Презентация на тему Future simple

/ -ed

The Future Perfect expresses the idea that something

will occur before another action in the future. It can also show that something will happen before a specific time in the future.
With Non – Continuous Verbs and some non-continuous uses of Mixed Verbs, we use the Future Perfect to show that something will continue up until another action in the future.

shall be + Ving

The most common use of the Future

Continuous Tense is to describe an activity that will occur in the future and continue for a certain period of time.

The Future Continuous is also used when we talk about an activity that will continue over a period of time from now into the future 

have + been + Ving

Using the Future Perfect

Continuous before another action in the future is a good way to show cause and effect.
Like all future forms, the Future Perfect Continuous cannot be used in clauses beginning with time expressions such as: when, while, before, after, by the time, as soon as, if, unless, etc. Instead of Future Perfect Continuous, Present Perfect Continuous is used.
