Lesson 10 Not for jazz
We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 2001. 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.

知识笔记：
单词：1、instrument：仪器、仪表；2、shock：使不悦或使震惊。
音标：/ɔː/：call，clavichord，for，bought，
/ɔː/是元音音标，属于单元音、后元音及长元音。发音时嘴唇收圆，稍向前突出，舌身后缩，舌后部抬起，由喉部发出类似汉语拼音“o”的音。
练习感悟：等一下要去出差，本来以为十来分钟可以搞定，事实证明不能专注做一件事效率肯定低，struck我总是会读成struckt，静下心来专门练了这一句很多次，反复听自己的录音，终于不再错了。
