Write any good report of your choice (high school level)
The introduction is meant to introduce the reader to your field of study. Its common to start writing in quite general terms to get an uninitiated reader interested in your field of study.
Therefore it is good idea to start with something interesting, that will draw the reader further into what you will eventually write about. Think about you first thought was interesting about the subject before you started writing your report properly.
Even though a introduction is the first part of any good report, its usually not a good starting point. To write an interesting introduction its usually better to wait until a later point when you know more about the subject and research connected to it.
