【正确答案】[参考范文]
As we know, the real name system of mobile phones was officially put into effect. Some people are quite in favor of it. However, there are also many people who are against it. As far as I am concerned, I extremely agree to this practice.
Undoubtedly, mobile phone has become an indispensable part in our daily life. Not only has it brought us so many conveniences but also has transformed our life and our means of communication. However, just as the proverb goes, every coin has two sides, there is no exception to it, mobile phone has caused us some serious problems because more and more criminals of mobile phone make use of it to cheat, to transmit rubbish messages such as pornographic messages, private affairs and even country's confidential information. Obviously, it seriously influences our normal life and country's security as well. Therefore, it is necessary for the government to carry out the real name system of mobile phone.
Based on what has been analyzed, we may reasonably reach the conclusion that mobile phone not only brings us some advantages but also causes us some disadvantages. Generally speaking, its benefits are far greater than its harmful effects. Only through the real name system can we settle this controversy/argument effectively.
