PRESENT PERFECT CONTINUOUS



Present Perfect Progressive/Continuous

Present Perfect Progressive It is used to say how long someone has been doing something.
  • I have been studying English for 2 years.
  • I have been studying English since 1997.
  • It hasn't been raining for so long.
  • Have you been talking on the phone for the last hour?!?
Present Perfect Continuous


The PRESENT PERFECT CONTINUOUS expresses an action that recently stopped or is still going on. It puts emphasis on the duration or course of the action (not the result).

examples:
I have been studying present perfect continuous up to now.
She has been waiting at the bus stop since 5 o'clock.
Terry and Mary have been dating for a long time.

FORM

AFFIRMATIVE: S + HAVE/HAS + BEEN + VERB-ING
e.g. Gary has been playing soccer for a long time.

INTERROGATIVE: (WH-) HAVE/HAS + S + BEEN + VERB-ING?
e.g. Who has Laura been waiting for?
      Have the children been studying all this time?

NEGATIVE: S + HAVEN'T/HASN'T + BEEN + VERB-ING
e.g. Hailey hasn't been doing anything for hours.

TIP Remember that NON-CONTINUOUS verbs (BE, WANT, SEEM, NEED, CARE, CONTAIN, OWE, EXIST, etc.)cannot be used in any continuous tenses. So, instead of Present
Continuous, we must use Present Perfect.
e.g. Sheilas has been wanting that car for years. INCORRECT
       Sheila has wanted that car for years. CORRECT.
