I am trying to muster(鼓起)the courage to toss away my mobile phone to enjoy a more peaceful and ring –free life． Can you imagine not having your mobile phone? In our high-tech, in-a-hurry age, a cell-free 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, e-mail 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 cell, “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 dicided not to serve my mobile phone． Like all machine, I can always turn it off． 1．What does the underslined phrase“toss away”mean?
