If my father heard you, there would be fresh trouble.

I think my father should hear the tale you tell.

Finally my father has heard me and he opens the door.

Her father must have seen or heard the ship coming in.

"How do you account for what my father saw and heard there?"

Her father was already up, but hadn't heard the phone.

But his father would not even hear of the fight.

Her brother and father would probably have heard of it too.

His father was away at sea and didn't hear until two weeks later.

There is something to be said for the fact that my father cannot hear a thing.
