LI.To identify a main verb of a sentence.

This week me and my group had learnt about verbs,subject and object.What we had to do was that we had to make a sentence about a main idea like My mother and use that word to put it with another word like this Mr mother left me at home.I learnt with Mr wong he told me to have thus quetion in my head so i could finish my work faster and the question was who did the action which is the subject.
