No rows of desks in this classroom, and no teacher lecturing at the front. In fact, that's something Barrie teacher Liz Collett rarely does. Instead, she's on the move, talking to students about their work, from the small group sitting on the floor playing games to others nearby figuring out a math problem.

    The children in this class do not take a spelling test all year－in fact, the school avoids all pencil-and-paper tests－nor do they get assigned homework. Instead, their teacher gives them immediate feedback（反馈）on their work throughout the day.

    Welcome to the school of the 21st century, a place where teachers and students cooperate all the time. Such advanced classrooms are trying things, which some might consider as coddling kids－letting students give a voice-recorded essay instead of a written one or even allowing teens to design their own courses.

    Though some people blame（谴责）schools for dumbing things down（降低教育标准）, others will say such changes are actually based on the newest research on how to attract today's youth and increase not only their interests, but also their achievements. Many of today's school are not holding kid's interests. And if they Ye not interested, they're not learning－and isn't that the point?

“Students today say they want their education to be useful and valuable, and don't want it to be simply repeating the facts. That's the kind of learning that be happening for many kids,” says Penny Milton, a researcher. “What we could argue is that to become good learners, they need to become thinkers.”

    Jan Olson, anther researcher, says schools have been operating the same way since the Industrial Revolution. But the digital age is bringing an education revolution. While using technology is a part of it, what's important for students is being able to use information and understand it, not just remembering it.

    Today's learner needs fewer traditional tests and more “effective” feedback, ongoing discussion with a teacher, which studies have found is the number one factor in improving achievement.

    We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.

    A brain can also simply be a smart person. If a person is called brainy, he is smart and intelligent. If a family has many children but one of them is super smart, you could say, “He's the brains in the family.” And if you are the brains behind something, you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.

    Brain trust is a group of experts who give advice. Word experts say the phrase “brain trust” became popular when Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues(问题)facing the U.S. These professors were called his “brain trust”.

    These ways we use the word “brain” all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word “drain”. As a verb, to drain means to remove something by letting it flew away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.

    However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.

    If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make some accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.

    I was reading these interesting stories behind a group of great logos in the world. Personally Nike is my favorite one—it's so simple. And I like the stories behind them, which made me forget all other things. McDonald's, Apple, Mercedes Benz and Adidas own great logos as well, and they are among my favorites.

    Nike

    In the Greek myth, Nike is the goddess of victory and the source of inspiration for soldiers. This logo represents the wing in the famous statue of the Greek goddess. Nike's logo was designed by Carolyn Davidson in 1971 for $35, and was registered as a trademark in 1995.

    McDonald's

    The logo was designed in 1962 by Jim Schindler to resemble the arch-shaped(拱形的) signs on the side of the company's then walk-up hamburger stand. Later on, the two golden arches were combined together to form the M. The McDonald's name was added to the logo in 1968.

    Apple

    There are different stories behind Apple's logo. The first logo was a reference to the religious story of Adam and Eve, in which the apple represented the fruit of the Tree of Knowledge. One year later, the second logo was designed in 1977 by Steve Jobs and Ronald Wayne, and it described Sir Isaac Newton sitting under an apple tree. This logo didn't stay long. One year later it was replaced almost immediately by graphic designer Rob Janoff's "rainbow apple", a rainbow-colored silhouette(轮廓) of an apple with a bite taken out of it. And then the rainbow-colored apple was replaced by the one-colored logo in 1998. It has not been changed so far.

    Mercedes Benz

    The Mercedes Benz logo, which was originally created by Gottlieb Daimler in 1909, consists of a simple description of a three-pointed star that represents its rule of the land, the sea and the air. The company was founded by Gottlieb Daimler and Wilhelm Maybach. Mercedes is the name of Maybach's elder daughter, while Benz came as a result of a combination with Benz, Cie and DMG in 1926.

    Adidas

    The Adidas logo, which was created by the founder of the company Adi Dassler, represents mountains, pointing towards the challenges that are seen ahead and goals that can be achieved. The logo was used for the first time in 1967.

