疑问句句末韵律特征受语调和焦点等因素的影响。本研究从昌黎城关方言疑问句句末韵律特征出发，探究疑问语调目标的实现过程及其与词调的关系，并在句末控制焦点，从音高、音长两个角度考察焦点的实现方式。结果表明：（1）昌黎城关方言疑问句句末呈升调，疑问语调升调目标可通过利用词调的上升段、覆盖轻声、在降调后叠加一升尾三种手段实现，不同实现方式不会使目标词时长产生显著差异。（2）焦点有音高凸显作用，高目标焦点抬升音域，低目标焦点压低音域。当焦点目标与疑问语调目标重合时，焦点前所有音节的音域也会抬升；当两者不重合，即焦点作用于目标词前字时，目标词后字和焦点前音高无显著变化。（3）焦点会显著延长目标词音长，但音长手段不是稳定的、独立的焦点标记手段，是一种焦点凸显的伴随特征。（4）在昌黎城关方言中，高目标的疑问语调约束词调，使句末基频曲线全部上升；焦点则存在高、低音高目标，调节句子音高的起伏；疑问语调还会约束焦点对音高的调节作用。

The prosodic features of the interrogative sentences’ finals are influenced by intonation and focus. This study investigates the process of achieving the goal of question intonation and its relationship with lexical tone by looking at the prosodic features of the end of interrogative sentences in the Changli-Town dialect, and controlling focus of the sentences’ finals to examine how focus is achieved from two perspectives: pitch and length. The results show that: (1) The Changli-Town dialect has a rising tone at the end of interrogative sentences, and there are three ways to achieve the goal of rising tone in question: to achieve a rising segment of the lexical tone, to cover the light tone, and to superimpose a rising tone after a descending lexical tone, and there is no significant difference in the tone length of the target word according to the way it is achieved. (2) The focus has a pitch accentuation effect, with the focus raises the pitch on the high target, lowers it on the low target. When the final narrow focus target coincides with the question intonation target, the pitch of the pre-focus syllables is raised; when the two do not overlap, the pitch of the back word and pre-focus syllables has no significant change. (3) Focus significantly lengthens the length of the target word, but the length means is not a stable, independent focus-marking means. (4) In the Changli-Town dialect, the question intonation of high goal restricts the lexical tone and makes the f0 contour rise at the end of the sentence. Focus has high and low target and can adjust the sentence register ups and downs. Question intonation also constrains the effect of focus on pitch.
