Future action...

[I_rock_theworld]

Could someone explain when do we use "will" and "be+ going to" for the future action ?

You use 'will' to predict some actions in the future:

I think she'll pass her driving test.

However, if your prediction is based on present events, or past actions that made you feel certain about something, you can use 'be going to':

I truly think she's going to pass her driving test. She's improved so much since her first drive.

There's something more to the topic, you know.

If you want to do something, and the decision to do it is being made at the time of speaking, you use 'will':

"What would you like to drink?" "I'll have a coke, please."

If you have already planned something to do, you use 'be going to':

I've been thirsty all day; I'm going to drink some beer at the pub after work.

You use 'will' for offers, requests, promises, and threats:

Oh my goodness! Your bags look really heavy. I'll carry one of them for you, OK?

Will you carry one of these bags for me, please?

Ok, I'll get you that toy car for your birthday.

Give it to me right now, or I'll do something that...

That's more like it.
