The iPhone, the iPad: each of Apple's products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i” --and many other brands are following suit. The BBC's iPlayer--which allows Web users to watch TV programs on the Internet--used the title in 2008. A lovely bear--popular in the US and UK--that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was started last week under the name “i”.

    In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce(电子商务) first came into use.

    Most “I” products are targeted at(针对) young people and considering the major readers of Independent's “I”, it's no surprise that they've selected this fashionable name.

    But it's hard to see what's so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King's College, London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn't have one clear definition(定义),” he says.

    “However, thanks to Apple, the term is now connected with portability (轻便).” adds Thorne.

    Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

    Along with “Google” and “blog”, readers of BBC Magazines voted “I” as one of the top 20 words that have come to define the last decade(十年).

    But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.

    Controlling your food longings and dropping pounds fast is easy: Just eat break-fast. The editors of Eat This, Not That! Carried out researches to determine some best breakfast foods for weight loss.

    Black Beans

    Protein, per 1/2 cup: 7g

    Black beans will not only fill you up for hours but also help slim you down. Wake Forest Baptist Medical Center researchers found that with black beans consumed daily, study participants' fat reduced by 4 percent over two years.

    Peanut Butter

    Protein, per 2 tbsp(汤勺): 7-8g

    While processed peanut butter is filled with sugar and oils, the real stuff is made with just two ingredients: salt and peanuts. The peanut is filled with heart-healthy monounsaturated(单一不饱和的) fats. Nutritionist and personal trainer Kristin Reisinger suggests using the healthy fat in an AM smoothie.

    Almond Butter

    Protein, per 2 tbsp: 7-8 g

    “Almond butter is high in protein, fiber and monounsaturated fats,” says Martha McKittrick, RDN, CDE." Studies have also shown that people who eat nuts are less likely to become overweight than those who avoid them, likely because it helps you feel fuller.” To get the benefits at breakfast, McKittrick suggests spreading some nut butter on the whole grain toast.

    Eggs

    Protein, per two large eggs: 13 g

    “Eggs are an excellent source of protein and other healthy nutrients including fat-burning choline(胆碱),” says McKittrick. Choline, also found in lean(瘦的) meats, seafood and collard greens, attacks the gene mechanism that causes your body to store fat around your liver(肝脏), according to Zero Belly Cookbook. The more eggs you eat, the less egg-shaped you get.

    Robots writing newspapers

    Whether it's robots working as hotel receptionists or artificial intelligence creating poetry, it's becoming more and more common to read about technology doing the jobs of humans.

    And now, it seems that software is even capable of writing news stories –such as the very one you're reading.

    Recently the Press Association (PA), a UK news service, has created a computer program that's capable of creating articles that are almost impossible to tell apart from those written by human journalists.

    Called “robo-journalism”, such software “teaches” itself by analyzing thousands of news stories written by humans. The PA's software is already so advanced that many UK newspapers and websites publish articles created by it.

    According to the Reuters Institute of Journalism, many publishers are using robo-journalism to release interesting information quickly, from election results to official figures on social issues. For example, The Washington Post has its own robo-journalism software, Heliograf. Heliograf “wrote “over 850 articles in 2017, as well as hundreds of social media posts.

    So what does this mean for regular journalists?

    “We're naturally wary about any technology that could replace human beings,” Fredrick Kunkle, a Washington Post reporter, told Wired.

    “But this technology seems to have taken over only some of the work that nobody else wants to do.” “Indeed, it appears that robo-journalism software is designed to help humans, rather than take away their jobs.

    “In the future, Heliograf could do things like search the web to see what people are talking about, check The Washington Post to see if that story is being covered, and, if not, alert(提醒) editors or just write the piece itself.”Wired reporter Joe Keoha wrote.

    However, Joshua Benton at Harvard University's Nieman Journalism Lab believes that while robo-jounalism is undoubtedly going to become more present in newsrooms, nothing can replace traditional human creativity.

“Good journalism is not just a matter of inputs and outputs, it is a craft(技艺) that has developed over decades, “ he told BBC News. “The really difficult part of what professional journalists do—carefully weighing information and presenting balanced , contextualized(全景式的) stories —will be very hard for machines to master.

    There are so many expressions in American English that sound pleasant but are not.

    “Face the music” is a good example. When someone says they have to face the music, it does not mean they are going to a musical performance or concert. To face the music means to accept the unpleasant results of an action.

    Imagine a friend asks you to take care of her beautiful red sports car. She gives you the keys and says, “Thanks so much for watching my car while I'm away. But please do not drive it. It is an extremely fast car and you are not on the insurance (保险).”

    But you do not listen. You want to show off to some friends and pretend the car is yours. So, you drive it around town one night. As bad luck would have it, you lose control of the car and drive it into a stop sign. The damage is severe. When your friend returns you must tell her what you have done and “face the music”.

    The “music” here is the consequence or result of your actions. It could be losing her friendship or paying for repairs to her sports car or both. Whatever the music is, you must face it.

    There are other American expressions that mean the same as “face the music”.

    To “take your medicine” means to accept the results from something bad you have done. And if someone says, “You made your bed. Now lie in it.” He means you created a bad situation and now you will experience the results, or as we say in American spoken English, you must deal with it!

    “Pay the piper” also means the same as “face the music”. But, that expression has its own very interesting beginning. We will talk about that on another Words and Their Stories.

    Artificial Intelligence (AI) is making it possible for companies to monitor workers' behavior in great detail and in real time. 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 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 Bemal 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.

    Running seems easy enough: Just grab a pair of sneakers and put one foot in front of the other, right? Well, anyone who struggled to get through a mile knows it's not quite that simple. We've asked experienced runners to tell us something wrong they did when they started running. The following are some of their answers.

    I got excited and signed up for a half-marathon with a few more experienced runner friends, but I wasn't adequately prepared and didn't train efficiently. I ended up with blisters(水泡) on my feet. I couldn't wear shoes for two days!

    I have always been athletic and I have never been badly injured, but one day I felt a slight pain in my knee. I ignored it for a month until I realized I was having a hard time putting weight on my right leg. I finally went to a doctor. It took four months of weekly physical therapy(治疗) to heal. I shouldn't have done that.

    My biggest mistake was treating running like soccer practice: If I wasn't exhausted by the end of practice, I felt as though I didn't work hard enough. I run all of my runs at 80 percent effort, or the equivalent of what I now call tempo runs (节奏跑). I wasn't warming up to the pace or cooling down effectively.

    I decided to go out for a run during the hottest part of the day. At the time, I told myself that it would be refreshing to sweat a little, but I didn't bring adequate water. I returned feeling completely rundown, dehydrated (脱水的), and exhausted. If you must go out on a run during unfavorable weather, wear proper suits and bring enough water to keep you feeling strong.
