Ten years ago few people had mobile phones.But now mobile phones have become rather common , even high school students may have one . But is that a good thing ? We wondered . It gose without saying that mobile phones bring us much benefits , such as chating wherever we`re , getting and sending emails , taking photos , playing games and so on . And if we come across emergencies , it will turns out to be very helpful . In other hand , it`s a big attraction to we high school students . It may have bad influence on us .After all , mobile phones have changed our life , and still will too. We must use mobile phones reasonably , and it`s the most importent and ecessary.
