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.

How teens can stay fit

    Any type of regular, physical activity can improve your fitness and your health.{#blank#}1{#/blank#}

    Exercise should be a regular part of your day, like brushing your teeth, eating and sleeping. It can be in gym class, joining a sports team, or working out on your own. Keep the following tips in mind:

    {#blank#}2{#/blank#} A good attitude is important. Find an activity that you think is fun. You are more likely to stick with it if you choose something you like. A lot of people find it's more fun to exercise with someone else, so see if you can find a friend or family member to be active with you.

    Take it one step at a time.{#blank#}3{#/blank#} For example, walk or ride your bike to school. Get on or off the bus several blocks away and walk the rest of the way. Use the stairs instead of taking the elevator.

    Get your heart pumping. Whatever you choose, make sure it includes aerobic (有氧的) activity that makes you breathe harder and increases your heart rate. This is the best type of exercise because it increases your fitness level and makes your heart work better.{#blank#}4{#/blank#} Examples of aerobic activities are basketball, running, or swimming.

    Don't forget to warm up with some easy exercises or stretching (拉伸) before you do any physical activity. {#blank#}5{#/blank#} It is also important to stretch out after you exercise to cool down your muscles.

A. Do the activity as often as possible, but don't exercise to the point of pain.

B. The most important thing is that you keep moving!

C. Make physical activity a habit.

D. Small changes can add up to better fitness.

E. Stay positive and have fun.

F. This warms your muscles up and may help protect against injury.

G. It also burns off body fat.

    Most people, when they travel to space, would like to stay in orbit (轨道) for a few days or more. And this stands to reason, if you're paying $ 20,000 for your trip to orbit! So in order for tourism to reach its full potential there's going to be a need for space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel—private rooms, meals, bars. But they'll also offer two unique experiences: impressive views—of Earth and space—and the endless entertainment of living in zero gravity—including sports and other activities that make use of this.

    The hotels themselves will vary greatly—from being quite simple in the early days to huge luxury (奢侈的) structures at a later date. It's actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven't expected the costs to come down far enough to make them possible.

    Lots of people who've been to space have described vividly what it's like to live in zero gravity. There are obviously all sorts of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don't need to sleep much living in zero gravity, so you'll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.

    Of course all good things have come to an end, unfortunately. And so after a few days you'll find yourself heading back to the earth. You'll be thinking how soon you can save up enough to get back up again-or maybe you should change jobs to get to work in an orbiting hotel!

    Your local grocery store is a psychological minefield (布雷区), where even the bananas are ripe with mystery.

    ⒈Southpaws (左撇子) have an invisible (看不见的) advantage

    You've probably seen that stores keep go-to items—produce, meats, dairy—on the outer edge. But did you notice that most of them are set up to make you run counterclockwise (逆时针)? Ninety percent of us are right-handed, so we buy more when it's counterclockwise. You'll also often find the dairy section in the back left corner：Because dairy is likely on your list, stores make sure you take the longest route to get there. In fairness, it's also a more convenient place to put a fridge.

    ⒉Everything is in its place

    It's safe to say that nothing you see on a shelf is there by chance. The cookies on sale at the end of a passage are likely the result of smart product placement. More expensive items are usually placed at an adult's eye level, while colorful treats and other products for kids are positioned lower—to catch the attention of children.

    ⒊Time goes by so slowly

    Stores rarely have windows or clocks. With no reference to the outside world, customers can easily lose track of how long they've been there so that they can buy more. Grocery stores may use another trick to control your sense of time: small floor tiles (瓷砖).

    Several Jobs That Will Be Automated By Artificial Intelligence(AI) And Robots

Translator

    Image recognition software and voice recognition software are bringing some major advances to language translation. Applications like Google's Word Lens can translate words from signs and documents in real time and there are a lot of translation apps that allow you to type in a word or phrase and will translate it for you.

    Some will even speak the phrase for you and raw word-to-word translation will be fully automated soon.

    Fast food workers

    Automated ordering booths have already made their way into a few McDonald's restaurants around the world, and cooking positions could be removed next. The booths probably can't handle customer service problems well, so televideo systems could bring in an office employee to deal with complaints.

    Field technician

    New advances in the Internet of Things could make this work obsolete.

    Low-cost sensors combined with high availability cellular／satellite communications and cloud technology are being started to automate and alarm these sites, and can be checked and maintained from a desktop or mobile device.

    Sales representative

    But, e-commerce is changing how we make purchasing decisions, especially those where there isn't much differentiation among the major competitors.

    If you're selling a high-differentiation product and／or a high-price, low-volume product you have some job security, but if you're selling a high-volume, low-differentiation product, you better start polishing your resume, said Doug Camplejohn, CEO of Fliptop. “These kind of product sales are all moving online.”

Films and computer games

    In just a few decades the gaming industry has become much bigger than the film business. What is called "interactive entertainment" makes more money than Hollywood cinema. Is there any way of making films more appealing to people who like to play computer games?

    Making a film out of a best-selling computer game can guarantee a large audience. {#blank#}1{#/blank#} Nowadays films are made with similar ones. They have attractive action scenes relying on fantasy effects as well. Gaming markets consist of science-fiction games, and film-makers have also set films in science-fiction worlds. {#blank#}2{#/blank#} Any attempt to borrow more than the setting from a game is certain to fail.

Why do gamers feel disappointed by films based on their favorite games? One of the reasons is technical. Now everything can be computer-produced. {#blank#}3{#/blank#} However, filming a scene from 20 different cameras would cost a fortune, so it simply isn't done in the film version—leaving the gamers feeling that the film didn't look as real as the computer game.

    {#blank#}4{#/blank#} In a film the director doesn't show you some things to keep you have the feeling of excitement or anxiety. For example, you wouldn't be interested in watching the film if you knew the identity of the murderer. But this is not true for computer games. When you play a game, you have to do certain tasks to continue to the new level. {#blank#}5{#/blank#} You are always in control as a player, while in the cinema you never control the action. You just sit and watch.

    There can be some interaction between films and computer games on different levels. For all the similarities between technologies and special effects, we shouldn't forget that a story and a game are fundamentally different.

A. Cameras matter in another sense, too.

B. The success of a game usually lies in the use of special effects.

C. You can't influence what happens at all in the computer games.

D. Computer games may show the action from a number of views easily.

E. The game has a good chance of being as successful as the film on which it is based.

F. You must be able to have access to all the information in order to decide what to do next.

G. However, the difficulty for film producers appears to be knowing where and when to stop.
