Phase

相

A term used by some grammarians to refer to the contrast between perfect and nonperfect in the verb phrase (of English, in the first instance). The term is intended to distinguish these forms from the progressive/non-progressive contrast within aspect, and also from the contrasts of tense and voice.

有些语法学家用来指（最初指英语中）动词短语完成时和未完成时的对立。这个术语意在将其区别于体的进行体/非进行体的对立、时和态的对立。
