IMPORTANT
Remember that the Present Perfect Continuous has the meaning of “lately” or “recently.” If you use the Present Perfect Continuous in a question such as “Have you been feeling alright?”, it can suggest that the person looks sick or unhealthy. A question such as “Have you been smoking?” can suggest that you smell the smoke on the person. Using this tense in a question suggests you can see, smell, hear or feel the results of the action. It is possible to insult someone by using this tense incorrectly.
