For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive （善于接受的） to such messages.

    Scientists are using powerful radio telescope to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan (扫视) the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.

    Of the 200 billion stars in the Milky Way galaxy （银河星系）, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.

    However, many scientists wonder whether intelligent （有智力的） life exists on other planets. Some believe that twenty years of searching without any intelligible （可理解的） messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.

    Other scientists believe that our search hasn't been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family in only about five billion years old,  our galaxy is about 20 billions years old. In that time, some scientists think it is likely that civilizations are much more advanced than ours. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.

    Every year gray whales swim a 10,000 miles round-trip, from the cold waters near Alaska, down the coast of North America to the warm waters near Mexico, and back again. It is one of the longest migrations (迁徙) of any mammal (哺乳动物).

    All day, all summer long, in the cold waters near Alaska, gray whales eat and eat.

    Instead of teeth, gray whales have baleen (鲸须) they use to get food from ocean water. They get big mouthfuls of muck (淤泥) from the ocean floor, then push that muck right back out through their baleen. The mucky water flows through, but tiny animals get trapped in the baleen and licked up.

    When the water starts to freeze, the whales begin their long trip south. They swim night and day, without stopping to eat or rest. During the long journey, migrating whales may push their heads out of the water to see where they are.

    Two months later, the whales reach Mexico. Babies are born here in warm, shallow (浅的) waters called lagoons (濒海湖). Ocean lagoons have no food for the adults, but the babies are safer here than in the open seas. All winter the babies grow big and strong.

    In spring first the dads and teenagers leave the lagoons, then the moms with babies. Migrating gray whales swim close to shore, especially moms with babies. The ice is melting up (融化) north, and it's time for the hungry whales to make the long journey back to their summer feeding grounds.

    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.

    Not so long ago, most people didn't know who Shelly Ann Francis Pryce was going to become. She was just an average high school athlete. There was every indication that she was just another Jamaican teenager without much of a future. However, one person wants to change this. Stephen Francis observed then eighteen-year-old Shelly Ann as a track meet and was convinced that he had seen the beginning of true greatness. Her time were not exactly impressive, but even so, he seemed there was something trying to get out, something the other coaches had overlooked when they had assessed her and found her lacking. He decided to offer Shelly Ann a place in his very strict training seasons. Their cooperation quickly produced results, and a few year later at Jamaica's Olympic games in early 2008, Shelly Ann, who at that time only ranked number 70 in the world, beat Jamaica's unchallenged queen of the sprint(短跑).

    “Where did she come from?” asked an astonished sprinting world, before concluding that she must be one of those one-hit wonders that spring up from time to time, only to disappear again without signs. But Shelly Ann was to prove that she was anything but a one-hit wonder. At the Beijing Olympic she swept away any doubts about her ability to perform consistently by becoming the first Jamaican woman ever to win the 100 meters Olympic gold. She did it again one year on at the World Championship in Briton, becoming world champion with a time of 10.73—the fourth record ever.

    Shelly-Ann is a little woman with a big smile. She has a mental toughness that did not come about by chance. Her journey to becoming the fastest woman on earth has been anything but smooth and effortless. She grew up in one of Jamaica's toughest inner-city communities known as Waterhouse, where she lived in a one-room apartment, sleeping four in a bed with her mother and two brothers. Waterhouse, one of the poorest communities in Jamaica, is a really violent and overpopulated place. Several of Shelly-Ann's friends and family were caught up in the killings; one of her cousins was shot dead only a few streets away from where she lived. Sometimes her family didn't have enough to eat. She ran at the school championships barefooted because she couldn't afford shoes. Her mother Maxime, one of a family of fourteen, had been an athlete herself as a young girl but, like so many other girls in Waterhouse, had to stop after she had her first baby. Maxime's early entry into the adult world with its responsibilities gave her the determination to ensure that her kids would not end up in Waterhouse's roundabout of poverty. One of the first things Maxime used to do with Shelly-Ann was taking her to the track, and she was ready to sacrifice everything.

    It didn't take long for Shelly-Ann to realize that sports could be her way out of Waterhouse. On a summer evening in Beijing in 2008, all those long, hard hours of work and commitment finally bore fruit. The barefoot kid who just a few years previously had been living in poverty, surrounded by criminals and violence, had written a new chapter in the history of sports.

    But Shelly-Ann's victory was far greater than that. The night she won Olympic gold in Beijing, the routine murders in Waterhouse and the drug wars in the neighboring streets stopped. The dark cloud above one of the world's toughest criminal neighborhoods simply disappeared for a few days. “I have so much fire burning for my country,” Shelly said. She plans to start a foundation for homeless children and wants to build a community centre in Waterhouse. She hopes to inspire the Jamaicans to lay down their weapons. She intends to fight to make it a woman's as well as a man's world.

    As Muhammad Ali puts it, “Champions aren't made in gyms. Champions are made from something they have deep inside them. A desire, a dream, a vision.” One of the things Shelly-Ann can be proud of is her understanding of this truth.

    When I was six, Dad brought home a dog one day, who was called “Brownie". My brothers and I all loved Brownie and did different things with her. One of us would walk her, another would feed her, then there were baths, playing catch and many other games, Brownie, in return, loved each and every one of us. One thing that most touched my heart was that she would go to whoever was sick and just be with them, we always felt better when she was around.

    One day, as I was getting her food, she chewed up(咬破)one of Dad's shoes, which had to be thrown away in the end. I knew Dad would be mad and I had to let her know what she did was wrong. When I looked at her and said, "Bad girl," she looked down at the ground and then went and hid. I saw a tear in her eyes.

    Brownie turned out to be more than just our family pet, she went everywhere with us. People would stop and ask if they could pet her. Of course she'd let anyone pet her. She was just the most lovable dog. There were many times when we'd be out walking and a small child would come over and pull her hair. she never barked(吠) or tried to get away. Funny thing is she would smile. This frightened people because they thought she was showing her teeth. Far from the truth, she loves everyone.

(Now many years have passed since Brownie died of old age. I still miss days when she was with us.)
