Every man wants his son to be somewhat of a clone, not in features but in footsteps. As he grows you also age, and your ambitions become more unachievable. You begin to realize that your boy, in your footsteps, could probably accomplish what you hoped for. But footsteps can be muddied and they can go off in different directions.

    My son Jody has hated school since day one in kindergarten. Science projects waited until the last moment. Book reports weren't written until the final threat.

    I've been a newspaperman all my adult life. My daughter is a university graduate working toward her master's degree in English. But Jody? When he entered the tenth grade he became a “vo-tech” student(技校学生). They're called “motorheads” by the rest of the student body.

    When a secretary in my office first called him “motorhead”, I was shocked. “Hey, he's a good kid,” I wanted to say. “And smart, really.”

    I learned later that motorheads are, indeed, different. They usually have dirty hands and wear dirty work clothes. And they don't often make school honor rolls(光荣榜).

    But being the parent of a motorhead is itself an experience in education. We who labor in clean shirts in offices don't have the abilities that motorheads have. I began to learn this when I had my car crashed. The cost to repair it was estimated at $800. “Hey, I can fix it,” said Jody. I doubted it, but let him go ahead, for I had nothing to lose.

    My son ,with other motorheads, fixed the car. They got parts from a junkyard, and ability from vo-tech classes. The lost was $25 instead of $800.

    Since that first repair job, a broken air-conditioner, a non-functioning washer and a non-toasting toaster have been fixed. Neighbors and co-workers trust their car repairs to him.

    These kids are happiest when doing repairs. They joke and laugh and are living in their own relaxed world. And their minds are bright despite their dirty hands and clothes.

    I have learned a lot from my motorhead: publishers need printers, engineers need mechanics, and architects need builders. Most important, I have learned that fathers don't need clones in footsteps or anywhere else.

    My son may never make the school honor roll. But he made mine.

    A fourth-grade teacher allowed one of her students to shave her head in the schoolyard, after bullies（仗势欺人者）teased him about his own short buzz cut（短寸头发型）. Tori Nelson got the idea after noticing that Matthew Finney, a shy boy from her homeroom at Winlock Miller Elementary School in Washington state, was standing outside his classroom crying and wearing a winter hat.

    Ms. Nelson could see the back of his neck had been shaved, and since Matthew usually had very thick brown curly hair, she realized that he'd had a haircut over the weekend. She asked him what was wrong, and he said he'd gotten a buzz cut for the summer. But this morning, a fifth grader on the bus made fun of him, and he didn't want to come to class and get teased by other kids. Ms Nelson tried to convince Matthew to come inside, but since school rules prohibit kids from wearing hats indoors he refused – explaining that he was afraid of showing his haircut to the other children in case they also made fun of him.

    Finally I said: "If you take off your hat and come to class, I'll let you give me a buzz cut, too," 'Ms Nelson told Yahoo Parenting. I figured it's just hair, and mine is already short anyway. I might as well get it shorter in time for the warm weather.'

    Matthew excitedly took her up on the offer, and Ms Nelson and another teacher gathered all the fourth graders together during break time. A school employee brought in scissors, which Matthew used to the cheers of his classmates, excitedly watching as his teacher's hair fell away onto the ground in the schoolyard.

    'It was a lot of fun for the kids, and it helped Matthew feel better about himself,' said Ms Nelson.' You have to do what it takes to reach children. Teaching isn't just about reading and writing, it's about self-esteem and accepting differences.'

    The European Parliament has approved a law banning a wide-range of single-use plastic items, such as straws and cotton buds by 2021. "Europe is setting new standards, paving the way(铺路) for the rest of the world," the European Commission's vice-president Frans Timmermans, who is responsible for sustainable development, said in a statement.

    The new plans come after the EC found that plastics make up more than 80% of marine litter, which has disastrous effects on wildlife and habitats. The EU parliament notes that because of its slow rate of breaking down, plastic residue(残余) has been found in marine species as well as fish and shellfish - and therefore also makes its way into the human food chain.

