| Present Perfect Continuous [color=#ad0a22]FORM Present Perfect Continuous
[HAS / HAVE] + [BEEN] + [VERB+ing]
EXAMPLES:
I have been waiting here for two hours.
She has only been studying English for two years.
NOTE: When you are using a verb tense with more than one part such as Present Perfect Continuous (has been studying), adverbs often come between the first part and the second part (has only been studying).
USE 1 Duration from the Past Until Now
We use the Present Perfect Continuous to show that something started in the past and has continued up until now. "For five minutes", "for two weeks", and "since Tuesday" are all durations which can be used with the Present Perfect Continuous.
EXAMPLES:
They have been talking for the last hour.
She has been working at that company for three years.
James has been teaching at the University since June.
USE 2 Recently, Lately
You can use the Present Perfect Continuous WITHOUT a duration such as "for five minutes", "for two weeks", and "since Tuesday". Without the durations, the this tense gives a more general meaning of "lately". We often use the words "lately" or "recently" in the sentence to strengthen this meaning.
EXAMPLES:
Recently, I have been feeling really tired.
She has been watching too much television lately.
Mary has been feeling a little depressed.
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 suggests that the person looks sick or unhealthy. A question such as "Have you been smoking?" suggests that you can 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.
IMPORTANT Non-Continuous Verbs/ Mixed Verbs
It is important to remember that Non-Continuous Verbs cannot be used in any continuous tenses. Also, certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses. To express the idea of Present Perfect Continuous with these exception verbs, you must use Present Perfect.
EXAMPLES: Sam has been having his car for two years. Not Correct
Sam has had his car for two years. Correct
ACTIVE / PASSIVE Present Perfect Continuous
EXAMPLES:
Recently, John has been doing the work. ACTIVE
Recently, the work has been being done by John. PASSIVE
[color:364a=#ad0a22:364a]NOTE: Present Perfect Continuous is rarely used in its passive form.
