        A small school in rural India is gaining attention over the fact that all 300 students are ambidextrous(左右手都灵巧的). Data shows that only one percent of the global population is ambidextrous, but the ambitious founder of Veena Vandini School, in Madhya Pradesh, is aiming to change that, starting at a local level.

        A former soldier and Veena Vandini School founder VP Sharma stated that he was inspired to focus on ambidexterity training by India's first president Rajendra Prasad who was in office from 1950 to 1962. Unexpectedly, the president was ambidextrous. "I read in a magazine that Dr. Rajendra Prasad, India's first president, used to write with both hands. This inspired me to give it a try, “Mr. Sharma said.”Later when I launched my school at my native village, I tried training the students. "

        "We begin training students from standard Ⅰ and by the time they reach standard Ⅲ, they are comfortable writing with both the hands,” Sharma added. "Students of up to standard Ⅶ can write with speed and accuracy. Further, they can write two scripts at the same time, one with each hand. Students also know several languages, including Urdu."

        Every 45-minute class at Veena Vandini includes 15 minutes devoted to handwriting practice, ensuring that every student develops the ability to write with both hands. VP Sharma also believes that the skill better enables students to learn multiple languages, and has them practice writing the same words in different languages at the same time. Although it is widely believed to help increase concentration, more recent studies have found that this is false and studying to become ambidextrous can, in fact, harm cognitive development.

        A Scientific American study revealed that ambidextrous children performed worse than left- or right-handers on a range of skills, especially in math, memory, and logical reasoning. A study in northern Finland indicated that children who are ambidextrous are much likelier to develop mental health issues, including ADHD, language problems, and academic problems.

    (1)What is special about Veena Vandini School?
    A . It only accepts 300 students yearly. B . It was set up by India's first president. C . It mainly teaches how to write with both hands. D . It requires students to learn practical living skills
    【答案】
    (2)In which standard can students write quickly and accurately?
    A . Standard Ⅲ. B . Standard Ⅳ. C . Standard Ⅵ. D . Standard Ⅶ.
    【答案】
    (3)What might most people think of the skill promoted by VP Sharma?
    A . It helps students fix their attention. B . It does harm to students' creativity. C . It increases students' academic stress. D . It inspires students to learn more languages.
    【答案】
    (4)What do the two studies suggest in the last paragraph?
    A . Kids are reluctant to write with both hands. B . Kids shouldn't learn to write with both hands. C . Kids who are ambidextrous always fail in the math test. D . Kids who are ambidextrous often have serious mental illness

        Next time you hear a funny joke you'd better not laugh too hard. According to a paper published by the British Medical Journal, laughter isn't always the best medicine. Sometimes it can even be harmful. Professor Robin Ferner from the University of Birmingham, one of the authors of the study, found that bad things could happen to people who laughed too much. He says, "We found people with heartbeat problems which had stopped their hearts, we found people who had fainted(昏倒), and we found people who'd dislocated their jaws or burst their lungs."

        It seems that laughing can be no laughing matter. But it's not all doom and gloom. Professor Ferner says there are benefits to laughing when you want to lose weight, for example. Yes, that's right: laugh and be slimmer! Professor Ferner explains that: "You use energy when you laugh, you move your diaphragm(横隔膜), you expand your lungs, and both those things can be helpful."

        According to the research, laughing for a quarter of an hour can burn 40 calories, and if you laughed all day you'd use about 2, 000 calories, which is what most people consume in a day. But don't do that or you might end up with a painful jaw. Ouch! Or you might find people looking at you in a funny way.

        But I don't want to finish this article leaving you feeling desperate. Laughter comes naturally for most of us. Babies begin to laugh at around 3-6 months. So give in to your sense of humour and keep smiling. Life is short anyway.

    Help Hermit Crabs

        Hermit crabs are nature's recyclers. They eat waste and help keep oceans and shores clean. Unlike other crabs, the hermit crab has a thin outer shell over its soft tail. This makes the hermit crab easy prey for hungry predators(天敌).Hermit crabs stay safe by living in old seashells. A hermit crab is picky(狡猾); it tries on many shells until it finds one that fits just right. In recent years, however, many hermit crabs have had trouble finding their perfect homes. What is the problems. There are not enough shells to go around!

        One reason for the seashell shortage is that ocean water is not as clean as it once was. This has caused chemical changes to sea water. Some sea animals, like snails, are affected by these changes.  Now there are fewer snails making shells. People visiting the beach often take shells home as souvenirs(纪念品).This is another problem. Other people even take shells for their own pet hermit crabs! They do not realize that hermit crabs in the wild need those shells too.

        Now people are working to solve this hermit crab housing shortage. They are teaching beach-Boers to leave seashells where they belong--at the seashore! Some people even make fake seashells that they hope the hermit crabs will like. For example, a group called Project Shelter invited people who visited their website to create different designs for hermit crab shells.

        These designers had a lot to consider. What kind of material should be used to build a seashells. The material must be light enough for the hermit crab to carry, but strong enough to protect the crab from predators. The man-made shells could not contain glue or any other substance(物质)that might harm a hermit crab. Another challenge with building a hermit crab home was the opening to the shell. Too big would mean the crab would not feel safe. Too small would be uncomfortable, and the crab would not want to move in.

        The Project Shelter shells are placed in the wild for hermit crabs to find. Lucky hermit crabs can move into these new dream homes.

        Artificial intelligence (AI) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like breast cancer in ways that were never before possible.

