Present Perfect Continuous

The present perfect continuous places the emphasis on the duration of a current activity. It is used to express either when an action in progress began, or the length of an action in progress. The present perfect continuous is never used with stative verbs.

Example:

He hasn't been spending the earnest money this month.

How long have your net assets been dwindling?

I've been typing a note for all bank workers about the provision of uniforms since nine this morning.

Positive Form:

Subject + have + been + 'ing' form of verb + (object(s)) + since / for + time expression

They've been talking about convertibility of funds ever since dawn.

Negative Form:

Subject + have + not + been + 'ing' form of verb + (object(s)) + since / for + time expression

She hasn't been maintaining the accounts on behalf of the shareholders.

Question Form:

(Question Word) + have + subject + been + 'ing' form of verb?

Examples of What Caused Something

The present perfect continuous is often used to express the action that caused a present result.

Example:

I've been working on the appraisal since six this morning. That's why you have it already.

Present Perfect Contrasted with Present Perfect Continuous

The present perfect and present perfect continuous are both used to express the duration of an activity that begins in the past and continues into the present. Either form is used with general activities, although the use of the present perfect continuous can indicate that an activity is about to change. The present perfect continuous describes the duration of a current activity and tends to be used with more specific action verbs.

Example of Present Perfect:

Rick has been in the branch twice to offer collateral on his loan.

The money market hasn't been very good since 2008.

Example of Present Perfect Continuous:

The client hasn't been willing to discuss earnest money all week.

They've been talking about convertibility of funds ever since dawn.

When emphasizing the duration of the current action, use the present perfect continuous.

Example:

Real estate has been plunging steadily for the last year.

We've been discussing who is to be held responsible for this for an hour.

The present perfect continuous conveys the length of an activity, whereas the present perfect can also be used to relate the quantity, or amount finished up to the present moment in time.

Example:

The cash cow product has done well considering the economy.

I've prepared three documents to transfer power of attorney this week.
