    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.

    “I like photography because it captures amazing things that you might not see again,” Timmy Walsh says. He takes pictures of flowers, sunsets and road signs. But those photos don't usually end up in a scrapbook(剪贴簿) or on his bedroom walls.

    When Timmy was five, he found out that his aunt Bev had lung cancer. He wanted to do something to help her. His first idea was to sell his photos from a lemonade--type stand in front of his house in Pennsylvania. “My mom said it wouldn't work because we were not on a busy street,” Timmy explains.

    His next idea was to have an art show. Timmy decorated his home with candles, flowers, and white lights. Then he arranged his photos. Timmy's mom, Sheila, remembers: “Our dining-room table was filled, the living room—everything was filled with photos.” Friends, family, and Timmy's teachers came to the show. He raised more than $300 for cancer research that night. Aunt Bev was “very happy and excited,” he says.

    After a local newspaper wrote a story about Timmy's photos, a volunteer offered to help him set up a website. As people learned about his cause, called Camera for a Cure, Timmy began receiving invitations to sell his pictures at art galleries and fund-raisers. Since then, his work has appeared in more than 20 shows.

    When Timmy is at a show, he greets each customer and talks about what he was thinking when he took his photos. And he always shares facts about lung cancer. Sometimes donations and sales are slow, but that doesn't bother him. “It doesn't matter how much money we made because we just raised awareness,” he says. Timmy knows that finding a cure for lung cancer will take time and effort. So Timmy will keep doing his part by shooting and selling photos of the things he sees.

In a new move, doctors are using feature films in order to encourage their patients to talk more freely about their problems. Supporters of "film therapy (疗法)" say that discussing characters and plot lines from a proper film can help people to understand their feelings better.

One of those using the method is Bernie Wooder, a doctor from Elstree, who charges £45 for a one-hour "film therapy" session. He said, "I was treating a woman who had been badly let down in a relationship, and who was experiencing such strong feelings that it was difficult for her to speak about them. I told her that her situation reminded me of On the Waterfront, when Marlon Brando's character realizes his brother is dishonest and he feels a great sense of betrayal (背叛). My patient identified so easily with him that she started to cry. Watching and discussing the film unlocked all the feelings she had buried. Each time she watched and cried, she felt better."

Mr Wooder admits that film therapy does not work for everyone, but says he has used it successfully with about a third of his clients. "Through the films' characters, plots and even music, it allows people to face their problems." He said that Falling Down, in which Michael Douglas plays the part of an unemployed man who is so frustrated (沮丧的) that he uses violence, was an example of the dangerous implications (后果) of not letting anger go. "I used this film with a patient who was very upset because he was holding on to a lot of the anger he felt towards people who had frustrated him," said Mr Wooder. "We talked about Michael Douglas's character and the disastrous path he takes, and my patient then realized that he needed to let go of his feelings more regularly so as not to erupt (爆发) like a time bomb."

    Japan is very serious about robotics (机器人技术). If robots are going to fit in, they probably need to learn the Japanese custom of serving tea. Fortunately, researchers at the University of Tokyo are just exploring that. In a show this week, a humanoid(人形机器人)with camera eyes made by Kawada Industries Inc. poured tea from a bottle into a cup. Then another robot on wheels delivered the cup of tea in an experimental room that has sensors embedded in the floor and sofa as well as cameras on the ceiling, to simulate(模仿)life with robot technology.

    "A human being may be faster, but you'd have to say ‘Thank you'," said Professor Tomomasa Sato from the University of Tokyo. "That's the best part about a robot. You don't have to feel bad about asking it to do things."

    Sato believes Japan, a rapidly aging society where more than a fifth of the population is 65 or older, will lead the world in designing robots to care for the elderly, sick and bedridden(长期卧床的).

    Already, monitoring technologies, such as sensors that automatically turn on lights when people enter a room, are becoming widespread in Japan.

