For the Travel section, writers and editors selected special items to profile from a dozen cities.

Brussels:Chocolate

    Nearly half the chocolate consumed in the world is eaten in Europe, and Belgium—with average consumption of 14.99 pounds per person a year—certainly covers its fair share. While Brussels, the country's capital, is home to hundreds of chocolate makers, what makes a visit necessary is the rich heritage of traditional chocolate makers.

Budapest: Paprika (红辣椒)

    The job of preparing Hungarian paprika was once considered too dangerous for mothers to do. A woman who touched her children upon returning from work risked burning them, so only the elderly and unmarried were allowed the delicate task of separating the skin from the flesh. But by the early 20^th century, sweeter varieties and a machine turned paprika into a common feature of all Hungarian cuisine.

Lisbon: Tiles (瓷砖)

    Is there a bluer Country than Portugal? The blue sky and Atlantic Ocean embrace the land. The blue moods of Fado, the dark folk music, form the national soundtrack. And all across Portugal, the typically blue designs of azulejos—ceramic tiles—are spread across churches, castles, palaces, university halls, parks... The result is a beautiful land of Christian saints, Portuguese kings, historical glories, aristocrats at leisure, seascapes and so on.

Madrid: Guitars

    Walking into one of Madrid's storied guitar makers' workshops can feel like stepping into the past. Curly wood shavings, from the palest pine to ebony, fall onto the floor as artisans turn some humble wood into works of art. It's painstaking work—all done by hand—with classical guitar models and the methods of making them changing little over the last century.

    When Ron first started with his organization, he loved his job. He went into work every day filled with purpose and passion (热情). Three years later, however, it was hard to recognize him. Now, Ron detests going to work. He feels that his work is meaningless, he's always stressed, and he calls in sick frequently.

    These are basic symptoms (征兆) of burnout. If you've experienced this yourself, it's important that you should know how to recover from it before you have difficulty in having a sense of satisfaction and then dislike your job.

    You first need to know why you've experienced burnout. First, look at any resentment (愤怒) that you feel towards your work. Often, feelings of resentment point to something important that is missing.

    Here's a good example. Jennifer manages a team around the world, so her workday often starts at 6 a.m. She doesn't mind this because she likes her team and her job. But she feels resentful when her boss forgets that she starts work so early and repeatedly asks her to stay late, which causes her to miss important time with her family.

    In this example, burnout wouldn't happen if Jennifer disliked her job; in fact, she loves what she does. She experiences burnout because she hates missing out on family time in the evenings.

    Take time to think about any negative feelings that you have about your role, and try to get to the root of the problem. Once you've known the cause of your burnout, write down at least one way that you can manage that source of stress. This might include giving some of your duties to others, working from home one day a week, or even changing roles.

    One day, when I was working as a psychologist（心理学家）in England, an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me. “This boy has lost his family,” he wrote. “He is understandably very sad and refuses to talk to others, and I'm very worried about him. Can you help?”

    I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn't have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically（同情）

The first two times we met, David didn't say a word. He sat there, only looking up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon—in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.

    Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company（陪伴）. But why did he never look at me?

    “Perhaps he simply needs someone to share his pain with,” I thought. “Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.

    “It's your turn,” he said.

    After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times, about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.

Maybe I gave David something. But I also learned that one…without any words—can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.

    Do you love Beats headphones, True Religion jeans, and UGG shoes? These are some of the most popular brands(品牌) around. They are also expensive. But some experts say they are not much better than cheaper brands.

    For example, Jim Wilcox works for Consumer Reports. He tested all kinds of headphones. He says that $80 Koss Pro headphones provide basically the same quality and comfort as Beats. So why do people pay twice or even 10 times as much for the hottest brands?

    Experts say because it's fashionable, and expensive brands send a message. Brands say "I belong" or "I can afford it."

    Some people think that expensive brand names are worth the price. They say that some designer clothes are really of top quality and that they last longer than cheaper brands. Some teenagers choose to wear popular brands because these brands make them feel good about themselves.

    Alexandra Allam, 17, likes to buy brand-name products. "I'd rather spend the extra money getting something I know I'll be satisfied with." she says. Her friend Emmy Swan agrees, saying "As long as you can afford it, it seems reasonable to buy what you want." But not all teenagers agree. "Spending hundreds of dollars for designer is stupid and unreasonable," says Daniel Steinbrecher, 16. "It's fake（假的）happiness."

    People who are against wearing expensive brand names say that many designer brands aren't any better. "It's wasteful to buy things just because they are popular." says Edmund Williams, 15. "You'll feel better if you buy things because you like them. If you have extra money to spend, it would be better to give it to people in need."

    Many people prefer eating out instead of cooking at home. A change appears to be taking place, though, and millennials are leading the way. According to one survey, more young people are starting to cook at home for three basic reasons: They can save money, eat healthy and waste less food.

    Popular TV chefs are also getting millennials excited about learning some basic cooking skills. Many millennials view cooking as a form of entertainment and self-expression. They proudly post pictures of their cooking creations on Facebook or Instagram, and invite friends over to share the cooking experience.

    Many millennials have also found ways to avoid wasting food. After roasting a chicken, they put the leftover bones in their freezer instead of the garbage can. Later, they use the bones to make chicken stock which is an important ingredient in many dishes.

    They also hate throwing out fruit that's too old. To avoid that situation, they bake ripe fruit like berries and bananas for 15 minutes at 175 degrees C. Then they freeze it overnight. After that, they place the fruit in plastic bags and store it their freezer for later use.

    Now any millennials only eat at restaurants that have excellent food-waste policies. These servants use every part of the vegetables they buy, including their stems and roots, in dishes. They also use beef, chicken and pork bones to make their own stock.

    Millennials also reduce food waste by only buying what they require. Before going to a market, they write down what they need and don't buy anything else. They say they won't purchase more food than they can consume.

Music is all around us. It's an accessible and popular art form which accompanies our daily lives. Advertisers have long understood the popularity and emotional power of music and capitalized on it. They spend much time and money securing the right soundtrack (配乐) for an advertisement in order to boost sales. For example, Microsoft spent a reported US$3 million using Start Me Up as part of their advertising campaign for Windows 95.

As one researcher puts it, "Music expands pictures and colors words, and often adds a form of energy available through no other source." This is supported by other studies, which suggest that music matching the main message of an advertisement has a positive effect on consumer engagement. This is known as "musical congruity" and can result in better attention, a positive emotional response, finally improving the effectiveness of an advertisement.

Take the simple but interesting advertisement for Air France, with the soundtrack of Mozart's Piano Concerto No.23, for example. It projects greatness and elegance in the hope that viewers will associate those qualities with the airline. The research, which looked at hundreds of viewer comments about the music used in advertising, suggested it was successful.

Music is also effective at arousing (唤醒) emotional memories in advertisements creates associations with consumers' past experiences. A good choice of music allows businesses to tap into this nostalgia for commercial benefit.

However, the use of popular music in advertising can also arouse arguments between artistic effort and commercialism. Some people believe a work of art shouldn't be used for the pursuit of profit. The findings of study showed that consumers sometimes passionately oppose the use of music produced by respected musicians in advertisements, as they believe that it destroys the aesthetic integrity (美学完整性). For example, Nike's use of the Beatles' song Revolution was seen by some as using John Lennon's music to sell shoes. It made some Nike wearers so angry that they refused to buy the products.
