I grew up in New York my whole life. I studied in a perfect college that happened only to be an hour away from home. Then, about three weeks before the spring term was over, my parents told me we were moving to Arizona that summer. They asked me if I was going to transfer (转学) to another college. I said no. I was not going to change everything in my life at one time and I loved my college and all the amazing things I was doing there. It was my second home; I would not leave everything I knew at the same time since that was asking for trouble.

    I never imagined it would be this hard but, at the same time, the best thing that could have happened to me.

    When out in Arizona, life was hard. I didn't know anyone other than my family and friends. I couldn't bear the extreme heat. But it has helped me so much. I have started working on my writing. I also have time to work out in the gym. It has helped me realize that no matter where you are or who you know you can always find something that you enjoy.

    When back at school in New York, it was hard as well. Living close to home was my security blanket. If something was wrong I could get in my car and drive home and see my family. After my family moved to another city, I lacked security and was always controlled by anxiety. However, it helped me learn independence and forced me to be brave.

    I' m so thankful that I didn't transfer to a different school, which has given me the opportunity to go back and see best friends in my hometown. A year ago, I officially left my hometown for good. It has helped me grow and I am so thankful that I have had this experience. Now, when I graduate from college, I can go anywhere I want. I am no longer afraid to go out on my own into the world. The world is full of opportunities and pleasure and I can't wait to see where I will be next.

    A primary school in Jinhua, Zhejiang Province has announced it no longer requires parents to sign their children's homework, which was aimed at getting parents to supervise(监督) their children after school. China Youth Daily comments: Putting an end to the requirement that parents sign off on the homework of their children eases the burden on many parents, as otherwise they would have to do primary school homework after a hard day's work. But there are worries that if parents stop having to sign off on their children's homework, the children will not get good grades.

    However, the most effective way for children to study is to develop their willingness to learn and do their own studies. When doing homework, students practice and hopefully apply what they have learned. It is true that teachers are supposed to check students' homework and identify their mistakes. But some parents correct their children's mistakes by themselves when signing off on it.

    It is the duty of students to do their homework, be responsible for their studies and correct their mistakes. Parents' supervising their homework, checking their answers and dealing with the harder problems will only make children less aware of their mistakes and encourage them to wait for their parents' help when they face any problems.

    Children have to manage their own learning and develop the ability to study by themselves, as competence will not be achieved if a student simply repeats strict tasks in which he is assisted in school by teachers and at home by parents.

    A delayed satisfaction experiment conducted by Walter Mischel in the 1960s proved that children with better self-discipline(自律) performed better in their studies and interpersonal relationships.

    There is little doubt that parents' supervision can make children's homework better. But it does not give children the chance to practice their ability to solve problems independently.

    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.

    Reading books and looking at pictures is great, but nothing facilitates (促进) learning like travel, especially for teenagers. Not only do they get to see a world beyond their neighborhood, they also get to experience it, feel it, taste it, hear it and better understand the world around them.

    After nearly four decades in the classroom and traveling the world, Phyllis Duvall Bailey knew this perhaps better than anyone else.

    Becoming involved in the work in AKA Sorority Inc in US, she worked to educate children about the United Nations. There was no doubt in Bailey's mind that the lessons would mean so much more if the students could see things for themselves.

    Starting in 2015, Bailey, 82, set out to take her students to the UN Headquarters in New York City to give them a "Window Seat to the World", and thus transformed them into global citizens.

    Indeed, it is a great opportunity to give students national and international exposure. Since Bailey saw the students as future leaders, she was desperate to expose them to the UN, its mission, its agendas (议程) and its supporting organizations.

    She decided to give $10, 000 of her own money to pay for the late June trip, enough to take 10 students aged 14-17 on a four-night stay in New York. There, they had guided tours of the UN Headquarters and the New York City Harbor (海港).

    It was Quenyaun Payne's first trip to the city and Taylor Sappington's second. Payne, 17, is a senior at Mceachem High School in the state of Georgia, US. Sappington, 15, is a junior at Therrell High School in Atlanta, Georgia, US. Both said their visit to the UN was inspiring.

    "I like not only how countries are working together but they're focused on common goals like global warming and keeping peace," Sappington said.

Payne commented, "The trip was amazing. I'm so thankful Mrs. Bailey made it possible."

    Actually, there are a lot of people grateful for the retired teacher's effort. The United Nations Association of Atlanta recently gave Bailey its Humanitarian Award, and the United Nations Association of the US-awarded her with the National Education Award.

    But Bailey wasn't looking for recognition or even gratitude. Over those four days in New York, she'd already felt it and seen it in the eyes of those 10 teenagers, Payne and Sappington included, who made the trip.

    "It has been a real joy to get to see and watch their reaction to new experiences," she said.

An Edinburgh inventor has created a fully biodegradable bottle that is made from paper and a secret combination of plant materials, and it could help save the planet's oceans from plastic pollution and can also be eaten by sea creatures.

The Edinburgh-based Durham University chemistry graduate James Longcroft started a non-profit bottled water company two years ago. He wanted to put all his profits into a charity that provided clean drinking water to countries in Africa.

However, after concerns about the environmental impact of plastic bottles, Mr. Longcroft decided the Edinburgh and London-based company, Choose Water, should go plastic-free. So he came up with a new type of water bottle—a waterproof paper bottle.

"The outside is made from recycled paper, but the inside has to be waterproof, and provides strength so the bottle would keep its structure, and keep the water fresh," Mr. Longcroft said.

When the bottle is thrown in the ocean the degrading process begins within hours leaving the bottle totally degraded (分解)within weeks. The steel cap breaks down within a year.

Mr. Longcroft now believes these novel bottles could revolutionise the industry and says the cost of producing the bottle is around 5 pence more than one made from single-use plastic.

"The main difficulty we face is breaking into a saturated (饱和的)market and competing with an old industry," he said. "Changing an industry will be a big uphill battle, but with the support from the public, we will change the way we look at bottled water."

Researchers warn that eight million tonnes of plastics currently find their way into the ocean every year which will stay in the environment for centuries.

"We really want to get our bottles on shelves and into people's hands as soon as possible—if we can stop even one plastic bottle ending up in the environment it will be worth it," said Mr Longcroft.

Throughout our lives,we have been told to take care of our physical health.But what is often ignored is mental health.That's why World Mental Health Day was created.{#blank#}1{#/blank#}.

When is World Mental Health Day?

World Mental Health Day is on October 10th.Though there is one specific date for it,it is often times celebrated and observed over the course of a week.{#blank#}2{#/blank#}, it allows more people to know about the importance of mental health and it educates the public about the "why", "how" and "what" of mental health.

What is the history of World Mental Health Day?

{#blank#}3{#/blank#}.When it first started,the day had no theme,but instead was an excuse for medical workers to educate the public on what was not always openly discussed — what mental health is and the issues that surround it.Mental health affects everything from our emotional state to our physical state,and everything in between.In the first few years,organizers usually hosted a global live broadcast,leading to live telephone participation from all over the world.
