HI,

The following is an article explaining an activity to practice the P.P. Continuous and i've got a question re the suggested sentences:

Example:

Accusation: You’ve been drinking again!

Suggested sentences:

We saw the empty bottle. =>COULDN'T WE SAY "We've seen the empty bottle"?
Your friends from the bar told us. => COULDN'T WE SAY "Your friends have told us"?,
We can smell it on your breath.
You aren’t walking straight.
Your eyes are red.

THANKS

We saw the empty bottle. =>COULDN'T WE SAY "We've seen the empty bottle"?

We could indeed.



Your friends from the bar told us. => COULDN'T WE SAY "Your friends have told us"?,

Maybe we could but we probably wouldn't.

Is the author American? Americans use the present perfect less often that Brits.
