What makes a person a giver or a taker? The idea of “give versus take” takes shape in all relationships of our lives. We're either giving advice, making time for people, or we're on the receiving end. We alternate between the two based on different situations we face on a daily basis, it not an hourly one.

    According to Adam Grant, a professor at Pennsylvania University, most people are matchers. They make careful observations on takers and make it a point for them to pay something back. They hate to see people who act so generously towards others without receiving any reward. Actually, most matchers will try to promote and support givers so that they can get the good they deserve.

    Another professor named Hannah Rile Bowles, from Harvard University, led a study on the idea. She asked 200 senior managers to sit down in pairs where one person would act as the boss and the other as an employee to negotiate salary promotions. Male employees asked for an average salary of $146 k while the females asked for only $141 k. But why did they not bargain as hard as the men? Simply because they were more likely to be givers.

    As a woman, I do enjoy the act of giving up my time, my knowledge and my care and attention to others. I don't expect anything in return, but I do tend to pull myself away when I feel like I'm being taken for granted. I also tend to get upset when I see a loved one's continuous actions of kindness go unnoticed. So it's safe to say I'm 50% giver,35% matcher and 15% taker.

    I do know someone, however, who is 99% giver. They're devoting their time, sharing valuable insights and going out of their way for everyone who crosses their path. Although they've changed the lives of many people, they rarely see any of it returned. But the universe is slowly repaying them; they're now extremely successful, well known for what they do.

    Lots of people buy books and products from Amazon, an online seller. They offer and pay over the Internet and the books are shipped through the mail or a delivery service like FedEx.

    One day, people could get their Amazon deliveries from an “unmanned aerial vehicle”—a timely vehicle that looks like a toy helicopter. And instead of waiting days to get the parcel, it could be at the buyer's home in half an hour or less. The company is working on a fleet of tiny vehicles they call “Prime Air”. The vehicles are also known as “octocopters”. On their website, Amazon says, “One day, Prime Air Vehicles will be as normal as seeing a mail trucks on the road today.”

    The U.S.'s Federal Aviation Administration (FAA) is working on safety regulations for unmanned flying vehicles like the Prime Air copters. Those regulations will make sure the copters are able to fly safely where they need to go. Once the FAA has put its rules in place, which could be as early as 2016, Amazon will be ready with its fleet of tiny flyers. The process could take as many as five years.

    The new delivery service would likely be available only in the United States, at first. The copters the company is testing now can handle packages up to five pounds (2.3kg) and they have a range of 10 miles (16 kilometers).

    Other companies are also looking at using unmanned flying vehicles to deliver their products. For instance, Domino's Pizza in the U.K. released a video showing a “DomiCopter”, delivering a pizza. That video may have been a publicity stunt（噱头）. In any case, just like Prime Air's octocopters, the DomiCopters don't have clearance（许可）to take off just yet.

    Billionaire Bill Gates has offered the many thousands of graduates some career and life advice. Over a series of 14 tweets in his Tweeter posted last Monday, the world's richest man used the words “impact”, “happiness” and “progress”. He did not mention money. Instead, he told the graduates what jobs he would be looking for if he started out today.

“AI (artificial intelligence), energy and bio-sciences are promising fields where you can make a huge influence”, he wrote. Earlier this year, Gates—who famously dropped out of Harvard to found Microsoft—said that artificial intelligence had “ phenomenal” potential, and “anything connected with that would be an exciting lifetime career.” In the same speech at Columbia University, he said there is a huge growing demand in the energy field to develop reliable, cheap and clean energy.

    As well as urging new graduates to surround themselves with people who challenge you, teach you, and push you to be your best self, Gates reminded them to think of others, especially the less fortunate.

    He wrote that it had taken him decades to learn about the world's worst unfairness and described this lack of early understanding as his one big regret. “You know more than I did when I was your age,” he wrote, “ You can start fighting unfairness, whether down the street or around the world sooner.”

    He finished by asking graduates to consider the progress human has already made, saying that he believe the world is getting better. “ That matters because if you think the world is getting better, you want to spread the progress to more people and places.”

    We've all experienced the feeling that comes when your phone makes a sound to tell you that its battery level is low. It often comes at the worst times—when you're out on a trip and don't have a charger（充电器）, or when you're expecting an important phone call.

    Indeed, this feeling is so common that South Korean electronics manufacturer LG has given it a name: low battery anxiety（低电量焦虑）.

