                                                          Searching for the Truth
     Collecting and 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 a 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, concert
or 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.
     What have you learnt from the above passage?
Primary source Primary sources are the writings of the people who lived at   1   time and offered an
inside view of a particular event.
Secondary source Secondary sources are the writings of the people who write about the same events
at a much later date with explanation and analysis   2   on primary sources.
News on TV The TV  3  in the studio is the secondary source while the reporter on the   4   is the
primary source.
News in a newspaper A newspaper reporter can be both primary and secondary source if he collects
the information and then   5   the news. But the photographer   6   with the
reporter is always a primary source.
FactA fact is something that everybody agrees has happened. In other   7    , it is
something that is   8   .
OpinionAn opinion is somebody's idea of what   9   on.
Conclusion Primary and secondary sources are both important for  10  the truth.
