my favorite lesson from english was about predicate nomnitive case--(do you remember it? i do!

sing to the tune of yankee doodle:
Be, Seen, Feel, Become, Appear,
Look, Taste, Grow, Sound, Remain, Smell,

Copulative Verbs take Nomative,
Predicate nouns or Adjectives

singing (under my breath!) that list of works, got me through many a state wide test.. (Which Sentence has a predicate noun? --the one with Be, Seen, Feel... would always be my first choice (and usually the right one!))

(and some, (um, lets just say a lot of years!) later, i still know them!
