Believe it or not, cell phones have been around for over a quarter of a century.The first commercial cell phone system was developed by the Japanese in 1979. But cell phones have changed a lot since that time. The early cell phones appeared big and heavy but they have developed into small and light palmsized models. There have been huge developments in their functions，too. We have had call forwarding, text messaging, answering services and handsfree use for years, but now the manufacturers equip countless new facilities, such as instant access to the Internet and receiving and Sending photos.
Cell phones have become very common in our lives；recent statistics suggest as many as one in three people on the planet now has a cell phone, and most of them say they couldn't live without one. Cell phones are used in every area of our lives and have become a necessary tool, used for essential arrangements, social contact and business. They have made it easier to call for help on the highway. They have made it possible to keep in touch with people “on the move” when people are traveling.
Cell phones have made communication easier and have reduced the need for family arguments. We can use cell phones to let our family know we'll be late or if there's a change of plan or an emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late, and they can now contact their children at any time.
This does not mean that cell phones are all good news. They have brought with them a number of new headaches for their owners: it costs a lot to replace stolen phones, something that is becoming a frequent occurrence, and have you ever seen such huge phone bills? More serious, however, is the potential health problem they bring: there are fears that radiation from the phones may cause brain tumor(肿瘤). This may be a time bomb waiting to happen to younger people who have grown up with cell phones that they simply can't live without.
(2013·江西九校高三联考)One fine afternoon I was walking along Fifth Avenue，____ I remembered that it was necessary to buy a pair of socks. Why I wish to buy only one pair is ____. I turned into the first sock shop that ____ my eye, and a boy clerk who could not have been more than seventeen years old ____. “What can I do for you, sir？”“I wish to buy a pair of socks.”His eyes glowed. There was a note of ____ in his voice.“Did you know that you had come into the finest place in the world to buy socks？” I had not been aware of that, as my entrance had been ____. “Come with me，” said the boy，excitedly. I followed him to the back part of the shop, and he began to haul down from the shelves box after box，____ their contents for my enjoyment.
“Hold on, young man, I am going to buy only one pair！”“I know that，” said he，“but I want you to see ___ beautiful these are. Aren't they wonderful？” ____ was on his face an expression of solemn and holy pleasure，____ he were revealing to me mysteries of his religion. I became far ____ interested in him than in the socks. I looked at him in amazement. “My friend，” said I, “if you can keep this up, if this is not ____ the enthusiasm that comes from novelty, from having a new job, if you can keep up this enthusiasm and excitement day after day, in ten years you will own every ____ in the United States.”
My amazement ____ his pride and joy in salesmanship will be easily understood by all who read this article. In many shops the ____ has to wait for someone to wait upon him. And when ____ some clerk does notice you, you are made to feel as if you were interrupting him. Whether he is ____ in deep thought in which he hates to be disturbed or he is chatting with a girl clerk, you feel like ____ for “being too rude”．
He displays no interest either in you or the goods he ____ to sell. Yet possibly that very clerk who is now so apathetic began his career with hope and ____. The daily grind was too much for him; the novelty wore off; his only pleasures were found outside of working hours.
