    Love it or hate it, there is no escape from Internet slang(俚语).

    This is especially true among young people in some English-speaking countries such as Australia, the UK and the US. These days, if they haven't caught up with the latest popular Internet slang, chances are that they often feel behind the times.

    Take these posts by The Washington Post for example: “David Bowie dying is totes tradge” and “When Cookie hugged Jamal, it made me totes emosh. ”

    What on earth do these mean? Well, “totes” is a short form of the adverb “totally”. Likewise, “tradge” means “tragic” and “emosh” means “emotional”.

    It seems that, for millennials (those born between the early 1980s and late 1990s), typing in this abbreviated form is not only time-saving but also in.

    Many millennial slang words are formed by what linguists(语言学家) call the practice of  “totesing” —the systematic abbreviation of words, according to a recent article in The Washington Post.

    Some people think that millennial slang affects the English language negatively. However, Melbourne University linguist Rosey Billington doesn't agree.

     “When you are able to use language in a creative way, you show you are linguistically knowledgeable because you know the language rules well enough to use words in a different way.” Billington told News.com.au.

    Her view is supported by two linguists, Lauren Spradlin and Taylor Jones, from the City University of New York and the University of Pennsylvania respectively. The two believe that totes-speak is a highly-organized system that can only be used by speakers who have mastered English pronunciation.

    The ability to break apart syllables(音节) and mix different sounds together is key. “Totesing is about sounds, and it follows the sometimes-complex sound system of English,” Jones told The Washington Post. “Totesing is considered random by some people, but it's not true. Instead, it has strict rules to follow. You need to be very fluent in the English language to be able to understand totes-speak. ”

The healthy adolescent boy or girl likes to do the real things in life,to do the things that matter. He would rather be a plumber's mate and do a real job that requires doing than learn about hydrostatics(流体静力学)sitting at a desk, without understanding what practical use they are going to be. A girl would rather look after the baby than learn about child care. Logically we should learn about things before doing them and that is probably why the experts enforce this in our educational system.But it is not the natural way—nor, in my view, the best way. The adolescent wants to do things first for only then does the appreciate the problems involved and want to learn more about them.

    They do these things better in primitive life,for there at puberty(青春期) the boy joins his father in making canoes,patching huts,going out fishing or hunting.He is serving his apprenticeship in the actual accomplishments of life.It is not surprising that anthropologists(人类学家) find that the adolescents of primitive communities do not suffer from the same neurotic(神经质的) “difficulties” as those of civilized life.This is not,as some assume,because they are permitted more sexual freedom,but because they are given more natural outlets for their native interests and powers and are allowed to grow up freely into a full life of responsibility in the community.

    In the 19th century this was recognized in the apprenticeship system,which allowed the boy to go out with the master carpenter,or ploughman,to engage in the actual work of carpentry or roof-mending,and so to learn his trade.In some agricultural colleges at the present time young men have to do a year's work on a farm before their theoretical training at college.The great advantage of this system is that it lets the apprentice see the practical problems before he sets to work learning how to solve them,and he can therefore take a more intelligent interest in his theoretical work.

    Since more knowledge of more things is now required in order to cope with the adult world, the period of growing-up to independence takes much longer than it did in more primitive community,and the responsibility for such education,which formerly was in the hands of the parents,is now necessarily undertaken by experts at school. But that should not make us lose sight of the basic principle, namely the need and the desire of the adolescent to engage responsibly in the real pursuits of life and then to learn how—to learn through responsibility, not to learn before responsibility.

    When I was ten years old I went to the USA to visit some family friends. I noticed something funny about the way everyone spoke English.

    One moment! I remember very clearly was at the beginning of the holiday, when my friend asked me if I wanted to order “French fries”. I couldn't imagine what they were. She was amazed that I had never tried them and she ordered a portion for us to share. When the waiter brought us some chips, I asked her where the French fries were. She pointed at the plate of chips! Later that week she said she was going to buy some “chips” from the supermarket. She came out with a packet of crisps（薯片）! How come?

    During that holiday we were also offered “biscuits” with our lunch. This was a very strange idea to me, because in England biscuits are sweet. I later realized that “biscuits” in America are salty snacks. What we call “biscuits', they call “cookies”.

    I was also embarrassed when a stranger told me she liked my “pants”. I wondered how she could see them! My mum then told me that they call “pants” what we call “trousers”, the outer clothing that you wear on your legs instead of inside clothing!

