     Collecting mid writing news is like researching in history:the best information comes from

those who were there at the time.So if we want to study the history of China in the sixth century

AD,we look at the writings of the people who lived then.They are called the primary sources

because they tell us what it was like to live then.People at a much later date who write about

the same events are called the secondary sources.For example,when we read the original writings

of Jia Sixie on agriculture,we are reading a primary source;when we read about Jia Sixie in our

textbook we are reading secondary source because the passage was written about him and his ideas

many years after he died.

     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.
