    Your smartphone(智能手机) can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little device（设备）of yours – it might also spread disease.

    “People are just as likely to get sick from their phones as from handles of the bathroom,” Jeffrey Cain, the president of the American Academy of Family Physicians, told The Wall Street Journal.

    This may be hard to believe, but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms(大肠菌), a kind of bacteria found in excrement(粪便)，with about 2,700 to 4,200 units of the bacteria on each phone. In drinking water, the healthy limit is less than 1 unit per 100 ml of water. This bacteria can cause flu, pinkeye（红眼病）and diarrhea(腹泻).

    Although computers, keys and pens all carry germs(细菌), our smartphones get far dirtier. They touch a lot of stuff, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn't played Angry Birds of Fruit Ninja while sitting on the toilet?

    “Some things that we think are personal are actually more public than we imagine,” Cain said.

    What's even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don't think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease（油脂）, an environment that germs really like.

    Compared to traditional keypads（键盘）, touch screens transmit（传播）germs more easily to hands. According to Time magazine's website, an expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk.

    So how do you keep your smartphone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone's surface: wash your hands regularly.

    The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before. But just as in face to face communication, there are some rules of behavior that should be followed when on line.

    Imagine how you'd feel if you were in the other person's shoes. For anything you're about to send，ask yourself, ＂Would I say this to the person's face?＂ If the answer is no, rewrite and reread.

     If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

    Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended. It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.

    A popular saying goes, “Sticks and stones may break my bones, but words will never hurt me.” However, that's not really true. Words have the power to build us up or tear us down. It doesn't matter if the words come from someone else or ourselves — the positive and negative effects are just as lasting.

    We all talk to ourselves sometimes. We're usually too embarrassed to admit it, though. In fact, we really shouldn't be because more and more experts believe talking to ourselves out loud is a healthy habit.

    This “self-talk” helps us motivate ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in saying “Good job!”

    Often, words come out of our mouths without us thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clerk will probably respond in a similar manner. Or harsh (刻薄的) and critical language will most likely cause the clerk to be defensive.

    Words possess power because of their lasting effects. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it true? Is it loving? Is it needed? If what we want to say doesn't pass this test, then it's better left unsaid.

    Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem (自尊) and motivate others to do their best. Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.

    Best friends may be priceless but the cost of keeping the relationship alive is £23,870.

    According to a study, a BFF (best friends forever) does not come cheap with devoted friends spending £4,679 on birthday presents alone over a lifetime. And while it costs nothing to be a shoulder to cry on, big-hearted Britons go the extra mile and spend £168 on pick-me-ups(提神物品) to get their mate through a rocky patch (艰难时刻)like the breakup of a relationship.

    There's a further £242 spent on presents to show how much they mean from gifts bought on holiday to treats for no reason. And distance does not break up a close friendship as BFFs spend a whopping(巨大的) £18,000 on travel to see each other despite being miles apart because of university, jobs and marriage.

    The study by cashback site TopCashBack found on average BEFs who marry can expect £431 spent on them and a further £283 on gifts when they have children. And they can rely on their pals to help out when they move houses as they will obtain £127 worth of housewarming presents and takeaways(a kind of food).

    The survey based on a friendship lasting 40 years found more than eight in ten adults with a BFF felt their friendships were worth every penny.

    TopCashback spokesperson Natasha Smith said: “Those friendships which stand the test of time are often the most important in our lives. However, they come at a cost. From train tickets once a month to flights and a new dress for a wedding on the Italian coast, the price paid for having a best mate can soon add up. But when we asked people to compare their friendship with the financial investment(投资), only 14% thought their friendship was equal to their investment with the vast majority thinking it was worth more."

    A new generation addiction(上瘾) is quickly spreading all over the world. Weboholism（网瘾）, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.

    Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. Such behavior has seriously affected teenagers and college students. They are likely to log(写日志) on computers and spend long hours at different websites.

    They become hooked(着迷) on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don't concentrate on homework, so this addiction influences their grades and success at school. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.

    They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.

    Because of the change in their behavior, they begin to isolate themselves from society and live with their virtual(虚拟的) friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real life friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect all the world.

The practice of students endlessly copying letters and sentences from a blackboard is a thing of the past. With the coming of new technologies like computers and smartphone, writing by hand has become something of nostalgic (怀旧的)skill. However, while today's educators are using more and more technology in their teaching, many believe basic handwriting skills are still necessary for students to be successful—both in school and in life.

