What will you think of when it comes to “Hong Kong” and “great swimming”? Shopping sure, but swimming pool? Turns out, along with all its other attractions, Hong Kong is loaded with wonderful pools.

    The Ritz－Carlton

    The pool at the Ritz－Carlton is breathtaking, thanks to the view, the altitude and, of course, the swim. On the 118th floor at 484 meters above the street in the tallest building in Hong Kong, it's the world's highest swimming pool. The ceiling and walls are made up of 144 LED screens displaying coral reefs and other natural scenes.

    W Hotel Hong Kong

    If you have only one nice swimsuit, save it for the W Hotel Hong Kong. Only people living in this hotel can enjoy this wonderful pool, which is Hong Kong's highest rooftop pool. The hotel's signature WET deck is famous for stylish and occasionally wild poolside parties in summer. WET also features a good cocktail bar and a Jacuzzi.

    Hotel Indigo

    One of Hong Kong's unique experiences is swimming in Hotel Indigo's glass bottom pool. The pool protrudes from the hotel, allowing people below to see swimmers and the swimmers to do laps while checking out the traffic below. The pool is smaller compared to other local grand hotels and only available to the hotel guests.

    Four Seasons Hotel

    The Four Seasons Hotel gorgeous infinity pool overlooks Victoria Harbor. Even cooler, the hotel pipes in underwater music, making the swim much more wonderful, or annoying, depending on your taste in music. The pool is open only to hotel guests.

    Many of us live with a roommate at some stage. Sometimes, there can be problems. Who hasn't had an argument about whose turn it is to take out the rubbish or who should be the one to clear up after dinner? However, living with another person also comes with many benefits.

    You know that there's always someone else around, which can help you feel safer. There is always someone to talk to, so you never feel lonely. Besides these obvious benefits, there are some you may not notice. For example, we're actually more likely to eat healthier food when living with others.

    To examine the effect of living alone, Australian university researchers did much research and found that people living alone tended to eat less fresh food, which can have a significant negative effect on long-term health. However, those living with others generally benefited from a more varied diet compared to those living alone.

    What could explain these findings? The researchers believe the social and cultural roles played by cooking, food preparation and eating may be important considerations. For example, those living with friends have someone else to go shopping with, and thus are likely to buy higher-quality fresh food regularly.

    Cooking skills may be another factor. If people living alone find they do not have the knowledge required to prepare a particular dish or cook a certain food, they may fall back on ready-made, less healthy food. However, if they live with at least one other person, they may be able to ask for help.

    In addition, people living alone can eat whatever they want at any time of the day or night. However, it's helpful to have someone around who questions your decision to eat frozen pizza at 3 am. In other words, roommates can draw your attention to unhealthy routines.

    So, if you now live alone and find yourself fighting a losing battle against poor eating habits, why not consider sharing a home with someone else? You could encourage one another on to greater health and well-being.

    In recent years, China has witnessed the growth of luxury (奢侈品) brands. In this market, Chinese consumers are now the largest spenders. It's clear that a new generation of young, materialistic people is increasingly relying on luxury brands to improve its self-image.

I am a fashionist too, at least in spirit—I love to look at clothes and shoes. But I don't understand why people spend lots of money on designer labels.

    When a young woman buys a handbag that costs two months of her salary, that's a scary thing.

    What's interesting is that scientists have found that having luxury things doesn't lead to happiness.

    Study after study has shown that although we want material things, when we get them we don't suddenly become "happy" people. In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, has shown that individuals who spend money on travel and similar experiences get more pleasure than those who invest it in material things. That's because experiences are more easily combined with a person's identity. If I travel to Yunnan, that adventure affects how I think in the future. My memories become a part of me.

    Moreover, as Van Boven has observed, young people who pursue happiness through "things" are liked less by their peers. People prefer those who pursue happiness through experiences.

    It's natural to want to express yourself through your appearance. So my advice is: create a look that isn't tied to a designer label. Convey your own message. Take some lessons from the late Apple co-founder Steve Jobs. He was always in Levis jeans and a black turtleneck. Mark Zuckerberg, founder of Facebook, routinely appears in hoodies and sneakers. These people, successful people, have style. You don't have to break the bank to send a message about who you are.

