17、，编辑于2022年，星期二An example of an interpretable feature is the plural inflection on regular English nouns,e.g.dogs.The word dogs can only be used to refer to several dogs,not a single dog,and so this inflection contributes to meaning,making it interpretable.English verbs are inflected according to the n

21、permits both binary and unary branching.4.BPS does not distinguish between a“head”and a“terminal”,while some versions of X-Bar Theory require such a distinction.第30页，共38页，编辑于2022年，星期二BPSincorporatestwobasicoperations:Merge(合并)andMove(移动).Merge is a function that takes two objects(say and)and merges

24、water,the label is drink since the phrase acts as a verb.For simplicity,we call this phrase a verb phrase or VP.Now if we were to Merge cold and water to get cold water,then we would have a noun phrase or NP with the label water.The reader can verify that the phrase cold water can appear in the same
