1. We have not seen....yet
She has already visited
Has Tom ever talked about....
I have never learned .....
Have you finished.... yet
2. I have flown
He has taken
I have always enjoyed
I have never felt
I have flown
I have not been
Have you ever flown
We have just returned
I have had
I have never been
3. Mountain biking is funny
Speaking english is cool
Walking down the streets is srared
Eating fruits is healthy
wearing this ring is lucky
