While sweet treats can be hard to resist, the World Health Organization(WHO) has set new guidelines for people around the world. The guidelines, released on Wednesday, advise that both adults and children cut back on their sugar intake(摄取量) to stay healthy.

    In a statement, Francesco Branca, director of the WHO's nutrition department, said there is evidence that reducing daily sugar intake reduces the risk of being overweight and tooth decay(腐烂).

    The guidelines do not apply to the sugars in fresh fruit and vegetables or those that are naturally present in milk. According to the WHO, there is no reported evidence of negative effects of consuming those sugars. Instead, the new guidelines focus on “added” or “free” sugars. These include sugars that are added to processed foods and drinks such as candy and soft drinks.

    Added sugars are sometimes described as “ hidden” sugars because they exist in foods we might not think of as sweets, such as honey and ketchup(番茄酱). Health experts advise that consumers look at ingredients on food packages to help make better-informed decisions.

    The WHO recommends that people in the United States, Europe and other Western societies should cut their average sugar intake by about two-thirds, or down to just 10% of their overall calories. For developing countries, where dental care is less advanced, the WHO recommends that sugar intake be reduced to 5%.

    Scientist Kieran Clarke, of the University of Oxford, notes that for those people who can't shake their love for sweets, getting more exercise is a good solution. “If you get enough exercise, you can eat almost anything,” she said “But it's very hard to avoid large amounts of sugar unless all you're eating is fruit and vegetables.”

    For 80 years, Macy's Thanksgiving Day Parade has kicked off the holiday season with glorious bands, balloons and floats (花车)，and for one day, it has transformed New York City into a living comic book.

    The Macy's Thanksgiving Day Parade is an annual parade presented by Macy's Department Store. It was first held in 1924. It was organized by Macy's employees, most of whom were first­ generation immigrants(移民)，who wanted to celebrate holidays like they did in Europe. The employees dressed in costumes(盛装)and marched on the streets with floats, bands and live animals borrowed from a zoo.

    With an audience of over a quarter of a million people, the parade was such a success that Macy's declared it would become an annual event.

    In 1927 Felix, the Cat became the first parade balloon to float over the city. Large animal­ shaped balloons replaced the live animals from then on. These giant signature(特有的)balloons are by far the biggest attraction of the parade. Each year sees parade balloons adding new characters from comic strip characters to timeless toys.

    One tradition long gone is the releasing of the balloons after the parade. They would float for days and the lucky finder or finders could claim a cash reward if he or she returned the balloon or its remains to Macy's.

    The parade has gone on every year except during World War Ⅱ when, aside from not having much to cheer about, the helium(氦气)air and rubber used for the balloons were needed for the war effort.

    When the parade returned in 1945，it was televised in New York for the first time and also traveled its current route for the first time.

    Nowadays, more than 10,000 people participate in the parade and the National Broadcasting Company(NBC) will nationwide broadcast it live from 9 a.m. to noon. The NBC has even earned several Emmy Awards for this program.

    As always, the parade will end with a visit from Santa Claus. The joyful old man will get settled in Macy's Department Store after the parade to start a­month­long search for who's been naughty and who's been nice.

    As we drove along, my spirits went up again, and I turned, with pleasure, to the thought of the new life which I was entering. But though it was not far past the middle of September, the heavy clouds and strong north-easterly wind combined to make the day extremely cold; and the journey seemed a very long one, so that it was nearly one o'clock before we reached the place of our destination. Yet when we entered the gateway, my heart failed me, and I wished it were a mile or two farther off. For the first time in my life I must stand alone: there was no retreating now. I must enter that house, and introduce myself among its strange people. But how was it to be done? True, I was near nineteen; but, thanks to the protecting care of my mother and sister, I well knew that many a girl of fifteen, or under, was gifted with a more womanly address, and greater ease and self-possession, than I was. Yet, anyway. I would do very well, after all; and the children, of course, I should soon be at ease with them.

    "Be calm, be calm, whatever happens," I said within myself; and truly I was so fully occupied in steadying my nerves and keeping down the rebellious beat of my heart that when I was admitted into the hall and into the presence of Mrs. Bloomfield, I almost forgot to answer her polite greeting; and it afterwards struck me that the little I did say was spoken in the tone of one half-dead or half-asleep.

