People are always looking for lost cities and occasionally one is found: Borobudur in Indonesia, for example. But perhaps some of the places people look for never existed — or did they? Here are just a few famous mythical (传说中的) cities.

    El Dorado

    El Dorado is a story that began in 1537, when Spanish explorers found the Muisca people in the mountains of what is now Colombia. They heard the story of a man who covered himself with gold and dived into a lake. Then people began to talk of El Dorado — 'the golden man'. Soon people started to think of El Dorado as a place, too — a city of gold and amazing riches. Nowadays, the name 'El Dorado' is still used to mean 'a place where you can get rich quickly'.

    Atlantis

    There was once an island in the middle of the Atlantic Ocean. It was the mythical island of Atlantis. The people of the island were very rich, thanks to the natural resources (资源) on their island. For hundreds of years, they lived simple lives. But slowly they began to change. They started to want power. So the gods decided to destroy Atlantis. Suddenly, the island and its people were swallowed (淹没) by the sea and were never seen again.

    Shambhala

    In Tibetan Buddhist tradition, Shambhala is a mystical (神秘的) country that is hidden somewhere behind the Himalayas. Shambhala is a word from an old language that means 'place of peace' or 'place of happiness'. It is said that there is no war in Shambhala, and in the future, when the world is full of war, a huge army will come out of Shambhala, destroy the world's bad rulers, and start a new Golden Age. Some people say this will happen in 2424.

    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 voice­activated digital assistant, while robots are deployed to serve dishes, cocktails and coffee. Hotel bookings and check­out can also be done with a few clicks on mobile through an app. "The AI­based 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 companies' attempt into traditional industries such as the hotel industry.

    E­commerce 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 QQfamily, 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."

How to Drop a Pant Size in a Week

    Dropping one pant size in seven days is a difficult task, but with dedication, exercise and the right diet, you can make it happen.

    Increase your water consumption. Thirst is often misinterpreted as hunger, and if you are drinking the right amount of water, you will find it much easier to avoid snacking. Look to drink at around eight or nine glasses of water every day.

    Lower your calorie count. You can use a calorie calculator to determine how much you need to take in to maintain or lose weight. If you take in fewer calories than you burn each day, you will lose weight as a result. As a rule, an average-sized woman needs to take in less than 1, 300 calories per day for extreme weight loss, as you'll naturally burn around 2,000. Exact measurements differ based on age, height, weight and activity level.

    Cut the junk food. Chips, soda and candy seem harmless if taken as snacks, but can seriously affect your weight loss. Limit yourself to one or two snacks per day and switch your usual snack foods for baby carrots, apples and grapes.

    Break up your meals. If you want to lose weight, try eating four or five small meals per day instead of two or three large ones. This makes it easier for your body to process what you are consuming. Divide your required calories by the number of meals you'll be eating to determine how large each meal should be. Space your meals out two or three hours apart—try meals at breakfast, mid-morning, lunch, afternoon and dinner.

Doing intense aerobic (需氧的) exercise. You have to encourage your body to burn calories if you want to drop pounds and inches. Running is by far the fastest calorie burner, with the potential for 986 calories per hour. If you're unable to run, use an elliptical machine (椭圆机), jump rope, or participate in a high-impact aerobics class.

    An online supermarket company—Ocado in the UK, has recently displayed a robotic hand that can pick fruits and vegetables!

    When an embryo (胚胎) is in the womb, the very first sense it develops is touch. The sense of touch is also the one that lasts the longest—as we get older and our vision and hearing begins to weaken, touch still remains. Humans use their touch to protect themselves, to create emotional relationships with other people, and to experience pleasure. Can you imagine life without it?

    The sense of touch comes from a network of nerve endings and special touch receptors on the surface of the skin. While there are different kinds of touch receptors (感受器), they help us judge pressure, texture and vibrations (震动). They are located in our fingertips, palms, soles of our feet, face, lips and tongue.

    When we touch something, the mechano-receptors perceive the touch and through a network of nerves, send signals to the brain. This informs the brain about the location of the touch, the amount of force used, and the speed at which it was used.

    Several different techniques have been tried in the past to create such a robotic hand—using three fingers. But this latest design by SoMa copies the human hand. The gripper (夹具) is made up of flexible materials which grasp onto the thing based on its size and shape. Then air pressure is used to control the movement of the robotic fingers to pick objects safely and without causing damage.

    The next step would be for the robot to judge how ripe the fruits and vegetables are, and apply pressure accordingly. Members of the research team are currently working on adding computerized vision to the robots, so that they can see what they are gripping.

    Does all this mean robots can replace people? According to Ocado, it helps improve productivity by removing some of the repetitive tasks done by humans.
