2. When can we use the present perfect?
We use the Present Perfect to say that an action happened
at an unspecified time before now. The exact time is not
important. You CANNOT use the Present Perfect with
specific time expressions such as: yesterday, one year ago,
last week, when I was a child, when I lived in Japan, at
that moment, that day, one day, etc. We CAN use the
Present Perfect with unspecific expressions such as: ever,
never, once, many times, several times, before, so far,
already, yet, etc
