Question

How can I rewrite past simple sentences using present perfect?

Answer 1

I think the best I can do is a pair of simple examples,

Explanation:

Past Simple Example
`color(white)("XXX")`John went to the store.
The action took place some time in the past.

Present Perfect
`color(white)("XXX")`John has gone to the store.
The action took place at a time prior to the present moment.
