Children in kinder gardens have a lot of chances to interact（互动）with other children at their age．If your child is not in it, it can be fun and helpful to create chances to play with others．Here are some things you can do to support your child's early partner relationship.

    Schedule regular playmates.

    Start when your child is around one year of age, set aside a few times a week for playtime with partners．{#blank#}1{#/blank#} .Even so, you still might want to give your baby a chance observe and communicate with children who are at the same developmental level.

    Join a playgroup.

    Many communities have organized playgroups for young children．{#blank#}2{#/blank#}，and learn to feel comfortable in a new setting．As an added benefit, while your child plays, you can talk with other parents who have children the same age as your own.

    {#blank#}3{#/blank#}

    You can organize a playground in your own home．It may involve just one other child, or as many as three or four．{#blank#}4{#/blank#}.Remember: safety first.

    Offer guidance when needed.

    If you see a child playing in a way that might hurt another, certainly you need to help her find a safer way to have fun．{#blank#}5{#/blank#}．But remember that some children need to watch for a while before they feel comfortable joining in —encourage everyone to join the fun, but don't push.

    Reducing the amount of sleep affects students' performance at school. An American study asked schoolteachers to look at the effects of sleep restriction（限制） on children between six and twelve years of age. The teachers found that children who stayed up late had trouble thinking clearly and had more learning problems.

    {#blank#}1{#/blank#} Doctor Fallone now works at the Forest Institute of Professional Psychology in Springfield, Missouri. He presented the results last month at a science reporter conference in Washington, D. C. The Publication Sleep also reported the findings.

    The teachers were asked to complete weekly performance reports on seventy-four schoolchildren. The study lasted three weeks. During that period, Doctor Fallone and his team controlled the amount of sleep the children received.

    {#blank#}2{#/blank#} During another week, every child was kept awake later than normal. Each night, the youngest boys and girls had less than eight hours of sleep. The older ones were limited to six and a half hours. During the final week of the study, each child received no less than ten hours of sleep a night.

    The teachers were not told about how much sleep the students received. The study found that students who received eight hours or less had the most difficulty remembering old information. {#blank#}3{#/blank#}

    The study did not find that sleep restriction caused hyperactivity(极度活跃) in the children. {#blank#}4{#/blank#}

    Doctor Fall one said that the results provided experts and parents with a clear message: {#blank#}5{#/blank#}

    Most people have some regret that they just can't seem to get rid of. But holding on to regret about the past that can't be changed can have a bad impact on the possibility of a happy future. Regret is a waste of time, emotion and energy. To make sure that your life is a successful one, you need to take action to live in a way that you have no regret holding you back.

    Some people make very big decisions with very little consideration at all, and as a result they often regret their decisions. Before choosing a college major, getting married or accepting a job, you must think about all conditions carefully and make a conscious decision rather than a careless one. Big decisions aren't the only ones that require forethought, though. Before you become angry and say something you will regret later, think about what you're going to say.

    Some of things will be easy to do and some will be hard, but keep your eyes on the prize of living a successful life without regret, and you'll find that achieving your goals might be easier than you think. But don't just daydream about those goals—make an actual list, written down in black and white, and refer to it now and then to see what you have left to do.

    When you're feeling happy and full of energy, taking care of yourself isn't a problem. But in those days when you feel like crawling beneath the bed and never coming out again, you still must take care of yourself. You can do what you want and don't get angry with yourself about your shortcomings. On the contrary, you just admit them and try to change them and move on. Improving your mental health is just as important as taking care of yourself physically.

    Keep those who are important to you very close and be sure to let them know how important they are to you. Family, friends, co-workers and people who are as close as your families are your lifelines that you can depend on whenever you need them to help you remember what's important in life. You should make sure of repairing your relationships with your friends if something bad happens.

    Last but not least, learn to give yourself some relaxation and not to waste your time regretting things you cannot change. Treat those things properly and move on. Life is hard, but it is precious. Don't waste time regretting the past, or your future will get here before you know it.

Why the youth sense anger in faces

    We tend to believe that older people are more positive and younger people are more sensitive to social cues (暗示).

    Recently scientists investigated this idea by testing 10,000 men and women. They wanted to see if age affected a person's ability to identify facial emotions, such as fear and anger.

    The researchers from McLean Hospital in the US used a Web-based platform to collect happiness data. It showed the participants two headshots (头部特写)of random people. They were then asked to identify which subject was angrier, happier, or more fearful.

    The research found that younger people were able to better identify angry and fearful facial cues than older people.

    "From studies and anecdotal evidence, we know that the everyday experiences of an adolescent are different from an older person, but we wanted to understand how these experiences might be linked with differences in basic emotion understanding,wrote Laura Germine, the study's senior author.

    But what is it that makes young people more sensitive?

    "This is the exact age when young people are most sensitive to forms of negative social cues, such as bullying," Lauren Rutter, the study's lead author, told Science Daily. "The normal development of anger sensitivity can contribute to some of the challenges that arise during this phase of development.

