文法問題:Be動詞後接名詞例子, I am David,[專有名詞] Here is Taipei.[地方名詞當副詞]都理解,但是He is rhythm.你有節奏.是口語用法嗎?可否再多舉點例子,謝謝.?

In this pattern the auxiliary verbs, will/would, shall/should, can/could, must, dare, need are followed by a bare infinitive that fits:
eg:-He is rhymed adj --having rhymes; having rhymed verse.--rhythm n., accents, sounds in speech of events, processes, etc----rhythmic, adj, marked by rhythm; having rhythmic; the rhythmic accents of speaking in his speech=he is rhythmic
-
eg:- You may leave.
eg:- You need wait.
eg:- You'll find them.
eg:--I didn't dare tell.
eg:--You'd better start.
