They wear the latest fashions with the most up-to-date accessories(配饰). Yet these are not girls in their teens or twenties but women in their sixties and seventies．A generation which would once only wear old-fashioned clothes is now favouring the same high street looks worn by those half their age．

    Professor Julia Twigg, a social policy expert, said, “Women over 75 are now shopping for clothes more frequently than they did when they were young in the 1960s．In the 1960s buying a coat for a woman was a serious matter．It was an expensive item that they would purchase only every three or four years — now you can pick one up at the supermarket whenever you wish to．Fashion is a lot cheaper and people get tired of things more quickly.”

    Professor Twigg analysed family expenditure(支出) data and found that while the percentage of spending on clothes and shoes by women had stayed around the same — at 5 or 6 percent of spending — the amount of clothes bought had risen sharply．

    The professor said, “Clothes are now 70 percent cheaper than they were in the 1960s because of the huge expansion of production in the Far East．In the 1960s Leeds was the heart of the British fashion industry and that was where most of the clothes came from, but now almost all of our clothes are sourced elsewhere．Everyone is buying more clothes but in general we are not spending more money on them．”

    Fashion designer Angela Barnard, who runs her own fashion business in London, said older women were much more affected by the celebrity(名流) style than in previous years．

    She said, “When people see stars such as Judi Dench and Helen Mirren looking attractive and fashionable in their sixties, they want to follow them．Older women are much more aware of celebrities. There's also the boom in TV programmes showing people how they can change their look, and many of my older customers do yoga to stay in shape well in their fifties．When I started my business a few years ago, my older customers tended to be very rich, but now they are what I would call ordinary women．My own mother is 61 and she wears the latest fashions in a way she would never have done ten years ago．”

    Computers have beaten human world champions at chess and, earlier this year, the board game Go(围棋). So far, though, they have struggled at the card table. So we challenged one AI(artificial intelligence) to a game.

Why is poker so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an “information incomplete” game. Players have to guess opponents' hands from their actions—-tricky for computers. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

    Scientists believe it is only a matter of time before AI once again vanquishes humans, so our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, a researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

    Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

    Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

    After two hours of quite defensive play, from the computer at least, we called it a draw.

    After decades of playing catch-up with the U.S. and Russian space programs, China did something neither nation nor any other had done this December: land a spaceship on the dark side of the moon.

    Strictly speaking, of course, the moon has no dark side. But because of the way it orbits Earth, our natural satellite shows us only one side－the other is hidden from our view. No one even saw the far side until 1959, when the Soviet Luna 3 spaceship flew around for a look and sent back photos. No astronaut or spaceship went there until this December, when the China National Space Agency (CNSA) launched a 2,500-pound lander called Chang'e-4 to the southern end of the lunar far side.

    Chang'e-4 operated a small rover (探测车) to survey the geography there for the first time ever. By examining the geography of its landing area, Chang'e-4 could solve longstanding puzzles about the moon, including how it formed 4.5 billion years ago. Chang'e-4 also carried a very small lunar biosphere (生态圈) containing silkworm eggs and a tiny greenhouse designed to grow potatoes in order to study the growth of the seeds on the moon.

    Besides Chang'e-4, China plans to launch Chang'e-5 in 2019. Its mission will be to gather moon rocks using an orbiter, a lander or collector, an ascent stage (上升器) and a capsule that will separate from the orbiter and return the rocks to the earth. ―With these missions, the Chinese will have shown complete mastery of flight in the space between the earth and the moon, said Paul Spudis, an experienced lunar researcher based in Houston.

    CNSA has already outlined ideas for Chinese astronauts to follow the robots to the moon. Pei Zhaoyu, deputy director of CNSA's Lunar Exploration and Space Program Center, told that China plans a permanent robotic lunar station in about 10 years and suggested a human presence on the moon another decade or so after that. Spudis said China's ambitious Chang'e-4 and Chang'e-5 missions should send human's plans for lunar return into rapid development.

