I'm going to tell you something about an unusual P.E. class.
It was Tuesday yesterday and the weather was cloudy.
The last class in the morning would be a P.E. class.
While we were waiting on the playground, Mr. Wang, our P.E. teacher, didn't appear.
We were worried if we would miss our favorite class.
Just at that time, Mr. Gao, our math teacher, came and told us that Mr. Wang was ill.
We thought it might be another math class.
But Mr. Gao said he would give us the P.E. class.
All of us were surprised and then became very happy.
Mr. Gao played football with the boys and the girls played basketball and ping-pong.
We had a P.E. class by a math teacher.
Isn't it great?
