《安全生产法》规定生产经营单位的安全生产管理人员的职责是什么？

Many cities have subways and underground public transportation to take locals and tourists alike rapidly around the city．However, there’s something different about riding a London subway．It may not look different, but the historical value of one of England’s most popular forms of transportation is enough to make riding the subway a must when visiting London．With a little under 300 different stations, the subway can take you almost anywhere you need to go．

Riding a London subway, a person from other countries 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 thinking．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（使用月票上下班者）．Since the launch of the iPhone in 2007, over 40,000―yes, that’s 40,000 “apps” 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 the distraction（消遣）of 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 shows or films on the way to work．With all these distractions, it’s amazing that people still remember to get off the train．
