I could hardly believe what I was seeing.
She could hardly believe her eyes.
She can hardly hear you in this noise.
We can hardly see anything in the fog.
He can hardly walk after the long hike.
They can hardly wait to see the results.

We can hardly finish on time without help.
He hardly gets used to speaking in public.
She can hardly concentrate when she’s tired.
They can hardly understand the instructions.
He can hardly speak because he lost his voice.
