When describing people when should you use is and when should you use has?

"Is" is used for present-tense actions. It is used when describing what someone currently is like or is currently doing. For example, "She is going to the store." or "She is pretty." "Has" is past-tense. It is used to describe what people were previously like or were previously doing. For example, "He has been to the store already." or "He has been mean before." "Has" can also be used to indicate possession For example, "He has a nice smile."
