myteacheryyo: SIMPLE FUTURE

Future can be expressed in English in several ways but to express the Simple Future there are three main forms: present continuous, be going to and will. Although the present continuous and be going to or be going to and will can sometimes be used interchangeably, they often express very different meanings.

USE.

PRESENT CONTINUOUS	Used for a planned activity and you have arranged to do it	Tomorrow I'm playing tennis
(BE) GOING TO + VERB	Used for a planned activity that you intend to do	Tomorrow I'm going to swim in the sea
WILL + VERB	Used when you decide to do something at the time of speaking, when you say it.	OK, I'll come to the party!

Sometimes the difference between present continuous and going to is very little so both forms can be possible.
