A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love(早恋)may bring stress for young people and can lead to depression. The study shows that girls become more depressed than boys, and younger girls are the worst of all.

    The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study，even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won't tell that to their parents.

    Dr Marianm Kaufman，an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build b friendships and a b sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.

    Parents should watch for signs of depression—eating or mood changes—and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity(成熟)gives us a chance to avoid its bad side effects.

    As more and more schools rush to put digital devices（数码设备）in the hands of every student, many parents are becoming increasingly concerned about the quality of their children's education. The promise of increased student academic（学业上的）achievement through the use of technology hasn't produced any significant results in the past 20 years.

    Researchers at the University of California Los Angeles conducted a study in 2014 to determine if the social skills of elementary students were blocked by screen time. Two groups of sixth grade students were compared. One group was sent to an outdoor camp for one week with no screen time, while the control group live life as normal. After one week, the students at camp had made significant improvements over their peers（同龄人）. The good news is that when we limit access to screen time and give children the opportunity to interact face to face, they quickly become better at reading the emotional state of others. The bad news is that we have a generation of children that struggle with this basic emotional intelligence skill.

    Too much screen time has been linked to childhood obesity, sleep disorders, behavior problems, and academic challenges. But is there a difference between schoolwork and entertainment media?

    When students are using technology for academic work they are more likely to be communicating with peers, working cooperatively, and developing other important skills. However, all these are impossible when students watch entertainment media. They just sit and watch!

    Parents have right to be concerned about their children's screen time at school, but they should begin by discussing the use of digital media at home. Some parents are continuously engaged in their own devices, responding to every ring of their phones, receiving and sending messages. How can they expect their children to do better?

    I am astonished at the way God knows when to send a special gift of encouragement at just the right time! It might be in a dream, a lost letter, a memory, or something found that we'd forgotten about.

    My grandmother was from a town in Michigan. And summer after summer I enjoyed staying with my grandparents as a young child. I was from the city and loved the small town where they lived. People knew everyone, their children, their pets, their ancestors.

    Grandma was always using her hands for something exciting …She would make sandwiches and we'd have tea parties, plant flowers and carefully tend them. She loved knitting sweaters as well as making beautiful quilts　for her grandchildren. I remember the small thimble ( 顶 针 ) she would place on her finger while doing her needlework.

    A few years ago, when Grandma left this earth for her new residence in Heaven, I bid farewell to my loving grandmother. How quickly our lives can change! We had just had tea together a couple of months earlier, on her 91st birthday. I missed her very much, but I noticed it mostly on my birthdays, because there was no card from Grandma. She'd never forgotten my birthday!

    On one particular birthday when I was feeling a little low, something happened and made me feel as if she was sharing that special day with me. I was arranging some colorful pillows that she had made, and suddenly I felt something inside one pillow; it was small and hard. I moved the object to a seam (缝) that I carefully opened, and, to my delight, out came a tiny silver thimble!

    How happy I was to find something that had been a part of her! Not realizing k had fallen off her finger, I pictured her sewing h into that little pillow that I just happened to fluff (抖松), to place on my bedspread (床罩) that day. I carefully laid the thimble alongside the others Id collected over the years. What a precious memory of a very special lady who, somehow, I knew, was laughing in delight at sewing her thimble into my pillow. I heated the kettle and made some tea, using my best china, as Grandma always did, and then enjoyed my tea and Grandma's thimble. What a wonderful birthday that was!

    Plastic waste has polluted the Arctic. Two new studies have spied bags, fishing rope and tinier bits of rubbish in the Barents Sea. This sea sits north of Norway, Sweden, Finland and Russia. It mixes with the Arctic Ocean, which is even farther north.

    Plastic waste in the Arctic could harm wildlife and may hint that large volumes of human rubbish are collecting there, says Melanie Bergmann. She is one of the scientists who spotted the waste. She studies Earth's oceans at the Alfred Wegener Institute in Bremerhaven, Germany. She first started counting bits of plastics in the Barents Sea because she kept spotting signs of the stuff there in images taken with deep-sea cameras.

