My father had returned from his business visit to London when I came in, rather late, to supper. I could tell at once that he and my mother had been discussing something. In that half-playful, half-serious way I knew so well, he said, "How would you like to go to Eton?"

    "You bet," I cried quickly catching the joke. Everyone knew it was the most expensive, the most famous of schools. You had to be entered at birth, if not before. Besides, even at 12 or 13, I understood my father. He disliked any form of showing off. He always knew his proper station in life, which was in the middle of the middle class, our house was medium-sized; he had avoided joining Royal Liverpool Golf Club and went to a smaller one instead; though once he had got a second-hand Rolls-Royce at a remarkably low price, he felt embarrassed driving it, and quickly changed it for an Austin 1100.

    This could only be his delightful way of telling me that the whole boarding school idea was to be dropped. Alas! I should also have remembered that he had a liking for being different from everyone else, if it did not conflict(冲突) with his fear of drawing attention to himself.

    It seemed that he had happened to be talking to Graham Brown of the London office, a very nice fellow, and Graham had a friend who had just entered his boy at the school, and while he was in that part of the world he thought he might just as well phone them. I remember my eyes stinging (刺痛) and my hands shaking with the puzzlement of my feelings. There was excitement, at the heart of great sadness.

"Oh, he doesn't want to go away," said my mother, "You shouldn't go on like this." "It's up to him," said my father. "He can make up his own mind."

    Four years ago, Chris Nagele did what many other technology CEO have done before—he moved his team into an open concept office.

    His staff had been working from home, but he wanted everyone to be together. It quickly became clear, though, that Nagele had made a huge mistake. Everyone was distracted, productivity(生产率) suffered and the nine employees were unhappy, not to mention Nagele himself.

    In April 2015, about three years after moving into the open office, Nagele moved the company into a 10,000-square-foot office where everyone now has their own space — complete with closing doors.

    Numerous companies have accepted the open office. But we're 15% less productive, we have great trouble concentrating.

    Since moving, Nagele himself has heard from others in technology who say they long for the closed office lifestyle. It's unlikely that the open office concept will go away anytime soon, but some companies are following Nagele's example and making a return to private spaces.

    There's one big reason we'd all love a space with four walls and a door that shuts: focus. The truth is, we can't multitask(多任务化) and small distractions can cause us to lose focus for upwards of 20 minutes.

    What's more, certain open spaces can negatively impact our memory. We retain(保留) more information when we sit in one spot, says Sally Augustin, an environmental and design psychologist in La Grange Park, Illinois. It's not so obvious to us each day, but we offload(卸下) memories — often little details — into our surroundings, she says.

    Beside the cheaper cost, one main argument for the open workspace is that it increases teamwork. However, it's well documented(记载) that we rarely brainstorm brilliant ideas when we're just talk casually in a crowd.

    What would you say if we told you that you could learn to speak a new language in only 7 days? Pretty unbelievable right? But how could it be? To find out,we spoke to David-one of our brave Babbel learners—to see how the Babbel app successfully got him speaking Norwegian(挪威语)in just one week.

How much time did you learn each day?

    I didn't need to give my entire life over to learning Norwegian. Each Babbel lesson takes only 15 minutes, and I set myself the achievable aim of finishing three Babbel lessons daily.This took only 45minutes each day.

How did the Babbel app help you learn so quickly?

    The Babbel app has a course plan for beginners that taught me how to make sentences in Norwegian within the first few days. Then I was able to personalize my learning by selecting single-topic lessons on eating, drinking, music, culture, traveling and so on. This allowed me to quickly enlarge my vocabulary!

    This way of learning kept me highly active,and made sure I wasn't bored to tears with grammar practice that we all remember from school!

    “After 7 days I was able to introduce myself in Norwegian,talk about my hobbies and interests, and most importantly,communicating with a native Norwegian speaker in a real conversation and I could even play a joke or two!”

    Would you introduce this app to others?

    Certainly! Babbel has 14 languages to choose from so if you're thinking about brushing up on your German for a business trip, or learning a bit of Portuguese (葡萄牙语) for next year's summer vacation, you'll be happy to hear that you only need an app, 7 days of learning to get you conversational.

    There is an old Chinese proverb that states "One Generation plants the trees; another gets the shade," and this is how it should be with mothers and daughters. The relationship between a mother and daughter is sometimes confusing. If close, the relationship can be similar to friendship. However, the mother and daughter relationship has unique characteristics that distinguish it from a friendship. These characteristics include a hierarchy (等级) of responsibility and unconditional love, which preclude mothers and daughters from being best friends.

    Marina, 27 years old, says, "I love spending time with my mom, but I wouldn't consider her my best friend. Best friends don't pay for your wedding. Best friends don't remind you how they carried you in their body and gave you life! Best friends don't tell you how wise they are because they have been alive at least 20 years longer than you." This doesn't mean that the mother and daughter relationship can't be very close and satisfying.

    While some adult relationships are still troubled, many find them to be extremely rewarding. This generation of mothers and adult daughters has a lot in common which increases the likelihood of shared companionship. Mothers and daughters have always shared the common experience of being homemakers, responsible for maintaining and passing on family values and traditions. Today contemporary mothers and daughters also share the experience of the workforce and technology, which may bring them even closer together.

