A 17-year-old boy, caught sending text messages in class, was recently sent to the vice principal's office at Millwood High School in Halifax, Nova Scotia. The vice principal, Steve Gallagher, told the boy he needed to focus on the teacher, not his cellphone. The boy listened politely and nodded, and that's when Mr. Gallagher noticed the student's fingers moving on his lap. He was texting while being scolded for texting. “It was a subconscious act,” says Mr. Gallagher, who took the phone away. “Young people today are connected socially from the moment they open their eyes in the morning until they close their eyes at night. It's compulsive.”

    A study this year by psychology students at Covenant College in Lookout Mountain, Ga., found that the more time young people spend on Facebook, the more likely they are to have lower grades and weaker study habits. Heavy Facebook users show signs of being more sociable, but they are also more likely to be anxious, hostile or depressed. (Doctors, meanwhile, are now blaming addictions to 'night texting' for disturbing the sleep patterns of teens.)

    Almost a quarter of today's teens check Facebook more than 10 times a day, according to a 2009 survey by Common Sense Media, a nonprofit group that monitors media's impact on families. Will these young people get rid of this habit once they enter the work force, or will employers come to see texting and 'social-network checking' as accepted parts of the workday?

    Think back. When today's older workers were in their 20s, they might have taken a break on the job to call friends and make after-work plans. In those earlier eras, companies discouraged non-business-related calls, and someone who made personal calls all day risked being fired. It was impossible to imagine the constant back-and-forth texting that defines interactions among young people today.

    Educators are also being asked by parents, students and educational strategists to reconsider their rules. “In past generations, students got in trouble for passing notes in class. Now students are skilled at texting with their phones still in their pockets,” says 40-year-old Mr. Gallagher, the vice principal, “and they're able to communicate with someone one floor down and three rows over. Students are just fundamentally different today. They will take suspensions rather than give up their phones.”

    There are many fun, free activities that you can do as a family. All that is required is a bit of imagination and some time set aside for fun. And the best part is that these are the kind of memories a child will remember for a lifetime.

Family game night

    Find out any of the games that are already around the house. Kids often get computer games for Christmas or birthdays, and would love to have a chance to play with their family. Or, make up some games of your own. “Charades” is a fun game to play that will challenge a child to use his/her imagination. Divide the family into teams and let each team come up with words that the other has to act out.

Family art time

    Pick some time for the family to sit down and come up with their own masterpiece. It doesn't need to be just a drawing -- take some old magazines sitting around the house, let the kids cut out pictures and paste them into their own montage. Or, use items from nature. Let them use leaves, pine cones, twigs and whatever else they can find to create something from their imaginations.

Family Picnic

    Taking the family for a picnic is a great way for some fun that doesn't cost any money. If the weather is nice, take them to a park or playground and let the kids have a day of playing. Or, if it is the middle of winter and a foot of snow is on the ground, set up a picnic in the living room.

Family Field Trip

    A family field trip doesn't have to cost a dime. Ask a nearby farm if it would be alright to bring your kids out for a tour and to see some of the animals. Or take them to a park and make a scavenger hunt where they need to find certain items from nature. Ask a local business if you could bring the family for a tour to see how things work -- you might be surprised at the number of people who would be thrilled to share what they do with others, and it could be an interesting lesson for the kids.

    My timing has always been a little off with Elizabeth Strout. I've read and pretty much admired everything she's written, but, for whatever reason, the books of hers I've picked to review have been the good ones, like Amy and Isabelle andThe Burgess Boys, rather than the extraordinary ones, like Olive Kitteridge, which won the 2009 Pulitzer Prize. Anything Is Possible is Strout's latest book and it's gorgeous. Like Olive Kitteridge, Anything Is Possible reads like a novel constructed out of linked stories. In fact, it's hard to know exactly what to call this — a novel or a short story collection. In any case, these stories are animated (栩栩如生) by Strout's signature themes: class humiliation, loneliness, spiritual and, sometimes, reawakening. When Strout is really on her game, as she is here, you feel like you've been carefully lowered into the unquiet depths of quiet lives.

    Strout began working on Anything Is Possible at the same time she was writing her novel My Name Is Lucy Barton, which was published last year. Lucy, a dirt-poor child who grows up to become a celebrated writer, floats in and out of these interlocking stories. Some characters catch a glimpse of her being interviewed on TV; one travels to see her at a bookstore. An older Lucy even appears “in the flesh” in one story when she returns home to the small town in rural Illinois where most of these tales are set to visit her troubled brother; but Anything Is Possible also stands on its own. Indeed, a few of the characters here would be ticked off if they thought their stories depended in any way on that Barton girl. Strout's writerly eye works like a 360 degree camera, so that a character or place that's on the margins of one tale takes center stage in a later one. This technique sounds contrived, but Strout carries it off lightly.

