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."

    We are naturally drawn to friends and colleagues with familiar voices, scientists have found. People prefer those who have a similar accent, intonation and tone of voice to themselves, they discovered.

    Previous research has focused on how male or female a voice sounds. Men with deeper voices and women with slightly higher voices were thought to sound more attractive, because they suggest a bigger or a smaller body.

    But the new study, published by a linguistics expert in Canada, suggests there is a more complex mechanism (机制) at play. Dr Molly Babel, from the University of British Columbia in Canada, said, “The voice is an amazingly flexible tool that we use to construct our identity. Very few things in our voices are changeless, so we felt that our preferences had to be about more than a person's shape and size.”

    She recorded 30 volunteers' voices and asked each to rate the others' attractiveness on a range from one to nine. Each participant was from western America, with similar accents. The people we assessed were all in the same dialect group, but they showed that dialect to different degrees.

     “We seem to like people who sound like we sound, and we like people who fit within what we know,” Dr Babel said. She also found that breathy voices in women—typified by the famous American actress Marilyn Monroe-were seen as more attractive.

    The breathy tone, caused by younger and thinner vocal cords (声带), implied youthfulness and health. A creaky (咯吱作响的) voice, suggesting a person has a cold, is tired or smokes, was seen as unattractive. The participants preferred men who spoke with a shorter average word length and deeper voices.

    Hip-hop culture covers many fields; it includes spoken words, break-dancing, beat-making, painting, fashion, lively design, technology, and more. Hip-hop is becoming the unofficial music in the education world, as more artists launch school programs, summer camps, and other activities connected city youth in the classroom through the beliefs of hip-hop culture. Even more and more university teachers — who once would have been strongly against hip-hop — have joined the crew. In the past two decades, hip-hop culture, including hip-hop education, has become a legitimate(合法的) field of study in universities and the subject of numerous books.

    Hip-hop culture has influenced every piece of American and global culture because the culture is so prevalent. Teachers must be willing to engage in it if it's part of the unique reality of their students' lives. That way, teachers can truly be effective, reaching students in a meaningful, culturally connected way.

    Teachers might at first feel frightened by hip-hop culture, an area in which they might not have previous knowledge or experience. But a lack of knowledge is actually a blessing; the best trained hip-hop educators have been those that are at the beginning disconnected(分离的) from the culture. One of the biggest sayings in hip-hop is “keep it real”. If a teacher comes to the classroom and says, “I don't know hip-hop, but I recognize that it's your culture and I want to learn,” the kids will teach the teacher, and then the students will be more willing to learn from that educator. Hip-hop is about a respect for youth culture.

    Spotify can tell if you're sad. Here's why that should scare you. Want to figure out if someone is a patient with a mental disability: Ask them what their favorite song is. A New York University study last year found that people who loved Eminem's Lose Yourself and Justin Bieber's What Do You Mean? were more likely to have trouble with mental disabilities than people who were into Dire Straits.

    Over the past few years, Spotify has been improving the ability to analyze information to help businessmen target consumers with advertisements made specially for their needs. They conclude this from the sort of music you're listening to, combined with where and when you're listening to it, along with third-party data that might be available.

    Now, to be clear, there's nothing significantly illegal about what Spotify is doing with your information. I certainly don't think that they are working with shadowy consulting firms to serve you ads selling a culture struggle while you're listening to music that suggests you might be in a terrible situation. However, I find it disappointing that our personal, private moments with music are increasingly being turned into information points and offered to advertisers.

    You can see where this could go, can't you? As ad targeting gets ever more accurate, businessmen will have the ability to target our feelings in potentially improper ways. According to one study, you are more likely to spend more on a product if you're feeling sad. You can imagine some companies might take advantage of that. And on that note, I'm feeling a little down about all this. Head off to treat myself to something expensive.

    Vacation in the U. S. usually means slower days, and no school teachers know, however, that vacation means students will likely fall behind, and forget things they learned during the year. Simon Vanderpool, a special education teacher in Lexington, Kentucky, decided to do something about it.

    He started a program called Books and Barbers. Children go to the barber, choose a book and read out loud while the barber cuts their hair. The child gets a sticker and can take the book home. And there is an added bonus: money. The kids get paid to read.

    Vanderpool says barber shops are places where kids can feel comfortable. "Once a student feels comfortable, that's whenever the brain opens up, and that they are able to start focusing on nothing but learning." Amir Shalash owns a barber shop. But he is doing more than cutting children's hair. He is listening to them read, and helping them with their reading.

    Most of the children getting haircuts at barber shops are boys. Vanderpool's idea was to do more than just help them with reading and money. The teacher wants to help kids who are growing up in a home without a father liike he did. Also, I created the program in order to provide a positive mentor(指导者）for the kids that go into the barber shop, and are able to have someone that they can rely on and they can trust in, and just build a bond between the two of them." Shalash says he and his fellow barbers like being mentors.

    "The biggest thing is that we try to influence as many kids as we can, and that was my whole intention of it."

    Are you familiar with the greeting, "Can I add you on WeChat?" It seems like every time we meet new friends or colleagues nowadays, the first thing that springs to mind is adding each other on the app. Nevertheless, more than 80 percent of WeChat users report feeling stressed or anxious when they receive a large number of messages, according to a study done recently by the app's developer Tencent(腾讯). In other words, WeChat can overwhelm(使应接不暇) us, while also breaking down the boundaries between our work and private lives.

    Just think how easy it is now for bosses to hand out assignments during the holiday, so long as they have your WeChat contact. When you're at the cinema enjoying a romantic movie or having a barbecue in the backyard, you can never cut yourself off from the outside world unless you switch off your phone. Not to post something in WeChat Moments before replying to your boss first!

    Apart from interrupting your leisure time, WeChat can also reduce your productivity at work. For many office workers, logging in to WeChat on their computers at the start of the day has become routine. But what if browsing the Moments distracts us from doing the work? The app steals our time without us even noticing it, making us have the false belief that we are busy all the time.

    And as if that weren't bad enough, there're the "one-off" friends who take up space on our WeChat friend list. A handy way to check how many one-off friends you have is to take a look at your chat history with them. Sometimes, you only sent the initial friend requests so you could invite them to a WeChat group or inform them of something for your boss. Yet still, as your friend count(好友数量) ever goes up, it can make you feel the need to post selfies(自拍) and share details of your life in your Moments, just so you can stay up to date.

    With WeChat, all our spare time is swallowed up by the constant torrent of messages and our attention keeps getting diverted by Moments and pop-up ads. So it's time that we should do something to nip this problem in the bud.
