32页并列结构(并列结构(Coordinate Construction))l概念 A coordinate construction is a sequence of semantically-related grammatical units that are similar in form, equal in rank of structure, identical in function and are connected by coordinators.l不同层次的并列结构 trick or treat blue and white good but expensive a poet and a writer one way or the other with courage but without wisdom Jim may be wrong, but this doesn’t make you right.
