阅读理解

     I am trying to muster (鼓起) the courage to toss_away my mobile phone to enjoy a more peaceful

and ringfree life.

     Can you imagine not having your mobile phone? In our hightech,  inahurry age,  a cellfree life is a hard

concept to swallow.Our mobile phones can now access the Internet,  and many people feel the need to

express their every thought on their blog pages.If I gave up my cellphone,  people would think I was mad.

     I wish I had the strength to toss away my technology.I have an office phone,  a home phone,  an email

and if people want to contact me,  they can.If I'm out,  people can leave a message.Do they really need

to find me 24/7?However,  I'm a bit like Frodo in the movie Lord of the Rings.The power of the ring is

too strong and I can't let it go.

     Mobile phones have become necessary tools in our busy life.For most people,  they hold all contacts

and many of us don't write up address books any more.The latest phones carry our music,  pictures, 

 movies and everything else.We feel lost without this device and when we do misplace it,  we feel cut off

from our fellow.

     "Where have you been?" said a friend,  who saw me a week after I lost my cellphone,  "I tried calling

you,  but you disappeared.You disappeared off the face of the Earth." See,  when you don't have a

mobile phone,  you don't exist.

     I'm not really going to toss my mobile phone away,  in fact.We humans are such social animals and

mobile phones serve us well.So in 2009,  I've decided not to serve my mobile phone.Like all machines, 

 I can always turn it off.