    ①One of the most powerful stories here is called “Dottie's Bed & Breakfast,” which is an establishment we readers glimpse earlier in the book. Dottie desires to be middle-class and she harbors a grudge (怨恨) against life because she's had to rent out rooms to make a living. Dottie also possesses a sensitive nose for sniffing out the lower-class origins of some of her guests.

    ②“Shoes always gave you away,” comments a woman in a story called “Cracked” about a houseguest's too-high cork wedges(坡跟鞋). And, in the final story here, called “Gift,” a once-poor man made good says, “The sense of apology did not go away, it was a tiring thing to carry.”

    ③But, back to Dottie. When an elderly doctor and his wife come to stay at her guesthouse, Dottie bonds over tea with the wife, Shelley, who shares a story about a long-ago social humiliation.

    ④At breakfast the next morning, however, Shelley obviously regrets that confidence and becomes the Doctor's wife again. She freezes Dottie out and puts her back in her place as the inn-keep.

    There's comic satisfaction in seeing Dottie secretly spitting into the breakfast jam, but the more profound rewards of this story have to do with its recognition of the many varieties of human insecurity — or, as Lucy Barton herself more bluntly puts it, the many ways “people are always looking to feel superior to someone else.”

    Other stories have to do with sexual shame, or with the tragic ways close neighbors or family members misread each other; but I'm making Anything Is Possible sound too grim when, in fact, so many of these stories end in an understated (低调的) gesture of forgiveness. Strout is in that special company of writers like Richard Ford, Stewart O'Nan and Richard Russo, who write simply about ordinary lives and, in so doing, make us readers see the beauty of both their worn and rough surfaces and what lies beneath.

    Emily Temple-Wood was 12 years old the first time she was bullied(欺凌) online. They left ugly comments on her Wikipedia and Facebook pages about her looks "that would make my mother's hair curl." says Temple-Wood, now 22 and in medical school. The reason? "I was a woman on the Internet," she said.

    Over the years, she considered how she might take revenge(复仇). Then, as a freshman in college, it hit her: "What do misogynists(men who hate women) hate most?" she asked herself. "Women who are productive!" Her solution: For every rude comment she received, Temple-Wood would post a biography(传记) of a woman scientist, and thus, in 2012, Wiki Project Women Scientists was born. She wrote about her heroes, like Barbara McClintock, who received the 1983 Nobel Prize in Physiology or Medicine, and Caroline Still Anderson, one of the first African American women to become a doctor in the United States, in the late 1800s. With help from other women, many of them scientists who have also been bullied online, Temple-Wood has published hundreds of these biographies and women of all ages have taken notice.

    "When I was a kid, I could count the number of women scientists I knew about on one hand," wrote Siko Bouterse, who used to work for the Wikimedia Foundation. "But our daughters have the chance to get much more knowledge about scientists who look like them because of Emily.

    The ugly comments still come, says Temple-Wood. Being a strong woman online is not easy. "We all have days when we break down and need to have a glass of wine," she says. "I tell people who are being bullied that it's OK to be sad. But now you need to find a productive way to take revenge."

    A traveller was staying in an Egyptian village. One day, she held up her camera to take pictures of the children. Suddenly the young ones began to shout at her. The traveller's face turned red and she apologized to the head for what she was doing, and told him she had forgotten that people in some places believed a person would lose his soul(灵魂) if his picture was taken. She explained to him the operation of a camera for a long time. Several times the head tried to say something, but he couldn't. When she believed that the head didn't fear any longer, the traveller then let him speak. With a smile, he said, "The children were trying to tell you that you forgot to take off the lens(镜头) cap!"

I was asked by a reader recently why so many animals seem to have pink ears，when their bodies are all different colours? The truth is that most animals actually don't have pink ears. Let us explain.

Near the equator (赤道), where the climate is hot, animals are likely to have darker skin, including on their ears. Think of the African elephant, which has quite dark ears. In colder climates, skin colour is usually lighter and often pink.

Why is skin colour different in different climates? Skin pigmentation, which is what gives skin its colour, can protect against sunburn and skin cancer. When animals live in colder parts of the world, they don't need it as much to survive. Light-coloured skin also helps animals stay warmer because it reduces heat loss, which is useful if you're in a colder climate.

For most animals, the colour of their fur or other body covering has generally developed as camouflage. That allows animals to mix into the background and avoid being eaten, or for predators (捕食者) to remain hidden during hunting. One example is the sandy-coloured coat of the desert fennec fox, which uses camouflage for both hunting and hiding.

By the way, in many animals, ears come in many different shapes and sizes. For example, in bats, the serval (a type of African wildcat) and the fennec fox, the ears are large compared to their body size—this helps them hear better because it allows them to sense more sound waves. Naked mole-rats have tiny ears because they need to dig a lot. Big ears would get in the way. The other downside of big ears is that you can lose a lot of body heat. That's why animals that live in really cold places, like the Arctic fox, have quite small ears.