    Under the new European law, tobacco companies will be required to cover the costs for the collection of cigarette butts. Manufacturers of fishing tools will also have to pay for the retrieval(找回) of any plastic nets that have been left at sea. There's also a new focus on further raising public awareness, where producers of items such as tobacco filters(滤嘴), plastic cups, and wet wipes will be required to clearly explain to users how to appropriately dispose of them.

    The European Commission first suggested the ban in May, which was approved by member states in October. China last year banned the import of 24 varieties of solid waste, including types of plastic and unsorted paper, putting pressure on Europe to deal with its own waste.

    The World Economic Forum estimates that there are about 150 million tons of plastic in the world's seas. A study published in Science in 2015 suggested that between 5 and 13 million tons more are flowing into them every year. Research shows there will be more plastic than fish by weight in the world's oceans by 2050, which has encouraged policymakers, individuals and companies into action.

    Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.

    A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet (LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.

    According to Sari Nijssen, the study set out to answer the following question:" Under what circumstances would adults be willing to sacrifice robots to save human lives?" The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine.

    The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans.

    "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."

    My husband and I recently went to Disney World with our three children. We had a wonderful time. Besides, I experienced something that left a deep impression on me.

    Our children were excited about the attraction where children could drive the cars. They were so delighted that I decided to stand beside the track to get pictures of everyone as they drove past on the track.

    As I waited for them to drive by, I noticed a car with a father and his son who was about 7 years old. They rolled down the hill at the beginning, but suddenly the car stopped. The young driver looked nervous, "I can't do it." His father quietly said, "Yes, you can."

    "No. I can't!"

    "Yes, you can, son."

    The little guy was almost in tears, "I can't!" With deep patience, the father said, "Son, you can do this. I'm going to help you." A moment later, with the father helping his son, the two went smoothly (顺利地) on their way down the track.

    The scene brought tears to my eyes and it reminded (使想起) me of my dear father. Just like that little boy's dad, my father used to say the same words to me. Every time things got hard or when I experienced setbacks along the way, he would say, "Michelle, you can do this. I'm going to help you."

    Time and time again the words greatly encouraged me on the journey. I'm aware that I can't do things under my own power, but the words "Yes, you can" come beside me and give me wisdom and strength. As I benefited (受益) a lot from them, I often tell my children never to say "I can't" easily when they meet something difficult.

    Are you familiar with the greeting, "Can I add you on WeChat?" It seems like every time we meet new friends or colleagues nowadays, the first thing that springs to mind is adding each other on the app. Nevertheless, more than 80 percent of WeChat users report feeling stressed or anxious when they receive a large number of messages, according to a study done recently by the app's developer Tencent(腾讯). In other words, WeChat can overwhelm(使应接不暇) us, while also breaking down the boundaries between our work and private lives.

    Just think how easy it is now for bosses to hand out assignments during the holiday, so long as they have your WeChat contact. When you're at the cinema enjoying a romantic movie or having a barbecue in the backyard, you can never cut yourself off from the outside world unless you switch off your phone. Not to post something in WeChat Moments before replying to your boss first!

    Apart from interrupting your leisure time, WeChat can also reduce your productivity at work. For many office workers, logging in to WeChat on their computers at the start of the day has become routine. But what if browsing the Moments distracts us from doing the work? The app steals our time without us even noticing it, making us have the false belief that we are busy all the time.

    And as if that weren't bad enough, there're the "one-off" friends who take up space on our WeChat friend list. A handy way to check how many one-off friends you have is to take a look at your chat history with them. Sometimes, you only sent the initial friend requests so you could invite them to a WeChat group or inform them of something for your boss. Yet still, as your friend count(好友数量) ever goes up, it can make you feel the need to post selfies(自拍) and share details of your life in your Moments, just so you can stay up to date.

    With WeChat, all our spare time is swallowed up by the constant torrent of messages and our attention keeps getting diverted by Moments and pop-up ads. So it's time that we should do something to nip this problem in the bud.
