    Childhood is a happy time, right? Not necessarily. Consider these facts.

Depression(抑郁症) may occur in as many as 1 in 33 children.

    Once a child has an episode of depression, he or she has a 50 percent chance of experiencing another episode in the next 5 years.

    Suicide(自杀) is the 6th leading cause of death for 5-to-15-year-olds.

    If your child experiences 5 or more of these signs or symptoms for at least 2 weeks, he or she may be experiencing depression or mental illness.

    Sometimes, a child who causes problems at school or at home may actually be depressed, according to the American Academy of Child and Adolescent Psychiatry.

    If you think your child may be depressed, it's important to have your child treated. Discuss your child's problems with his or her doctor. The doctor may suggest a referral to a children's psychologist or psychiatrist.

    “The failure to play is now a serious issue and it calls for action for change,” says Sir Ken Robinson, a leading expert in education, creativity and human development. This is the driving force behind Outdoor Classroom Day—a global teacher-led campaign, supported by Dirt is Good, a company producing daily chemical products.

    Outdoor Classroom Day, taking place on 17th May and 1st November this year, will see schools around the world swap the inside for the outside and take learning into the playground and beyond to make playtime a key part of the school day. This might involve using natural objects like stones to do sums, or going on an insect hunt to encourage curiosity. By now, Outdoor Classroom Day has grown from a grassroots movement to a global campaign that is expected to benefit five million children and over 40,000 schools from all around the world in 2018.

    This is helping to change the trend that sees many schools selling up or building on their playgrounds and cutting back on playtime to make more room for academic studies, while at home children's lives are increasingly filled with organized activities intended to help them learn. Today globally 61% of parents surveyed in the Dirt is Good Qualitative Study said that children don't know how to play without using technology.

    Outdoor Classroom Day is making playing time happen, with 22% of participating schools having increased their playtime since joining the campaign. 93% of teachers surveyed saw improvements in children's creativity after playing outside, and 97% believe that time outdoors is necessary for children to reach their full potential.

    Scientific studies show that real play—the active, physical, self-directed play—is essential for children to develop key life skills that are not taught elsewhere. Few would question the value of developing creativity, leadership, resourcefulness, and curiosity.

    I think it was October, 1982. A friend had business dealings in the city of Reno, Nevada, and I was asked to accompany her on an overnight trip. While she conducted her business, I was aimlessly wandering down

    Virginia Street，heading into a most gloriously beautiful sunset. I had a strong wish to speak to someone on the street to share that beauty, but I couldn't make eye contact with anyone. Quickly I went into a department store and asked the lady behind the counter if she could come outside for just a minute. She looked at me as

though I were from some other planet and said, “Well…” Surprisingly, she followed me out.

    When she got outside I said to her, “Just look at that sunset! Nobody out here was looking at it and I just had to share it with someone.”

    For a few seconds we just looked. Then I said, “God's in his heaven and all's right with the world.”

    I thanked her for coming out to see it and sharing the beauty.

    Four years later my situation had changed a lot. I had come to the end of a twenty-year marriage. I was alone and on my own for the first time in my life. One day, while my clothes were going around, I picked up aUnity Magazine and read an article about a woman who had been in similar situation. She had come to the end of a marriage, moved to a strange community, and the only job she could find was one she disliked: cosmetic sales in a department store. We had a lot in common.

    Then something happened to her that changed everything. She said a woman came into her department store and asked her to step outside to look at a sunset. The stranger had said, “God's in his heaven and all's right with the world.”, and she had realized the truth in that sentence and that she simply had not been seeing it. From that moment on, she turned her life around.  

Surviving Hurricane Sandy(飓风桑迪)

    Natalie Doan, 14, has always felt lucky to live in Rockaway, New York. Living just a few blocks from the beach, Natalie can see the ocean and hear the wave from her house. “It's the ocean that makes Rockaway so special, ” she says.

    On October 29, 2012, that ocean turned fierce. That night, Hurricane Sandy attacked the East Coast, and Rockaway was hit especially hard. Fortunately, Natalie's family escaped to Brooklyn shortly before the city's bridge closed.

    When they returned to Rockaway the next day, they found their neighborhood in ruins. Many of Natalie's friends had lost their homes and were living far away. All around her, people were suffering, especially the elderly. Natalie's school was so damaged that she had to temporarily(临时地，暂时地) attend a school in Brooklyn.

    In the following few days, the men and women helping Rockaway recover inspired Natalie. Volunteers came with carloads of donated clothing and toys. Neighbors devoted their spare time to helping others rebuild. Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless high-rise buildings.

    “My mom tells me that I can't control what happens to me,” Natalie says. “but I can always choose how I deal with it. ”

    Natalie's choice was to help.

    She created a website page matching survivors in need with donors who wanted to help. Natalie posted introduction about a boy named Patrick, who lost his baseball card collecting when his house burned down. Within days, Patrick's collection was replaced.

    In the coming months, her website page helped lots of kids: Christopher, who received a new basketball; Charlie, who got a new keyboard. Natalie also worked with other organizations to bring much-need supplies to Rockaway. Her efforts made her a famous person. Last April, she was invited to the White House and honored as a Hurricane Sandy Champion of Change.

    Today, the scars(创痕)of destruction are still seen in Rockaway, but hope is in the air. The streets are clear, and many homes have been rebuilt. “I can't imagine living anywhere but Rockaway, ” Natalie declares. “My neighborhood will be back, even stronger than before. ”

A 293-million-mile journey of the NASA Perseverance rover (探测器) to Mars: ended successfully on February 18, 2021, with a picture-perfect landing inside the Jezero Crater. The car-sized, six-wheeled rover, nicknamed Percy is the US space agency's biggest and most advanced explorer to date. Its primary mission is to search for signs of ancient microbial (微生物的) life on Mars.

Landing on Mars is extremely tricky. The Red Planet's gravitational pull causes approaching spacecraft to go faster to high speeds, while its thin atmosphere-just 1 percent that of Earth's-does little to help slow it down as it approaches the surface.

The scientists had to reduce Percy's 12,000 mph speed to a safe landing speed of less than five mph-in just six and a half minutes. The target entry angle also had to be a precise 12 degrees-any steeper, and the spacecraft would burn up; any flatter, and it would get lost in space. It is no wonder that the final approach is often referred to as the "seven minutes of terror. "

Upon attaining a manageable speed, Percy briefly flew over the Martian surface to seek out the perfect landing spot. Its complex map-reading system rapidly scanned the area and matched it with maps in its database to find the best location.

The NASA scientists will spend the next two months testing Percy's scientific instruments. Once ready, the rover will begin to carry out its mission.

"Perseverance is the smartest robot ever made, but confirming that microbial life once existed carries an unusually large burden of proof," said Lori Glaze, director of NASA's Planetary Science Division. "While we'll learn a lot with the great instruments we have aboard the rover, it may very well require the far more well-equipped laboratories and delicate instruments back here on Earth to tell us whether our samples (样本) carry evidence that Mars once harbored life.
