Unit Twenty-one 音标名称 破擦音 [t?] [d?] [tr] [dr] [ts] [dz] 语音知识和读音规则 辅音连缀 （二） 元音的省略 连读  破擦音 按发音方法分, [t?] [d?] [tr] [dr] [ts] [dz] 这几个音是破擦音。破擦音是爆破音和摩擦音的结合。发爆破音时,憋住气流的发音器官(舌尖和上齿龈)分开得比较缓慢,而且立刻跟着发一个发音部位相似的摩擦音。发破擦音时,先形成阻碍,在解除阻碍的同时舌尖向摩擦音的部位滑动,发出摩擦音,但这两步动作是紧密相连的,由一次送气来完成,不可发成两个独立的音。 ? 音素复习  语音练习 1) Read the following words and pay attention to he consonant clusters.
