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 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.”

    Speaking in public meetings is necessary for many students and employees. As well, it is a difficult task for them, especially for non-native speakers. A great many researchers have made efforts to help foreign language learners to improve the approaches.

    Charles LeBeau is a public speaking professor and consultant. Currently, he teaches at two universities and at the Toshiba International Training Center. He has also written books on the subject. English language learners around the world use his book Speaking of Speech.

    In Speaking of Speech Mr. LeBeau says a simple approach helps the learners. So, the professor divides public speaking into three parts: the physical message, the visual message, and the story message. He says, “The central thing to remember about public speaking or presentation is that it's a very complex communicative activity. For non-native speakers it's a really scary activity. So to make that more simplistic and easy for them, the approach that I've taken is to simplify and break it down. First if we look at presentation, what's going on? There are basically three messages that the presenter is giving the audience at the same time. There's what I call the physical message, namely body language. It's the way that my body, as a speaker, is talking to the audience. Then there's also the visual message. The visual messages are the slides that we now make and show the audience. The third message is the story message, which is the content of our presentation. The story message is the verbal message, what we say to the audience. The story message also includes how we organize our ideas to present to the audience.”

    He says the simple approach to breaking down the parts of public speaking has proved itself. He says learners improve quickly and do a good presentation after a few days of study.

    When we talk about famous UK writer Agatha Christie, it seems that her famous detectives Hercule Poirot and Miss Marple are must-reads. So, of course, are her best-selling novels Murder on the Orient Express (1934) and Death on the Nile (1937).

But when the readers around the world were asked to name their favorite Christie novel to mark her 125th birthday on Sept 15, And Then There Were None (1939) topped the list, reported The Guardian.

    It may surprise you to learn that it is a crime novel without a detective. What it does have is suspense (n.悬念) and a very sinister (adj.邪恶的) atmosphere. It is “on a knife edge”, as Mathew Prichard, Christie's grandson, told the newspaper.

    Ten people get an invitation to come to a house on a small island near Devon in South West England. Nobody refuses these invitations since each one promises something the person wants: a job, a holiday, a chance to meet up again with an old friend.

    These people are all responsible for deaths. Some are directly responsible, others are responsible because of what they did not do. Anthony James Marston, for instance, killed two children while driving dangerously. He did not feel guilty and actually complained when he was banned from driving. Another, Emily Caroline Brent, is a harsh person who threw out a young servant for becoming pregnant while unmarried. The servant later killed herself.

    When they arrive at the house they are played a recording. The voice gives details of the wrongdoing of each of the guests. Starting with Marston, each is killed in a way that fits their crime. The series of deaths is completed with a hanging, “and then there were none”, as the title suggests.

    Christie can be quite a predictable writer. Some of her stories are a little unoriginal. But this book is full of clever writing. Look it up to find out what this hugely successful mystery writer, the “Queen of Crime” as she was called, could do at her best.

    On average, primary school children in England have at least three sugary snacks a day, Public Health England (PHE) found. This means that the sugar they consume is three times more than the recommended maximum.

    Children between the ages of 4 and 10 consume 51.2% of sugar from unhealthy snacks. PHE has launched a campaign, Change4Life, to encourage parents to look for healthier snacks of no more than 100 calories, and to limit them to two a day. The campaign advises parents to give their children a maximum of two snacks a day, with each containing no more than 100 calories. The campaign will also offer parents special suggestions on a range of healthier snacks—ones with 100 calories or fewer—at selected supermarkets, PHE said.

    PHE said it had also improved its app so that it could mark the content of sugar, salt and fat in food and drinks. Dr Alison Tedstone told the BBC she hoped the campaign would help parents to choose healthier snacks for their children. “If you wander through a supermarket, you can see much more goods being sold as snacks than ever before,” she said, “It's a common phenomenon that kids' lunchboxes are full of snacks, leading to a lot of calories for lunch. Our research shows that parents usually appreciate a rule of thumb (经验法则). However, they are surprised to know how much sugar their children are consuming in snacks now.”

    Justine Roberts, founder of Mumsnet, said, “The intake (摄入量) of sugar that kids are getting from snacks and sugary drinks alone is pretty astonishing, and it can often be difficult to distinguish which snacks are healthy and which are not. The rule of thumb from Change4Life can help parents make their decision correctly and wisely. ”

Over the years, electronic commerce or e-commerce has grown rapidly. The rise of e-commerce large enterprises such as Amazon and Alibaba in the mid-90s changed the face of the retail (零售) industry. E-commerce may be thought of as an open, global marketplace or a digital version of mail-order catalogue (目录). Nearly every imaginable product and service is available through e-commerce dealings these days.

Many young entrepreneurs have dived into the e-commerce world, ambitious and hoping to succeed. Some, like Mitchell Zvagelskiy. Zvagelskiy is the co-founder of Scale Online, a fast-growing startup in California and runs several e-commerce stores. Zvagelskiy and his business partner began opening online stores and building a team to grow them, allowing the stores to earn as much as $100.000＋ in monthly revenue. Zvagelskiy owes his success to teamwork and his willingness to seize opportunity.

"Being able to do this all by the age of 20 is something I didn't expect and would not be able to do if I constantly listened to other people and just went the typical college then job route," he said. "Life can change fast if you change fast."

Thanks to the rapid success of his YouTube channel, Mitchell has been able to not only make great profit from his companies, but help others in starting and growing their own e-commerce stores too. "My meaning of success arises from my relationships with other people," he said. "By focusing on building strong relationships with others, I'm able to partner up and work with like-minded individuals in finding market opportunities and solving whatever problems people are facing."

A recent study by UK researchers has shed light on a phenomenon termed "plant blindness," which contributes to the widespread but mistaken belief that plants are perceived as less vibrant or alive compared to animals.

It was not established that plant blindness is an innate trait; instead, the root cause appears to be the significantly diminished interaction with the natural world in societies that have become highly urbanized. The research indicates that a decrease in prior exposure to plants leads to a cycle of inattention.

Urban cultures exhibit a well-documented incidence of plant blindness. Children are often observed to regard plants as less significant than animals, especially during their early years, and they have difficulty recognizing a diverse range of plant species. Both educators and students have reported varying levels of knowledge about plants, with primary school teachers lacking a background in science being particularly affected. In contrast, older individuals tend to possess greater plant knowledge, likely due to their increased participation in outdoor activities.

Thirty-five studies have concluded that the process of urbanization or modernization has had a negative impact on people's understanding of plants. The value of plant gathering has diminished due to an increased reliance on urban services and a cash-based economy. Additionally, the time available for outdoor activities has been curtailed by work and school commitments. These factors have also reduced family time, which in turn has adversely affected the oral transmission of plant knowledge to younger and older family members.

Stagg has suggested that rather than a cognitive impediment to the visual recognition of plants, individuals residing in highly industrialized nations suffer from a lack of attention to plants due to a reduction in relevant exposure.

To disrupt the cycle of plant inattention, Stagg emphasizes the importance of exposing people to diverse ecosystems and demonstrating the direct benefits of plants to humans, as opposed to the indirect benefits derived from their industrial use or advantages to distant, traditional communities. Engaging with edible and practical plants in local settings can be instrumental in this regard. The level of botanical knowledge among younger generations is directly linked to their perception of the usefulness of such knowledge in their lives.
