Do other countries' students also have so much homework? What do they usually do in their free time? You may feel curious about them.

On April 8, a report came out on the lives of high school students in China, Japan, South Korea and the US. It surveyed around 6, 200 students from the four countries last year. You will find the answers to many of your questions in this report.

Who studies hardest?

Chinese students spend the most time studying. Nearly half of Chinese students spend more than two hours on their homework every day. That's much more than the students of the US(26. 4%), Japan(8. 2%)and South Korea (5. 2%).

Who sleeps most often in class?

Japanese students fall asleep in class most often. About 45% of them said they soon doze off in class. In South Korea, it's 32%; in the US, 21%; and 5% in China.

South Korean students don't like taking notes. About 70% said they write down what the teacher says in class, many fewer than in Japan (93%), China (90%) and the US (89%).

Who is the most distracted(走神)?

American students are the most active in class, but also the most distracted:64. 2% said they chat with friends in class; 46. 9% said they eat snacks in class; and 38. 9% said they send e­mails or read unrelated books in class.

    On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk, Strayer explained that all this time spent with technology is making our brains tired.

    Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains, is important for critical thinking, problem-solving and decision-making.

    So it is important to give the brain a rest. And being in nature, Strayer claims, helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore, swim, sleep, eat and play. Camping may be just what a tired brain needs.

    Take Carl for example. He lives in West Virginia and enjoys camping. He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children. She calls it a "regenerative" experience.

    At the University of Utah, David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However, he found it is the long-term contact with nature that does the most good. He and his research team found spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

    Michelle Kwan was born on July 7, 1980, in Torrance, California. The daughter of Hong Kong immigrants (移民), Kwan watched her older brother play ice hockey as a kid. She began skating when she was five, and entered and won her first figure skating competition at seven. She won the world title in the 1994 World Championships at the age of 13, and earned a spot as an alternate (候补者) for the 1994 Olympic Games. Kwan went on to capture the world title in 1996, 1998, 2000, 2001 and 2003.

    At the Nagano Winter Olympics in 1998, Kwan was believed to win gold, but ended up with a disappointing silver medal when fellow US skater Tara Lipinski surprisingly took first place. Shortly before the Salt Lake City Winter Olympics in 2002, Kwan, who was then the reigning world champ, surprisingly fired both her choreographer (编舞者), Lori Nichol, and longtime coach, Frank Carroll. Once again, she failed to get the gold medal when she finished third behind Irina Slutskaya of Russia and US skater Sarah Hughes, who took first.

    As a student at the University of California at Los Angeles, Kwan has continued to compete since her defeat (战败) in Salt Lake City. In February 2006, she was unable to take part in the Olympic Games in Torino, Italy because of a serious injury. Though Michelle Kwan did not compete during the 2006-2007 figure skating season, she has turned down an offer to work for NBC Sports and says she is not retiring.

    An online supermarket company—Ocado in the UK, has recently displayed a robotic hand that can pick fruits and vegetables!

    When an embryo (胚胎) is in the womb, the very first sense it develops is touch. The sense of touch is also the one that lasts the longest—as we get older and our vision and hearing begins to weaken, touch still remains. Humans use their touch to protect themselves, to create emotional relationships with other people, and to experience pleasure. Can you imagine life without it?

    The sense of touch comes from a network of nerve endings and special touch receptors on the surface of the skin. While there are different kinds of touch receptors (感受器), they help us judge pressure, texture and vibrations (震动). They are located in our fingertips, palms, soles of our feet, face, lips and tongue.

    When we touch something, the mechano-receptors perceive the touch and through a network of nerves, send signals to the brain. This informs the brain about the location of the touch, the amount of force used, and the speed at which it was used.

    Several different techniques have been tried in the past to create such a robotic hand—using three fingers. But this latest design by SoMa copies the human hand. The gripper (夹具) is made up of flexible materials which grasp onto the thing based on its size and shape. Then air pressure is used to control the movement of the robotic fingers to pick objects safely and without causing damage.

    The next step would be for the robot to judge how ripe the fruits and vegetables are, and apply pressure accordingly. Members of the research team are currently working on adding computerized vision to the robots, so that they can see what they are gripping.

    Does all this mean robots can replace people? According to Ocado, it helps improve productivity by removing some of the repetitive tasks done by humans.
