摘要：Clefts and extraposition have structural and functional similarities, yet they
have been mostly treated separately. An investigation of the Wellington Corpus
of Spoken New Zealand English reveals cases where the two constructions
appear confounded and difficult to disentangle. The present paper argues that
they can indeed be differentiated, and provides a test which can be used to this
end. This work offers contributions of a practical nature, in that it provides
researchers with an objective criterion for distinguishing between clefts and
extraposition, and also in a more theoretical sense, in its focus on two important
strategies used in information packaging and discourse organization.
