    Samanta Schweblin, one of the best young Spanish language novelists nominated (提名) by British literary magazine Granta, has visited Beijing to promote the first Chinese edition of a collection of her short stories. The collection, Birds in the Mouth, has been translated and published by Shanghai-based publisher Reader.

    “Sometimes I hold the Chinese edition and choose a story at random and try to guess which one it is. But it is almost impossible for me; even the length is different.” says Schweblin. “When a book is translated into a Western language, I can at least understand some parts of my stories, and therefore suffer some doubt about the quality of the translation. But my Chinese edition is more like an act of faith.”

    Born in Argentina in 1978, Schweblin says she is influenced by the literary traditions of the La Plata area, home to many famous Latin-American novelists.

    Interested in writing stories of ordinary lives where suddenly something extraordinary happens, something new, strange or unknown, she thinks, “The stranger and the unknown are not always related to ghosts or aliens, but can be something related to the known world, something that actually could happen.”

    Birds in the Mouth tells of a divorced father who worries about his 13-year-old daughter and her mysterious appetites. It turns out that his daughter eats live birds.

    The idea for this story came to Schweblin when she was browsing the Internet, “Click, click, click, a picture of a little girl who looks frightened with her hands covering her mouth came to my eyes. Little by little, I developed the story in my mind, and then wrote it down” recalls Schweblin.

    Although there are elements of violence and bloodiness in Schweblin's stories, she skillfully hides them, thinking the trick to writing a thrilling story is to stop the monster from appearing, while maintaining a frightening and mysterious atmosphere.

    We humans spend about one-third of our lives asleep. This may sound like a lot of time, but it is not wasted. Sleep not only helps us stay healthy but it also helps our brains remember. Our brains need good sleep to remember what we do and learn during the other two thirds of our lives when we are awake.

    Researchers at the University of Wisconsin-Madison have found that sleep helps improve brain performance by shrinking(收缩)synapses in the brain. A synapse is the area where cells pass messages to other cells.

    Scientist Chiara Cirelli is a leader at the school's Center for Sleep and Consciousness. She told the reporter that sleep is when the human brain mixes information it has learned while awake into its general collection of knowledge. Meanwhile, the brain forgets unimportant details. This forgetting is important. It makes space for new learning and new memories.

    Cirelli said that the Centers research began with this hypothesis(假设): We sleep so that our brain can repair and refresh itself. She said the idea seems simple and reasonable. However, testing and discovering how it works has been extremely difficult.

    Synapses are only about 20-40 nanometers(纳米)wide. The team began their study by measuring the size of the synapses to look for changes in these already tiny spaces between nerve cells. Cirelli says the process(过程) is difficult because"all the actual measurements of the synapses have to be done by hand." The team had to wait until improvements in laboratory technology made it possible to see these tiny changes. A University of Wisconsin press release called the research a"huge job." Many research specialists worked for four years to photograph, rebuild and study certain areas of a mouse brain. The report also said the scientists measured 6,920 synapses.

    Cirelli says they found that our synapses shrink as our brains clean themselves during sleep. We wake up refreshed and ready to fill those synapses with new information. The research findings are the result of years of hard work at the University of Wisconsin Madison. The researchers published their findings in the journal Science.

    Children who spend more time reading with their parents have a greater chance of becoming better readers than those who don't. With the help from their parents, children can learn techniques to improve their reading skills.

    "A lot of parents think after their child learns to read, they should stop reading to them," Donna George said. "They are sadly mistaken."

    George offers her services to parents at the Title I Learning Centers. She said reading aloud to children may be the most valuable thing parents can do. "It is better for children to hear things at a higher level than where they are," George said. "Parents are their child's first teacher." Parents help their children build listening, phonics, comprehension and vocabulary skills when they read aloud to them.

    Before parents can identify reading problems, they should escape the enemy —television and limit the time their children spend watching television. George suggested not allowing kids to have a TV in their bedrooms, setting a schedule of when kids can watch or keeping a list of how many programs children watch. Louise Joines said while her 14-year-old daughter and 10-year-old son enjoy reading, the television sometimes becomes a distraction. So she tries to build the situation by suggesting books the entire family will enjoy reading together, like the Harry Potter series.

    Parents who do not read themselves should not count on their children being interested in it. If parents would read to their children at least 15 minutes every day, children would not have so many problems in school. It is the parents' job to help build that desire in their children, and of course to know what kind of books to read is also important.

    A new Magic Bench designed by Disney Research lets you interact (互动) with lovely animated (动画的) character—and no special glasses or earphones are required. Instead, the complete environment-the seat, the sitter and the cartoon characters-is mirrored on a screen opposite the bench making it possible for others to watch the scene unfold.

    How does the illusion work? A camera and sensor catch images and gather depth information about physical objects the bench and the person. And then computer translates them into the 3D animations. Meanwhile sensors of touch built into the bench deliver shaking that is happening at the same time and speed to animated actions on the screen, creating the illusion that the animated figures are occupying real-world space next to the user.

    "Our goal for this project was: hear a character coming, see them enter the space, and feel them sit next to you," said Moshe Mahler, principal digital artist at Disney Research. Unlike the traditional mobile technology, one of whose limitations is that only a single user can see its illusion, the Magic Bench allows groups of people to gather in a single environment and collectively participate in an augmented—reality (扩充实境) experience, all at the same time.

    In a video show, a small cartoon donkey runs into view and kicks the bench, causing sharp sound and making the seated person jump in surprise. Another test shows two people on the bench, reacting as they feel an animated rabbit skip up beside them and jump up and down. When a user passes his hand over the rabbit, a shadow moves across its head, as though it were occupying the same physical space as the person next to it.

How to Take Effective Notes During Lectures

Effective note-taking is an active part of the learning process that requires you to get the main idea and write down its key words in your own way.{#blank#}1{#/blank#}

Prepare for the lecture in advance.

Teachers hand out outlines of their lectures before they begin.{#blank#}2{#/blank#}It can help you focus on the difficulties you have in understanding and you will be able to ask better questions in class.

Find your style of taking notes

{#blank#}3{#/blank#}For example, some visual learners could draw certain shapes to represent important concepts. Some people prefer writing words, and some may find it most helpful to record a lecture and listen to it while studying. You have to find the style works best for you.

{#blank#}4{#/blank#}

Rather than writing complete sentences or even complete words, create a form of fast and brief writing with some signs or phrases to make note-taking easier. This will help you take notes quickly and keep up with the lecture.

Take down key points.

It is important to write down key points from the lecture.{#blank#}5{#/blank#}Things like key ideas, definitions, and descriptive phrases can help you remember the subject. For example, if the lecture is based on a specific battle in history, try to write down the date, the major characters involved and the overall outcome of the struggle.

A. Develop your shorthand.

B. Write questions as you are listening.

C. Skimming them will warm up your brain.

D. Everything you learn may be helpful in the future.

E. Different people may have different ways of note-taking.

F. It means you need to focus on the most meaningful information.
