When Johnnie Martin was in the second grade in high school, one day a psychologist of the school called him into his office.

    “Johnnie, I've made a very careful study of you. And I feel sorry to have to tell you… Though you have worked very hard, it has not helped. You're just not fit for it.”

    The boy buried his face in his hands, “This will be hard on my parents,” he said. “Their one idea is for me to be a college man.”

    The psychologist laid his hand on the boy's shoulder and said, “People have different kinds of talents. Some day you will find what your special gift is and when you do, you will make your parents very proud of you.”

    Johnnie never went back to school. Jobs were scarce in town, but he managed to keep busy mowing the lawns of the householders and puttering in their flowerbeds. Before long he discovered he had an eye for color.

    One day while he was downtown, he happened to notice a stretch of unused land behind the city hall. Chance or fate or whatever you may like to call it brought one of the town's aldermen（市政委员会委员）round the corner just at that moment. The boy said, “I can make a garden out of this dump, if you'll let me do it.”

    “The town's got no money for it,” said the alderman.

    “I don't want any money for it,” said the boy. “I just want to do it.”

    The alderman was shocked to find someone who did not want money. He took Johnnie into an office, and when the young man came out he had the authority to clean up the public eyesore. Before long the old dump became a little beautiful park.

    It was also a kind of show window for Johnnie. People saw the result of his skill and knew him as a natural landscape gardener.

    That was twenty-five years ago. Today Johnnie is the head of a successful business in landscape gardening. His aging parents are proud of Johnnie, for he is not only a success, but he has also made his part of the world a lovelier place to live in.

    Who is smarter? A human being or artificial intelligence?

The question swept the world last week when a Google-developed program called AlphaGo defeated the world top player, South Korean Lee Se-dol, 4-1.

    So, what comes next?

    Some people have been arguing that artificial intelligence, or AI in short, will be a bad thing for humans. In an interview with the BBC in 2014, UK scientist Stephen Hawking warned that “The development of full artificial intelligence could mean the end of the human race.”

    So are we really about to live in the world shown in the Terminator movies?

    “Not quite,” answered The Economist. After all, it's not hard to get a computer program to remember and produce facts. What is hard is getting computers to use their knowledge in everyday situations.

    “We think that, for the human being, things like sight and balance(视觉平衡), are natural and ordinary in our life.” Thomas Edison, founder of Motion Figures, a company that is bringing AI to boys, told the newspaper. “But for a robot, to walk up and down just like human beings requires various decisions to be made every second, and it's really difficult to do.”

    As The Economist put it, “We have a long way to go before AI can truly begin to be similar to the human brain, even though the technology can be great.”

    Meanwhile, John Mark off of The New York Times said that researchers should build artificial intelligence to make people more effective.

    “Our fate is in our own hands,” he wrote. “Since technology depends on the values of its creators, we can make human choices that use technology to improve the world.”

    I travel a lot, and I find out different "styles"(风格）of directions every time I ask "How can I get to the post office?"

    Foreign tourists(游客) are often confused(困惑)in Japan because most streets there don't have names; in Japan, people use landmarks(地标)in their directions instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop."

    In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east, and then go another mile."

    People in Los Angeles , California, have no idea of distance on the map; they measure(度量) distance in time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it' is about five minutes from here." You say, "Yes, but how many miles away is it ?"They don't know.

    It's true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." People in Yucatan believe that "I don't know" is impolite. They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!

    The sun was shining and Clare felt like doing something active. She'd had enough of the moment of living in the past. What she really wanted was some skiing if she could get herself organized. She walked into the ski school office and within ten minutes had arranged a private class for the whole afternoon. One of the ski teacher would meet her at the ski lift station at the end of the village at midday. The ski hire shop next door rented her some skis and boots and she carried them back to the hotel. There she changed into some more or less suitable clothes and took the hotel's electric taxi down to the lift station. She was a bit early and had time to look around, and get nervous. She hadn't skied for about ten years, though she'd been quite good at that time. Everyone said it was liking riding a bike-you didn't forget how to do it. She stood there looking up at the mountains, trying to remember what to do.

    Madam Newton?" Yes," she said. And there was her ski teacher, looking exactly like all the other ski teachers she remembered sun-tanned, handsome and totally self-confident. Half an hour later all thoughts of the unhappy days had disappeared as she skied behind Bruno and concentrated on staying on her feet.

    "Upper body still, make your legs do the work, Madame", shouted Bruno over his shoulder. "Call me Clare, please" she said. "OK. Lean forward a bit more, Clare. That's it. Good. You are remembering now, en?" "Yeah, I am ... slowly. It's great. I'd forgotten what an amazing buzz skiing gives you".

    They skied down some different runs with Bruno being wonderfully encouraging, and she really did begin to feel confident on the skis. Going up in the lifts, Clare and Bruno chatted — just the usual "where are you from, what do you do" sort of chat, but it was pleasantly relaxing. In the middle of the afternoon, they stopped at an old farmhouse for coffee and apple cake. There were lots of other skiers doing the same. Clare felt as if she belonged - something about being part of a group, all with a shared interest, she supposed. It was a feeling she'd not had for a long time.

    Bruno said hello to a few people, and went over to talk to one of the waiters. Clare took the opportunity to study him a bit. Up until now, she'd just been skiing behind a man in a red ski suit, so it was interesting to see that he was quite tall, with curly brown hair and eyes to match. From the colour of his face he looked as if he'd spent his whole life in the open air. She guessed he was about forty.

    "Are you in Zermatt for long, Clare?" asked Bruno, after he'd been sitting with her a few minutes, "No, only a few days probably. Just a short break to get away from everything at home", replied Clare. She didn't feel like explaining the real reason. People looked at her differently when they knew. "But I'd like to do some more skiing. Would you be able to do anything tomorrow?"

    "I think so. But you'll have to book it through the ski school office. I can't arrange anything with you directly", said Bruno, putting on his gloves and standing up. "Come on. Let's do a bit more now." "Great," replied Clare. After another hour, Clare said, "Time to stop, I think," Bruno agreed. "You should have a sauna tonight. It'll help your body relax. Not so stiff (僵硬的）tomorrow, you know." Clare didn't care about stiff she was going to be tomorrow. She hadn't felt quite as good as this for months — full of fresh air, physically tired but in her mind — alive. Happy! Yes, that was how she felt.

Bergl doesn't consider himself the next Thomas Edison, He's just a man loving animals, Africa and adventure, Yet, Bergl might have invented a tool as great as the light bulb (灯泡) ―a tool that uses modern-day technology to solve an almost prehistoric (史前) problem.

The tool is called the SMART. It is designed to be waterproof (防水的) , shockproof and poacher (偷猎者) proof. Bergl worked with worldwide wildlife groups to develop it in 2011. Since then it has been seen in more than 55 countries where poachers have forced the best-known but most endangered animals to nearly die out .

SMART works as a very simple smart phone―it lets the user record what they see, like animal sightings. changes in animals and illegal activities If a park ranger (管理员) sees something that is very important, that information can be sent to the cloud (云) and sent out to the base camp so they can take action and stop the killing 

Bergl and his workmates travel to African wildlife reserves now and then They teach park rangers in some of the most remote countries how to use SMART. "SMART makes collection of information easier It allows us to pay attention to the things that really important. according to what the information is telling an,"Aid Skim Young, manager of the Etosha National park in Namibia, "thanks to SMART, most of Africa's endangered animals seem to be coming back." 

Bergl never plans to make money from his small but great invention. SMART is free and doesn't even have a patents(专利).
