My professor traveld on official business, I had no class today. I was very happy. Because that class started at 9a.m. I always go to school at 9a.m , but today’s not. I could sleep until 9a.m, but I got up at 6a.m and I got ready to go to school. Because the mid-test is coming, so I have to study more and more. So I went to school at 9a.m. ,and studied ‘science’.  I felt satisfied.
