Where are the resonating cavities of human beings?

正确答案：The three resonating cavities are：pharyngealoraland nasal．And among them the mouth is the most important．These three cavities are connected with one another．They are involved closely with place of articulation and manner of articulation．The pharynx stretches from the top of the larynx up to the back of the nasal cavity．And the latter is connected with the mouth．When the soft palate is drawn back and uvula is raisedall air existing from the lungs can only go through the mouththus producing non-nasal sounds；if the action is reversed(with the soft palate and uvula being lowered)nasalized sounds will result． 人类的发音的共鸣腔包含在三个腔中：咽腔、口腔、鼻腔其中口腔最重要。这三个腔互相连接它们与发音部位和发音方法有密切关联。咽腔从喉头的上部延伸到鼻腔的后部前连口腔。当软腭和小舌抬起时肺部排出的气流只能从口腔通过这时发出的音不属于鼻音；相反(当软腭和小舌下垂)关闭口腔通道气流由鼻腔通过这时发出的音为鼻音。
