The paper explores the potential of English sentences with the verb have to constitute the Presentation Scale. Have-presentative sentences, in which the verb is devoid of its possessive meaning, can be viewed as an alternative to the "full presentative" there-constructions.

There's a long trip ahead of us. Presentative sentences with have are described and classified with respect to the animacy, semantics and reference of the subject, the presence of a locative adverbial, and the semantics of the object.
