Most of the ATC instructions follow specific patterns. You just need to get familiar with the patterns and routines. Say Again, Please is a great book on the different scenarios.
This is very good, but really targeted towards power pilots more involved with ATC. https://www.amazon.com/Say-Again-Please-Guide-Communications-dp-1619547740/dp/1619547740/ref=dp_ob_title_bk
What are you concerned about? Uncontrolled airports just need announcements of position and intent. Towered airports will expect you to follow their directions, which may be impossible. You'll have to explain what you need if you land at one.
This was a good starting point for me: https://www.amazon.com/Say-Again-Please-Guide-Communications/dp/1619547740/
the one good thing a terrible instructor I had told me was to read the book, "say again, please"
