You've probably heard about sports coaches, fitness coaches, voice and music teachers, career counselors（咨询） psychiatrists (精神科医师) and other specialists who teach skills and help us cope with daily life.

    But there's a rapidly growing kind of professionals who do a little bit of everything. She or he is called a “ life coach”. People who are at the crossroads in their life, and corporations that want to give certain employees a career boost , are turning to them for help.

    The idea that one person's success story can change other people's life for the better goes back at least to the 1930s. Dale Carneigie's famous self-improvement program “ How to Win Friends and Influence People” came along soon thereafter.

    But this new style of life coaches includes more than enthusiastic speakers or writers. They use their own experiences in business, sports, military service, or psychotherapy (心理疗法) to help others make critical life decisions. They often give their approaches a slogan, such as “energy coaching” or “fearless living” or “working yourself happy”.

    Dave Lakhani in Boise, Idaho, for instance, works with salespeople to develop what he calls a “road map”. He says an ongoing relationship with a coach is like having a personal fitness trainer for one's career and life outside work.

Lakhani's Bold Approach coaching firm also donates some of its time to help people who are anything but successful—including battered (殴打) women and struggling single mothers.

    But others in the so-called “helping professions” are not thrilled about the life-coaching movement. They say that anyone, trained or untrained, can call himself or herself a life coach, and that slick(华而不实的) promoters who mess with people's lives can do more harm than good.

    China has the highest adoption rate in the world for technology-enabled payment systems, according to a report released on Wednesday. The report, from the market research firm Nielsen, is based on a survey of 13,000 respondents in 26 countries.

    The survey showed that 86 percent of Chinese respondents said they paid for online purchases during the past six months via digital payment systems compared with a global average of just 43 percent.

    "Chinese consumers have more payment choices for products and services than ever while digital payments will continue to win over more Chinese consumers due to its convenient nature," said Kiki Fan, managing director of Nielsen China.

    The increasingly popular payment method is part of the rapidly evolving purchasing behavior of Chinese consumers. About 98 percent of the respondents in China, the world's largest e-commerce market, said they had made purchases online.

    The majority of them still make online purchases via computers, but the number of those who use mobile devices to make purchases is growing fast and is significantly higher than the average in other surveyed countries.

    At 71 percent, food-related businesses topped the list of purchases made via smart phones while event ticket purchases stood at 51 percent.

    The rising use of digital payments has attracted numerous players to the Chinese market.

    Apple Inc launched its contactless payment system Apple Pay in the Chinese mainland last month. It allows users of the iPhone 6 or more advanced versions, certain iPads and Apple Watches to pay by their devices in bricks-and-mortar stores.

    Apple's rival Samsung Electronics Co Ltd is expected to bring its own mobile payment service to China in mid-March—Sam-sung Pay.

    China's Internet giants Alibaba Group Holding Ltd and Tencent Holdings Ltd have already taken about 90 percent of the mobile payment market, but industry observers said the competition is just about to start.

My Experience in Ghana

    I decided to take part in an exchange program in Ghana. The 30 of us participating in the program met up the first morning in Ghana to meet Fred, our guide in Ghana.

    We boarded the bus to Senase, a village of 3,000 in Northwest Ghana. Once we got to the village, we were greeted by the queen mother and the other elders. A young girl performed a dance for us with Ghanaian drums, and then the elders each thanked us for coming to the village and helping their children and their schools.

    After our meeting ended, we split up into three groups and went to different schools, spending most of the day handing out toothbrushes and school supplies, meeting with the children, and playing games with various classes. It was really interesting to see the schools and to see what all of the different classes were learning.

    We got back to our host's house that night literally seconds before the skies opened up over Senase, and since the power was out, Fred, Cari (my roommate) and I sat out under the roof listening to the pouring rain and talking about our lives. We were able to hear Fred's story, which was absolutely incredible. I can say it gave me a new sense of respect for the Ghanaian people, their unity in the face of tremendous hardship, and the immense amount of care and love they hold in their hearts, not only for their families but their entire community.

    The next day we performed our dance for one of the schools, to the delight (and laughter) of the children, queen mother, and principal. After that we were on the bus heading back.

    During the bus ride, new thoughts and questions filled my mind. Where is this fire Senase lit in my heart going to take me, and how can I feed it and build it into real change? How do I bring this back to my community, and then back home to my family and friends? These were only a few of the questions that I was struggling with and continue to struggle with, and I can't say I have found any answers yet. All I know is that Senase did light a fire within me, and I refuse to ever let it burn out.

    Rescue officials in Poland are working quickly to clear one of the country's highways. The roadway is covered with a sticky brown material. It is blocking cars from both directions.

    What is causing the mess? Milk chocolate. The problems began early Wednesday, after a huge truck carrying many tons of liquid chocolate overturned. Chocolate spilled out. It spread across six driveways of Poland's A2 highway.

    The liquid chocolate solidified（凝固）as it cooled, causing even more difficulties. The accident happened near the western Polish town of Slupca. Bogdan Kowalski is with the fire fighters of Slupca. He told the Associated Press that “the cooling chocolate is worse than snow”.

    Videos published on social media showed rescuers and cleaners were trying to move the sticky brown mess with a bulldozer（推土机）.

    The private Polish broadcaster TVN24 reported that the driver of the truck was taken to a hospital with a broken arm. The accident happened in the morning when there was little traffic. Nobody else was harmed.

    The sticky situation became a hot topic on social media. Some people offered to help the clean-up workers by eating the chocolate themselves.

    Marlene Kukawa is a media officer for Slupea police. She told the New York Times that rescue workers needed to remove the truck from the highway first. “The cleanup”, she said at the time, “will take a few hours or more.” She added that accidents are rare in this part of the A2 highway. And, she told the New York Times, she is sure the area has never experienced something quite like a huge chocolate spill.

    One day a very skilled artist met a beautiful woman who immediately became the object of his affections. As he observed her and spoke with her, he admired her more and more. He showered her with kindness and words of praise until she consented to be his wife.

    Not long after they were married, however, the beautiful woman found out that she was more the object of his artistic interest than of his affections. When he admired her classic beauty, it was as though he were standing in front of a work of art rather than in front of a human being to whom he had pledged his love and promised his life. And soon he expressed his great desire to put her rare beauty on canvas.

    “Please sit for me in the workroom,” he pleaded, “and I will make your beauty permanent. The work will be my masterpiece!”

    She was humble and patient as well as flattered by his words, so she said, “Yes, my love. I will be happy to sit for you.” So the beautiful, young wife of the artist sat meekly for hours in his studio, not complaining. Day after day she sat patiently, smiling as she posed, because she loved him and because she hoped that he would see her love in her smile and obedience. She sometimes wanted to call out to him, “Please love me and want me as a person rather than as an object!” But instead, she spoke nothing but words which pleased him.

    At length, as the labor drew to close, the painter became wilder in his passion for his work. He only rarely turned his eyes from the canvas to look at his wife. As he stood there gazing at his beautiful work of art, he cried with a loud voice, “This is indeed life itself!” Then he turned to his beloved and saw that she was dead!

    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.
