Adding math talk to story time at home is a winning factor forchildren's math achievement, according to a new research from the University ofChicago. The study from psychologists Sian Beilock and Susan Levine shows amarked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together.

    Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to beanxious or uncomfortable with math.

    Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement.

    The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement.

  “Many Americans experience high levels of anxiety when they haveto solve a math problem, with a majority of adults feeling at least some worries about math,” said Beilock, professor in Psychology andauthor of Choke, a book about stress and performance. “These math-anxiousparents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way.”

    Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math.

    The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar studentsin the reading group by almost three months in math achievement at year's end.

    The kids in a village in Ethiopia wear dirty, ragged clothes. They sleep beside cows and sheep in huts made of sticks and mud. They have no school. Yet they all can chant the English alphabet, and some can make words.

    The key to their success: 20 tablet computers(平板电脑) dropped off in their Ethiopian village in February by a U.S. group called One Laptop Per Child.

The goal is to find out whether kids using today's new technology can teach themselves to read in places where there are no schools or teachers. The Massachusetts Institute of Technology researchers analyzing the project data say they're already amazed. “What I think has already happened is that the kids have already learned more than they would have in one year of kindergarten,” said Matt Keller, who runs the Ethiopia program.

    The fastest learner—and the first to turn on one of the tablets—is 8-year-old Kelbesa Negusse. The device's camera was disabled to save memory, yet within weeks Kelbesa had figured out its workings and made the camera work. He called himself a lion, a marker of accomplishment in Ethiopia.

With his tablet, Kelbasa rearranged the letters HSROE into one of the many English animal names he knows. Then he spelled words on his own. “Seven months ago he didn't know any English. That's unbelievable,” said Keller.

    The project aims to get kids to a stage called “deep reading,” where they can read to learn. It won't be in Amharic, Ethiopia's first language, but in English, which is widely seen as the ticket to higher paying jobs.

    Taking Care of Your Eyes

    Many of us don't pay much attention to the importance of eye care. It is said that if you take care of your eyes, then you can surely be healthy.{#blank#}1{#/blank#}Natural eye care should be put in a number one place.

    There are several causes leading to poor eyesight like not enough food, genes(基因) and aging(老化).{#blank#}2{#/blank#} If you happen to work in front of the computer, it is best to take a break every once in a while.

    Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water.{#blank#}3{#/blank#} For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight from UV rays.

    {#blank#}4{#/blank#}Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises regularly and eats the right kind of food, his eyes will stay in good condition for a long time.

    {#blank#}5{#/blank#} In a word, eye care is very important, no matter how old a person is.

A. Such behavior will do harm to our eyes.

B. What can we do to protect our eyesight?

C. That's why our eyes should be given lots of care.

D. Eating healthy food will do good to your eyesight.

E. You must also try your best to protect your eyes from harmful things.

F. All above are natural ways of eye care that can help us keep healthy eyes.

G. Televisions, computers and reading are also the causes of having poor eyesight.

    As an expert on the science of sleep and sleep disorders, Michael Twery believes “People have good understanding about the necessity of sleeping 7-8 hours in bed. But they undervalue the function of napping in day.”

    For example, many Americans do nap. But one-third of adults in the US are also frequently tired. Someone who naps as a way of paying off a sleep debt may not experience the same improvements from napping as a healthy, well-rested person would.

    Also, many people may not want to admit that they take a nap. That only children, the very old, sick or lazy people nap is a common opinion. In fact, Americans sometimes do very strange things. For those who claim they only sleep five hours a night, they may think they are somehow stronger than the average human—superhuman, if you will.

    Luckily, many offices now offer napping rooms in many U. S. cities. While resting in the middle of the work day may seem like a luxury to Americans, napping is very much part of a normal, everyday life in other parts of the world.

China, generally speaking, is a land of nappers. Researchers recently looked at information provided by nearly 3, 000 Chinese adults, aged 65 years or older. Based on their answers, researchers put them into four groups: non-nappers (0 minutes), short nappers (less than 30 minutes), moderate nappers (30-90minutes), and extended nappers (more than 90 minutes).

    The study found that the hour-long nappers did better on the tests than those who napped for shorter and longer periods. Keep in mind, however, that these are the findings for those over the age of 65.

    Michael Twery notes that an hour long nap may be too long for young, healthy adults. “Currently, 30 minutes is enough to remove the pressure to sleep and will help us feel more awake. If we nap longer, we will get trapped into sleep inertia—a very deep sleep period.”

The Benefits of Keeping a Journal

    If you want to grow, one important thing you should do is keeping a journal. It may seem simple, but it can make a big difference in your life. I have been keeping journals for years. Writing all the lessons I learn and all the ideas I get has become a habit for me. And to be honest, I can't imagine what my life would be like without it.

    {#blank#}1{#/blank#}

    It prevents you from losing an idea. Have you ever gotten an idea only to lose it later because you didn't write it down?{#blank#}2{#/blank#} But then I developed the habit of writing down every idea that came into my mind as soon as possible. If I'm away from my computer, I usually write it down on a piece of paper that I bring wherever I go. I will then transfer the idea to the journal in my computer.

    It helps you review all the lessons you've learned. By reviewing your journal, you can quickly see the lessons you've learned and the ideas you've gotten.{#blank#}3{#/blank#} You can use the ideas to propel (鞭策) yourself forward.

    {#blank#}4{#/blank#} After keeping a journal for years, you can look back at it and see how far you've gone. Things that were big problems in the past might seem small today. The raw ideas you had in the past might have been realized today.

    It helps you expand your ideas. When you try to come up with a sentence to express an idea, you are thinking actively about it.{#blank#}5{#/blank#} In the end, you will expand your ideas.

A. I often experienced that myself.

B. It trains you to express your thoughts.

E. Here are some benefits you will get by keeping a journal.

F. Thinking actively helps you connect your idea to another idea.

G. Then you can do whatever necessary to avoid repeating the same mistakes.

    Many Americans buy an evergreen tree for Christmas. They put the tree in their home and hang small lights and colorful things on it. The evergreen is usually a pine or a fir tree (冷杉树). It remains green during the cold, dark months of winter in the northern part of the world. So it is a sign of everlasting life.

    Early long ago, Romans probably planted evergreen trees during a celebration in honor of their god of agriculture. The Christmas tree may have developed from a popular play performed hundreds of years ago in what is now Germany. Traditionally, the play was on December 24th, the day before Christmas. The play was about the first people that God created—Adam and Eve. People put apples on an evergreen tree to represent the tree of knowledge in the Garden of Eden.

    By the year 1600, some Germans began bringing evergreen trees into their homes. They put fruit, nuts and sweets on the trees. They gave the food to the family members and friends after the holiday season. Some people say the German religious reformer (宗教改革者) Martin Luther was the first person to add lighted candles to the tree. They say he did this to show how wonderful the stars had appeared as he travelled one night.

    In the early 1800's, German settlers in the state of Pennsylvania were the first to celebrate the holiday with Christmas trees in the United States. The Christmas tree tradition spread to many parts of the world. Today, some form of the Christmas tree is part of most Christmas celebrations.
