    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.

    LEEDS, England—A Leeds University psychology professor is teaching a course to help dozens of Britons forgive their enemies.

    “The hatred we hold within us is a tumor,” Professor Ken Hart said, adding that it can lead to problems such as high blood pressure and heart disease. More than 70 people have become members in Hart's first 20-week workshop in London—a course he says is the first of its kind in the world.

    “These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves,” said Canadian-born Hart.

    The students meet in groups of eight to ten for a two-hour workshop with an adviser every fortnight. The course, ending in July, is expected to get rid of the tumor of hatred in these people. “People have lots of negative attitudes towards forgiveness,” he said, “People confuse forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one." Hart and his team have created instructions to provide the training needed.

    “The main idea is to give you guidelines on how to look at various kinds of angers and how they affect you, and how to change your attitudes towards the person you are angry with," said Norman Claringbull, a senior expert on the forgiveness project.

    Hart said he believes forgiveness is a skill that can be taught, as these people “want to get free of the past”.

    Since Abbi Hickman was just a little girl, she has been surrounded by animals. Chickens, cats, dogs, rabbits, and sometimes goats are just some of the animals she cares for. At the age of 9, Abbi went to the Tracy Animal Shelter，in her hometown of Tracy，California，to adopt Sheldon，her favorite cat. There，she saw the poor conditions that the animals were kept in. Abbi knew that it was her duty to take action.

    Pins for Pets is Abbi's solution. For the last three years, she has organized a bowling tournament to raise funds for the Tracy Animal Shelter. She has raised more than $30,000, resulting in a better home for the animals. “Now the shelter is nicer and cleaner and animals have more space. It is far better, a hundred percent better,” Abbi says.

    To praise Abbi for her outstanding efforts, the American Society for the Prevention of Cruelty to Animals (ASPCA) named her the 2015 ASPCA Tommy P. Monahan Kid of the Year. This award is given to kids who make a substantial (大量的) effort to help animals. Abbi responded to the news of her win with shock. “I was pretty excited. I' m really honored to receive it,” she says.

    Sacrificing time and effort to assist animals can sometimes be difficult, but Abbi hopes to do more. “I want to spread my free services to more shelters. I really just hope people are kinder to animals and respect them more,” says Abbi, sharing her goals for her organization.

    At the age of 12, Abbi has already accomplished so much. The advice she has for kids like her, who want to accomplish their goals, is, “Nothing is impossible. You can do anything you put your mind to. Even if it is something small, it can make a huge difference.” Abbi's work has improved the lives of animals, and she plans to keep coming up with new ways to help them.

    Aging brings wrinkles, sagging bodies and frustrating forgetfulness. But getting older is not all bad for many people. Mounting evidence suggests aging may be a key to happiness. There is conflicting research on the subject, however, and experts say it may all boil down to this: Attitude is everything.

    Older adults tend to be more optimistic and have a more positive outlook on life than their younger and stressed opposites. The big question is why seniors are happier. A recent study suggests one reason: Older adults remember the past through happy memories. Aging can bring more cheer as people become more comfortable with themselves and their roles in society. The older adults said they were enjoying more time with their family, spending more time on hobbies and having greater financial security and did not have to work.

    But others are doubtful about the link between happiness and growing older.

    "The notion that those in old age are happiest is misleading," said Richard Easterlin, a professor of economics at the University of Southern California. "It is based on comparing people of different ages who are the same in terms of income, health, family life." Easterlin added, "When you take account of the fact that older people have lower income than younger, are less healthy, and more likely to be living alone, then you will find it hard to accept that they are happier.

    In fact, scientists have found that as people age, their health declines and social networks disappear as their friends die, which can make the elderly less happy.

    Even if one does give in to age's dark side, health and happiness don't always go hand-in-hand. It's all about attitude. Research by the University of Chicago's Yang suggests that attitude about life and happiness, is partly shaped by the era in which a person was born. It turns out that individuals who adapt the best to changes also have the highest expected levels of happiness.

 Despite the conflicting findings about aging and happiness, the good news is that there doesn't appear to be a limit to how much happiness one can achieve in one's life. “Most people desire happiness,” Easterlin said. “To my knowledge, no one has identified a limit to attainable happiness.”

    Cities usually have a good reason for being where they are, like a nearby port or river. People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness(荒野). But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.

    Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snow-covered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warming. An avalanche(雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.

    But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.

    It is back to school time in the United States, which for children is bittersweet. The bitter part is saying goodbye to carefree, unscheduled summer days. The sweet part is saying hello to a new school year and school friends.

    This exciting time is filled with smells of new books, paper and pencils. Children might be dressed in a new set of clothes and wear new shoes.

    However, going back to school can also be a stressful time for children and families. Everyone must make the change from easy summer life to routines, schedules and homework. Families might also feel stress about spending extra money for a new school year.

    Back-to-school stress is different for different grades of students. Younger children may feel scared to leave their families. Making new friends and dealing with bullying(欺负) can also cause stress for students. Older students may feel stressed about their appearances, grades and getting into college.

    However, teachers and children can all help to make the transition back to school easier. Lori Bambina has been a teacher for 22 years. She focuses on the class routine during the start of the new school year.

    "Well, for the students, I have my classroom set up with a very clear system. So I will introduce the system. Then I will revisit the system because at this young age they enjoy structure and predictability. And that routine is very comforting and will not cause them to feel stressed if they know exactly where things are located and what type of behavior is expected. That really reduces the stress and the anxiety because they have their own comfort level now," she said.

    Whether you are in the 1st grade or 10th grade, knowing what your teachers expect is a good way to reduce stress.