    Bergmann and her colleagues counted pieces of plastic from an icebreaker, a boat designed to break through large blocks of ice in very cold waters. They also tracked plastic pieces they saw during helicopter rides over Arctic waters. The team found 31 pieces of plastic. “That doesn't seem like much, but it shows us that we've really got a problem, one that extends even to this remote area, far from civilization,” Bergmann says. She and her colleagues described their findings October 21 in Polar Biology.

    Another team has also been counting plastics in the area. Those scientists took water from the Barents Sea and counted the number of smaller bits of plastics, called microplastics.

    Plastic in the ocean is dangerous to animals. Some may get caught in rope or bags. And wildlife may swallow bags and other plastic bits. That makes them feel full. But some may eventually starve because they are not getting the nutrients they need to live. Sometimes plastics also may break down in an animal's body and release poisonous chemicals. If another animal later eats the one that swallowed plastic, it too can end up with poisonous chemicals in its body. This, in turn, can travel up the food web, endangering predators (肉食动物) — even people.

    I.M. Pei, the Chinese-American, who was regarded as one of the last great modernist architects, has died at the age of 102.

    Although he worked mostly in the United States, Pei will always be remembered for a European project: His redevelopment of the Louvre Museum in Paris in the 1980s. He gave us the glass and metal pyramid in the main courtyard, along with three smaller pyramids and a vast subterranean (地下的) addition to the museum entrance.

    Pei was the first foreign architect to work on the Louvre in its long history, and initially his designs were fiercely opposed. But in the end, the French—and everyone else—were won over. Winning the fifth Pritzker Architecture Prize in 1983, he was thought as giving the 20th century "some of its most beautiful inside spaces and outside forms … His talent and skill in the use of materials approach the level of poetry."

    After studying architecture at the Massachusetts Institute of Technology and Harvard, Pei set up his own architectural practice in New York in 1955.

    Designing the John F. Kennedy Presidential Library & Museum in 1964 established him as a name. His East Building of the National Gallery of Art in Washington in 1978 changed people's ideas of a museum. The site was an odd trapezoid (梯形) shape. Pei's solution was to cut it in two. The resulting building was dramatic, light and elegant—one of the first crowd-pleasing cathedrals of modern art.

    Though known as a modernist, and notable for his forms based on arrangements of simple geometric (几何的) shapes, he once urged Chinese architects to look more to their architectural tradition rather than designing in a western style.

    In person, I.M. Pei was good-humored, charming and unusually modest. His working process was evolutionary, but innovation (创新) was never an intended goal.

    "Stylistic originality is not my purpose," he said. "I want to find the originality in the time, the place and the problem."

    I'm a speaker and give hundreds of speeches every year. I spoke about appreciation (感激) last month and I used this quote by Albert Schweitzer "Sometimes our light goes out but is blown again into flame by meeting with another human being. Each of us should express the deepest thanks to those who have relighted this inner (内心的) light."

    I asked my audiences to shut their eyes and think about someone who, at some time in their lives, has relighted their inner light. Then I left the room in silence for several minutes. It was always a meaningful experience as they remembered the joy they felt from another person.

    One day, a gentleman came up to talk with me and thanked me for creating a new awareness (意识) in him. He said he thought of his eighth-grade history teacher because she was everyone's favorite teacher and had really made a difference in all of their lives. Several days later, the gentleman found his history teacher and he wrote to her. The following week he received this letter:

    Dear John,

    You will never know how much your letter meant to me. I am 83 years old, and I am living all alone in one room. My friends are all gone. My family's gone. I taught 50 years and yours is the first "thank you" letter I have ever gotten from a student. Sometimes I wonder what I did with my life. I will read and reread your letter until the day I die.

    The gentleman was sad, "She is always the one we talk about when we have a get-together. She is everyone's favorite teacher—we love her! But no one had ever told her until she received my letter…"
