Nowadays，with the rapid development of IT and information industry， cell phones play a dominant role in towns people's life。 But， like everything else， they have both favorable and mffavorahle aspects。
First， it's useful。 As a wireless mobile telephone， it's easy and handy to early to wherever one goes and call the callee however far away he is。 Therefore， it greatly facilitates people's life。 Second， it's convenient。 Whenever one meets trouble or something urgent， one can nmke a call immediately。 Most important of all， it's a very helpful panion。 With a multirfunction cell phone in hand， one can easily get on the Net， browsing the useful information， conducting e-merce and doing whatever one can do via Internet。
However， just as everything has two sides， the cell phone also has many disadvantages。 To begin with， it's expensive to buy and costly to pay the hills， esp。 that of global service。 To make matters worse， it's also easy to lose and costly to get it repaired。 Worst of all，it's not as clear as a family telephone and sometimes the number dialed is often not available。 Last but not least， it's alleged the microwaves in it might do harm to people's health。
In my opinion，with its expenses greatly reduced after China's entry into the WTO， it will face an ever brighter future in its development。 Someday most of them will be developed into new Intemet-enabled mobile phones， which will be as useful as pocket puters。 And I believe its advantages will not only offset its disadvantages， but also far outweigh them。
Cell phones have bee increasingly popular in china these days。 wherever you go you can see people using cell phones。 many college students， even high school students， have cell phones。
Cell phones have brought people a lot of benefits， but the most important is that they are convenient。 with cell phones in their hands， they can keep in touch with anybody they want。 if they want to get some information from the internet， they can easily have their dream realized via cell phones too。 furthermore， if someone has a heart attack or a traffic accident， a call to emergency hospital or to the police can quickly bring him the help he wants。
However， cell phones can also bring people problems。 the most serious is the electric wave radiation which is thought to be harmful to users' brains。 another problem is that when people are having a meeting or having a class or at a concert etc， the ring of the cell phone may interrupt others。 so i think people should use cellphones as little as possible and turn them off when they are attending important meetings or attending classes。
In recent years there has been a dramatic rise in the cell phones， which are now essential to millions of people as a convenient form of munication。 In 2019 the number reached 315，000，000， with an average annual increase at 57，500，000。 ?
Some people can now no longer imagine life without their cell phones。 The fact that they are so popular proves that they are useful and convenient。 Cell phones enable people to easily and quickly municate with one another; wherever you are， you can instantly reach somebody。 Cell phones eliminate thetrouble of not being able to meet someone in person， and therefore increase business's efficiency。 ?
