Dictionaries often define the meaning of verbs as : to apprehend, to look around, to be aware of, or to be capable of .... And I often ignore the 'to.' Treating them as they are just there to fill the blank. But problem is, when adjectives follows 'to + be,' it comes to my mind that it means 'become (aware of),' today I saw a definition showing 'to be [adjective] or become [adjective].' It seems like 'be' is considered to designate 'a sate' and 'become is considered to designate 'change of a state.' That somehow sounds like 'to be adjective' construction is used only to describe the state, not the action, which sounds like an adjective. 'He can be careful' 'Be careful' 'She should be careful' This kind of sentences is harder to comprehend with such sense. With difference with 'become' in my mind, I can't really understand the meaning without using 'become.' Can anyone help me figure out?

"To be" is a linking verb used in constructions like: He is a teacher. He is good. Certain verbs also function like a linking verb: He became a teacher.
