Bethany Hamilton is a professional surfer (职业冲浪手) in America. Her parents are both surfing lovers. As a baby, Bethany liked to play in the water. She started surfing at the age of five. By thirteen, she had been one of the best teenage surfers in the world. Then the shark attack (鲨鱼袭击) happened.

    On the morning of October 31, 2003, Bethany and some friends decided to go surfing. The sky was clear, and the sun was shining. The 13-year-old surfing star was lying on her surfboard (躺在她的冲浪板上) with her left arm in the clear, blue water. Suddenly a five-meter shark appeared and attacked her. Bethany saw the water around her tum red. She held on to her board and the shark swam away -- but it took her left arm with it. Luckily, the shark attacked only once. It all happened so fast that she didn't even shout.

    In her mind, Bethany thought, "Get to the beach. Get to the beach." She started to swim with one arm. She shouted for help. Her friends didn't know about the shark attack -- they thought at first that she was joking. Then they saw the red water and quickly came to help. It took her about fifteen minutes to reach the beach. They called 911 and. Bethany got to hospital at last. Surprisingly, she was surfing again in a competition only ten weeks later. And less than a year after the shark attack, she won first place in a surfing competition in Hawaii.

    Students spend more time at school than anywhere else. At school, children need a safe and comfortable environment to help them learn. By doing the following, parents can help make sure children have a good school life.

    {#blank#}1{#/blank#}. Ask your children if they see anyone bullied(被欺负), if they are bullied, or if anything else makes them feel uncomfortable. Look for warning signs, such as a sudden drop in grades or a loss of friends.

    {#blank#}2{#/blank#}. Tell children that fighting could lead to them getting hurt, or hurting someone else. Tell them about other ways they can solve a problem, such as walking away or telling to teachers or the adult you know well.

    {#blank#}3{#/blank#}. Talk to your children about what they do online—what websites they visit, who they email, and who they chat with. Let them know they can talk to you if anything they see online makes them uncomfortable.

    {#blank#}4{#/blank#}. Teach children to follow traffic lights and rules when walking or biking. Stress that they should cross the street at crosswalks.

    {#blank#}5{#/blank#}. Don't go anywhere with them, or accept gifts from them when you don't know. If they see a stranger hanging around or in their school, they should tell the people that you know.

    Have you ever counted the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. That's because China has the longest mobile phone numbers in the world. Why is that?

    The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service provider (提供者) you are using For example, 135 is for China Mobile Communications Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you where the number is registered (注册). And the last four digits are random (随机的).

    The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999. Eleven digits can be used to make tens of billions of mobile phone numbers. That's enough for each person to have seven or eight phone numbers to use in China.

    And mobile phone numbers can be recycled. Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven't contacted (联系) for a long time, you may find that its owner has changed.

    Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada's mobile phone numbers are perhaps the shortest in the world: they use seven digits.

    You don't need to get in a time-travelling machine to see how technology will change our lives, such as the way we shop. Several new technologies that are to change your buying habits already appear. Let's see what's in store for your future shopping.

Try it on, virtually(虚拟地). Want to shop online for a new pair of glasses? You don't need to guess which pair looks best on you一 use the eBay Fashion iPhone app to try a pair of glasses you re checking out on a picture of your face. But what about buying something bigger? Thanks to Microsoft Kindest s action tracking(跟踪) camera, you can cover clothes on your screen body. You can even choose the background of your virtual fitting room to improve your shopping experience.

    Get a perfect, custom fit. Everyone's body is shaped differently. To get a perfect fit, you sometimes have to get your clothes changed. But by using 3D scanning(扫描) technology, all the clothes you buy will fit your body perfectly. Some companies scan your body using high-tech to get the real sizes, so they can make special clothes just for you.

    High-tech shopping carts(推车) and checkout counters(收银台). High- tech shopping carts could be common in malls and supermarkets in the future. Microsoft Kinect-enabled carts are under test. The cart can follow you along the aisles(通道), controlled only by your movement and your voice.

    In the United States, several supermarkets use a certain set called "Scan It" that gives buyers the freedom to scan products on their own while they shop. If we don't want to wait in line before the checkout counters, we can use Toshiba's new Object Recognition Scanner. The machine identifies(辨认) a product as soon as it's placed in front of a camera just by its shape and colour, even if it has no bar code.
