A new study finds that young females in one group of African chimps(黑猩猩) use sticks as dolls more than their male peers (同龄) do, often treating pieces of wood like a mother chimp caring for a baby. In human cultures around the world, girls play with dolls and pretend that the toys are babies far more than boys do.

    Chimp observations, collected over 14 years of field work with the Kanyawara chimp community in Kibale National Park in Ugandan, provide the first evidence of a nonhuman animal in the wild that exhibits sex differences in how it plays. This finding supports an argument that biology as well as society underlies boys' and girls' different toy preferences.

    Stick play occurred most commonly between ages 3 and 9. Females spent a lot more time carrying sticks than males did. Young male chimps occasionally used sticks to mimic(模仿) childcare. "Far more often, they fought with sticks, an infrequent behavior among females," say Sonya Kahlenberg of Bates College in Lewiston, Maine, and Richard Wrangham of Harvard University.

    "Biological differences between the sexes make female chimps more receptive to stick-mothering than males," says Wrangham.

    Consistent with reported cultural traditions among adult chimps, Kanyawara youngsters learned from each other to play with sticks as if caring for babies. Stick play among young chimps showed no evidence of being directly influenced by older chimps. Child-bearing females never played with sticks and thus didn't model such behavior for younger chimps.

    Young females carried sticks for anywhere from a few minutes to several hours. They often rested in nests with their sticks, sometimes playing with them much as chimp mothers play with their babies though they didn't get any form of teaching from the adults.

    I grew up in a troubled home in the 1970s, on the outskirts of downtown Orlando, Florida. Not far away, a three-story house attracted my eyes.

    It was nothing like the one I lived in with my mother, a small dark place with rules about befriending others. “Don't. Never, ever talk to anyone,” my mother said.

    One day, in sixth grade, a black-haired woman was introduced to our class: Mrs. Reese. Reese explained that she was starting Spanish Club. She invited anyone interested in learning Spanish language and culture to stay after school.

    I could not take my eyes off her bracelets(手镯) and shining rings. The bell rang, and to my shock, no one went up to Mrs. Reese. I was under strict orders to go straight home. But that day, I stayed. I asked Mrs. Reese when the club started.

    “We could begin right now if you like,” she said with a smile. I felt beautiful. That day I learned that the house of my dreams was her house. I learned how to answer questions about my age and my favorite food in Spanish. And I learned, “Do you want to come over tomorrow for cooking lessons?”

    I wanted to say “Yes”, but Mom's words held me back.

I begged my mother all summer and into fall, well after Spanish Club had dissolved. I wept at night sometimes, so worried that Mrs. Reese and her family would move away.

    At some point, I managed to wear my mother down and one Saturday afternoon. I rode out to Mrs. Reese's house.

    The details of that afternoon are marked in my mind: We had tea. She painted my toenails red. We made a garlicky picadillo. We spoke in Spanish. In Spanish, my voice was loud and romantic. This is the real me! I remember thinking.

    My mother never permitted me another visit to Mrs. Reese's house. But four decades later, I still remember that day and the life she showed me, proof of a possible future.

Dear Anne,

    I like your column very much. I met a girl four years ago at a gym. She was the one who originally approached me and we became good friends. Then one day, she made me really angry, so angry that I just left and we never saw each other again.

    Looking back, I really regret ending things that way. It was a cowardly act on my part, but I had a terrible temper at that time and let the smallest thing get to me. Recently, I've started thinking about her again and I looked up her e-mail address. I thought about writing to say “Hi” and apologize for what I did but I'm not sure. She could still be angry with me, or maybe she has forgotten me. I feel very lonely and I want to see her again. What should I do?

Tom

Dear Tom,

    She may still be angry with you, and she may have forgotten the friendship between you, but that doesn't mean she doesn't deserve an apology. Tom, how many of us have wished for the day that someone who treated us badly saw the light and finally owned up? But we rarely get that kind of expected result. So sure, e-mail her and say “Hi”.

    Tell her you have been thinking about her and just want to apologize for getting angry and being a coward by walking out on her. But you should remember if she thinks you're apologizing just because you are lonely, she might dismiss your sincerity. Therefore, don't mention that. If she wants to see you again, she'll make sure that happens.

    Even if she doesn't want to be your friend, I can assure you, she'll appreciate the gesture. And it might make you think twice next time you get angry.

    A Canadian woman who lost her diamond ring 13 years ago while cleaning her garden on the family farm is wearing it proudly again after her daughter-in-law pulled it from the ground or a carrot.

    Mary Grams, 84, said she can't believe the lucky carrot actually grew through and around the diamond ring she had long given up hope of finding. She said she never told her husband, Norman, that she lost the ring, but only told her son. Her husband died five years ago.

    “I feel glad and happy, ”Grams said this week . “I grew into the carrot. I feel it amazing”,

    Her daughter-in-law, Calleen Daley, found the ring while getting carrots in for supper with her dog Billy at the farm near Armena, Alberta, where Grams used to live. The farm has been in the family for 105 years. Daley said while she was pulling the carrots and noticed one of them looked strange She almost fed it to her dog bu decided to keep it When she was washing ;the carrots she noticed the ring and spoke to her husband, Grams'son, about what she had found.

    They quickly called Grams. “I told her we found her ring in the garden She couldn't believe it, ”Daley said. “It was so strange that the carrot grew perfectly through that ring. ”

    Grams said she wanted to try the ring on again after so many years with her family looking on, she washed the ring with a little soap to get the dirt off. It moved on her finger as easily as i did when her husband gave it to her.

    “We were laughing, ” she said. “It fits. After so many years it still fits perfectly.”

    It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible. Everybody knows that the nicest men would become fierce tigers behind the wheel. It is all right to have a tiger in a cage, but to have one in the driver's seat is another matter altogether.

    Road politeness is not only good manners, but good sense too. It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving．On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and calm so necessary in modern traffic condition. But such behaviors of politeness are by no means enough. Many drivers nowadays don't even seem able to recognize politeness when they see it.

    However, misplaced politeness can also be dangerous. Typical examples are the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may be not able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to. It always amazes me that the highways are not covered with the dead bodies of these grannies (奶奶).

    An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings. Unfortunately, modern drivers can't even learn to drive. Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users. It is high time for all of us to take this message to heart.

    Exciting screams of joy from two happy little girls rang across the beach. But I walked along, ignoring them. I'd come to this faraway beach on my sailboat, a place to escape. My marriage was in trouble. I worried about the harm to my two boys. But I didn't know how to make things better.

    “Help! Help!” The girls screamed. I saw one girl was at the edge of the surf, yelling. I charged into the waves, swam to her and seized her. “But where is the other girl?” I looked across the water and saw a small head after a big wave. I shifted the girl Td rescued to my back. She told me the other girl was her sister. For a moment I thought of my boys. How much they loved each other. How much I loved them.

    I quickened my swimming and held the second little girl. We were at least 50 yards from land. I couldn't swim that far with two girls hanging on to me. But there was no time to wait. I swam as hard as I could, but the weight of the girls grew heavier with every minute. My lungs burned. I opened my mouth to take a breath, but instead swallowed water. I couldn't breathe. From behind me I felt an unbelievable force, lifting.

    “Mommy!” The cry drew my attention. I looked up. An elderly man was trying to drag me out of the water. Two women were swimming toward shore. “Thank you,” one of the woman cried. “You saved my daughters.” My efforts and my struggles had paid off. I thought of that big wave, lifting me and pushing me. When my body had failed me, and when all hope was disappearing, I was given the strength I needed.

    I stoop up. My family were waiting for me. There were things I could do. I just needed to make an effort. The strength would be given to me.