    Virginia Berninger, professor of educational psychology at the University of Washington, says it's important to continue teaching handwriting and help children acquire the skill of writing by hand.

Berninger and her colleagues conducted a study that looked at the ability of students to complete various writing tasks—both on a computer and by hand. The study, published in 2009, found that when writing with a pen and paper, participants wrote longer essays and more complete sentences and had a faster word production rate.

    In a more recent study, Berninger looked at what role spelling plays in a student's writing skills and found that how well children spell is tied to know well they can write. “Spelling makes some of the thinking parts of the brain active which helps us access our vocabulary, word meaning and concepts. It is allowing our written language to connect with ideas.” Berninger said.

    Spelling helps students translate ideas into words in their mind first and then to transcribe(转换) “those words in the mind written symbols on paper or keyboard and screen,” the study said. Seeing the words in the “mind's eye” helps children not only to turn their ideas into words, says Berninger, but also to spot(发现) spelling mistakes when they write the words down and to correct then over time.

     “In our computer age, some people believe that we don't have to teach spelling because we have spell checks,” she said. “But until a child has a functional spelling ability of about a fifth grade level, they won't have the knowledge to choose the correct spelling among the options given by the computer.”

    Women make better drivers than men for many reasons. Why is that, do you suppose? Wouldn't you think that competing at who has better driving abilities is pointless? If you ask me, I'd like to say, men know that women are better drivers but do not have the courage to admit the truth—women are queens of the road.

    Unlike men, women stop for directions when they have no idea as to where they are going. We don't drive around for hours pointlessly wasting a tank of gas only to find ourselves heading in the wrong direction. Have you ever in a car with a man who is lost? He tells you to shut up when you begin to open your mouth. And every five minutes or so he takes a tum going forty-five miles per hour only to find out he's made another wrong turn.

    Speeding is what men do best on the road. Traffic is not a race. There is a reason why men get more speeding tickets than women. Not because we trick to get out of tickets but only because we don't get pulled over as frequently. We don't speed. We have more intelligence than senselessly to put our own lives as well as the lives of others in danger.

    My largest issue with male drivers is how a majority of them drive with one hand on the wheel and the other hand doing only God knows what. The seat is backed as far as possible, and they're totally lost into loud music beyond a necessary level. You don't ever see women driving like that.

    I feel that the above evidence more than proves my points that women are not only better drivers but also safer drivers than men. We women rule the road. Oh, and men, if you want to continue criticizing women for being bad drivers, bring it on. We know you lack confidence, or else you wouldn't be wasting your valuable time making jokes about the ones you may choose to spend the rest of your days with.

    To err is human. To blame the other guy is even more human.

    Common sense is not all that common.

    Why tell the truth when you can come up with a good excuse?

    These three popular sentences are meant to be jokes, and yet they tell us a lot about human nature .To err, or to make mistakes, is indeed a part of being human, but it seems that most people don't want to accept the responsibility for the problem. Perhaps it is the natural thing to do .The original quote about human nature went like this: " To err is human, to forgive, divine(神圣的).".This saying mirrors an ideal people should be forgiving of others' mistakes. Instead, we tend to do the opposite –find someone else to pass the blame on to. However, taking responsibility for something that went wrong is a making of great maturity.

    Common sense is what we call clear thought. Having common sense means having a good general plan that will make things work well, and it also means staying with the plan. Common sense tells you that you take an umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine. Common sense does not seem to be common for large organizations, because there are so many things going on that one person cannot be in charge of everything. People say that in a large company, "the right hand does not know what the left hand is doing."

    And what is wrong with a society that thinks that making up a good excuse is like creating a work of art? One of the common problems with making excuses is that people, especially young people, get the idea that it's okay not to be totally honest all the time. There is a corollary(直接推论)to that: if good excuse is "good" even if it isn't honest, then where is the place of the truth?

    A university in Nanjing, Jiangsu province, has installed facial recognition systems in classrooms to monitor students' behavior, sparking a heated debate online. China Pharmaceutical University recently installed the systems in two pilot classrooms as well as school gates, dormitory entrances, the library and laboratory buildings.

    Xu Jianzhen, director of the university's library and information center, told TbePaper.cn that the systems will help teachers check student attendance and monitor behavior during the lectures. "In the past, some students just checked their attendance and ditched the class or asked other students to check the attendance for them. Now with facial recognition, that would no longer be a problem," he said. "The moment you enter the classroom, the camera will monitor you all the way through and can tell how long you lower your head, whether you're playing with a smart phone, whether you're dozing off or reading other books," he added.