    Learning any language is hard, but learning English can be especially challenging. Why? Because native speakers use the language in ways that textbooks could never describe. In particular, words that British people use cause many language students to scratch(JT) their heads.

    Here's an example: You happen to hear a Briton calling someone a “wazzock”. But what exactly is a wazzock? This word, in fact, means a foolish person, although there's nothing about it that would help you guess that. There are many strange terms like this in British English - the Oxford English Dictionary would be much smaller without these strange usages filling its pages.

    How can these odd words be explained? Part of the answer is the British sense of humor. Britons don't like to take things too seriously, and this is evident through many British words and phrases. For example, to spend a penny means to use the bathroom. It refers to the days when people had to pay a penny to use a public toilet.

    In an interview for the BBC's website, British linguist David Crystal suggested there may be historical reasons for the sheer number of odd words and phrases in British English. He thinks that they began in the late 16th and. early 17th centuries. This was a great age for the theatre, when Shakespeare and other writers worked hard to keep up with the demand for new plays. The theatre's popularity also created an incentive (刺激) to invent new words.

    With this in mind, perhaps Shakespeare and his peers are to blame for unusual British words such as “codswallop” and “balderdash”—which both, ironically, mean nonsense.

    While these strange words may be confusing to non-native speakers, they certainly make studying English a lot more interesting.

    Corporate culture is the values and beliefs a company develops over time. The role of corporate culture is to improve a company's mission and strategies, with long-term hopes of improvements in a company's profit. Mostly corporate culture comes from a company's top management.

    One role of corporate culture is to influence employee behavior, honesty, and compliance（服从）. A company does not have to necessarily create a direct influence for these actions. A direct influence may be a set of written regulations or other policies, and while these may be in place, the corporate culture is usually more of an indirect influence.

    While many companies try to create corporate culture through the use of written policies, its role is harder to define. The human factor has an influence on how corporate culture is expressed. The way uppermanagement acts and reacts to various situations defines how lower-level employees will act, and this aspect may be more important than any written policy.

    A company's corporate culture can also extend beyond the walls of the business. Consumers who believe a company to be honest and forthright（直率）may be more loyal in their buying behavior. Employees in a company's customer service department can also exhibit positive corporate culture to outside individuals. In this case, the culture creates a link between the company's employees and its customers. How customers react may be a direct result from the company's corporate culture.

    Product quality can also be influenced by a company's corporate culture. Companies that focus only on profits may decide to avoid high-quality materials in products, but try to suggest that the products are of higher quality than they really are. This negative culture can then result in lower brand loyalty with consumers.

    It is rightly said that one can share any secret with a true friend. He may know your deepest fears and weaknesses and yet will never take advantage of you. However, keeping a friend's secrets to yourself and not telling the world is what makes the bond(关系)grow strong and last forever. You need to develop trust and mutual(互相的)understanding before you start sharing secrets with each other. With friends, secret talks never seem to end and it can get really amusing to know what has been going on in your friend's mind.

    There is a certain time in life especially from the teenage years when one starts having a personal periphery(界限) in life and parents are excluded (排斥)from it. It is because there are certain things that they can't understand and we can't discuss with them. That is when friends become the best secret sharers. They are the ones to whom one reveals one's feelings and best kept secrets.

    It is a general belief that only girls share secrets. But boys have their own secrets that they discuss with only closest friends. The secret talks can range(变化) from relationships, talks about fights with parents, secret activities and anything that is not supposed to be known to others! If you think secrets are limited to only teenagers, get your facts right! Secrets can be shared at any age and there is no hard and fast rule that secrets are shared only among youngsters.

    Sharing secrets with a friend is not just fun, but it also helps to develop a lasting trust in one another. Sometimes, sharing secrets will tell you more about the person. You will come to know whether your friend is reliable and trustworthy and whether it is worth sharing your secrets with them. You can call it a test of friendship.
