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.
