2. Function of Simple Future Tense
The Future Simple tense has two functions:
To talk about something that will or will not happen in the future (e.g., I will never retire from teaching ESL to adults.), and
To express willingness (e.g., Mary: "Someone is knocking at the door." John: "I'll get it.")

5. General Rules: Here are the general rules for will vs. be going to:
(1) Predictions: Both will and be going to can be used to make predictions about the future.
Ex) Take your umbrella. It's going to rain.
The weather channel said it will rain tomorrow.
Ex) Be careful. That dog is going to bite you!
Don't cheat. You'll get caught.
(2) Prior Plans: "Be going to" is used to express plans previously made for the future. You cannot use "will" for this purpose.
Ex) I'm going to meet my friends this weekend.
She's going to take a vacation this summer.
We're going to go to the library tonight to study.
(3) Willingness: "Will" is used to describe willingness to do something.

A. Someone's at the door.
B. I'll get it.
Example 2:
A. I can't do this by myself.
