"To be" Refers to when something will happen, or what something will be. It can also refer to something you wanted or expected to happen, but never did. Examples: "Next week, it's going to be my birthday." "The party is going to be great!" "That boy is going to be a great person." "I used to be faster." "I wanted to be there, but I couldn't make it." "I expect tomorrow to be better than today." "being" has three uses/meanings 1. It is used to explain what is currently happening to you, or what will/is happening to you while something else happens. Examples: "I am being attacked." "Where were you on Friday?" "I was being berated by John." "Now you are just being slow on purpose..." 2. Used as a synonym for "person" is specific circumstances. This is only used in stylized writing or conversation. Examples: "He is a cold hearted being." Meaning that he is an unkind person. "She was a sorrowful being." Meaning that she was a sad or grieving person. 3. "being", along with the idiomatic phrases "whole being" and "all of [pronoun] being", refers to all of your skill, emotion, thought or soul. Examples: "Basil put his whole being into the painting." "John wanted to win with all of his being." "I'm a face in the crowd, my being has left me." This was a good question. I had to think quite a bit to answer it haha. Good luck!

Examples: It's currently 'being' tested Jack is going 'to be' 16 tomorrow.
