Which comes first, happiness or money? Are richer people happier? And if so, how do people get much richer? A recent study could tell you the answer.

    The study looked into thousands of teenagers and found that those who felt better about life as young adults tended to have higher incomes by the time they turned 29.Those who were happiest earned an average of $8,000 more than those who were the most depressed.

    The researchers, from University College London and the University of Warwick, say that very gloomy teens, no matter how tall or smart they were, earned 10% less than their peers, while the happier ones earned up to 30% more.

    Happier teenagers have an easier time getting through school, college and a job interview, chiefly because they always feel better about life. It may also be true that happier people find it easier to make friends, who are often the key to homework help or networking.

    A report in June suggested that professional respect was more important than dollars in terms of workplace happiness. In August scientists announced that they had found the gene for happiness in women, Alas (the same gene doesn't appear to have the same effect on men).And in October researchers in the UK and in the US announced that people who eat seven portions of fruit and vegetables a day report being the happiest.

    The big question is: if it really is true that happier kids end up being wealthier kids , is it necessary for parents to get their kids to do the homework? The fact is that no homework will make kids happy but surely hurt their grades. Studies do show, after all, that more education leads to better-paid jobs, which may give us a deep thought.

    "These findings show that the teenagers' happiness is important to their future success," one of the report's authors writes. "But what is the most important is that we should find a way to help children gain more satisfaction from doing schoolwork."

    LEADING INTERNATIONAL SCHOOLS 2019

    Jerudong International School(JIS) , Brunei

    “Achieving Excellence” is the motto of JIS, Brunei. A developing boarding school of 1,700 students, 40% Bruneian, JIS has made itself a leading school in Asia. With almost 200 highly qualified teachers primarily from the UK, the 120-acre single campus (校园) close to both coast and rainforest offers a unique educational environment. There is a Performing Arts Centre, 27 science laboratories, libraries and classrooms.

    The American International School (AIS), Austria

Founded in 1959, AIS is the oldest English-language school in Austria. School programs focus on academics, but also on the development of students' creative and leadership abilities and emotional intelligence. The school recognizes students' special learning styles, trying to make instruction different and allowing students to reach their full potential in different areas.

    Singapore American School (SAS), Singapore

    Founded in 1956, it is one of only a few good non-profit schools in Singapore. For over six decades, SAS has provided students from preschool to Grade 12 a good American education with an international view. The school supports professional development financially and continually sends teachers across the globe to discover new ideas and best practices from influential educational institutions.

    Santa Clara International School (SCIS), Spain

    In the school, when you walk into a classroom, you'll see hands raised, small groups assembled (集合), and presentations underway. You'll find teachers creating cooperative partnerships with students, encouraging them to discover and connect. You'll observe children working on meaningful hands-on projects that build skills and excite creativity. The teaching philosophy is that learning happens everywhere: in the classrooms, in the city, in a museum, on a farm, or just a walk around the neighborhood.

    Machines equipped with artificial intelligence (AI) have performed better than human beings in a high-level test of reading comprehension. Two natural language processing tools received higher test scores than humans in recent exams.

    One of the tools is a product of the American software maker Microsoft. The other was created by the Chinese online seller Alibaba Group. The company said that a deep-learning model developed by its Institute of Data Science of Technologies was the first to beat a human score in the reading comprehension test.

    The test is called the Stanford Question Answering Dataset. It was developed by researchers at Stanford University in California. It has over 100,000 questions and answers. They are based on information found in over 500 stories from the Wikipedia website. The answers to all the questions come from the reading material.

    The AI-powered machines were tested on whether they could provide exact answers to the questions after processing large amounts of information.

    Alibaba said its deep neural (神经的) network model received an “Exact Match” score of 82.44 on the Stanford test. Microsoft reported that a team at Microsoft Research Asia had a score of 82.65. It said the human score on the same questions and answers was 82.304. Many research organizations also appeared on the list—all with scores below 82.

    Alibaba said it has already used its reading comprehension model in different parts of its business. For example, the company is using machines to answer many incoming telephone calls from customers. The company says in the future, the technology could enable machines to guide visitors through museums or provide advice to medical patients.

    Microsoft noted that, overall, people are still much better than machines at understanding the complexity and nuances (细微差别) of language.

    Katherine Johnson, a brilliant mathematician at NASA (美国宇航局), began working on the space program in the 1950s. Many of NASA's first missions were made possible by her amazing calculations (计算).

    As a child, she loved to count. Her father placed great importance on education and insisted all four of his children go to college, working overtime to pay for it. Johnson said this atmosphere was important to her success. "I was always around people who were learning something. I liked to learn." She said.

    Johnson graduated from high school at 14 and college at 18. In 1953, Johnson started to work for NASA, doing the math that powered engineers' work. Then, because of her outstanding talent, she was moved to work on rockets with an all-male flight research team. As for Johnson, her calculations contributed to many of NASA's most important projects. In 1961, with the help of Johnson's work, Alan Shepherd became the first American to go into space. Johnson also lent her unbelievable talent to the success of the Apollo 13, which had trouble getting back to earth. She worked hard to calculate a safe path back to Earth for the astronauts.

    Johnson retired in 1986, but her huge contribution to the space program has only been reaching the public attention for the past few years. Part of that is because, as she is the first to admit, science is based on collaboration. "I never took any credit because we always worked as a team, it was never just one person," she said in a 2010 interview.

    Earlier this year, NASA named a new data center after her. She was also given a Silver Snoopy award, which recognizes "outstanding performance, contributing to flight safety and mission success."
