　　Some people can now no longer imagine life without their cell phones. The fact that theyare so popular proves that they are useful and convenient. Cell phones enable people toeasily and quickly communicate with one another; wherever you are, you can instantly reachsomebody.

Any new invention has its drawbacks, and such negativeaspects cannot always diminish its popularity. Despite the negative effects of television, forexample, the number of people who own televisions continues to grow at a tremendous rate.This is also the case with mobile phones. People won't stop eating just because of the riskofchoking. In addition, the swift development of science and technology will likely eliminatethe hazards cell phones may cause.
