    Try this: For an entire day, forget about the clock. Eat when you're hungry and sleep when you're tired. What do you think will happen?

    You may be surprised to find that your day is much like most other days. You'll probably get hungry when you normally eat and tired when you normally sleep. Even though you don't know what time it is, your body does.

    These patterns of daily life are called circadian rhythms, and they are more than just habits. Inside our bodies are several clocklike systems that follow a roughly 24-hour cycle. Throughout the day and night, our internal clocks direct changes in temperature, body chemicals, hunger, sleepiness and more.

    Everyone's rhythms are unique, which is why you might like to stay up late while your sister always wants to go to bed early. But overall, everyone is programmed to feel tired at night and energetic during the day.

    Scientists have known for a long time that the light of day and the dark of night play important roles in setting our internal（内部的） clocks. Now, new discoveries are giving scientists insights into how these clocks work.

    Learning about our body clocks may help scientists understand why problems arise when we act out of step with our circadian rhythms. For example, traveling across time zones can make people wake up in the middle of the night. Regularly staying up late can make kids do worse on tests and quizzes. And working shifts at night leads to higher rates of heart disease, diabetes and obesity.

    “There is a growing sense that when we eat and when we sleep are important parts of how healthy we are,” says Steven Shea, Director of the Sleep Disorders Research Program at Brigham and Women's Hospital in Boston.

    Scientists still aren't sure why the timing of sleep matters so much, Shea says. But research findings suggest that our circadian rhythms are more important than we give them credit for.

    “During the night, we are prepared to sleep,” Shea says. “During the day, we are prepared to eat and move around. If you reverse (颠倒)what you are doing, everything is out of phase. That can have unfavorable consequences.”

    Science has a lot of uses. It can uncover laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation(诱惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal: The Hidden Sources of Love, Character, and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.

    Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren't?

    To answer these questions, Brooks surveys a wide range of disciplines（学科）.Considering this, you might expect the book to be a dry recitation of facts. But Brooks has structured his book in an unorthodox(非常规的), and perhaps unfortunate, way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention. So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.

    On the whole, Brooks's story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong or memorable characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks's attempt to translate his tale into science.

    When you cross over the border from England into Wales, you don't have to show your passport but you do notice a difference immediately. All the road markings and signs are shown in two languages — English and Welsh (威尔士语）. Not all visitors to Britain know that other languages are spoken here. There's the Gaelic (盖尔语) language in Scotland and a few people speak Cornish (康沃尔语）in the southwest of England, but the most widely spoken language in the UK besides English is Welsh.

    Perhaps the first Welsh word you^'ll see on the road into Wales is ARAF. There's a helpful English translation next to it — SLOW. As you can see, Welsh looks quite different from English. It sounds very different, too. Welsh looks and sounds so different from English because it's a Celtic language. Celtic cultures still exist around the edges of the UK — in Wales, Scotland and Northern Ireland and also in parts of France. For hundreds of years, almost everyone in Wales spoke Welsh, but nowadays there are about 600 thousand Welsh speakers — around 20% of the population.

    So is Welsh dying out? Not at all! Nowadays, all school children in Wales study Welsh and many choose to go to an all Welsh-speaking school. You can get public information in Welsh, speak Welsh in court or take a course at university in Welsh. People surf the Internet in Welsh, keep up with friends on Facebook and write blogs in Welsh.

    By the way, ^“Croeso I Gymru!" means “Welcome to Wales!” 一 I hope you'll be able to visit it one day.

    Imagine that you're looking at your company-issued smartphone and you notice an e-mail from Linkedln: “These companies are looking for candidates like you!” You aren't necessarily searching for a job, but you're always open to opportunities, so out of curiosity, you click on the link. A few minutes later your boss appears at your desk. “We've noticed that you're spending more time on Linkedln lately, so I wanted to talk with you about your career and whether you're happy here,” she says. Uh-oh.

     It's an awkward scene. Attrition (损耗) has always been expensive for companies, but in many industries the cost of losing good workers is rising, owing to tight labor markets. Thus companies are making greater efforts to predict which workers are at high risk of leaving ,so that managers can try to stop them. Methods range from electronic monitor to well-designed analyses of employees' social media lives.

     Some of this work may be a reason to let employees to quit. In general, people leave their jobs because they don't like their boss, don't see opportunities for promotion or growth, or are offered a higher pay; these reasons have held steady for years.

    New research conducted by CEB, a Washington-based technology company, looks not just at why workers quit but also at when. “We've learned that what really affects people is their sense of how they're doing compared with other people in their peer group, or with where they thought they would be at a certain point in life, says Brian Kropp, who heads CEB's HR practice. “We've learned to focus on moments that allow people to make these comparisons.”

Technology also provides clues about which star employees might be eyeing the exit. Companies can tell whether employees using work computers or phones are spending time on (or even just opening e-mails from) career websites, and research shows that more firms are paying attention to these things. Large companies have also begun searching for badge swipes (浏览痕迹)—- employees' use of an ID to enter and exit the building or the parking garage—to identify patterns that suggest a worker may be interviewing for a job.

    What can technology do to make your world better?Three young people are starting new businesses to answer that question.

Mateusz Mach

    Eighteen-year-old Mateusz Mach was the youngest person in Poland to receive money from investors to expand his company.He started Five,a mobile messaging application,or app,for deaf people.The app lets deaf people create their own hand signs to communicate with friends.The app now has more than 10,000 deaf users.And Mach thinks there will be about 150,000 more deaf users in the U.S. next year.There are many different sign languages in various parts of the world.Mach will be working with the United Nations in New York.He says,"I love to create.And I think that the creation of things will be my passion to the end of my life."

Zhou says building startups is a difficult process because it could last years."It's only worth it if you find something you truly care about—something you're passionate about.Otherwise,you may just end up crashing."

    George Mtemaharji

    George Mtemahanji was born in the African country of Tanzania and moved with his family to Italy in 2002, where he attended the Technical Institute of Alfredo Ferrari in Maranello.There he learned about renewable energy and began thinking that solar energy would be easier to use in Africa than in Europe.After graduation,he returned to Tanzania in 2014 to start his own solar energy company—Sun Sweet Solar—in partnership with his friend Manuel Rolando.He explains that he could not understand why,in a place with bright sunshine,"more than 90 percent of people had no access to electricity.So when I returned to Italy I spoke with Manuel on the huge electricity demand in Tanzania and to the possibility to open a business there."Sun Sweet Solar found early success in rural areas of Tanzania.Since then,the company has been expanding.He hopes to create jobs and help build his country in the process.He understands the process will take time."But I think we are on the right path."
