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 of 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.

    After the operation, Peter suffered severe pain, but insisted that he didn't need any treatment. One evening, he found Susan, his wife, crying in the kitchen of their apartment in a rare outburst of frustration. “If you won't help yourself, no one else can,” she said.

    Peter started a list “How to Help Myself”, and on it he wrote, “Keep communicating with the doctors, even if they are dark thoughts.” On October 20th, a few days before his 33 birthday, Peter wrote in a Facebook post, “It's been hard to get along with having an incurable Grade 4 brain cancer; it's been hard not to get angry and sad about it; and it's been hard to accept that modern medicine isn't able to fix me.” But at the same time, he wrote, “Every day I wake up not-dead is a gift.”

    Peter and Susan had other lists, detailing the things that they hoped to accomplish in life, which included a trip to Wimbledon; climbing Mt. Snowdon in Wales; and a list of musical wishes—from learning the Bach sonatas (奏鸣曲) and partitas (变奏曲) to performing the first violin part in a concert.

    Peter started working on Bach's six sonatas and partitas, the most difficult parts, which George Enescu, a world-famous violinist, once described as the Himalayas (喜马拉雅山) for violinists. Peter practiced every day, even if he could manage only fifteen minutes between medical treatments. As he mastered each piece, he posted his performances on Facebook. He finished on November 12th, then turned to the even more difficult Paganini caprices (随想曲), which he had often listened to in a recording by Itzhak Perlman. “It's something I always wanted to play when I grew up, like wanting to be a great baseball player,” he said.

    Based on the State Information Center (SIC)'s definition for a sharing economy, payment for knowledge can be regarded as a process of turning knowledge into commercial products or services. To be specific, people can share their knowledge with others via Internet platforms, meanwhile bringing themselves extra income. These platforms, at the same time, earn their profits on that.

    The year 2016 marked the beginning of knowledge payment in China. An investigation jointly conducted by Guokr and Netease's online platforms shows that 70% of users have paid for online learning; while in 2015, the number was only 26%.

In May, 2016, Zhihu, a Chinese question-and-answer website, launched Zhihu Live (payment sharing). Within three days, these new platforms attracted over one million users. In June, Luo Zhenyu, founder of LUOgic Show, launched Li Xiang's Commercial References on iget(得到网)，and within two days over four million users subscribed; in August, Z/"7m's approval & tip function, Snowball O&A, Lenovo's Zhiliao Q&A came online; in September, Huxiu (虎嗅网)began to provide in-depth reports to VIP payment members. Other paid knowledge platforms such as Ximalaya FM, Douban，have also been developing their knowledge payment services.

    People with a wealth of knowledge and experience in specific areas are the most likely to benefit from payment for knowledge. Senior managers in large multinational companies like Google, financial elites with top university backgrounds and well-known psychologists, can all profit from these online platforms. But the opportunities also favor the ordinary: a body-builder, a girl who traveled around the world, or a student that passed a postgraduate entry exam can all set up a live classroom. One hundred minutes of audio sharing cost ¥ 19.9 or $2.9, and thousands of users might pay and join the course, bringing those with specific knowledge remarkable income.

    In the 2017 China's Sharing Economy Development Report provided by the SIC，the turnover in China's knowledge market measures about Y61 billion, or $9 billion，which is a 205% growth compared to last year; the number of payment for knowledge users reached 300 million, accounting for half of all Chinese Internet Users.

    The investigation shows that, males are the majority of the users, accounting for nearly 60%: 25-35 year olds account for 59.3%, which mirrors the majority of Internet users, 63% of the paying users are college graduates, and 53.9% of the paying users have an income of Y3-8k,or $ 441-1176, and most are employees and junior management.

    On March 2, at the meeting held ahead of the yearly session of the CPPCC National Committee(全国政协大会), interpreter(口译员)Yao Mengyao caught the attention of many with her "quick reaction and correct translation," Xinhua noted,

    Yao began her studies in English in primary school where she would listen to English tapes. She ofen spoke to her teacher about English-related topics that were not limited to the ones in her textbooks, "They were always very professional uncommon topics, "said Yao's senior school teacher Shen Yingzi,

    Like Yao, Zhang Lu is a regular interpreter for China's top leaders, including Premier Li Keqing and former Premier Wen Jiabao Her effortless but on-point translations of ancient poems mentioned by former Premier Wen won praise.

    So how do interpreters reach their top positions?

    The reason for their success is largely hard work. Other than when they go out on visits with Chinese leaders, the interpreters follow a very strict schedule. Zhang called this schedule"an unshakable plan". They listen to foreign media such as BBC, VOA or CNN through TV or radio for their training.

    It is reported that a month before the two sessions(两会), the interpreters get notice of the spokesperson they are going to interpret for. They then make full use of this month to prepare themselves. They try to predict the questions that might be asked and consider the sayings the spokesperson might use when they answer the questions.

    In truth, there is no secret to their success: It's all a matter of skill and hard work.