    Do your children like to see adventure movies? The following are four adventure movies for kids.

    Toy Story

    In this story, toys come to life when nobody is watching. Woody, a cowboy doll, feels unhappy when a new spaceman figure Buzz takes his place as the favourite toy of six-year-old Andy. Buzz and Woody get into a fight and get trapped together in the next-door neighbour's house and they have to find their way home. In that journey, they form a close friendship and work together through everything.

    How to Train Your Dragon

    Young man Viking Hiccup wants to fight against the dragons that continually attack his town. But after finally catching his first dragon whom he names Toothless, Hiccup realizes that he no longer wants to kill it and instead treats it kindly. He learns that his people have misjudged the species.

    Up

    The story is about Carl Fredrickson, a 78-year-old man who sets out to realize his lifelong dream of seeing the wilds of South America. He ties thousands of balloons to float his house and to travel to Paradise Falls with an unwelcome companion Russel, who is an eight-year-old explorer.

    Despicable Me

    Gru wants to become the greatest thief by stealing the moon right out of the sky but he meets a challenge. The three girls he had adopted (收养) change his life in a way nobody would consider possible. The world's greatest villain (坏人) ends up being from being super-bad to a super-dad.

    HANGZHOU-Chinese internet giant Alibaba on Tuesday opened a hotel loaded with artificial intelligence (AI) and robots, automating a series of procedures like check-in, lights control and room service.

    FlyZoo Hotel, opened in Hangzhou, capital of East China's Zhejiang province, where Alibaba is headquartered, is known as the company's first "future hotel". Customers can check into the hotel by simply scanning their faces. The facial recognition system installed in the hotel also enables customers to use their faces as key cards to open doors and access another hotel service. Users can also control the lights, televisions and curtains in the room via Alibaba's voice-activated digital assistant, while robots are deployed to serve dishes, cocktails and coffee. Hotel bookings and check-out can also be done with a few clicks on mobile through an app. The Al-based solution can help customers save time and relieve hotel employees from repetitive work," said Wang Qun, CEO of FlyZoo Hotel. The hotel is the latest example of Chinese tech companies1 attempt into traditional industries such as the hotel industry.

    E-commerce giant JD.com announced in October its strategy to put smart home and electronic devices sold on its platform into hotels, in an effort to improve online sales.

    In July, Baidu teamed up with Intercontinental Hotels Group in Beijing to allow guests to use its voice-controlled assistant to adjust room temperature and order room service at ease.

    Before that, social media giant Tencent introduced QQ family, a similar tech solution for hotel operators, in the southern city of Zhuhai last year.

    "We want to install a 'smart brain' for hotels, " said Wang, "In the future, we will continue to make hotels smarter and more automated, as well as create more personalized experiences for consumers."

Here is a story about social media bringing people together.56-year-old Lucy Shepherd was 1 as an infant (婴儿) in the early 1960s. When she turned 18, Lucy 2 to look for her birth parents. She managed to find her mother ten years later. However, finding her father proved to be more 3 .

About her father, Lucy knew few 4 and was only told by a social worker that he was an electrician named Jonah Larson. She tried to find him out but with little information she 5 — until decades later when she saw the 6 appear on the "Suggested Friends" list of the social media site Facebook. After looking through his online profile (简介), she realized she might be indeed 7 her father. 

The pair then 8 for several weeks before meeting for the first time last week — and they both said it was like they "have 9 each other their whole lives". 

"It's 10 . I live in Kentucky and she lives 350 miles (about 563 km) away in Cornwall. And we had been 11 for nearly 56 years. The chances of actually 12 were so slim." said Jonah. The 13 took place in Dorset, roughly halfway between Cornwall and Kentucky. When they first spotted (看见) each other, the father opened his 14 and gave Lucy a big hug. "I love you!" said Jonah, looking straight into her eyes, and they hugged 15 .

"Now there is someone else like me, loving me for me. I'm incredibly blessed to find him." said Lucy excitedly.
