主语

Verb and subject must agree in person.

词语人称必须一致。

The sentence reads “do the hoochie-coochie”.Now you’d never say, “Sister Cody do the hoochie-coochie.” Would you?

但在带有附加短语和从句的较长的句子里，语词不相连，这条原就难辨一些。

(grammar) serving as or indicating the subject of a verb and words identified with the subject of a copular verb.

（语法学）词的语，或相当于系词的语。
