Difference between 'hear' and 'hear of/about something'

[for2000]

please give me examples as much as you can:
"hear something", "hear about something" and "hear of something".

Many thanks

'To hear' (to be told): have you heard the news? Have you heard that there's going to be a new show on TV?

'To hear about' (to find out a piece of information): I've never heard about that village before; did you hear about the new project?

'To hear of' (to be informed about, to be familiar with, to learn of): he’s never heard of Oscar Wilde (doesn’t know who Oscar Wilde was); has anyone heard of the new virus?
