    Suppose you're in a rush, felling tired, not paying attention to your screen, and you send an email that could get you in trouble.

    Realisation will probably set in seconds after you've clicked “send”. You freeze in horrors and burn with shame.

    What to do? Here are four common email accidents, and how to recover.

    Clicking “send” too soon

    Don't waste your time trying to find out if the receivers has read it yet. Write another email as swiftly as you can and send it with a brief explaining that this is the correct version and the previous version should be ignored.

    Writing the wrong name

    The sooner you notice, the better. Respond quickly and briefly, apologizing for your mistake. Keep the tone measured: don't handle it too lightly, as people can be offered, especially if your error suggests a misunderstanding of their culture(i.e. incorrect ordering of Chinese names).

    Clicking “reply all” unintentionally

    You accidentally reveal(透露)to entire company what menu choices you would prefer at the staff Christmas dinner, or what holiday you'd like to take. In this instance, the best solution is to send a quick, light-hearted apology to explain your awkwardness. But it can quickly rise to something worse, when everyone starts hitting “reply all” to join in a long and unpleasant conversation. In this instance, step away from your keyboard to allow everyone to calm down.

    Sending an offensive message to its subject

    The most awkward email mistake is usually committed in anger. You write an unkind message about someone, intending to send it to a friend, but accidentally send it to the person you're discussing. In that case, ask to speak in person as soon as possible and say sorry. Explain your frustrations calmly and sensibly—see it as an opportunity to clear up any difficulties you may have with this person.

    A new technology is going to ripe, one that could transform our daily lives, help to form new industries, even remove world economic powers from their present positions. Unlike the wave of industrialization that began in the West and spread later to the rest of the world, the new developments are taking place in research labs all over the globe—and Asians are in the forefront. Physicists are creating a new class of materials that display an amazing property unforeseen even two years ago—superconductivity (超导体技术).

    Used today only in specialized equipment, super conductors have the potential to radically change most of the electrical and electronic appliances found in the home, making them smaller, more powerful and efficient. They could free our cities of pollution by replacing petrol and diesel (柴油) vehicles with electric cars, and cut the cost of electricity. The new materials do something that even the best of conductors such as copper and silver cannot—they do away with all electrical resistance. The significances for energy storage are great.

    The technology is in its early stage, still accessible to countries that decide to invest brains and money. For 75 years it had remained little more than a scientific curiosity with limited practical use because the phenomenon occurred only at extremely low temperatures. It was first observed in 1911 by a Dutch scientist named Heike Kamerlingh Onnes, who cooled mercury (水银) to temperatures below -269℃ with liquid helium (氦). Then in January last year, two IBM scientists, K. Alex Muller and J. George Bednorz, found a metal oxide ceramic (氧化陶瓷) that superconducted at -243℃. Their report went largely unnoticed until last December, when it was confirmed at a scientific meeting in Boston. Today Japan, India, China and other Asian countries all have their share of experts who spend their days and nights in labs, acting as midwives (助产士) to a new technology.

    Monthly Talks at London Canal Museum

    Our monthly talks start at 19:30 on the first Thursday of each month except August.

    Admission is at normal charges and you don't need to book. They end around 21:00.

    November 7^th

    The Canal Pioneers, by Chris Lewis. James Brindley is recognized as one of the leading early canal engineers. He was also a major player in training others in the art of canal planning and building. Chris Lewis will explain how Brindley made a positive contribution to the education of that group of early “civil engineers”.

    December 5th

    Ice for the Metropolis, by Malcolm Tucker. Well before the arrival of freezers, there was a demand for ice for food preservation and catering, Malcolm will explain the history of importing natural ice and the technology of building ice wells, and how London's ice trade grew.

    February 6^th

    An Update on the Cotsword Canals, by Liz Payne. The Stroudwater Canal is moving towards reopening. The Thames and Severn Canal will take a little longer. We will have a report on the present state of play.

    March 6^th

    Eyots and Aits—Thames Islands, by Miranda Vickers. The Thames had many islands. Miranda has undertaken a review of all of them. She will tell us about those of greatest interest.

    How do young children learn to have good values? How can parents teach their children about the importance of kindness and patience? At a time more and more parents worry about the violent images (暴力形象) their children see on TV and on the Internet. So many parents are turning to fairy tales. They want to teach their children how to behave in society by this way.

    It is believed that fairy tales have a great influence on children because they describe the two sides of good and evil (邪恶) very clearly. When children hear the tales, they learn to care about others' feelings. In each tale, they can see that there are many different kinds of people in the world and that we all have a choice about what kind of person we want to be. We can choose to do good actions, rather than bad ones, in our lives.

    What kind of values can children learn from fairy tales? In The Princess and the Pea, a poorly dressed girl says she is a princess. Few people believe her, so she is given a difficult test. When she passes the test, we learn that her dream comes true because she stays true to herself. In the Little Mermaid (《小美人鱼》), the mermaid, who lives under the sea, wishes to be with the humans on land. Through her experiences, we learn about the importance of living with and accepting other cultures.

    Teaching values is probably the main reason for encouraging children to read fairy tales. These tales can teach children lessons about human relationships that have been accepted around the world for many centuries. This might be the reason why they have been around for so long and will not disappear any time soon.

    Daniella was brushing her daughter's long brown hair when she noticed that bunches of it were coming out. That was January 1, 2017. Within 20 days, seven-year-old Gianessa's hair and eyebrows were completely gone, and her doctor said they would never grow back. Gianessa had become one of the 6.8 million Americans with alopecia, a disease that causes hair loss.

    Alopecia isn't painful, but for kids who suffer from it, the acute mental pain comes from standing out from the crowd. For the most part, the students in Gianessa's first-grade class in Salem, Utah, were understanding. But occasionally, she still felt like an outcast(被排斥者). "I did not want her to not feel beautiful," her mother told Today.

    Then the school announced its "Crazy Hair Day" competition in April, and Daniella and Gianessa decided that rather than hiding Gianessa's baldness(光头), they would celebrate it. Daniella bought sticker jewels and decorated her daughter's head with colorful designs. "They just fit her personality," Daniella told CNN. "She's so full of life."

    On the morning of the competition, Gianessa was nervous. Would her friends think it was funny? She had nothing to fear. Gianessa was a hit—and the winner of the crazy-hair competition. Gianessa is now glad she dared to go bare. "I was sad at first when I lost all my hair," she told People, "but now I love being bald. I can do things to my head that other kids can't. I'm thinking now it might be fun to decorate my head with some shiny butterflies and flowers."
