|Internationally , will is now the standard choice for expressing future plans and expectations. However, in first-person questions shall is often used to express politeness, and in legal statements, shall is used with a 3rd-person subject for stating requirements.|
In practice, many speakers don’t commonly follow the traditional rule when using will and shall to express futurity. They don’t differentiate will/ shall and the present forms (especially going to ...) These verbs when used as future markers are largely interchangeable, as in:
|Will I play goalkeeper in the next game?(question about the future situation; no clear plans have been made)|
Am I going to play goalkeeper in the next game?
What are you doing this Friday evening?
What will you do this Friday evening?
What are you going to do this Friday evening?
|On one hand, both going to...and stressed will can express a strong determination, as in:|
|I’m going to pass this bar exams this time! I really will pass this bar exam!|
I’ m going to scale Mt. Everest. I will scale Mt. Everest!