    The news has raised wide debate on Chinese social media, with many questioning if the cameras will violate students' privacy. A Sina Weibo user said: "I oppose such methods, and it is not clear whether the systems are developed by the school itself or by third parties. If it is the latter, is there any regulation of security? Where will the information be sent and stored?"

    Gan Xiangsi, a senior student from the university, said she welcomed the systems being applied in dormitories and libraries as this can help prevent personal belongings being stolen，but it is not necessary to use such technology in the classroom. "If the teacher teaches well，the students will be interested," she said. "On the contrary, this kind of monitoring will make everyone feel resistant."

    China Pharmaceutical University is not the first university to use facial recognition technology on campus. Many universities across the country have installed cameras at campus entrances to ensure safety. But many are also hesitant when it comes to applying such technology in classrooms.

    "This issue has been debated for quite a long time," Chu Zhaohui, a senior researcher at the National Institute of Education Sciences, told China National Radio. According to Chu, teachers and students who are under observation might not behave as they normally would since they know they are being watched. "Cameras should not be installed in classrooms merely for effective teaching purposes," Chu said, as teachers are also being observed. He agreed that "students' privacy needs to be protected". He also said that not putting classrooms under control is an important principle. "If you don't follow this principle, students will falsify and disguise their state of listening，and teachers may also not perform as well. Then real teaching will not occur," he added.

    Pink has never been one of the favourite colours of the fashion industry, as it's often seen as silly and not cool enough. But this spring, it's having its moment in the spotlight, all thanks to the fact that the colour is no longer all about being girly and sweet. Instead, pink is taking on a new meaning of independence and power.

    This shift happened last month during the Women's March. Tens of thousands of women filled the streets of major cities in the US and in countries all around the world to protest(抗议)against the disrespect to women. What was unusual about the protests is that a lot of people taking part were wearing pink hats, making the streets appear like a "sea of pink". Even though the hats were without any slogan (标语),their pink colour is thought to have sent out a message that is louder than any words. "We women have power and we're not going to sit down and shut up," Aileen Gildea, one of the protesters in the US, told The Boston Globe.

    Now young people are changing their attitudes to pink. They are no longer trying to escape pink, but give new meanings to it instead.

    "Women who came before us had to get away from the symbols used to make women seem less capable. Younger women don't have that reaction. They're more interested in breaking and rebuilding those symbols," Audrey Gelman, a businesswoman in the US, told The Wall Street Journal.

    So sometimes it's not the thing itself that needs to be changed, but the way we look at it. And in the case of pink, what used to be seen as silly may be turned into something really serious.

    Leaders in the aviation (航空) industry plan to launch a campaign (发起运动) that they hope will work against what they call a "Flight Shaming Movement" (FSM). They say FSM has weakened people's demand for air travel in Europe. Some travelers there are increasingly concerned about the effects of flying on the environment. Activists have been calling for greater action against climate change. That includes avoiding air travel.

    FSM has affected air travel demand in many European countries, including Britain, France and Germany. The campaign will try to explain to the public how the industry is reducing its effect on the environment. Juniac, head of IATA, said FSM gave off "misleading information".

    The International Air Transport Association (IATA) is organizing the plan through the Air Transport Action Group, a group of aviation industry organizations and companies. Juniac didn't say when the campaign would start, but noted that details would be available to airports and airlines.

    Commercial flying is estimated to cause about 2.5% of worldwide carbon emissions (释放). However, that number could rise as worldwide air travel increases.

    The aviation industry says it has already cut carbon emissions by one-half since 1990. The improvements are mainly the result of aircraft that use fuel more effectively. The industry plans to cut emissions further by 2050. It has a goal of stopping the growth of carbon emissions by 2020.

    Airlines also have warned of the harmful effects of FSM. Some have criticized the industry for failing to explain itself. Tim Clark, president of the Airline Emirates, said that improvements in technology have reduced the environmental effects of passenger airplanes.

    We all, at one time or another, have pretended to be a rock star, singing and dancing along to our favorite song. Most of us have done this in the privacy of our own room when we were kids and as adults, in the privacy of our homes. Me? I love to do that when I drive! I turn on the radio, find a song that I can sing along too and pretty soon my arms are in the air and I am moving along to the rhythm. Most of the time, I do this on my way to work.

