E-reading and e-books are slowly conquering the world. Compared to traditional paper books, e-books in some schools and universities attract more interest because the information flow seems much easier to manage and comes in a greatly higher quantity.

    Japan is known for the reform-minded attitude towards the gadget(精巧装置)world and for the fact that it is one of the first countries that encouraged in the educational system the emailing of homework.

    The digital textbook looks like the logical step in the world of learning. It is natural but it is also completely untraditional.

    The plan of the largest publishing companies to get in line with the trend is to save a large quantity of paper and make the kids become interested in learning using a cool gadget. Many USA universities and colleges have made students be used to the procedure of downloading the courses and of course the procedure involves interactive software and also the chance of using the computer.

    The traditional education system is still unwilling when it comes to giving up books. The standard approach of information taught out of a book and Shakespeare read out of an old school novel makes studying English as traditional as it can be.

    In a world where kids would rather see the movie than read a book, the digital age has brought along a completely different flavor to reading. Bringing that flavor in school will make teaching a greener and also a completely different matter.

    The iPhone, the iPad: each of Apple's products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i” --and many other brands are following suit. The BBC's iPlayer--which allows Web users to watch TV programs on the Internet--used the title in 2008. A lovely bear--popular in the US and UK--that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was started last week under the name “i”.

    In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce(电子商务) first came into use.

    Most “I” products are targeted at(针对) young people and considering the major readers of Independent's “I”, it's no surprise that they've selected this fashionable name.

    But it's hard to see what's so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King's College, London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn't have one clear definition(定义),” he says.

    “However, thanks to Apple, the term is now connected with portability (轻便).” adds Thorne.

    Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

    Along with “Google” and “blog”, readers of BBC Magazines voted “I” as one of the top 20 words that have come to define the last decade(十年).

    But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.

    Is it wrong—either grammatically or in terms of style—to mix the simple past tense with the past perfect in one sentence? To give an example, the following seems a bit heavy and awkward to me: "There had been a time when she had been happier.' I prefer: 'There had been a time when she was happier.' Any thoughts?

—ALEX

I think the second version is the correct one—it's shorter and clearer. Rather than focusing on tenses, focus on the clean, short sentence. If something seems heavy and awkward to you, the writer—then it probably is. Always short sentences.

    I have constructed texts for a range of children's picture books all based on working profession: bus driver, postman, footballer, cleaner, teacher, policeman to list a few. I've listed about thirty professions so far. I thought of titling them as Mr Bus Driver, Mr Postman and so on. Would I be infringing (侵权) the Mr Men titles if I did or should I think of something else?

—RAJIV

    The Mr Men stories are based on characteristics, not on jobs—Mr Lazy, Mr Noisy, etc—so they bear no relation to your projects. However, you will come under fire from gender equality supporters—every job you list could equally be done by a woman. No teacher and few parents would find work useful if it implies that all professions are open only to men. I advise you to look at modern children's books in a library or bookshop.

    Getting around in Canada is fairly easy. Most cities have urban transportation systems, including buses, streetcars, and trains, and some of the larger cities also have subways.

    You can board the transportation at regular stops along the routes. Some let you pay in cash, others require tickets. If you don't have a ticket for the bus, you must pay the right amount of money. This is because the driver does not carry any change. Once you get settled, you may want to buy a monthly pass or a package of tickets to save money. You can buy subway tickets at the subway station.

    If you have to take several buses or change subways on a single trip, you do not need to pay money each time. Simply ask the driver for a transfer, or pick one up from the machine on the subway platform.

    If you are not sure where to board the bus or the streetcar, just ask someone, or follow the crowd. It's usually at the front of the bus, where you show your pass to the driver. When using public transportation, Canadians line up. First come, first served, is a common approach to many activities in Canada.

    Maps of routes and schedules are usually available from the public transit company in your area, and there may also be a telephone information line. You may want to ask someone for the name of the transit company in the area where you live, and then look it up in your telephone book.

    The most popular martial arts (武术)today came from Asia, especially China. Some Chinese fighting styles were invented more than 3, 000 years ago. Many martial arts were invented because people needed to defend themselves or protect others. Nowadays, people learn martial arts as a way of keeping fit or as a competitive sport, but they are still very useful for selfdefence (防卫).

     Martial arts are often referred to as either soft or hard. These terms imply a way of dealing with your opponent's (对手的)force. Soft martial arts, such as tai chi, teach you to use your opponent's own force to defend yourself. Soft styles use movements and timing to avoid, deflect and redirect their opponent's attacks (攻击). These martial arts are soft for the defender but not for the attacker! On the other hand, hard styles, such as kung fu, teach you to defend yourself using force. Techniques involve blocking, posturing and powerful punching and kicking. Hard martial arts techniques are more effective(有效的)if you are more skillful, more powerful and faster than your opponent.

    Perhaps one of the best known Japanese martial arts today is karate. But did you know that it came from Fujian Province? in the century, a community of Chinese migrants(移民)from Fujian settled (定居)in what was then the kingdom of Okinawa. The Chinese migrants used to gather in a park to .enjoy cultural activities — one of which was kung fu. This soon caught the attention of local youths, who started learning kung fu from their Chinese neighbours.

    In fact, Chinese influence in martial arts was not only kung fu. The very first Korean military (军事)training manual was based on a Chinese version. During the Japanese invasion (侵略)of Korea in the 16th century, the Korean army needed an effective way to train a large number of soldiers. They used a training methodology from a Chinese military manual called ji xiao xin shu, written by the famous Chinese general, Qi Jiguang, who had himself defeated Japanese army.

    The term "smiling depression" —appearing happy to others while actually suffering depressive symptoms—has become increasingly popular. In fact, many people who experience a low mood and a loss of pleasure in activities manage to hide their condition in this way. And these people might be particularly easy to suicide.

    While smiling depression is not a technical term that psychologists use，it is certain to be depressed and manage to successfully mask the symptoms. The closest technical term for this condition is "atypical depression: It can be very hard to spot people suffering depression because they may seem like they don't have a reason to be sad — they have a job, an apartment and maybe even children or a partner. They smile when you greet them and can carry pleasant conversations. In short, they often put on a mask to the outside world while leading seemingly normal and active lives. Inside, however, they often feel hopeless and down, sometimes even having thoughts about ending it all.

    People with smiling depression put on a happy face to the outside world, but they can experience a lift in their mood as a result of positive occurrences in their lives. Other symptoms of this condition include overeating, feeling a sense of heaviness in the arms and legs and being easily hurt by criticism or rejection. They are also more likely to feel depressed in the evening and feel the need to sleep longer than usual. With other forms of depression, however, your mood might be worse in the morning and you might feel the need for less sleep than you are normally used to.

    So how can they break this circle? A starting point needs to be known that this condition actually exists and that it's serious. Only when we stop ignoring our problems because we think they're not serious enough can we start making an actual difference. Then we can find purpose by taking the attention away from ourselves and placing it onto something else. Feeling that our lives matter is finally what gives us purpose and meaning — and this can make a significant difference for our mental health and well-being.
