A brain can also simply be a smartperson,  If a person is called brainy,she is smart and intelligent. If a family has many children but one ofthem is super smart, you could say, "She'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 popularwhen Franklin D. Roosevelt first ran for president in 1932, Several professors gave him advice on social and political issues facingthe U.S.

    These professors were called his "braintrust." These ways we use the word"brain" all make sense. But other ways we use the word are not so easy to understand. Forexample, to understand the next brain expression, you first need to know theword “drain." As a verb to drain means to, remove something by letting it flow away. So abrain 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 agreat 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. Forexample, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.

    If people are brainwashed, it does notmean their brains are nice and clean. To brainwash means to make someone accept new beliefs by using repeated pressure in a forceful or tricky way. Keep inmind that brainwash is never used in a positive way.

    America's businesses are getting older and fatter, while many new businesses are dying in infancy.

    A study last month by the Brookings Institution found that the proportion of older firms has grown steadily over several decades, while the survival rate of new companies has fallen. In addition, young people are starting companies at a sharply lower rate than in the past.

    A new report from the National Association of Manufacturers shows a major cause: The cost of obeying government regulations has risen to more than $2 trillion (12.26 trillion yuan) annually, or 12 percent of the GDP, and this cost falls disproportionately on smaller, newer businesses.

    It's risky, difficult and expensive to start a business, and getting more so. Governments are imposing various new rules on a seemingly daily basis: health insurance, minimum wage increases and, most recently in California, compulsory paid sick days for even hourly employees. These regulations shift huge social welfare costs directly onto often-struggling small businesses, while being proportionally much less costly for larger companies.

    This is partly an unintended issue of resources—established companies can cope with new costs more easily—but it's also deliberate. For instance, big insurance companies got a seat at the table to help write Obamacare, but less politically powerful firms—like medical device manufacturers—got squeezed.

    Mature, successful corporations can employ ex-lawmakers with connections, distribute campaign contributions and even write regulations for themselves. They are also more likely to want to protect steady revenue streams than revolutionize their industry.

    Major companies that have been so ill-managed they would otherwise collapse—airlines, car companies and banks—stagger（蹒跚）on because politicians ride to the rescue with bags of taxpayer money.

    The genius of our unique system of government is the determination to protect and defend the rights of the individual over the rights of the nation. As such, the rise of a well-connected oligarchy（寡头政治）that protects big business at the expense of small business, and the established over the new, is opposite to American ideals.

    Income inequality—which is directly caused by faulty government policy—is being promoted as the reason to impose more of that bad policy. But let's be perfectly clear, we do not have a free market but one where government picks winners and losers through regulations and financial aids.

    Politics is, and always has been, about balancing competing interests seeking to benefit themselves, and that's as it should be, but the force of government should never be used to reduce competition, kill innovation or support and extend artificial monopolies（垄断）by harming the consumer, the taxpayer and the economy. Policy must breed our new and small businesses or see the as-yet undreamed of innovations that could be our bright future die in infancy.

    The science fiction type of entertainment is considered by mot to be fathered by Jules Verne (A Journey to the Center of the Earth and Twenty Thousand Leagues Under the Sea) and H. G. Wells (The Time Machine and The War of the Worlds). Sei-Fi, as it is commonly shortened, is a fictional story in which science and technology have a significant influence on the characters and plot. Many such works are guesswork about what the future holds and how scientific findings and technological advances will shape humankind.

    Writing in the late 1800s, Jules Verne was remarkably successful in his 10 guesses about future technologies of air conditioning, automobiles, the Internet, television, and underwater, air, and space travel. Unbelievably, of all places from which to choose, Jules Verne guessed Tampa, Florida, USA as the launching site of the first project to the Moon, which was only 200 kilometers away from the actual 1969 location at Cape Canaveral, Florida.

    One of the best-known science fiction books is Nineteen Eighty-Four by George Orwell. Published in 1949, it was not meant as a prediction, but as a warning: Orwell was describing what he saw as the outcome of the ideas, trends, and emerging technologies of his time. Many invented terms from this novel have become common in everyday use, such as “big brother” and “doublethink”. Even the author's name has been made into an adjective—Orwellian—and has become a warning descriptor for situations where privacy is lost and the individual has no power and is completely controlled by the government. Nineteen Eighty-Four was translated into sixty-five languages within five years of its publication, setting a record that still stands.

    What helps bring science fiction into being is usually a new discovery or innovation. The author creates an analysis of the potential influence and consequences and then wraps it in a pleasant story. For example, the beginning of space exploration was followed a few years later by the Star Trek television program and movie series. The science fiction author's self-determined role is search the world of future possibilities upon the road which we are traveling.

    Frank Woolworth was born in Rodman, New York, in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be a farmer. So he took a short business course, and went to work as a salesman in a large city.

    Woolworth realized he had a natural skill for showing goods to attract people's interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.

    Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities(大量) directly from the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.

    By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made a lot of money and his name became famous throughout the world. He always ran his business according to strict rules, of which the most important was: “ THE CUSTOMER IS ALWAYS RIGHT.”

Deep Time by Riley Black

Want to know the story of our planet?Riley Black takes us on a journey,in the order of time,through the geological(地质的)events that have shaped our planet.The fascinating high-quality images are supported by easily digestible explanations of key historical moments.It also expands on key concepts in geology,astronomy and biology. Yet,measuring the size of some objects on the photos is difficult due to the lack of a scale bar(比例尺).

My clder brother Steve, in the absence of my father who died when I was six, gave me important lessons in values that helped me grow into an adult.

For instance, Steve taught me to face the results of my behavior. Once when I returned in tears from a Saturday baseball game, it was Steve who took the time to ask me what happened. When I explained that my baseball had scared through Mrs. Holt's basement window, breaking the glass with a crash, Steve encouraged me to confess(认罪) to her. After all, I should have been playing in the park down Fifth Street and not in the path between buildings. Although my knees knocked as I explained to Mrs. Holt, I offered to pay for the window from my pocket money if she would return my ball.

I also learned from Steve that personal property is a sacred(神圣的) thing. After I found a shiny silver pen in my fifth-grade classroom, I wanted to keep it, but Steve explained that it might be important to someone else in spite of the fact that it had little value. He reminded me of how much I'd hate to lose to someone else the small dog my father carved from a piece of cheap wood. I returned the pen to my teacher, Mrs. Davids, and still remembered the smell of her perfume as she patted me on my shoulder.

Yet of all the instructions Steve gave me, his respect for life is the most vivid in my mind. When I was twelve I killed an old brown sparrow in the yard with a BB gun. Excited with my accuracy. I screamed to Steve to come from the house to take a look. I shall never forget the way he stood for a long moment and stared at the bird on the ground. Then in a dead, quiet voice, he asked, "Did it hurt you first, Mark?"I didn't know what to answer. He continued with his eyes firm," The only time you should even think of hurting a living thing is when it hurts you first. And then you think a long. long time." I really felt terrible then, but that moment stands out as the most important lesson my brother taught me.
