Idont remember how to do simple and complet subjects and predicates

Simple Subjects:  is the main word or word group that tells whom or what the sentence is about.

Complete Subject: consists of all the words that tell whom or what a sentence is about.

Simple  Predicates: a verb, is the main word or word group that tells something about the subject.

A simple subject is what you are talking about not the whole subject like     
The bus is yellow and it has wheels.  What are we talking a about bus
So the simple subject is bus.  The complete subject is everything before the verb so the bus is your complete subject because the verb is is.  The predicate is the verb and everything after it so the predicate in this sentece is is yellow and haa wheels. If you still have questions just txt me!
HOPE THIS HELPS YOU ;-)
