In 1974, after filling out fifty applications, going through four interviews, and winning one offer, I took what I could get —- a teaching job at what I considered a distant wild area: western New Jersey. My characteristic optimism was alive only when I reminded myself that I would be doing what I had wanted to do since I was fourteen —— teaching English.

    School started, but I felt more and more as if I were in a foreign country. Was this rural area really New Jersey? My students took a week off when hunting season began. I was told they were also frequently absent in late October to help their fathers make hay on the farms. I was a young woman from New York City, who thought that “Make hay while the sun shines” just meant to have a good time.

But, still, I was teaching English. I worked hard, taking time off only to eat and sleep. And then there was my sixth-grade class — seventeen boys and five girls who were only six years younger than me. I had a problem long before I knew it. I was struggling in my work as a young idealistic teacher. I wanted to make literature come alive and to promote a love of the written word. The students wanted to throw spitballs and whisper dirty words in the back of the room.

    In college I had been taught that a successful educator should ignore bad behavior. So I did, confident that, as the textbook had said, the bad behavior would disappear as I gave my students positive attention. It sounds reasonable, but the text evidently ignored the fact that humans, particularly teenagers, rarely seems reasonable. By the time my boss, who was also my taskmaster, known to be the strictest, most demanding, most quick to fire inexperienced teachers, came into the classroom to observe me, the students exhibited very little good behavior to praise.

    My boss sat in the back of the room. The boys in the class were making animal noises, hitting each other while the girls filed their nails or read magazines. I just pretended it all wasn't happening, and went on lecturing and tried to ask some inspiring questions. My boss, sitting in the back of the classroom, seemed to be growing bigger and bigger. After twenty minutes he left, silently. Visions of unemployment marched before my eyes.

    I felt mildly victorious that I got through the rest of class without crying, but at my next free period I had to face him. I wondered if he would let me finish out the day. I walked to his office, took a deep breath, and opened the door.

He was sitting in his chair, and he looked at me long and hard. I said nothing. All I could think of was that I was not an English teacher; I had been lying to myself, pretending that everything was fine.

    When he spoke, he said simply, without accusation, “You had nothing to say to them.”

     “You had nothing to say to them”. he repeated.” No wonder they are bored. Why not get to the meat of literature and stop talking about symbolism. Talk with them, not at them. And more important, why do you ignore their bad behavior”? We talked. He named my problems and offered solutions. We role-played. He was the bad student, and I was the forceful, yet, warm, teacher. 
       As the year progressed, we spent many hours discussing literature and ideas about human beings and their motivations. He helped me identify my weaknesses and strengths. In short, he made a teacher of me by teaching me the reality of Emerson's words: “The secret to education lies in respecting the pupil.”

    Fifteen years later I still drive that same winding road to the same school. Thanks to the help I received that difficult first year, the school is my home now.

    Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.

    The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.

    Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.

    But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.

    There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.

    If you are a recent social science graduate who has had to listen to jokes about unemployment from your computer major classmates, you may have had the last laugh. There are many advantages for the social science major because this high-tech "Information Age" demands people who are flexible (灵活) and who have good communication skills.

    There are many social science majors in large companies who fill important positions. For example, a number of research studies found that social science majors had achieved greater managerial success than those who had technical training or pre-professional courses. Studies show that social science majors are most suited for change, which is the leading feature (特点) of the kind of high-speed, high-pressure, high-tech world we now live in.

    Social science majors are not only experiencing success in their long term company jobs, but they are also finding jobs more easily. A study showed that many companies had filled a large percentage of their entry level positions with social science graduates. The study also showed that the most sought-after quality in a person who was looking for a job was communication skills, noted as "very important" by 92 percent of the companies. Social science majors have these skills, often without knowing how important they are. It is probably due to these skills that they have been offered a wide variety of positions.

    Finally, although some social science majors may still find it more difficult than their technically trained classmates to land the first job, recent graduates report that they don't regret their choice of study.

    Computers have beaten human world champions at chess and, earlier this year, the board game Go(围棋). So far, though, they have struggled at the card table. So we challenged one AI(artificial intelligence) to a game.

Why is poker so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an “information incomplete” game. Players have to guess opponents' hands from their actions—-tricky for computers. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

    Scientists believe it is only a matter of time before AI once again vanquishes humans, so our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, a researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

    Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

    Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

    After two hours of quite defensive play, from the computer at least, we called it a draw.

    Dutch beachcomber (海滩拾荒者) Wim Kruiswijk has accumulated a collection of 1,200 messages-in-bottles over the course of nearly 4 decades and has responded to almost all of them,

    68-year-old Kruiswijk says that his unusual hobby began in 1983 when he found three drift bottles (漂流瓶) on his local beach, each containing letters and return addresses. He wrote to all three addresses and was surprised to receive responses from each one. It was this experience that aroused his interest in hunting and collecting messages in bottles, and he hasn't stopped looking for them since.

"I find my messages in bottles on the beach of Zandvoort, where I live, and on the Dutch Islands," Kruiswijk recently told Great Big Story. "Messages in bottles is slow mail. It takes you days, or weeks, or months to find a bottle. "

In the early years, Kruiswijk would find as many as 50 bottles a year, but since 2000 that has slowed to around 20-30 finds, mainly due to beach cleaning efforts. He believes that the rise of the Internet has also played a role in the diminishing number of messages in bottles, telling Dutch newssite PZC, "I used to get a response at half the bottle messages that I answered. Now that's less; many people want 'instant satisfaction'."

    Throwing a message in a bottle out into the sea is a longstanding human tradition dating back to the time of the Greek philosopher Theophrastus, about 310 BC，who used the bottles to study water currents. Scientists still apply the method to this day, as a means to help researchers develop ocean circulation maps, and to crowdsource scientific studies of ocean currents.

    In the past bottles have also been used to send distress messages from sailors in trouble. They also have been used for memorial tributes, or to send loved ones' ashes on a final journey. One of the more common uses though is just to send invitations out to prospective pen pals, a quaint notion in these modern times, but, as Kruiswijk so clearly shows, an effective one.
