Adverbial scope of ‘tomorrow’
For the following sentence; I suppose the adverbial scope of ‘tomorrow’ only covers the verb ‘work’
ie. I have to (work tomorrow).
Where ‘have to’ refers to present obligation.
What about this:
Tomorrow I have to work.
Here it ‘tomorrow’ is emphatic and ‘have to work’ seems to be within its adverbial scope. Thus ‘have to’ here appears to mean a future obligation - of tomorrow. I think there’s a difference between both sentences. Any opinions?
