When we make news we use primary and secondary sources.We can see this most clearly in TV programmes.As we watch the news on TV,the person presenting the programme in the studio is the secondary source (because he tells us about the news)and the reporter in Iraq or Washington is the primary source(because he is telling us about what is actually happening there).Without these reporters acting as primary sources,you would never find out what really happened in a war,earthquake,sports meeting,concertor festival.These reporters explain what is happening so we have a clearer idea of what is going on there.They often take photographers with them who act as primary source by giving pictures of events.

　　In a newspaper the position is different because these two roles are often combined.This means a reporter who investigates a story may be the same person who writes it.If this happens,the reporter is both the primary and the secondary source.But the photographer who works with him/her is still a primary source.

　　One of the reasons that it is important to separate primary and secondary sources is that they help us to decide what is a fact and what is an opinion.A fact is something that everybody agrees has happened.An opinion is somebody’s idea of what happened.So facts and opinions are often mixed in any report,whether in a newspaper or on TV.
