This paper investigates the distribution of focus-related accents in the broad focus domain in Chinese Mandarin through 300 natural sentences. The results show that focus-related accent tends to be assigned to the predicate in a subject-predicate structure, to the object in a predicate-object structure, and to the head in an adjunct-head structure unless the head is highly predictable. From these observations, we conclude that, in a broad focus structure in Chinese Mandarin, the focus-related accent is normally assigned to the innermost constituent of the sentence if this constituent has enough semantic weight; otherwise, the accent is placed in the constituent that has the closest syntactic relationship to the innermost one.
