If you have ever been left wondering why your emails are riddled(充斥着) with grammatical errors, or why you can never quite find the right phrase, it may be because you are typing with both hands.

    Our vocabulary becomes richer and our writing style becomes more fluent when we type using just one hand, scientists have found. "Typing can be too fluent or too fast, and it can actually weaken the writing process," said Srdan Medimorec, the lead author of the study conducted at the department of psychology at the University of Waterloo, Canada. "It seems that what we write is a product of the interaction(互动) between our thoughts and the tools we use to express them."

    Using text-analysis software, researchers asked 103 university students to write essays under different conditions, using one hand to type and using both hands to type. The software was used to analyze(分析) elements of the essays, such as range of vocabulary, sentence complexity and the cohesion(衔接) of the writing.

    Researchers found that participants' vocabulary became more advanced when they typed with one hand rather than two. The research team said that by slowing our writing down, typing one-handed allows more time for an internal (内在的) word search, resulting in a larger variety of words.

    In contrast, fast typists might just write the first word that comes to mind. However, it is important not to slow typing down too much. Those who typed essays one-handed in the current study slowed down to about the speed of handwriting.

    This is the first study to show that changing people's typing can make their writing get better. The researchers suggested that the speed of writing could affect writing quality regardless of the tools used, whether they are computers, or pen and paper, although further research would be required to prove that idea.

    It was the summer of 1965. DeLuca, then 17, visited Peter Buck, a family friend. Buck asked DeLuca about his plans for the future. “I'm going to college, but I need a way to pay for it,” DeLuca recalls saying. “Buck said, 'You should open a sandwich shop.' ”

    That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, Buck wrote a check for $1000. DeLuca rented a storefront(店面) in Connecticut, and when they couldn't cover their start-up costs, Buck kicked in another $1000.

    But business didn't go smoothly as they expected. DeLuca says, “After six months, we were doing poorly, but we didn't know how badly, because we didn't have any financial controls.” All he and Buck knew was that their sales were lower than their costs.

    DeLuca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They'd meet Monday evenings and brainstorm ideas for keeping the business running. “We convinced ourselves to open a second store. We figured we could tell the public, 'We are so successful, we are opening a second store.' ” And they did—in the spring of 1966. Still, it was a lot of learning by trial and error.

    But the partners' learn-as-you-go approach turned out to be their greatest strength. Every Friday, DeLuca would drive around and hand-deliver the checks to pay their suppliers. “It probably took me two and a half hours and it wasn't necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out,” DeLuca says.

    And having a goal was also important. “There are so many problems that can get you down. You just have to keep working toward your goal,” DeLuca adds.

    DeLuca ended up founding Subway Sandwich, the multimillion-dollar restaurant chain.

    Many young people these days adore the advertised magazine body and become too focused on attaining this image instead of worrying more about what lasts and even grows over time. But could you imagine being considered beautiful for years, and suddenly being ugly after moving to another continent? It is a sad reality that people don't realize how vacillating the idea of beauty can be from one country to another.

    Think of the most typical American girl you know. Is she blonde-haired with white skin and light blue eyes, and does she love shopping or sports? Now place this girl in the heart of Africa, where beauty is placed on what you can control. The Maasai tribe in Kenya focuses on how clean people are, and how stylish their piercings (穿孔) are. This tribe's culture is to be a brave fighter, so they will cut their skin with patterns in it to show that they are strong. If you don't look fierce, you are not beautiful.

    Other countries like North Korea and South Korea have their own unique views on beauty. In an interview, a woman who has lived in both North Korea and South Korea claims that beauty in North Korea is based more on your ability to be a good woman and wife. She says that women in North Korea are less concerned about fashion and beauty in the physical sense. She says they did have a time when big eyes were a big deal and everyone wanted to get double eyelid surgery. This is something extreme and could perhaps be influenced by Western culture. But don't you think the idea of getting surgery done to look more attractive is crazy?