    With due politeness, however, she showed me my bedroom, and left me there to take a little refreshment for a little while and led me into the dining-room. Some beefsteaks and potatoes were set before me; and while I dined upon these, she sat opposite, watching me (as I thought) and trying to keep something like a conversation— consisting chiefly of commonplace remarks. In fact, my attention was almost wholly absorbed in my dinner: not from appetite, but from the toughness of the beefsteaks, and the numbness of my hands.

    “I have had so little time to attend to their education myself, but I think they are clever children, and very willing to learn, especially the little boy; he is, I think, the flower of the flock— a generous, noble-spirited boy, one to be led, but not driven, and remarkable for always speaking the truth.” “His sister Mary Ann will require watching,” continued she, “but she is a very good girl on the whole, though I wish her to be kept out of the nursery as much as possible, as she is now almost six years old, and might acquire bad habits from the nurses. I have ordered her bed to be placed in your room, and if you will be so kind as to look after her washing and dressing, and take charge of her clothes, she needs to have nothing further to do with the nursery maid.”

    I replied I was quite willing to do so; and at that moment the children entered the room. Tom Bloomfield was a well-grown boy of seven. Mary was a tall girl, for her age of six, somewhat dark like her mother. The second sister was Fanny, a very pretty little girl, looking little younger than Mary. The remaining one was Harriet, a little broad, fat, merry, playful thing of scarcely two, whom I had more desire for than all the rest — but with her I had nothing to do.

    For most of her life, Suanne Laqueur's passion for storytelling was shown on the dance floor.

    Although Laqueur began writing at a young age, dancing always took center stage. She majored in dance and theater at Alfred University and taught at her mother's dance studio in Croton-on-Hudson, New York, for years. But when her mother was ready to retire and an opportunity opened for Laqueur to take over the studio, she realized she had no interest in taking on the business side of her art: “Owning a studio is a lot of work—financially, logistically. I love the teaching, the choreographing(编舞), the staging, but I didn't want to own it.”

    Yet Laqueur's disinterest in running the studio changed when she became a self-published author. In the fall of 2013, she decided to pursue Self-publishing as a way of sharing her first completed novel with friends and family. During the process, she realized that following her true passion—telling stories through writing—made the business of the art worthwhile, and owning that business meant she could direct her writing career however she chose.

    Starting with her second self-published novel, she began investing more time in marketing and building her audience. Her investment paid off. Since 2014, Laqueur, now 49, has self-published six novels, which collectively have hundreds of ratings and reviews on Good reads. Her 2016 novel An Exaltation of Larks stole the show at the 25th Annual Writer's Digest Self-Published Book Awards, topping more than 2,300 entries to win the grand prize.

    “You have to write the most truthful story to you, and I think self-publishing allows that freedom,' she says. “If you work with traditional publishing, it's more about what's marketable, There are trade-offs, which everyone will tell you, but by self-publishing I have control of the book, I have control of the story, and I'm cool with that.”

    In the space of just two years, the app Douyin, created by Beijing-based company ByteDance, has gathered more than half a billion users—around 40%of them outside China—who share short videos of themselves lip-syncing (假唱), cooking, dancing or just being silly. What sets ByteDance apart is its success in the social media category, which is controlled by Facebook, Twitter and Snap—all Western companies.

    ByteDance calls itself an artificial intelligence company. It uses machine learning and algorithms (算法) to figure out what people like most and give them more of what they want to see. On Douyin, people can edit and beautify 15-second videos before posting them online. The app has even made a phrase to describe people glued to their customized feeds: "shua Douyin" or "scrolling through Douyin". Last year, the company released TikTok, the overseas version of Douyin. ByteDance's growing video empire has made it the world's fifth biggest app maker. ByteDance says TikTok and Douyin together have more than 500 million monthly active users.

    Investors like ByteDance because its hundreds of millions of users attract a lot of advertising money. The video apps are lucrative because they attract a lot of users in their teens and 20s, who are more generous with the money. ByteDance also makes money through income sharing deals. People on TikTok, for example, can buy digital coins to give to other people on the app—like throwing money in a performer's tip jar. ByteDance takes a cut of those earnings.

    ByteDance's founder and CEO is Zhang Yiming, a 35-year-old former Microsoft employee. People who have worked with Zhang describe him as someone who thinks deeply about technology and spends much of his free time writing code.

    Like Facebook and Twitter, ByteDance is also battling fake news and inappropriate content. ByteDance promises to add thousands more employees to review content on Douyin.
