Be: Be is a linking verb, it links a subject and the thing connected to the subject. examples: Sarah want to be a doctor when she grows up. (Sarah is the subject and doctor is what is being connected to Sarah) Being: Being is mostly used as a present tense examples of sentences with being: Lany's little boy is a rude being. (not exactly present...) Being human is not as good as being divine. She is being mean to me. (present tense) I hope this helps.
