Lesson 10 Not for jazz

We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belonged to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's.

1）双唇收圆而且小，并向前突出，牙齿接近闭合。

2）舌身后缩，舌尖离开下齿，舌后部向软颚抬起，但不要接触到软颚。

3）嘴部肌肉是收紧，震动声带。

3. 今天是第十天: 前元音和后元音是按照舌头在口腔里面靠近上颚的位置来区别的，前元音舌靠近下齿且比舌后部高；而后元音则舌头向后收并使舌靠向上颚而比前部高。
