Little Tom down the street calls our dog "The keep dog". Zip is a sheep dog. But when Tom tries to say " Sheep", it comes out "keep". And in a way Tom is right. Zip is always bringing things home for us to keep! I'll tell you about some of them. Zip's first present was a shoe. It was made of green silk. We didn't know how Zip found the shoe. But after a moment, Mary, my big sister, told me the shoe had a strange smell. I nodded(点头) and held my nose. "What do you think it is?" "It smells like something for cleaning. I think someone tried to clean a spot (污点) off the shoe. Then he put it at the door to dry." Along came Zip. And good-bye shoe!" I said. "We should take it back." "We can't".said my sister. "Maybe little Tom is right," Mary said. "Maybe Zip is a keep dog!"

    He was the baby with no name. Found and taken from the north Atlantic 6 days after the sinking of the Titanic in 1912, his tiny body so moved the salvage (救援) workers that they called him “our baby.” In their home port of Halifax, Nova Scotia, people collected money for a headstone in front of the baby's grave (墓), carved with the words: “To the memory of an unknown child.” He has rested there ever since.

    But history has a way of uncovering its secrets. On Nov. 5, this year, three members of a family from Finland arrived at Halifax and laid fresh flowers at the grave. “This is our baby,” says Magda Schleifer, 68, a banker. She grew up hearing stories about a great-aunt named Maria Panula,42, who had sailed on the Titanic for America to be reunited with her husband. According to the information Mrs. Schleifer had gathered, Panula gave up her seat on a lifeboat to search for her five children -- including a 13-month-old boy named Eino from whom she had become separated during the final minutes of the crossing. "We thought they were all lost in the sea," says Schleifer.

    Now, using teeth and bone pieces taken from the baby's grave, scientists have compared the DNA from the Unknown Child with those collected from members of five families who lost relatives on the Titanic and never recovered the bodies. The result of the test points only to one possible person: young Eino. Now, the family sees no need for a new grave. "He belongs to the people of Halifax," says Schleifer, "They've taken care of him for 90 years."

    Having a smart phone may not be as smart as you think. They may let you surf the Internet, listen to music and take photos wherever you are…but they also turn you into a workaholic（工作狂）,it seems.

    A study suggests that, by giving you access to emails at all times, the smart phone adds as much as two hours to your working day. Experts found that British people work an additional 460 hours a year on average as they are able to respond to emails on their mobiles. The study shows the average UK working day is between 9 and 10 hours, but 2 more hours is spent responding to or sending work emails, or making work calls.

    Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers say they are on call almost 24 hours a day. Nearly two-thirds say they often check work emails just before they go to bed and as soon as they wake up, while over a third have replied to one in the middle of the night. The average time for first checking emails is between 6 a.m and 7 a.m, with more than a third checking their first email in the period, and a quarter checking them between 11 p.m.and midnight.

    Ghadi Hobeika, marketing director of Pixmania, said: “The ability to access millions of Apps has made smart phone invaluable for many people. However, there are disadvantages. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smart phones mean that people cannot get away from work. The more frequently in contact we become, the more is expected of us in a work capacity.”

    Dave Merry and his tools have been through a lot together. The tools helped Dave, now 80, repair his home in St. Paul, Minnesota, where he and his wife, Annette Merry, lived for 46 years and raised three children. The table saw, the jointer plane, the drill press, and the dozens of other power and hand tools had pride of place in his carefully organized workshop. "I had a whole setup, and it was beautiful," says Dave, a retired engineer.

    But then Annette experienced a stroke (中风) that left her relying on a walker to get around, and the Merrys decided to move into assisted living. Dave's workshop was obviously a minor consideration given Annette's condition, but the family knew that giving it up, on top of everything else, would hurt.

    It was the Merrys' daughter who came up with a possible solution. She'd heard about some people who were setting up a tool library—a nonprofit facility that would lend out tools just as a regular library lends books. Might Dad be interested in donating his?

    "I said yes," Dave says.

    The people creating the St. Paul Tool Library were thrilled. They had expected it would take a year to collect enough tools to make their facility fully functional. Instead it took one day: the day Dave donated his.

    The library's founders drove over to the Merrys' house and picked everything up themselves. The library is housed in the basement of the American Can Factory. Members pay an annual fee (from $20 to $120) for unlimited tool use and a varying number of visits to the workshop. And they get an extra benefit: Dave Merry. "Almost every time we're open, Dave's here," says one of the founders, Peter Hoh. "It means a lot to me to be able to go and use my tools," Dave says. "But it means just as much to help DIYers use the tools properly."

    As Hoh puts it, "This is his workshop now."
