the past, but is still happening today.

2) The Present PerfectContinuous Tense

The present perfect continuous is oftenvery similar in meaning to the presentperfect tense.

Just like the Present Perfect, we can usethis grammar to talk about something thatstarted in the past, but is still happening.

But the present perfect continuous focusesmore on the continuous action.Theemphasis is on the durationof the action.

hallway. Theyhave been talking

since class ended.


15/20

Note! In English, we dont usually use stative(non-action) verbs with continuous tenses.

Example:Jean got a headache two hours ago.She still has a headache now.

Because have is a stative verb, we dontlike to put it in continuous form; soinstead, we use present perfect:

Jean has had a headache for two hours.

She has been having a headache for two hours.

Review:1. The Present Perfect and the PresentPerfect Continuous can be often be used inthe same circumstance.

Example:1) I have taughtat ECC for many years.-present perfect2) I have been teachingat ECC for many years.

-present perfect continuous

-In this case, both actions started in the pastand continue up to the present time.

Review:

2. However, we DONT use the PresentPerfect Continuous with stative(non-action)verbs; instead, we prefer to use the

Present Perfect.

Example:1) I have been knowingMaria for many years.

-INCORRECT

2) I have knownMaria for Many years.

-CORRECT
