So why haven't you stopped to ask if this is what I want?

"We passed it in the day, and did not stop to ask questions."

Don't stop to ask questions, but do what I tell you.

But if you've got any sense you won't stop to ask questions about this guy.

No one stopped to ask the boy what he wanted, which was to study science and work in the field of research.

So people stop him to ask, "Are we going to be all right?"

A couple of people stopped to ask if I was all right.

He won't even stop to ask if it makes sense or not.

He'd never stopped to ask whether this would be a good idea.

It was possible that he might stop in his way home to ask them how they did.
