摩擦音(9個)

1、第七課?????????StepOne:Pronunciation摩擦音(9個)??英英對比?清輔音，唇齒摩擦音，發(fā)音時，上齒輕觸下唇，氣流從唇齒間的縫隙中經(jīng)過，引起摩擦，聲帶不振動。v濁輔音。唇齒摩擦音，發(fā)音與?相同，上齒輕觸下唇，氣流從唇齒間的縫隙中經(jīng)過，引起摩擦，聲帶要振動。漢英對比?的讀音接近于漢語的“府”。兩者區(qū)別之處在于：發(fā)?時上齒要壓住下唇，并且不能帶上“府”的韻母(u)的讀音，送氣要比“府”略強。?的讀音也接近于漢語的“

2、府”，但發(fā)v時聲帶要振動。??英英對比?清輔音，舌尖齒背摩擦音。發(fā)音時，舌尖輕抵齒背，氣流從舌齒間的縫隙中瀉出，形成摩擦音，聲帶不振動。?濁輔音，舌尖齒背摩擦音。發(fā)音時，舌位與?音相同，舌尖輕抵齒背，氣流從舌齒間的縫隙間瀉出，形成摩擦音，聲帶振動。漢英對比?的讀音接近于漢語的“死”，區(qū)別之處在于：發(fā)?時要用牙齒輕咬舌尖。?的讀音也接近于漢語的“死”，但在發(fā)音時要振動聲帶。s?英英對比s清輔音，舌端齒齦摩擦音，發(fā)音時舌端靠近齒齦，氣流由舌

3、端與齒齦瀉出形成摩擦音，聲帶不振動。z濁輔音，舌端齒齦摩擦音。發(fā)音與s相同，舌端靠近齒齦，氣流由舌端從齒齦間瀉出，形成摩擦音，聲帶振動。漢英對比s的發(fā)音與漢語的“絲”相近，兩者區(qū)別之處在于：發(fā)s時，舌要輕觸下齒背，送氣比“絲”強。z的發(fā)音只是s的濁化，在發(fā)音方法不變的情況下使聲帶振動。??英英對比?清輔音，舌端齒齦后部摩擦音。發(fā)音時，舌尖和舌端向上，齒齦后部抬起，舌身緊靠上顎，形成狹長通道，氣流由通道通過，形成摩擦音，聲帶不振動。?濁輔

4、音，舌端齒齦后部摩擦音。發(fā)音時，舌位與?相同，舌尖和舌端向上，齒齦后部抬起，舌身緊靠上顎，形成狹長通道，氣流由通道通過，形成摩擦音，聲帶不振動。漢英對比?的讀音接近于漢語的“噓”，但兩者的區(qū)別在于：發(fā)?時嘴唇撮成圓形并盡量往前突出，舌頭放平。?的讀音接近于漢語的“于”，區(qū)別之處在于：發(fā)?時嘴唇撮成圓形并盡量往前突出，舌頭放平，聲帶振動。?__?:tbri:__kl?u.__??__?:4.Thenreadafterthetape.sin
