If you've not heard that the decade-old princess-culture is causing problems—especially if you're a parent—you must be actively working to avoid it.

    The latest study adding fuel to the fire comes out of Brigham Young University and finds that the Disney princess obsession can be harmful to girls.

"I think parents think that the Disney princess culture is safe. That's the word I hear time and time again—it's safe." Lead study author Sarah M. Coyne of the Mormon institution in Utah noted in a press release. "But if we're fully jumping in here and really embracing (accepting) it, parents should really consider the long-term impact of the princess culture."

    So, what's the problem this time around? Same as always, confirmed the study, published in the journal Child Development, which involved the assessment of 198 preschoolers: Lots of engagement with princess culture (whether through moves or toys) can lead to gender-stereotypical(性别定性) behavior as well as self-critical body image.

The strict gender stereotypes can hold girls back. "They feel like they can't do some things," Coyne said, "They're not as confident that they can do well in math and science. They don't like getting dirty, so they're less likely to try and experiment with things."

On the other hand, "Disney princesses represent some of the first examples of exposure to the thin ideal," Coyne said. "As women, we get it our whole lives, and it really does start at the Disney princess level, at age 3 and 4."

So, what should a parent do? Try his or her best to avoid all princesses for the entire of a girl's childhood? I'd say, have moderation in all things, have your kids involved in all sorts of activities, and just have princesses be one of many, many things that they like to do and engage with." Coyne suggested. "This study has changed the way I talk to my daughter, the things I focus on, and it's been really good for me as a parent to learn from this study," Coyne said. "I usually can't say that my research findings have such a personal impact on my life."

    I remember my mother as a strong woman. She came to America when she was 12—old enough to remember her language, she achieved scores and grades high enough to be admitted to Duke University. With a degree in computer science, she finally became the manager of a company in New York. My mother could give fluent speeches, say “wolves” correctly.

    It was my mother who always stressed the importance of language. From the time I was born, I was read to. I would fall asleep to the sounds of my parents' voices, whether it was my dad's softly accented, or my mother's clear English. The flow of language was unbroken, and whether in Chinese or English, the stream of communication flowed through our house.

    One October morning in sixth grade, after my mother had left to catch the train to the city, I left the house for the bus stop. I was surprised when I saw our car, the door hanging open. As I drew closer, I saw my mother lying on the ground.

    In the hospital, it was hard to believe that the lady who lay before me was my mom. My mother could not remember my name. As the leaves changed colors, it became clear that the stroke had created a wall between my mothers mind and mouth: her mind was not any less dear, but the words she spoke were not what she meant.

    The battle my mother faced taught me the importance of language. Without it, identity does not exist; relationships cannot be formed; stories cannot be told; directions cannot be given, and knowing anything about anyone is impossible. Without language, communication cannot take place. Without language, one cannot express the beauty of a sunset or the kindness of a stranger. The world would pass us by in silence.

    Enough sleep is important to health. The amount of sleep needed depends on the age of the person and the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight hours are enough for the health of grown-ups. Some can do with less than this amount, but others may need more. Every person knows his own need. It is then a matter of good judgement to satisfy his need. Sleep should always be enough to make one bring back his strength and get ready for a day's work.

    Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation (放松).

    Ability (能力) to sleep lies largely in habit. The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance (避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.

    A bath at bedtime, neither hot nor cool but of body temperature may be helpful to sleep. Sleep-producing drug (药) should never be taken except when suggested by a doctor.

    Humans have been keeping animals as pets for tens of thousands of years, but Dr Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.

    “Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”

    This may not sit well with pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don't have to feed it, you don't have to walk it, it won't make a mess in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.

    It's not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart machines. People give their cars names and kids give their toy animals life stories. It's the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.

    As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn't need food, water or exercises, perhaps it will change how humans care about other living beings,” he said.

    So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets needn't have a heartbeat might not be a far-fetched dream.

    With her pretty face and soulful voice, Zhang Bichen was thought a possible champion when she first set foot on the stage of the TV show The Voice of China.

    On Oct 7, 2014, the 25-year-old girl won the fierce competition and received the title of the “Voice of the Year”. Zhang's dream of being a singer star came true as last. What impressed people was not only Zhang's singing skills, but her willingness to make an effort. “I gained the opportunity to sing on The Voice of China,” she said.

    In fact, being a singer has always been her dream. She wanted to apply to a college for singing, but her parents insisted that she should have an easy job after graduation because she did very well at school. So Zhang gave in to her parents and learned French at university. However, in the first year of her college, she was discovered by a South Korean company when she entered a singing competition. To realize her dream, Zhang signed a contract（合同）with the company, started her career in South Korea, and became a member of a band.

    “My company had rules that did not allow us to use cell phones. During the first few months after I arrived in South Korea, a totally unfamiliar country, I felt terribly homesick. But I could only phone my parents in the restroom when nobody noticed.” Zhang said. “When I did not have much income, I had to eat noodles every day for months.”

    It was her positive attitude and outgoing character that helped her through. “When I feel down, I tell myself it is not winning or losing that matters. The most important things are standing on the stage and singing for people.” she said.

    Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.

    We experience this tiredness in two ways: as start-up fatigue(疲惫) and performance fatigue. In the former case, we keep putting off a task because it has either too boring or too difficult. And the longer we delay it, the more tired we feel.

    Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The solution is obvious though perhaps not easy to apply: always handle the most difficult job first.

    Years ago, I was asked to write 102 essays on the great ideas of some famous authors. Applying my own rule, I determined to write them in alphabetical(按字母顺序), never letting myself leave out a tough idea. And I always started the day's work with the difficult task of essay-writing. Experience proved that the rule works.

    Performance fatigue is more difficult to handle. Though willing to get started, we cannot seem to do the job right. Its difficulties appear so great that, however hard we work, we fail again and again. In such a situation, I work as hard as I can-then let the unconscious take over.

    When planning Encyclopaedia Britannica (《大英百科全书》), I had to create a table of contents based on the topics of its articles. Nothing like this had ever been done before, and day after dat I kept coming up with solutions, but none of them worked. My fatigue became almost unbearable.

    One day, mentally exhausted, I wrote down all the reasons why this problem could not be solved. I tried to convince myself that the trouble was with the problem itself, not with me. Relived, I sat back in an easy chair and fell asleep.

    An hour later, I woke up suddenly with the solution clearly in mind. In the weeks that followed, the solution which had come up in my unconscious mind provided correct at every step. Though I worked as hard as before, I felt no fatigue. Success was now as exciting as failure had been depressing.

    Human beings, I believe must try to succeed. Success, then, means never feeling tired.