    Yes, that is true. I will be in my nice work clothes, jamming while driving or stopped at a traffic light. I get weird looks from some people and others laugh. Personally, I love to get lost in the rhythm of a song which leads me to share with you the importance of being silly!

    The definition for the word silly, according to the dictionary is: stupid, foolish and nonsensical. I know many people do not want to look foolish. So they walk around all serious, which in all honesty, is foolish!

    No one is perfect, I repeat: no one is perfect. I don't care how educated, how thin, how beautiful, how simple, how frugal, how rich, and so on… No one is perfect! So why pretend to be something you are not?

    Life is so short… You never know when this beautiful journey will be over, so why waste a single second on being so full of rigidity(呆板)? Here is a quote by Souza, that I think says it all and is a great recipe for life:

    Dance as though no one is watching you,

    Love as though you have never been hurt before,

    Sing as though no one can hear you,

    Live as though heaven is on earth."

    When we were kids, we had no idea of what limitations were and we had no care in the world so we could do things without worrying about how we appeared to others. However, as we grew up, we lost that childlike innocence.

    So don't lose the child that still lives within you. The next time you feel down, go turn on your favorite song, and sing and dance along like there is no tomorrow. Or watch something that makes you laugh. Laughter is the best medicine to whatever ails you and nothing is better than laughing so hard that your tummy hurts. Trust me, you will feel a whole lot better, and who doesn't want to feel good?

    You signed up for soccer, and played every game of the season. Sure, you're not the best player on the team, but most days you gave it your all. Do you deserve a trophy (奖杯)?

    If the decision is up to Carol Dweck, the answer would likely be no. She's a psychology professor at Stanford University, California. She says a player doesn't have to be the best to get a trophy. But those who receive an award should have to work for it. She suggests trophies go to the most improved player, or the one who contributed most to the team spirit, as well as to those who play the best.

    "The trophy has to stand for something," Dweck told TFK. "If we give a trophy to everyone, then the award has no value." Dweck argues that giving kids trophies for particular reasons, such as improving in a sport, teaches kids that adults value hard work and trying our best.

    Others say that there's no harm in giving awards to all kids who play a sport, regardless of how they played or whether or not they improved.

    "I think we should encourage kids' participation in sports," says Kenneth Barish, a psychology professor at Weill Cornell Medical College, in New York City. "A trophy is one way to encourage kids' efforts."

    Barish argues that when we single out only the best or even the most improved players with a trophy, we are teaching kids the wrong lesson. We are sending the message that winning is everything. "Winning is only part of the equation (等式)," Barish told TFK. "Playing sports also teaches kids about teamwork and the importance of exercise."

    There will be plenty of opportunities for kids to learn about competition as they get older, says Barish. They'll soon realize that only one soccer team wins the World Cup and only one football team wins the Super Bowl. For now, he thinks there's nothing wrong with letting all kids who play a sport feel like winners. That means trophies for everyone.

    On August 29th, as Hurricane Dorian tracked towards America's east coast, Elon Musk, the boss of Tesla, an electric-car maker, announced that some of his customers in the storm's path would find that their cars had suddenly developed the ability to drive farther on a single battery charge. Like many modern vehicles, Mr. Musk's products are best thought of as internet-connected computers on wheels. The cheaper models in Tesla's line-up have parts of their batteries disabled by the car's software in order to limit their range. At the tap of a keyboard in Palo Alto, the firm was able to remove those restrictions and give drivers temporary access to the full power of their batteries.

    Mr. Musk's computerized cars are just one example of a much broader trend. As computers and connectivity become cheaper, it makes sense to bake them into more and more things that are not, in themselves, computers, creating an "internet of things".

    Such a world will bring many benefits. Consumers will get convenience, and products that can do things non-computerized versions cannot. Businesses will get efficiency, as information about the physical world that used to be uncertain becomes concrete and analyzable.

    In the long term, though, the most obvious effects will be in how the world works. Ever more companies will become tech companies; the internet will become everywhere. As a result, a series of unresolved arguments will spill over from the virtual world into the real one.

    Start with ownership. As Mr. Musk showed, the internet gives firms the ability to stay connected to their products even after they have been sold, transforming them into something closer to services than goods. That has already made the traditional ideas of ownership unclear. When Microsoft closed its ebook store in July, for instance, its customers lost the ability to read titles they had bought(the firm offered refunds). That shifts the balance of power from the customer to the seller.

