Perfect forms - Simple or Progressive?

Explanation and Quiz

By

There are two types of perfect tenses; simple perfect tenses (present perfect, past perfect and future perfect) and progressive perfect tenses (present perfect progressive, past perfect progressive and future perfect progressive). The perfect forms are generally used to represent something that has happened up to another point in time. For example:

Present

Peter has visited Paris twice. (In his life, up until now)
Jane has been playing tennis for two hours (until now)

Past

They had lived in New York for 3 years before they moved to Seattle. (up to the time they moved to Seattle)
She had been studying for 4 hours when he arrived. (The four hours directly before he arrived)

Future

We will have finished the course by this time next year. (up to this time a year from now)
I will have been working for 2 hours by the time he arrives tomorrow. (the two hours before he arrives tomorrow)

So, what are the differences between the simple and progressive forms of the perfect? Well, first of all remember to keep in mind the progressive is only used with ACTION verbs (see last week's feature for examples of non-action or state verbs). Another important difference is that we use the simple perfect forms to express finished QUANTITIES and the progressive perfect forms when we are stressing the continuous duration of a specific action mentioned.

Now, let's take a look at the specific differences between the two forms:

PRESENT PERFECT PROGRESSIVE

1) Recent activity: to emphasize the recency of a past activity. we often use lately or recently - Example: She's been working hard recently
2) Emphasis on the duration or length of an activity - Example: Jack has been painting for 4 hours.
3) Recently finished activity with a present result - Example: I've been working in the garden, that's why my hands are so dirty.
4) No difference in meaning. Often the present perfect progressive and the present perfect can have the same meaning. This is often the case with verbs of living, occupation or vocation) - Example: I've been living in Leghorn for 3 years. OR I've lived in Leghorn for 3 years.

PRESENT PERFECT

1) Indefinite time in the past (experience). Emphasis is on the completed action at an indefinite time in the past. - Example: Susan's written 3 books.
2) Emphasis on QUANTITY - Example: I've read 300 pages of Tom Smith's latest book.
3) Duration from past to present (see #4 of present perfect progressive) - Example: Peter has worked for that company for 5 years.



Here is an excellent example of the difference between the two forms when referring to duration of an activity as compared to quantity:

He's been driving for 6 hours. He's driven 320 miles.

Past

PAST PERFECT PROGRESSIVE

Past perfect progressive is used to express CONTINUOUS activity up to a specific point of time in the past.
Example: They had been waiting for 2 hours before their friends finally arrived.

PAST PERFECT

Past perfect is used to express FINISHED activity before a specific point of time in the past.
Example: He had already eaten when his wife came home.


Future

FUTURE PERFECT PROGRESSIVE

1)
Future perfect progressive is used to emphasize the length of time or duration of an event occurring before and up to another event in the future. - Example: By the time they arrive, we will have been waiting for 4 hours!
2) To emphasize the duration of an activity. - Example: John will have been studying for 6 years by the time he finishes his exam.

FUTURE PERFECT

1) Future perfect is used to refer to an event completed before another future event or time. - Example: By the time Mary finishes this course, she will have taken 26 exams.
2) To emphasize not how long something has taken, but that the action is completed. - Example: By the time he retires, he will have worked for 36 years.