    I was disgusted when I saw an “eggplant” pizza on the menu in a restaurant. But I was puzzled how eggs can grow on plants. My dad ordered this pizza and it was covered in aubergines（茄子）. “They call aubergines 'eggplant' in America!” he told me.

    I think part of the excitement of learning a language is learning about the differences that exist in how it is spoken in different places.

    Melinda Skaar wasn't expecting any phone calls. Skaar was working late in her office at the First Internet bank of California. By 10:45 that night she was almost ready to go home when the phone rang. Picking it up, she heard a guard shouting, "There is a fire! Get out of there." Skaar didn't panic. She figured that it was just a small fire. Her office building was huge. There were 62 floors and her desk was on the 37th floor. Skaar called out to office mate Stephen Oksas, who also stayed late to work. But when they got out to the hallway, they were met by a cloud of black smoke. Rushing back, Skaar shut the door and filled the space at the bottom of the door with her jacket to keep the smoke out.

    Then they called 911. Before they could call their families, however, the line went dead. That meant that they were completely cut off from the outside world. All they could do was wait and hope someone would come to rescue them.

    Minutes ticked by. Smoke began to float into the office. Soon it became hard for them to breathe. Looking around, Skaar noticed a small workroom. It seemed to have cleaner air. So they crowded there. That helped for a while, but in time even the workroom was filled with deadly smoke. Hopeless, they tried to break the windows, but the glass was not breakable. Everything they threw at it just bounced back. Defeated, they struggled back to the workroom. They felt weak and dizzy. Soon Skaar found Oksas had passed out.

    As Skaar and Oksas lay near death, rescuers were rushing to find them. At last, at about 4 a.m., firefighters found them.

    Skaar and Oksas knew they were lucky to be alive. Sunday is my birthday, Skaar told a reporter. She would be turning 29, but she knew she had already got the best present possible—the gift of life.

    Artificial intelligence（AI）is making it possible for companies to monitor workers' behavior in great detail and in real－time（实时的）. Start to slack off（懈怠）and AI could talk to your boss.

    One company offering such services is London－based start－up Status Today. Its AI platform relies on a regular supply of employee data, including everything from the files you access to when you use a key card.

    From this, it builds a picture of how employees normally function and signals any unusual performance. The idea is to spot when someone might become a security risk by doing something different from their usual behavioral patterns. “All of this gives us a fingerprint of a user, so if we think the fingerprint doesn't match, we raise a warning, ”says Mircea Dumitrescu, the company's chief technology officer.

    The system also aims to catch employee actions that could accidentally cause a security breach（漏洞）, like opening malware（恶意软件）. “We're not monitoring if your computer has a virus。”says Dumitrescu. “We're monitoring human behaviors. ”

    But catching the security breach means monitoring everyone, and the AI can also be used to track employee productivity. “It seems like they are just using the reputation of AI to give an air of lawfulness to old－fashioned workplace surveillance（监视）, ”says Javier Ruiz Diaz of digital campaigning organization the Open Rights Group. “You have a right to privacy and you shouldn't be expected to give that up at work. ”

    Exactly how companies use the system will be up to them, but it's hard to shake the picture of an AI constantly looking over employees' shoulders. “It will bother people, and that could be counterproductive if it affects their behavior, ”says Paul Bernal at the University of East Anglia.

Phil Legg at the University of the West of England says it will never catch every security risk. “If people know they're being monitored, they can change their behavior, ”he says.

    While we all try to find happiness, sometimes we still end up feeling low. While most people can control this feeling, low moods can stay with some, leading to depression. About 322 million people suffered from depression in 2015, according to a report by the World Health Organization in February. This is more than 4 percent of the world's population.

    Depression is described by the WHO as a mental disorder. It has several symptoms including sadness, loss of interest and feelings of low self-worth. In severe cases, depression may even lead to suicide.

    The number of people living with depression is increasing. The WHO reported a rise of 18.4 percent between 2005 and 2015. Young people are a group known to suffer with depression. “The pressures on today's youth are like no other generation, perhaps," Dan Chisholm, an official of WHO, told Reuters.

    In China, depression among young people is on the rise, Zhu Zhuohong, a psychology professor with the Chinese Academy of Sciences, told Xinhua News Agency. Competition to outperform others, especially in education, can cause a lot of pressure for Chinese youth.

    Almost 1.2 million Chinese people aged 15 to 24 suffer from depression, according to a report released by British science journal The Lancet in May.

    Luckily, more and more efforts are being made to deal with this problem. This year's World Health Day, held on April 7, will focus on depression. The day will highlight the “Depression: let's talk" campaign. The campaign aims to make sure that people with depression both seek and get help.
