Huevos“The difference between the simple past and the present perfect is just a slight "Sss" sound. "somebody shot the president" versus "somebody's shot the president".”
Hi Huevos
If you are a native speaker, then I'm sure you also realize that a native speaker will understand whether that 'sss' sound is there or not. In other words, a native speaker knows whether someone is saying
somebody's or
somebody. What I'm saying is that in the scenario I gave, I think it is
far more likely that an American will use the simple past tense. There won't even be a slight hint of a 'sss' sound connected to the end of the word 'somebody' -- because it just won't be there.
As regards "I ate already", Americans commonly use the words
already,
yet, and
just (for example) with the simple past tense -- especially in spoken English:
- Did you see that movie yet?
- I just saw that movie.
- I already saw that movie./I saw that movie already.
Naturally, we use
already,
yet, and
just with the present perfect as well.
