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 I was nine years old, I loved to go fishing with my dad. But the only thing that wasn't very fun about it was that he could catch many fish while I couldn't catch anything. I usually got pretty upset and kept asking him why. He always answered, "Son, if you want to catch a fish, you have to think like a fish." I remember being even more upset then because, "I'm not a fish!" I didn't know how to think like a fish. Besides, I reasoned, how could what I think influence what a fish does?

    As I got a little older I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature. That is why fish prefer shallow water to deep water because the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. Yet, fish don't have any eyelids(眼皮) and the sun hurts their eyes…The more I understood fish, the more I became effective at finding and catching them.

When I grew up and entered the business world, I remember hearing my first boss say, "We all need to think like salespeople." But it didn't completely make sense. My dad never once said, "If you want to catch a fish you need to think like a fisherman." What he said was, "You need to think like a fish." Years later, with great efforts to promote long-term services to people much older and richer than me, I gradually learned what we all need is to think more like customers. It is not an easy job. I will show you how in the following chapters.

    A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops(笔记本电脑)．

    Students are increasingly using laptops for note­taking because of speed and legibility(清晰度)．But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said.

    In the first experiment，students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note­taking skills. Thirty minutes after the talk，they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand. However，the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.

    The researchers' report said，“While more notes are beneficial，if the notes are taken mindlessly，as is more likely the case on a laptop，the benefit disappears.”

    In another experiment aimed at testing long­term memory，students took notes as before but were tested a week after the lecture. This time，the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding，but that they also lead to superior revision in the future.

    As self-driving cars come closer to being common on American roads, much of the rhetoric（说辞）promoting them has to do with safety. About 40,000 people die on U.S. roads every year, and driver errors are linked to more than 90 percent of crashes. But many of the biggest advocates of autonomous（自动的）vehicles aren't car companies looking to improve the safety of their existing products. Huge support for itself-driving technologies is coming from Silicon Valley giants like Google and Apple.

    Those of us who have studied the relationship between technology and society tend to look more carefully at the motivations behind any technologically push. In this case, it's clear that in addition to addressing safety concerns, Silicon Valley firms have a strong incentive（动机）to create a new venue for increasing the use of their digital devices. Every minute people spend on their mobile phones provides data—and often money—to tech companies.

    At present, digital devices and driving are in conflict: There are serious, often fatal, consequences when drivers use smartphones to talk or to text. Regulators and safety advocates look to resolve dial conflict by banning phone use while driving – as has happened in almost every state. But the tech companies are taking a different approach. The obvious answer for Silicon Valley is creating an automobile in which continuous cellphone use no longer poses a threat to anyone.

    In recent years, the amount of time adults spend on their mobile devices has grown rapidly. At the moment, it's around four hours a day for the average adult in the U.S. However, that rapid growth is likely to slow down as people run out of time that's available for them up to use their devices. Unless, of course, there's a new block of time that suddenly opens up. The average American now spends about 48 minutes in a car every day, a sizeable opportunity for increased cellphone use.

    Sop as the public conversation around autonomous cars highlights the safety advantages, don't forget the tech industry's powerful desire for more profits, which goes well beyond simply saving us from ourselves.

    Winter holiday is coming, time to read something just for fun. You might soon find yourself holding your breath as you turn the pages of a frightening story, or browsing (浏览) the latest novel on your new e-reader. For those of you who want to try some reading in English, but have no idea of what to choose from thousands of choices, we'd like to offer the following books to help you out.

    Talk to the Hand By Lynne Tru

    When did the world get to be so rude? When did society become so inconsiderate (不为他人着想的)? Being rude has become a point of pride for some. Talk to the Hand is a call for politeness.

    Alice Moore is a teenager entrepreneur (创业者), who in May 2015 set up her business AilieCandy. By the time she was 13, her company was worth millions of dollars with the invention of a super-sweet treat that could save kids' teeth, instead of destroying them.

    It all began when Moore visited a bank with her dad. On the outing, she was offered a candy bar. However, her dad reminded her that sugary treats were bad for her teeth. But Moore was sick of missing out on candies. So she desired to get round the warning, "Why can't I make a healthy candy that's good for my teeth so that my parents can't say no to it?" With that in mind, Moore asked her dad if she could start her own candy company. He recommended that she do some research and talk to dentists about what a healthier candy would contain.

    With her dad's permission, she spent the next two years researching online and conducting trials to get a recipe that was both tasty and tooth-friendly. She also approached dentists to learn more about teeth cleaning. Consequently, she succeeded in making a kind of candy only using natural sweeteners, which can reduce oral bacteria.

    Moore then used her savings to get her business of the ground. Afterwards, she and her father secured their first business meeting with a supermarket owner, who finally agreed to sell Moore's product-Cancandy.

    As CanCandy's success grows, so does Moore's credibility as a young entrepreneur. Moore is enthusiastic about the candy she created, and she's also positive about what the future might bring. She hopes that every kid can have a clean mouth and a broad smile.

    Meanwhile, with her parents' help, Moore is generally able to live a normal teenage life. Although she founded her company early on in life, she wasn't driven primarily by profit. Moore wants to use her unique talent to help others find their smiles. She donates 10% of AilicCandy's profits to Big Smiles. With her talent and determination, it appears that the sky could be the limit for Alice Moore.
