Once you have found the main subject and main verb for each sentence, you should be able to tell which words go with the subject (that will tell you what the complete subject is) and which words go with the verb (that will tell you what the complete predicate is). With most sentences (but not all), you can draw a line in front of the main verb; then the complete subject is in front of that line, and the complete predicate is after that line.

Jane / saw the ball game.

My Aunt Sally / went shopping yesterday.
