In a way phrases with “since” are like mixed conditionals. Nothing is straightforward. Nevertheless, its multiple functions make this little word interesting. Now draw a (time) line with since in the middle as follows:
The following configuration is possible:
1. As adverb of time - Present perfect (before) - past simple (after )
He has been ill since he started work
2. It can come in end position either alone in collocation with ever. (present perfect)
I haven’t seen him since (ever since)
2. Since as a conjunction
- Present perfect simple/continuous before- past simple after
- Present simple before – present perfect after
- Past simple after – Present simple in the main clause
He has been working here since he moved house
Since in a clause can be followed by perfect tense:
It is ages since I have travelled by air.
Since I saw her I can’t stop thinking of her
3. Since - phrases can express temporal location or duration:
I have been lonely since you left (temporal location)
I have been here since three O’clock. (duration)
Of course you can use past simple instead of present perfect:
since we signed the agreement
But then you change your emphasis and perspective or focus. Both are correct.
Sorry to insist but I've had so many interpretations and views that I don't know what what I should do / write in the end. Would you please give me a definite (if possible) answer to the following questions?
1) Is it acceptable in written English to say:
a) My My mother looks younger since she dyed her hair.
b) My mother has looked younger since she dyed her hair.
c) Until when are you going to stay here.
2) How would you justify the use of the present with "since" in the following sentences?
a) Since when (standard ?) do you have the right to tell me what to do?
b) My kids think that the cell phone is the greatest thing since sliced bread.
Is the use of the present allowed with stative verbs? Why?
Thank you very much for your patience.
My mother looks younger since she dyed her hair. OK
My mother has looked younger since she dyed her hair. no
Until when are you going to stay here? no
(Say: "When are you going to leave?" or "How much longer are you going to stay?")
Since when do you have the right to tell me what to do? OK
(A rhetorical question.)
My kids think that the cell phone is the greatest thing since sliced bread. OK
(A common type of expression.)
Question:Is the use of the present allowed with stative verbs?Is the present tense used with stative verbs? Yes.
Is the present progressive used with stative verbs? No.
(It is not a question of whether it is allowed or not.)