    According to a survey of 2,000 US adults conducted by the company last year, 90 percent of respondents said that they panic if their battery level reaches 20 percent or lower. And last month, UK telecommunications service provider found that around 15. 5 million Britons live in “constant fear” of their mobile phones running out of power, according to a survey by the company.

    “The problem is not about being unable to make calls, but is rooted in the fact that smartphones are now where we store digital memories,” noted the Daily Mail, However, battery worries don't just affect smartphone lovers. Many owners of electric vehicles also suffer from so-called “range anxiety”. This refers to the concern that the vehicle may not make it to its destination before the power runs out. Meanwhile, it isn't just low power that people worry about. A study carried out by South Korea's Sungkyunkwan University and China's City University of Hong Kong found that many of us also worry about not having constant access to our phone.

    This condition is known as homophobia, short for “ no mobile phone phobia（恐惧症）”. Symptoms include feeling uncomfortable when access to one's phone isn't possible, being unable to turn off your phone, and constantly topping up the battery to make sure it never dies.

    So, why do so many people treat their smartphone with such importance? The reason may be that they keep us connected to the people around us, and if we're unable to use our phone, we feel like we're cut off from our social life.

    With products with bigger batteries being released all the time-such as Xiaomi's Mi Max smartphone range or Tesla's Model S cars-battery anxiety may hopefully soon be a thing of the past.

Does your school have any problems with discipline? What happens when students step out of line? Here are some examples of bad behaviour:

    Playing truant(missing school without permission from parents).

    Stealing, smoking, hitting, swearing(说脏话), running, kissing.

    Cheating in exams.

    Calling a teacher or another pupil bad names.

    Not doing homework.

    Not listening or not paying attention in lessons.

    Wearing unsuitable clothes.

Here are some of the ways that UK school children can be punished:

Exclusion: a pupil is asked to leave the school and not come back. The pupil has to find a new school or a different method of education.

Suspension: a pupil cannot enter the building or attend lessons until the school has a meeting about their situation. Suspension can last from one to 45 days. The pupil is usually given work to do at home with a special teacher.

Detention: a pupil is asked to stay after school and work for 30—60 minutes before they Can leave.

Lines: a pupil has to write a sentence many times(e.g.100 or more)on a sheet of paper, e, g, “I must not shout in class”.

    Freya MacDonald, a 15-year-old pupil from Scotland, made the news when she refused to accept her school's punishment. Her family says that she was given 11 detentions for trivial things in class and coming into school through a fire door.

Freya says that repeated detentions disrupted her fight to an education under Scottish law and made it difficult for her to learn. She refused to return until the school respected her civil rights. She wants the headmaster and her teachers to sign a letter to promise this. Hundreds of schools in Scotland were told not to use detention as a punishment because of her legal action.

Many UK schools now give parents a home-school contract, explaining their discipline and rules. Parents must sign this document to agree that they accept the school's rules and discipline and that they are responsible for their child's behaviour.

    Your kids learn a lot from their friends—things you can't teach them, no matter how much you want to.

    Probably the most important thing kids learn is how to have peer relationships. As a parent, you can't do this, because you and your child aren't equals.

    For example, when you're sitting on your family room floor and your very young child asks you to pass him the blocks, you probably hand them right over. If your child is sitting with a peer and asks the same thing, though, he might not get what he wants.

    To succeed, your child will need to learn strategies for getting what he wants. For example, he might simply yank (猛拉) the toy out of his friend's hand. If he does that, he may learn that it's not the best way of getting what he wants because it leads to fighting and time­outs. The successful child will learn that he needs to negotiate a trade, to wait patiently, or to find something else equally fun to play with.

    Friends also provide emotional support, something that is part of the foundation of healthy adulthood. You can't be with your child on the elementary school playground or at the high school dance. Your child's friends will be the ones to stick up for her, to include her in games, and later, to tell her she looks great even if her lousy prom (糟糕的舞会) date wanders off instead of dancing with her.

    Friends also help your children learn. Friends solve problems together, imitate each other, and pass on knowledge.

    Some experts believe that the single biggest predictor of your child's success later in life is her ability to make friends. In fact, they claim it's even more important than IQ and grades.

    This doesn't mean that the kids who are most popular in school do the best later on in life. What matters is not the number of friends a child has but rather the quality of the relationships.

    This is good news for those of us who hate to think that popularity really is the Holy Grail of childhood and adolescence. While it's true that popularity has many advantages, and that many popular kids really are nice people—and not just the best dressed or best looking—it's better to have a few good friends than to have the admiration of the masses.
