Future Perfect Continuous Tense

hunterxhunter is quite right.

I agree.

future perfect continous tense is seldom used, but it really focuses on the process, just like,

I will have been doing this job for three years in 2007
I will have done this job for three years in 2007

The first sentence means that you might or might not continue to do this job in 2007 but the second sentence means that by 2007, you have done this job for 3 years, doesn't contain any indication of continue to do it or not.

By the way, there is DEFINITELY future perfect continuous tense, it's just that we seldom use it, doesn't mean that it does not EXIST!

for example :
By the end of this year he will have been acting for thirty years .

Compare :By the end of the month he will have been training horses / climbing mountains for twenty years . ( Future Perfect Continuous Tense )By the end of the month he will have trained 600 horses / climbed 50 mountains .( Future Perfect Tense )

Future Perfect Continuous Tense即係未來完成進行式

以我所知,係冇未來完成進行式。

ex:do

未來式:will do/shall do

完成式一定要夾現在/過去/未來

現在完成式:have/has done

過去完成式:had done

未來完成式:will have been done

進行式一樣:

現在進行式:am/is/are doing

過去進行式:was/were doing

未來進行式:will being done

完成進行式唔可以未來

現在完成進行式:have been doing

過去完成進行式:had been doing
