I am having a bit of trouble finding any rules about the past and future tesne of must. Using the word must in a future tense and past tense sentence is easy enough..
he must go to the doctor (f)
he must have gone to the doctor (p)
The word must changes it's tense with the use of auxiliary verbs.
Is it as simple and as straight forward as that? Do i need to explain that the negative of must is 'mustn't'?
Any advice on how to explain this to EFL students would be great. Thanks.
