I have been teaching in Guangzhou for 12 years. I teach in a public middle school and high school. My PPT are all high quality as they have been changed almost every year to meet my high standards. Yes, my PPT are very long and many of them have few words. This is because I teach oral English and I think it is better for my students to hear me talk than to read the words. My classes are 40 minutes long, and some of my PPT are split into 2 lessons. If you are in China and you would like to contact me, my QQ number is 1182497989.
It seems the PPT is too large, so i have cut it into three files because there are many .gif files showing fun pranks. I will comment below with the second and third PPT
