I learned that present perfect is used with “since” when we talk about duration, something began in the past and continues to the present, with non continuous verbs, like:
I have known her since I was 5.
I don’t understand the following sentences, can somebody help me?
- He has met many people, since he came here
- I have done a lot, since we last spoke
- What have you eaten, since you got up this morning?
These are not non continuous verbs, are these sentences about duration?