    On the contrary  across the whole 10,000-person survey, researchers found no decline in the perception (感知)of happiness among older participants.

    "What's remarkable is that we see declines in many visual perceptual abilities as we get older, but here we did not see such declines in the perception of happiness, Germine told Neuro Science News.

    She added that these findings fit well with other researches, showing that older adults tend to have more positive emotions and a positive outlook.

    Following the paper's release, Rutter told Neuro Science News that gathering their primary research online allowed the team to research into a "much larger and more diverse sample set" than previous studies.

The urge to share our lives on social media

    People have long used media to see reflections of themselves. Long before mobile phones or even photography, diaries were kept as a way to understand oneself and the world in which one lives. In the 18th and 19th centuries, as diaries became more popular, middle-class New Englanders, particularly white women, wrote about their everyday lives and the world around them.

    These diaries were not a place into which they poured their innermost thoughts and desires, but rather a place to chronicle (记录) the social world around them. The diaries captured the everyday routines of mid-19th-century life, and women diarists in particular focused not on themselves but on their families and their communities.

Diaries today are, for the most part, private. But things were different for these New England diaries. Young women who were married would send their diaries home to their parents as a way of maintaining kin (血缘) relations. When family or friends came to visit, it was not uncommon to sit down and go through one's journal together.

    Diaries are not the only media that people have used to document lives and share them with others. We have long used media like photo albums, baby books and even slide shows as a means of creating traces (痕迹) of our lives. We do this to understand ourselves and to see trends in our behaviour. We create traces as part of our identity and part of our memory.

    Sharing everyday life events can strengthen social connection and intimacy (亲密感). For example, you take a picture of your child's first birthday. It is not only a developmental milestone: the photo also strengthen the identity of the family unit itself. The act of taking the photo and proudly sharing it further reaffirms (再次证实) one as a good and attentive parent. In other words, the media traces of others figure in our own identities.

    Today's social media platforms are, by and large, free to use, unlike historical diaries, which people had to buy. Today, advertising subsidises (补贴) our use of networked platforms. Therefore these platforms encourage use of their networks to build larger audiences and to better target them. Our pictures, our posts, and our likes are commodified—that is, they are used to create value through increasingly targeted advertising.

    Instead of social media merely connecting us, it has become a craze (狂热) for information, continually trying to draw us in with the promise of social connectivity—it's someone's birthday, someone liked your picture, etc. There's a multibillion-dollar industry pulling us into our smartphones, relying on a longstanding human need for communication.

    The urge to be present on social media is much more complex than simply narcissism (自恋).

    Social media of all kinds not only enable people to see their reflections, but to feel their connection as well.

    According to the recently published cultural mindset study from Culture Trip, 60% of people in the US and UK say that their outlook on life is shaped by influences from different cultures. At the same time, the economic landscape of the last decade has resulted in younger generations being more interested in collecting experiences than possessions.

    Welcome to the "new culture economy"

    The collision of the two trends—globalization and the experience economy—has caused a new travel concept with cultural curiosity at its heart. This is the "new culture economy". The phenomenon is having a profound impact on people's interactions and definitions of cultural exploration and presents an incredible commercial opportunity.

    Education, travel, exposure to other customs and the cultural mashup that energes are the more influential social effects of globalization. More than half of respondents from the cultural mindset study have friends living overseas, while 78% have friends or family of different nationalities. Besides, the confines of student debt and unaffordable housing have created a shift in spending patterns, and so a new set of values has emerged in which experiences matter more than ownership.

    Why we travel

    People's social networks expose them to digital influencers and keep them connected to friends or family living in other parts of the world. The combination of these cultural, social and personal drivers has helped us to identify four cultural mindsets.

    ⒈Culturally aware—The motivation to travel among this group is anchored in pleasure. They seek out familiarity and select destinations close to home or reflective of their own culture.

    ⒉Culturally curious—Those with this mindset travel to discover new things and disrupt their everyday routines. They seek some familiarity, but also want to explore boundaries. They want to be seen as someone who is interested in culture, but this is often expressed in terms of visual interest and well－known sites.

    ⒊Culturally immersive—For this group, travel is all about adventure and personal growth. They want to be seen as highly cultured and as "explorers"; they are happy to celebrate when things go wrong, which they see as the key ingredient to making memories.

    ⒋Culturally fluid—The group's identity is shaped by their familiarity with travel. They feel at home everywhere and have adopted a hybrid cultural identity. Memories are often tied to experiences with people that represent the culture they are travelling to rather than sites.

    The environmental trade－off

    The cultural mindset research also sheds light on how people perceive the effect of tourism on the environment and the measures they take to reduce their impact. Two in five millennials—more than any other generation—worry that tourism has a negative impact on the environment and over a third limit how much they travel to reduce their impact.

    While most people won't control their desire to travel entirely, good news is that those who see the world are also the ones taking measures in their everyday lives to reduce their impact on the environment.
