I think the most important invention of technology is cellphone.When i was young, I remember that everytime when I wanted to call somebody, I had to go back home, because the homephone stay at home. with the developing of technology, when I entered in to middle school, more and more people started to get a kind of small phone, they could put it down in the bag, when they wanted to use it , just took it and called someone. Gradually, there were many new modle of the cellphone were inviented and the function has become more and more stonger. Expecially some company depended on people's different characters making a lot of accessories. the cellphone gives people a conivence way to communicate with each other. we do not need to pay a lot of money and we do not need to worry about where are you living, if you miss someone or want to talk with some one, just call him/her. In conclusion, the cellphone absoulately is the best and most important invention in my life. I like it and I enjoyed using it everyday. I can not imaginae that how can I live without cellphone.