    Virtual business models will jar in the physical world. Tech firms are generally happy to move fast and break things. But you cannot release the beta version(测试版)of a fridge. Apple, a smartphonemaker, provides updates for its phones for only five years or so after their release; users of Android smartphones are lucky to get two. But goods such as washing machines or industrial machinery can have lifespans of a decade or more. Firms will need to work out how to support complicated computerised devices long after their original programmers have moved on.

    Data will be another flashpoint. For much of the internet the business model is to offer "free" services that are paid for with valuable user data, collected with consent(同意)that is half-informed at best. In the virtual world, arguments about what should be tracked, and who owns the resulting data, can seem airy and theoretical. In the real one, they will feel more urgent.

    Predicting the consequences of any technology is hard—especially one as universal as computing. The emergence of the consumer internet, 25 years ago, was met with starry-eyed optimism. These days the internet's faults dominate the headlines. But the people have the advantage of having lived through the first internet revolution—which should give them some idea of what to expect.

In the summer of 2016, I gave a talk at a small conference in northern Virginia. I began by admitting that I'd never had a social-media account; I then outlined arguments for why other people should consider removing social media from their lives. The event organizers uploaded the video of my talk to YouTube. Then it was shared repeatedly on Facebook and Instagram and, eventually, viewed more than five million times. I was both pleased and annoyed by the fact that my anti-social-media talk had found such a large audience on social media.

I think of this event as typical of the conflicted relationships many of us have with Facebook, Instagram, and other social-media platforms. On the one hand, we've grown wary of the so-called attention economy, which, in the name of corporate profits, destroys social life gradually and offends privacy. But we also benefit from social media and hesitate to break away from it completely. Not long ago, I met a partner at a large law firm in Washington, D.C., who told me that she keeps Instagram on her phone because she misses her kids when she travels; looking through pictures of them makes her feel better.

In recent months, some of the biggest social-media companies, Facebook and Twitter, in particular, have promised various reforms. In March, Mark Zuckerberg announced a plan to move his platform toward private communication protected by end-to-end encryption (端对端加密); later that month, he put forward the establishment of a third-party group to set standards for acceptable content.

All of these approaches assume that the reformation of social media will be a complex, lengthy, and gradual process. But not everyone sees it that way. Alongside these official responses, a loose collective of developers that calls itself the IndieWeb has been creating another alternative. They are developing their own social-media platforms, which they say will preserve what's good about social media while getting rid of what's bad. They hope to rebuild social media according to principles that are less corporate and more humane.

In some islands north of Scotland, if head lice (头虱) left their host, he became sick and feverish. Therefore, sick people had lice put in their hair intentionally. There was a method in their madness: As soon as the lice had settled in again, the patient improved. The story explains the confusion of cause and effect. If the lice leave the sick host, it is because he has a fever and they simply get hot feet, and when the fever breaks, they return. Such false causality (假因果关系) misleads us every day.

Consider the headline: "Fact: Women Who Use Shampoo XYZ Every Day Have Stronger Hair." It says very little -- least of all, that the shampoo makes your hair stronger. It might simply be the other way round: women with strong hair tend to use Shampoo XYZ -- and perhaps that's because it says "especially for thick hair" on the bottle.

Another example: Scientists found that long periods in the hospital did harm to patients. But, clearly, patients who are dismissed immediately are healthier than those who must stay on for treatment.

Recently I read that students get better grades at school if their homes contain many books. This study was surely a shot in the arm for booksellers, but it was also false causality. This simple truth is that educated parents tend to value their children's education more than uneducated ones do, and they often have more books at home. In short, a dust-covered copy War and Peace alone isn't going to influence anyone's grades; what counts is parents' education levels, as well as their genes.

There was also the supposed relationship between the birth rate and the numbers of stork (鹳) pairs in Germany. Both were in decline, and if you plot (描绘) them on a graph (曲线图)，the two lines of development from 1965 to 1987 appeared almost the same. Does this mean the storks actually bring babies? Obviously not. This was a purely accidental connection.

In conclusion: Connection is not causality. Take a closer look at linked events: Sometimes what is presented as the cause turns out to be the effect, or just the other way round, and sometimes there is no link at all - just like with storks and babies.

