Sure, it's good to get along with your teacher because it makes the time you spend in the classroom more pleasant. And yes, it's good to get along with your teacher because, in general, it's smart to learn how to relate to the different types of people you'll meet throughout your life. But really, there's one super-important reason why you should get along with your teacher. Kids who get along with their teachers not only learn more, but they're more comfortable asking question and getting extra help. This makes it easier to understand new materials and do yours best on tests.

    When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school issues.

    As a kid in elementary or middle school, you're at a wonderful stage in your life. You're like a sponge (海绵), able to suck up lots of new and exciting information. On top of that, you're able to think about all this information in new ways. Your teacher knows that, and in most cases, is thrilled to be the person who's giving you all that material and helping you put it together. Remember, teachers are people, too, and they feel great if you're open to what they're teaching you. That's why they wanted to be teachers in the first place to teach!

    Some kids may be able to learn in any setting, whether they like the teacher or not. But most kids are sensitive to the way they get along with the teacher, and if things aren't going well, they won't learn as well and won't enjoy being in class.

    It was Saturday morning. I heard loud noises of moving furniture in the next room. I could almost feel the excitement of John who was soon going to get a room of his own. I remember my own feelings when I was 13. I knew how much he longed for his right to privacy (私人空间) when he was sharing a room with his younger brother, Robot. He said, “Mum, Can I please have a room of my own? I could use Jeff's. He won't mind.”

    It was true that Jeff had graduated from college and flown from the nest. But would he mind? The room was the place where I told him a thousand stories and we had a thousand talks. As close as we were, though, the time came when Jeff needed a door between us. His life was spreading into areas that had less to do with family. I no longer could-or should-know everything about him.

It turned out that getting Jeff's permission was easy. He said, “Of course, Mum, it would be selfish of me to hold on to it.” Then his voice softened, “Mum, I won't be living at home again—you know that.” Behind his glasses, his eyes were lit with all the love. There were no doors closed here—they had all opened up again.

    As John and I were cleaning the room, I fixed my eyes on Jeff's things around me and could almost touch the little boy who I knew was gone forever. I looked at the room and, in my heart, I let it go. To hold on would be, as Jeff said, selfish. Now it was time for John, shouldering through the door, his eyes bright with promise of independence, to disappear behind the door. It was time for letting go to happen again.

    Parents complain that children outgrow their clothes so fast that it costs a fortune（￡12, 000 on average per year）, going through seven different sizes in the space of their first two years. There could now be a solution：a new high－tech fabric（织物）that expands as the wearer grows.

    Ryan Yasin, who is studying for a master's degree at the London Royal College of Art, came up with the idea after purchasing clothes for his newborn nephew, only to find the baby had outgrown them by the time they arrived. In addition to the expense Yasin was also concerned about the environmental influence. The process of making and distributing just l kilogram, or 2. 2 pounds, of new fabric results in an average of 23 kg, or 50 pounds of greenhouse gases. To make matters worse, the “fast fashion” trend worldwide has caused garment production to double since 2000, with more than half of the clothing ending up in landfills annually!

    To find a solution, Yasin used his previous experience designing satellites to invent a way to fold synthetic（合成的）material such that it stretches in all directions.

    The first design, a pair of tiny pants, not only fit his baby nephew, but also his 2－year-old niece! After spending a lot of time perfecting the process and testing the design, Yasin is now awaiting a patent for his design and seeking investors（投资者）to bring the clothing to market.

    For his new line of Petit Pli, the designer plans to produce outerwear that is both waterproof（防水的）and windproof. The clothing will be machine washable and fold small enough to fit in a jacket or pant pocket. Yasin plans to establish a take－back system so that worn－out Petit Pli clothing can be recycled into new fabric.

    The designer does not expect parents to dress their children only in his expandable clothing, particularly since the current designs use synthetic materials. But he plans to soon produce the wear in “a wider variety of garments” and hopes that Petit Pli will be able to have an “influence on over-consumption. ”We surely hope he succeeds!

    Are you a morning person? You might not like the findings in this new research.

