USE

1. Duration Before Something in the Future

We use the Future Perfect Continuous to show that something will continue up until a particular event or time in the future. "For five minutes," "for two weeks," and "since Friday" are all durations which can be used with the Future Perfect Continuous. Notice that this is related to the Present Perfect Continuous and the Past Perfect Continuous; however, with Future Perfect Continuous, the duration stops at or before a reference point in the future.

• Stephanie will have been working here for 10 years by the time she is a store manager.

• Will you have been learning French for 2 years by this month?

2. Cause of Something in the Future

Using the Future Perfect Continuous before another action in the future is a good way to show cause and effect.

• I will be exhausted when I come home because I will have been training for 3 hours.

• My maths will be very good in next year because I will have been studying it for over 4 years.

3. Active/Passive

• By the end of December I will have been reading a book for a year. ACTIVE

• A book will have been being read by me by the end of December for a year. PASSIVE
