A person I know learns English as a second language. The teacher introduced some basic grammar concepts, mostly simple present, past, and future. For some reason, he introduced present perfect as well. She showed me what he did on the whiteboard: he claims that present perfect is built using the s-form of the verb
and not using has/have + past participle
.
Does this mix-up make sense somehow?
Edit: I attached an image of the whiteboard. He explained that present perfect requires adding an "s" to the verb and is used when another person does something regular. For example:
She eats cereals every morning.
He walks the dog daily.
Edit: I removed the image again due to privacy concerns.
