Refusal, Formal Instructions, and Assumptions
Advanced nuances:
ā¢ Refusal: "The car won't start." (The car refuses to start). "He won't listen."
ā¢ Assumptions/Deductions: "That will be the postman." (Deducing it IS him now/soon).
ā¢ Formal Instructions (Shall): "All students shall submit..." (Rules/Regulations).
ā¢ "Be to" usage: "You are to report at 0800." (Formal obligation).
ā¢ "Be about to": Immediate future. "I was just about to call you."
