When Scotsman Alexander Graham Bell invented the telephone in 1876, it was a revolution in communication．Over the last two decades a new means of spoken communication has emerged: the mobile phone．

The modern mobile phone is a more complex version of the two-way radio．Traditional two-way radio was a very limited means of communication．As soon as the users moved out of range of each other's broadcast area, the signal was lost．In the 1940s, researchers began experimenting with the idea of using a number of radio masts （天线杆）located around to pick up signals from two-way radios．A caller would always be within range of one of the masts; when he or she moved too far away from one mast, the next mast would pick up the signal．（Scientists referred to each mast's reception area as being a separate "cell"; this is why in．many countries mobile phones are called "cell phones"．）

The first real mobile telephone call was made in 1973 by Dr Martin Cooper．As soon as his invention was completed,, he tested it by calling another scientist to announce his success．Within a decade, mobile phones became available to the public．They have changed the way we do a lot of things．One powerful feature is the Short Message Service （SMS） or text message．It's the perfect communication method for the busy modern lifestyle．Going to be late? Send a text message! The text message has changed the way we write in English．The language construction became less strict．Traditional rules of grammar and spelling are much less important when you're sitting on the bus, hurriedly typing "Will B 15mm late-C U @ the bar．（I will be 15 minutes late to see you at the

bar．） Sorry!"．

Over the last few years mobiles have become more and more advanced．We have seen the instruction of cameras, global positioning system and Internet access．

Alexander Graham Bell would be surprised if he could see how far the science of telephone has progressed in less than 150 years．If he were around today, he might say: "That’s gr8（great）! But I'm busy rite now（I am very busy right now）．Will call U2nite（I will call you tonight．）．"