        Rishi Rawat teaches AI at the University of Southern California's (USC) Clinical Science Center in Los Angeles. He is part of a team of scientists who are researching how AI and machine learning can more easily recognize cancerous growths in the breast. Rawat provides information about cancer cells to a computer. He says this data helps the machine learn." You can put the data into computers and they will learn the patterns and the pattern recognition is important to making decisions."

        David Agus is another USC researcher. He says machines are not going to take the place of doctors. "Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can't recognize by itself. Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer."

        Currently, researchers take a thin piece of tissue, put it on a small piece of glass and add color to better see the cells. That process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns, or structures, and learn how the cells are organized.

        The hope is that machines will soon be able to make a quick identification of cancer that is free of human mistakes. "All of a sudden, we have the computing power to really do it in real time. We couldn't have done this, we didn't have the computing power to do this several years ago, but now it's all changed." Agus adds that the process could be done for almost no cost in the developing world. He says that having a large amount of information about patients is important for a machine to effectively do its job in medicine.

        The University of Southern California researchers are now only studying breast cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.

    Choose the one that fits best according to the information given in the passage you have just read.

        The American Craftsman style is a type of design. It was popular from 1900 to the 1930s. It changed the style of building in the United States.

        The craftsman style originally began in Europe. The British Arts and Crafts style arose in the 1860s. The unique designs of this movement tried to offer dignity to the common person. Handmade items were preferred because they were thought better than items that were mass-produced. But this British style was still Victorian. It still only served the wealthiest clients.

        In 1897 a group of Boston architects brought these handcrafted styles to American. They planned a show of craft objects, which turned out to be a huge success. Here they realized the potential and established the Society of Arts and Crafts on June 28, 1897. Its slogan was "to develop and encourage higher standards in the handicrafts."

        The American style began as the Victorian Era was ending. It emphasized handmade work. Originality and simplicity were highly valued. Local materials and the quality of the handicraft were very important, these traits were meant to dignify the modest homes of the middle class.

        These simple designs used glass and wood that were produced locally. They were also very elegant. The metalwork was a reaction to Victorian Opulence. The increase of mass-produced housing items was rejected. The American Craftsman used clean lines. It also relied on sturdy structure. Natural materials were always used in these houses if possible.

        This style introduced many changes to the average American home. New designs were made for families without servants. This was a trait of the new middle class. The kitchen went from being a hidden room to a prominent one. Another development was the breakfast nook. This new area provided the family with a place to gather at any time of day.

        Also, inspirational to the Craftsman style were the Shaker and Mission designs. The American Craftsman style led to the Art Deco Movement of the 1930s.

        Facebook says it is working on technology to allow us to control computers directly with our brains. It is developing "silent speech "software to allow people to type at a rate of 100 words per minute, it says. The project, in its early stages, will require new technology to detect brainwaves without needing invasive operation. "We are not talking about monitoring your random thoughts," assured Facebook's Regina Dugan. "You have many thoughts, and you choose to share some of them. We're talking about monitoring those words. A silent speech interface(界面)-one with all the speed and flexibility(灵活)of voice. "

        Ms Dugan is the company's head of Building 8, the firm's hardware research lab. The company said it intends to build both the hardware and software to achieve its goal, and has employed a team of more than 60 scientists and academics to work on the project.

        On his Facebook page, Mark Zuckerberg added, "Our brains produce enough data to stream four HD(高清)movies every second. The problem is that the best way we have to get information out into the world-speech-can only send about the same amount of data as a 1980s modem. We're working on a system that will let you type straight from your brain about five times faster than you can type on your phone today. Finally, we want to turn it into a wearable technology that can be produced in quantity. "

        Technology is going to have to get a lot more advanced before we can share a pure thought or feeling. but this is a first step. Other ideas detailed at the company's developers conference in San Jose included work to allow people to "hear" through skin. The system, comparable to Braille, uses pressure points on the skin to pass information. "One day, not so far away, it may be possible for me to think in Chinese, and you to feel it instantly in Spanish,"Ms Dugan said.

    At age 22, Hikari Oberman has already been a lifeguard for four years. Last week, Oberman talked to The Garden Island about how he helped save lives during a recent rescue.

    On Dec. 30, Oberman and his coworker Cope were parked in their truck at Anini Beach when two workers ran up to them and said, "I think someone's getting stuck in the channel!"

    "I grabbed our equipment. We started rolling out down there," Oberman said. When he got out there, Oberman found a standup paddler, a man in his late 30s, struggling against the current, with an elderly man holding tightly to the back of the paddleboard (冲浪板).

    He said, "My coworker grabbed the standup guy. Meanwhile, I'm stuck with the older man. "

    Normally, Oberman said he would pull the paddler up, lay him on the surfboard, climb up behind and paddle from there. He tried that technique at first and quickly realized it was not a practicable option. They are not going anywhere.

    Waves hit against the extremely sharp reef very hard about 30 yards behind them, and the current was pulling them into it.

    "It's right behind us. If I stop paddling, we're definitely going to be in that zone." He said.

    They started making progress toward the reef, where they might safely be able to climb out. Oberman just focused on forward movement.

    After about five minutes-"even though it felt longer" -Oberman said his partner had gotten the paddleboarder safely to shore and started coming back out to help.

    "I look back, and I see our Jet Ski. He's finally coming in the channel. We're not going to have to worry about that now. "

    It was a good rescue.

    When asked what it feels like to save someone's life, Oberman responded, "I love it! That's why we do it!" But as exciting as it might be to perform a big rescue, he explained that the most important part of his job is to keep people from getting into trouble in the first place.
