8. The Future Perfect

A. Form
will/shall + perfect infinitive


B. Use
It is normally used with a time expression beginning with by: by then, by that
time, by the 24th:
By the end of next month he will have been here for ten years.
It is used for an action which at a given future time will be in the past, or will
just have finished.
We’re late. I expect the film will already have started
by the time we get to the cinema.
In clauses of time and condition the Present Perfect is used instead of the
Future Perfect.

9. The Future Perfect Continuous

A. Form
will/shall have been + the present participle


B. Use

Like the future perfect, it is normally used with a time expression beginning

with by. The future perfect continuous has the same relationship to the future
perfect as the present perfect continuous has to the present perfect, i.e. the
future perfect continuous can be used instead of the future perfect:
1. When the action is continuous:
By the end of the month he will have been working here for five years.

2. When the action is expressed as a continuous action, i.e. if we are interested

in the action itself:
By the end of the month he will have been repairing cars.
But if we mention the number of cars we must use the future perfect:
By the end of the month he will have repaired 7 cars.

10. be + infinitive (I am to...)

This structure is often used to talk about arrangements which have been planned for the future. It is very much used in newspapers:
The Queen is to visit Japan next year.
There’s to be a rail strike on July 18th.
be + infinitive can also be used to give orders. (Parents often tell children to
do things in this way.)
You’re to do your homework before you watch TV.
Tell her she’s not to be back late.
