好人做到底，多年的總結送給你

/l/

在元音後（在詞尾）有兩種發法，第一種是你在單詞中的讀法，舌尖不抵住上齒齦；第二種是：

-          The tongue tip and a portion of the tongue blade contact the alveolar ridge in the midline
舌尖抵住上齒齦或上牙，兩門牙中間，（舌麵不要平鋪，要變成細舌）。

-          Lip configuration may vary depending on phonetic context
嘴唇不要變化 （尤其不要前突）。

-          The vocal folds are abducted and vibrating

-          The velopharyngeal port is closed

-          Acoustic energy radiates laterally, around midline closure

-         

 

 

/r/

-          The tongue is elevated towards the hard palate in a bunched configuration

-          The front of the tongue is usually close to the alveolar ridge but may be retroflexed.

-          The lips are slightly unrounded

-          The vocal folds are abducted and vibrating

-          The velopharyngeal port is closed
