Another issue of weekly Advanced grammar is here. Today we're going to check one of the rare perfect tenses, probably the rarest one - Future Perfect.
If you remember there are four different future tenses in English, yet only one of them is used on a daily basis to talk about the stuff of tomorrow.
Why does it happen? Well, all the future forms and tenses are a virtually new level of assurance in the future. And because no one has any belief in tomorrow we're basically using Future Simple for everything.
How sure should you use Future Perfect?
Well, very much sure. Future Perfect tells us about the action that sure will happen by a specific point in the future.
Long term predictions based on evidence
Snowcaps will have melted by 2050
Oil supplies will have run out by 2100
It doesn't have to be concrete evidence, just a good approximation.
A sincere belief in the future
Next year we will have been married for 10 years.
I will have become a doctor by the end of the year.
Again, it might not happen but based on the normal flow of the present, you pretty sure about the future.
The End
Future perfect is a really simple one, but you are not going to use it so often. Remember, if you are not sure about what future tense to use, go for Future Simple.
