Have you ever noticed what happens to an idea once you express it?Just talking about it or writing it down causes you to make it clear in your own mind.How can you use this to increase your brain power?Start writing.

    By putting thoughts into words,you are telling yourself the logic behind what you think,feel,or only partly understand.Often,explaining a thought is the process of understanding.In other words,you increase your brain power by exercising your “explain power”.

    Another benefit of writing is that it helps you remember.Many,if not most,highly productive people are always taking notes.You can try keeping it all in your head,but if you keep a journal of your ideas,the next time you're working on a big project,you'll probably have more success.

    Want to understand a topic?Write a book about it.That's an extreme example,but if you are learning something new,write a letter to a friend about it,and you will understand it better.Want to invent something?Write an explanation of the problem—why you want to solve it,and why it is worth solving,and you're halfway there.

    Writers don't always write because they clearly understand something beforehand.Often,they write about something because they want to understand it.You can do the same.Writing will help bring you to an understanding. Give it a try.

    Cosmetic surgery (整容手术) is not something to be entered into lightly. Unfortunately, in this modern world, we have become confused by very narrow standards of beauty. Images of stars who never seem to age are seen everywhere these days. We forget the fact that most of these images are the result of super photo manipulation (处理), driven by the extremely powerful beauty industry. We are all different — why should we all look the same? Isn't there more to life than having surgery in order to have the same boring face that everybody else wants to have?

    Yes, it's not real! That's what I told my friends when they started asking me about my nose job. I'd always been sensitive to my nose, but it took me a long time before I decided to go for cosmetic surgery. I took advice from several doctors and after careful consideration I finally decided to have it done. I had been saving money from my part-time job and my parents helped me out with the rest. It was quite expensive but I don't regret a penny of it. In fact I wish I'd had it done a few years ago. I' m sure I wouldn't have been laughed at so much at school.

    It makes me really angry to think of the millions of people who spend much money on cosmetic surgery. Surgery should be carried out for medical purposes, not vanity (虚荣心). I would rather all the money spent on cosmetic surgery was used to treat people around the world who are in need but can't get proper medical treatment. Furthermore, there are thousands of under-qualified doctors out there who only care about getting as rich as possible as quickly as possible. They don't care about the psychological and physical damage they do. The whole industry makes me sick. We should do something to stop it.

    Imagine the tallest building in the United States. Fill that giant building 44 times with rotten fruits and vegetables. Now you know how much food Americans waste every year.

    It is hard to believe, right? About 133 billion pounds of food get thrown away. That's one-third of all the food we produce. And a lot of it is thrown away for one simple reason: It's ugly.

    The problem is that nature isn't perfect. Apples can get scarred (留下疤痕) by storms. Cucumbers grow in C shapes. Carrots change into unusual fork-like forms. Watermelons get too big to fit on a refrigerator shelf. These crazy-looking fruits and vegetables may taste great. But most grocery stores refuse to sell them. Store owners say people judge food by how it looks. No one wants a tomato that looks like a two-headed monster. But what if you could buy that tomato for half-price?

    A new movement is trying to make people see the “beauty” in ugly food. Some stores are selling ugly produce. It tastes the same. And you pay less for it because the food doesn't look perfect.

    Usually, the stores find a nicer word than “ugly”. A Canadian chain uses “naturally imperfect”. In some US stores, it's “misfit produce”. Whatever you call it, ugly food helps many people. Fanners get paid for food they were going to have to throw away. Shoppers get cheaper fruits and vegetables. The ugly-food movement will also help some of the 44 million Americans who don't have enough to eat. Many groups give the ugly produce to hungry people.

    So really, who cares if that carrot looks a little… ugly?

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple — eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be so-called similarity attraction theory — where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV — where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble (咬), while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions (交易) from the start.”

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, “This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful.”

    In 2012 my wife and I decided to open our bookstore in spite of unfavorable situations. The challenges facing small bookstores were-and remain-significant. Apart from the obvious rise in online selling, the increase in the popularity of e-books has negatively affected independent providers.

    The question is why a new, small-scale（小规模的）provide would voluntarily enter such a challenging market? From a personal view, our reasoning was sound: we wanted to share our love of great books and reading for pleasure with as many like-minded people as possible.

    Having done our homework, one thing became clear. In order for us to succeed, we would have to offer something that none of our larger competitors already provided. And so we started the Willoughby Book Club. We set up our website in the summer of 2012, and we haven't looked back.

    The idea of service is simple. We offer a range of book subscription gift packages, available in three-month, six-month and 12-month options. Our customers choose a package, tell us a little about the person they're buying it for, and we use this information to send the receiver a hand-picked, gift-wrapped book once a month. We also recently decided to give one new book to Book Aid International for every gift subscription sold. These books are sent out to sub-Saharan Africa, supporting the educational work there. Within four months of starting out, we won the Young Bookseller of the Year Award at the 2013 Bookseller awards.

    Our brief journey from new booksellers to award receivers has been challenging and rewarding. The biggest thing we've learned is that, despite the pressures facing independent providers, there is a place for them in the UK market. It's just a question of finding it.

    Millions of Americans sit behind a computer screen, chained to their desk all day because the vast majority of stable, high-paying professions(职业) are "office jobs". However, having a successful career does not require you to sit behind a desk and plug away at a computer all day.

    In fact, there are a large number of non-desk jobs in a variety of industries that are growing and offering workers a direct path to the middle class, according to a new analysis of labor market information from CareerBuilder. While most of the highest-paying non-desk jobs are medical professions that require a doctoral or professional degree, there are 170 non-desk professions that pay $15 per hour or more, do not require a bachelor's degree(学士学位) for a typical entry-level position, and have seen at least 6 percent job growth over the last four years.

    "The US workforce has gradually changed to office-based work because of the rise of the professional service economy and productivity gains associated with information technology," Rosemary Haefner, Vice President of Human Resources Officer at CareerBuilder, said in a statement. "But some of the healthiest areas of job growth year after year are in middle-skill professions that don't require workers to sit in front of computer monitors and phones for 40 hours a weel."

    Here are the top-paying jobs that don't require you to work at a desk in various kinds — none of which require a four-year college degree — and their hourly salary(工资) and growth rate since 2010: professional assistants(助理) : $26.57, 14 percent; elevator repairers: $37.81, 6 percent; mechanical engineering technicians: $25.19, 10 percent; and electromechanical(电动机械的) technicians: $24.68, 8 percent.

    While they tend to pay less than traditional office jobs, non-desk professions provide a variety of benefits. Haefner points to a 2014 CareerBuilder survey that discovered workers who don't work at a desk all day are less likely to complain about their work environment and less likely to report being overweight.