    From a lack of air and drinking water to solar radiation, theoretical Mars pioneers face any number of potential obstacles to settling on the red planet. Now, scientists have found something else to add to the list: seriously messed-up biological clocks.

    One day on Mars - which scientists refer to as the solar day, or “sol”- is 37 minutes longer than a day on Earth. A team of European scientists recently demonstrated why that could be a problem.

    Circadian rhythms are the body's natural cycles of rest and waking, which tend to follow roughly 24-hour light-dark cycles. These natural rhythms - which play a role in biological functions including brain wave activity and hormone production - can be interrupted by things like jet lag（时差）and night shift work.

    For the study, the researchers compared mice with healthy, 24-hour circadian clocks to mice with a genetic change that caused them to have shorter, 20-hour circadian clocks. The mice with healthy biological clocks were more likely to survive and reproduce, while the mice with shorter biological clocks were more likely to die off.

    What does this all have to do with space travel? Since the Martian sol is longer than a day on Earth, people with shorter circadian clocks could suffer from health problems as they try to adapt to the rotational speed of the red planet.

    Unfortunately, the body is unlikely to adapt to the new conditions or “learn” to develop a longer clock. As Loudon explained,“ Learning is not a likely option.”

    In other words: Sorry, super-early risers - NASA might not want you for the next Mars mission.

    Addyson Moffitt is an 8-year-old from Kansas City, Missouri. Maurine Ghelagat is a 9-year-old from a village in Kenya called Bartabwa. It might not seem as if the girls have much in common, but when they met at a dinner two years ago, in Kansas City, they immediately hit it off.

    "We had this one little red ball to play with," Addyson told TIME for Kids. "We didn't have any electronics or phones, no iPads or TV. It was just us playing." Addyson and Maurine still keep in touch now.

    The dinner was hosted by the nonprofit group World Vision International, which builds wells, pipelines, and rain catchers in communities where people find it hard to get clean water. Addyson, was at the dinner because her family supports World Vision. Maurine was there because her village had been without clean water. World Vision fixed that by building a water station there.

    "People helped Maurine so she could have clean water, and kids are dying because they don't have it," Addyson says. "I want to help."

    Races are one way World Vision raises money to pay for its water projects. Runners run a race, often a 26-mile marathon or 13-mile half marathon. They ask people to support them by donating(捐赠) to World Vision.

    Addyson decided to run the 2017 Kansas City Half Marathon for World Vision. At age 7, she was one of the youngest-ever runners in the race, and had to get special permission to take part.

    Addyson spent four months training with her parents, waking up before 6 a.m. to run. Meanwhile, she started fundraising(募捐)by asking friends to make donations as birthday presents and clearing tables at a restaurant for tips.

    By October 2017, when Addyson ran the race, she'd raised more than $20,000. She's the youngest person in World Vision history to raise more than $10,000. In 2018, she ran again and raised $36.000.

    But Addyson's work is not finished. "My goal is for every kid to have clean water," she says.

Teenagers who spend more than six hours online on school days are more likely to be lonely and skip school,according to an international study.

The study examined the home Internet use,well-being(幸福) and behaviour of 296,000 15-year-olds in 41 countries.More than one in four spent more than four hours per day online outside of school.The study found lower levels of well-being among students who spent more than six hours per day online.They were twice as likely as teenagers spending one and two hours per day online to report that they felt lonely at school.These extreme Internet users were also especially at risk of "behaving in problematic ways at school,such as arriving late or skipping class".

The report said,"Lower levels of engagement(密切关系) with school may be connected to less sense of belonging at school.It is also possible that skipping class and arriving late for school are the consequence of lack of sleep among extreme Internet users."It adds,"Parents,schools and health professionals can work together to watch and plan children's use of new media."

The study also found that countries that invest(投资) heavily in Information and Communication Technology(ICT) in schools have seen no considerable difference in 15-year-olds' achievement in reading,maths or science tests.The study results suggest limited use of computers at school may be better than not using them at all.However,students who use computers very frequently at school do a lot worse in most learning outcomes.The report says,"In the end,technology can strengthen great teaching,but great technology cannot replace poor teaching."
