Duration Before Something in the Past

admin — Wed, 16 Jul 2008 19:05:35 +0000

We use the Past Perfect Continuous to show that something started in the past and continued up until another time in the past. “For five minutes” and “for two weeks” are both durations which can be used with the Past Perfect Continuous. Notice that this is related to the Present Perfect Continuous; however, the duration does not continue until now, it stops before something else in the past.

Examples:

They had been talking for over an hour before Tony arrived.
She had been working at that company for three years when it went out of business.
How long had you been waiting to get on the bus?
Mike wanted to sit down because he had been standing all day at work.
James had been teaching at the university for more than a year before he left for Asia.
A: How long had you been studying Turkish before you moved to Ankara?
B: I had not been studying Turkish very long.

Specific Times with the Past Perfect

admin — Wed, 16 Jul 2008 19:05:11 +0000

Unlike with the Present Perfect, it is possible to use specific time words or phrases with the Past Perfect. Although this is possible, it is usually not necessary.

Example:

* She had visited her Japanese relatives once in 1993 before she moved in with them in 1996.

MOREOVER

If the Past Perfect action did occur at a specific time, the Simple Past can be used instead of the Past Perfect when “before” or “after” is used in the sentence. The words “before” and “after” actually tell you what happens first, so the Past Perfect is optional. For this reason, both sentences below are correct.

Examples:

* She had visited her Japanese relatives once in 1993 before she moved in with them in 1996.
* She visited her Japanese relatives once in 1993 before she moved in with them in 1996.

HOWEVER

If the Past Perfect is not referring to an action at a specific time, Past Perfect is not optional. Compare the examples below. Here Past Perfect is referring to a lack of experience rather than an action at a specific time. For this reason, Simple Past cannot be used.

Examples:

* She never saw a bear before she moved to Alaska. Not Correct
* She had never seen a bear before she moved to Alaska. Correct

Duration Before Something in the Past (Non-Continuous Verbs)

With Non-Continuous Verbs and some non-continuous uses of Mixed Verbs, we use the Past Perfect to show that something started in the past and continued up until another action in the past. Examples: * We had had that car for ten years before it broke down. * By the time Alex finished his studies, he had been in London for over eight years. * They felt bad about selling the house because they had owned it for more than forty years. Although the above use of Past Perfect is normally limited to Non-Continuous Verbs and non-continuous uses of Mixed Verbs, the words “live,” “work,” “teach,” and “study” are sometimes used in this way even though they are NOT Non-Continuous Verbs.

Completed Action Before Something in the Past

The Past Perfect expresses the idea that something occurred before another action in the past. It can also show that something happened before a specific time in the past.

Examples:

I had never seen such a beautiful beach before I went to Kauai.
I did not have any money because I had lost my wallet.
Tony knew Istanbul so well because he had visited the city several times.
Had Susan ever studied Thai before she moved to Thailand?
She only understood the movie because she had read the book.
Kristine had never been to an opera before last night.
We were not able to get a hotel room because we had not booked in advance.
A: Had you ever visited the U.S. before your trip in 2006?
B: Yes, I had been to the U.S. once before.

Recently, Lately

You can also use the Present Perfect Continuous WITHOUT a duration such as “for two weeks.” Without the duration, the tense has a more general meaning of “lately.” We often use the words “lately” or “recently” to emphasize this meaning.

Examples:

Recently, I have been feeling really tired.
She has been watching too much television lately.
Have you been exercising lately?
Mary has been feeling a little depressed.
Lisa has not been practicing her English.
What have you been doing?

Duration from the Past Until Now

We use the Present Perfect Continuous to show that something started in the past and has continued up until now. “For five minutes,” “for two weeks,” and “since Tuesday” are all durations which can be used with the Present Perfect Continuous.

Examples:

They have been talking for the last hour.
She has been working at that company for three years.
What have you been doing for the last 30 minutes?
James has been teaching at the university since June.
We have been waiting here for over two hours!
Why has Nancy not been taking her medicine for the last three days?

Duration From the Past Until Now (Non-Continuous Verbs)

admin — Wed, 16 Jul 2008 19:01:41 +0000

With Non-Continuous Verbs and non-continuous uses of Mixed Verbs, we use the Present Perfect to show that something started in the past and has continued up until now. “For five minutes,” “for two weeks,” and “since Tuesday” are all durations which can be used with the Present Perfect.

Examples:

I have had a cold for two weeks.
She has been in England for six months.
Mary has loved chocolate since she was a little girl.

Although the above use of Present Perfect is normally limited to Non-Continuous Verbs and non-continuous uses of Mixed Verbs, the words “live,” “work,” “teach,” and “study” are sometimes used in this way even though they are NOT Non-Continuous Verbs.

Time Expressions with Present Perfect

admin — Wed, 16 Jul 2008 19:01:12 +0000

When we use the Present Perfect it means that something has happened at some point in our lives before now. Remember, the exact time the action happened is not important.

Sometimes, we want to limit the time we are looking in for an experience. We can do this with expressions such as: in the last week, in the last year, this week, this month, so far, up to now, etc.

Examples:

* Have you been to Mexico in the last year?
* I have seen that movie six times in the last month.
* They have had three tests in the last week.
* She graduated from university less than three years ago. She has worked for three different companies so far.
* My car has broken down three times this week.