    It was one of those days when there was way too much to do. I had fallen behind in most of my household chores.

    After breakfast, I sat down at the computer to write an article. My youngest daughter, Julia, walked toward me. "But, Mommy, I thought we were going to do something fun today," she said. "Since it's our day off from school." "I know it's your day off, but it's not Mommy's day off," I explained.

    "Can you play a game with me?" she begged. "Like Candy Land? Or beauty shop?" I sighed. I really didn't have time to play. I desperately needed to get some work done. But then I had an idea. "Can we play beauty shop while I work?" So I got my article done, and my toenails(脚趾甲) painted at the same time. My oldest, Austin, volunteered to fix lunch so I could keep working. Shortly after lunch, we went to the grocery store and I got what I needed. Back at home, the kids decided to play "grocery store". For the remainder of the afternoon, I cleaned house, folded laundry, and started dinner. The kids continued with their game until my husband, Eric, walked through the door.

    He saw me and smiled. "So how was the kids' big day off today?" I began to explain that we hadn't done anything special. But my two middle kids, Jordan and Lea interrupted me. They told their dad, "We had such a special day today, Dad! It was a blast!" I looked at my children's faces. They were lit up with excitement.

    I nodded, realizing how right he was. Happiness is far more about our attitude than our circumstances. I hugged my kids and thanked them for reminding me to look for happiness in the little things. Julia smiled and said, "And the little things that make you the happiest are us, right, Mommy?" Wow, my kids sure are smart.

    Body language is the quietest, secretest and mostpowerful language of all! It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying...

    Arms. How you hold your arms shows how open and receptive you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy!

    Head. When you want to appear confident, keep your head level. If you are a monitor in class, you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little.

    Legs. Your legs tend to move around a lot more than normal when you are nervous or telling lies. If you are at interviews, try to keep them still!

    Posture (姿势). A good posture makes you feel better about yourself. If you are feeling down, you normally don't kit straight, with your shoulders inwards. This makes breathing more difficult, which can make you feel nervous or uncomfortable.

    Mouth. When you are thinking, you often purse your lips. You might also use this position to hold back an angry comment you don't wish to show. However, it will probably still be noticed, and people will know you're not pleased.

    Face. When you lie, you might put on a false face. But that expression would crack briefly, allowing displays of true emotions such as happiness, sadness, disgust(厌恶)and fear to come through.

    The world is a truly strange place waiting to be explored. In addition to offering a lot of extraordinary locations and people, it also offers interesting festivals celebrated by people in various parts of the world. Here is a list of the oddest festivals that can be found around the world.

    Cheese Rolling Festival: A festival that is surely going to leave you with a sore neck if not a broken one! Celebrated in England, the Cheese Rolling Festival is something that you would rather watch than take part in.

    Okay! Here's how it goes. Officials set a big cheese wheel to roll down a steep hill and participants run after it. The first one to catch it wins the competition and the cheese. Simple? Well, try it out and you will know!

    The Monkey Buffet: Now here's a country that actually feeds monkeys to their hearts' content instead of chasing them away. Celebrated in Thailand, the Monkey Buffet is an annual event that brings together a lot of locals who offer fruit and vegetables to over 600 monkeys. It's a great feast as the monkeys dig into almost 3, 000 kilograms of fruit and vegetables. The people of Thailand believe this is a way to honor the Monkey King called Hanuman.

    La Tomatina: Here's your golden chance to get even with your friends who sprayed(喷洒)paint on you on your birthday. Celebrated in Spain, the month of August has nearly 250 pounds of tomatoes go down the drain(被浪费掉)in what is perhaps the largest tomato fight in the world. The event is conducted in the town of Bunyol and attracts nearly 30, 000 tourists around the world in addition to locals. Truckloads of tomatoes arrive and you are ready to go. The entire area is covered with slush and tomatoes within minutes. It's a good time to have fun with friends and family.
