17．Could you get away from t he Internet today and not go online again for 12 months？For many of us，the answer is probably an emphatic"No!"-the Internet has become part of our life and we have a hard time without it．But Paul，a 26-year-old writer at The Verge，a technology website，just did the seemingly impossible：he survived a year without the Internet．
Beginning on Oct.30，2011，he didn't read e-mail，type a word into Google or download a single app．He lived his entire year offline in hope of finding out more about himself and focusing on other activities．But on November 1，2012，Paul turned on the Wi Fi on his laptop and i-Pad．
"I was wrong，"he began．His article is titled"I'm still here：back online after a year without the Internet．"At first，the was encouraged to"stop and smell the flowers by a new friend he made at the beginning of his Internet-free adventure"．And that is what he intended to do．He described the first months of 2011 as full of surprising events：real life meetings，bike rides and reading．Besides，his relationships with his family got closer．He visited his brother's family instead of using Facebook to communicate with them．
But as the months went by，Paul"had learned how to make a new style of wrong choices off the Internet"．The learning and creativity turned into social retreat（隱退）．Instead of reading and writing，he started playing video games for hours on his sofa．He missed some of his Facebook and long-distance friends．"I fell out of the flow of life．"he wrote，"The experiment was a failure．My plan was to leave the Internet and therefore find the‘real'Paul and contact the‘real'world，but the real Paul and the real world are always connected to the Internet．Not to say my life wasn't different without the Internet，jus that it wasn't real life．The Internet is where people are．"
