The baby monkey is much more developed at birth than the human baby. Almost from the moment it is born, the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large, warm, and soft object in its environment, particularly if that object also gives it milk. After a week or so, however, the baby monkey begins to avoid newcomers and focuses its attentions on “mother” — the real mother or the mother-substitute(母亲替代物）.

During the first two weeks of its warmth is perhaps the most important psychological（心理的） thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother-substitutes — one covered with cloth and one made of bare wire. If the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after birth the baby monkeys picked the warm wire mother-substitutes as their favorites. Thereafter they switched and spent most of their time on the more comfortable cloth mother

    Why is cloth preferable to bare wire? Something that the Harlows called contact（接触的） comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers' skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire doesn't“rub”as well as does soft wire cloth. Prolonged（长时间的）“contact comfort” with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk.

    According to the Harlows, the basic quality of a baby's love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no matter how interesting they might be. It screams in terror and curls up into a fury little ball. If its cloth mother is now introduced into the playroom, the bay rushes to it and holds onto it for dear life. After a few minutes of contact comfort, it obviously begins to feel more secure. It then climbs down from the mother-substitute and begins to explore the toys, but often rushes back for a deep embrace（拥抱）as if to make sure that its mother is still there and that all is well. Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding on to its “mother.”

    Humans were designed to stand upright(直立). And yet in this modern world, too many of us spend our days with our heads lowered for a simple reason: we're staring at the tiny screen of a smart phone.

    People spend an average of 2 to 4 hours each day with their neck bent while shooting off emails or texts. That's 700 to 1,400 hours a year. The success of social media has led to a rapid development of bad smart phone posture.

    The average adult head weighs 10 to 12 pounds when it's in the upright position. However, because of the gravity, bending your head at a mere 15 degree puts 27 pounds of pressure on your spine(脊椎)；a 30 degree neck bend could equal(等于) 40 pounds of pressure; a 45 degree bend adds the force of 49 pounds, according to the research from Dr. Kenneth Hansraj from New York. These stresses may lead to many problems.

    It's no secret that correct posture is better for your back. According to the researchers, good posture is described as ears aligned(成一条直线) with the shoulders. In proper alignment, spinal stress disappeared. It is the best position for the spine. Standing tall doesn't just make you look better; it improves your health, too. Other studies have found good posture has even been connected to ways of behaving. People who have poorer posture often have poorer physical and emotional health.

    The researchers describe bad posture（姿势）as “the head in a forward position and the shoulders dropping forward in a rounded position”. Bad posture has been connected to many medical problems, including headaches and other problems, depression and heart disease. This is why Hansraj said it's important to be mindful of your smart phone posture. While it is nearly impossible to avoid the technologies that cause these problems, people should make an effort to look at their phones with a correct posture.

    Parents in Spain are being urged to go on a weekend homework strike this month in protest against the unacceptable amount of after-school tasks their children are given.The homework load of Spanish children has long been a sore point with some parents,who argue that the burden is too great,places too much pressure on pupils and eats into family time.

    According to a study by the Organization for Economic Co-operation and Development (OECD),Spanish 15-year-olds have 6.5 hours of homework a Week compared with an average of 4.9 across the 38 OECD countries. The Spanish Confederation of Associations of Mothers and Fathers of Students (Ceapa) is calling on parents whose children attend Spanish state schools to boycott weekend homework in November.

    "We've lost a bit of common sense in this country when it comes to talking about education and we've got a system in which boys' and girls' free time has disappeared",said Jos Luis Pazos,president of Ceapa."Schools are passing on tasks to families that they shouldn't be.It starts with children from the ages of three to six doing half an hour's homework every day.For us,that's an unacceptable situation".

    Pazos said Ceapa disagreed with the belief that children should endure huge amounts of homework in the hope that it would ensure them a better future.They should be.happy when they're little and that life isn't just about someone telling you that you have to suffer inexplicably（难以理解地）.The model needs to change because society has changed.

    Schoolchildren have to fit their homework around the school day,which varies from region to region and school to school,but starts early from around 8 am or 9 am and finishes anywhere between 2 pm and 5 pm.However,schools are increasingly using an 8 am-2 pm timetable to save money and in the face of evidence that suggests the longer hours do not yield better results.

    A spokesman for the education department of Madrid said homework was a matter for individual schools rather than regional governments.They're the ones who know best what the need is in each case.

    Karen Bystedt was born in Israel, but lived in London and California as a child. In 1982, as a photography (摄影) student at New York University, she was photographing male models for a book when she came across an ad featuring Andy Warhol, a very famous artist. She thought it would be really great to put him in her book.

    So she called Andy Warhol at his studio in Union Square and asked if she could photograph him.

Two weeks later, Bystedt took a rented Hasselblad camera and lights to Warhol's famed "Factory" on 14th street. She ended up taking 36 pictures, and published two in her book, Not Just Another Pretty Face, published in 1983. Warhol came to its launch (发行) party—and that was the last time she saw him.

    A few years later, she packed the portraits in a box and moved to Los Angeles. But after she'd gotten settled, she couldn't find them. She couldn't remember whether she had given the photos away or just left them in some forgotten storage unit. Either way, she thought they were lost forever.

    In 2011, Bystedt became determined to find the missing films(底片). She spent two weeks going through two old garages, where she had put a bunch of belongings decades before. In a cardboard box, she found ten of the original films, covered in dust. She and a friend spent four months digitizing and cleaning the images up, pixel(像素) by pixel.

    Bystedt was not content to merely publish the unseen photos. She invited contemporary artists to paint over and around her Warhol pictures, breathing new life into her old work. So she began reaching out to artists, seeing if they would be interested in putting their own stamp on the pictures.

    The responses was overwhelming. Bystedt's new exhibit, "The Lost Warhols," opened on May 1, 2018 at 178 Sixth Avenue in Soho, New York, included 66 different interpretations of her portraits from 34 artists.

Scholastic Art: What is your job?

Jayson Fann: I build human-sized nests all over the world.

SA: Can people sit in your nests?

JF: Yes! People have dinner parties in my nests. They read and relax in them. Some of my nests even have several rooms. My nests are even used as hotel rooms.

SA: How do you make a nest?

JF: First, I make a design for the nest. Then I review the design with my client（客户）. After the design is final, I collect wood and work with a team to build it.

SA: What do you use to make your nests?

JF：I use eucalyptus（按树）wood， which is soft and easy to bend when it is young and freshly cut. But when it dries, it becomes extremely hard. So it holds its shape and can support weight. But the structure's strength also comes from the engineering -- how I weave the wood, and how I join major sections by bolting（用螺栓固定）them together.

SA: What makes a great nest design?

JF: Placement is important. The lines of the branches（树枝） create movement and energy, resulting in a cleaner, simpler background -- such as smooth stone or the sky -- which really fits the nest. For me, it's all about balance.

SA: What skills do you need for your job?

JF: You have to be able to draw and use different artistic tools. But you also have to know how to speak to people -- your clients and the people who work for you.

SA: What inspires you?

IF: I love to see how other artists, like Andy Goldsworthy, take common and natural materials and make something special with them.

SA: What is the best part of your job?

JF: I get to be creative in a way that doesn't harm the environment!

    When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.

    These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. "Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society," said George Vaillant, the psychologist (心理学家) who made the discovery. "And because they felt good about themselves, others felt good about them."

    Vaillant's study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men's mental-health scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

    The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.

    Working—at any age—is important. Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn't everything. As Tolstoy once said, "One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work."
