Comment on Verb Tense - Perfect Tenses

how about " After June learned to drive, she felt more independent."

That would be fine, since the order in which the events occurred is obvious (as noted at 8:00 in the video)

Amazing video. Was searching for something of this kind.

When do we use "would have" in a sentence?

We use "would have" in a type of conditional sentence called "third conditional"

Hi Brent,
Referring to the sentence at 06:50, is it incorrect to say "Prior to 1995, Harry visited Peru several times." ?

Yes, that's acceptable because we can be certain that the visiting occurred before 1995. This idea of eliminating "had" is discussed at 7:15 in the video.

Hello Brent,
Why is it possible to say "Warren will have arrived at work before his boss gets out of bed." since the the boss gets out of bed in the future and I would suggest to use the will-future. So my suggestion is: "Waren will have arrived at work before his boss will get out of bed".
Thank you again and best

Hi Eric,

Your suggested sentence is also fine.

The sentence "Warren will have arrived at work before his boss gets out of bed" is also fine because it use the simple present tense ("gets"), which can describe a repeated or habitual action (which may or may not be happening now).


Hi Brent,

Will the fence painting example work the following way?

Fred had painted the fence red first, buy Amy has painted it white ever since. (or)
Fred had painted the fence red first, but Amy has been painting it white ever since.

Both are grammatically correct, but the second sentence uses more words than are necessary. That is, "been" does not add any value to the sentence.


Hey Brent,
In the last sentence 'On May 29, Brat will have served as Mayor for 3 years' both the actions are occurring at same time i.e May 29 and 3 years of serving. So why future perfect tense?

"May 29th" and "3 years of serving" both occur in the future. However, the event "3 years of serving" will end on May 29th.

Since the future event of "serving 3 years" will end before the future event of "May 29th", we need future perfect tense.

That is, BEFORE May 29th, we cannot yet say that Bart has served for 3 years. However, at the very moment May 29th arrives, we can say that Bart has served for 3 years. So, at the moment May 29th starts, the 3 years of service has been completed.

Does that help?


That helps. Thanks!

“Cranston is one of a number of celebrities who have sworn off giving autographs, which can have a monetary value.”

Hi Brent,

Is the sentence above correct all round in grammar and structure. Are the modifiers and tenses being used correctly? Thanks!

I think the sentence is fine.
I like the use of "which," because we're talking about Cranston's autographs, and "which" just tells us a little more about those autographs (they have monetary value)


Thanks for the lessons.

Please is it okay to say "Since 1973, Frank's diner has been providing a free soda with every burger"

That sentence is a little wordy (although not necessarily grammatically incorrect) since the word BEEN adds no value. We could just say, "Since 1973, Frank's diner HAS PROVIDED a free soda with every burger"

Please is it correct to say "Prior to 1995, Harry visited Peru several times" ?

Yes, that sentence is acceptable since "PRIOR TO 1995" clearly indicates the order of past events.
