Have you read a book under a tree?
I have purposefully taken a book outside to go read it under a tree.
I have happened to have a book with me when I saw a tree and sat down under it to read it.
Maybe. I’ve certainly had opportunities but I’m not sure if I actually have.
Probably not. I don’t read books often enough to make it likely.
Probably not. I don’t see suitable trees often enough to make it likely.
No. I’m pretty sure I’ve never read a book under a tree.
