The introduction of the iPad,with its touch screen technology,has allowed even very young children to take advantage of a computer.So what if all children in a school were given an iPad to use in class and take home with them?

    Anne Laure Bazin works in a school where every child,teacher and teaching assistant is given a free iPad to use in and out of lessons.For her,the main advantage of everyone having an iPad had been the improvement in communication.Documents can be emailed straight over to workmates during a meeting.Children submit their homework by email,or through the school's learning environment.Teachers now take the register（点名）using their iPad,which means that there is a record of which children are in school,and which classroom they are in.

    The use of iPad has encouraged greater sharing of resources among teacher.All communication with parents is now done by email.Working as a group in class is much easier as children can share documents.The whole class can look at one child's work by attaching（连接）the iPad to the whiteboard.If a child has forgotten the textbook,the teacher can take a photograph of the relevant（相关的）page and send it to the student in class.

    While the use of the iPad in schools has revolutionized（变革）the way children are taught ,it hasn't completely replaced more traditional methods of teaching .Worksheets are still used in class as some children prefer the contact with paper.The children all have a textbook and exercise books.In Anne Laure's school,parents feared that the iPads would replace exercise books and children would lose handwriting skills.Anne Laure says,” The teacher are not ready to let go of the traditional style of teaching.We have welcomed the iPads in so much as they help communication and widen the resources available but we are not ready to let go of paper yet.The children themselves still value their exercise books and depend on them for review.”

    Scientists have found that human eyes are more likely to be damaged by UV rays (紫外线) while skiing in the snow-covered areas than sitting on the beach, according to a report by the UK newspaper The Telegraph.

    The researchers at Kanazawa Medical University, Japan and American company Johnson conducted the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail (a rough path) in Ishikawa District, northern Japan. They compared the results with the levels of UV rays on a sand beach in southern Japan's Okinawa District They found that on the beach, eyes are exposed to a daily 260 kilojoules (千焦耳) of UV a square meter compared to 658 kilojoules in snow-covered areas. The findings are supported by the Japan Meteorological Agency. According to the agency, the reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in lie new snow areas. The amount of light increased 4 percent with a 300-meter rise in height.

    Most of us know that UV rays can harm the skin. That's why we wear sunscreen on our skin before we get out in the suit. But many of us may not realize that UV rays are also harmful to the eyes.

    If your eyes are exposed to large amounts of UV radiation over a short period of time. You may experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes permanent damage to the eyes.

    Long-term exposure to UV radiation, however, can be more serious. Scientific studies and researches have shown that exposure to small amounts of UV radiation over a period of many years increases chance of eye damage, which could lead to total blindness.

    What do the world's most successful people all have in common?

    By examining the work habits of over 150 greatest writers and artists and scientist,the researchers including Stanford Professor Jeffrey Pfeffer found that high achievers like Robert Moses turn out to be all alike:

    Busy! Busy!

    {#blank#}1{#/blank#}In a study of general managers in industry,John Kotter reported that many of them worked 60 to 65 hours per week―which translates into at least six 10-hour days.The ability and willingness to work difficult and tiring hours has characterized many powerful figures.Energy and strength provide many advantages to those seeking to build power.

    Just Say No!

    The difference between successful people and very successful people is that very successful people say “no” to almost everything.And that's what gives them the time to accomplish so much.{#blank#}2{#/blank#}And focus means saying “no” to a lot of distractions.

    Know What You Are!

    Ignore your weakness and keep improving your strengths.Don't waste time exploring skill areas where you have little competence.Instead,focus on―and build on―your strengths{#blank#}3{#/blank#}

    Create Good Luck!

    Luck is not magical-there is a science to it.Richard Wiseman studied lucky people for his book Luck Factor,and broke down what they do right.{#blank#}4{#/blank#}By being more outgoing,open to a new ideas,following the feeling that something is true,being optimistic,lucky people create possibilities.

    Does applying these principles to your life actually work? Wiseman created a “luck school” to test the ideas―and it was a success.In total,80 percent of people who attended Luck School said that their luck had increased.{#blank#}5{#/blank#}

A. Spend enough time improving your weakness.

B. Achievement requires concentration.

C. On average, these people reported that their luck had risen by more than 40 percent.

D. High achievers never stop working and they never lose a minute.

E. Busy people are more likely to be lucky.

F. This means knowing who you are and what you are good at.

G. Certain personality types are luckier because they behave in a way that offers the chance for good opportunities.

    Injuries and deaths caused by driving after drinking are preventable. Sadly, actions by the police can only catch a small number of drunk drivers on the roads. It is up to each person to make the decisions.{#blank#}1{#/blank#}So we should help guide our friends and persuade them to avoid driving after drinking. Here are some tips.Start talking to the person early. With every drink, judgment becomes increasingly uncontrolled.{#blank#}2{#/blank#}So as soon as your friend starts drinking, you should try to persuade him to make a plan to get home safely. Remember, after he gets drunk, he may not listen to you.Help the person realize he is drunk. Talk to him and show him that he is increasingly clumsy.{#blank#}3{#/blank#}For example, ask who you can call to pick him up, or what public transport he would like to use. If he knows he is drunk, he may follow your advice.Make last efforts. If all else fails and a drunk person wants to drive home, threaten to call the police or take his keys.{#blank#}4{#/blank#}When he is not concentrated, take his keys. This may make it easier to convince him to take a cab home. Remember, don't give him the keys even if he's angry.{#blank#}5{#/blank#}If you once drove home after you got drunk, your friend may not listen to you. So in order to succeed in persuading your friend to avoid driving after drinking, you should behave yourself first.

A. Ask him where his keys are.

B. Set a good role model.

C. Give him an alternative way to get home.

D. But it isn't easy to make the right decisions.

E. Make him realize drinking makes him look like a fool.

F. The police will come to help you out once you call them.

G. It means the more one drinks, the less likely that he will listen to you.

    Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

    The first is called the "tank test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. Vne pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.

    The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot's job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.

    A new device (设备) called Orion is helping those who are blind to see. It does this in a new way by helping them experience the world around them.

    Jason Esterhuizen lost his eyesight after a car accident. He never thought he would be able to see light or movement again. But now with the movement of a switch (开关), his world suddenly grew brighter.

    He says, "I still can't put it into words. I mean from being able to see absolutely nothing, it's completely black, to all of a sudden seeing little flickers (闪烁) of light move around." It is not full or normal sight, but Esterhuizen can move about in the world around him.

    The new technology uses several parts. One is a small device placed in the brain. The other parts are a video camera on sunglasses and a processing device that can be carried in a person's clothes. When the user points the camera, a signal goes to the processor (处理器) and then back to the glasses. The glasses then are in wireless communication with the device in the brain. The information causes a pattern to develop in the part of the brain. The pattern helps users sense or see movement and shapes of light. And it all happens in seconds.

    Esterhuizen is one of just two people in the U.S. testing this technology. He says that "I can tell someone moving across the room, walking past me or walking away from me, or it's a light against the wall. It is just amazing to have some form of functional vision again." He adds that now he can do everyday activities around his home that he once could not. It is easier to walk outside.

    The researchers believe that one day this technology could help people who have lost their vision because of illnesses like diabetes. It may also help those with poor vision or who were born blind.
