The forest in Senegal, a country in western Africa, is full of the chimps' usual noises. Suddenly dogs bark. Larger male chimps drop from the trees to face the threat while the others climb to safety. Then the dogs' young human masters appear.

One mother chimp with a tiny baby tries to run. The dogs attack and separate them. The two teenage boys quickly catch the baby chimp. But they don't act out of sympathy — they save the baby so they can sell it.

    After the teenagers return to their hometown, they visit a man who is said to be very interested in chimps. When they ask the man, Johnny Kante, if he wants to buy the baby, he replies, “That's not what we do.” Kante is a member of a scientific team. Although Kante is angry with the teens for capturing the chimp, he hides his anger and persuades them to take him to the baby chimp.

    Unsure of what to do next upon seeing the chimp, Kante calls Jill Pruetz, the head of the chimp research team. “I'm really worried,” says Pruetz, doubtful that the mother is still alive. But knowing that wild chimps sometimes adopt orphans（孤儿）， Kante and pruetz decide they must try to return the baby chimp to its wild community.

    Kante pays another visit to the teenagers. After he explains how much trouble they are in, because chimps are an endangered species, he requests they should give him the frightened baby without payment. They agree. Kante takes the baby chimp to his home and feeds her milk from a bottle whenever she cries.

    The next morning, Pruetz and Kante leave the baby with another team member and begin their search for the wild chimps. Pruetz quickly finds the group in the woods. She recognizes the female that is without her child.

    Pruetz is so excited that she runs the entire mile back to bring the baby chimp to the tree where the chimps are hanging out. The researchers place the baby on the ground near the tree and back away. Almost immediately, a male chimp drops to the ground and stares at the baby curiously. He carries her back to where the mother is waiting.

    Pruetz still can't believe how fortunate they were to have reunited the mother and child. “Surprising is the only word I can think of,” she says.

    It was the day after Halloween when my grandmother was admitted to the hospital with the worst headache she'd ever had. While posing in our costumes the night before, we knew something was wrong, just not how wrong.

    Grandma's house was the central gathering place of my family. Sunday lunches, birthday dinners, Easter, Thanksgiving, and Christmas — all were our traditions, with her as hostess. While my parents were busy running their small business, there were many nights when Grandma fed me and put me to bed in her spare room, until they came to get me. I spent my summers at Grandma's and I went everywhere with her. I couldn't imagine a time when she wouldn't be around me.

    Then November 1,1991 began her month-long stay in the hospital—she suffered from a rare infection (感染)called nocardia asteroides. After being born in the year of the Great Depression, living through World War II, raising three kids, and being widowed at the age of 48, Grandma never expected to live into her seventies. The infection in her brain seemed to confirm that she wasn't long for this world. But that's not the end of her story. A team of doctors successfully removed the abscess(脓肿), and Grandma even made it into a local medical journal. Her doctor called her “the brain lady”.

    Grandma celebrated her 85^th birthday in March this year. In the almost 23 years since her recovery, she's seen two of her four grandchildren get married and welcomed three great-grandsons. Although they damage something in her house, she loves it when my two boys come over. And while I know they make her day, seeing her love blossom for another generation makes my day too. Happy Grandparents' Day to my amazing grandmother!

    The human athlete has a special trick that no other animal has. It is called self-talk. Athletes talk to themselves to warm up, to focus and to help themselves believe they will win. A few simple words like “I can do it!” and “It is now or never!” can make the difference between winning gold or not.

    Self-talk is also used by speakers, actors and other performers. Before a speech, politicians believe that their words will win votes. And, self-talk helps students stay calm even when stumped by hard exam questions. Self-talk is a life skill you can use wherever you are, whenever you need it.

    The whole idea of talking to themselves seems strange to many people. Imagine your teacher saying, “For homework, talk to yourself for half an hour tonight.” You might think he is playing a joke on your class. Instead, adults teach kids all about talking to other people. There are many books on why, when, what and how to communicate with the rest of the world. Thus, you can grow up knowing a lot more about people around you than about yourself.

    It is good to speak and listen to others. But there is great value in making time to listen to yourself. When you do, you get to know yourself better. Along the way, you may discover the power you have for using words well.

