The study discussed the representation of risk of Electromagnetic Wave in 2005-2006 print media, and taking approach of language-pragmatism to analysis the similarity and diverseness in different situations of news discourse.
We found that media constructed more the picture of risk of Electromagnetic wave in demonstration-field, in these news, journalist were inclined to choice schema of simple and common sense for audience, like story of distress etc, implying its danger. In life and consumption field, appearing more defensive word on news discourse, like "resistant", "proof" etc. Implying danger are the same.
Owing to the risk of Electromagnetic Wave are vague in the world, and rational science didn ’t has accord explanation with itself. So media always constructed represent common sense –like "Better to be sure than sorry", showing Electromagnetic Wave as hazard and danger to people.
