    Japanese students work very hard but many are unhappy. They feel heavy pressures from their parents. Most students are always told by their parents to study harder and better so that they can have a wonderful life in the future. Though this may be a good idea for those very bright students, it can have terrible results for many students who are not gifted(有天赋的) enough. Many of them have tried very hard at school but have failed in the exams and have their parents lose hope. Such students felt that they are hated by everyone else they meet and they don't want to go to school any longer. They become dropouts.

    It is surprising that though most Japanese parents are worried about their children, they do not help them in any way. Many parents feel that they are not able to help their children and that it is the teachers' work to help their children. To make matters worse, a lot of parents send their children to those schools opening in the evenings and on weekends — they only help the students to pass the exams and never teach them any real sense of the world.

    Many Japanese schools usually have rules about everything from the students' hair to their clothes and things in their school bags. Child psychologists(心理学家) now think that such strict rules are harmful to the feelings of the students. Almost 40% of the students said that no one had taught them how to get on with others, how to tell right from wrong and how to show love and care for others, even for their parents.

    Some of the world's biggest companies—Apple, Amazon, Facebook—didn't exist 30 years ago. So what firms are we working for in 2050? That's a question put forward by historian Yuval Noah Harari in his new book "21 Lessons for the 21st Century".

    He argues that because technology is changing so fast, it's one of the first times in human history when we don't know what jobs will look like in the coming three decades." So the best bet is to focus on emotional intelligence（EQ）," he said. "Information is the last thing the kids need. They have too much of it."

    In this book, he focuses on the various challenges facing us today. As he writes in the book's introduction: "What are today's greatest challenges? What should we pay attention to? What should we teach our kids?" One area where these questions crop up is artificial intelligence（AI）Harari believes that AI will completely affect the job market for the next generation of workers.

    His first two books—"Sapiens" and "Homo Deus"—became international bestsellers, selling more than 12 million copies worldwide. They were praised by the likes of Mark Zuckerberg, Barack Obama and Bill Gates. Harari's books, about the past and future of humanity, attract a great number of fans. Fellow Israeli, actress Natalie Portman, is a fan. So is American R&B star Janelle Monae.

    As for Bill Gates, he might be Harari's biggest fan. So when the New York Times asked him to review Harari's latest books, he jumped at the opportunity. "All the three books wrestle with some version of the same question: What will give our lives meaning in the decades and centuries ahead?" Gates wrote in his review. "So far, human history has been driven by a desire to live longer, healthier, happier lives. If science is eventually able to give that dream to most people, and large numbers of people no longer need to work, what reason will we have to get up in the morning?"
