When we smile, our system recognizes that there’s an absence of threat, and relaxes: It slows down our heart rate, and may temporarily reduce blood pressure, too, promoting overall heart health. Even forcing your face into a smile can reduce stress and relax your heart rate.

Smiling is a language that everyone understands regardless of age, race, culture, language, and nationality. We all know that when you smile at people, even strangers, they almost always smile back, spreading a kind of peace and goodwill. This contagious(有感染力的)smiling comes from a subconscious tendency to match other people’s emotions. It’s why people who spend time around children,who smile often, naturally smile more than people who keep mostly adults company.

People who are generous with smiles are considered more likeable and approachable than people who wear a deadpan(面无表情的)expression. Consider successful salesmen and politicians. Can you imagine how we’d react if they wore sour expressions? People who smile a lot are more likely to gain our trust — and earn better tips — than someone who provides the same service with an impassive face.

In a study, Major League Baseball players from 1952 who wore full-faced, genuine smiles on their baseball cards lived longer, around 79.9 years, compared to players who only partly smiled or didn’t smile at all, who lived 5 to 7 years less. Smiling can make us look younger, too: People who smile frequently seem to age more slowly, appearing around three years younger than their less smiley counterparts.

We now have evidence that we are hardwired to smile. While smiling used to be considered a learned behavior that babies acquired at around six weeks of age, more advanced ultrasound testing has shown that even babies who are bom blind can smile. Babies have been known to make breathing and sucking movements while still in the womb(子宫), and these reactions are thought to prepare them for their life outside. Now smiling has joined the list. Say cheese!

When important events are happening around the world, most people turn to traditional media sources, such as CNN and BBC for the news. However, during the war in Iraq in 2003, many people followed the war from the point of view of an unknown Iraqi citizen who called himself "Salam Pax" (Salam Pax means peace).

Salam Pax wrote a diary about everyday life in Baghdad during the war, and posted it on his website. Pax's online diary was a kind of website known as a "blog". Blogs are online diaries, usually kept by individuals, but sometimes by companies and other groups of people. They are the fastest growing types of website on the Internet.

A blog differs from a traditional website in several ways. Most importantly, it is updated much more regularly. Many blogs are updated every day, and some are updated several times a day. Also, most blogs use special software or websites, which can help ordinary people easily set up and start writing their own blogs.

There are many different kinds of blogs. The most popular type is an online diary of links where the blog writer surfs the Internet and then posts links to sites or news articles that they find interesting, with a few comments about each one. Other types are personal diaries, where the writer talks about their life and feelings. Sometimes these blogs can be very personal.

There is another kind of blogging, called "moblogging", short for "mobile blogging".

Mobloggers use mobile phones with cameras to take photos, which are posted instantly to the Internet. The use of mobile phones in this way made the headlines in Singapore when a high school student posted a movie he had taken of a teacher shouting at another student on the Internet. Many people were shocked by what the student did, and wanted phones with cameras to be banned from schools.

Many people think that as blogs become common, news reporting will rely less on big media companies, and more on ordinary people posting news to the Internet. They think that then the news will be less like a lecture, and more like a conversation, where anyone can join in.

The days of glancing at a map or the screen of your smart phone when you’re lost will soon be over, thanks to new shoes that tell you which way to turn to. The shoes use a Bluetooth link to communicate with your mobile’s mapping system. The mobile works out which route you should be following and the shoes then produce a slight shaking in either foot telling you when and where to change direction.

The shoes will also count the number of steps you’ve taken and the calories you’ve burned, and they’ll even buzz to warn you you’ve left your phone behind, or to tell you when you’re travelling past an interesting landmark.

“They are as easy to use as a tap on the shoulder,” said Krispian Lawrence, 30, who developed the shoes with partner Anirudh Sharma, 28, in Hyderabad, India. “You can even communicate with them using hand gestures and finger snaps because the shoes have sensors that can pick up movement and sound.”

The Lechal shoes go on sale worldwide in June but Lawrence and Sharma’s company, Ducere Technologies, has already taken more than 3,000 pre-orders. Lawrence believes the shoes will also improve road safety. “If I’m on my bike or motorbike, I don’t want to stare at my phone ---it’s dangerous,” he says. “I’d rather be guided by my footwear.” He believes his invention will prove invaluable for the visually impaired and has promised that every mainstream pair sold by Ducere will subsidize(资助) a cheaper pair for a visually damaged person.

Footnav technology does not impress explorer Sir Ranulph Fiennes, however. “What’s wrong with a good old-fashioned map?” said the 70-year-old when told of the shoes. “If you rely too heavily on technology, you’re heading for trouble. Too many people have forgotten the basics: how to read a map and a compass.”

A. Positive B. Negative.

C. Disturbing. D. Confused.