    Take a trip. Go out into the world. Then come back and confidently create your own signature look.

    With the New Year weeks approaching, you're looking forward to watching the splendid fireworks shows that will welcome 2019 worldwide. Unfortunately, visually impaired and blind people can't experience this joyful celebration. That may change soon thanks to Feeling Fireworks, a fireworks experience invented by the Disney Research Lab in Switzerland.

    To experience the show, users stand before a large flexible screen, place their hands at the base of the screen and move them around to feel the fireworks. Alternatively, their hands can be situated in the center of the screen, where the initial explosions happen, and then moved across to explore other fireworks.

    As the fireworks begin to explode, five nozzles (喷嘴) at the back of the screen start to shoot water, creating movement of water imitating the show. One specializes in the "blooming flower effect", another reproduces the "crackle" effect, and the rest take care of rockets and explosions. A computer controls the timing, and Feeling Fireworks allows users to experience fireworks similar to those in the sky.

    Paul Beardsley, who led the research team, says, "We want blind, visually impaired, and sighted people to all try Feeling Fireworks, and to have a shared and enjoyable memory of a fireworks evening." And the screen displaying the vivid images created by water makes it fun for everyone.

    The low-cost technology is still in its early stage, with only a 66 percent success rate. However, the team plans to continue improving the experience and believes the day when everyone will be able to enjoy the thrill of fireworks shows is not far. When ready, Feeling Fireworks will initially be available only at the Disney theme parks, and then hopefully, at fireworks shows worldwide.

    Nowadays six Amazon Scout delivery robots rolled out in a pilot program in Snohomish County, Wash. The robots carry meals, groceries and packages to homes and offices in this region just north of Seattle. They have appeared on the sidewalks of London, Beijing and other cities and communities worldwide. These machines must overcome pedestrian legs, naughty dogs and broken pavement, which raises some questions.

    These services are gaining attraction as a growing number of city residents expect immediate or scheduled delivery for just about everything. Between 2017 and 2018 online retail sales in the U.S. increased by 16 percent. On the final step of all these deliveries, called the last mile, humans on bicycles, motorized scooters (电动车) or large delivery trucks typically deliver packages. All the vehicles compete for space on busy urban streets. "Deliveries are trending upwards in all crowded city centers, and if city and state leaders don't start thinking about creative solutions like robot deliveries, we can expect even worse traffic jams," says Paul Mackie, director of a transportation policy research center in Arlington.

    A study by this center found 73 percent of delivery vehicles in Arlington were parked outside of authorized areas, often blocking bike lanes and crosswalks. By moving the last step of deliveries from the road to the sidewalk, cities could reduce traffic jams and solve the parking problem entirely, Mackie says.

    Companies such as Amazon are not developing this delivery technology simply to clear up urban traffic. Self-driving vehicles and sidewalk robots could cut down last-mile delivery costs in cities by as much as 40 percent, according to a 2018 report by a consultancy firm. A delivery robot can cost thousands of dollars to manufacture, and most currently require human management and conservation. But in the long run companies that use autonomous delivery vehicles in the next several years could end up saving billions of dollars, the report stated.

 Japan is an island country in the Pacific Ocean. As the Japanese students already know, four main islands and more than 3,000 small ones stretch from north to south for about 1,300 miles. As for the climate of the country, well, it's hot and humid(潮湿) in summer, but it is quite cold and wet in Japan during winter. Typhoons, which are violent tropical storms, often threaten Japan during the fall. That's, of course, during the harvest season.

 The population of Japan is about 110,5 million. It may seem hard to believe, but the average population density(密度) of the country is about 678 persons per square mile.

 About two thirds of the entire population lives in Japan's cities. The other one third lives in the suburbs or in the countryside. No other country in southern or eastern Asia has such a large urban, or city population. Tokyo, the capital city of Japan, is the most density-populated city in the world. At last count there were more than 11.5 million people living in Tokyo.