Recently I read Nineteen Eighty-Four, a novel by George Orwell set in a state where even the language they use is controlled. Adjectives are forbidden and instead they use phrases such as 'ungood', 'plus good' and 'double plus good' to express emotions. As I first read this I thought how impossible it would be in our society to have such vocabulary. However, the more I thought about it, the more I realised in its own way it's already happening. I type messages to my friends and alongside each is the emoji. I often use them to emphasise something, or to not seem too serious, or because this specific GIF conveys my emotions much better than I ever could using just words. And I wonder, with our excessive use of emojis, are we losing the beauty and diversity of our vocabulary?

English has the largest vocabulary in the world, with over one million words, but who's to say what it'll be like in the future? Perhaps we will have a shorter language, full of saying 'cry face' if something sad happens or using abbreviations (缩写) like LOL (laugh out loud) or BRB (be right back) instead of saying the full phrase. So does this mean our vocabulary will shrink? Is it the start of an exciting new era? Will they look back on us in the future and say this is where it all began – the new language? Or is this a classic case of the older generations saying, 'Things weren't like that when I was younger. We didn't use emoticons to show our emotions'?

Yet when you look back over time, the power of image has always been there. Even in the prehistoric era they used imagery to communicate, and what's even more incredible is that we are able to analyse those drawings and understand the meaning of them thousands of years later. Pictures have the ability to transcend time and language. Images, be it cave paintings or emojis, allow us to convey a message that's not restrictive but rather universal.

Growing up, we are constantly reminded that young people are heavily affected by technology. We are the "antisocial club", those who prefer to text our friends in the same room rather than make eye contact with them. And even though never-ending studies reveal to us the extent of our social media addiction, we should at least consider that it's not only our young people's problem any more.

There's the rise of the Instagram mums, who like to post an abundance of cute baby pictures, share their mom feelings along the way and show their wonderful lifestyles. They are the so-called "Facebook mum generation", a growing group of parents that like to overshare.

While all of this might be fine, and even a little humorous, new research suggests that parents' technology addiction is negatively affecting their children's behavior. According to the study, 40% of mothers and 32% of fathers have admitted having some sort of phone addiction. This has led to a significant fall in verbal interactions within families and even a decline in mothers' encouraging their children.

There is no denying that I get annoyed when receiving the words "I'll be with you soon" from a parent, when all I want to do is ask one question. But, at the same time, every day leaving the room to wait until my father is finished with his "serious business" (Farmville), has now become the norm. Whether you want to escape your disturbing children for a bit, or want to stay up late flicking through Twitter, know that wanting to do all of these is normal. We, your children, know how addictive it can be and how difficult it is to switch off. But before telling us to put our phones away at the table or even worse, listing statistics of how damaging social media can be for us, maybe lead by example, considering how much time you spend on the phone and how this is impacting your children and your relationship with us. Maybe in this way we can work on our addiction together.

As a CEO of a startup, you get used to hearing" no". You also face an endless continuation of what feels like shocking crises, like nearly running out of cash, losing a key customer, discovering a widespread product failure, or having to shut down operations because of a global pandemic. But it turns out that these disasters can actually be good for you. In fact, I'm not sure whether you can innovate without them. Here's what all our crises have taught me.

It's good to be uncomfortable. We once had a key customer request-a battery capability that we'd never developed before. The customer made it clear that if we couldn't develop this capability, they'd be less confident in our product. We wrestled with the risks, not least of which was the potential embarrassment if we couldn't meet the customer's needs. We knew we'd face many technical problems if we tried to go into operation. Yet we decided to try to satisfy the customer, even if it wasn't obvious at first how we could get it done. A few weeks later we delivered something beyond what the customer had asked for, and we've since grown this capability into a powerful sales tool and potential revenue stream-not to mention it strengthened our relationship with the customer.

Short-term failure is good. A few years ago, our company began to expand our manufacturing output in response to a customer's need. In the process we discovered something unusual we hadn't seen during smaller-scale production. Our team dived into failure analysis, and we finally put the problem down to a single material within the battery. We'd used this material for years, but now we needed a replacement. Once we made that change, the battery quality and reliability greatly improved.

It's okay to show weakness. One of my hardest days as CEO was the day when I found out I was pregnant. We were in the middle of raising a funding round, and I had been traveling nonstop for a year. Until that day, I had assumed that my role as CEO was to display strength and confidence. With the mounting pressure I was harder on myself than I needed to be, and now I had the added stress of being pregnant. I decided to acknowledge to my team that I was breaking down. They united together and found ways to operate more smoothly and communicate more effectively, supporting me to focus my time on most pressing goals. This gave me not only the space to plan for the company's future, but also to prepare for my own new normal: leading while becoming a first-time mother.
