Present perfect continuous

Your hands are covered in paint. What have you been doing? The present perfect continuous connects an earlier activity with now.

Form and main uses

Use have/has + been + verb-ing:

• I’ve been painting the kitchen.
• She hasn’t been sleeping well.
• Have you been waiting long?

This form often shows that an activity started earlier and is still happening: We’ve been studying for two hours. It can also describe an activity that has just stopped but has a visible result: The ground is wet because it’s been raining.

Follow the activity up to now

Suppose you start studying at nine and it is now eleven:

9:00 — start studying → two hours of activity → 11:00 — now
I've been studying for two hours.

You might still be studying, or you might have just taken a break. The form presents a recent or continuing activity; context tells us whether it has stopped.

Compare I'm studying. This places us inside the activity now, but does not tell us how long it has been happening. I've been studying since nine adds the earlier starting point and connects it to now.

Keep the three parts together

Have/has agrees with the subject. Been stays the same. The activity ends in -ing. Do not write has been learn or has learning: both omit a needed part.

For spelling, compare work → working, write → writing and run → running. You normally drop the final silent e and sometimes double a final consonant.

A question word comes before the auxiliary: What have you been doing?; How long has she been waiting? The subject stays between have/has and been.

Activity or completed result?

Compare these two sentences:

• I’ve been writing emails all morning. The focus is the activity and its duration.
• I’ve written six emails this morning. The focus is the completed number.

The continuous form does not tell us by itself whether the whole task is finished. If you need to say how many things were completed, the present perfect simple is usually clearer.

For and since

Use for with a duration and since with a starting point:

• He’s been practising for an hour.
• He’s been practising since nine o’clock.

Some verbs describe states rather than activities. With know, own and believe, use the simple form: I’ve known Ana for years, not I’ve been knowing Ana for years.

Explain the evidence you can see

A: Your shoes are covered in mud!
B: I've been walking by the river.
A: Have you finished your walk?
B: Yes, I've just got back.

The continuous explains the muddy shoes. The final line tells us the walk has ended. Without it, I've been walking alone would not tell us whether the whole walk was finished.

The tense also describes repeated recent activity: I've been looking for a new flat this week may include several searches, not one uninterrupted search. She has been calling me every evening describes a recent repeated pattern.

Choose what you want to measure

I've been reading this book for an hour measures the activity. I've read forty pages measures the completed amount. With a number of finished items, the simple form is usually clearer: I've answered five questions, not I've been answering five questions if you mean five completed answers.

For a continuing activity, both forms can sometimes work: I've waited for twenty minutes and I've been waiting for twenty minutes. The continuous makes the ongoing wait more prominent. It is not necessary to mark the simple version as wrong.

For states, use the simple perfect: I've had this bike for years and I've known Jo since school. The distinction is about the meaning of the verb and the focus of the sentence, rather than a rule that for always requires a continuous tense.

If the reference point is a finished past event, use a past tense instead: I studied for two hours yesterday. The present perfect continuous looks back from now, so I've been studying yesterday is not the normal choice.
