Winters are long and unforgiving in North Dakota. The winter of 1996 was especially brutal. It was a hard time in my own life too, A neck injury had kept me flat in bed for nearly a year. “Just in time for Easter,” my husband, Dick, said. But how could I feel the joy when the snow was four feet deep and I had months of painful physical treatment ahead?

    I was doing the dishes one day, feeling hopeless when there was a tap against the glass. It was a branch of the troublesome cottonwood (棉白杨).Back in the fall of 1979, it was a new subdivision (分支) then, an eight-foot stick. The people who'd briefly occupied the house before us had placed the pipe from the pump next to it. The earth was so wet that the poor thing had fallen down, most of its bare root system pointing skyward, and blowing hopelessly back and forth in the cold wind. Dick decided to pull it out one day, but I disapproved of it.

    “Look at how hard it's trying!” I said, pointing to the way it strongly kept hold of the earth. “It deserves a chance.”

    Dick borrowed some tools. We packed dry soil around the tree and put up some stakes (桩) into the ground, making it stand upright. That winter was still terrible. Surprisingly, in the spring my “rescue stick” put forth a few leaves, then with lots of branches. The year after that, we were able to remove the stakes. By the 1990s that little stick was a giant, towering over the house.

    Now the tapping at the window continued, louder as the wind picked up, almost as though to tell me to look up. At last, I did. I caught ray breath. In the window against the icy blue sky, thousands and thousands of fresh red buds were waving in the wind.

    The tree was bursting with life and I had a wonderful Easter.

    Reading can be a social activity. Think of the people who belong to book group. They choose books to read and then meet to discuss them. Now the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Peterson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    An idea that started in Seattle's public library has spread throughout America. The concept is simple: help to build a sense of community (社区) in a city by getting everyone to read the same book at the same time.

    In addition to encouraging reading as a pursuit (追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as encouraging reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched the “If All of Seattle Read the Same Book” project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.

    In Chicago, the mayor (市长) appeared on television to announce the choice of To Kill a Mockingbird as the first book in the “One Book, One Chicago” program. As a result, reading clubs and neighborhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.

    The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity (一致) can be achieved. Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.

    Ultimately, as Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process, or have enjoyed speaking to someone with whom they would not otherwise have shared a word.

    An Indian movie about two sisters has become a huge hit in China. The Hindi language film, called Dangal, has earned almost $170 million in China since its release there on May 5.

    Much has been written about why Dangal has enjoyed such big success in China. Some people say one reason is that the film's star and producer, Aamir Khan. He is famous in India's Bollywood film industry. Two of his earlier films were also big hits in China.

    Khan's popularity was clear after he got more than 600,000 followers on the Chinese social media service Sina Weibo within two months of joining. But he is not the only reason that the film strongly connects with audience across China. Media has pointed out how it shows similarities between parental systems in China and India.

Dangal is based on the true story of a man who enjoyed the sport of wrestling(摔跤). He competed as a wrestler, but never could achieve his lifelong dream: winning a gold medal. As a father, he wanted his son to win the medal. But his wife only gives birth to daughters. So he finally decides to train them to be world-class wrestlers.

    The movie is more serious than most Bollywood productions, which tell happy love stories and include colorful music and dance performances.

    Edward Chan is a professor at the Hong Kong Polytechnic University. He says the strict way of parenting in the film is something people in China can easily relate to. "I think the father role described by the movie in India is quite to the culture, especially the traditional culture in China."

    The Chinese government supported Global Times newspaper pointed that movie critics (评论家) in China did not like Dangal. Most of them agree with the fact that the father in the film was forceful in pushing his daughters to become wrestlers. But the film Dangal is really aimed to educate children to work for their dreams.

    Beyoncé Knowles can do something that many humans struggle with: sing and dance at the same time. But, it turns out this great ability is not unique to humans. The superb lyrebird, already known to be a gifted singer, can perform coordinated(协调的)song­and­dance routines(一套舞蹈动作)that put most humans to shame.

    The superb lyrebird is one of only two lyrebird species living in Australia, the other named Albert's lyrebird. Male lyrebirds have tails in the shape of an ancient musical instrument when spread out. Like most animals with beautiful body parts, the males use their tails to attract females. Each one sets up a small mound(小丘)on the forest floor, where he walks around proudly and sings. He also shows his tail by holding it over his head.

    Lyrebirds are gifted mimics(模仿者), so their songs combine their own calls, the songs of other species, and sounds they have heard in the forest. That would be enough showing off for other animals, but male superb lyrebirds also dance.

    Anastasia Dalziell of the Australian National University in Canberra filmed 12 lyrebirds in the wild. She found that males only danced during four song types, and that each song type was accompanied by a specific move. “Lyrebirds match different dance styles to different types of songs, ”she says. For example, when the male sang a series of rapid notes he also stepped to the side and held his tail wide. Another song type was accompanied by jumping and moving up and down, with the tail held narrow.

    “Our results suggest that the coordination between song and dance—like movements we see in humans can occur in other animals,” says Dalziell. Female lyrebirds might prefer males that are better at coordinating song and dance, although there is no evidence of that yet.