    Such ideas are so exciting to psychologists that they have been trying to learn more about self-talk. In the study, people found certain lost items at home more easily when they talked to themselves while searching for the things.

    Baobab Tree Bar Wine Cellar, South Africa

    In the hollow (洞) of a huge 6,000-year-old baobab tree you can not only drink a cocktail, but also rest from the heat of Limpopo Province. Once this safe heaven was known only to the Bushmen, but now this ancient tree is the tourist destination for all kinds of tourists.

    The Birdsville Hotel and Pub, Australia

    At the edge of the Simpson Desert, among the sand dunes (沙丘), which are the favorite spot for the mice, there is a hotel and a pub. The walls of this bar are decorated with old hats and posters of beer, the oldest of which dates from 1884. Most visitors of this building are the amateurs of racing. They come to this village for the September competition. However, the pub is not empty also on other months: the airstrip (飞机跑道) is located nearby, so those who get off the plane are going to have a glass or two of beer first.

    What to order: a pint of beer.

    Floyd's Pelican Bar, Jamaica

    It appears that these huge palm leaves and trunks fell into the ocean long time ago. They floated on the waves and then piled up year by year, sticking out of the ocean. That's probably how the Pelican Bar, located about a mile from the southwest coast of Jamaica, is built on. Some of its visitors have no room to be fitted inside the bar, and they just drink standing in waist-deep water.

    What to order: cocktail “Pelican Perfection”.

    Robots make me nervous — especially the ones which seem to think for themselves. I was embarrassed to admit this till I heard that Bill Gates, the founder of Microsoft, felt the same way.

Gates said in an interview with the social networking and news website Reddit: "I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage well. A few decades after that though the intelligence is strong enough to be a concern."

    Well, maybe I don't have to worry about my computer and kitchen equipment yet. After I use them I can always pull the plug. But in the future, machines might find a way to prevent us from switching them off. There's a terrible thought!

    Maybe the problem with computers too clever for us is not that they are evil like some we've seen in sci-fi movies. What could put us in danger is that they might be too efficient. That's what philosopher Nick Bostrom from Oxford University believes. He says that machines are indifferent to humans and in pursuit of their own goals, the destruction of people might be just additional damage. Bostrom gives us an example: A machine which might have as its only goal to produce as many paperclips as possible might look at human bodies as extra material for paperclips and go after you. Because it is, well, a machine, it would not take pity on you.

    It's a good thing that American writer Isaac Asimov thought about how far robots can go and left us his three rules of robotics. They state that a robot may not hurt a human being or allow the human being to come to harm.

I'm glad my machines at home are "dumb". All my cleaner wants to take over is the carpet in my living room. Let's hope they don't create an appliance which wants to take over the world!

    In university I had a part-time job at a shop that sold doughnuts and coffee. Situated on a block where several buses stopped, it served the people who had a few minutes to wait for their bus.

    Every afternoon around four o'clock, a group of schoolchildren would burst into the shop, and business would come to a stop. Adults would glance in, see the crowd and pass on. But I didn't mind if the children waited for their bus inside. Sometimes I would hand out a bus fare when a ticket went missing — always repaid the next day. On snowy days I would give away some doughnuts. I would lock the door at closing time, and we waited in the warm shop until their bus finally arrived.

    I enjoyed my young friends, but it never occurred to me that I played an important role in their lives — until one afternoon when a man came and asked if I was the girl working on weekdays around four o'clock. He identified himself as the father of two of my favorites.

    "I want you to know I appreciate what you do for my children. I worry about them taking two buses to get home. It means a lot that they can wait here and you keep an eye on them. When they are with the doughnut lady, I know they are safe." I told him it wasn't a big deal, and that I enjoyed the kids.

    So I was the Doughnut Lady. I not only received a title, but became a landmark.

    Now I think about all the people who keep an eye on my own children. They become, well, Doughnut Ladies. Like the men at the skating rink (滑冰场) who let my boys ring home; Or the bus driver who drove my daughter to her stop at the end of the route at night but wouldn't leave until I arrived to pick her up; Or that nice police officer who took pity on my boys walking home in the rain when I was at work — even though the phone rang all the next day with calls from curious neighbors. "Was that a police car I saw at your house last night?"

    That wasn't a police car. That was a Doughnut Lady.
