练习材料：
We have an old musical instrument. It is called a clavichord. 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.

练习感悟:去年练这篇文章的时候胡思在感慨又落下了上一篇，今年第十天没有懈怠，下个目标应该是100天，期待我未来的90天我依然可以雷打不动的还在这里发表感悟。
