As the development of internet,the network language has been used more and more frequently.However,in my opinion,the network language should not be used oficially.Now I have several reasons for this viewpoint.Firstly,the language can be used on an official occasion should be standard,such as Putonghua in China and English in America,and etc.People say proper language,do proper actions on a special occasion.Secondly,there is no one who act at will on a officail occasion.So we also should say proper words or officail sayings when we intend to express ourselves.The network language surely seems informal.
Thirdly,sometimes the network language can not interpret the specific or even the correct meanings.