    Best friends may or may not continue to be best friends, but for better or worse, the mother and daughter relationship is permanent, even if for some unfortunate reason they aren't speaking. The mother and child relationship is closer than any other. There is not an equal relationship. Daughters should not feel responsible for their mother's emotional well-being. It isn't that they don't care deeply about their mothers. It's just that they shouldn't be burdened with their mother's well being.

    The mother and daughter relationship is a relationship that is not replaceable by any other. Mothers never stop being mothers, which includes frequently wanting to protect their daughters and often feeling responsible for their happiness. Mother always "trumps"(王牌) friend.

    Born in Detroit, Michigan, on January 10, 1928. Philip Levine was formally educated in the Detroit public school system. After graduation from university, Levine worked a number of industrial jobs, including the night work in factories, reading and writing poems in his off hours. In 1953, he studied at the University of Iowa. There, Levine met Robert Lowell and John Berryman, whom Levine called his "one great guide."

    About writing poems, Levine wrote: "I believed even then that if I could change my experience into poems I would give it the value and honor that it did not begin to have on its own. I thought too that if I could write about it, I could come to understand it: I believed that if I could understand my life-or at least the part my work played in it-I could write it with some degree of joy, something obviously missing from my life."

    Levine published (出版)his first collection of poems. On the Edge in 1961, followed by Not This Pig in 1968. Throughout his life. Levine published many books of poems, winning many prizes. A review said: "Levine writes poems about the bravery of men, physical labor, simple pleasures and strong feelings, often set in working-class Detroit or in central California, where he worked or lived."

    He taught for many years at California State University, Fresno, and served as Distinguished Poet in Residence for the Creative Writing Program at New York University. After retiring from teaching, Levine divided his time between Brooklyn, New York, and Fresno, California, until his death on February 14, 2015. His final poem collection, The Last Shift, as well as a collection of essays(短文)and other writings, My Lost Poets, A Life in Poetry, were published in 2016.

    Microsoft announced this week that its facial-recognition system is now more accurate in identifying people of color, touting (吹嘘)its progress at tackling one of the technology's biggest biases (偏见).

    But critics, citing Microsoft's work with Immigration and Customs Enforcement, quickly seized on how that improved technology might be used. The agency contracts with Microsoft for cloud-computing tools that the tech giant says is largely limited to office work but can also include face recognition.

    Columbia University professor Alondra Nelson tweeted, "We must stop confusing 'inclusion' in more 'diverse' surveillance (监管)systems with justice and equality."

    Facial-recognition systems more often misidentify people of color because of a long-running data problem: The massive sets of facial images they train on skew heavily toward white men. A Massachusetts Institute of Technology study this year of the face-recognition systems designed by Microsoft, IBM and the China-based Face++ found that facial-recognition systems consistently giving the wrong gender for famous women of color including Oprah Winfrey, Serena Williams, Michelle Obama and Shirley Chisholm, the first black female member of Congress.

    The companies have responded in recent months by pouring many more photos into the mix, hoping to train the systems to better tell the differences among more than just white faces. IBM said Wednesday it used 1 million facial images, taken from the photo-sharing site Flickr, to build the "world's largest facial data-set" which it will release publicly for other companies to use.

    IBM and Microsoft say that allowed its systems to recognize gender and skin tone with much more precision. Microsoft said its improved system reduced the error rates for darker-skinned men and women by "up to 20 times," and reduced error rates for all women by nine times.

    Those improvements were heralded(宣布)by some for taking aim at the prejudices in a rapidly spreading technology, including potentially reducing the kinds of false positives that could lead police officers misidentify a criminal suspect.

    But others suggested that the technology's increasing accuracy could also make it more marketable. The system should be accurate, "but that's just the beginning, not the end, of their ethical obligation," said David Robinson, managing director of the think tank Upturn.

    At the center of that debate is Microsoft, whose multimillion-dollar contracts with ICE came under fire amid the agency's separation of migrant parents and children at the Mexican border.

    In an open letter to Microsoft chief executive Satya Nadella urging the company to cancel that contract, Microsoft workers pointed to a company blog post in January that said Azure Government would help ICE "accelerate recognition and identification." "We believe that Microsoft must take an ethical stand, and put children and families above profits," the letter said.

    A Microsoft spokesman, pointing to a statement last week from Nadella, said the company's "current cloud engagement" with ICE supports relatively anodyne(温和的)office work such as "mail, calendar, massaging and document management workloads." The company said in a statement that its facial-recognition improvements are "part of our going work to address the industry-wide and societal issues on bias."

    Criticism of face recognition will probably expand as the technology finds its way into more arenas, including airports, stores and schools. The Orlando police department said this week that it would not renew its use of Amazon. com's Rekognition system.

    Companies "have to acknowledge their moral involvement in the downstream use of their technology,"

    Robinson said. "The impulse is that they're going to put a product out there and wash their hands of the consequences. That's unacceptable."
