."

    According to Jack and her colleagues, the discovery shows that human communication of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to reliably convey emotion in cross-cultural situations.

    The researchers studied cultural differences in the recognition of facial expressions by recording the eye movements of 13 Western Caucasian and 13 East Asian people while they observed pictures of expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral. They compared how accurately participants read those facial expressions using their particular eye movement strategies.

    It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than Westerners did. "The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions," Jack said. "Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less."

    In short, the data show that facial expressions are not universal signals of human emotion. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.

Intelligence is traditionally viewed as the ability to think and learn. Yet in a complex world, there's another set of cognitive (认知的) skills that might matter more: the ability to rethink. Therefore, my aim in this book is to explore how rethinking happens by seeking out the most convincing evidence and some of the world's most skilled rethinkers.

The first section focuses on opening our own minds. You'll find out why a forward-thinking businessman got trapped in the past, how a Nobel Prize-winning scientist welcomes the joy of being wrong, how the world's best forecasters update their views, and how an Oscar-winning filmmaker has productive fights.

The second section examines how we can encourage other people to think again. You'll learn how an international debate champion wins arguments and an African-American musician persuades people to abandon discrimination (歧视). You'll discover how a special kind of listening helped an officer convince the opposing side to join in peace talks. And if you're a Yankees fan, I'm going to see if I can convince you to root for the Red Sox.

The third section is about how we can create communities of lifelong learners. In social life, a lab that specializes in difficult conversations will cast light on how we can communicate better about debated issues like climate change. In schools, you'll find out how educators teach kids to think again by treating classrooms like museums, and approaching projects like rewriting time-honored textbooks. I close by examining the importance of reconsidering our best-laid plans.

This book is an invitation to let go of knowledge and opinions that are no longer serving you well, and to establish your sense of self in flexibility rather than consistency. If you can master the art of rethinking, I believe you'll be better positioned for success at work and happiness in life. Thinking again can help you generate new solutions to old problems and revisit old solutions to new problems. It's a path to learning more from the people around you and living with fewer regrets.
