“Don't you have any toys you want to share?” I asked my son during our church's Christmas toy drive. “What about all those things in your closet you haven't used in years?”

    "I don't have anything,” he said. “We're so poor.”

    We're only “poor” because we refuse to buy him the phone he wants for Christmas, which would also require a monthly texting charge.

    “You're not so poor you have nothing to give,” I found myself saying to him, a phrase my mother often used on me.

    At work the next day, one of my students said, “I didn't spell your name right,” as she handed me a Christmas gift—a box of chocolates. No wonder she hadn't spelled it right—I had only worked at the center for a couple of months, and my name is not easy to pronounce, even in English, which is this woman's second language.

    I hadn't expected a gift—I worked at an adult education center, where we dealt with people who struggle economically. When I was hired, my boss told me she tries to keep snacks around the center and cooks “stone soup” once a week, where whoever can bring something in does, because “You will hear growling bellies here. They give their food to the children before they themselves eat.”

    And yet these people, so grateful for a second chance at getting an education, unable to sometimes even afford the gas money to come in, manage to do something for us nearly every week. Some bring in food; others do chores around the center. They help and encourage one another, and us. They give what they are able to give.

    We've all been there: in a lift, in line at the bank or on airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.

    What's the problem? It's possible that we all have compromised conversational intelligence. It's more likely that none of us start a conversation because it's awkward and challenging, or we think it's annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it's an invaluable social practice that results in big benefits.

    Dismissing small talk as unimportant is easy, but we can't forget that deep relationships wouldn't even exist if it weren't for casual conversation. Small talk is the grease (润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. "Almost every great love story and each big business deal begins with small talk," he explains. "The key to successful small talk is learning how to connect with others, not just communicate with them."

    In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. "It's not that talking to the waiter is better than talking to your husband," says Dunn. "But interactions with peripheral(边缘的) members of our social network matter for our well-being also."

    Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. "Small talk is the basis of good manners," he says.

    It's a little hard to figure out the rules for sure,  but the baby African buffalo( 水牛) seems to have the upper hand. The two stand a couple feet apart, staring at each other. Behind them, their mothers look on with the kind of indifference(不关心) of mothers  everywhere who see their kids playing a harmless game.

    The alarm went off about half an hour ago, the second time tonight. Here, one bell means “elephant”, two, “rhino” (犀牛), and three and four, 1 really can't remember for what, because when you're awoken by bells in the middle of the night, your first thought won't be “Animal! ”.But as soon as I realized it was the rhino alarm.

    I was running for the stairs. Yet I'm the only one watching the animals stare-down. Either everyone else died of a heart attack when the bells went off, or l was the only one in the entire hotel who didn't turn the alarm switch to off before going to bed.

    The Ark, a hotel shaped like the biblical ark(圣经的方舟) , lies in the highlands of Kenya's Aberdare National Park, about 100 kilometers north of Nairobi. At the Ark's prow(船首) are huge windows overlooking a waterhole. Earlier tonight, I'd watched a pack of wolves, buffalos and elephants. And now, at three or so in the morning, I'm down for rhino bells. The first time, 2.5 hours ago, it was a single black rhino, which came down, got a drink, and left. I'd have been sorry for the lost sleep.  I've already arranged with a guide to take me out at sunrise for the so-called “should never miss” bird-watching, where we'll get to see 30 species, but really, how many times in your life will you get to wake up and say, “Wow! Rhino!”? Isn't that the definition of a pretty good night? Last week we went from Uganda into Kenya.  Before I left home, 1 thought I'd be happy with ten elephants and five or six giraffes on the whole trip. I didn't dare to dream the rhino.

    I study English literature at university and have always been proud of Britain's literary heritage(文学遗产). Some British authors that you may have heard of are Charles Dickens and Jane Austen. These writers are famous all over the world because their books have been translated into many different languages. In the UK, their novels are celebrated as some of the best that have ever been written. We say that these novels are "classic" because they are still read and enjoyed years after their publication.

    I read classic novels because they are part of my university lessons but also because I enjoy them. They can teach you a lot about how people used to live and what society was like in the past. Novels like Hard Times by Charles Dickens remind us of the poverty in London during the Industrial Revolution while Jane Austen's fiction shows us what family life was like in the 18th century.

    Classic novels usually have memorable stories land interesting characters. One of my favourite books is Charles Dickens Great Expectations. It is about a boy called Pip who suddenly receives a lot of money from a mysterious supporter. As he grows up, his character changes: he becomes quite selfish and mean. Another important character is Miss Havisham. When she was young, her fiancé ran away on their wedding day. She lives in a dark house and still wears her wedding dress. She is a fascinating character, both sad and scary.

    Reading classic novels enriches my knowledge and life experience. And it has become part of life.

Biologists from the John Innes Centre in England discovered that plants have a biological process which divides their amount of stored energy by the length of the night. This solves the problem of how to portion out (分配) energy reserves during the night so that the plant can keep growing, yet not risk burning off all its stored energy.

While the sun shines, plants perform photosynthesis (光合作用). In this process, the plants change sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch (淀粉). At night, the plants burn this stored starch to fuel continued growth.

"The calculations are precise so that plants prevent starvation but also make the most efficient use of their food," said study co-author Alison Smith. "If the starch store is used too fast, plants will starve and stop growing during the night. If the store is used too slowly, some of it will be wasted. "

The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. To give the plants some math tests, the biologists let night arrive unexpectedly early or late for them.

During one of the exams, they shut off the lights early on them that had been grown with twelve-hour days and nights. Putting them into darkness after only an eight-hour day means they didn't have time to store as much starch as usual. And this forced the plants to adjust their normal nightly rhythm.

Amazingly, even after this day length trick, the plants did very well in their exams and ended up with just five percent of starch left over at the end of the night. They had neither starved, nor stored starch that could have been used to fuel more growth.

The authors suggested that similar biological calculators may explain how a migratory bird, the little stint, can make a five-thousand-kilometer journey to their summer habitat in the Arctic and arrive with enough fat reserves to survive only approximately half a day more, on average.

The results of the study were published in e Life.
