1)A woman fell 50 feet down a cliff.
2)The project was finished 10 days ahead of the schedule.
3)Emma is 10 years older than Sophie.
4)I finished the project 10 days ago.
1)50 feet/10 days/10 years/10 days
I think of them as Noun phrases.
2)down a cliff/ahead of the schedule/ago
They are considered as the adverbial phrases.
Is it right?
I know that the noun phrase can’t modify the adverbial phrases, but in this cases, they are not only closely related to the adverbial phrases above but also semantically seem to qualify the latter.
I remember Noun can function as the main elements of subjects of verbs (A dog just barked), or of objects of verbs or prepositions, except for compound noun phrase. Someone tells me that the noun phrases is used as the adverbial phrase here, so they can modify the latter.
Suppose that he is right. Then, is it also correct that the "pseudo" adverbial phrases should modify the real adverbial phrases?