    The walking, child-size Asimo from Honda Motor Co. greets people at show-rooms. NEC Corp. has developed a smaller robot-on-wheels companion called Papero. A seal robot available since 2004 can entertain the elderly and others in need of fuzzy companionship.

    Sato says his experimental room is raising awareness about privacy questions that may arise when electronic devices(设备)monitor a person's movements down to the smallest detail.

    On the bright side, the tea-pouring humanoid has been programmed to do the dishes.

The True Story of a Young Man

When Reginald Lindsay received a scholarship to Morehouse College in Atlanta, Georgia in 1967, what he wanted most was not a job with a good salary, but a chance to be a member of Congress as a southern representative. After earning his degree at Harvard Law School in 1970, he returned to the South to practice law among the poor. "I want to help them understand what their rights are and to help them achieve them," he said. Then he ran for political office at the local and state level until he was ready to try for Congress.

Reg grew up in a low-income Negro section of Birmingham, Alabama. Brought up by his grandparents after his parents were divorced while he was very young, Reg had been living through a period of far-reaching progress in race relations. In the summer of 1968 Reg himself became a good example of this progress when he became the first Negro student appointed to a special new program. The program introduced bright young students to the workings of the Georgia State government and encouraged them to seek employment there after finishing their education. "I've been lucky," he said. "I seem to have been in the right place at the right time."

But luck was only part of Reg's story, for he made the most of opportunities that came his way. He learned to read in kindergarten and began visiting the public library regularly to borrow books. His grandparents encouraged him, though neither of them had much education, and they bought him a set of encyclopedias. "I loved those books," he remembered. "I used to come downstairs before breakfast and read short articles. I enjoyed reading about famous men, and then I would pretend to be one of them. I guess it was partly a childish game and partly an escape. It wasn't too much fun to be a Negro when I was a kid." While studying for his bachelor's degree at Morehouse College, Reg worked on several political campaigns helping candidates get elected to government offices. At the same time he maintained a "B" average while majoring in political science.

With just two more years to complete at Harvard Law School, which also gave him a scholarship, Reg made a good start on his professional career. He said, "The good life for me is the kind of life where I can find satisfaction in public service." Then in 1975 he was the Massachusetts state commissioner of public utilities and from 1993 to 2009 he was judge of the United States District Court for the District of Massachusetts.

    Raccoons are smaller relatives of bears. They are native to North America, but they can also be found in Asia and Europe. Raccoons live in wooded areas close to water, but they can be often found near urban areas. There are about 7 different species of raccoons. Pygmy raccoon is the only endangered species.

    Raccoons usually reach 40 to 70cm in length and weigh between 5­26kg. Raccoons that live in colder climates are larger and heavier. They have grayish fur, black masks around eyes and long tails covered with black and brown bands. Because of their tails, they are also called "ringtail".

    Raccoons are omnivores. They like to eat insects, eggs, small mammals, fruit, berries, garbage, and so on. Raccoon's hands look like human's. They each have five fingers and are used to collect food, open shells, door or trash cans. Raccoons often place food in water before they start to eat it. They have highly sensitive sense of touch and water increases their sensitivity even more. By touching the food, they get better insight about things they will eat.

    They are easily adaptable (适应的) to various environments. They can live in hollow (中空的) trees equally happily like they can in useless cars. Raccoons live on their own and hunt at night. They don't hibernate (冬眠), but they spend the coldest days of winters in their holes.

    Mating (交配) season takes place from January to mid March. Two months later, female will give birth to 3­4 babies. Their tails don't have bands, and the mask around eyes is still missing. Mother is very protective and she will teach them how to survive and what to eat as they become­ready to leave the hole. Raccoons usually can live only 1.8 to 3.1 years in the wild, but they can live up to 20 years at a zoo.

    Raccoons can pass rabies, a kind of disease, to home­raised animals and people, which is very dangerous. What's more, their waste often has roundworms.
