Dear Casey,
You asked in your last letter about my spare
time activities. Well, I like much more than one, 76．_____________
such as painting and model making, so my favourite 77．_____________
is dancing. I started when I was eight year old, 78．_____________
and it is a great fun! Dancing is not difficult. If 79．_____________
you want to do it good, you need to find a good 80．_____________
dancing teacher and taking lessons regularly. 81．_____________
That’s I did and I also had to take exams every 82．______________
six months. Now, I had stopped going to lessons. 83．______________
But I sometimes take part performances at the 84．______________
school, that I really enjoy very much. 85．______________
