The Bowler family had a very unusual experience this year. It was one of more than 400 families who applied to 1900 house, a reality TV show which took a typical family back a hundred years to see how people lived in the days before the internet, computer games and even electricity.

    The Bowler family spent three months in a London home without a telephone, computers, TV, or fast food. The bowlers wore clothes from 1900, ate only food available in England at that time, and cooked their meals on a single stove. Paul Bowler still went to work every day in a then uniform. The children changed their clothes on the way to and from school and their classmates didn't know about their unusual home life. Joyce stayed at home, cooking and cleaning like a typical housewife of the time, though everything took three times as long.

    So does Joyce think that people's lives were better in the old days?

    “I think people in the old days had just as many troubles and worries,” Joyce said. “And I don't think their life was better or worse, there were lots of things back then that I'm happy I don't have to deal with nowadays, but on the other hand life was simpler.” “We had a lot more time with our family, and it was hard being nice to each other all the time,” eleven-year-old Hilary said.

    So what did the Bowler family miss most about modern life while living in the 1900 house?

Paul, 39: “telephone and a hot shower”

Joyce, 44: “a quick cup of tea from a kettle you could just turn on”

Hilary, 11: “rock CD”

Joseph, 9: “hamburger and computer games”

    Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who findsit.

    Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce Peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    For years now, I've been wanting to sell our house, the place where my husband and I raised our children. But to me, this house is much more than just a building.

    In the front room, there's a wall that has hundreds of pencil lines, marking the progress of my children's growth. Every growth stage is marked in grey, with each child's name and the date when they were measured. Most people I know have been featured on a wall like this, or at least had a wall like it in their home.

    Of all the objects and memories, it is this thing in a home that is the hardest to leave behind. Friends I know have returned home after work only to discover their wall of heights has been freshly painted over. A new paint job wouldn't normally be greeted by tears, but erasing that evidence of motherhood hurts more than it should. Our children grow in so many ways, but the wall is the physical evidence of their progress, right there for everyone to see.

    Over the years, I've talked about how much I would hate leaving that wall behind when I moved, even though the last marks were made 10 years ago when my children stopped growing.

    So one day, while I was at work, my children decided to do something about it. They hired Jacquie Manning, a professional photographer. She came to our house, and over several hours, took photos of the hundreds of drawings and lines, little grey fingerprints and old marks. Somehow, she managed to photograph all those years of memories perfectly. Afterwards, she put all the photos together into one image, changing them into a beautiful history of my family.

    Three weeks later, my children's wonderful gift made its way to me — a life-size photo of the pencil lines and fingerprints that represents an entire lifetime of love and growth.

    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.

    A new study suggests that people who drank a certain amount of alcohol（酒）had a lower risk of cancer and death than those who drank more or none during a nine-year period. And with each additional drink a week, the risk of cancer and death from any cause increased, the scientists reported.

    However, the study found only an association between alcohol and cancer and death, and did not prove cause and effect, the researches said. What sets the new study apart, said lead study author Andrew Kunzmann, is that previous studies looked at cancer and death separately. “What our study does is combine the two outcomes together and we find that lighter drinking is associated with the lowest risk of cancer or death,” Kunzmann said.

    But Kunzmann noted that the participants（参与者）were all older adults. That means that “we're not really showing what happens in younger people if they drink,” he said. Also, it's difficult to account for other lifestyles that could have affected the results. “These could also influence health. But the results did take into consideration differences in diet, smoking and education among participants,” Kunzmann noted.

    The researchers said that they hope their study sparks conversation about reducing the suggested alcohol intake in countries' guidelines. “We're not telling people what they can or can't do or what they can or can't drink,” Kunzmann said. “We're just trying to give them reliable evidence so that they can make their own informed, healthy decisions.”

    A few years ago, bubble tea(奶茶) exploded as a popular drink for Internet foodies(吃货) everywhere. Many take this Taiwanese drink as a guilt-free snack similar to juice or a cup of coffee. After all, it has the word "tea" in it, so it has to be healthy…right?

    Not quite. Like coffee, bubble tea's ingredients(成分，配料) might not be so bad on their own, but when they're loaded with sweetener(甜味剂) and artificial flavor(人工香料), they lose their nutritional (营养的) value fast.

    It all starts with those "bubbles" found at the bottom of your drink, which are actually round pieces of tapioca(木薯淀粉). Called "tapioca pearls(珍珠)," they're actually made from a vegetable that grows in South America. And as it turns out, those little balls are loaded with sugar—and not the nutritious, fiber-rich(富含纤维) kinds found in whole grains(全麦类), either.

Cooking tapioca pearls only makes it worse. They're typically fried in hot water, along with even more added sugar, for up to three hours. By that point, these balls could have nearly 160 calories per ¼ cup.

    And don't even get us started on what comes in the extra syrups(糖浆). Thanks to all those processed(加工的) ingredients, the average bubble tea can easily reach 300 to 400 calories per cup!

    On top of being an unhealthy habit, bubble tea could even shorten your life. In 2012, a group of German researchers from the University Hospital Aachen reportedly found aspolychlorinated biphenyls, or PCBs, in tapioca ball samples. These cancer-causing chemicals have also been shown to have other bad effects on the immune(免疫), reproductive(生殖), and nervous systems.

    You might want to lay off your bubble tea addiction. Thankfully, we have a few choices for low-calorie, healthier drinks, instead.
