+
+In English, when making introductions or identifying someone, you use the verb `to be`. In this case, `You are` is used to address the person Maria is talking to and affirmatively identify their occupation.
+
+Maria is introducing herself and confirming Tom's job role. `Are` is used in the present affirmative to make a statement.

+
+The verb `to be` is an irregular verb. When conjugated with the pronoun `you`, `be` becomes `are`. For example: `You are an English learner.`
