Finding time to red is an important part of developing literacy skills for all kids. And there are many easy and convenient ways to make reading a part of each day-even when it's tough to find time to sit down with a book.

Reading opportunities are everywhere you go. While riding in the car, for example, encourage kids to spot words and letters (on billboards, store signs, etc.), turning it into a game (“Who'll be the first to find a letter B?”). While shopping, ask your preschooler to “read” pictures on boxes and tell you about them. Point out the difference between the words and the pictures on the boxes. Encourage older kids to tell you what's on the shopping list.

    Even daily tasks like cooking can provide reading moments. You can read recipes aloud to younger kids, and older kids can assist you as your cook by telling you how much flour to measure. Give your child a catalog to read while you sort through the mail. Ask relatives to send your child letters, e-mails, or text messages, and read them together. Help your child create letters or messages to send back to the relatives. These types of activities help kids see the purpose of reading and of print.

Even when you're trying to get things done, you can encourage reading. While cleaning, for instance, you might ask your child to read a favorite book to you while you work. Younger kids can talk to you about the pictures in the favorite books.

    Make sure kids get some time to spend quietly with books, even if it means cutting back on other activities, like watching TV or playing video games.

    Most importantly, be a reader yourself. Kids who see their parents reading are likely to resemble them and become readers, too!

    Raised in a fatherless home, my father was extremely tightfisted towards us children. His attitude didn't soften as I grew into adulthood and went to college. I had to ride the bus whenever I came home. Though the bus stopped about two miles from home, Dad never met me, even in severe weather. If I grumbled, he'd say in his loudest father-voice, “That's what your legs are for!” The walk didn't bother me as much as the fear of walking alone along the highway and country roads. I also felt less than valued that my father didn't seem concerned about my safety. But that feeling was canceled one spring evening.

    It had been a particularly difficult week at college after long hours in labs. I longed for home. When the bus reached the stop, I stepped off and dragged my suitcase to begin the long journey home.

    A row of hedge（树篱）edged the driveway that climbed the hill to our house. Once I had turned off the highway to start the last lap of my journey, I always had a sense of relief to see the hedge because it meant that I was almost home. On that particular evening, the hedge had just come into view when I saw something gray moving along the top of the hedge, moving toward the house. Upon closer observation, I realized it was the top of my father's head. Then I knew, each time I'd come home, he had stood behind the hedge, watching, until he knew I had arrived safely. I swallowed hard against the tears. He did care, after all.

    On later visits, that spot of gray became my watchtower. I could hardly wait until I was close enough to watch for its secret movement above the greenery. Upon reaching home, I would find my father sitting innocently in his chair. “So! My son, it's you!” he'd say, his face lengthening into pretended surprise.

      I replied, “Yes, Dad, it's me. I'm home.”

    As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.

    Three Chilean students got the idea for a plant-powered device(装置) to charge（使……充电） their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.

    “It occurred to Camila to say about plants,” said inventor Evelyn Aravena. “'Why don't you have a socket, if there are so many plants? 'After that, we thought, 'why don't they have a charging outlet（插座）? Because there are so many plants and living things that have the potential to produce energy, why not?'”

    Their invention—a small biological circuit called E-Kaia—uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.

    "It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them." said Mauricio Cifuentes.

    The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.

    "Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

    But plants are everywhere, and the bio－circuit makes good use of their excess(过多的) power.

    The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.

    The student inventors have applied for patents（专利） on their technology, and expect the E-Kaia to go on sale in the near future.

    Scientists recently discovered three tyrannosaur (霸王龙) trackways in Canada. The trackways suggest the meat eaters traveled and hunted in groups. The 70-million-year- old footprints are the first tyrannosaur trackways ever found.

    Tyrannosaurs were a type of meat-eating dinosaur that included the strong Tyrannosaurus rex and Albertosaurus. “Groups of tyrannosaurs may have stuck together as a group to increase their chances of bringing down animals and individually surviving,” study coauthor Richard McCrea says. He works for Canada's Peace Region Paleontology Research Centre. It's believed that tyrannosaurs were solitary creatures. The newly discovered trackways could change the way scientists look at these frightening beasts.

    Trackways can uncover a lot about the social behavior of a species. Unfortunately, very few tyrannosaur footprints have ever been found, and until recently, the only ones known were single prints discovered in Mongolia, the western U.S., and western Canada. But in October 2011, a hunting guide named Aaron Fredlund found two tyrannosaur track marks near Tumbler Ridge, an area in the foothills of the Canadian Rockies. Over the next year, McCrea and his team searched the site and found the remaining trackways.

    The footprints are at about the same depth, which suggests the tyrannosaurs moved through the area at the same time. Impressions of the dinosaurs' rough skin are even visible in the prints. The prints are also in near-perfect condition. That's because the ground had a high clay (黏土 ) content when the dinosaurs walked through the area. The land was later covered by a thick layer of volcanic ash, which kept the marks intact (完整). "This is the most ideal situation you could ask for," McCrea says.

    Researchers aren't sure of the exact species of tyrannosaur that left the prints. But the historic findings show a great deal about how the beasts moved and behaved. “We have extremely convincing evidence that tyrannosaurs traveled in groups,” says McCrea. "This is probably the most important evidence to come out to date on that topic."

    In the classic marriage vow (誓约), couples promise to stay together in sickness and in health. But a new study finds that the risk of divorce among older couples rises when the wife－not the husband－becomes seriously ill.

    "Married women diagnosed with a serious health condition may find themselves struggling with the impact of their disease while also experiencing the stress of divorce." said researched Amelia Karraker.

    Karraker and co-author Kenzie Latham analyzed 20 years of data on 2,717 marriages from a study conducted by Indiana University since 1992. At the time of the first interview, at least one of the partners was over the age of 50.

    The researchers examined how the onset (发生) of four serious physical illnesses affected marriages. They found that, overall, 31% of marriages ended in divorce over the period studied. The incidence of new chronic (慢性的) illness onset increased over time as well, with more husbands than wives developing serious health problems.

    "We found that women are doubly weak when their marriage breaks up in the face of illness," Karraker said. "They're more likely to be widowed, and if they're the ones who become ill, they're more likely to get divorced."

    While the study didn't assess why divorce is more likely when wives but not husbands become seriously ill, Karraker offers a few possible reasons. "Gender roles and social expectations about caregiving may make it more difficult for men to provide care to sick spouses." Karraker said. "And because of the imbalance in marriage markets, especially in older ages, divorced men have more choices among potential partners than divorced women."

    Given the increasing concern about health care costs for the aging population, Karraker believes policymakers should be aware of the relationship between disease and risk of divorce.

    "Offering support services to spouses caring for their other halves may reduce martial stress and prevent divorce at older ages." she said. "But it's also important to recognize that the pressure to divorce may be health-related and that sick ex-wives may need additional care and services to prevent worsening health and increased health costs."

    Are you interested in country music? I like it very much! It will take me away for a while after I am tired. The guitars and songs will take me to mountains and fields. Country music usually talks of everyday life and feelings. It's the spirit of America, easy to understand, slow and simple. Country music developed in the Southern United States. It was the folk music of American countryside. Many of songs tell about the lives of farmers. They talk about love, crops or death.

    The life of the countryside can be hard, so the words in country music are often sad. At first, people played the music only at family parties. But it became more popular later. In the 1920s, people played country songs on the radio, and they made them into records. When people in the countryside moved to towns and cities to look for work, they took their music with them. Country music continued to change and became popular across America. John Denver was one of America's most famous country singers in the 1970s. His song "Take Me home, Country Roads" is well-known and people still play it today.
