Hi julielai:
I think the following are correct:
My favorite fruits are apples and odranges.
My favorite sports are tennis and basketball.
But I am confused as 'fruit' is not a countable noun and often exit in sigular form and is supposed to be followed by a singular verb. And as to 'sports', we often say: My favorite sports is tennis. Is it OK as well to say: My favorite sports are....?
Thank you for your patient.
