what a terrible thing

   I have been in Dezhou for some days. During the days here, I am very busy. When the first day I came here, I went to the class for classes, on that day I had four classes, I was very tired. But it is not the last thing. I teach biolgy in this school which is not my major, my major is English. Since I have not learned biolgy for some years, so I can't teach it at all. Begore I teach my students, I listen to some other teacher's class first.

  What a terrible thing!
