Hi Learneng,
Still going strong! I quite enjoy being tested on these, as my university students don't ask much about them. It makes for a nice change.
I have been making plans for this weekend since Monday.

My dog has been wagging her tail
for cookies for 10 minutes now (it's easier to comprehend the situation with the reason why being placed first, and the time second)
I have been lazing around for quite a while.

My dogs have been playing and enjoying each other's company.

She has been talking non-stop for fifty minutes now. (ha ha, who is this?)
