(2)

發問者的要求是 adj 及 adv 的 例子sss, 而不是兩者的分別. 不知投 1 號者是否認為 first 此一例子比我舉出的6個更有代表性呢? :)

Yes there is
adjective is part of speech used to modify a noun
adverb is part of speech used to modify verbs, adjectives and other adverbs

Example:
“first”
adj:
the first(adj) month(n) of the year
adv:
Which house come in first(adv) won(v) the race

That what i can think of now
