     Don't talk to me; I'm busy with my iPhone

     Riding a London subway, a person from China will notice one major difference: in London, people do

not look at each other. In fact, eye contact is avoided at all times. That's not rudeness-people are just too busy to bother looking.

     Busy doing what, you ask? Well, they're certainly not using the time for a moment of quiet reflection,

nor are they reading a book. New technology has replaced quiet habits. Today the only acceptable form

of book on the London underground is an e-book.

     Apple must earn a fortune from London commuters (乘车上下班的人). Since the launch of the

iPhone in 2007, over 40,000-yes, that's 40,000-"apps" (programs downloaded for the iPhone) have

been designed.

     Commuters love them because they are the perfect time-fillers. One "app", called iShoot, is a game

that features tanks. Another one, Tube Exits, tells passengers where to sit on the train to be closest to

the exit of their destination. ISteam clouds the iPhone screen when you breathe into the microphone. You

can then write in the " steam" on your phone screen.

     For those without an iPhone, another Apple product, the iPod, may be another choice. It's not just

teenagers who "plug in" to their music-iPods are a popular way to pass the time for all ages.

     And if games,  e-books and music aren't enough to keep you occupied. Then perhaps you would

prefer a film. The development of palm DVD technology means many commuters watch their favorite

TV show or film on the way to work. With all this entertainments, it's amazing that people still remember

to get off the train.
