Interested in Language
We have been talked in school or from grammar books that the noun/noun phrase before an of-phrase usually takes a definite article. However, according to my reading expereince, there are other variations beside this, such as "a/an +of a/an, the + of the/a/an, and zero article + of the/a/an". So, dear teachers, could you tell me with examples under what situations those variations are used? Thank you.
