V. Action and Time in the Perfect Continuous Tenses: Past, Present and Future

1.0 Past

We may also use the Perfect Continuous Tense in the Past. However, unlike the Past Perfect Tense, which basically functions in the same way in the Present and Future Perfect, the Past Perfect Continuous Tense is different from the Present and Future Perfect Continuous Tenses.

When we use the Past Perfect Continuous tense, it usually implies that the action stopped in the past (just like the Simple Past Tense).  In this case, the use of the Past Perfect Continuous Tense usually implies that the action was expected to continue past an end point, but it did not, opposite to expectations.

Example

I had been studying for 3 hours when my friend called. He wanted to play basketball, and I decided to join him.

2.0 Present

The action started in the past and continues until the present, even if the present is not mentioned. In this case, it is implied; however, in the Perfect Continuous Tense, the action is expected to continue past ‘now’.

Examples

I have been studying since 7:00 a.m..  (until now—expected to continue)
I have not been studying for 3 hours.  (until now—expected to continue for a while)

3.0 Future

The action started at a point prior to the end point and continues until the stated end point. The action may have started in the past or the present. It may start in the future. However, we are only talking about the time that started before the future end point, which is given. In the Future Perfect Progressive Tense, however, the action is expected to continue after the later time that is noted.

Example

By 6:00 p.m., I will have been studying for three hours.

4.0 Perfect Continuous Tense

We may also use the future Perfect Tense to talk about the total time from the starting point, which could be the present or the past, until a time that is stated.

Example

By next May, I will have studied for 4 years.
  • Here, the end point is three years from now. The action may have started in the past or the present.

The perfect continuous tenses are used in the same way as the perfect tense, except that there is the expectation that the action will continue after the time of speaking or writing.
